Embodiment
The present invention is described in further detail below by embodiment and with reference to accompanying drawing.
As shown in figure 1, the present invention includes a kind of four channel images coding, transmission, decoding system and method, the system includes
Video camera 1, image encoding system 2, image delivering system 3, image decoding system 4 and display driving 5, wherein to the volume of image
Code, transmission, decoding can have many different forms combination, or decomposite other forms again according to this several form, and it is former
It is then the separate image information in four tunnels can be compressed in a standard channel to be transmitted, its five-star application is
The true 3D radio and television or 2k digital movie datas for possessing four road independent signals are encoded, transmitted and decoded.This is
System principle can also amplify ultra high-definition UHD 4k x 2k（4,096 x 2,160 or 3,840 x 2,160 or similar）Even more
High-resolution application, its coding and decoding principle is identical, and the channel that simply bandwidth must be used bigger is transmitted.
The specific method that four road signals are encoded, decoded can use traditional mode, can also use some
The mode of exploitation, such as SOC including the integrated DTMB/DTMB-A/AVS+/H.264/H.265 researched and developed etc..
The present invention has following application：
1st, as the coding of completely self-contained common HDTV or the 2k digital movie data in four tunnels, transmission and decoding；Now
Application be that four road HDTV data-signals or 2k digital movie data information are transmitted in a standard channel.This four road HDTV
Data-signal or 2k digital movie datas information can be independent of each other, take four tunnels using high compression rate H.265
Signal Compression together, is transmitted in a standard channel, and application now is passed respectively relative to four common road signals
Defeated main beneficial effect is that four road signals occupy a standard channel jointly, realizes the abundant profit of high frequency signal transmission
With greatling save the occupancy of frequency spectrum, belong to green effect.
2nd, conciliate as the coding of two sets of dual image 3D radio and television or 2k digital movie datas independent of each other, transmission
Code；Application now is that two sets of independent " two-way is full HD " dual image 3D signals are transmitted in a channel, or four tunnels are only
The 3D signals of vertical " left-right format " or " top-down format ".
3rd, as the coding of a set of true 3D radio and television or 2k digital movie datas, transmission, decoding.
4th, other combinations are carried out according to above 1 and 2.
5th, the transmission more than can also use H.264 standard be compressed, but be due to that compression ratio is low, whole efficiency is low
It is compressed in using H.265 standard.
Its superlative degree application is specifically described below：
It is not simply to be imaged with twin camera or twin-lens as shown in Fig. 2 being such as intended to carry out true 3D shootings for a scenery
Machine, but use upper left, upper right, bottom left, four video cameras of bottom right, so obtain by four different directions for same object
Intake generate four independent images, then follow the steps below：
Method 1：According to shown in Fig. 3, four independent image informations are subjected to synthesis computing according to the dependency relation shown in Fig. 5 and compiled
Code is one i.e. by four independent image Data Synthesis, then transmits, is decoded in receiving terminal, feeding display driving, aobvious
Show drive part, can realize that true 3D is shown using any true 3D Display Techniques, such as the true 3D realized using laser system
Display.The focusing on of this method has first carried out synthesis computing.
Method 2：According to shown in Fig. 4, four independent image data are compressed respectively, then carry out mixed transport, reception,
Decoding, then by the four independent image data obtained after decoding according to the dependency relation progress synthesis operation coding shown in Fig. 5, general
Four independent image Data Synthesis are one, are then fed into display driving, in display driving part, can be shown using any true 3D
Show technology to realize that true 3D is shown, such as the true 3D realized using laser system is shown.Carried out after the focusing on of this method
Synthesize computing.
Situation when system is to carry out four independent HDTV transmission using single channel, system situation such as Fig. 6 now
Shown, i.e. four individual data signals of transmitting terminal carry out coded combination together, by transmitting, receiving the decode, in the buffer
Four original road independent image data are restored, the application of this four tunnels view data can be combined according to foregoing principle.
Above example is merely to illustrate the preferred embodiment of the present invention, but the present invention is not limited to above-mentioned embodiment party
As that can have being applied in combination for a variety of situations under certain conditions in formula, system, in protection domain；It is general in the field
In the knowledge that logical technical staff possesses, any modification for being made within the spirit and principles in the present invention, equivalent substitute and
Improve etc., it all should cover within the scope of claimed technical scheme of the invention.
