Controlling playback of recordings

摘要

A method of operating a user device for receiving and recording media content. The method includes receiving a media content stream, and initial timing data, such as EPG data, indicative of the time at which a selected program contained within the media content stream is scheduled to begin. At least a portion of the media content stream containing the selected program is recorded to a memory using the initial timing data to determine the recording start and finish time. Second updated timing data, indicative of the time at which the program began, is also received. A portion of the recorded media content stream is then deleted between the beginning of the recording and the beginning of the program as identified by the second timing data. A corresponding apparatus and appropriate computer program are also provided.

1. A method of operating a set top box to receive and record media content, the method comprising:
receiving at the set top box from a media content source, initial timing data indicative of a scheduled start time and a scheduled end time of a selected program, the selected program contained within a media content stream, the initial timing data formed as metadata from the media content source; after receiving the initial timing data, receiving, at one or more inputs, the media content stream; recording the selected program of the media content stream to a memory using the initial timing data to determine a recording start time and a recording finish time; after recording at least some of the selected program of the media content stream, receiving from an Internet source different from the media content source, second updated timing data indicative of an updated start time of the selected program and indicative of at least one of an updated end time of the selected program and a duration of the selected program; deleting at least a first portion of the recorded media content stream between a beginning of the recording and a beginning of the program identified by the second timing data; and deleting at least a second portion of the recorded media content stream between an end of the program calculated from the second timing data and an end of the recording.
