# Introduction

The LA-5300 provides everything broadcasters need to be ready for NEXTGEN TV/ATSC 3.0 audio in a single, compact, integrated package, including:

- Dolby® AC-4 encoding from PCM
- Transcoding from Dolby Digital and Dolby Digital Plus to Dolby AC-4
- Dolby AC-4 decoding for audience measurement watermarking and bitstream analysis and monitoring
- Linear Acoustic UPMAX® ISC upmixing
- Optional Verance and Nielsen watermarking
- Loudness control via Dolby Real-Time Loudness Leveler (when encoding to Dolby AC-4)

Optionally, it also provides processing for a second legacy ATSC 1.0 program, including:

- Dolby® Digital Plus (E-AC-3) and Dolby Digital (AC-3) encoding
- Linear Acoustic UPMAX® ISC upmixing
- Optional Verance and Nielsen watermarking
- Loudness control via Linear Acoustic APTO® or Dolby Real-Time Loudness Leveler

> [!NOTE]
> **Note -** The LA-5300 is also available in a decode and monitor-only version which omits upmixing, watermarking, and AC-4 encoding (which includes loudness control). Accordingly, some menus, screens, and controls will look different from those seen here.
