The DSC standard is a specification of the algorithms used for
|
|
compressing and decompressing image display streams, including
|
|
the specification of the syntax and semantics of the compressed
|
|
video bit stream. DSC is designed for real-time systems with
|
|
real-time compression, transmission, decompression and Display.
