BROADCAST PROGRAM RECORDING OVERRUN AND UNDERRUN SCHEDULING SYSTEM

摘要

The start and end times of a broadcast program's recording schedule that has a predetermined start and end broadcast time can be adjusted. An on screen program guide (1101) is displayed to the viewer and lists the predetermined scheduled broadcast times (1102) and channels of a plurality of programs (1103). The viewer selects a particular broadcast program (1105) to record from the program guide. The program's information such as program identifier, start and end times (1104, 1105) and storage duration are inserted into a recording schedule database. The viewer can adjust the scheduled start and/or end recording (1104, 1105) times for a program (1103) by specifying the time increment (1403) to add or substract from the start and/or end recording times (1104, 1105) of a specific program (1103) or series of programs even during the recording. The recording schedule is adjusted to the viewer's modifications. Programs are recorded, when the recording schedule indicates that it is time to do so. The viewer can randomly access the recorded programs for play back.
