摘要： A system for producing fragmented video content is provided. The system includes a processing device, a non-transitory data store, and a memory storage device having at least a Manifest Processing Service (MPS) unit stored therein. The MPS unit is configured to generate at least one master manifest and store the master manifest in the non-transitory data store, the master manifest comprising a timing reference for a video fragment of the fragmented video content, wherein the timing reference indicates a temporal boundary of processing for the video fragment.

摘要： A video stream is transcoded to provide a plurality of primary profiles. Individual frames of the video stream have a Presentation Time Stamp (PTS). A PTS is used as a token to identify particular frames to be encoded as Instantaneous Decoder Refresh (IDR) frames in each profile. An IDR frame period is determined, indicative of a desired number of video frames between two IDR frames. An IDR frame is inserted into each profile every IDR frame period. The IDR frames of each profile are aligned with the same IDR frames of the other profiles. The PTS of each IDR frame in each profile is monitored. Upon determining that a PTS is out of alignment, the next PTS of the affected profile is aligned with the corresponding PTS of remaining profiles. Backup transcoders produce backup profiles that are maintained in alignment with each other and with the primary profiles.

摘要： A technique wherein the number and position of a quantization parameter node is determined in response to the quantization parameters and a preselected error. The size of scene graph and the corresponding amount of memory required to store the scene graph can be reduced by selective placement of quantization parameter nodes in a scene graph. The scene graph is traversed depth first to establish an order and then traversed in reverse. At each node, a calculation relating to (1) the relative cost of inserting a quantization parameter node and (2) the relative savings that result from insertion of a quantization node is performed. Quantization parameter nodes are selectively placed in response to a result of these calculations. The maximum degree of acceptable error value is chosen for each quantization type. This error value limits the number of quantization parameter nodes that can be placed in a scene graph.

摘要： A method and an apparatus for driving a passive liquid crystal display to obtain a high contrast ratio for both still image and video modes includes driving some or all of the row lines simultaneously. The row voltage wave forms are defined as a set of orthogonal functions and the column voltage wave forms are defined as a linear combination of the row voltages. The mean square voltage across each pixel and row is specified, and the corresponding column coefficient is calculated from which all coefficients in a column can be determined.

摘要： Methods and apparatus for delivering video programs are provided. A plurality of video programs are provided in a fragmented, adaptive bit rate format. A request for a respective video program from the plurality of video programs is received from each of a plurality of clients. The requested video programs are multiplexed for delivery to the clients in a multiplex over a shared, fixed-bit-rate transmission channel. The requests may be for the same or different video programs. The requests for the video programs may occur at the same or at different times. In the fragmented, adaptive bit rate format, the fragment delivered to the client may not be the same as the requested fragment and is dependent on multiple criteria, including the bitrate and quality of the requested and delivered fragments, the total available delivery bandwidth, and other fragment requests made on the channel. The resulting multiplex may be either a constant bit rate multiplex or a variable bit rate multiplex.

摘要： A transformation of a data object called a personal logo contains personal data for transmitting from a client computer to a server computer. The personal data is embedded into transformation coefficients derived using one of several encoding techniques. The personal data is extracted from the transformation coefficients by the server computer to complete the transaction. The personal logo is created by or selected by a user and is made unique using a randomization algorithm to ensure differentiation from every other personal logo. Personal data is embedded into the unique personal logo in a way that hides it and makes it difficult for an unauthorized party to extract. The personal data includes data use limitations that limit what an authorized receiver may do with the personal data after receipt. Network transactions are automated through the creation of a drag-and-drop interface representing the act of data transmission. The particular personal data to be transmitted is requested by an application server and approved by the user. Keystroke errors are limited due to the automated nature of the transaction.
