A method of assigning network resources between network endpoints includes providing a session initiation request to an application manager. The application manager is logically and physically decoupled from an application server associated with the network endpoints. This request initiates communication between the network endpoints through the set of network resources. The communication employs an application residing on an application server. The method also includes providing a PCMM message from the application manager to a policy server as a result of the session initiation request. The PCMM message includes at least some information, for example QoS information, embedded in the session initiation request. The method further includes selecting, via the policy server, a set of network resources for creating a path connecting the network endpoints. The policy server selects the set of network assets based on the PCMM message, for example to set QoS for the communication between the two endpoints.

The invention relates to the reproduction of a television signal on a distant reproduction device. The received television signal is encoded and transmitted in a digital data format over a communication link to the reproduction device. The reproduction device decodes the received video information for display on a display screen. The invention is particularly intended for use in mobile vehicles, coaches and trains, where the signal strength of a received television signal during travel is continuously varying and signal distortions occur frequently. In order to reduce the effect of signal distortions on the perceived image and audio quality, the invention inserts a compressed pre-stored video or audio data into the data stream transmitted from the television receiver to the reproduction device upon detection of a television signal distortion. Thus, the decoding procedure at the display device can be maintained in spite of a received television signal of insufficient signal strength.
