Abstract

A method for transmitting a content in a multimedia streaming system is provided. The method includes transmitting, to a client device, control information regarding contents, and transmitting, to the client device, a plurality of segments specified by the control information, where the plurality of segments comprises an initialization segment (IS) and a media segment (MS) and the media data in the plurality of segments are addressed by using relative addressing.

First claim

What is claimed is:

1. A method for receiving a content in a multimedia streaming system, the method comprising:
receiving, from a content server, control information regarding contents; and
receiving, from the content server, a plurality of segments specified by the control information,
wherein the plurality of segments comprises an initialization segment (IS) and a media segment (MS),
wherein the IS includes a moov box and an stsd box, the stsd box including sample description entries required to decode all representations within a representation group, and each sample description entry in the stsd box corresponds to coding information of a media component in each of the representations,
wherein the MS includes a moof box including a sample description index and a mdat box including media data,
wherein a value of the sample description index is an index of one of the sample description entries in the stsd box,
wherein the control information comprises information informing whether a concatenation of the plurality of segments results in a bitstream that conforms to a media format,
wherein the moof box uses movie-fragment relative addressing,
wherein the plurality segments includes track identifiers, and
wherein the track identifiers for a same media content component are identical for each of representations.

2. The method of claim 1 , wherein the information further informs whether the bitstream is playable by a player.

3. The method of claim 1 , wherein the MS comprises a styp box including a value indicating “dash” according to Dynamic Adaptive Streaming over HyperText Transfer Protocol (HTTP) (DASH) standard as a compatible brand.
