Abstract

Provided is a method for transmitting packet-based media data having a header in which an overhead is minimized. A method for media data transmission may comprise the steps of: encapsulating media data to allow a media fragment unit (MFU) header and an M-unit header to share one format; allowing an MMT payload format to include a header field for an operation which is not supported by an RTP header, and transferring the encapsulated media data from a specific entity to another entity; and controlling the transfer of the media data. Therefore, a transmission overhead is minimized, so that it is possible to efficiently transmit media data.

Claims

1. A media data transport method based on a packet having a header with minimized overhead, comprising:

encapsulating media data so that a Media Fragment Unit (MFU) header and an M-Unit (MU) header share one format;

including header fields for operations not supported by an RTP header in an MMT Payload Format and delivering the encapsulated media data from a specific entity to another entity; and

controlling the delivery of the media data.
