Search giant gives first demo of merged Web, TV system
SAN JOSE, Calif. — Google officially rolled out its GoogleTV initiative at its annual Google I/O conference in San Francisco. The company promised its designs for set-top boxes and related software and services will reshape television by integrating the Web and TV.
Sony will deliver a line of connected TVs and a Blu-ray player integrating Google TV this fall. Logitech is designing a set-top box to bring the features to existing TVs.
All the systems will be powered by Intel Atom-based processors. They mark the first design wins for the PC giant in the digital TV market it has pursued for more than two years. Intel initially partnered with Yahoo to create the Widget Channel interface to bring the Web to the TV.
Google said it will make its GoogleTV software available as open source code in the summer of 2011. It will be available as part of the Android and Google Chrome browser
Google showed ways to use a single search box to find and play current or future content on broadcast TV or the Web. It also showed ways GoogleTV could bring Web services and applications to the TV in ways that create new uses for cellphones and flat-screen TVs.
"It's now possible people may spend more time watching something other than broadcast TV on their televisions," said Eric Schmidt, chief executive of Google who chaired an on-stage panel with the CEOs of Intel, Sony, Adobe, best Buy and other partners.
"We need help from the entire TV ecosystem," said a GoogleTV manager. "For a developer there is no bigger market than the TV market," he added, noting there are an estimated four billion TVs in use, more than the number of cellphones.
GoogleTV relies on Wi-Fi and Ethernet links. GoogleTV set-tops will link via HDMI to any existing cable or satellite set-top box. The software requires graphics processor for on-screen display, a DSP for high def audio and surround sound. Universal remotes are in the works that will include a keyboard and a pointing device to navigate Web pages.
Google showed Android smartphones used as remote controllers for GoogleTV. They could also push online videos to a TV screen. The company also demonstrated Android speech recognition services in the works that let a user issue a voice command to find and tune into a TV show.
Word emerged about GoogleTV in March. At that time a Yahoo spokesman said about its Widget Channel effort that "there will be millions of TVs in the market using our software by the end of 2010," the Yahoo spokesman said.
Demonstrators struggled to get a system up and running on stage, in part, they said because the demo used Bluetooth. Attendees at the event with cellphones on deprived demonstrators of the bandwidth they needed to control on-stage large screen TVs.
Others computer and Web giants have tried and to enable connected TVs with marginal results so far. Microsoft has worked for years to establish its Media Center interface for TVs. Apple has been selling its AppleTV device for more than a year. Neither product has gained much traction, and Apple continues tom refer to AppleTV as "a hobby." Rick Merritt

HDMI's Lip Sync and audio-video synchronization for broadcast and home video
Lip sync correction features take into account processing delays, so that both signals can be synchronized.
By Joseph L. Lias
President, Simplay Labs, LLC
When entertainment content is decoded and rendered on Consumer Electronic (CE) devices, the timing of rendering the video portion of the signal may deviate from the timing of rendering the audio signal. The resultant timing differential is often referred to as a "lip sync" error, since it is most obviously apparent to a viewer when the content contains a representation of a person speaking. In a digital television, the video processing usually takes more time than the audio processing. Because of this, synchronization of video and audio can become an issue, creating an effect similar to a badly dubbed movie, where the audio and video don't match up and the sound of the spoken words is no longer in "sync" with the speaker's lip movement.
HDMI version 1.3 includes a Lip Sync feature that allows the audio processing times in devices to be adjusted automatically to compensate for errors in audio/video timing. The initial implementations of this functionality will be in A/V receivers, but it is likely to appear in DVD players and many other CE devices in the future. Reports from manufacturers indicate that this function is very popular and will be widely implemented.
The HDMI standard requires manufacturers to disclose specific HDMI features enabled in a product. The idea is to provide consumers with the necessary descriptive information they need to understand enabled features that exploit certain capabilities of HDMI, such as Lip Sync. For each feature, the guidelines specify a minimum level of functionality that must be met by the device in order to use the terminology.
While HDMI LLC Authorized Testing Centers (HDMI-ATCs) test for electrical parametric and protocol compliance against the HDMI specification, there is a need to build upon this basic interface testing with additional performance testing programs designed to simplify consumer purchase decisions and enhance the high definition entertainment experience. There are no HDMI-ATC system level Lip Sync performance compliance specifications, or test tools designed to ensure accurate Lip Sync delivery. There is no "timing conformance" specification that must be demonstrated to any authority in order to build a compliant product.
There is an increasing awareness in both broadcast engineering and the CE industry that audio-video synchronization errors, usually seen as problems with lip sync, are occurring more frequently and often with greater magnitude. With the advent of digital processing in CE devices, the issue has become critical. Some CE manufacturers deny there is a problem, believing the audio/video asynchronies in their units to be imperceptible. Knowing how to measure audio/video delays and compensate for them is become increasingly important.
Is it important?
Lip Sync is very important to consumers and the display industry since newer technologies have created a noticeable delay between the processing of video signals and the processing of audio signals. Lip sync correction features take into account processing delays, so that both signals can be synchronized and presented to the viewer together. This greatly improves the entertainment for the viewer.
Lip sync errors detract from the consumer entertainment experience. The lack of lip sync correction is of particular concern in certain types of content, such as product commercials and political candidates' statements. See the report "Effects of Audio Asynchrony on Viewer's Memory, Evaluation of Content and Detection Ability" by Reeves and Voelker for more information (a non-copyrighted PDF is available at Pixel Instruments).
Human studies conducted for sensitivity to audio/video asynchronies have shown that a drift where the audio arrives late is not as annoying as when the audio arrives early. In fact, even a few frames of early audio can quickly be detected by the viewer. The characterization of sensitivity to the alignment of sound and picture includes early work at Bell Laboratories. The extent to which a consumer can tolerate these asynchronies is dependent upon human perceptual limits as well as personal taste. Steinmentz and Engler conducted user studies (R. Steinmentz and C. Engler, "Human Perception of Media Synchronization," Technical Report 43.9310, IBM European Networking Center, Heidelberg.), and they report several figures of merit for quantifying tolerable audio/video asynchrony limits.
In 1998, ITU-R published BT.1359, recommending the relative timing of sound and vision for broadcasting. Studies by the ITU and the others have suggested that thresholds of timing for viewer detection are about +45ms to -125ms, and the thresholds of acceptability are about +90ms to -185ms. In addition, the ATSC Implementation Subcommittee IS-191 has found that under all operational situations, the sound program should never lead the video program by more than 15ms and should never lag the video program by more than 45ms ±15ms.
When viewers encounter difficulties such as lip sync errors, blocking or black screens, they turn to another channel. Therefore, it is imperative that television engineers find and fix network, encoding, and transmission problems before their viewers become aware of them.

