METHOD AND ARRANGEMENT FOR PROVIDING ADAPTIVE BITRATE-DYNAMIC ADVERTISEMENTS

摘要

A method and arrangement in an advertisement control system for providing adaptive bitrate-dynamic advertisements in an adaptively streamed video stream defined by a manifest. A bitrate monitor monitors the varying delivery bitrate of the video stream. A processor determines whether the delivery bitrate has fallen below a minimum bitrate threshold of a next advertisement in the manifest. If so, the arrangement replaces the next advertisement with a replacement video chunk such as a replacement advertisement having a minimum bitrate threshold lower than or equal to the delivery bitrate of the video stream. The arrangement may be implemented in an advertisement server, a client device, or a manifest creator.

1. A method in an advertisement control system for providing adaptive bitrate-dynamic advertisements in a video stream defined by a manifest, wherein adaptive streaming in a delivery network causes a delivery bitrate of the video stream to vary due to changes in delivery network conditions, the method comprising:
monitoring the delivery bitrate of the video stream in the delivery network; determining whether the delivery bitrate of the video stream has fallen below a minimum bitrate threshold of a next advertisement in the manifest; and when the delivery bitrate of the video stream has fallen below the minimum bitrate threshold of the next advertisement, replacing the next advertisement in the manifest with a replacement video chunk having a minimum bitrate threshold lower than or equal to the delivery bitrate of the video stream.
