METHOD FOR CONTROLLING A COMPRESSED DATA BUFFER

摘要

A system and method for controlling a data encoder buffer is disclosed, including an encoder for encoding input data as a first bit sequence in a bitstream; a processor having a predetermined size for converting the first bit sequence to a sequence having the predetermined size; and a decoder for decoding the modified bit sequence. The modified bit sequence is generated by inserting bits to the first bit sequence. The encoder encodes the input data at a rate such that a final capacity of the data buffer is less than a function of the predetermined size, a desired decoding rate, and an initial capacity of the encoder buffer. The data buffer has a total buffer capacity which is less than a function of the actual rate and the desired decoding rate. In an exemplary embodiment, the capacity of the data buffer is less than one half the capacity of the decoder buffer. A method is also disclosed for controlling a data buffer comprising the steps of receiving input data; encoding the input data using an encoder to generate a first bit sequence; detecting a condition of the first bit sequence having a size of less than a predetermined size; converting the first bit sequence having the less than the predetermined size to a second bit having the predetermined size; receiving the bitstream; and decoding the second bit sequence.