DVI and HDMI 2008: A Time of Transition
http://www.instat.com/abstract.asp?id=161&SKU=IN0804099MI
Digital visual interface (DVI) and sister technology high-definition multimedia interface (HDMI) are both high-bandwidth digital interface specifications. DVI-enabled shipments will peak at 117 million in both 2007 and 2008, but should decline thereafter due to the entry of the DisplayPort in the PC and PC peripheral segment.
HDMI was immediately successful upon its 2003 introduction, driven primarily by the CE segment. There were HDMI ports in the vast majority of digital televisions, DVD players and recorders, and A/V receivers shipped in 2007. A smaller HDMI port is leading to increased penetration of portable devices, such as digital camcorders and digital still cameras.
This report contains analysis and five-year annual worldwide forecasts for the penetration of DVI and HDMI into 22 different applications in PCs, PC peripherals, CE, and communications devices. Five-year average selling price forecasts for discrete DVI and HDMI transmitters and receivers are provided. Past history of penetration forecasts back to 2006 is also included, in addition to brief profiles of major DVI and HDMI silicon and IP suppliers. Survey data on HDMI familiarity and use from consumers in the US , UK , Germany , France , Japan , and Korea is also included.
1394 2008: Is FireWire Still Burning?
http://www.instat.com/abstract.asp?id=161&SKU=IN0804096MI
IEEE 1394 (1394) is a high-speed serial bus found in PCs, PC peripherals, and consumer electronics (CE) devices. The technology is facing significant challenges in 2008. 1394 suffers from being the second choice technology in many product segments. 1394 market share in the PC market is shrinking, and is dwarfed by high-speed USB’s 100% penetration. This has helped high-speed USB to become the interface of choice for PC peripherals such as printers, scanners, and external hard disk drives.
In the CE segment, 1394 is being surpassed by HDMI as the digital interface of choice in digital televisions, set-top boxes, and DVD players. Even in markets where 1394 was very strong, such as digital camcorders, it is being challenged by high-speed USB. In the automotive segment, 1394 has been slow to market, and MOST is the dominant auto networking interface. In the industrial segment 1394 is found primarily in security and machine vision cameras.
This report contains analysis and five-year forecasts for all 1394-enabled products, breaking out each PC, PC peripheral, CE, automotive, or industrial application by penetration of 1394a and 1394b for each forecast year. Analysis is provided for all types of 1394, including 1394c and 1394 over Coax. Brief profiles of major 1394 silicon and IP suppliers are also provided.

