Abstract
An endpoint system for media communication comprises a resource-limited device and a base station. The resource-limited device at least one of receives and outputs at least one of audio and graphic information. The base station communicates media and control packets with the resource-limited device via a permanent virtual circuit, establishes a switched virtual circuit with an endpoint device via a communications channel, and translates media packets between the permanent virtual circuit and the switched virtual circuit.
Claims36
An endpoint system for media communication, the endpoint system comprising:
- a resource-limited device configured to at least one of receive and output at least one of audio information and graphic information;
- and
- a base station configured to
- negotiate with the resource-limited device to determine a feature subset of the resource-limited device,
- communicate media and control packets with the resource-limited device via a permanent virtual circuit, wherein media packets transmitted from the base station to the resource-limited device are selected based on the feature subset of the resource-limited device,
- establish a switched virtual circuit with an endpoint device via a communications channel, and
- translate media packets between the permanent virtual circuit and the switched virtual circuit,
- wherein the base station is included in one of a cordless telephone base station or a telephone cradle,
- wherein the base station comprises a media converter configured to (i) convert media packets from the communications channel into a first digital audio compression format and (ii) convert media packets from the resource-limited device into a second digital audio compression format,
- wherein the resource-limited device is configured to selectively operate in a standby mode, and in the standby mode, the resource-limited device is configured to power components necessary to monitor for a resume signal from the base station, and
- wherein the permanent virtual circuit includes one of a predetermined user datagram protocol (UDP) port or a negotiated UDP port.
A method for media communication, the method comprising:
- communicating media and control information with a resource-limited device via a permanent virtual circuit, wherein the permanent virtual circuit includes one of a predetermined user datagram protocol (UDP) port or a negotiated UDP port;
- negotiating capabilities with the resource-limited device to determine a feature subset of the resource-limited device;
- transmitting media packets, to the resource-limited device, selected based on the feature subset of the resource-limited device;
- interfacing the resource-limited device with a surrounding environment, where the interfacing includes at least one of capturing and outputting at least one of audio information and graphic information by the resource-limited device;
- establishing a switched virtual circuit with an endpoint device via a communications channel;
- translating media packets between the permanent virtual circuit and the switched virtual circuit;
- converting media packets from the communications channel into a first digital audio compression format and converting media packets from the resource-limited device into a second digital audio compression format;
- and
- operating the resource-limited device in a standby mode, the resource-limited device powering components necessary to monitor for a resume signal.
