    摘要： A video encoding system uses both a central processing unit (CPU) and a graphics processing unit (GPU) to perform video encoding. The system implements a technique that enables the GPU to perform motion estimation for video encoding. The technique allows the GPU to perform a motion estimation process in parallel with the video encoding process performed by the CPU. The performance of video encoding using such a system is greatly accelerated as compared to encoding using just the CPU. Also, data related to motion estimation is arranged and provided to the GPU in a way that utilizes the capabilities of the GPU. Data about video frames may be collocated to enable multiple channels of the GPU to process tasks in parallel. The depth buffer of the GPU may be used to consolidate repeated calculations and searching tasks during the motion estimation process.

    摘要： The techniques and mechanisms described herein are directed at transmitting elementary streams in a broadcast environment. The mechanisms provide a buffer controller and packet scheduler that allow a media format to be transmitted through the broadcasting environment in a manner resulting in a low channel switch delay. A buffer-fullness indicator allows the operation with various types of decoders. A lower bound and an upper bound are calculated for each frame within the elementary stream. The lower bound corresponds to an earliest time for sending the frame without causing an overflow condition within a decoder buffer. The upper bound corresponds to a latest time for sending the frame without causing an underflow condition within the decoder buffer. A send time is then scheduled based on the lower bound and the upper bound that determines when a packet associated with the frame is transmitted over a channel in a broadcast environment.
