Patent ID: 8873937

Claim:
An audiovisual data transmission system comprising: a filesystem module configured to create a file that contains at least one of video data and audio data stored in a storage unit; a conversion processing unit configured to manage a file created by the filesystem module; a filesystem-in-userspace module configured to provide an interface between the conversion processing unit and the filesystem module; an update detecting unit configured to detect an update of at least one of video data and audio data contained in a file; and a server configured to, in response to an instruction to acquire a file managed by the conversion processing unit received in a state where an update of the file is detected by the update detecting unit, (a) make an inquiry to the conversion processing unit via the filesystem-in-userspace module regarding the size of the file that has been instructed to be acquired and (b) repeatedly perform a read process in which the file is repeatedly read via the filesystem-in-userspace module based on a comparison between an amount of data acquired by the filesystem-in-userspace module and the size of the file instructed to be acquired.
