Abstract: The present invention is directed to playing an alternative pre-stored content in place of a particular type of content received by the player within a transport stream comprising a plurality of types of content. The invention can be useful in providing targeted advertising, where, when combined with profiling techniques, alternative content of interest to a viewer can be substituted in the transport stream in place of the received content. According to other embodiments of the present invention, computing resources and communication bandwidth use can be saved by playing pre-stored content instead of the received content. Embodiments of the present invention provide for the maintenance of the pre-stored material by storing appropriate content as it is received in the transport stream or by deleting pre-stored content when deemed appropriate to do so. An embodiment of the present invention may be deployed in a personal video player/recorder.

Abstract: This disclosure describes computer architectures, software, and methods by which a custom signaling protocol is implemented for communicating between an app on a mobile device and an app that is either on a local area network or on a mobile device using a special-purpose cloud service. The cloud service translates messages from the mobile app protocol into SIP and also tracks the power state of the mobile app, and translates the SIP protocol back to the mobile app protocol when sending the signaling messages to the mobile app. The decentralized architecture maintains interoperability with SIP networks and presents an interface better suited to the needs of mobile apps. Additional embodiments provide computer architectures, software, and methods for transmitting audio-video data between mobile apps with changing IP addresses without the need to drop the call.
