    Abstract: A video transmitter comprising a plurality of encoders may be operable to determine, for a transport stream, a constant overall number of bits per time interval corresponding to a frame in the transport stream. For each time interval corresponding to a start and an end of encoding of each of frames using each of the encoders, the video transmitter may allocate a target number of bits to each of the frames to achieve the constant overall number of bits. The allocation of the target number of bits may be based on frame types of the frames and CODEC types of the encoders, where the allocated target number of bits for each of the frames meets buffer overflow/underflow requirements associated with each of the encoders. A quantization parameter (QP) may be calculated and adjusted at each of one or more layers for generating an actual number of bits during encoding.

    Abstract: 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.
