  • Publication number: 20140119457
    Abstract: Disclosed are various embodiments directed to transcoding a media file in parallel. A media file may be accessed, the media file comprising a bit stream expressing a series of pictures. A first random access point in the bit stream and a second random access point in the bit stream are identified. An input segment of the bit stream is generated, the input segment comprising a starting point, the starting point being the first random access point. One of a plurality of transcoders is selected to transcode the input segment for generating a corresponding output segment, each transcoder being configured to operate concurrently in parallel. The output segment is stored in a memory.

  • Patent number: 8106917
    Abstract: Methods and systems for mosaic mode display of video are disclosed. Aspects of one method may include generating video data for a plurality of video windows using a single video feeder module comprising a single video scaler and a single video capture module. The video data for the video windows may be generated in a single frame time. Register DMA may be used to transfer register update data (RUD) to a plurality of registers to configure video processing for generating video data for a video window. The plurality of RUDs may be generated in response to a single interrupt to a processor, and may be configured as a linked list or stored sequentially in memory. The configuring may occur prior to generating video data for the corresponding video window. Video processing for a subsequent video window may be configured automatically after generating video data for the present video window.
