Referring to Fig. 2, being the flow chart for the cinematic data processing method that first embodiment of the invention provides.The film number
It is applied to server according to processing method, detailed process shown in Fig. 2 will be described in detail below.
Step S101 obtains the key frame and normal frames of pending cinematic data.
Wherein, the key frame is the frame for carrying the critical data in cinematic data, and the normal frames refer in addition to institute
State other data frames other than key frame.
The key frame and the normal frames are encrypted step S102, and corresponding generation Target key frames and target are general
Logical frame.
As an implementation, the key frame is encrypted based on the first coding mode, generation carries first
The Target key frames of encryption information；The normal frames are encrypted based on the second coding mode, generation carries second
The target normal frames of encryption information, wherein first coding mode and the encrypted data of the second coding mode
Type is identical encryption type.Key frame and the normal frames are encrypted respectively by using different encryption modes, into one
Step improves the safety of data, and key frame and the normal frames are encrypted as same type by different encryption modes,
So that transmitted data can be correctly validated receiving terminal, further such that in the safety for improving data transmission
While, the accuracy of identification is improved, for example, the encryption type can be Boolean, can also be numerical value, such as numerical value area
Between.Beautiful such as the encryption type can be A classes, can also be that B classes or the encryption type are 0, can also be described
Encryption type is 1 etc..Here, being not especially limited.
Wherein, first coding mode can be ASCII character, can also be region-position code.Here, being not especially limited.
Wherein, second coding mode can also be ASCII character, can also be region-position code.But first coding mode and institute
It cannot be identical coding mode simultaneously to state the second coding mode.By select different coding pattern to key frame and normal frames into
Row encryption, can effectively improve the safety of data.
As an implementation, the first data packet for carrying the key frame is obtained, the first coding mode will be based on
Encrypted first encryption information is packaged in the packet header of first data packet；Obtain the second data for carrying the normal frames
Packet；The packet header of second data packet will be packaged in based on encrypted second encryption information of the second coding mode.
The Target key frames and the target normal frames are sent to reception terminal by step S103 based on preset channel.
Wherein, the reception terminal can be cinematic movie presentation device, can also be server.Here, being not especially limited.
As an implementation, the Target key frames and the target normal frames are sent simultaneously based on preset channel
To reception terminal.By sending the key frame and normal frames simultaneously so that in the process of acquisition between key frame and normal frames
In there is no time interval, and then accelerate it is described reception terminal obtain receive cinematic data time.
As another embodiment, prefixed time interval is based on by the Target key frames and the target normal frames base
It is sent to reception terminal in preset channel.A key frame and normal frames are sent by being spaced preset time so that front and back two
Existence time buffers between secondary transmitted key frame and normal frames, such as it is front and back refer to key frame transmitted by first time twice with
Normal frames and second transmitted key frame and normal frames, wherein do not sending any number between second for the first time
According to, and then the reception terminal each received key frame and normal frames is made can to have enough processing times to be solved
Analysis.Wherein, the time interval can be 2 milliseconds, can also be 1 millisecond.Here, being not especially limited.
As an implementation, the Target key frames are sent to reception terminal by the first channel；By the mesh
Mark normal frames are sent to reception terminal by second channel.
Wherein, first channel and the second channel are different channels.By selecting different channels to send different numbers
According to further improving the safety of data and the validity of data.And by the way that key frame and normal frames are passed through difference
Channel is transmitted, and different types of data frame is identified so as to improve, and so that receiving terminal need not receive
To after data frame, classify to the data frame received.For example, when reception terminal receives the data of the first channel, then
It is Target key frames that received data, which can be directly defaulted as, and it is target normal frames to be received by second channel, is carried
While high efficiency of transmission, the processing pressure for receiving terminal is reduced.
