Processing method to be implemented upon the occurrence of an expression switch in http streaming

A method of transmitting HTTP streaming, comprising:

• transmitting a media information file that stores information on a plurality of segments for transmission target contents,
• wherein the media information file includes a plurality of first elements, streaming target contents being divided into the plurality of elements in a unit of time, wherein the plurality of first elements have different representation depending upon at least one of bit rate and resolution.

A method of transmitting HTTP streaming, comprising:

• transmitting a media information file that stores information on a plurality of segments for transmission target contents,
• wherein the media information file comprises a first media information file that stores information on segments when representation switching does not occur and a second media information file that stores information on segments when representation switching occurs.

A method of receiving HTTP streaming transmission, comprising:

• receiving a media information file, the media information file storing information on a plurality of segments for reception target contents, the media information file storing first information on segments when representation switching does not occur and second information on segments when representation switching occurs, and the first information on segments when representation switching does not occur being distinguished from the second information on segments when representation switching occurs;
• and
• sequentially receiving and playing segments for reception target contents on the basis of the media information file, the segments for reception target contents being received and played on the basis of the first information when representation switching does not occur, and the segments for reception target contents being received and played on the basis of the second information when representation switching occurs.
