AI Technical Summary

Problems solved by technology

In the current processing process, after the shooting of the movie is completed, the movie data is mostly transmitted and projected in a unified manner. The consequence of this is that when the movie is to be displayed on different types of screens, it is difficult to completely match it, even when it is transmitted. During the process, some key frames will be lost, which will cause the movie data to not be displayed normally.
[0005] In summary, there is currently no effective solution to the problem that film data is difficult to maintain integrity and validity during transmission

Embodiment 1

[0082] see figure 1 , figure 2 with image 3 The movie data transmission method proposed in this embodiment specifically includes the following steps:

[0083] Step S101: The data sending end samples the movie data to be transmitted according to the preset time interval to obtain multiple transmission data frames. In the implementation process, generally the movie data to be transmitted is relatively large, and its specific length needs to be determined according to the The shooting time is related to the shooting resolution. Dividing the movie data to be transmitted into multiple transmission data frames is to meet the needs of transmission bandwidth.

[0084] Step S102: The data sending end compares the resolutions of the multiple transmission data frames with the preset screen resolution one by one. In this embodiment, in order to classify and transmit the multiple transmission data frames, the multiple transmission data frames The frame resolution is compared with the...

Embodiment 2

[0125] see Figure 4 , the present embodiment provides a movie data transmission device including:

[0126] The sampling module 1 is used for the data sending end to sample the movie data to be transmitted according to the preset time interval to obtain multiple transmission data frames;

[0127] The resolution comparison module 2 is used for the data sending end to compare the resolution of multiple transmission data frames with the preset picture resolution one by one;

[0128] The key frame extraction module 3 is used for when the resolution of the transmission data frame is greater than or equal to the preset picture resolution, the data sending end records the transmission data frame as a key frame, and saves the key frame locally;

[0129] The normal frame extraction module 4 is used for when the resolution of the transmission data frame is less than the preset picture resolution, the data sending end records the transmission data frame as a normal frame, and saves the ...

Abstract

The invention provides a film data transmission method and device and relates to the technical field of data transmission. The film data transmission method comprises the steps that a data sending endmarks film data as key frames and ordinary frames according to resolutions and carries out different coding, encryption and transmission on the film data, wherein sending time periods are different,and a tail part of a first time period and a head part of a second time period are overlapped, so a data receiving end can obtain the key frames and / or the ordinary frames by sending different requests; and decryption is carried out through application of corresponding keys. The film data is packaged, encrypted and transmitted, so the integrity and validity of the film data in transmission are ensured.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a movie data transmission method and device. Background technique [0002] With the development of science and technology and the improvement of people's living standards, various leisure and entertainment activities are increasingly appearing in people's work and life. For example, traditional handicrafts (such as textiles, embroidery, etc.) have been changed to mechanical automation; can make phone calls, send text messages, etc., and can also surf the Internet); the original black and white TVs have all become color TVs, and can even be controlled and displayed through a touch screen. [0003] In short, great changes have taken place in people's production and life. Especially with the development of film technology, originally only black and white images can be displayed, and can only be displayed on a fixed-size screen. With the development of various technologi...
