Abstract: A method and system for efficiently organizing data in memory is provided. Exemplary aspects of the invention may include storing linear data and block data in more than one DRAM device and accessing the data with one read/write access cycle. Common control signals may be used to control the DRAM devices and the address lines used to address each DRAM device may be independent from one another. The data read from the DRAM devices may be reordered to make the data more suitable for processing by applications.

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.

Abstract: Aspects of an edge smoothing block filter and combinations of the filter with a motion compensated temporal filter are described. In one embodiment, edge smoothing block filtering includes selecting a current pixel to be filtered and selecting a candidate pixel within a search area about the current pixel. The edge smoothing block filtering generally seeks to identify candidate pixels having surrounding pixels similar to pixels surrounding the current pixel. The edge smoothing block filtering further computes a cost difference between pixels within a candidate pixel neighborhood and pixels within a current pixel neighborhood, and filters the current pixel based on the cost difference. Aspects of the filters and filter element combinations may preserve edges and textures adaptively based on image content. For example, diagonal or curved image edges may be filtered along edges while texture is preserved along the edges.

Abstract: A system includes a first processing component, a second processing component, and an adapted bus linking the first and second processing components. The adapted bus may account for a circuit characteristic or on-chip variation in the system. For example, the bus may be adapted to include a wider data width because of an effect of the on-chip variation that limits performance of the bus at a lower data width. The bus may include a widened data width for a portion of the bus. In that regard, the bus may include a bus expander and a bus narrower for adjusting the data width of the bus.

Abstract: Embodiments for video content source resolution detection are provided. Embodiments enable systems and methods that measure video content source resolution and that provide image-by-image source scale factor measurements to picture quality (PQ) processing modules. With the source scale factor information, PQ processing modules can be adapted dynamically (on a picture-by-picture basis) according to the source scale factor information for better picture quality enhancement. In addition, embodiments provide source resolution detection that is minimally affected by video coding artifacts and superimposed content (e.g., graphics).
