APPARATUS AND METHOD FOR TRANSCEIVING A STREAMING SERVICE

WIPO Patent Application WO/2012/008792

A3

The present invention relates to an apparatus and method for transmitting and receiving a streaming service. The apparatus and method for transmitting and receiving a streaming service involve using a lightweight multimedia file suitable for HTTP streaming. An ISO file that is created by a non-interleaved storage method unsuitable for an HTTP streaming service can be converted, using an HTTP hint track, into a file of an interleaved storage method suitable for an HTTP streaming service. The ISO file may contain multimedia tracks for supporting multiple bit rates and resolutions. Chuck data of media tracks, which provide multiple multimedia qualities, can be efficiently acquired, and the acquired chuck data is stored in an interleaved method, thereby generating a lightweight ISO file suitable for an HTTP streaming service.
