The bandwidth of the physical channel of firmware data is transmitted, also, the transmission range of the coaxial cable is also far, it might even be possible to reach hundreds of
Rice.Video data is one-way transmission in the video data transmission channel, and video data is usually from the first equipment to second
What equipment was transmitted.When it is implemented, the first equipment can be DVR (Digital Video Recorder, HD recording
Machine) perhaps the second equipment of video synthesis platform can be the video display devices such as display screen or display matrix, this
Sample, video data are generally transmitted from DVR or video synthesis platform to video display devices, are filled without being shown by video
It sets to DVR or video synthesis platform and is transmitted.
In the following, first corresponding to be illustrated for the firmware data transmission method of the first equipment.
Referring to Fig. 1, the flow chart of firmware data transmission method provided in an embodiment of the present invention is shown in figure.This method can
With the first equipment being applied in digital monitor system, the second equipment in the first equipment and digital monitor system passes through video counts
It is connected according to transmission channel.As shown in Figure 1, this method comprises the following steps:
Step S101 reads firmware data, wherein the firmware in firmware data including the second equipment upgrade required
Data.
Wherein, the CPU integrated and the first video processing module, the processing of the first video be can have in the first equipment
Module has video processing function.Specifically, firmware data can be read into the cache of its internal CPU by the first equipment
In.
Firmware data is sent to the second equipment by video data transmission channel by step S102, so that the second equipment root
Firmware is upgraded according to firmware data.
When it is implemented, can have CPU, the second video processing module and storage unit, CPU and second in the second equipment
Video processing module integrates, and storage unit is connect with CPU, and the second video processing mold has video processing function.Second
Equipment can receive firmware data by its internal mono- frame frame of CPU or a place, and then the firmware data is written online
Into storage unit, make original firmware data in firmware data replacement storage unit, this completes fixed datas
It updates, so as to complete the upgrading of firmware corresponding with the firmware data.
As can be seen that the upgrading of firmware is not needed through dedicated transmission firmware in the second equipment in the embodiment of the present invention
The physical channel of data realizes, directly the video by being originally used for transmitting video data between the first equipment and the second equipment
Data transmission channel does not need in addition to be routed, therefore updating operation implements very convenient, while also reducing upgrading
Cost.Further, since the bandwidth in video data transmission channel generally can achieve 1.5Gbps, it is much larger than and uses in the prior art
Therefore bandwidth in the physical channel of transmission firmware data compared with prior art, is used for transmission firmware data in the present invention
Time will greatly shorten, and the efficiency of transmission of firmware data will greatly improve, correspondingly, the time spent needed for firmware upgrade
Also can correspondingly shorten, to enormously simplify the upgrade maintenance of firmware.
In the present embodiment, before firmware data is sent to the second equipment by video data transmission channel, this method
Can also include:
Firmware data is written to the video data storage region of the first equipment.
At this moment, firmware data is sent to the second equipment by video data transmission channel, comprising:
Firmware data in video data storage region is sent to the second equipment by video data transmission channel.This implementation
In example, a video output buffer can have in the first video processing module, there are video counts in the video output buffer
According to memory block, which, which generally defaults, is used to store video data.After obtaining firmware data, the first equipment can be by firmware
Data are read into the cache of its internal CPU, then, firmware data in the cache of CPU can with a frame frame or
One place of person is written to video data storage region, before firmware data is written to the region, has in video data storage region
There are some invalid data, after firmware data is written to the region, firmware data will replace these originally invalid numbers
According to since video data storage region is usually to default to be used to store video data, if other kinds of data are inserted the area
In domain, then other kinds of data can also be defaulted as video data.Therefore, after firmware data is inserted in the region, firmware
Data will be defaulted as video data, i.e. firmware data is successfully pretended for video data, therefore in video data storage region
The firmware data of disguise as video data can be transmitted successfully in video data transmission channel, and be finally sent to second
Equipment, so that the second equipment is upgraded according to the firmware data.
