Abstract
The invention concerns a test stream generator for generating a compressed video stream for testing a video decoder, the generator including: a context-aware pseudo-random generator (202) adapted to generate pseudo-random values of syntax elements based on decoding context data; a decoding process module (206, 206′) adapted to process the syntax element values and to generate the decoding context data and binarization context data; and a binarizer module (204) adapted to encode the syntax element values based on the binarization context data in order to generate the compressed video stream.
