Abstract: An encoding method includes: encoding transform coefficients of a transform coefficient block according to a predetermined scan order, and encoding a set number of transform coefficients in each group until a last group of the transform coefficient block is encoded; storing an obtained map of non-zero transform coefficients, absolute values of transform coefficients, and positive and negative signs of non-zero transform coefficients; when the last group is being encoded, encoding the stored map of non-zero transform coefficients and the map of non-zero transform coefficients encoded in the last group into a bit stream; and encoding the stored absolute values of transform coefficients and positive and negative signs of non-zero transform coefficients and the absolute values of transform coefficients and positive and negative signs of non-zero transform coefficients encoded in the last group into the bit stream.

Abstract: Disclosure of the present invention provide a method and an apparatus for processing a video stream. The method includes: acquiring a request message from a terminal, where the request message carries address information of multiple sub video screens, according to the address information, acquiring multiple substreams corresponding to the multiple sub video screens in a one-to-one manner, merging the multiple substreams into a single stream, and generating an indication message used to indicate a picture parameter of the single stream, and sending the single stream and the indication message to the terminal, so that the terminal decodes the single stream and displays decoded multiple sub video screens according to the indication message.
