the audio renderer configured to render the decoded audio data.

7. The media playback apparatus of claim 6 , wherein the chunk data is compressed data before being decoded and the audio data synchronized with the chunk data is decoded and decompressed data.

8. The media playback apparatus of claim 6 , wherein the audio renderer is implemented by an audio application program interface (API) supported by the web browser.

9. The media playback apparatus of claim 1 , wherein the audio synchronizer buffers the separated audio data in synchronization with the restored video based on the time information provided on the chunk data basis, and decodes the buffered audio data to restore and output audio.

10. The media playback apparatus of claim 9 , wherein the audio synchronizer comprises:

a buffer controller configured to buffer the separated audio data in synchronization with the chunk data;

an audio decoder configured to decode the buffered audio data based on a script which is configured to be parsed by the web browser; and

an audio renderer configured to render the decoded audio data.

11. The media playback apparatus of claim 10 , wherein the chunk data is compressed data before being decoded and the audio data synchronized with the chunk data is data before being decoded by the audio decoder.

12. The media playback apparatus of claim 1 , wherein the decoder embedded in the web browser is a video tag player supported by a language for presenting content on world wide web, and the receiver, the container and the audio synchronizer are implemented by a programming language of world wide web.

13. The media playback apparatus of claim 12 , wherein the programming language of world wide web is downloaded from the media service apparatus to the media playback apparatus.

14. A media service apparatus for transmitting media data to a media playback apparatus, the media service apparatus comprising:

a module storage configured to store a script converter to reproduce the media data on a web browser of the media playback apparatus; and

at least one processor configured to implement:

a module transmitter configured to transmit the script converter to the media playback apparatus in response to a connection between the media service apparatus and the media playback apparatus being established;

a packetizer configured to packetize the media data to generate a transmission packet; and

a web server configured to establish the connection and transmit the transmission packet to the media playback apparatus in response to a request from the media playback apparatus,

wherein the script converter is configured to receive the transmission packet through the connection, package video frames included in the transmission packet together with a unit number representing a number of frames and convert the frames into chunk data wherein the chunk data is obtained by packaging video frames with the unit number or packaging video frames and audio with the unit number, and output audio data included in the transmission packet in synchronization with the chunk data based on time information on a time point at which the chunk data is decoded and outputted by a media restorer installed in the media playback apparatus.

15. The media service apparatus of claim 14 , wherein the script converter is code written in a programming language of world wide web which is configured to be parsed by the web browser.

16. The media service apparatus of claim 14 , wherein the time point at which the chunk data is rendered by a renderer in the media playback apparatus corresponds to a start portion of the chunk data.

17. The media service apparatus of claim 14 , wherein the script converter is configured to output the audio data in synchronization by decoding the audio data included in the communication packet to restore audio, and outputting the restored audio in synchronization with the chuck data based on the time information provided on the chunk data basis.

18. The media service apparatus of claim 14 , wherein the script converter is configured to output the audio data in synchronization by buffering the separated audio data in synchronization with the chunk data, decoding the buffered audio data based on a script which is configured to be parsed by the web browser, and

rendering the decoded audio data.

19. The media service apparatus of claim 14 , wherein the chunk data is compressed data before being decoded and the audio data synchronized with the chunk data is data which is decoded in the media playback apparatus and decompressed.

20. A media playback apparatus for synchronously reproducing video and audio on a web browser, the media playback apparatus comprising at least one processor to implement:

a receiver configured to receive media data generated in a media service apparatus using a communication protocol which supports web services;

a data separator configured to separate the received media data into first media data and second media data;

a container configured to package frames constituting the first media data together with a unit number representing a number of frames and convert the frames into chunk data wherein the chunk data is obtained by packaging video frames with the unit number or packaging video frames and audio with the unit number;

a media restorer configured to restore first media by decoding the chunk data by a decoder embedded in the web browser, and provide time information on a time point at which the restored first media is outputted on a chunk data basis when the restored first media is outputted; and
