Abstract

The disclosure relates to a computer-readable recording medium having a program recorded therein for providing network-adaptive content and a related apparatus. The disclosure allows streaming content to be provided to a user terminal in view of a difference in transmission quality of communication networks by analyzing a source address of a signaling message transmitted to the user terminal, identifying the type of a communication network accessed by the user terminal, differently setting media transmission parameters for encapsulation and packetization in accordance with the identified network type, and performing encapsulation and packetization in accordance with the set media transmission parameters.

Claims

1. A computer-readable recording medium having a program recorded therein for providing network-adaptive content, the program comprising steps of:

identifying a type of a communication network connected to a user terminal;

setting media transmission parameters for encapsulation and packetization of multimedia data, depending on the identified network type;

encapsulating the multimedia data into a media processing unit (MPU) by applying the media transmission parameters and packetizing the MPU into a streaming data packet by adding header information, wherein the MPU includes media data corresponding to at least one of audio, video and data and metadata for decoding and playing the media data; and

transmitting the streaming data packet to the user terminal.

2. The computer-readable recording medium of claim 1, wherein the step of identifying the network type includes analyzing a source address of a signaling message transmitted from the user terminal and identifying the network type through the source address.

3. The computer-readable recording medium of claim 2, wherein the signaling message includes at least one of a streaming request message for requesting specific multimedia data and a status feedback information message for periodically notifying a buffer status and a network status.

4. The computer-readable recording medium of claim 1, wherein the media transmission parameters include one or more of an MPU size, a frame rate, and an error correction size.

5. An apparatus for providing network-adaptive content, comprising:

a media processing module configured to encapsulate multimedia data into a media processing unit (MPU) including media data corresponding to at least one of audio, video and data and metadata for decoding and playing the media data; and

a transmission processing module configured to packetize the MPU into a streaming data packet including a header,

wherein the transmission processing module is further configured to identify a type of a communication network connected to a user terminal, and to set media transmission parameters for encapsulation of the media processing module and packetization of the transmission processing module, depending on the identified network type.

6. The apparatus of claim 5, wherein the transmission processing module is further configured to analyze a source address of a signaling message transmitted from the user terminal so as to identify the network type through the source address.

7. The apparatus of claim 6, wherein the signaling message includes at least one of a streaming request message for requesting specific multimedia data and a status feedback information message for periodically notifying a buffer status and a network status.

8. The apparatus of claim 5, wherein the media transmission parameters include one or more of an MPU size, a frame rate, and an error correction size.