HDMI Continues To Grow, While DVI Slides
The rapid rise of HDMI and the slow decline of DVI continued in 2008, reports In-Stat (http://www.in-stat.com). The primary driver of HDMI's success is the CE segment, with HDMI ports being found on 95% of the digital televisions (DTV) shipped worldwide in 2008, the greatest volume for HDMI in any product, the high-tech market research firm says. The vast majority of DVI shipments occurred in PC and PC peripheral markets. Digital visual interface (DVI) and high-definition multimedia interface (HDMI), are related, high-bandwidth, unidirectional, uncompressed digital interface standards.
"HDMI is beginning to take off in mobile PCs as an interface that can operate in the PC or CE cluster," says Brian O'Rourke, In-Stat analyst. "In the near future, the interesting CE products to watch will be portable electronic devices, including camcorders, digital still cameras, and portable media players (PMPs). The interest of those products' vendors is being piqued by the introduction of smaller HDMI connectors."Recent research by In-Stat found the following:
- DVI-enabled product shipments will decline at an annual rate of 30% through 2012.
- HDMI-enabled product shipments will increase at an annual rate of 23% over the same period..
The research, "DVI and HDMI 2008: A Time of Transition" (#IN0804099MI), covers the worldwide market for digital visual interface(DVI) and high-definition multimedia interface (HDMI). It provides worldwide forecasts for DVI-and-HDMI-enabled product shipments and market segment penetration through 2012. It also includes analysis of how DVI and HDMI fit into the overall market for interface technologies.

LG Display said to be top LCD panel maker in September
Siu Han, Taipei; Yvonne Yu, DIGITIMES [Tuesday 28 October 2008]Taking advantage of a weak Korean won and the LG Group's vertically integrated supply chain, LG Display shipped 9 million large-size panels in September, taking the top spot among LCD panel makers worldwide, according to market sources.
Total global large-size LCD panel shipments reached 40.2 units in September, up 3.5% sequentially and up 8.4% on year, according to market sources. LG Display ranked number one with a 22% share of total shipments, with Samsung Electronics accounting for 21.6%. Taiwan makers AU Optronics (AUO) and Chi Mei Optoelectronics (CMO) had a 17% and 16% share, respectively.
Global LCD TV panel shipments increased 6.8% compared to August, while LCD panel shipments for monitors and notebooks increased by 1.8% and 3.6%, respectively.
Taiwan-based panel maker AUO indicated that its current market order visibility is low, and the panel maker estimates that its shipments for large-size panels will drop 5-8% in the fourth quarter.

C5 Rating for $1,300 HDMI Cable, Made from Silver
C5 Rating for $1,300 HDMI Cable
PL-HDM2 has pure silver conductors and retails for $1,300. Cool carrying case (included) is not silver.
10.17.2008 — Ethereal Home Theater has submitted its Platinum Series PL-HDM2 HDMI cable to DPL Labs for certification, hoping it will become the first to earn a "C5" rating for a cable measuring 2 feet in length.
In DPL parlance, that means a Class C, Level 5, where "C" is the fastest class of clock rates, and "5" represents the maximum throughput on the DPL scale.
So far, only one cable – in the Honeywell White Series -- has garnered a C5 rating, but that is only for a 0.5 meter product.
Ethereal product manager Brent McCall says that, in the Platinum Series, the company set out to find "just how good a cable could be."
The cables have conductors made of pure silver, says McCall. "There is no copper."
He explains that silver passes higher frequencies better than copper.
Prepared for the onslaught of 1440p resolutions, the HDM2 has braided shield, double-sided copper foil/Mylar shield, and two single-sided shields. The thick cable measures a hefty 23 AWG.
Silver doesn't come cheap, though. The 2-meter cable retails for $1,300.

Silicon Image’s InstaPort promises sub second HDMI switching
Silicon Image’s InstaPort promises sub second HDMI switching
If you have multiple HDMI sources connected to a pre-pro, switcher or TV display, have you ever noticed the rather irritating lag time during switching? I do, I have a desktopdisplay that take about 10 seconds then display a failed HDCP authentication message (it works nevertheless) on the screen every time I turn the TV on. On my Home Theater setup, I have five HDMI sources connected to a Preamp processor. The lag time varies from 3 to 5 seconds, better than the LCD display but could definitely improve with the InstaPort from Silicon Image.
With Silicon Image’s InstaPort technology, HDMI access time can be further accelerated and shaved the lag time down to less than a second! The company explains the InstaPort authenticate HDCP process instantaneously and simultaneously when the devices are connected, not when the input is selected.
The company also says InstaPort be featured in Samsung’s next generation TVdisplays and is currently under evaluation at nine of the top ten HDTV manufacturers for next year’s models.

The High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART,component video, D-Terminal, and VGA. HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers, video game consoles, and AV receivers to compatible digital audio devices, computer monitors, and digital televisions.
HDMI supports, on a single cable, any TV or PC video format including standard, enhanced, and high-definition video along with up to 8 channels of digital audio.[1] It is independent of the various digital television standards such as ATSC and DVB as these are encapsulations of compressed MPEG video streams (which can be decoded and output as uncompressed video stream on HDMI).
HDMI products started shipping in autumn 2003 and currently over 800 CE and PC companies have adopted the HDMI specification (HDMI Adopters).[2][3][4] HDMI began to appear on consumer HDTVcamcorders and digital still cameras in 2006.[5][6][7][8][9] Shipments of HDMI are expected to exceed that of Digital Visual Interface (DVI) in 2008, driven primarily by the Consumer Electronics (CE) Market.[10][11]
