Abstract

An object is to provide a video recording/playing apparatus for facilitating recording/playing of motion pictures. The configuration is provided with, at least, a video input device for inputting analog motion pictures (video), a video capture device for digitizing the motion pictures inputted through the video input device and recording the digitized motion pictures and, at the same time, for converting the motion pictures inputted through the video input device into compressed motion pictures capable of being played in a high compression ratio and in a high picture quality and recording the compressed motion pictures, an information extracting device for extracting arbitrary information from the non-compressed motion pictures captured by the video capture device, a correspondence information generating device for associating the information extracted by the information extracting device with the compressed motion pictures captured by the video capture device, an input device for designating a result of the correspondence, and a compressed video playing device for playing the compressed motion pictures.

Claims26

Dependent claims

A video capture device for processing a video input signal comprising:

a video input circuit adapted to receive a video input signal and to output odd-numbered field signals and even-numbered field signals of an interlace signal;
a color format register adapted to store color format data;
a color processing unit adapted to carry out data processing of said odd-numbered field signals and said even-numbered field signals of said interlace signal;
and
a transfer control circuit adapted to transfer said odd-numbered field signals and said even-numbered field signals to external devices,
wherein an odd-numbered field color format data and an even-numbered field color format data, those are held in said color format register, may be different color format data values,
wherein said color processing unit is adapted to output said odd-numbered field signals the color format of which is specified by said odd-numbered field color format data held in said color format register and said even-numbered field signals the color format of which is specified by said even-numbered field color format data held in said color format register;
wherein said transfer control circuit is adapted to transfer said odd-numbered field signals of said color format which is specified by said odd-numbered field color format data to one of said external devices that is specified by a first transfer destination address supplied to said video capture device and transfer said even-numbered field signals of said color format which are specified by said even-numbered field color format data to another of said external devices that is specified by a second transfer destination address supplied to said video capture device;
and
wherein said first transfer destination address and said second transfer destination address may be different address values.
