Abstract

A server may provide transcoding services (e.g. to transcode Web content for mobile devices) using a plurality of transcoders. To facilitate transcoder selection, server operations may be configured using a configuration framework in which the transcoders and respective mapping priorities are specified. The framework also supports the specification of, for any of the transcoders: a) respective device profile matching data for selecting a particular transcoder in response to a requesting device's profile; and b) a respective next transcoder to invoke thereby to chain transcoder invocations. The framework may be prepared in accordance with an XML schema. The server may be a wireless gateway or proxy server for mobile devices accessing Web-based content.

Claims (18)

1. A method of configuring a server to provide transcoding services, said method comprising:

providing a configuration framework for specifying to the server a plurality of transcoders for transcoding content types to facilitate selection of a one of the transcoders to perform the transcoding, said framework defined for specifying for any of the transcoders a respective mapping priority for an input content type supported by the respective transcoder, such that selection among transcoders capable of transcoding the input content type is responsive to the respective mapping priority.
2. The method of claim 1 wherein the framework is further defined for specifying for any of the transcoders respective device profile matching data for comparison with a device profile of a device requesting the transcoding services, such that selection of a one of the transcoders is responsive to the device profile.
3. The method of claim 1 wherein the framework is further defined for specifying for any of the transcoders a respective next transcoder, such that selection of a one of the transcoders also selects the respective next transcoder for invocation next.
4. The method of claim 1 wherein the framework is further defined for specifying for any of the transcoders a respective initialization parameter for configuring the initialization of the transcoder.
5. The method of claim 1 wherein the framework comprises an XML schema.
6. A computer program product having computer readable code embodied therein, for execution by a processor for configuring a server to provide transcoding services, said computer program product comprising:

a configuration framework for specifying to the server a plurality of transcoders for transcoding content types to facilitate selection of a one of the transcoders to perform the transcoding, said framework defined for specifying for any of the transcoders a respective mapping priority for an input content type supported by the respective transcoder, such that selection among transcoders capable of transcoding the input content type is responsive to the respective mapping priority.
7. The computer program product of claim 6 wherein the framework is further for specifying any one or more of the following for any of the transcoders:

(a) ~respective device profile matching data for comparison with a device profile of a device requesting the transcoding services, such that selection of a one of the transcoders is responsive to the device profile;

(b) ~a respective next transcoder, such that selection of a one of the transcoders also selects the next transcoder for invocation next;
and (c) ~a respective initialization parameter for configuring the initialization of the transcoder.
8. The computer program product of claim 6 wherein the framework comprises an XML schema.
9. A method of providing transcoding services comprising:

selecting a one transcoder from among a plurality of transcoders to transcode content having an input content type, said selecting responsive to a transcoder selection configuration specifying the plurality of transcoders and for any of the transcoders a respective mapping priority for the input content type supported by the respective transcoder such that selection among transcoders capable of transcoding the input content type is responsive to the respective mapping priority.
10. The method of claim 9 wherein the transcoder selection configuration is further for specifying any one or more of the following for any of the transcoders:

(a) ~respective device profile matching data for comparison with a device profile of a device requesting the transcoding services, such that said step of selecting is responsive to the device profile; and (b) ~a respective next transcoder, such that said step of selecting also selects the next transcoder for invocation next.
11. The method of claim 9 wherein the transcoder selection configuration is further for specifying for any of the transcoders a respective initialization parameter for configuring the initialization of the transcoder and wherein the method comprises the step of initializing the transcoders in accordance with any respective initialization parameter.
12. A computer program product having computer readable code embodied therein, for execution by a processor of a server to provide transcoding services in accordance with the method of claim 9.
13. A computer program product having computer readable code embodied therein, for execution by a processor of a server to provide transcoding services in accordance with the method of claim 10.
14. A computer program product having computer readable code embodied therein, for execution by a processor of a server to provide transcoding services in accordance with the method of claim 11.
15. A server for providing transcoding services using a plurality of transcoders, said server comprising:
16 (a) a processor coupled to a memory storing software for execution by the processor, said software defining:

(i) a transcoder selection configuration specifying the plurality of transcoders and, for any of the transcoders, a respective mapping priority for an input content type supported by the respective transcoder; and (ii) transcoder selection operations responsive to said transcoder selection configuration to select a one transcoder from among the plurality of transcoders such that selection among transcoders capable of transcoding the input content type is responsive to the respective mapping priority.

16. The server of claim 15 wherein the transcoder selection configuration further specifies any one or more of the following for any of the transcoders:

(a) respective device profile matching data for comparison with a device profile of a device requesting the transcoding services, such that selection operations are responsive to the device profile; and (b) a respective next transcoder, such that said selection operations also select the next transcoder for invocation next.
17. The server of claim 15 wherein the transcoder selection configuration further specifies for any of the transcoders a respective initialization parameter for configuring the initialization of the transcoder and wherein the server initializes the transcoders in accordance with any respective initialization parameter.
18. The server of claim 15 comprising a proxy server providing proxy services to devices on a network coupled to the server and wherein the transcoding services are providing in association with the proxy services.
