The Design of a Video Friendly Audio Coding System for Distribution Applications
Louis D. Fielder, Craig C. Todd · 1999
Dolby E is an audio bit-rate reduction system for audio-visual distribution applications. The coding system was developed for situations involving tandem coding operations, editing and switching at video frame boundaries, and transport on AES3 serial-digital data paths. Special TDAC transforms are organized on a frame structure that allows for adaptive transform lengths and frame synchrony with video framing. Sample rate conversion allows for a variety of video formats to be accommodated.
