0438.2 Story of the Issue

***Display Interfaces Symposium 2004
By John Latta

Milpitas, CA
Sept. 16 – 17, 2004

This is the fourth year of this event. It is small, about 150 attendees, at a location not far from the headquarters of VESA here in Milpitas, CA. The VESA plays a critical role in developing standards for displays in the PC industry. Yet, as the display becomes the centerpiece for the HD television emergence there is increasing overlap between CE and PC displays. In the CE world it is called the television and in the PC world it is the monitor. The display manufactures are winners in both worlds. Increasingly a high quality PC monitor is able to serve CE roles. As the issues of grey to grey transitions and viewing angle are addressed, the LCD panel increases its dominance as the display technology of choice. But every one here recognizes the mass confusion in the CE market around HD. The issues are an echo of many we have heard in the past: price, what display technology to buy and where is the content? Under-the-table fair use and copy protection are major market impediments. The content producers want increasingly robust protection for their golden nuggets while the consumers have yet to vote with their wallets/purses on the most onerous “secure” technologies which squash what the consumer thought were their “rights” with media. Here at Display Interface Symposium this new secure future was hinted at with Blu-Ray, potentially the most secure HD content source. It remains to be seen if consumers share the enthusiasm of Hollywood.

If there is one difference between the PC and CE industry it is in return policies. The CE companies live in fear of the return product flow. Viewsonic cited statistics which showed the 30 day product return rates, with earlier technology, were 60 percent and have now settled down to 30 percent. Of the returns, 80 percent tested as without fault. As the PC industry seeks to penetrate the CE industry it has to face the “big box stores” and the reality of fickle consumer.

Are We Making the Consumer Look Dumb?

Alfred Poor, free lance writer, gave an overview of the state of convergence which he called “Convergence: The Points of Confusion.” Some of his key points included:

There remains a significant price disparity between 20 inch televisions and monitors. Yet, at the high end with LCD technology, these prices are narrowing.

The display industry does not have its consumer act together. We burden the consumer with meaningless acronyms, countless connector variations, uninformed sales staff seen to foist products on confused consumers and crazy pixel defect policies.

Alfred ended with the plea to think about ease of use, interoperability, reliability, versatility and value.

Bottom Line

Only the most determined will buy the new display technologies. Sad, but there is a lot of reality to this.

CEA Standards for HDTV Networking

Jack Chaney, Samsung, gave an interesting presentation on the development of the CEA-2027 standard for high bandwidth networking in the home based on 1394.

Note that this is quite the opposite of the direction that the Digital Living Network Alliance (DLNA), formerly known as the Digital Home Working Group, has taken. The DLNA has avoided 1394, in part, based on Intel’s desires to avoid the technology whose IP is held by TI.

The emphasis in Jack’s presentation is support for the device control functionality. This uses cascading style sheets to present GUI components on display screens. The intent is that the network will support many products irrespective of vendor. Some of the examples of the UI looked appealing.

Making Display Convergence Real

Ruston Panabaker, Microsoft HIG, outlined Microsoft’s approach to accomplishing display convergence. That is, how to make many displays work on the PC. The emphasis is on accomplishing this with Longhorn. The intent is that display connectivity will work in an optimal fashion when connected to a PC. A major issue is overscan, which is the norm in television production and output to television sets. This causes significant limitations in displaying PC screens, especially the menu bar, which spans the full screen.

Back to the Future with an Analog Display Interface

To the surprise of many, VESA has developed the New Analog Video Interface Standard (NAVI). This is backward compatible with the existing VGA standard and connector. However, there is also a new connector which can be used. Of course, the first question to be answered in this presentation is – why a new analog interface? The short answer is that digital interfaces have failed to displace analog. The reality is that digital offers “few if any” advantages over a properly implemented analogy interface. As a result there is a NAVI feature set which includes:

VGA compatibility

Smaller optional connector

Hot Plugging

Audio support

Bidirectional power – either to or from the display

Data communications, minimum 2.7Mb/s

Seems like we have been here before? Was not DVI to be the end game for digital display interfaces?

Cell Phones on a Roll

George Wiley of Qualcomm spoke of the MDDI display standard. At the same time he gave a compelling look into the future of cell phones. MDDI is the Mobil Display Digital Interface. It is a high speed wired digital interface. One might raise questions why this applies to a cell phone but this standard has a major advantage of simplifying the connections between two sides of a flip phone. It takes literally 100 lines and reduces them to 6 which run at rates up to 400Mbs. A further gain is that it is possible to use MDDI to drive displays external to the phone. Examples cited include large screen displays, head mounted displays, projectors and external monitors.

