摘要:
The present invention provides a method involving a media server, a wireless access network, at least one media client, and a proxy server. The method includes accessing, at the proxy server, at least one message including information indicating impending establishment of a media session between the media server and said at least one media client. The method also includes providing, from the proxy server, information indicating the impending establishment of the media session and a request to receive feedback associated with the media session. The method further includes receiving, at the proxy server, feedback associated with the media session in response to providing the request to receive feedback associated with the media session.
摘要:
Methods for proxy-driven content rate selection for streaming media servers are provided. In one method, one or more maximum transmission rate parameters from a network controller are stored at a proxy server in response to a receiver report message from the client. A target rate for the media session is generated based on the stored maximum transmission rate parameters, and the target rate is transmitted to a media server in a proxy-to-server feedback message. The media server selects the content rate from among a plurality of supported content rates in response to the proxy-to-server feedback message from the proxy server, and streams streaming multimedia frames to the client at the selected content rate.
摘要:
In a method for dynamically setting a content rate of a multimedia session for a client in a network, a proxy server receives a channel condition feedback message from a network controller and determines whether a receiver report message has been received from the client since a most recent previous channel condition feedback message. The channel condition feedback message includes current channel condition information for the network. The proxy server sends one of an extended feedback report message and a short feedback report message to a media server based on the determining step. The short feedback report message includes at least a maximum transmission rate parameter for the multimedia session. The extended feedback report message includes at least information contained in the receiver report message. The extended feedback report message may, in addition, include the maximum transmission rate parameter for the multimedia session.

The present invention provides a method involving a media server, a wireless network, and at least one media client associated with at least one air interface with the wireless network. The method includes accessing first information indicative of at least one state of the at least one media client. The first information is provided by the at least one media client. The method also includes accessing second information indicative of resources associated with the at least one air interface. The second information is provided by the wireless network. The method further includes providing at least one feedback parameter to the media server. The at least one feedback parameter is formed based on the first and second information.

摘要:
The present invention provides a method for content rate selection. The method includes selecting a content rate for play out of at least one frame transmitted from a media server to a media client via a wireless access network. Selection of the content rate is performed based on a statistical representation of a bandwidth available for transmission of frames.
