Abstract
Disclosed herein are methods and systems for selecting a coding scheme for application-session content in an application session between a server and a client device. In an exemplary embodiment, the client device receives application-session content from the server via a communication path that comprises a wireless link. An exemplary method may involve (a) at the client device, determining current values of one or more quality-of-service indicators, wherein the quality-of-service indicators are indicative of quality of service over the wireless link; and (b) using the current values of the quality-of-service indicators as a basis for selecting a coding scheme that should be used to encode forthcoming applicant-session content. Further, if the selected coding scheme differs from the coding scheme being used by the server, the client device may request that the application server use the selected coding scheme.