It should be noted that horizontal blanking data and field blanking data can also be stored in video data storage region, at this point,
Firmware data in video data storage region is sent to the second equipment by video data transmission channel, so that the second equipment root
Firmware is upgraded according to firmware data, comprising:
Using the horizontal blanking data and field blanking data in video data storage region, generate comprising in video data storage region
Firmware data video data packet；
Video data packet is sent to the second equipment by video data transmission channel, so that the second equipment is from video data
Firmware data is extracted in packet, and firmware is upgraded according to firmware data.
Specifically, before firmware data is written to video data storage region, as shown in Fig. 2, video data storage region
Interior to have horizontal blanking data field, field blanking data field and effective row data field, horizontal blanking data field has horizontal blanking data, and field disappears
Hidden data field has field blanking data, and effective row data field is some invalid data.Wherein, horizontal blanking data and field blanking number
There are the data for synchronous and timing in.As shown in figure 3, after firmware data to be written to effective row data area, firmware number
According to these originally invalid data will be replaced, to realize the camouflage of firmware data, also, horizontal blanking data, field blanking data
A video data packet can be generated with firmware data three, which can export from video output buffer, then should
Video data packet can be sent to the second equipment through video data transmission channel, in entire transmission process, horizontal blanking data and
It can guarantee that video data packet is smooth in video data transmission channel for synchronous and timing data in field blanking data
Transmission.For the second equipment, internal CPU can receive video data packet with a frame frame or a place, and from the view
Frequency extracts the firmware data of disguise as video data in, while abandoning horizontal blanking data and field blanking data, finally will
The firmware data is written in storage unit online, makes original firmware data in firmware data replacement storage unit, in this way
The update of fixed data is completed, just so as to complete the upgrading of firmware corresponding with the firmware data.
Further, in above-described embodiment, the firmware data in video data storage region is being passed through into video data transmission
Channel is sent to before the second equipment, and this method can also include:
Digital serial interface SDI stringization is carried out to the firmware data in video data storage region；
Firmware data in video data storage region is sent to the second equipment by video data transmission channel, comprising:
The firmware data after SDI stringization will be carried out in video data storage region is sent to the by video data transmission channel
Two equipment.
In the present embodiment, it is defeated from video that the firmware data in video data storage region usually passes through a parallel output interface
It is exported in buffer out, the firmware data exported at this is parallel data, and the data transmitted in video data transmission channel
It needs to need to carry out SDI string to firmware data for serial data, therefore before by firmware data inputting video data transmission channel
Change.Wherein, which can be realized by a SDI serializer.When it is implemented, the SDI serializer can be one
SDI stringization chip, which can integrate in the first equipment, in the SDI by firmware data from SDI stringization chip
After input port input, parallel firmware data can be converted to serial digital signal by SDI stringization chip, and according to SDI
Signal standards is inserted into time synchronizing signal into digital signal, then exports the digital signal from the SDI of SDI stringization chip
Port output, this completes the SDI stringization processes of firmware data, then again pass through the firmware data after SDI stringization
Video data transmission channel is sent to the second equipment.
It should be noted that SDI stringization chip can also be located at video data and pass other than being integrated in the first equipment
Defeated channel is close to that one end of the first equipment, in this way, the first equipment first exports parallel firmware data, then firmware data is passed through
SDI stringization chip is transmitted by video data transmission channel again after completing SDI stringization.
Since the first equipment is serial digital signal to the second equipment by video data transmission channel transfer, second
Equipment can not directly upgrade the second equipment according to the digital signal, if desired upgrade to firmware, then it is first right to need
The digital signal carries out SDI and unstrings.Wherein, which can be realized by a SDI deserializer.When it is implemented,
The SDI deserializer can unstring chip for a SDI, and the SDI chip that unstrings can integrate in the second equipment.For the second equipment
For, for received digital signal after the input of the SDI input port of SDI deserializer, SDI unstrings chip can will be serial
Digital signal is converted to parallel digital signal, and time synchronizing signal is removed from the parallel digital signal, final
To firmware data, and by the firmware data from SDI unstring chip SDI output port export, this completes SDI to unstring
Journey.
