摘要： A method for performing texture decoding in a multi-threaded processor includes substantially simultaneously decoding, in multiple hardware threads, at least two macro-blocks of a VP8 frame. Each hardware thread decodes one macro-block at a time. The method may also include assigning a macro-block from the at least two macro-blocks of the VP8 frame to a hardware thread of the multi-threaded processor.

摘要： Techniques for reducing bus traffic during texture decoding of a video bitstream are provided. In one configuration, a wireless communication device (e.g., cellular phone, etc.) comprises a processor configured to execute instructions operative to decode and separate in a bitstream macroblock (MB) information and residual packet data. The residual packet data is used to generate codec-independent non-zero MB-packets having a universal order that is codec independent. The codec-independent non-zero MB-packets and MB information are then used for reconstructing pixels of a respective frame of the video bitstream.

摘要： A method and system are disclosed for controlling the generation of a systems layer stream, such as a transport stream, that carries a program made up of at least one elementary stream, such as an encoded audio signal or an encoded video signal. The systems layer stream is made up of serial segments, such as packets, which contain information specific to the systems layer, such as headers, and segments of elementary stream data. The bit rate of one or more of the elementary streams is adapted in accordance with a dynamically changing relation that relates the bit rate of such elementary streams to the bit rate of the portion of the systems layer stream that carries them.

摘要： A method of treating a patient is described herein. The method can include the steps of identifying a target that contains biological tissue and directing one or more pulses of electromagnetic radiation at the target. The pulses of electromagnetic radiation can cause a temperature increase per unit of time in the biological tissue. Additionally, the temperature increase per unit of time can cause the change in the cell function in the biological tissue and can be within a range of approximately one degree Celsius per second to approximately one degree Celsius per microsecond.
