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.
