    摘要: At a receiving device after a power-on or physical channel change, the physical channel is monitored for activity relating to services for which electronic service guide (ESG) data had been previously cached. The ESG data for a service will include some service identification information, such as an interne protocol (IP) address associated with the service. The monitoring of the physical channel for activity related to a service can be done by listening for the IP address associated with the service. If activity is detected, the service is determined to be active and its cached ESG data valid. Service acquisition data included in the cached ESG data is used to present the service to the user. The invention thus allows the presentation of services to the user using cached ESG data as soon as the services are detected to be active, without the need to wait for the reception of fresh ESG data. The cached ESG data of services for which no activity is detected is not used and may be deleted from the cache after a certain period.

    摘要: In the transmission of streams of data, such as coded video, staggercasting, in which a primary and a secondary stream are transmitted at some relative time offset (i.e., “staggered”), allows a receiver to pre-buffer frames of the secondary stream to replace frames of the primary stream that may have been lost in transmission. In an illustrative implementation, staggercasting is performed in which the secondary stream contains a subset of the coded video frames transmitted in the primary stream. The primary stream contains reference frames, which are essential to properly decoding the video data, as well as disposable frames which are not. The secondary stream, however, contains copies of the reference frames and may contain copies of some of the disposable frames or no disposable frames at all. When frames of an interleaved stream of the primary and secondary streams are lost, such an arrangement will allow reconstruction at the receiver of an uninterrupted video stream at a temporarily reduced frame rate.

    摘要: A current programming channel, and the content thereon, being displayed on a primary display device are tracked. Web content related to the content being displayed on the primary display device is searched and the resulting data is made available to a user on at least one secondary display device via a user interface. The results of the search are made available to a user such that when data resulting from the search is selected for display on the at least one secondary display device, the data is displayed on the at least one secondary display device without interfering with a display of content on the primary display device. In the event of a change of the programming channel or the content thereon, a new search is initiated for data related to content being currently viewed.
