Abstract: In one embodiment, a tiled video display is shown on a screen of a display device. The tiled video display includes a plurality of video tiles that each show video content of a different video stream. The video tiles are arranged on the screen according to a tiling layout. A user interface (UI) is shown on a touch sensitive screen of a wireless mobile device separate from the display device. The UI includes a plurality of UI tiles that each correspond to a respective video tile of the tiled video display. The UI tiles are arranged on the virtual display screen according to the tiling layout of the video tiles. In response to a gesture over at least a portion of a particular one of the UI tiles on the touch sensitive screen, a modification is made to both the particular UI tile and a correspond video tile.

Abstract: A subscriber of a communications network is enabled to top-up an account for a multimedia service provided on the communications network while the service is being provided. Real-time prepaid charging may be applied to a multimedia service being provided to a subscriber of a communications network. Both a count and a time period may be determined from an account balance, and the number of information units exchanged during the service and the duration of the service may be compared against the count and time period, respectively. Further processing may be defined to be performed if either and/or both thresholds are reached. A subscriber of a communications network may be notified of a threshold amount of service being reached while the service is being provided using the same session as is being used to provide the service (in-band) or using a different session (out-of-band).
