Chapter 3: Applications
The LA-5269 is essentially a modern updated version of the classic Dolby DP569. Features
such as dual power supply, HD/SD-SDI I/O, and SNMP have been added to a Dolby-
manufactured encoder card. Support for encoding from PCM inputs is provided along
with several space and cost saving transcode functions that allow inputs to be PCM, Dolby
E, or Dolby Digital (AC-3) and outputs to be Dolby Digital, Dolby Digital Plus, or option-
ally Dolby Pulse.

will not be used in every case.
