Audio splicing is rendered more effective by the use of one or more truncation unit packets inserted into the audio data stream so as to indicate to an audio decoder, for a predetermined access unit, an end portion of an audio frame with which the predetermined access unit is associated, as to be discarded in playout.

In one embodiment, a method of displaying content portal advertisements and programming advertisements in a video delivery network environment is disclosed. The method includes providing a content portal to a plurality of viewers, the content portal for use by a viewer in navigating video programming. A content portal advertisement queue and a programming advertisement queue are received. Each programming advertisement is linked with one content portal advertisement of the content portal advertisement queue. A programming advertisement is displayed and, when the content portal is invoked immediately subsequent or concurrent to the displaying, the content portal advertisement is displayed. The content portal advertisement queue is reordered by placing the displayed content portal advertisement at the bottom of the content portal advertisement queue.

The 3D models includes parametric data and metadata. A software enables a user to specify search criteria for a selected product among a plurality of products whose 3D models are stored on the data storage device. The search software returns a list of product(s) matching the search criteria. The user selects a product and the 3D model of the selected product is streamed to the user software. The 3D model is then displayed to the user, who now can interact with the 3D model by selecting, hovering over, or decomposing the 3D model to reveal parts or subassemblies of the product in one or more stages of decomposition. Finally, e-commerce software communicates with the user software allowing the user to initiate an ecommerce transaction with respect to the parts or subassemblies depicted in the 3D model of the selected product.

An ad is placed in a movie, by analyzing inherent characteristics of the movie, analyzing viewed characteristics of the movie, analyzing viewer characteristics of a viewer of the movie, obtaining advertiser preferences for placement of the ad in the movie, determining costs of placing the ad in the movie based on the inherent characteristics of the movie, the viewed characteristics of the movie, the viewer characteristics and the advertiser preferences, and placing the ad in the movie in accordance with the inherent characteristics of the movie, the viewed characteristics of the movie, the viewer characteristics, the advertiser preferences and the determined costs.

A system is described for maintaining synchrony of operations among a plurality of devices that have independent clocking arrangements. The system includes a task distribution device that distributes tasks to a synchrony group comprising a plurality of devices that are to perform the tasks distributed by the task distribution device in synchrony. The task distribution device distributes each task to the members of the synchrony group over a network. Each task is associated with a time stamp that indicates a time, relative to a clock maintained by the task distribution device, at which the members of the synchrony group are to execute the task. Each member of the synchrony group periodically obtains from the task distribution device an indication of the current time indicated by its clock, determines a time differential between the task distribution device's clock and its respective clock and determines therefrom a time at which, according to its respective clock, the time stamp indicates that it is to execute the task.

A method and system for planning and running video-on-demand (VOD) advertising includes a planner for planning advertising campaigns and an ad selector for running selected advertisements from selected ones of the campaigns. The campaigns are associated with household demographic classifications, video content category categories, household geographic locations, and/or video viewing times. In response to a viewer requesting a video, the selector selects the campaigns corresponding to the demographic classification associated with the viewer, the content category of the requested video, the geographic location associated with the viewer, and/or the viewing time at which the requested video is viewed. The demographic classification is determined by using an identifier of the viewer's set-top-box. The selector may select the campaigns corresponding to the content categories of the requested video. The content categories are determined by using an identifier associated with the requested video.

A media automation system controls the ability of local stations to automatically replace certain scheduled items. A show is identified as a restricted show, with respect to exclusion of content associated with at least one advertiser. Restriction rules, which are configured to prevent content associated with the at least one advertiser from being scheduled during the restricted show are obtained, and a master broadcast log is generated based on a broadcast schedule and the restriction rules. The local stations are prevented from successfully performing automated replacement of content during the restricted show by inserting a flag into metadata associated with the master broadcast log, the flag specifying a blackout attribute. Buffers can be established around restricted shows, so that spot breaks near restricted shows can also be restricted. A playout system can perform validation checks to ensure that advertisements from advertisers included in the list are not improperly scheduled.
