    摘要: A video compression scheme enables the user to select one of many video compression formats, including the widely-used standard video formats such as MPEG-1, MPEG-2, MPEG-4 and H.263. In one embodiment, the scheme is implemented as a hardware-software combination, with the hardware portion, preferably implemented as an ASIC chip, performing the core compression and the software portion dealing with the detailed formatting. In another embodiment, a 32-bit aligned transitional data format is used.

    摘要: According to one embodiment, the present invention generates a test vector for verification of a video encoder or decoder by encoding video data using a permissible combination of parameters. One embodiment of the present invention provides for verification of a video decoder by performing at least one video decoding operation and comparing a resulting partially or fully decoded test vector to an expected value. Another embodiment of the present invention provides for verification of a video encoder by performing at least one video encoding operation using a selected combination of parameters, and comparing a resulting partially or fully encoded test vector to an expected value.

    摘要: A design technique is disclosed that allows video processing hardware designers to effectively employ the requirements of a video processing standard (e.g., H.264 specification or other such standard) during the hardware architecture design phase of the design process. The technique eliminates or otherwise reduces costly multiple passes through the resource intensive implementation and verification portions of the design process, and allows designers to make changes to the hardware architecture design, thereby ensuring verification at the implementation phase.

    摘要: A noise filter for a video processing system includes a block selector, a cost calculator, a cost table, a cost comparator, and a coefficient filter. The block selector is coupled to receive data from the quantization unit and selects blocks for additional filtering. The selected blocks are provided to the cost calculator determines a cost for each of the coefficients in the block using the cost table and the costs are summed. The cost comparator compares the total to a threshold, and filters the coefficients using the coefficient filter if the total is greater a preset threshold. The noise filter to the VLC unit then outputs the filter data.
