摘要： Accelerated channel change (ACC) strategies are described for supplying a client module with media information by transitioning between a first delivery of media information provided by first delivery functionality and a second delivery of media information provided by second delivery functionality without exceeding prescribed data rate limitations. The first delivery functionality can represent server-based functionality for delivering a unicast stream of media information at a data rate (or maximum data rate) of some excess amount over the nominal rate of delivery, starting at a selected location within the media information. The second delivery functionality can represent any functionality for delivering the media information at the data rate (or maximum data rate) of the nominal rate of delivery. A join interval separates the first delivery at the excess rate and the second delivery at the nominal rate. In that period, the first delivery functionality can provide media information at a join interval data rate. The join interval data rate, if it is below the nominal data rate, will cause the client module to miss packets of media information. The client module can receive these missing packets by issuing retry requests to the first delivery functionality or to some other entity. The client module can determine the excess amount available by investigating the amount of missing information that occurs at different data rates; or the excess amount can be defined in advance.

摘要： Systems and methods are described for broadcasting interactive content without using triggers embedded in the broadcast content. When a viewer sees an item of interest while viewing a program, the viewer can initiate a request for information (RFI) about that item with a single button actuation. When the RFI is entered, a client device, such as a set-top box, detects the RFI and transmits RFI data to a server, including the channel viewed, a time stamp and - in at least one implementation - a system-defined amount of closed captioning data. The RFI data is cross-referenced with program time code information, prog-ramming guide information, program information and/or advertiser information to determine the context of the RFI, i.e. what the user saw that made the user enter the RFI. Information about the item is then sent to the viewer as a system message, an e-mail message, a post, or by way of any other delivery mode.

摘要： In an implementation of virtual channel preview guide, a different virtual channel is associated with each of one or more recorded programs. A virtual channel preview guide is generated to display the different virtual channels and the associated recorded programs. In an event that a virtual channel is selected, a preview of a recorded program associated with the virtual channel is initiated.

摘要： An electronic program guide (EPG) is enhanced to have entries that enable access to one or more images. When an image-related entry is selected by a user, a television-based device presents the one or more images that are associated with the selected entry. In a described search-related implementation, portions of the EPG, such as actors and actresses names, are presented as links. Selection of a link effectuates a search of a group of files and is followed by the visual presentation of a slide show of images resulting from the search. In a described email-related implementation, a third party can email images to an email address that is associated with the television-based device. In response to the emailed images, an image entry is added to the channel lineup of the EPG. Selection of the image entry causes the device to visually present the emailed images in a slide show.

摘要： Fast channel changing in digital-television-based entertainment networks can be implemented, for example, by electing to tune to channels at opportune tuning times. In an exemplary implementation, a method includes: receiving a channel change request that indicates a requested new channel from a client device; preparing a broadcast video data stream of the requested new channel that is offset in time behind a current broadcast time for broadcast video data of the requested new channel; and streaming the broadcast video data stream responsive to the channel change request. In another exemplary implementation, a system includes: a storage device (408A) that retains broadcast video data (410) for multiple channels; a video data extractor (416) that accesses the retained broadcast video data and retrieves an intra frame of broadcast video data that is in the past for a requested channel; and a video data distributor (418) that transmits the retrieved intra frame of broadcast video data.

摘要： A program guide data text search system generates a directed acyclic word graph that includes words from program guide data. When receiving a request to search for and display programming information, the directed acyclic word graph is searched to determine whether the requested information is included in the program guide data. An indication is provided to notify a viewer whether or not the requested information is available in the program guide data.

摘要： Program data for use in electronic program guides is selected for storage at a low resource client according to a preference for current program data over program data for a future time. In the described implementation, a memory representative of the client memory is disproportionately allocated for different time units (e.g., 24-hour days) to be represented in an electronic program guide. Analysis is conducted as to whether program data for the different time units can fit in the portions of memory and adjustments to the amount of program data for respective time units are made. Different-size sets of program data are eventually selected such that more program data will be stored in the portion of memory corresponding to the current time unit and progressively less program data will be stored in other portions of memory corresponding to future time units.