By far the most interesting part of the presentation was Qualcomm’s road map for baseband chips. Sampling in 2005 with products expected in 2006 is the 7500 family. This will make the phone a multimedia platform. One of the more striking functions is the ability to include a VGA video camera at 30f/s in addition to a 3 – 4m pixel still camera. The display will go to 640 X 480. The GUI was equally as compelling:

Perspective windows

Transparent menus;

Photos as texture maps;

Video as texture maps;

Anti-aliased text

Non-intrusive phone status and

Alpha blended transitions.


We just wonder what batteries will power this and how long it will work. George confirmed that battery power is an issue.

1394 over CAT 5 and More

Bill Thompson, President of UStec, made a product pitch. His company supplies products for the home structured wiring market – mostly new homes. The appeal is to use CAT 5 wiring which is present in many homes to transport 1394 with the tecStream components of his company. The CAT 5 wiring would transport both Ethernet and 1394 which is enabled by a stand alone switch at the hub of the network. There would then be point-to-point links to end-point devices which include video camcorders, video deck and televisions. The ability to transport 1394 has an appeal in simplicity but there are drawbacks to this approach:


Video is sent in the clear as an MPEG stream– UStec claims it will support encryption

Links are point to point

Costly - $300 per end node

There is no support for PC HID or USD, thus, Media PC support is only via either Ethernet or IR.

UStec is seeking to make CAT 5 the backbone of a network for which they provide the products. Yet, there are many efforts to accomplish the same but within standards and hopefully lower costs.

There is one positive factor – support for 1394 which is gaining backing across the CE industry. Offline, a number of announcements made at CEDIA EXPO 2004 by CE companies were cited that show continuing support for 1394.

This group includes:

LG Electronics


As we heard earlier from Jack Chaney, Samsung, the CEA is moving ahead on the standardization of 1394. This falls under the efforts of R7. The center piece of these efforts is:

CEA-2027 A User Interface Specification for Home Networks Using Web-based Protocols.

There are a number of important activities at R7 and these include:

Extension of CEA-2027 to allow its use over Ethernet

A standardized way to deliver Electronic Program Guide (EPG) data using Internet Protocols. (See R7 WG 8 - Open EPG)

CEA-2005: An Adapter to Connect Home Network Clusters, which will enable Ethernet/DLNA devices to communicate with Firewire/Cable-CE MOU devices. (See R7 WG 5 - A/V Network Adapter)

R7 WG 7 - Wireless Technology Assessment – an assessment of wireless technologies for home networking.

The 1394 Trade Association and R7 WG 3 have begun work to revise CEA-851 Versatile Home Network (VHN(R)), a standard for a Firewire-based home network backbone. (See R7 WG 3 – VHN Maintenance)

Another 1394 Approach – Oxford Semiconductor

Oxford Semiconductors, via is spokesperson, Tim Elliott at Display Interfaces, reinforced the pitch that 1394 should be the home networking technology of choice. Some of the points made include:

Room to Room connectivity would be via wireless and UWB was suggested as a means of wireless 1394

The advantages of 1394 include:

Isochronous Mode QoS for HD video

Carry multiple A/V streams

Peer-to-Peer Communications defined for and supported by CE devices

Hot plugging support

DVI and HDMI have disadvantages:

Point to Point and a sink connector necessary for each source device

Uni-directional from source to sink only

Supports only audio or video transfer.

Video transfer should be with YUV not MPEG:

If MPEG an decoder would be required on each device

MPEG is not supported by many devices including DVD and Game Consoles

However, Oxford Semiconductor injects is proprietary solution by advocating a “light codec” to reduce the bandwidth. It is claimed that its technology supports DTCP-5C encryption technology. A pitch was made for its chip called the FW601.

WAVE Comments

At one session we asked the question – Do consumers really want this convergence or is this just marketing? Off line, marketing was conceded to be a major factor. We return to a point made by Alfred Poor in the first presentation – where is the value for consumers? How can the industry get the consumer off of the cycle of buying a television every 4 – 6 years at rock bottom prices? Are we likely to see consumers cheer when they have to buy a converter box to make their NTSC television work in a HD environment? Where is the NAVI of HD? For consumers hardly anything beats free content they can do what they want with on cheap CE – from televisions to VCR’s. Analog is looking better every day.

