ABSTRACT:
The present invention provides a video encoding apparatus including a video processor for performing video processing on input video data, a variable length encoder for performing variable length encoding on the processed (quantized) video data and for supplying the encoded data and a generated bit quantity, a DRAM for storing the encoded data that is output as a bitstream, a bitstream output circuit for computing, based on a value found by subtracting the generated bit quantity from a set bit quantity predetermined in advance, a period taken to read from the DRAM the bitstream and for outputting the bitstream as output video data in the computed period, and an arbiter for controlling the operations of the video processor, the variable length encoder, the DRAM, and the bitstream output circuit.
