Abstract:
PURPOSE: A method for transmitting and receiving complex media contents in a multimedia system and a device thereof are provided to efficiently generate the complex media contents including multimedia data and transmit/receive the complex media contents. CONSTITUTION: A multimedia source M-unit input unit(401) receives M-Unit which is a bundle of multimedia data of various kinds. A multimedia source identification unit(403) assigns asset ID to the bundle of a M-Unit. A multimedia source storage unit(405) stores generated ASSETs. A transmission unit(407) transmits the ASSETs through a determined communication network. A control unit(409) collects media fragment units(MFU) of various kinds provided from at least multimedia data. The control unit comprises the MFUs as the M-Unit.

Abstract:
PURPOSE: A device for transceiving complex multimedia data is provided to efficiently transceive complex contents by efficiently notifying a position of an MFU(MMT Fragment Unit) or a transmission point, an MFU type, and a kind of the MFU through an MFU header. CONSTITUTION: If the number of multimedia composing an MFU package or an MFU asset is not greater than a threshold value, a device generates a first MFU header(502,510). If the number of multimedia is greater than the threshold value and the number of similar multimedia is greater than a predetermined threshold value, the device generates a third MFU header(503,504). If the number of the similar multimedia is not greater than the predetermined threshold value, the device generates a second MFU header(520). The device generates an MFU by using actual multimedia data and the headers(505).

Abstract:
PURPOSE: A method and an apparatus for improving quality of a multimedia streaming service based on a hypertext transfer protocol are provided to rapidly output first screen in a low speed beginning environment using a preview method. CONSTITUTION: The priority information and range information of media are recorded in a media technical engineer file. The priority information of the NAL unit header is recorded in the media technical engineer file. Data is re-constructed according to the priority of media. The range information of the re- constructed stream is recorded in the media technical engineer file. A preview screen is provided to users since the media technical engineer file is partially transmittable. The partial transmission and reception of a single media stream piece is performed using a media technical engineer file.
Abstract:
PURPOSE: A method and a device for transmitting user information between terminals in a broadcasting streaming service are provided to transmit user set information set by previous terminal and consumer present condition of contents the change terminal to a changed terminal, thereby providing the same contents consumer environment to different terminal. CONSTITUTION: Changed user information stores a user profile if information is changed while a first terminal(110) consumes the contents. A terminal consuming the contents is change form a first terminal to a second terminal(120). The second terminal receives the user profile. The second terminal comprises a continuous consumption stage which continuously consumes contents consume-completed in the first terminal.
