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.

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： A dual mode facsimile data compression technique which possesses the advantage of symbol recognition and extended run-length coding methods. In operation, a symbol blocking operator isolates digital raster data representing valid alphanumeric characters and document symbols. The first symbol encoungered is placed in a memory or library and as each new symbol is detected, it is compared with each entry of the library. If the comparison is within a predetermined tolerance, a library identification code representing the symbol is generated and transmitted along with the symbol location coordinates. Otherwise, the new symbol is placed in the library and its digital pattern and location is transmitted. A scoring system determines which elements of the library are to be replaced by new prototypes once the library is filled. Non-isolated symbols are coded by a two-dimensional run-length coding method for transmission.

摘要： A digital video compression and expansion system and its methods for compressing and expanding digitalized video signals in real time at rates up to NTSC color broadcast rates are disclosed. The system compressor receives digitalized video frames divided into subframes, performs in a single pass a spatial domain to transform domain transformation in two dimensions of the picture elements of each subframe, normalizes the resultant coefficients by a normalization factor having a predetermined compression ratio component and an adaptive rate buffer capacity control feedback component, to provide compression, encodes the coefficients with a minimum redundancy coding scheme and stores them in a first rate buffer memory asynchronously at a high data transfer rate from which they are put out at a slower, synchronous rate. The compressor adaptively determines the rate buffer capacity control feedback component in relation to instantaneous data content of the rate buffer memory in relation to its capacity, and it controls the absolute quantity of data resulting from the normalization step so that the buffer memory is never completely emptied and never completely filled. In expansion, the system essentially mirrors in reverse the steps performed during compression. An efficient, high speed decoder forms an important aspect of the present invention. The compression system forms an important element of a disclosed color broadcast compression system.

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.
