The DP524 accepts an encoded RS-449 serial datastream with timing information, and automatically selects the appropriate decoding algorithm to recover the original audio and any auxiliary data. Synchronization is derived from either a user-provided external clock or the unit's own internal clock. A complementary encoder unit, the Dolby DP503, is also available, supporting the same algorithms and data rates as the DP524. With its very high audio transparency and low time delay, Dolby AC-2 is ideally suited for professional, industrial, and broadcast applications. Originally conceived as an ultra-efficient multichannel coding system, Dolby Digital was introduced in 1992 to provide digital surround sound in the cinema.
