The present invention is directed to an application programming interface. More specifically, the present invention relates to an application programming interface designed for handling interaction between an audio/video controller and an audio/video file system. In one exemplary embodiment, the application programming interface includes a number of function calls which direct the audio/video file system to perform a variety of functions. In addition, the application programming interface permits devices capable of handling different types of data, such as isochronous and asynchronous data, to communicate with the audio/video file system.

Application programming interface for communication between audio/video file system and audio video controller

A method of reading multimedia information which is capable of realizing optimal data access in consideration of the type and content of data to be accessed and the relationship to other data during access. The method involves reading first and second information from a storage medium, multiplexed with each other, where response time guarantee is of relatively higher importance for the first information and reliability is of relatively higher importance for the second information. Management of the read time is performed on both the first and second information. A plurality of processing methods are pre-defined as error countermeasure methods for the case where an error occurs in information read out when reading the first or second information in units of predetermined amounts. When reading information, one of the plurality of error countermeasure processing methods is selected and set for use.
