摘要： Video signal transmitting system in which digital video signal are divided into groups of predetermined frames. Digital video signals of at least one frame are intraframe coded and then transmitted. Remaining digital video signals are interframe coded with reference to the intraframe coded digital video signals, and intraframe coded digital video signals of a subsequent group of frames and are then transmitted. A motion vector from a predetermined reference frame is detected. Video signals are interframe coded by the motion vector to transmit the video signals. A motion vector from a first frame which is a plurality of frames away from the reference frame is converted to a motion vector for a one frame interval between the reference frame and the first frame. The motion vector is optimized, and is then transmitted.

摘要： An encoder considers a frame representing a picture as comprised of areas. For each area, the encoder decides which of frame-based or field-based orthogonal transformation will be most efficient at reducing spatial redundancy in that area. For each area, the encoder decides which of frame-based or field-based predictive encoding will be most efficient at reducing temporal redundancy in that area. The encoder encodes each area of the picture frame using the most efficient orthogonal transformation technique and using the most efficient predictive encoding technique to produce an encoded signal. A decoder decodes the encoded signal. The encoded signal is recorded on a recording medium, transmitted over a transmission channel, or broadcast.

摘要： Recording unit is operative so that, in the case of carrying out high speed reproduction, switch is switched by high speed reproduction control signal inputted from the external, and a signal read out from the recording unit is inputted to VLD and formatter. High speed reproduction control signal is inputted to recording unit, switch and counter. Recording unit reproduces and outputs predetermined data in accordance with high speed reproduction control signal. At VLD, variable length encoding of MPEG is released, and syntax analysis is carried out. Counter counts the number of frames to be transmitted. Moreover, counter outputs temporal.sub.-- reference in accordance with reproduction speed indicated by high speed reproduction control signal. Header converter rewrites temporal.sub.-- reference in picture header in accordance with temporal.sub.-- reference outputted from counter. From facts as described above, high speed reproduction of moving picture can be made.

摘要： Apparatus for deriving from a motion picture film for transfer to a video recording medium a video signal having increased vertical resolution for display using progressive scanning. In the apparatus, a deriving system derives the video signal from the motion picture film; a flag signal generating circuit generates a flag signal indicating that the video signal is for display using progressive scanning; and a recording system records the video signal and the flag signal in the recording medium. In a method of deriving from an interlaced high-definition video signal an interlaced standard-definition video signal having increased vertical resolution, the interlaced high-definition video signal is converted into a progressive high-definition video signal. The number of pixels in the progressive high-definition video signal is reduced to provide a progressive standard-definition video signal, which is converted into the interlaced standard-definition video signal. An apparatus for reproducing a video signal recorded on a recording medium includes a system for reproducing the video signal from the recording medium, and a circuit for extracting from the reproduced video signal a flag signal indicating a display scanning mode for the video signal. A display apparatus includes a circuit for receiving a flag signal indicating a display scanning mode for the video signal, and for generating a control signal; and a circuit, responsive to the control signal, for displaying the video signal in the display scanning mode.

摘要： In a video signal coding method for generating transmission data, a digital video signal is quantized by a quantization step which is controlled on the basis of significant picture information to be transmitted. The significant picture information is, for example, the quantity of information in a main region and in a sub region, the quantity of picture information to be coded, the picture motion in coded regions, the amount of variations in picture information between regions to be coded, or the components of spatial frequency with respect to regions to be coded. By reason of such control of the quantization step, deterioration of picture quality of the transmission data can be avoided, while the quantity of transmitted data is reduced.
