Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail by the following embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Fig. 1 schematically shows a block diagram of a photography control system 10 according to an embodiment of the present invention, the photography control system 10 being connected to a photography device for acquiring data of video, pictures, photography device parameters, etc. from the photography device and for controlling the photography device. As shown in fig. 1, the photographing control system 10 includes an image transmission and control device 11, a receiver 12, a remote control device 13, and a display device 14, and the parts of the photographing control system 10 are described below with reference to fig. 1.
Picture transmission and control device 11
The map transmission and control device 11 includes a processing module 111, a USB interface 112, an HDMI interface 113, and a WIFI module 114. The image rendering and control apparatus 11 is connected with the photographing apparatus via the USB interface 112 and the HDMI interface 113, and wirelessly communicates with the receiver 12 via the WIFI module 114.
When the USB interface 112 of the image rendering and control device 11 is connected to the USB interface of the camera device and the HDMI interface 113 of the image rendering and control device 11 is connected to the HDMI interface of the camera device, the image rendering and control device 11 detects that the device is inserted, and sends an initialization command to the camera device through the USB interface 112, the camera device opens the viewfinder function of the viewfinder according to the initialization command, and then the camera device transmits the video in the viewfinder to the HDMI interface 113 of the image rendering and control device 11 through the HDMI interface thereof. It will be appreciated that the advantages of using an HDMI connection are: the video transmission has no loss of analog-to-digital conversion, and can transmit high-quality video at high speed. The picture-taking and control device 11 acquires video captured in real time by the camera device via the HDMI interface 113, and the video acquired from the camera device is encoded by the processing module 111 into data suitable for wireless transmission, for example, according to the h.264 or h.265 protocol. The processing module 111 of the image transmission and control device 11 sends the encoded video to the receiver 12 via the WIFI module 114 for display by the display device 14 connected to the receiver 12. Since WIFI has volatility (e.g., instability of wireless signals, signal refraction, etc.), in order to obtain better playing effect at the display device 14, the graphics transmission and control device 11 automatically selects a currently appropriate channel for video transmission and adjusts the bitrate of video transmission before sending encoded video. Specifically, taking the 5.8G band including the available channels 149, 153, 157, 161, 165 as an example, the processing module 111 of the mapping and control device 11 is configured to find the optimal channel in the current network environment for video transmission according to the following manner: scanning channels under a 5.8G frequency band, selecting an idle channel as an optimal channel if the idle channel exists (namely the channel has no other interference), and selecting a channel corresponding to the minimum value in the maximum radiation intensity of WIFI as the optimal channel if the idle channel does not exist; if no optimal channel is found, the processing module 111 transmits the encoded video using the default channel 149. In addition, in addition to automatically selecting an appropriate channel, the graphics transmission and control apparatus 11 may automatically adjust the bitrate of video transmission according to the current network environment. Specifically, the processing module 111 of the graph transmission and control device 11 is configured to obtain frame loss and packet loss according to a defined real-time media feedback protocol, where RTT (round trip delay) exceeding a certain value is considered as humanly perceptible stuck, and if stuck times exceed a predetermined threshold within a defined video quality evaluation window, the code rate is decreased, and if stuck times are lower than the predetermined threshold, the code rate is increased. The image transmission and control device 11 adapts the video transmission to the current network environment by selecting the channel and adjusting the code rate, so that a better playing effect can be obtained at the display device 14.
The processing module 111 of the image transmission and control device 11 may also obtain the parameters of the photographing device (including but not limited to the state of the photographing device, such as on/off, power, etc.; photographing parameters, such as ISO parameters, white balance, etc.) via the USB interface 112 and transmit them to the receiver 12 via the WIFI module 114, and then the receiver 12 transmits them to the remote control device 13. Thereby, the user can monitor the current state of the photographing apparatus, photographing parameters, and the like through the remote control device 13 connected to the receiver 12.
After the user knows the parameters of the photographing apparatus through the remote control device 13 and watches the video captured by the photographing apparatus in real time through the display device 14, if it is desired to change the photographing effect, the user can input a control command for the photographing apparatus (i.e., a photographing apparatus control command) through the remote control device 13, and then the control command is received by the receiver 12 and transmitted to the photographing apparatus 11. After receiving the photographing device control command via the WIFI module 114, the image transmission and control device 11 converts the photographing device control command into a photographing device compatible control command by the processing module 111, and transmits the converted control command to the photographing device via the USB interface 112 (e.g., controls the photographing device based on the PTP protocol) to implement control of the photographing device (e.g., adjust photographing parameters, turn on/off a viewfinder, etc.). It should be understood that if the photographing apparatus control command received by the image transmission and control apparatus 11 is already a control command compatible with the photographing apparatus, the processing module 111 does not need to convert it.
Receiver 12
The receiver 12 includes a WIFI module 121, a processing module 122, a UART interface 123, and an HDMI interface 124. The receiver 12 wirelessly communicates with the map transmission and control device 11 via the WIFI module 121, is connected with the remote control device 13 via the UART interface 123, and is connected with the display device 14 via the HDMI interface 124.
The receiver 12 receives the encoded video from the graphics and control device 11 via the WIFI module 121, decodes it by the processing module 122 to obtain video in a format such as RGB or YUV, and sends the decoded video to the display device 14 for display via the HDMI interface 124. In addition, the processing module 122 of the receiver 12 also receives the camera device parameters from the map transmission and control device 11 via the WIFI module 121, and transmits the camera device parameters to the remote control device 13 via the UART interface 123 for display to the user.

The user may input the photographing apparatus control command through the user interaction module 133, and the user interaction module 133 of the remote control apparatus 13 transmits the photographing apparatus control command to the receiver 12 via the UART interface 131.
Display device 14
The display device 14 includes an HDMI interface 141 and a display module 142, and the display device 14 receives the decoded video from the receiver 12 via the HDMI interface 141 and displays the video through the display module 142.

According to the utility model discloses an embodiment, display module 142 can be 2K, 4K display, compares with the cell-phone, and this display can show the video that camera equipment caught in real time more clearly.

Picture transmission and control device 21
The map transmission and control device 21 includes a processing module 211, a USB interface 212, an HDMI interface 213, a WIFI module 214, and a UART interface 215. The image transmission and control device 21 is connected to the camera device via the USB interface 212 and the HDMI interface 213, wirelessly communicates with the receiver 22 and the mobile communication device 25 via the WIFI module 214, and is connected to the stabilizer 26 via the UART interface 215.
The picture-taking and control device 21 acquires video captured in real time by the photographing device via the HDMI interface 213, and encodes the video by the processing module 211. The processing module 211 of the image transmission and control device 21 transmits the encoded video to the receiver 22 and the mobile communication device 25 via the WIFI module 214 for display by the display device 24 and the mobile communication device 25 connected to the receiver 22. The processing module 211 of the map transmission and control device 21 automatically selects a current appropriate channel for video transmission and adjusts the bitrate of the video transmission, so that the video transmission adapts to the current network environment to achieve a better playing effect at the display device 24 and the mobile communication device 25.
