Tandberg Television Intros TV over IP ProductsCompany shows combined broadband/cable headend and launches TandbergTelevision portal tools at IBC 2001 (September 26, 2001)
"Our broadband products are designed to bring broadcast quality TV, interactive and Video on Demand (VOD) services into the 'triple play' mix. By enabling broadcast quality TV services to be delivered in IP format alongside telephony and high speed internet, TandbergTelevision is working with operators around the world to build broadband cable and DSL networks that deliver the promise of enhanced entertainment," says Jeremy Thorp, CTO of TandbergTelevision.
At IBC 2001, TandbergTelevision showed its combined broadband/cable head-end delivering live broadcast quality programming over IP to both TV screens and personal computers. TandbergTelevision also launched its TandbergPortal Tools software at IBC with applications such as content extraction and Meta data insertion. The tools enable the repurposing of content to meet broadband protocol requirements. For example, to deliver a multi-channel TV service, operators need to be able to have an Electronic Programming Guide to help viewers find what they want to watch. In the broadcast world the program markers of scheduling are called Service Information (SI). In the broadband world this SI needs to be converted to XML format for use on a browser style EPG.
The TandbergTelevision broadband architecture is based on a Content Streaming Headend platform that takes in MPEG-2 video and audio feeds, encodes or descrambles them and then repurposes the content into IP format for multi-casting over the broadband IP network. The system provides a complete digital turnaround solution and can receive, decode, descramble and process transmissions from a digital satellite transponder, digital cable head-end or digital terrestrial transmitter to provide national and regional TV services to consumers on broadband networks.
A number of TandbergTelevision products are included in the broadband system:
* TandbergTelevision's new range of flexible, compact encoders
* The TT7116 IP Streamer, which takes the MPEG-2 stream, consisting of a multiplex of digital TV programs, and splits the stream into single program streams, which are then transmitted as IP Multicast sessions over the broadband network;
* Digital turnaround facilities with features such as Bit-Rate Changing to support the seamless management of incoming multi-channel feeds, to insert local content, apply conditional access and create outgoing multiplexes for transmission across broadband networks;
* Super to Regional headend transmission flexibility over ATM or IP;
* Two-way interactive services with return-path products based on Cisco, Liberate and Pace systems.
"The vast majority of broadcast television content is created in MPEG-2 standard and therefore to be deployed over IP networks, a bridge needs to be created between the broadcast and broadband worlds. That's actually where TandbergTelevision comes into play. Our whole heritage is built on MPEG, we're broadcast TV specialists, and we are bringing our broadcast skills to the broadband world by enabling the conversion of content from MPEG to IP and the management of such content," adds Olav Wendelbo Bungum, Project Director, Broadband of TandbergTelevision.