Unfortunately displays are no longer an isolated component in the home electronics mix. With the excitement of HD comes onerous encryption everywhere. When teams of lawyers cannot reach a conclusion on content protection how can one expect the consumer to enjoy the media experience when any handling of the content outside of viewing is denied? As the industry struggles with these issues no one wants to understand the consumer perspective.

Home networking is not a done deal. As Display Interfaces made clear the network is in the eye of the beholder. Yes, DLNA is seeking the bridge the gap but by every indication 1394, which is the interface of choice for CE, is hardly on the DLNA radar. This is all independent of the efforts to use wireless.

Outside of the home networking arena is the larger cloud of uncertainty of HD, digital television and the transition to “flat.” There remains much confusion on home display technology and its adoption.

0438.3 Broadband Marketing

***Maven Launches Broadband Marketing Consortium

Sept. 27, 2004

Maven Networks, Inc., developers of a platform for marketers to deliver high-impact, interactive video content to the desktops of broadband consumers, has launched the Broadband Marketing Consortium (BMC). The BMC is a collaboration of leading marketers to measure consumer response to the emerging trend of receiving interactive video content over the Web directly from a trusted brand. Maven will work with each participant to develop a branded channel that includes attitudinal and behavioral research components designed to evaluate consumer response to the channel.

The primary focus of the BMC is the measurement of consumer attitude and behavior for each marketer's channel. Between 60 and 70 percent of all findings will be blinded and shared among BMC participants in order to allow each brand to benchmark their metrics against the normative data of the group. An executive summary of the results will be delivered to each BMC member.

Members of the BMC will have access to Maven Metrics, which track consumer activity within the application and provide important behavioral data to understand this new model. Primary quantitative research gathered by OTX and IPSOS-ASI will measure the attitudinal shifts in brand-linked recall, changes in perceived brand imagery, consumer buy-in of the channel delivery approach and purchase intent. In addition, segment-based responses to each marketer's "golden" questions will be collected.

The Maven Channel

Each marketer's channel integrates full-screen, DVD- or Hi-Def-quality video with interactive elements - such as viral applications and ecommerce. Moving beyond rich media advertising, Maven-powered channels allow marketers to establish a presence on consumers' desktops with their logo or brand icon. This experience engages consumers differently than typical short form advertising, and is the next step for marketers who are already leveraging long-form commercials, custom-published video programming, how-to video content, and other forms of branded entertainment.

Specific benefits for BMC members include:

-- Program management: Strategic planning, program coordination, and the optimization of the channel

-- Research: Comprehensive, qualitative analysis of all collected results conducted by OTX Research

-- Risk Management: Members pay a low, fixed per user fee for 150,000 consumers, even if the response is significantly larger.

-- Video Content and Delivery: 60 million minutes of DVD-quality video may be apportioned across all of the consumers who-opt in at bandwidth costs significantly less expensive than streaming fees.

-- Reporting: Through the utilization of Maven Metrics, the BMC will track behavioral metrics such as video viewing time interaction rates, viral send-to-friend rates and more.

-- Additional services: Maven's in-house collaborative services team will help each BMC marketer's agency design and develop custom-tailored applications that meet campaign objectives.

0438.4 Firewall and Spam Protection

***McAfee Offers Enhanced Intrusion Prevention Technology in 2005 Version of McAfee Personal Firewall Plus and Essential New Spam Prevention Features in 2005 Version of McAfee SpamKiller

Sept. 28, 2004

McAfee, Inc. has announced the release of McAfee(R) Personal Firewall Plus 2005, an easy-to-use and install defense that helps protect home users from unsolicited inbound and outbound PC traffic and unauthorized attempts to obtain personal information. The new version, now available on the Company's website, incorporates intrusion prevention technology, which helps to proactively block or contain malicious threats from reaching the consumer.

McAfee also unveiled the latest version of its consumer spam prevention service, McAfee SpamKiller. The new version, also available on the Company's website, includes enhanced spam and scam filters that specifically address phishing scams and malicious spam that can lead to identity theft. McAfee has also implemented a dedicated, global McAfee SpamKiller team to track the latest email scams and distribute updates once a new threat is discovered and analyzed.

Personal Firewall Plus

Proactive armor within McAfee Personal Firewall Plus includes both inbound and outbound threat blocking (not available in some free firewall offerings on the market), as well as intrusion detection capabilities. This detection technology proactively monitors the PC for unusual patterns of behavior to help protect home users against identity thieves and hackers. As new threats such as web dialers and worms continue to target home PCs, consumers need to be more aware than ever of the importance of a firewall.

