Abstract
Disclosed are methods, circuits and systems for transmission of a video block. A video stream may be composed of sequential video frames, and each video frame may be composed of one or more video blocks including a set of pixels. Prior to transmission of the data associated with a video block, a signature of the video block may be generated, for example using a spatial to frequency transform such as a two dimensional discrete cosine transform. Signatures of corresponding video blocks across consecutive video frames may be compared in order to determine whether a given video block of a current video frame is static or dynamic relative to prior video corresponding video blocks. Transmission parameters of the given block may depend on whether the block is designated as static or dynamic.
