Abstract

A system (and a method) for compressing reference frames in a video transcoder. A transcoder receives a compressed input stream in a first compressed format and output a compressed output stream in a second compressed format. A decoder and an encoder in the transcoder use compressed reference frames. The reference frames are compressed by transforming a block of pixels from a spatial domain to a frequency domain to generate a coefficient array. The coefficient array is quantized and encoded to compress the size of the coefficients array to the size of a fixed bucket. The values of the entropy coded and quantized array are stored in a memory for use in decoding and/or encoding.
