Abstract: An intermediate device receives a content data message addressed to a receiving device for a communication session between a source device and the receiving device. The intermediate device substitutes adapted content data for content data of the content data message and then sends the adapted content data to the receiving device such that it appears to the receiving device that the adapted content data originated from the source device.

Abstract: An intermediate device receives a content data message addressed to a receiving device for a communication session between a source device and the receiving device. The intermediate device substitutes adapted content data for content data of the content data message and then sends the adapted content data to the receiving device such that it appears to the receiving device that the adapted content data originated from the source device. The communication from the source device to the receiving device is intercepted by the intermediate device in a manner that is transparent to the source device and receiving device.

Abstract: Data packets to be transferred over a network as part of a temporally ordered content stream are obtained by an adaptive progressive download (APD) server. The APD server divides the data packets of the content stream into epochs of contiguous data, the epochs including a current epoch. The APD server determines a bit rate available on the network for transferring the current epoch and calculates an estimate of a playback time of the content stream buffered at a computer to which the content stream is being transferred and played back. The calculation of the estimate is based at least in part on the bit rate available on the network and an encoding bit rate of the content stream. The APD server controls the transfer of the content stream over the network in accordance with the estimated playback time.

Abstract: Network transmission of live digital content from sources to receiving devices is enabled with real-time encoding, customization, and transmission of the live content according to user preferences, receiving device characteristics, network conditions and the like. Content, such as advertising customized to user profile and user location, may be conveniently inserted into the live content. Source-to-screen delay from sources to receiving devices is reduced and channel switching is supported.

Abstract: A personalized presentation is provided to an intended recipient through a network communication system by selecting personalization content for an associated presentation template in accordance with contemporaneous information relating to an intended recipient and generating an assembled presentation comprising the selected personalization content and the associated presentation template such that the assembled presentation can be sent to the intended recipient.

Abstract: A method and system are provided for wireless multimedia customization for different access networks with variable network conditions and device types. In one aspect, when a multimedia content clip is available, the clip is processed for transport by processing it in accordance with different options for the content clip in an optimized way that helps dynamic customization. For example, instead of preparing a version of the entire content clip, targeted for a particular network condition and target device characteristics, or creating a separate processed clip for each compression parameter available, a set of content ingredients are generated that can address a wide range of network conditions even through dynamic fluctuations in conditions and device characteristics.
