Abstract
Dynamic rate control can be implemented in a television-based entertainment environment when forwarding coded data. Real-time information flows are encoded, transcoded, compressed, etc. into data streams that may be forwarded to other components within an apparatus or to other apparatuses across a network. In a described implementation, a bitcount accumulation of a data stream is monitored in multiple overlapping windows. The data stream is compared to a data limit in each window of the multiple overlapping windows to determine whether an expected bitcount accumulation has been exceeded. The data stream is modified responsive to the comparison(s). For example, if the bitcount accumulations in each window exceed the expected bit accumulations at the corresponding relative positions of each window, then the bit rate of the data stream can be modified by reducing bit rate consumption.
