Abstract
Abstract According to the present invention, a media manager is provided which incorporates an application program interface (API) for converting high-level generic commands into device-level commands for output to a media device. The inventive media manager includes a high-level command processor which decodes the high-level generic commands and device-specific code mapping modules which convert the high-level generic commands decoded by the high-level command processor into device-level commands. Each of the device-level commands is output from one of the device-specific code-mapping modules to a corresponding one of the media devices. The present invention also encompasses a method of implementing an application program interface (API) for media devices. The method includes receiving high-level generic commands from a computer application, converting the high-level generic commands into device-level commands, and outputting each of the device-level commands to one of the media devices. The present invention also encompasses a computer program product including a computer-readable medium. The computer program product includes means for decoding high-level generic commands, means for converting the high-level generic commands into device-level commands, and means for outputting each of the device-level commands to a corresponding one of the media devices. The present invention further encompasses a common application program interface (API) which converts high-level generic commands received from a computer application into device-level commands which are output to a plurality of media devices including media servers which stores media objects. The common API includes a plurality of individual APIs which each perform a specific function.
