Embodiment Construction

[0028] The example embodiments are within the framework of the delivery of compressed video with RTP, but the invention is not limited to this particular embodiment and can be applied in other frameworks in which streams are delivered continuously in both uncompressed and compressed transfer content.

[0029] exist figure 1 A system according to an embodiment is shown in . Only one terminal is shown, but it is obvious that there may be more than one terminal in the system. Video source 1 is a server or any other video program source. Video source 1 broadcasts a video program in an uncompressed format. The video program is received by a video encoder 2 and a marker insertion device 3 (hereinafter denoted by MID). Video programming includes audio-visual content and may include interactive content such as teletext or closed captions.

[0030] Video encoder 2 compresses uncompressed video into a compressed stream, which is then sent using RTP / RTCP. For example, the video is ...

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 (S1) a streaming content in a first form, receiving (S2) the same streaming content in a second form, receiving (S3) an interactive mark corresponding to a first frame of said content in a first form and sending (S5) said interactive mark synchronized to a second frame of the content received in the second form, the content in said second frame corresponding to the content in said first frame.

Description

technical field [0001] The present invention relates generally to streaming content, and more particularly to delivering interactive markers synchronously with streaming content. Background technique [0002] This section is intended to introduce the reader to various aspects of the invention as described and / or claimed. It is believed that these discussions help to provide the reader with background information to better understand aspects of the present invention. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. [0003] The interactive services mechanism provides synchronization between video programming and applications that can interact with the user in order to provide additional or interactive services to the user. Examples of interactive services are voting applications, interactive games, obtaining information about products, ordering products. Video programming can be live, streamed from...
