Philips Semiconductors, an affiliate of Royal Philips Electronics (NYSE NYSE

: PHG), has unveiled the first Windows Driver Model-based implementations of TV teletext functionality in the Windows Millennium Edition See Windows ME.

(operating system) Windows Millennium Edition - (Windows ME) An update of Microsoft Windows 98, released in 2000. ME included updates of packaged software and new software such as Windows Media Player 7, Windows Movie Maker.
. The ability for PCs with TV receiver cards to use this technology will be included in Microsoft's next generation operating system for home PC users, Windows Millennium Edition, further globalizing and deepening the PC platform's consumer capabilities.

"This represents yet another advancement in the video capabilities of the Windows platform," said Harish Naidu, general manager for digital audio and video at Microsoft Corp. "We're excited to work with Philips Semiconductors to bring teletext capability to millions of our mutual customers worldwide."

"By further enabling the Windows platform's video capabilities, Philips Semiconductors expects to see a surge in demand for its PC video digitizer chipsets, a market which we pioneered in the early 1990s," said Martin Maloney, international product marketing manager, Infotainment Systems, Philips Semiconductors. "We are also the only supplier to provide all key components to the PC video market, including TV tuners, PC video decoders, multimedia PCI (1) (Payment Card Industry) See PCI DSS.

 bridges, stereo decoders, and PC video encoders. Add-on cards for home PC users are the prime target market for this technology."

Teletext is the free, well-established, and broadly supported TV-based data service regularly used by over 30 million households worldwide. Steadily growing in usage since the 1970s, teletext has successfully foreshadowed the massive e-commerce potential of the Internet. Teletext has also provided, and continues to provide, a very useful forerunner in the development of the ATVEF (Advanced Television Enhancement Forum) A consortium of broadcast, cable and computer companies founded in 1998 that developed the ATVEF Enhanced Content Specification, an HTML and JavaScript-based format for adding content to interactive TV.  standard for interactive enhanced television. The Advanced Television Enhancement Forum (ATVEF) is a cross-industry alliance of companies representing the content creators, the broadcasters, the consumer electronics industry, and the PC industry. This alliance of companies has defined protocols for HTML-based enhanced television, which allow content creators, such as major television broadcast networks, to deliver enhanced programming over all forms of TV transport (analog, digital, cable, terrestrial, and satellite) to any intelligent receiver.

The Windows Driver Model In computing, the Windows Driver Model (WDM) — also known (somewhat misleadingly) at one point as the Win32 Driver Model — is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older  implementation is Microsoft's core driver model for future operating systems and, using this approach, the data capabilities of teletext will actually be embedded within the operating system, rather than installed through multiple vendor specific driver and hardware implementations. This provides software developers with a common platform on which to develop a new generation of powerful, low-cost, feature rich video-based multimedia applications using megabytes of broadcast data, including IP over VBI See vertical blanking interval.  (Vertical Blanking Interval The part of a TV signal that is sent between each video frame. In North American TV (NTSC), the vertical blanking interval (VBI) takes up the last 45 lines of each 525-line frame. ). It is thus a major step forward to seamlessly merge multiple analog and digital broadcast streams with the Internet.

The implementation uses Philips Semiconductors' in-house-developed drivers for robust data slicing and WST WST

 (World Standard Teletext) decoding, running on Philips Semiconductors' 9-bit video decoder/scaler SAA (Systems Application Architecture) A set of interfaces designed to cross all IBM platforms from PC to mainframe. Introduced by IBM in 1987, SAA includes the Common User Access (CUA), the Common Programming Interface for Communications (CPI-C) and Common Communications 7114 and multimedia streams controller SAA7146A. Slicing of the teletext data (extracting the binary stream of data from the multi-level complex analog TV signal) is key to system performance.

Besides supporting teletext, Philips Semiconductors' SAA7114 also provides best-in-class video performance, using a 4-line PAL/NTSC adaptive comb filter. Significantly, this chip also digitizes the video stream using a line-locked 27MHz clock, exactly the frequency used by real-time MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs).  encoders and decoders, to enable PC-based time-shift TV viewing. Exploiting such capabilities will be essential as Philips Semiconductors and Microsoft move forward to continue to revolutionize the PC platform with such things as the Broadcast Driver Architecture The Broadcast Driver Architecture (or BDA) is a Microsoft standard for digital video capture on their Windows operating systems. It encompasses the ATSC and DVB standards and gives developers a standardized method of accessing TV tuner devices (usually PCI or USB). .
