Embodiment 1

[0067] Such as figure 1 As shown, Embodiment 1 of the present invention provides a video frame stream processing method, and the processing method includes the following steps:

[0068] S1. The video server collects the static picture images of each video frame in the video frame stream requested by the terminal device; according to the request of the terminal device, the video server receives the request, processes the requested file, and collects each frame in the requested video frame stream. A static image of a video frame, where the video frame is a single static image.

[0069] S2. Encoding the position of the static picture images in the video frame stream; each of the static picture images is numbered according to the playing time sequence, and the position numbers cannot be disordered.

[0070] S3. Perform blurring processing on the static picture image to obtain a blurred image and a difference image; specifically, perform blurring processing on each of the static p...

Embodiment 2

[0076] Such as figure 2 As shown, Embodiment 2 of the present invention is further limited on the basis of Embodiment 1. In step S1, the specific method for the video server to collect the static image of each video frame in the video frame stream requested by the terminal device includes:

[0077] S1-1: Pre-store in the video server a list of correspondences between the device information of the terminal device and the viewing time period of the video frame stream;

[0078] Since some videos are only for certain terminal devices to watch or download, therefore, confirm the video frame stream played according to the device information, for example, the first terminal device can only watch the 10th-20th minute, and the second terminal device can only watch the 5th minute -15 minutes.

[0079] S1-2: Collect the device information of the current terminal device, and search the time period that the current terminal device can watch in the video frame stream in the corresponding ...

Embodiment 3

[0092] Such as Figure 5 As shown, on the basis of Embodiment 1, Embodiment 3 of the present invention not only blurs the image of the video frame, but also processes the video frame to realize secondary encryption of the video. The processing method also includes:

[0093] S6. The video server inserts several pop-up windows into the video frame stream requested by the terminal device, the display interface of the pop-up windows is provided with decoding questions, and at the same time, the video server stores information corresponding to the decoding questions Decode the answer, and according to the encryption algorithm and encryption key pre-negotiated with the terminal device, encrypt the decoded answer to form an encrypted attachment, and send it to the terminal device; the pop-up window matches the video frame requested by the terminal device in the form of a video frame The video frames in the stream are associated, and decoding questions are inserted into the video fra...

Abstract

The invention provides a processing method of a video frame stream, a video server and a terminal device. The processing method comprises the following steps of collecting, by the video server, a static menu image of each video frame in the video frame stream which is requested by the terminal device; coding the position, in the video frame stream, of the static menu image; carrying out fuzzy processing on the static menu image, so as to obtain a fuzzy image and a difference image; according to an encryption algorithm and an encryption key which are previously negotiated with the terminal device, encrypting the obtained difference image, and generating an encrypted file; transmitting the video frame stream of which the image is processed and the generated encrypted file to the terminal device. According to the processing method, the video server and the terminal device, which are provided by the invention, the static menu image of the video frame is subjected to the fuzzy processing to obtain the fuzzy image and the difference image; the difference image is encrypted; other persons are prevented from directly checking or obtaining a clear image of a video frame image; the effective encryption on a video is realized; the transmission safety of the video is improved.

Description

technical field [0001] The invention relates to the technical field of multimedia security, in particular to a video frame stream processing method, a video server and a terminal device.
