    摘要： A method and mechanism for repositioning video images in a compressed data stream without requiring bit shifting. A P frame image is to be repositioned from an original position to an alternate position. The P frame image data is analyzed to determine whether the repositioning will result in the image data bit positions being changed with respect to the original image. In response to determining the bit positions will be changed, the original image data is modified by adding stuffing bits in the form of a stuffing macroblock to restore the image data to its original bit positions. The P frame is intra-coded and the stuffing macroblock is non-intra coded. A non-intra quantization matrix is selected such that upon decode the stuffing macroblock data does not adversely affect the final picture. Maintaining the original bits positions of the image data facilitates a straightforward copy of unmodified data from the original P frame to the new P frame.

    摘要： A method and apparatus for aggregating the data for a plurality of individualized programs into a single channel, and allocating the channel bandwidth as-needed for provision of short video programs on an nullon demandnull basis, so that the total bandwidth required to provide the individualized channels and associated video clips is substantially reduced. Also provided is a real-time, single-user-targeted individualized advertising associated with the viewer selection that personalizes the user's iTV experience. The advertisements are targeted in real-time based on an immediate interest revealed by the user in a search request for content. Short duration videos are provided so as not to over-tax the individualized nullon demandnull channel's limited bandwidth.

    摘要： A smart playlist system is described. In one example embodiment, a collector module obtains content utilization data from a plurality of client devices associated with respective plurality of viewers. A hot list generator module generates a list of popular content items based on the obtained content utilization data. A customization module generates a customized playlist for a target viewer from the plurality of viewers, based on the list of popular content items and a profile of the target viewer. The communications module communicates the customized playlist to a client device of the target viewer.

    摘要： Methods and systems for transmitting and receiving data, such as, for example, entertainment data, are presented. In one example, a data file is segmented into a plurality of data modules. A header is generated for each of the data modules, with the header including a module identifier for the data module associated with the header. An indication of a number of the plurality of data modules associated with the data file, and at least one multicast address from which the plurality of modules may be received via a multicast transmission, are generated and transmitted. The data modules with their associated headers are transmitted over a communication network in the multicast transmission.
