Referring to fig. 3, fig. 3 illustrates an architectural diagram of an audiovisual entertainment device provided in accordance with some embodiments of the present invention.
As shown in fig. 3, in some embodiments of the present invention, the camera may be connected to the first LVDS serializer through the video conversion chip, and then connected to the processor through the first LVDS serializer and the first LVDS deserializer. The video conversion chip and the first LVDS serializer are both arranged inside an A column in front of the copilot, and the first LVDS deserializer can be arranged at a control system end of the vehicle, namely at the end where the processor is located.
In response to a live request from a user, the processor may first activate the camera to capture video images of the passenger in the co-driver seat. The video conversion chip is suitable for converting a video acquired by the camera into an Open low voltage differential (Open LDI) signal and transmitting the Open low voltage differential signal to the first LVDS serializer. The first LVDS serializer is suitable for first serializing the open low-voltage differential signal of the video to obtain serial data of the video, and then sending the serial data of the video to the first LVDS deserializer. The serial data may be an FPD-Link III signal.
In response to receiving the serial data of the video, the first LVDS deserializer is adapted to deserialize the serial data of the video to restore an open low voltage differential signal of the video. The first LVDS deserializer may then send the open low voltage differential signal of the restored video to the processor for further processing by the processor.
As shown in fig. 3, in some embodiments, the microphone may be connected to the first LVDS serializer through an audio to Digital conversion (ADC) module, and then connected to the processor through the first LVDS serializer and the first LVDS deserializer. The audio analog-to-digital conversion module is also arranged inside the A column in front of the copilot.
In response to a live request by a user, the processor may first activate the microphone to capture an audio signal of the passenger in the secondary seat. The audio analog-to-digital conversion module is suitable for converting an audio signal collected by the microphone into an integrated circuit built-in audio bus (I2S) signal and transmitting the I2S signal to the first LVDS serializer. The first LVDS serializer is adapted to serialize the I2S signal of the audio to obtain serial data of the audio, and then send the serial data of the audio to the first LVDS deserializer. The serial data may be an FPD-Link III signal.
In response to receiving the serial data of the audio, the first LVDS deserializer is adapted to deserialize the serial data of the audio to recover an I2S signal of the audio. The first LVDS deserializer may then send the restored audio I2S signal to the processor for further processing by the processor.

The second LVDS deserializer is arranged at the control system end of the vehicle, namely the end where the processor is arranged, and the second LVDS deserializer is arranged inside the A column in front of the copilot and is connected with the display screen nearby.
When a video file collected by the camera is played, the processor can send the open low-voltage differential video signal obtained by deserializing and restoring the first LVDS deserializer to the second LVDS serializer. In response to the open low voltage differential video signal provided by the processor, the second LVDS serializer is adapted to re-serialize the received video signal to re-obtain FPD-Link III serial data of the video, and then send the serial data of the video to the second LVDS deserializer. In response to receiving the FPD-Link III serial data of the video, the second LVDS deserializer is adapted to deserialize the received video serial data again to restore the open low voltage differential signal of the obtained video again. The display screen can play the video file collected by the camera to the passenger at the passenger seat based on the video open type low-voltage differential signal, so that the passenger at the passenger seat can check the live broadcast effect.
When the video file acquired from the cloud is played, the processor can send the open low-voltage differential video signal provided by the cloud server to the second LVDS serializer. In response to the open low voltage differential video signal provided by the processor, the second LVDS serializer is adapted to first serialize the received video signal to obtain FPD-Link III serial data of the video, and then send the serial data of the video to the second LVDS deserializer. In response to receiving the FPD-Link III serial data of the video, the second LVDS deserializer is adapted to deserialize the received video serial data again to restore an open low voltage differential signal of the obtained video. The display screen can play the video file that obtains from the high in the clouds to the passenger of copilot based on this video open low pressure difference signal to the passenger of copilot carries out the amusement.
