摘要： Particular embodiments generally relate to video compression. In one embodiment, a store of reference frames is provided in memory. The reference frames may be classified based on a plurality of classifiers. The classifiers may correspond to features that are found in the reference frame. A frame to encode is then received. The frame is analyzed to determine features found in the frame. As macroblocks in the frame are encoded, a macroblock is analyzed to determine which feature may be included in the macroblock. The feature is used to determine a classifier, which is used to determine a subset of the reference frames. The subset is then searched to determine a reference frame for the macroblock.

摘要： A method is provided in one example embodiment and includes receiving a camera dynamic parameter; determining a reference transform parameter based on the camera dynamic parameter; applying the reference transform parameter to generate a video image; and encoding the reference transform parameter in a bitstream for transmission with the video image. In other more specific instances, the method may include decoding a particular video image; decoding a particular reference transform parameter; and applying a particular reference transform parameter to the particular video image. The entropy-decoded data can undergo inverse quantization and transformation such that reference transformed data is combined with the entropy-decoded data. Additionally, the entropy-decoded data can be subjected to filtering before decoded video images are rendered on a display.

摘要： Particular embodiments generally relate to video insertion information insertion in a compressed bitstream. In one embodiment, a compressed bitstream of data is received. Video insertion information to be added to the bitstream is then determined. One or more macroblocks out of a plurality of macroblocks are determined in the compressed bitstream. The macroblocks are determined in the compressed domain and not the spatial domain. Information is selectively inserted for the video insertion information for the determined one or more macroblocks in the compressed bitstream. For example, encoded macroblocks for the video insertion information may replace the determined one or more macroblocks. Also, the one or more macroblocks may be decoded and information for the video insertion information is added to the decoded one or more macroblocks, and then the one or more macroblocks are re-encoded with the information. The re-encoded macroblocks may then replace the determined one or more macroblocks in the compressed bitstream.

摘要： A method of reducing the channel selection transition delay from a first media data channel to a second media data channel includes the operations of accumulating an independent media data frame and any related dependent media data frames based on a first decoder decoding at least a first portion of a second channel to form a second channel current media state, receiving a channel change request from a second decoder to change decoding to the second media channel, identifying an insertion position for a current independent frame relative to a current second channel frame set, and generating the current independent frame based on the second channel current media state corresponding to the insertion position. The dependent media data frames are used to modify the second channel current media state based on the independent media data frame.

摘要： A method and apparatus for mixing first and second video content portions is described. The method may comprise overlapping at least one frame of a first content portion comprising multiple frames with at least one frame of a second content portion comprising multiple frames to produce a composite video content. At least one reference frame comprising a frame of the first or second content portion prior to the overlapping may be designated. The composite video content and the reference frame may then be transmitted, for example, to a client device. The client device may use the reference frame to at least reduce an effect of the overlapping.

摘要： Process for fabricating self-assembled nanoparticles on buffer layers without mask making and allowing for any degree of lattice mismatch; that is, binary, ternary or quaternary nanoparticles comprising Groups III-V, II-VI or IV-VI. The process includes a first step of applying a buffer layer, a second step of turning on the purge gas to modulate the first reactant to the lower first flow rate, then the second reactant is supplied to the buffer layer to form a metal-rich island on the buffer layer, and a third step of turning on purge gas again to modulate the first reactant to the higher second flow rate onto the buffer layer. On the metal-rich island is formed the nanoparticles of the binary, ternary or quaternary III-V, II-VI and IV-IV semiconductor material. This is then recrystallized under the first reactant flow at high temperature forming high quality nanoparticles.
