detailed description

In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

The current basic business interaction process of video playback is as follows:

1. The browser downloads the player plug-in from the video website;

2. Browse and select the video you want to play;

3. Request the description information of the video, including video file size, duration, download address, etc.;

4. Request the advertisement video description information associated with the video, including video advertisement duration, download address, etc.;

5. Download and play the advertising video;

6. Download and play normal video.

Among them, the operation of downloading the player plug-in in step 1 is only for viewing videos in the browser mode, and this process is not required when using the APP.

Since the above-mentioned interactive process all uses the HTTP protocol, and for a specific video website, each request and response HTTP message has certain characteristics, so when the home gateway intercepts the request message sent by the client to the video website server According to the characteristics of the request message, an effective method of pre-authentication can be used to control the sending of the response message of the client, so as to achieve the purpose of video advertisement filtering. The method is designed based on the HTTP transmission protocol for the interaction between the client (terminal) and the video server (the first network side server) when playing the video. The specific method is as follows:

As shown in Figure 1 and Figure 2, a video advertisement filtering method provided by the embodiment of the present invention is applied to a gateway, including:

A. Obtain the first hypertext transfer protocol HTTP request message sent by the terminal, the first HTTP request message includes the network protocol IP address or uniform resource locator that the terminal requests to access the first network side server through the gateway URL address;

B1. Determine whether the IP address or the URL address is included in the first filtering address list according to the first HTTP request message;

C1. When the IP address or URL address is included in the first filtering address list, send a response message to the terminal that includes the download address of the video player for filtering advertisement playback;

and / or

B2. According to the first HTTP request message, determine whether the IP address or the URL address is included in the second filtering address list;

C2. When the IP address or URL address is included in the second filtering address list, intercept the video information request returned by the first network side server; delete or modify the advertisement video description information in the video description information request, and obtain The video description information played by the filtered advertisement is sent to the terminal.

After step C1 also include:

receiving a second HTTP request message sent by the terminal, the second HTTP request message including the network protocol IP address or URL address of the server on the second network side requested by the terminal to access the second network side server through the gateway; so that the The terminal requests from the second network side server to download a video player for filtering advertisements through the gateway.

After receiving the second HTTP request message sent by the terminal, the method further includes: returning a redirection message with a status code of 302 to the terminal.

In the embodiment of the present invention, the gateway forwards the second HTTP request message sent by the terminal to the second network side server, and forwards the description information of the video player for filtering advertisement playback sent by the second network side server to the terminal.

Modifying the advertisement video description information in the video description information request in step C2 includes:

Modifying the advertisement video description information in the video description information request to a response message whose status code is 200OK and whose body content is empty;

Or, modify the advertisement video description information in the video description information request to substitute video description information whose playback duration is shorter than a threshold.

Before modifying the advertisement video description information in the video description information request to substitute video description information whose playback duration is shorter than the threshold, the method further includes: returning a redirect message with a status code of 302 to the terminal.

Wherein the first way, step A is combined with steps B1 and C1, which can be called the way of replacing the video player. When the gateway receives the download player request message (the first HTTP request message) from the terminal, it will point to the original video website (the first network side server) player downloader by replying with a redirection message with a status code of 302. The address is redirected to another new address (the second network side server), and the player stored in this address is a replaced video player without advertisement playback function.

The second way is the combination of step A and steps B2 and C2, which can be called the method of video advertisement description information control. When the gateway intercepts the request for the advertisement video description information of the player, it returns a response report with a status code of 200 OK. Because the terminal cannot obtain the description information of the video advertisement, the player will automatically skip the playback of the video advertisement and directly play the normal ordinary video. After the gateway intercepts the player's video (advertisement) description information request, it obtains the original video (advertisement) description information from the destination server through HTTP proxy, deletes or modifies the advertisement video content in the original playlist, and then returns to the player. device, so as to achieve the purpose of removing advertisements. When the gateway intercepts the download advertisement video request sent by the player, it returns a redirect message with status code 302, and replaces the original advertisement video with an alternative video with a short playing time, such as a short video of 1 second, so as to achieve fast jumping. The effect of playing through the video ad.

The method provided by the embodiment of the present invention can also update the first filtering address list and the second filtering address list according to a predetermined rule.

The first filtering address list and the second filtering address list may be in a combined form or in an independent form.
