Dolby Stereo and Dolby Surround are also known as Dolby MP, Dolby SVA and Pro Logic. Dolby SVA matrix is the original name of the Dolby Stereo 4:2:4 encoding matrix. The term "Dolby Surround" refers to both the encoding and decoding in the home environment, while in the theater it is known "Dolby Stereo", "Dolby Motion Picture matrix" or "Dolby ...
Although Dolby Surround was introduced as an analog format, all Dolby Digital decoders incorporate a digitally implemented Dolby Surround Pro Logic decoder for digital stereo signals that carry matrix-encoded Dolby Surround. One of the first was the MSP400 surround sound receiver and amplifier by RCA for their high-end Dimensia brand.
Dolby released Dolby Pulse decoders and encoders in September 2008. HE-AAC v2 is the core of Dolby Pulse so files and streams encoded in Dolby Pulse will playback on AAC, HE-AAC v1 and v2 decoders. Conversely files and streams encoded in AAC, HE-AAC v1 or v2 will playback on Dolby Pulse decoders.
Dolby reintroduced the Dolby Surround terminology in 2014. The term now refers to a new frequency-domain decoder/upmixer. Dolby Surround is a complete replacement for Pro Logic; it takes in stereo (discrete or matrixed), 5.1 and 7.1 inputs to play over a wide range of output configurations including those with height channels.