If the firmware data in video data storage region is only sent to the second equipment by the first equipment, then unstringing through SDI
Only there is firmware data, the second equipment directly reads the data and writes the data into storage unit just in the data obtained afterwards
Firmware can be upgraded.If the view that the first equipment will be made of horizontal blanking data, field blanking data and firmware data three
Frequency data packet is sent to the second equipment, then in the data obtained after SDI unstrings while having horizontal blanking data, field blanking number
According to and firmware data, at this moment, the second equipment will only extract firmware data, while abandon horizontal blanking data and field blanking data, most
Firmware is upgraded according to firmware data afterwards.
It should be noted that SDI unstrings chip can also be logical positioned at video data transmission in addition to being integrated in the second equipment
Close to that one end of the second equipment, the serial data-signal exported in this way by video data transmission channel can be solved first through SDI in road
Serial core piece completes SDI and unstrings process, is then transmitted further to the second equipment.
It should be noted that the first equipment is other than it can be DVR or video synthesis platform, or other
Sdi signal decoding apparatus, the second equipment is other than for video display devices, or other sdi signal code devices,
First equipment and the second equipment are specially which kind of device in digital monitor system can determine according to the actual situation, this implementation
Example does not do any restriction to this.
In above-described embodiment, the firmware data that the second equipment obtains is not necessarily accurate, therefore also needs to obtain the second equipment
The accuracy of firmware data verified.
In order to judge the second equipment obtain firmware data accuracy, can to firmware data carry out and verify.Specifically
Ground, before the video data storage region that firmware data is written to the first equipment, this method can also include:
To the data progress and operation in firmware data, operation result is obtained, using operation result as verification data；
The addition verification data into firmware data；
Firmware data is written to the video data storage region of the first equipment, comprising:
Firmware data added with verification data is written to the video data storage region of the first equipment.
The specific implementation process with verification is described in detail below.
If including 4 data in firmware data, respectively 1,2,3,4 can be to this four data progress and operations, i.e.,
This four data are added, obtain 10, which is to verify data.Then the verification data are added to initial firmware number
In, it at this moment will will include five data in firmware data.Then, this five data are successively solved through SDI stringization, transmission and SDI
String process is received by the second equipment, and the second equipment can be carried out and be transported to the first four data in received five data
Calculation, obtains an operation result, the 5th data for then getting the operation result with it, such as 10 are compared, if two
Person is identical, then the firmware data for illustrating that the second equipment obtains is very accurate, is updated then according to the data to firmware,
If the two is different, illustrates the firmware data inaccuracy that the second equipment obtains, can be set again from the first equipment to second at this time
Standby transmission firmware data, until the acquisition of the second equipment is that accurate firmware data again upgrades firmware.
It should be noted that may be used also except except through verification of the mode with verification to realize firmware data accuracy
To be verified using even-odd check or other modes well-known to those skilled in the art, specific verification mode can root
It is determined according to actual conditions, the present embodiment does not do any restriction to this.

The unstring chip of chip 4 of SDI is not limited to this, and can specifically be determined according to the actual situation, the present embodiment does not do this any
It limits.As shown in figure 4, CPU1 can first read data needed for firmware upgrade in display 2, then by one frame frame of firmware data
Ground is written in the video output buffer in the first video processing module, then from one frame frame of the output port of the buffer
At this moment, in the data of output parallel output includes the video being made of horizontal blanking data, field blanking data and firmware data three
Data packet, also, the data in the video data packet are parallel data.Then by SDI stringization chip 3 by parallel firmware
Data are converted into serial digital signal, and according to sdi signal standard, are inserted into time synchronizing signal, into digital signal with complete
At the SDI stringization of data.Then the data after SDI stringization are sent to by CPU2 by the channel CVBS, then SDI unstrings chip
4 can be converted to serial digital signal parallel digital signal and splitting time synchronization signal, then abandon after SDI unstrings
Video data packet in horizontal blanking data and field blanking data, only extract firmware data therein, and by the firmware data
It is written in the plug-in NAND fLASh of CPU (one of fLASh memory), so that the firmware data replacement of write-in is original solid
