Claim:
1. A method for reducing blurriness of received video data due to an intra-frame update, the method comprising: receiving video data via a network interface at a decoder; decoding a macroblock derived from the video data, the decoded macroblock corresponding to a macroblock stored in a display buffer; determining, at a filter operatively coupled to the decoder, whether to update a display buffer operatively coupled to the decoder and a display device, based at least in part, on a comparison of a quantization step size of the decoded macroblock with a quantization step size of the corresponding macroblock; and updating, by the filter, the display buffer with the decoded macroblock when the size of the quantization step of the decoded macroblock is smaller than or equal to the size of the quantization step of than the corresponding macroblock stored in the display buffer.
