摘要： A computer may be remotely accessed. At a first location, display commands are generated. The display commands are covered into a compressed video data stream. Each display element (50) is checked if it is encoded (52). If object is encoded, it is transcribed into MPEG (54). The image is adjusted for display (56) and compression (58). Additional steps of motion determination (60), change detection (62), compression depth and frame rate determination (66, 68) are executed. Then the data is transmitted to a second location. The display commands are decompressed and displayed as an image at the second location.

摘要： In a method for distributing video information from a central station unit placed on the ground to at least one mobile terminal unit comprising a terminal unit mounted on a mobile object, a request for distribution of the video information is transmitted as request information from the mobile terminal unit to the central station unit by radio communication, and the requested video information is distributed from the central station unit to the mobile terminal unit by digital radio communication. In this method, the video information is hierarchized, and part of the video information in a hierarchical rank according to read right information transmitted together with the request from a mobile terminal is made readable. Further, accounting on the distributed video information in the central station is performed based on accounting information from the mobile terminal. Furthermore, the mobile terminal transmits information indicating the receiving environment of the terminal to the central station together with the request, and the central station changes the method for ensuring transmission quality relating to code errors in the video information distributed to the mobile terminal, in accordance with the receiving environment information.

摘要： Methods, apparatus, systems and articles of manufacture are disclosed for identification of local commercial insertion opportunities. Example apparatus for identification of local commercial insertion opportunities include a media comparator to compare respective instances of media conveyed in respective ones of a plurality of broadcast signals associated with affiliates of a national broadcaster to identify a broadcast interval having different media conveyed among at least some of the broadcast signals. The example apparatus also includes an insertion opportunity identifier to determine whether the broadcast interval is associated with a local advertisement insertion opportunity based on a characteristic of the broadcast interval.

摘要： Systems and methods for identifying, assembling, and transmitting content are described in the illustrative context of electronic program guides and program channels. Data is received over a network from a first user terminal that enables identification of the first user. Program information for a digital program is accessed. A determination is made as to how many interstitials are to be presented during a playback of the digital program. A prediction model is selected and executed to generate predictions of user responses to one or more placements of program interstitials. The user response predictions are used to determine positioning of interstitials with respect to the program. The interstitials are enabled to be displayed on the first user terminal in accordance with the determined positioning.

摘要： Techniques for selecting a picture of a video program for display in accordance with a selected trick play mode of a DVR are described herein. Sometimes, when desired playback speed is faster than normal, a DVR is forced to select some pictures to play and some pictures to skip. Ideally, in order to preserve "smooth" viewing quality, the next picture to be displayed should be temporally close to the currently displayed picture. Since some pictures can take longer to decode than others, accounting for picture decoding costs helps ensure that the best picture can be selected for decoding given playback speed requirements. According to one embodiment of the invention, for each picture of a plurality of pictures in a video data stream, a DVR determines a decoding cost for that picture. Based on the determined costs, the DVR selects a particular picture. The DVR outputs the selected picture for display.

摘要： Methods and systems are described for downloading media assets efficiently and quickly before loss of network connectivity. The method may allow a user to download portions of a media asset in different versions to download a maximum portion of the media asset before loss of network connectivity. Certain versions of media assets may be downloaded more quickly than other versions of media assets. The method may also allow a user to view partially downloaded media assets without network connectivity. The method may also replace portions of media assets downloaded in a first version with portions of the media assets in a second version once network connectivity is restored.
