TANDBERG TV, Broadcom Demo Live End-to-End HD MPEG-4 AVC

Deliver Advanced Encoding Delivery System (January 07, 2005)

TANDBERG Television, a leading supplier of open solutions for digital broadcasting and broadband, today announced the worlds first, live demonstration together with Broadcom Corporation, a leading provider of highly integrated semiconductor solutions for broadband communications, of an end-to-end advanced encoding solution supporting high definition (HD) MPEG-4 part 10 (H.264/AVC). This allows broadcast companies to upgrade their networks today with advanced video compression technology.  The two companies will showcase interoperability between Broadcoms set-top box decoder reference platform and TANDBERG Televisions EN5990 video encoder, both the worlds first real-time, decoding and encoding platforms for MPEG-4 part 10. Support for MPEG-4 part 10 allows broadcasters to offer high definition services, which in turn, provides significant cost and business advantages. The demonstration, depicting end-to-end delivery from headend to the set-top box, is taking place this week within Broadcoms booth at International CES, Las Vegas Convention Center, South Hall 4, Booth #35768.

The interoperability between the TANDBERG Television and Broadcom® solutions results in a complete solution that reduces the required bandwidth for HD transmission by up to half when compared against MPEG-2 performance. Most HD channels today use between 12 to 18 Megabytes per second (MB/s) when employing MPEG-2 technology. The integrated TANDBERG/Broadcom solution allows operators to transmit high definition programming at up to half that rate resulting in a substantial capacity change. This type of dramatic bit-rate reduction enables broadcasters with restricted bandwidth architecture to increase their HD channel count using more efficient transmission.

Additionally, TANDBERG Television also supports the advanced profile of VC-1 (the proposed SMPTE standard based on Windows® Media Video 9 for high definition broadcast). TANDBERGs EN5980 is the worlds first real-time, high definition video encoder for Windows Media 9 Series advanced compression.

?The interoperability we can now demonstrate between Broadcom and TANDBERG Televisions products, supporting MPEG-4 part 10, is a breakthrough solution that clearly shows a more economic delivery method for HDTV, explained Roger Bolton, Business Development Director, TANDBERG Television. ?The integration of our technologies will serve as a catalyst for broadcasters worldwide looking to offer high definition services which we can now offer as a turnkey delivery system today. This further proves Broadcoms and TANDBERGs long-term commitment to the MPEG-4 AVC platform.

?This cooperative demonstration between Broadcom and TANDBERG Television represents a significant milestone in the industry for the future delivery of HDTV programs to consumers, said Brian Sprague, Broadcoms Senior Director of Marketing for Set-Top Boxes.  ?The availability of an end-to-end interoperable MPEG-4 AVC solution demonstrates to broadcasters that the equipment is available today to upgrade their networks to this advanced video compression technology, offering them significant cost and business advantages.

The HD MPEG-4 AVC technology incorporates the Broadcom® BCM97395 set-top box decoder reference design platform which includes the companys highly integrated BCM7038 dual channel HDTV and personal video recorder chip and its BCM7411 MPEG-4/AVC video decoder/audio processor chip. The BCM7038 is a dual HD video/audio/graphics and PVR chip that delivers exceptionally high-quality HD programming.  The dual audio and video channels and PVR features offer a number of advanced capabilities such as support for the delivery of HD broadcasting to multiple televisions in the home, separate HD programs with picture-in-picture (PIP), and HD program watch and record PVR capabilities.  The recently announced BCM7411 supports the H.264 video compression standard, which represents the current leading-edge compression technology in the industry.  The chip is designed to improve video compression performance by a factor of two to three times when compared to existing MPEG-2 solutions.  The reference design is targeted for use in cable, satellite, Internet Protocol (IP) set-top box and media center applications.

TANDBERG Televisions EN5990 advanced HD video encoder is a 2RU (rack-unit) encoder that includes a range of advanced broadcast features with MPEG-4 part 10 (H.264/AVC) Main Profile Level 4.0 real-time video encoding. Capable of delivering high-quality HD images with bit-rate reductions of up to 60% on MPEG-2 performance, the EN5990 video encoder produces the best possible pictures from 2.5 Mbit/s to 25 Mbit/s with multiple resolutions and frame rates from 720p24 up to 1080i30. The EN5990 video encoder has been designed to operate in real-time TV delivery environments and guarantees no frame dropping. The key features of this video encoder include extensive video pre-processing for noise reduction and horizontal picture resolution resizing. It also supports ASI (MPEG-2 Transport Stream) output, where MPEG-4 AVC native video content can be carried in an MPEG-2 transport stream alongside other audio and data such as Teletext and closed captioning.
