  • Patent number: 7286571
    Abstract: The present invention provides systems and methods for providing on-demand datacasting. A system according to an exemplary embodiment of the present invention comprises a rate generator for controlling the rate at which data signals are combined with audio/video signals. The system may also include a system controller for controlling the rate of the rate generator. The system controller may also monitor the complexity of the audio/video signals, calculate an average complexity of the audio/video signals, calculate an average complexity of the audio/video signals and determine whether the average complexity is greater than the typical complexity of audio/video signals. The system controller may adjust the rate of the rate generator based on the determination of whether the average complexity of the audio/video signals is greater than the typical complexity of audio/video signals.

  • Patent number: 5646687
    Abstract: A temporally-pipelined predictive encoder/decoder circuit for encoding or decoding an input signal containing a sequence of data frames received at a particular frame rate and frame data rate into an output signal having an equal frame rate employs a plurality of N predictive encoders/decoders. An input buffer may be used to extract the information for each data frame in the input signal and supply such information to a corresponding one of the encoders/decoders at rate of 1/N of the particular frame data rate. Each encoder/decoder generates corresponding encoded/decoded information as it is received as well as provides digitized frame information to the encoder/decoder processing the next received image frame. The encoded/decoded information is provided to corresponding frame buffers which temporarily store such information.
