A client-to-service compatibility framework is described that allows online entities to provide a single set of service offerings for client devices of multiple different brands and/or models, such as televisions, set-top-boxes, game consoles, and portable media players, for example. Generally, the client-to-service compatibility framework comprises a plurality of plug-ins or adapters that translate communications from client devices to a form compatible with the online entity's service offerings and vice versa. In this manner, online entities are able to insulate their service offerings from the changing communication needs of client devices.
