Dolby® Pro Logic® II
The Dolby® Pro Logic® II is an advanced matrixing technology that delivers convincing, realistic surround sound from stereo content. It delivers five full-range channels (including two surround channels) derived from spatial cues that occur naturally in stereo recordings, soundtracks and broadcasts. The result is a compelling yet entirely natural and realistic surround effect that is incorporated in virtually all home theater products, including audio/video receivers (AVRs) and home-theater-in-a-box (HTIB) systems.
Dolby® Pro Logic® II technology is also used by broadcasters to encode their stereo signals specifically for Pro Logic II playback. This makes it possible for them to deliver specific surround and localisation effects over stereo services that are more like discrete 5.1 transmissions, without compromising regular stereo and mono playback.
The ESPICO implementations are based on the Dolby reference model with proprietary optimisations to reduce memory and MHz requirements. Contact ESPICO for specific resource requirements.
