Abstract: A broadcast receiving system which simultaneously supports time-delayed viewing and recording/reproduction. In the broadcast receiving system, blocks are discontinuously arranged in a circular buffer to rapidly implement time-delayed viewing of a channel and recording/reproduction of another channel at the same time. To do so, circular buffer blocks are discontinuously arranged on a disk surface in a time-delayed viewing mode. If the time-delayed viewing mode is performed simultaneously with a recording/reproduction mode, video streams for time-delayed viewing are recorded in free blocks nearest to blocks in which video streams of a channel to be recorded are recorded or from which video streams of a channel to be reproduced are reproduced. Therefore, two or more modes can be performed effectively and simultaneously.
