Layered locally cached content transcoding system
A system for transcoding locally cached content may include a memory configured to store at least a video stream. A controller communicatively coupled to the memory may be configured to determine a video definition format of a requested video stream and compare the requested video stream with a video definition format of a cached version of the requested video stream. A transcoder coupled to the controller may be configured to convert the cached version of the requested video stream to a lower video definition format if the video definition format of the cached version is determined to be higher than the video definition format of the requested video stream. If the video definition format of the requested video stream is same as the video definition format of the cached version, the controller may supply the requested video stream using the cached version stored in the memory without transcoding.
