Abstract
According to some embodiments, systems, methods, apparatus, and computer program code are provided to process video source data to insert ad or other content into a video stream for distribution to client devices.
Claims14
A method comprising:
- receiving, by a stream processing device, an original content stream generated from an input video source, the original content stream having a plurality of segments each segment having a number of frames, the original content stream received without an advertisement;
- identifying information associated with an advertisement for insertion into the original content stream at a predetermined point in time, the advertisement having a predetermined length and a plurality of segments, each segment having a number of frames;
- updating, for each of the plurality of segments that follow the predetermined point in time of the original content stream, a program clock reference (PCR) of each of the plurality of segments by adding the predetermined length of the advertisement to the PCR of each of the plurality of segments;
- identifying a starting one of the plurality of segments associated with the predetermined point in time of the original content stream and removing any frames of the starting one of the plurality of segments after the predetermined point in time of the original content stream;
- calculating an ending point in time based on the predetermined time of the original content stream and the predetermined length of the advertisement;
- identifying an ending one of the plurality of segments associated with the ending point in time and removing any frames of the ending one of the plurality of segments before the ending point in time;
- and
- inserting the advertisement into the original content stream at the predetermined point in time of the original content stream to produce an updated content stream for delivery to a client device.

A method, comprising:
- receiving, by a stream processing system, an original content stream generated from an input video source, the original content stream having a plurality of segments each having a number of frames and received without an advertisement;
- generating at least a first copy of the original content stream, the at least first copy of the original content stream having a starting point delayed a first amount from a starting point of the original content stream;
- identifying information associated with an advertisement for insertion into the original content stream at a predetermined insertion point in time and having a predetermined length, the advertisement having a plurality of segments each having a number of frames;
- selecting one of the original content stream and the at least first copy of the original content stream as the active content stream;
- identifying a starting one of the plurality of segments of the active content stream associated with the predetermined point in time of the active content stream and removing any frames of the starting one of the plurality of segments after the predetermined insertion point in time of the active content stream;
- calculating an ending point in time based on the predetermined insertion point in time of the active content stream and the predetermined length;
- identifying an ending one of the plurality of segments associated with the ending point in time and removing any frames of the ending one of the plurality of segments before the ending point in time;
- and
- inserting the advertisement into the active content stream at the predetermined insertion point in time to produce an updated content stream for provision to a client device.

A method, comprising:
- receiving, by a processing device, an original content stream generated from an input video source, the original content stream having a plurality of segments each having a number of frames, the original content stream received without an advertisement;
- generating a number of copies of the original content stream, each of the number of copies of the original content stream having a starting point delayed from a starting point of the original content stream, wherein the number of copies of the original content (“S”) is determined based on the formula S=(M/(M−K)) where “M” is the length of each segment and “K” is a target minimum segment size, wherein the target minimum segment size is selected to ensure that no segment that has only a single frame is selected as the active segment;
- identifying an advertisement for insertion into the original content stream at a predetermined insertion point in time associated with the original content stream and having a predetermined length, the advertisement having a plurality of segments each having a number of frames;
- selecting one of (i) the original content stream and (ii) one of the number of copies of the original content stream as the active content stream;
- and
- inserting the advertisement into the active content stream at the predetermined insertion point in time to produce an updated content stream for provision to a client device.
