Abstract

Disclosed herein are a method of adaptively delivering media based on reception status information from a media client and an apparatus using the same. A media transmission method by a media transmission apparatus may include sending a message, including configuration information for media requested by a terminal, to the terminal, sending a media packet forming the media to the terminal, selecting a media packet having a transport characteristic corresponding to reception quality information for the media packet received from the terminal based on the reception quality information, and sending the selected media packet to the terminal.

Claims

1. A media transmission method by a media transmission apparatus, comprising:

sending a message, comprising configuration information for media requested by a terminal, to the terminal;

sending a media packet forming the media to the terminal;

selecting a media packet having a transport characteristic corresponding to reception quality information for the media packet received from the terminal based on the reception quality information; and

sending the selected media packet to the terminal.

2. The media transmission method of claim 1, wherein the media transmission apparatus owns a plurality of media having different transport characteristics.

3. The media transmission method of claim 1, wherein the media comprise media packets having two or more different transport characteristics.

4. The media transmission method of claim 1, wherein the message comprising the configuration information comprises at least one of information about a transport characteristic of the media and information about a method of sending the reception quality information for the media.

5. The media transmission method of claim 1, wherein the media packet transmitted to the terminal comprises time information about a point of time at which the media packet was transmitted.

6. The media transmission method of claim 1, wherein the reception quality information is measured based on at least one of time information about a point of time at which the media packet was transmitted and information about a time interval in which media packets are received.

7. The media transmission method of claim 1, further comprising receiving a message comprising reception quality information and information about a network status of the terminal, prior to the selecting of the media packet.

8. The media transmission method of claim 7, wherein the message comprising the reception quality information and the information about the network status of the terminal comprises duration for which a reception status of the media packet was measured, a loss rate of the media packet received for the duration, an average interval in which two media packets are received for the duration, a time taken to send the media packet for the duration, a time when the terminal sent a status information message for the duration, a peak bit rate for the duration, and information about buffer fullness remaining in the terminal for the duration.

9. A media transmission apparatus, comprising:

a generation unit for generating a message comprising configuration information for media requested by a terminal;

a transmission unit for sending the generated message and a media packet forming the media to the terminal;

a reception unit for receiving reception quality information for the media packet from the terminal; and

a selection unit for selecting a media packet having a transport characteristic corresponding to the reception quality information,

wherein the transmission unit sends the selected media packet to the terminal.

10. The media transmission apparatus of claim 9, wherein the media transmission apparatus owns at least one of a plurality of media having different transport characteristics and media comprising media packets having two or more different transport characteristics.

11. The media transmission apparatus of claim 9, wherein the message comprising the configuration information comprises at least one of information about a transport characteristic of the media and information about a method of sending the reception quality information for the media.

12. The media transmission apparatus of claim 9, wherein the media packet transmitted to the terminal comprises time information about a point of time at which the media packet was transmitted.

13. The media transmission apparatus of claim 9, wherein the reception quality information is measured based on at least one of time information about a point of time at which the media packet was transmitted and information about a time interval in which media packets are received.

14. The media transmission apparatus of claim 9, wherein the reception unit receives a message comprising the reception quality information and information about a network status of the terminal.

15. The media transmission apparatus of claim 14, wherein the message comprising the reception quality information and the information about the network status of the terminal comprises duration for which a reception status of the media packet was measured, a loss rate of the media packet received for the duration, an average interval in which two media packets are received for the duration, a time taken to send the media packet for the duration, a time when the terminal sent a status information message for the duration, a peak bit rate for the duration, and information about buffer fullness remaining in the terminal for the duration.

16. A method of receiving, by a media reception apparatus, media, the method comprising:

receiving configuration information for the media from a media server;

receiving a media packet that forms the media from the media server;

measuring a reception quality of the media packet;

sending a message comprising information about the measured reception quality to the media server based on the configuration information; and

receiving a media packet having a transport characteristic corresponding to the reception quality from the media server.

17. The method of claim 16, wherein the received media packet comprises time information about a point of time at which the media packet was transmitted.

18. The method of claim 17, wherein the measuring of the reception quality comprises measuring the reception quality of the media packet based on at least one of time information about a point of time at which the media packet was transmitted and information about a time interval in which media packets are received.

19. The method of claim 16, wherein the message comprises duration for which a reception status of the media packet was measured, a loss rate of the media packet received for the duration, an average interval in which two media packets are received for the duration, a time taken to send the media packet for the duration, a time when the terminal sent a status information message for the duration, a peak bit rate for the duration, and information about buffer fullness remaining in the terminal for the duration.
