Abstract

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.

Claims18

Dependent claims

A method to record an event, the method comprising:

starting, by a processor, a recording of the event on a channel according to a recording start time and stop time for the event determined from electronic programming guide (EPG) data;
extracting, by the processor, event scheduling information from a digitally encoded transport stream, wherein the event schedule information includes at least one of a start time and a stop time;
setting, by the processor, at least one of a start bookmark and a stop bookmark in recording metadata for the event based on the event schedule information extracted from the digitally encoded transport stream,
wherein if the start bookmark is set in the recording metadata, the start bookmark setting comprises determining that the recording of the event will be in progress prior to the event scheduling information being extracted from the digitally encoded transport stream, and
wherein if the stop bookmark is set in the recording metadata, the stop bookmark setting comprises determining that the event will be completed prior to the event scheduling information being extracted from the digitally encoded transport stream;
and
trimming or extending, by the processor, the recording of the event based on at least one of the start bookmark and the stop bookmark.

4 more elements

A system for recording of an event, the system comprising:

a processor to:
start a recording of the event on a channel according to a recording start time and stop time for the event according to electronic programming guide (EPG) data;
extract event scheduling information from a digitally encoded transport stream, wherein the event schedule information includes at least one of a start time and a stop time;
set at least one of a start bookmark and a stop bookmark in recording metadata for the event based on the start and stop time from the event schedule information of the event extracted from the digitally encoded transport stream, wherein
setting the start bookmark includes determining that the recording of the event will be in progress prior to the event scheduling information being extracted from the digitally encoded transport stream, and
setting the stop bookmark includes determining that the event will be completed prior to the event scheduling information being extracted from the digitally encoded transport stream;
and
trim the recording based on at least one of the start bookmark and the stop bookmark.

5 more elements

A method to record an event, the method comprising:

setting, by a processor, a recording start time and stop time for the event on a channel according to electronic programming guide (EPG) data;
detecting, by the processor, a new event on a digitally encoded transport stream of the channel;
extracting, by the processor, event scheduling information of the new event from the digitally encoded transport stream, wherein extracting event scheduling information of the new event comprises:
extracting a start time from the event schedule information of the new event;
mapping, by the processor, the new event to the event based on matching event scheduling information of the new event with the EPG data for the event;
updating, by the processor, a recording of the event based upon the event schedule information of the mapped new event, wherein updating the recording of the event comprises setting a start bookmark in recording metadata for the event if the start time of the new event is different from the recording start time for the event according to the EPG data;
and trimming the recording of the event based on the start bookmark.
