VIETNAM TELEVISION (VTV) INSTALLS EIGHT SYMETRIX SYMNET EDGE DANTE AUDIO DSPs

SEATTLE, WASHINGTON: Vietnam Television, or VTV, is the largest broadcaster in Vietnam and has been in operation for over forty years. With six nationwide broadcast channels currently in operation and two more under development, VTV is building a state-of-the-art infrastructure. Recently, HD Vietnam, the Symetrix distributor located in Hanoi, supplied VTV with eight SymNet Edge DSPs. HD Vietnam designed and installed this new audio backbone, and their customer, VTV, programmed the system without additional assistance – a testament to SymNet’s ease of use.

Each of the eight SymNet Edge frames has four slots to accommodate different input or output formats. VTV loaded them up 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. The Dante network connects all of the frames together, effectively pooling all of the inputs, outputs, and DSP resources into one massive 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 re-associate audio with its respective video stream.

“The SymNet Edge is a unique processing system,” said Dieu. “It is very powerful and flexible, yet easy to program. Symetrix has proven its reliability in the Vietnamese broadcast industry through its long line of broadcast processors.” Because VTV’s programs are currently broadcasting in multi-channel audio to serve different dialect regions and because program material frequently possesses only two-channel information, VTV uses the SymNet Edge processing to enable a smooth transition. Whenever program material on channels three and four is absent, the SymNet Edge processor duplicates channels one and two on channels three and four.

“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,” said Dieu. The national broadcaster is already planning new HD channels that will employ SymNet Edge processing. If VTV grows beyond its current I/O count or DSP resources, it will be a simple matter to add input/output or more Edge frames and to connect them seamlessly to the existing system via the Dante network.
