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 non-transitory computer-readable recording medium having a program recorded therein for providing network-adaptive content, the program, executed by a processor including electronic circuits, comprising steps of:

identifying whether types of communication networks, to which each of one or more user terminals connected, are same or different, when multimedia data are respectively sent to the user terminals each connected through one or more communication networks;

setting media transmission parameters used for encapsulation and packetization of the multimedia data, depending on the identified network types of the communication networks to thereby adaptively create the network-adaptive content for the multimedia data, to be provided with the user terminals, considering a media transmission quality of the respective communication networks;

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 non-transitory computer-readable recording medium of claim 1, wherein the step of identifying the network types includes analyzing a source address of a signaling message transmitted from the user terminals and identifying the network types through the source address.

3. The non-transitory 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 non-transitory 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, wherein at least one of the MPU size, the frame rate or the error correction size is determined based on identifying whether the types of the communication networks to which each of the one or more user terminals connected are same or different.

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

a media processing circuit, implemented by a processor, 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 circuit, implemented by a processor, configured to packetize the MPU into a streaming data packet including a header,

wherein the transmission processing circuit is further configured to

identify whether types of communication networks, to which each of one or more user terminals connected, are same or different, when multimedia data are respectively sent to the user terminals each connected through one or more communication networks, and

set media transmission parameters used for encapsulation packetization of the multimedia data, depending on the identified network types of the communication networks to thereby adaptively create the network-adaptive content for the multimedia data, to be provided with the user terminals, considering a media transmission quality of the respective communication networks.

6. The apparatus of claim 5, wherein the transmission processing circuit is further configured to analyze a source address of a signaling message transmitted from the user terminals 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, wherein at least one of the MPU size, the frame rate or the error correction size is determined based on identifying whether the types of the communication networks to which each of the one or more user terminals connected are same or different.
