Method Embodiment In the Bluetooth module of the monitoring front end (also referred to as the monitoring end) and the monitoring display end (also referred to as the display end) of the embodiment, it is required to support the VDP, Bluetooth audio/video remote control application framework (Audio/Video Control Transport). Protocol, abbreviated as AVRCP) and A2DP. Among them, VDP, A2DP Bluetooth protocol is responsible for transmitting and processing video data and audio data respectively, and AVRCP is responsible for transmitting and processing remote command data (also called control message). The VDP and A2DP Bluetooth protocols can wirelessly transmit the video and audio information acquired by the monitoring front end to the monitoring display terminal to realize wireless transmission of video and audio information. The remote control command of the monitoring display terminal can be wirelessly transmitted to the monitoring front end through the AVRCP Bluetooth protocol. The remote control command, the monitoring display can remotely monitor the action, for example, you can stop monitoring, start monitoring, select sound-only monitoring or select only video image monitoring. The present embodiment will be described in detail below. According to an embodiment of the present invention, a Bluetooth-based monitoring method is provided. To better describe the embodiment, the processing of the monitoring front end and the monitoring display end will be separately described. Firstly, the processing of the display end is introduced. The display end receives the video and audio data transmitted from the monitoring front end, and after decoding, forms a multimedia file that can be played, and is played by the audio video playing function device (for example, the media player in the mobile phone) on the monitoring display end. The corresponding video and sound, complete the monitoring process. 1 is a flowchart of a Bluetooth-based monitoring method according to an embodiment of the present invention. As shown in FIG. 1, the processing of the display terminal includes the following steps: Step S102 to Step 4: S Step 102: Display terminal through Bluetooth The video distribution framework receives the video data from the monitoring terminal, and/or receives the audio data from the monitoring terminal through the Bluetooth advanced audio distribution protocol; step 4 gathers S 104, and the display side plays the video data and/or the audio data. Preferably, the display terminal can also send a control message through the Bluetooth audio/video remote control application 4 truss protocol, wherein the control message is used to instruct the monitoring terminal to perform a predetermined operation. That is, for the monitoring front end and the monitoring display end, the remote control extended command transmission can be realized by supporting the AVRCP protocol, and the remote control operation of the imaging and recording parts can be realized by the extended command, for example, turning off/on the power, suspending/stopping/ Start monitoring, mute monitoring, sound monitoring, etc. to meet different user needs. Preferably, the display can save video data and/or audio data. That is, the audio and video data can be simultaneously stored on a storage medium (for example, a T card in the mobile phone) for backup for viewing by the user. The following describes the processing of the monitoring terminal. The processing of the monitoring terminal (ie, the monitoring front end) includes: firstly, acquiring audio and/or video data of the monitoring object, and encoding and processing the obtained audio and/or video data, and transmitting the data to the Bluetooth function module by the Bluetooth module. The real-time audio and video wireless transmission functions such as A2DP and VDP are transmitted to the monitoring display terminal of the back end for processing. Preferably, an additional encryption algorithm may be added in the encoding process to avoid leakage or interception of the transmitted data. Among them, the audio and video data of the monitoring object can be obtained through the recording device and the video recording device. According to the requirements of monitoring the audio clarity and the video image, the recording device and the video recording device can be selected to meet the actual needs. Specifically, the processing of the monitoring terminal includes the following steps S202 to S206: Step S202, the monitoring terminal acquires video data and/or audio data. Step S204, the monitoring end encodes the video data and/or the audio data. Step S206, the monitoring end sends the encoded video data and/or audio data to the display end. It should be noted that before the monitoring is performed, a Bluetooth wireless link (including establishing all links of A2DP, VDP and AVRCP) is established between the monitoring front end (ie, the monitoring end) and the Bluetooth module of the monitoring display end (ie, the display end). . The Bluetooth wireless link can be manually established by the user, or can be set by the monitoring front end and the monitoring display end, and the two parties automatically initiate the establishment of a Bluetooth wireless link after the power is turned on. The implementation process of the embodiment of the present invention will be described in detail below with reference to examples. 2 is a schematic diagram of a Bluetooth-based monitoring terminal and a display terminal according to an embodiment of the present invention.

The mother can also go from the kitchen to the study or bedroom. The Bluetooth link can be kept on the move, thus realizing the dynamic conversion of a monitoring system (device) in different scenarios, which is very simple and low cost. The monitoring method specifically includes the following steps: Step S110, performing a Bluetooth wireless link on the monitoring front end and the monitoring display end (the Bluetooth link includes simultaneous links of A2DP, VDP, and AVRCP), and the Bluetooth wireless link can be set as a boot automatic link or a user manual link. . Step S120, placing the 4 head and the microphone of the monitoring front end on the monitoring target or area, The acquisition of video/audio data of the monitoring target is separately implemented.

Step S130: The video/audio data of the monitoring target is encoded and transmitted by the Bluetooth wireless transmission function to the monitoring display end, and the Bluetooth A2DP and VDP protocols that keep the link are respectively responsible for transmitting the audio data and the video data. Step S140, the monitoring display end receives the video/audio data, and after decoding, synthesizes the audio/video data into a video file containing video/audio information that can be played by the corresponding information processing, and plays the monitored target through the media player.
