Abstract

A method of arranging recording area sections of a recording medium in a broadcast receiving system having a random access storage device. In this method, the circular buffer area is placed on the first predetermined position of the recording medium for recording the first broadcast signal in real time while playing back the pre-recorded first broadcast signal, and the video file area is placed on the recording medium The second predetermined position is used for recording the second broadcast signal in a logical file at a predetermined time, and the control information area is placed at a third predetermined position of the recording medium for recording information related to the recorded file.

Description

technical field [0001] The present invention relates to a broadcast receiving system that can simultaneously support delayed viewing of broadcast programs and recording / playback of programs, in particular to a method for arranging recording unit partitions on a recording medium, allowing Time-lapse viewing of broadcast programs. Background technique [0002] Hard disk drives (HDDs) in computer systems are random access. Since HDDs have advantages of low cost, large capacity (compared to other auxiliary memories), and high data transfer rate, HDDs have been used as random access storage devices in broadcast receiving systems. [0003] A broadcast receiving system equipped with random access storage devices allows simultaneous recording / playback of streaming video programs and delayed broadcasting. This feature can be realized by controlling the buffer of HDD input / output video stream. [0004] A method for arranging video streams in a hard disk surface as a recording mediu...
