Abstract

The present invention concerns a device and a method for inserting an interactive mark in a streaming content, said method comprising the steps of receiving a streaming content in a first format, receiving the same streaming content in a second format, receiving an interactive mark, corresponding to a first frame of said content in a first format and sending said interactive mark synchronized to a second frame of the content received in the second format, the content in said second frame corresponding to the content in said first frame.

First claim

The invention claimed is:

1. A method, at a mark insertion device, for inserting an interactive mark in a streaming content, said method comprising, at said device, the steps of:
receiving a streaming content in an uncompressed format from a first source device;
receiving said streaming content in a compressed format from a second device and transported over RTP;
receiving from a third device an interactive mark corresponding to a first frame of said streaming content in the uncompressed format;
identifying a second frame of said streaming content in the compressed format, said second frame being the one which content corresponds to the content in said first frame; and
sending said interactive mark in an RTP packet having a timestamp that corresponds to the one of said second frame.

2. The method according to claim 1 , wherein said interactive mark is appended to said second frame.

3. The method according to claim 1 , wherein said interactive mark is sent in a RTP packet different from said second frame.

4. The method according to claim 1 , wherein said content is a video content.

5. A device comprising:
a communicating module configured to receive streaming content from a first device in an uncompressed format, receive said streaming content from a second device in a compressed format and transported over RTP and send said streaming content in a compressed format, and
a marking module configured to, on reception of an interactive mark from a third device corresponding to a first frame of said streaming content in the uncompressed format, identify a second frame of said streaming content in the compressed format, said second frame being the one which content corresponds to the content in said first frame, and send said interactive mark in an RTP packet having a timestamp that corresponds to the one of said second frame.

6. A computer device comprising:
a non-transitory memory; and
a processor configured to execute the steps of the method according to claim 1 .

7. The device according to claim 5 , wherein said interactive mark is appended to said second frame.

8. The device according to claim 5 , wherein said interactive mark is sent in an RTP packet different from said second frame.

9. The device according to claim 5 , wherein said content is a video content.
