Supporting Today’s Dolby Atmos Workflows
While emerging standards such as ATSC 3.0 continue to advance and provide improved immersive audio for OTA broadcast, the amount of cinematic and live content produced in Dolby Atmos continues to grow as well reaching consumers via Blu-ray Disc, satellite, cable, and streaming services. The workflow required to create, transport, and deliver that content to viewers at home can be complex, requiring the ability to work with PCM, Dolby ED2, Dolby E, Dolby Digital Plus, and Dolby Digital Plus JOC formats - tasks for which the LA-5291 was purpose-built.
Equally at Home for Contribution and Distribution
The LA-5291 integrates well into remote and OB trucks for encoding multi-channel PCM audio into Dolby Digital Plus, Dolby Digital Plus JOC, or Dolby ED2 for distribution. Further downstream, it can transcode Dolby ED2 and Dolby E directly to Dolby Digital Plus and Dolby Digital Plus JOC, and can encode PCM to Dolby Digital Plus and Dolby Digital Plus JOC for final distribution.
