A client device receives a broadcast content signal containing an interactive identifier over a managed network at a client device. The interactive identifier may be a trigger that is included in a header or embedded within the digital video data. The trigger may have a temporal component, wherein the trigger can expire after a certain period of time. In response to identification of the trigger, the client device sends a user request for interactive content over an unmanaged network. For example, the managed network may be a one-way satellite television network, IP-television network or cable television network and the unmanaged network may be the Internet. The client device switches between receiving data from the managed network to receiving data from the unmanaged network.

This invention describes a new methodology for a cell reselection by a mobile station (MS) for improving network interconnection and interoperability in a limited mobile access environment. The invention is applicable to any kind of networks and their interconnections. The invention describes how the MS can better recover from failed intersystem cell reselection attempts so that there are fewer subsequent failed attempts using two major improvements. First, the MS takes into consideration during cell reselection evaluation and candidate-cell selection, whether the MS had previously been unsuccessful in reselecting the considered cell. This means treating neighbor cells to which the MS had failed reselection before with a lower priority in subsequent cell reselection evaluations. Second, the MS is allowed to stop monitoring and thus, to stop evaluating cells if it was earlier found that the access to those cells is forbidden.

A coordinated adaptive streaming system provides a level of intelligence between adaptive streaming heuristics applied to multiple multi-bitrate streams playing on a client computer at the same time. The system receives a media event that includes multiple multi-bitrate streams and plays two or more of the streams. Each stream registers with the coordinated adaptive streaming system so that the system is aware of each of the streams. The system receives a priority indication from each stream that indicates the priority of the stream relative to other streams associated with the media event. The system uses the received priority indications to make adaptive streaming decisions. Thus, the coordinated adaptive streaming system provides playback that more closely aligns with a user's priorities and provides a higher quality experience to a user viewing multiple concurrent media streams.

Disclosed is an engine control method for a vehicle having an electronically controlled drive line such as an electronic multi-speed transmission with an automatic gear box. The method of operation comprises the steps of turning on the engine and then keeping the engine revs high whilst an engine is idling and not connected to a transmission system, for instance whilst the neutral position is selected. The high idle speed is maintained on sensing that the gear select is moved from neutral to drive and the controller delays dropping the engine idle speed and engaging the drive line until the wheel brake is removed. Sensors may be provided to detect release of the wheel brakes and gear position. The method is used to provide a high engine operating speed on engine start up and/or warm up to ensure that the engine heats up rapidly so that the hot exhaust fumes can be used to heat a catalytic convertor to bring it to its active operating temperature.
