BROADCAST SCHEDULE SYNCHRONIZED DIGITAL VIDEO RECORDER

摘要

A disclosed example may accurately start and stop a recording of an event based on accurate event scheduling information from a channel broadcaster. A start time and stop time for a recording of the event may be scheduled according to EPG data. In response to determining that the channel is a controlled channel, which includes accurate event scheduling information provided by a channel broadcaster, a recording may be initially scheduled for the event according to the EPG data with an extended duration of a predetermined time value. The digitally encoded transport stream may be continuously monitored to detect a new event and the detected new event may then be mapped to the event. As a result, the recording time of the event may be accurately updated by extracting a set of parameters from the accurate event schedule information of the new event.

主权项

1. A method to facilitate a recording of an event, the method comprising:
receiving, by a controller of a video recording server, a record request from an end-user for the event on a channel; setting a recording start time and stop time for the event according to electronic programming guide (EPG) data; determining whether the channel is included in a controlled channels log, wherein the controlled channels log comprises event scheduling information from a digitally encoded transport stream; and in response to determining that the channel is in the controlled channels log,
scheduling the recording for the event according to the EPG data with an extended duration of a predetermined time value,detecting a new event on the digitally encoded transport stream of the channel in the controlled channel log,mapping the new event to the event, wherein mapping the new event to the event includes:determining, from the event schedule information of the new event, whether the new event has a start time within a predetermined tolerance to the recording start time for the event according to the EPG data;determining whether the new event has a same title as a title of the event according to the EPG data; andlinking the new event to the event in response to determining that the new event has the same title as the title of the event according to the EPG data, andupdating the recording of the event, wherein the updating comprises extracting a set of parameters from the event schedule information of the new event.
