Linear Acoustic debuts StreamStacker-HD
October 5, 2006
Linear Acoustic introduced its StreamStacker-HD high-density audio distribution system at IBC2006.
Consisting of the LA-5173 encoder and LA-5174 decoder, StreamStacker-HD uses advanced multiplexing and coding technologies to deliver multiple channels of PCM and emission rate audio that can be combined with audio metadata and user-definable auxiliary data before being carried via a single AES/EBU-format digital pair.
The LA-5173 encoder accepts up to 16 channels of PCM audio as eight AES pairs or through HD or SD-SDI. Alternately, emission rate audio programs, such as AC-3 or aacPlus, can replace some or all of the PCM channels. The LA-5174 decoder follows the stacked input stream and de-multiplexes and decodes signals to their appropriate outputs. Emission rate programs are output as standard AES-3 signals, re-timed to local plant reference, thereby saving the cost of adding multiple local audio encoders.
