Title: Video transmission apparatus employing intra-frame-only video compression that is mpeg-2 compatible
Inventor: KIM YONG JE
IPC: H04N7/26
Filed: 1998-08-12
Abstract: PURPOSE: A video transmission apparatus employing intra-frame-only video compression that is MPEG-2 compatible is provided to generate consecutive I frames according to the MPEG-2 standard, but in a departure from the MPEG-2 standard without intervening P or B frames CONSTITUTION: Intraframe-only video compression encoding of every successive video frame is done the way intraframe video compression encoding is done on I anchor frames in MPEG-2, and each frame is identified as being intraframe video compression encoded similarly to the way it is done on I anchor frames in MPEG-2. The encoder for doing this is simpler than that for coding P frames and B frames as well as I frames, since there is no need for motion estimation circuitry. Using such an encoder in a digital camcorder reduces power drain on the battery and permits the weight and size of the camcorder to be reduced. Intraframe-only video compression facilitates editing video. In many systems in which video editing is done an MPEG-2 decoder is already available, so there is no additional cost for a decoder to decode the transport stream of I frames without intervening P or B frames. If an MPEG-2 decoder is not already available in a system, providing such a decoder is reasonable in cost, since the amount of hardware in an MPEG-2 decoder is considerably less than that in an MPEG-2 encoder.
