VTC Hybrid Head End

Vietnam Multimedia Corporation (VTC) has selected TANDBERG Television, part of the Ericsson Group to provide the encoding, multiplexing and modulation for ten high-definition and 32 standard-definition channels that are simultaneously played out over satellite and digital terrestrial networks. VTC combines MPEG-2 SD and MPEG-4 AVC HDTV channels in the same TANDBERG Television Multiplexer Transport Stream and the content is modulated using DVB-S2 for satellite and DVB-T for digital terrestrial television.

VTC is the first pay TV operator in Vietnam that is providing MPEG-4 AVC HDTV. “Because we play out many channels to DTH and DTT at the same time, we needed a flexible headend solution to ensure this is achieved in the most efficient way,” said Le Anh Dung, director of R&D center at VTC, in a statement. Dung said TANDBERG Television has delivered this -- and provides the high picture quality at low bit rates needed for satellite and especially for digital terrestrial television. “VTC is a leading broadcaster and platform operator in Vietnam with an innovative hybrid network solution,” said Dario Choi, vice president and general manager of TANDBERG TelevisionAsia-Pacific. Choi said that the company is delighted to work with them on this important project.

Digital terrestrial television is now established in the market and audiences will appreciate the picture quality VTC can deliver. TANDBERG Television delivers the multimedia technology and expertise that is moving digital video forward. Whether it's advanced compression systems, on-demand or content distribution, the company's solutions are used by the world's leading broadcasters, operators and programmers to deliver new viewer experiences and advertising opportunities.

Back in April TANDBERG Television had announced that its iPlex IPTV video processing platform has been selected by North State Communications for its new IPTV headend. In order to maintain full control of its content North State Communications elected to build a full headend and receive television programming directly from broadcasters for MPEG-4 AVC encoding or transcoding. At launch, the TANDBERG headend will deliver over 250 channels of standard definition (SD) and high definition (HD) programs to North State subscribers. The complete MPEG-4 AVC IPTV solution yields significant bandwidth savings by delivering content at the highest image quality and the lowest possible bit rates.
