  • Patent number: 6256449
    Abstract: In an image encoder and an image decoder of an image transmission system, enabling the deterioration of decoded images in image quality to be avoided, the color frame information DCF in separating a predetermined video signal into a luminance component and a color component (chroma component) is extracted prior to the compressive encoding processing of a video signal SSDI1, added after the compressive encoding processing and delivered to transmission means 18A, and moreover the color frame information is extracted prior to the decoding processing of the compressed video signal SSDDI1 obtained from the transmission means 18A and is added after the decoding processing, thereby enabling data on color frame information DCF to be added to the decoded video signal SSDI1 after the decoding processing as they remain invariant free from deformation (loss) and delivered to the transmission means.

  • Patent number: 5917988
    Abstract: Reproduction instruction and inherent address information from a control unit 3 are sent to drive units 1, 2. Thus, compressed video signals every groups of pictures to which inherent address information are respectively added are outputted from the drive units 1, 2. They are edited after undergone switching at a switch circuit 4. The edited compressed video signals are transmitted to a decoding unit 5. This decoding unit 5 detects, by using inherent address information, the editing point of the video signals which have been edited after undergone switching to carry out decoding processing thereof to output a video signal, thereby making it possible to obtain a video signal of satisfactory picture quality without outputting noise at the editing point.
