Abstract
A data stream, such as a video stream, may comprise one or more event trigger messages indicating an upcoming event in the stream. The time (e.g., pre-roll time) between the event trigger message and its corresponding event may be modified, based on rules, to provide a network operator, service provider or downstream recipient more (or less) time to prepare for the event. This may be accomplished by moving the event trigger to an earlier (or later) location in the stream, and/or editing the event trigger to indicate the different pre-roll time.
Claims13
An apparatus comprising:one or more processors;
- andmemory storing instructions that, when executed by the one or more processors, cause the apparatus to:receive video content comprising a first event trigger message that is at a first time in the video content, wherein the first event trigger message indicates an event that starts at a second time in the video content;
- andbased on a time offset between the first time and the second time:remove the first event trigger message;
- and insert a second event trigger message at a different time in the video content.
A non-transitory computer-readable medium storing instructions that, when executed, cause performance of actions comprising:receiving video content comprising a first event trigger message that is at a first time in the video content, wherein the first event trigger message indicates an event that starts at a second time in the video content;based on a time offset between the first time and the second time:removing the first event trigger message;
- andinserting a second event trigger message to a different time in the video content.
