LA-5300 Broadcast Audio Processor


The roll-out of ATSC 3.0 - better known to consumers as NEXTGEN TV - brings with it a unique set of requirements, challenges, and opportunities for television broadcasters. The Linear Acoustic LA-5300 provides a single solution for loudness control, upmixing, decoding AC-4 for audience measurement watermark insertion, bitstream analysis, and monitoring, transcoding of Dolby Digital and Dolby Digital Plus to AC-4, and Dolby AC-4 encoding. The ability to handle up to 4 programs means one LA-5300 can provide unique encoded streams for the main program audio, SAP, and video descriptive services—all in a single 1RU solution. A decode and monitor-only version is also available which omits upmixing, watermarking, and AC-4 encoding.
