Abstract

A method and apparatus are provided for a cloud streaming service. A cloud streaming server receives first data corresponding to media source extension (MSE) media from a media source server when a request for content is received from a user device. Then the cloud streaming server creates a first stream by transcoding the first data to a suitable format for processing at the user device, and transmits the created first stream to the user device. Further, the cloud streaming server receives second data corresponding to remaining data except the first data in the content, outputs an execution screen of the content by executing the second data, captures the outputted execution screen, and creates a second stream by encoding the captured screen.

Claims

1. A cloud streaming server comprising:

a media source storage module configured to store first data corresponding to media source extension (MSE) media;

a browser module configured to receive the first data corresponding to the MSE media in content requested by a user device and to store the received first data in the media source storage module; and

a transcoding module configured to create a first stream by transcoding the first data, stored in the media source storage module, to a suitable format for processing at the user device,

wherein the created first stream is transmitted to the user device.

2. The cloud streaming server of claim 1, wherein the browser module is further configured to receive second data corresponding to remaining data except the first data in the content, to execute the second data, and to output an execution screen of the content.

3. The cloud streaming server of claim 2, further comprising:

a screen virtualization processing module configured to capture the outputted execution screen and to create a second stream by encoding the captured screen,

wherein the created second stream is transmitted to the user device.

4. The cloud streaming server of claim 2, wherein the browser module is further configured to process transparently a part corresponding to the first data in the execution screen.

5. The cloud streaming server of claim 1, wherein the first data is a video chuck having a given split length.

6. A user device for requesting content of a cloud streaming server, the user device comprising:

a first stream storage module configured to receive and store a first stream which is created by transcoding first data corresponding to media source extension (MSE) media in the content;

a second stream storage module configured to receive and store a second stream created from second data corresponding to remaining data except the first data in the content;

a first decoding module configured to decode the stored first stream;

a second decoding module configured to decode the stored second stream; and

a playback module configured to create a final output screen through overlay processing of the decoded first and second streams.

7. A cloud streaming service method performed by a cloud streaming server, the method comprising steps of:

receiving first data corresponding to media source extension (MSE) media from a media source server when a request for content is received from a user device;

creating a first stream by transcoding the first data to a suitable format for processing at the user device; and

transmitting the created first stream to the user device.

8. The method of claim 7, further comprising steps of:

receiving second data corresponding to remaining data except the first data in the content;

outputting an execution screen of the content by executing the second data;

capturing the outputted execution screen; and

creating a second stream by encoding the captured screen.

9. The method of claim 8, wherein the outputting step includes processing transparently a part corresponding to the first data in the execution screen.

10. A cloud streaming service method performed by a user device, the method comprising steps of:

receiving a first stream from a cloud streaming server and then storing the first stream, the first stream being created by transcoding first data corresponding to media source extension (MSE) media in content;

receiving a second stream from the cloud streaming server and then storing the second stream, the second stream being created from second data corresponding to remaining data except the first data in the content;

decoding the stored first stream;

decoding the stored second stream; and

creating a final output screen through overlay processing of the decoded first and second streams.
