ABSTRACT:
Necessary coded data only can be read out at random accessing even with recording medium having coded data recorded thereon but whose code quantity is out of proportion to time. Once a recording medium was loaded into a recorder-player connected with a coded-data control device, the device reads control data from the recording medium and stores the data in a coded data control portion. At random accessing, the control data is read-out from the coded-data control portion and entered into a recording medium controller which in turn controls the recording medium to read-out only desired data according to the information inputted from the coded data control portion. In random access playback, fast playback from the midway of a video-sequence can be realized by accessing coded data of a video frame by using control data.
