Abstract
A device for use in a television receiver for constantly recording a received program onto a recording medium such as a hard disk drive where a desired scene or program can be easily searched from recorded picture planes without an increase in circuit scale and costs. A picture plane area of a display is divided into a plurality of small picture plane areas and picture planes divided every predetermined time are displayed as index images in correspondence to the plurality of divided small picture plane areas respectively. When a desired one of the index images is designated, moving image information corresponding to the designated index image is read out from the hard disk drive and is displayed. An offset time of a predetermined amount is given to the index images which were divisionally displayed. The received video signal is compressed so that one field is set to a fixed length and is recorded onto the hard disk. A long time recording mode for the hard disk drive is set by varying a compression ratio or a subsampling interval for the video signal. Status information including information reflecting the long time recording mode is added to the compressed video signal and the resultant video signal is recorded on a block unit basis.
