A video transmission system includes an encoder and a decoder. As video data is encoded, the system uses temporal or spatial prediction to reduce the number of bits needed to encode frames. An increase in the complexity of the data results when a scene change occurs. The scene change is detected for intra-frame and inter-frame frames by monitoring statistics for the macroblocks within the current frame. Once the scene change is detected, the encoder or the system takes actions to prevent latency, bit rate fluctuation or quality degradation for the video transmission.
