The 5G communication component 12 may adopt the 5GRG500Q module of Quectel, or other 5G modules. After receiving the online instruction sent by the decode module 20, the 5G communication component 12 may obtain the identification information ISMI of the SIM card through the USIM1_DATA (data pin) on the SIM card interface 13, and send the online request including the ISMI to the 5G communication antenna 11. The 5G communication antenna 11 sends the online request including ISMI to the base station. After the base station determines that the ISMI in the online request is valid, the 5G communication antenna 11 will receive a random number RAND sent by the base station, and then transmit the random number to the 5G communication component 12. The 5G communication component 12 may transmit the random number to the SIM card through the USIM1_DATA (data pin) on the SIM card interface 13. The SIM card obtains a response number SRES by performing an authentication algorithm on the random number, and transmits the SRES to the 5G communication component 12 through USIM1_DATA (data pin). The 5G communication component 12 then sends the SRES to the base station through the 5G communication antenna 11.

When the 5G communication component 12 detects that the SIM card type inserted by the user is a 3.3V power supply type SIM card through the USIM1_DET on the SIM card interface 13, the 5G communication component 12 outputs 3.3V for the SIM card through the USIM1_VDD on the SIM card interface 13. When the 5G communication component 12 detects that the SIM card type inserted by the user is a 1.8V power supply type SIM card through the USIM1_DET on the SIM card interface 13, the 5G communication component 12 outputs 1.8V for the SIM card through the USIM1_VDD on the SIM card interface 13.
The 5G communication antenna 11 includes multiple groups of antennas, which are divided according to mobile frequency bands. In order to increase the transmission rate, Multiple-Input Multiple-Output (MIMO) technology is adopted to correspond to the transmission and reception of mobile signals in three groups of frequency bands.

The core processing unit 25 also controls the decode unit 22 to perform image enhancement processing on the video data, so that the video data after the image enhancement processing is sent to the OSD video synthesis unit 23. When the audio processing unit 24 receives the audio data, the core processing unit 25 controls the audio processing unit 24 to process the audio data (such as sound quality improvement, noise reduction, etc.), so that the audio and video module plays the processed audio data. For the decoded video data, the decode unit 22 also performs image enhancement processing on the video data, and sends the image enhancement processing video data to the OSD video synthesis unit 23. After the OSD video synthesis unit 23 receives the video data processed by the image enhancement process, it superimposes an OSD layer on the video data processed by the image enhancement process to obtain the video data of the superimposed OSD layer, and send the video data of the superimposed OSD layer to the audio and video playback module 30.
It should be noted that each unit in the decode module 20 transmits data and signals through a V-BY-ONE interface. In the current protocol standard, the signal that can be transmitted by a group of 8 LANE V-BY-ONE interface signals is 4K/60 HZ signals. To transmit 8K/60 HZ signals, 4 groups of 8 LANE V-BY-ONE interfaces are required.
A pin connection is provided between the core processing unit 25 and the 5G communication component 12 as the output end of the 5G communication module 10. The core processing unit 25 sends an online instruction to the 5G communication component 12 through its pins to control the 5G communication component 12 to enter the online mode or send an offline instruction to control the 5G communication component 12 to enter the offline mode. The core processing unit 25 also send a status acquisition request to the 5G communication component 12 through the pins, such that the 5G communication component 12 feeds back to the core processing unit 25 through pins whether the current working mode of the 5G communication component 12 is the online mode or the offline mode. For example, DISABLE pin is a pin for the decode module 20 to control the working status of the 5G component. When the core processing unit 25 sets the DISABLE pin to a low level, the 5G component enters the offline mode, and when the DISABLE pin is set to a high level, the 5G component enters the online mode.

After the OSD video synthesis unit 23 determines that a frame frequency of the video data sent by the decode unit 22 is greater than a display frequency of the display unit 31, the FRC frequency multiplication module 40 performs frequency multiplication processing on the video data of the superimposed OSD layer received from the OSD video synthesis unit 23. Therefore, the frequency of the video data is increased to be the same as the frequency of the display unit 31, and then the frequency-multiplied video data is sent to the display unit 31 so that the display unit 31 plays the frequency-multiplied video data. For example, when the OSD video synthesis unit 23 receives that the video data sent by the decode unit 22 is 8K/60 HZ, and the display unit 31 is 120 HZ, the FRC frequency multiplication module 40 performs frequency multiplication processing on the video data, converts the 8K/60 HZ video data into 8K/120 HZ video data, and then sends the 8K/120 HZ video data to the display unit 31. By adding the FRC frequency multiplication module 40 between the OSD video synthesis unit 23 and the display unit 31, the FRC frequency multiplication module 40 is configured to increase the frequency of the video data lower than the frequency of the display unit 31 to be consistent with the frequency of the display unit 31, thus, the picture in the process of playing the video data on the display unit 31 is smoother.
It should be noted that when the OSD video synthesis unit 23 determines that the frame frequency of the video data sent by the decode unit 22 is not greater than the display frequency of the display unit 31, the OSD video synthesis unit 23 superimposes the OSD layer on the video data, and then directly sends the video data of the superimposed OSD layer to the display unit 31, so that the display unit 31 plays the video data of the superimposed OSD layer.
