Extended W3C media extensions for processing DASH and CMAF inband events

An apparatus for processing events in a media stream, the apparatus comprising:

• at least one memory configured to store computer program code;
• at least one processor configured to access the computer program code and operate as instructed by the computer program code, the computer program code including:
• first obtaining code configured to cause the at least one processor to obtain a first event processing buffer and a second event processing buffer, wherein the first event processing buffer comprises an event start offset for each of a one or more event segments, and wherein the second event processing buffer comprises event dispatch information for the each of the one or more event segments;
• second obtaining code configured to cause the at least one processor to obtain one or more new event segments associated with media data;
• first spitting code configured to cause the at least one processor to split the one or more event segments in the first event processing buffer and the second event processing buffer based on event duration of the one or more new event segments;
• first overwriting code configured to cause the at least one processor to overwrite the one or more event segments in the first event processing buffer and the second event processing buffer based on the event duration of the one or more new event segments;
• and
• first dispatching code configured to cause the at least one processor to dispatch the one or more event segments and the one or more new event segments based on the first event processing buffer and the event dispatch information in the second event processing buffer.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

• obtaining a first event processing buffer and a second event processing buffer, wherein the first event processing buffer comprises an event start offset for each of a one or more event segments, and wherein the second event processing buffer comprises event dispatch information for the each of the one or more event segments;
• obtaining one or more new event segments associated with media data;
• splitting the one or more event segments in the first event processing buffer and the second event processing buffer based on event duration of the one or more new event segments;
• overwriting the one or more event segments in the first event processing buffer and the second event processing buffer based on the event duration of the one or more new event segments;
• and
• dispatching the one or more event segments and the one or more new event segments based on the first event processing buffer and the event dispatch information in the second event processing buffer.
