Abstract
A method for producing a compressed video bitstream having a plurality of frames from data that specifies a single still image. The still image is encoded into data specifying a single intra (“I”) frame having an amount of data that approaches, but remains less than, storage capacity of a buffer memory included in a decoder. A single copy of the I frame data is then combined in the compressed video bitstream with data for at least one null frame. Decoding of the compressed video bitstream assembled in this way produces frames of decoded video that do not appear to pulse visually.
