A Complete ATSC 3.0/NEXTGEN TV Audio Solution
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.
I/O for Any Facility
The LA-5300 comes standard with 5 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 NEXTGEN TV/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.
