摘要： Disclosed herein are representative embodiments for performing entropy coding or decoding using a counter-based scheme. In one exemplary embodiment disclosed herein, a first codeword is received from compressed digital media data. The first codeword is decoded into a first digital media data value by referencing a codeword table that associates the first codeword with the first digital media data value and a second codeword with a second digital media data value. A counter for counting occurrences of the first digital media data value is incremented. The value of the first counter is compared with the value of a second counter that counts occurrences of a second digital media data value. If the value of the first counter and the value of the second counter are equal (or greater than or equal), the codeword table is updated to swap codewords between the first and second digital media values.

摘要： A device for encoding digital signals corresponding to images which are subdivided into blocks has a first encoding channel including a discrete cosine transform circuit. In addition to this first encoding channel the device has a second encoding channel which encodes the differences between the original coefficients present at the output of the discrete cosine transform circuit and the same coefficients after quantization and inverse quantization. This second channel encodes the differences after they are quantized with a finer quantization step than in the first encoding channel. The device further includes a prediction channel including a motion compensation stage, that uses both the inverse quantized coefficients coded in the first encoding channel and the inverse quantized coefficients coded in the second encoding channel to produce a predicted digital signal. This predicted digital signal is subtracted from the digital signal to be encoded by the device.

摘要： Context adaptive video coding is described in which encoding and decoding relies on deriving context adaptive coding tools, which can be applied within a coder (encoder and/or decoder) to one or more coding processes. A discontinuity of the block is identified, and a context feature extracted having directionality and location of discontinuity. Coding then uses the context adaptive tools to enhance coding efficiency, without the need of additional side information. Context adaptation according to invention can be applied such as to inter prediction, intra prediction, transform, interpolation filtering, and/or scanning.

摘要： Active control of the output bit-rate of a system of constant bit-rate encoders is provided to match their aggregate bit-rate to the available network bit-rate of a communication channel over which a packetized data stream is to be transmitted. Cross-layer optimization is achieved between network layer performance metrics, such as queue size, round-trip-time delay, and available bit-rate, and application layer requirements of the data encoders, such as output bit-rate, input frame-rate, and packet loss, through a tight coupling of these parameters. Complex run-time calculations or heavy network probing are avoided while achieving the beneficial results, which is advantageous in systems that deal with real-time applications, such as live video streaming for video surveillance and security.

摘要： A video stream is transcoded to provide a plurality of primary profiles. Individual frames of the video stream have a Presentation Time Stamp (PTS). A PTS is used as a token to identify particular frames to be encoded as Instantaneous Decoder Refresh (IDR) frames in each profile. An IDR frame period is determined, indicative of a desired number of video frames between two IDR frames. An IDR frame is inserted into each profile every IDR frame period. The IDR frames of each profile are aligned with the same IDR frames of the other profiles. The PTS of each IDR frame in each profile is monitored. Upon determining that a PTS is out of alignment, the next PTS of the affected profile is aligned with the corresponding PTS of remaining profiles. Backup transcoders produce backup profiles that are maintained in alignment with each other and with the primary profiles.
