T-VIPS’ pioneering JPEG2000-based solutions for News & Sports Contribution and Distribution

CommunicAsia 2009 - T-VIPS AS, a global leader in professional video management and distribution, with advanced solutions for the contribution & distribution of broadcast quality video signals, today announces that it will be demonstrating its industry leading video transport systems at CommunicAsia. A highlight of the T-VIPS booth (Hall 4/4K1-07) will be demonstrations of its pioneering and award-winning JPEG2000-based contribution and distribution systems. T-VIPS was the first to launch and deploy JPEG2000-based solutions, visitors to its CommunicAsia exhibition booth will see how T-VIPS is expanding its lead in JPEG2000 video transport technology.

“Our JPEG2000-based solutions, which are perfect for the transport of live HD news and sports, are particularly popular right now, with a number of systems in the field throughout the APAC region,” said Johnny Dolvik, CEO, T-VIPS. “We are getting a high level of interest in our systems throughout the APAC region, I think the fact that we can combine high-quality with lowered capex and running costs is increasingly important right now. One of our customers has ‘gone on the record’ stating that our solutions and IP transport have combined to save 70% of his video transport costs, a useful saving in any financial climate!”

T-VIPS will also be showing its CP525 compact multiplexor for advanced traffic multiplexing and regional adaptation, and its CP541 Transport Stream seamless monitoring switch. The CP525’s compact size and innovative design provides a powerful yet cost-effective solution to terrestrial operators and the cable and telecoms industry.

JPEG2000 video transport
The JPEG2000 codec works on both IP and ASI infrastructures and offers a number of additional proven technical advantages over MPEG in News & Sports Contribution and Distribution, as follows:

Video quality - Another advantage with JPEG2000 is that it offers a tool set suitable for high-quality video. Whereas MPEG-2 and MPEG-4 have been designed to deliver a good video quality at low bitrates, the driving force behind JPEG2000 has been to produce a standard with high quality compression of single pictures. MPEG-2 and MPEG-4 are limited to 8-bit video and the 4:2:2 profile, however JPEG2000 can allocate more bits per sample through support for 10 bits video.

Less visual artefacts - An error in an MPEG-2 stream commonly causes blocking effects which last over several frames, this occurs because in MPEG-2 the picture is broken up into small blocks. Bit errors in a JPEG2000 stream create artefacts which are much less visually disturbing than MPEG solutions, as the errors appear as short-lived blurs in the picture.

Intra-frame - JPEG2000 is an intra-frame based encoding scheme. Unlike MPEG-2, MPEG-4 and VC.1, which all encode using P or B -frames, JPEG2000 encodes each frame independently. This is a great advantage for editing, as the video signal may be cut at any place.

Low latency - Reducing latency is crucial for News & Sports TV Contribution. JPEG2000 compression provides much lower latency than for MPEG codecs, as there is no dependency from one picture to the next.

Last mile efficiency - JPEG2000 used in the contribution stage improves the quality of the direct-to-home broadcast by improving the quality of the television source signal entering the distribution encoder. Experience shows last mile MPEG-4 bitrate can be reduced by 15% while maintaining the same video quality.

Sustains multiple compressions - One of the challenges of using MPEG2 compression for contribution purposes is the quality degradation at every compression step. The JPEG2000 compression technology sustains multiple compression steps very well and it is robust to pixel shifts. Insa/PR