McAfee Personal Firewall Plus 2005 product highlights include the following:

McAfee SpamKiller uses a multi-layered filtering engine to help keep inboxes clean and free of spam and scams and helps filter out unwanted spam email, thereby increasing the likelihood that users receive only the email that they want in their inboxes. With unsolicited, fraudulent and malicious emails being distributed in record numbers, spam protection is an essential component of a layered security strategy.

One type of email threat that is steadily gaining ground among home users is the "phishing scam," defined as a fraudulent email often disguised as a notification from a respected brand that entices recipients into providing personal or financial information. Some analysts are reporting that nearly two million Americans have given personal information to phishing scams, and over one million more may have fallen victim to phishing scams without realizing it.

Due to the rapid growth and consumer threat risk associated with phishing scams, McAfee will be incorporating new phishing scam scanning and detection, commonly referred to in the industry as "anti-phishing rules," into its regularly published rule set updates. These updates will be automatically released early next month for customers using McAfee SpamKiller and will target certain phishing-specific characteristics. Additionally, McAfee recently joined the Anti-Phishing Working Group (APWG), an industry association focused on eliminating the identity theft and fraud that results from the growing problem of phishing and email spoofing.

For the new release, McAfee also conducted an extensive review of all McAfee SpamKiller filters to ensure that home users receive first-rate filtering technology. The product filters spam using Bayesian technology, which learns from the user what types of emails it should block and allow, helping to ensure that users are receiving the email they want. A new "rescue email" function allows McAfee SpamKiller users to rescue all past emails from any particular sender in one click, saving the user time and effort. This feature also allows the user to add that sender to a "friends list."

The following new McAfee SpamKiller features and enhancements will increase the functionality, ease-of-use and comprehensiveness of this best-of-breed product:

-- Scam Filtering helps prevent phishing scams that can result in identity theft and fraud.

-- Invisible Text & Image Filtering zeroes in on colorless content and telltale code inside image-only or image-heavy emails that spammers use to evade anti-spam content engines.

-- Intentional Misspelling Filter helps stop spam with camouflaged content, e.g., in place of mortgage.

-- Enhanced Self-Learning Bayesian Filtering Engine now automatically scans, identifies and removes most junk mail from the inbox, including messages carrying virus attachments.

-- Personal Filter Editor helps users quickly and easily fine-tune spam traps.

-- Filter Update helps keep inboxes clean and free of spam based on a recent extensive review of all filters.

-- User Interface has a new look and feel and streamlined access.

-- Dedicated Global, Content Team assists users so that they get the mail they want and nothing else.

-- Whitelisting now enables users to immediately "rescue all" blocked messages from the same sender or from a newly added friend.

-- Multiple Email Client Support includes Standard POP3 email clients (Outlook Express, Outlook, Eudora, Netscape, etc.), MAPI (Outlook), and MSN/Hotmail (HTML-based clients).

0438.6 Batteries

***Sony Launches World's First Mercury-Free Silver Oxide Battery

BERLIN, Germany
September 29, 2004

Sony had announced the launch of the world's first(1) mercury-free Silver Oxide battery. Considered one of the most difficult challenges within the industry, the introduction of the battery heralds a revolution for millions of watch owners around the world and a major advance for the environment. As a leader in the watch battery market, Sony has utilized its expertise to develop the new product, overcoming major technical obstacles. The new range of ten mercury-free batteries will be launched from January 2005.

The Role of Mercury in Silver Oxide Batteries

A Silver Oxide battery is a small-sized primary battery using Zinc as the negative electrode (anode), Silver Oxide as the positive electrode (cathode) plus an alkaline electrolyte.

Zinc is the activator in the negative electrode and corrodes in alkaline solution. When this happens, it becomes difficult to maintain the capacity of the unused battery. The zinc corrosion causes electrolysis in the electrolyte resulting in the production of Hydrogen gas, a rise of inner pressure and expansion of the cell (Figure 2). Mercury has been used in the past to suppress the corrosion, despite its harmful effects on the environment.

Innovation for a Cleaner, Healthier World

In order to develop a mercury-free Silver Oxide battery, Sony has introduced three technical innovations to prevent zinc corrosion and the generation of hydrogen gas.

