Abstract: A method and system of transform-based encoding, decoding, and bitstream generation of digital video content. The digital video content comprises a stream of pictures, slices, or macroblocks which can each be intra, predicted or bi-predicted pictures. The pictures, slices, or macroblocks comprise blocks of pixels. The method comprises scanning frequency coefficients from each of the block's two dimensional array of frequency coefficients in a manner that is vertically biased.

Abstract: A method and system of encoding and decoding possible outcomes of events of digital video content. The digital video content comprises a stream of pictures, slices, or macroblocks which can each be intra, predicted or bi-predicted pictures, slices, or macroblocks. The method comprises generating and decoding a stream of bits that represent the outcomes using entries in a lookup table that are periodically rearranged based on historical probabilities of the possible outcomes. The historical probabilities of the possible outcomes are computed by counting occurrences of each of the encoded and decoded outcomes in the stream of pictures, slices, or macroblocks. The periodic rearrangement of the entries in the lookup tables used by the encoder and the decoder is synchronized so that the stream of bits representing the encoded outcomes can be correctly decoded.

Abstract: Apparatus and methods are provided for improving the quality of streaming video delivered to a display device. A current video signal segment is encoded for subsequent decoding at the display device. As part of the encoding step, an estimate is made of the time required for decoding the video signal segment at the display device. If the estimated time exceeds a predetermined decoder time period, either (i) the current video signal segment is re-encoded such that it can be decoded within the decoder time period, or (ii) a subsequent video signal segment is encoded to enable decoding thereof without reference to the current segment.

Abstract: A method and system of encoding and decoding digital video content. The digital video content comprises a stream of pictures which can each be intra, predicted, or bi-predicted pictures. Each of the pictures comprises macroblocks that can be further divided into smaller blocks. The method entails encoding and decoding each picture in said stream of pictures in either frame mode or in field mode.
