Abstract: The method, system, and apparatus of linear temporal reference scheme having non-reference predictive frames is disclosed. In one embodiment, a method of a temporal reference scheme includes creating a non-reference predictive frame and a reference predictive frame from a reference frame, increasing a quantization factor of the non- and reference predictive frame by a threshold value, and decreasing the quantization factor of the reference predictive frame by the threshold value. The method may include toggling between the temporal reference scheme and another temporal reference scheme in which there may be no non-reference predictive frames and only reference predictive frames based on a scenario. The method may also include calculating a target bit rate across a communication channel through a bit rate calculation algorithm that considers a bandwidth capacity across the communication channel.

Abstract: This invention is a method of video encoding. The number N macroblocks stored in a temporary buffer depends upon an estimated number of motion vectors. N macroblocks of current and prior frame data is transferred to the temporary buffer. The invention determines for each macroblock whether to be inter frame predicted or intra frame predicted. The inter and intra macroblocks are separately encoded based upon this determination and stored in an output buffer. Output macroblocks are output from the output buffer in raster scan order. This technique permits the process to loop over differing number of macroblocks in differing parts of the encoding process. Entropy encoding complexity from separating inter and intra macroblock encoding is avoided by separating a symbol generation phase from an encoding phase.

Abstract: Several methods and systems for facilitating multimedia data encoding are disclosed. In an embodiment, a plurality of picture buffers associated with multimedia data are received in an order of capture associated with the plurality of picture buffers. Buffer information is configured for each picture buffer from among the plurality of picture buffers comprising at least one of a metadata associated with the corresponding picture buffer and one or more encoding parameters for the corresponding picture buffer. A provision of picture buffers in an order of encoding is facilitated based on the configured buffer information.

Abstract: A method for making a slice cap decision during encoding of a video sequence in a video encoding pipe is provided that includes determining a prediction mode for a macroblock, computing an estimated encoded size of the macroblock based on an adaptive macroblock size estimation model, and making a slice cap decision for a current slice based on the estimated encoded macroblock size, wherein the slice cap decision is made prior to entropy coding the macroblock.
