TANDBERG Television, part of the Ericsson Group, is showcasing its iPlex UltraCompression IPTV video processing platform and debuting new high performance integrated transcoding capabilities. The new iPlex UltraCompression transcoder supports multi-format MPEG-2 and MPEG-4 AVC SD and HD input streams and uses TANDBERG Television’s next generation AVC platform to transcode them to either MPEG-4 AVC SD or HD output.
Up to 4 UltraCompression transcoders are supported in the 1RU iPlex video processing platform. TANDBERG Television said its iPlex video processing platform ensures the integrity of metadata in the transport streams (closed captioning, teletext etc.) and maximizes the performance of lip sync issues with subtitles. Additionally, when used in conjunction with bulk descrambling receivers, the iPlex transcoding architecture reduces the cost of the overall head-end design and improves video quality. It converts an incoming HD or SD MPEG-2 transport stream to digital baseband, avoiding the composite video interconnection common in multi-box approaches, performs pre-processing for picture and compression optimization, and then encodes the stream into MPEG-4 AVC on a single submodule. The integrated design allows for increased signal processing control, in turn significantly increasing the compression performance. Also, ancillary data such as Teletext and Closed Captions is left intact, allowing the solution to conform with country-specific requirements.
