ADVERTISEMENT INSERTION INTO MEDIA CONTENT FOR STREAMING

摘要

Methods and systems for advertisement insertion into streaming media content are described. In one method, an advertisement insertion tool receives a first indication of a start time of an advertisement break to be inserted into a stream of slices of media content. The advertisement insertion tool identifies a first slice of the slices that encompasses the start time of the advertisement break. The first slice comprises video frames. The advertisement insertion tool truncates the first slice to contain the video frames up to the start time of the advertisement break. An advertisement can be inserted after the truncated first slice and before a next second slice in the stream.

1. A method comprising:
identifying media content comprising a stream of slices; receiving, by an advertisement insertion tool executing by a processing device, a first indication of a start time of an advertisement break to be inserted into the stream of slices of the media content; identifying, from the stream of slices a first slice that encompasses the start time of the advertisement break; inspecting a container of the first slice to locate key frames, wherein the container comprises metadata information and encoded video frames, wherein the inspecting the container is performed without decoding the encoded video frames; creating a modified slice that contains the encoded video frames up to the start time of the advertisement break and does not contain the encoded video frames after the start time of the advertisement break; and creating a new slice that contains encoded video frames after an end time of the advertisement break, wherein creating the new slice comprises:
locating a preceding key frame prior in time to the end time;decoding the preceding key frame and any intervening video frames between the preceding key frame and a frame at the end time; andcreating, from the decoded frame at the end time, a new key frame for the new slice.
