Method and system for the embedded sending of data content in a video stream

DESCRIPTION:

FIELD OF THE INVENTION

The invention relates to a method for sending data content and video content from a server via the internet to a user device, wherein the video content is divided into streaming packets which are sent one after the other and displayed on a screen of the user device after receipt on the user device .

State of the art

A method for streaming video content and sending data content is generally known. In the known method, the video content and data content are sent one after the other, the video content being streamed before and / or after sending data content and / or between parts of the data content.

Summary of the invention

An object of the invention is to provide a method of the type described in the preamble in which the content is sent faster than in the known method. To this end, the method according to the invention is characterized in that before the video content is streamed, the data content is divided and the parts are encrypted in the streaming packets and sent together with the video content, wherein during reception of the content on the user device the video and data content are disassembled and the video content is displayed and subsequently lost and upon receipt of the content the parts of the data content are assembled into a whole which is stored in the user device without a of both is filtered. The parts of the data content are preferably securely encrypted in the streaming packets.

In the method according to the invention, the duration of the streaming video is used to send the requested content. The video content and data content are therefore sent simultaneously. By encrypting the two information streams instead of sending them unencrypted one after the other, the content can be better protected against the undesirable separation of the data content and video content.

The invention also relates to a system for sending data content and video content from a server via the internet to a user device where the data content is stored and the video content is displayed and subsequently lost, comprising a system device and a user device, the system device comprising includes for dividing video content into streaming packets, as well as means for streaming video content, and means for sending data content, and wherein the user device comprises means for displaying the video content and means for storing the data content.

With regard to the system, the invention is characterized in that the system device further comprises means for dividing the data content, as well as means for encrypting the data content in the streaming packets, and the user device comprises means for disassembling the video and data content, and means for assembling the parts of the data content into one whole.

Brief description of the drawings

The invention will be explained in more detail below with reference to an exemplary embodiment of the method and system according to the invention shown in the drawings. Hereby shows:

Figure 1 shows a flow diagram in which the method according to the invention is illustrated; and

Figure 2 shows a schematic representation of the system according to the invention.

Detailed description of the drawings

Figure 1 shows a flow diagram in which the method according to the invention is illustrated. A signal 2 is sent from a user device 1, for example via mobile devices, in which data content is requested. This signal is received by a content download server 3 and a video streaming server 4. In the video streaming server 4, the video content is divided into streaming packets and the requested data content is divided into the content download server 3. In a third server 5, the parts of the data content are encrypted in the streaming packets and sent together with the video content according to a content distribution protocol.

The content stream 6 is sent via the internet to the user device 1. After receipt by the user device 1 of the streaming packets with the parts of the data content encrypted therein, the user device sends a confirmation signal 7 to the server from which the packets were sent. If it is found that a part of the data content has not been received because the confirmation signal for that part has not been received, this missing part is encrypted with a further streaming packet of video content.

During the reception of the content stream 6 by the user device 1, the video and data content are taken apart according to a further protocol present on the user device, without either of them being filtered, and the video content is displayed on a screen 8 of the user device . After showing the video content is lost. After receiving all content, the parts of the data content in the user device are assembled into a whole that is stored in the user device.

Figure 2 schematically shows the system according to the invention. The system has a system device 9 and a user device 1. The system device has a content download server 3, which comprises means for dividing the data content, a video streaming server 4, which comprises means for dividing the video content into streaming packets, and a server 5 which comprises means for encrypting the parts of the data content in the streaming packets and sending them to the user device 1.

In the server 5, the streaming packets 11-15 and the parts AD of the data content are encrypted into packets 16-19 according to a protocol present on the server

21. The server 5 also has means for sending the packets via the internet to the user device 1. This user device has means for displaying the video content (of which the screen 8 forms part) and means for storing the data content.

The user device 1 also has means 22 for checking for received packets 16-19 and means for sending acknowledgment signals 7. Of the not received packets, the part of the requested content is requested again (packet 20). Furthermore, the user device 1 has means 23 for disassembling the video and data content according to a further protocol, as well as means for assembling the parts of the data content into a whole.

The video content is immediately displayed on the screen 8 upon receipt and then immediately lost, and the composite data content is stored in the user device 1.

Although in the foregoing the invention has been elucidated with reference to the drawings, it should be noted that the invention is by no means limited to the embodiment shown in the drawings. The invention also extends to all embodiments deviating from the embodiment shown in the drawings within the scope defined by the claims.
