description	The invention presents a method of providing a modified manifest to a video client for streaming a video sequence associated with the manifest. An original manifest is modified to replace references to locations of lower quality, or bitrate, segments with references to equivalent segments at a higher quality, or bit rate, if the higher quality segment is cached locally. Then, when the video client determines that a given quality of segment should be streamed, it uses the modified manifest to retrieve the appropriate reference for that segment, and if a replacement has taken place, will be provided with the reference to the replacement segment at the higher quality. Thus, the client will always be provided with the highest possible quality segment taking into account local caching.
