    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: Various systems and methods are provided for transmission of related data components across independent streams. In one embodiment, among others, a transmitting device may separate transmission data into related data components and transmit each related data component in an associated transport stream. Each related data component includes a synchronization tag associated with synchronization of the related data component within the transmission data. In another embodiment, a receiving device may receive related data components transmitted in separate transport streams and decode the related data components based at least in part upon a synchronization tag included in each related data component. In another embodiment, among others, a method for includes receiving data components transmitted on a plurality of transport streams, separating related data components from unrelated data components in the transport streams based at least in part upon a synchronization tag of each related data component; and decoding the related data components.
