Vietnam Television chooses SymNet Edge for ‘new audio backbone’
Published: ASIA
VIETNAM: Eight Symetrix SymNet Edge DSPs have been installed into Vietnam Television (VTV) as part of the broadcaster’s ongoing expansion which will see it add a further two national channels to its existing six. The installation, described as a ‘new audio backbone’ for the broadcaster, was designed and installed by Hanoi-based Symetrix distributor HD Vietnam, though all programming was reportedly done by VTV itself.
VTV is the largest broadcaster in Vietnam, having been in operation for over 40 years. Its current expansion has spurred the creation of a new state-of-the-art infrastructure. However, VTV’s programs are currently broadcasting in multi-channel audio to serve different dialect regions while its program material frequently possesses only two-channel information.
To solve the problem, the broadcaster uses SymNet Edge processing to enable a smooth transition. Whenever program material on channels three and four is absent, the DSP duplicates channels one and two on channels three and four.
Each of the eight SymNet Edge frames has four slots to accommodate different input or output formats. VTV loaded them with an even split of four-channel digital input and four-channel digital output cards. They accept and return digital audio to and from a server and studios via AES. A Dante network connects all of the frames together, effectively pooling all of the inputs, outputs, and DSP resources into a single audio processing hub.
‘A big part of what VTV was looking for in the new system was the ability to route any input to any output,’ explained Nguyen Huyen Dieu, owner of HD Vietnam. ‘They wanted full matrixing and audio processing on all channels.’ In conjunction with the SymNet Edge system, Ross Video audio de-embeders and audio embeders strip and reassociate audio with its respective video stream.
‘VTV is very happy with the capabilities of the SymNet Edge system, and the VTV engineers are also very happy with its ease of use,’ concluded Mr Dieu. The broadcaster is already reportedly planning new HD channels also employ SymNet Edge processing.