- High quality Zinc alloy powder with improved corrosion resistance

This new Zinc-alloy powder includes an extremely small amount of another metal and by optimizing the mixed ration of fine metal used, corrosion rates have been dramatically reduced, i.e. ten times less compared to conventional material.

- Anti-corrosion agents in anode materials

This additive prevents the generation of Hydrogen gas by blocking gas-generation spots. This leads to reducing the corrosion rate by a half, thus reducing the Hydrogen gas generation dramatically.

- Anti-corrosion technology in collector materials

Suppressing the corrosion of the collector electrode can suppress the corrosion of Zinc, but if not processed properly, causes leakage of the inner electrolyte. Sony's unique anti-corrosion technology adopted from electronic device manufacturing improves processing accuracy and precents liquid leakage. Furthermore, a Sony-unique active cathode material delivers a high hydrogen absorption capacity, eradicating the problem of cell expansion.

As for the patents related to the development of mercury-free silver oxide batteries, applications of 5 patents have already been made in Japan, USA and Europe.

Protecting the Environment

With approximately 400 million Silver Oxide batteries sold every year worldwide and considering the fact that the mercury level of Sony's Silver Oxide batteries is 0.2% of the total content of a battery, introducing mercury-free products will reduce the annual usage of mercury by 320 kg and will clearly have a dramatic impact. By developing an innovative range of cells that are free of mercury, lead, cadmium and a variety of other harmful materials, Sony has demonstrated a long-standing commitment to protect the environment. The latest Silver Oxide batteries break new ground, heralding a technical revolution for millions of watch-users across the globe while exceeding the requirements of the European Parliament and European Environmental Council. Currently, revisions in the battery directives are being made in the European Parliament and European Environmental Council, however it is expected that eliminating mercury from Silver Oxide batteries will be an exception due to the difficulty in realizing it. However, Sony succeeded in reaching the 0% mercury level in Silver Oxide batteries and will continue to pursue the advancement of environmentally-conscious policies through innovative technology, aiming to eliminate mercury from all Silver Oxide battery cells in the near future.

0438.8 Structure Wiring

***L-com Publishes Online Structured Wiring Tutorials

Structured Wiring (sometimes called Premise Wiring) is the cabling and connectors used within buildings to connect data and phone networks. These systems are usually rated using a “Category” such as Category 5E or Category 6. The rating is a directly related performance or capability of the structured wiring system.

L-com has published six one page quick reference sheets designed to help consumers understand common connectivity topics:

--Coax Cabling

Coaxial Cabling is a two conductor closed transmission medium that is often used for the transmission of RF energy. The system offers tight control over electrical impedance. This yields excellent performance at high frequencies and superior EMI control/shielding when compared to other types of copper cabling. Coaxial cabling is commonly found in test environments as well as in broadcast and networking systems.

--Video Cabling

The Video Electronics Standard Association (VESA) was formed in 1989. The main goal of this organization is to establish and support standards that benefit manufacturers of personal computers, workstations and associated hardware and software.

--Premise Wiring

Premise Wiring is the cabling, connectors, and accessories that are used to connect LAN (Local Area Network) and phone equipment within a commercial building. Premise Wiring is standardized, this means that a governing body (in this case ANSI and TIA/EIA) set requirements regarding the minimum performance levels for products used as well as offer design and layout criteria that must be followed. The end result of a standard is that all the manufacturers are “on the same page” with regards to how they make their premise wiring products. Also, all cable installers should follow the same rules making it easier to troubleshoot and expand the wiring in the future.

--Fiber Optic

Where copper cabling uses electricity to transmit signals from one end to another, fiber optics use light pulses to accomplish the same purpose. The fiber cable is made of a transparent glass core surrounded by a mirror like covering called cladding. Light passes through the cable, bouncing off the cladding until it reaches the other end of the fiber channel - this is called total internal reflection.

--Data Cabling

This addresses a U.S. standard set of non-ferrous wire conductor sizes. Typical data wiring is AWG number 24, 26 or 28. The higher the gauge number, the smaller the diameter and the thinner the wire.


In the early 1980s, Digital Equipment Corporation, Intel, and Xerox developed the Ethernet Local Area Networking format. This technology was soon accepted by the IEEE Committee, creating the 802.3 standard. This standard dictates the use of CSMA/CD (Carrier Sense Multiple Access with Collision Detection) as its accessing scheme. Networks use a variety of NICs (Network Interface Cards), hubs, transceivers, converters, repeaters & switches, as well as different types of transmission media for carrying signals.
