<p>A novel encoding apparatus for encoding an input digital video signal in a compressed form comprises a control unit for counting the number of picture lines in each of the plurality of the video frame data, a switching block for dividing the video frame data into a multiplicity of subframes under the control of the control unit, a multiplicity of FIFO buffers for storing the divided video frame data, a multiplicity of encoders for compressing the video frame data, each of the encoders compressing each of the multiplicity of subframes, and a frame formatter for coupling the compressed video frame data. Further, a novel decoding apparatus for decoding an encoded digital video signal in an encoded bit stream form includes a detector for detecting slice start codes from the encoded digital video signal and generating a slice start detection signal, a control unit for counting the number of the slice start codes in the encoded bit stream and for generating a control signal, a switching block for dividing the video frame data into a multiplicity of subframes, a multiplicity of FIFO buffers for storing the divided video frame data, a multiplicity of decoders for reproducing the original video image signal, each decoder reproducing each of the multiplicity of subframes, a frame formatter for coupling the reproduced original video image signals. <IMAGE></p> |
