LA-5300 BROADCAST AUDIO PROCESSOR IN DEPTH

A Complete ATSC 3.0 Audio Solution

The roll out of ATSC 3.0 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 Dolby Digital or Dolby Digital Plus to AC-4, and Dolby AC-4 encoding. The ability to handle up to four programs means a single LA-5300 can provide unique encoded streams for 5.1-channel main program audio, SAP, and video descriptive services – all in a single 1RU solution.

I/O for Any Facility

The LA-5300 comes standard with 4 pairs of AES-3 I/O, dual 3G SDI I/O, and AES67 I/O to support SMPTE ST 2110-30 and -31 workflows. Options include Quad-link 3G SDI for facilities utilizing 4K workflows or MADI I/O. Two Gigabit Ethernet ports are provided, one for AES67, and one for remote control via the web-based GUI.

Ready for Today, Ready for Tomorrow

The LA-5300 meets the immediate requirements for ATSC 3.0 audio right out of the box, with channel-based AC-4 encoding, loudness control, and upmixing for multiple programs. As ATSC 3.0 adoption grows, support for its additional features and benefits such as immersive and object-based audio, interactive consumer control, personalized audio, and multiple presentations within a single stream will be incorporated into the LA-5300 via software updates.
