Overcoming the limitations of the wired communication with the wireless video communication system and mobile communication system using the wireless module of the present invention (60) built-in Zigbee AP (70) wireless (video, audio, data) communication transmission such as emergency induction in the building By processing the signal by NTSC and PAL type FM / modulation / demodulation method, the image is processed to minimize the amount of data, thereby real-time signal processing at low cost and remote pulse detector (40) It remotely detects and monitors safety and transmits data through a wireless antenna relay (CDMA / WCDMA / ZigBee) transmission tower 100 to a receiver through communication with an AP through a location tracking Zigbee terminal 80 . It features.

In addition, the present invention is less costly because it is possible to process a plurality of transmitters in one receiver in a multi-channel method, the DB server of the present invention by processing a variety of signals for each user according to the user ID to each remote In the information sharing with the user, the user-specific data is blocked and posted to the administrator or the user's WEB or mobile-only program.

In addition, the signal of the wireless audio / video processing apparatus of the present invention is characterized in that the main circuit unit stores the signal as a signal and then stores the data as a low capacity signal. In addition, the transmission of the present invention is characterized by using a mobile communication company, the Internet network by transmitting from the wireless video / voice receiver to the DB server to the wired / wireless Internet. In addition, the application of the present invention is characterized in that it can participate in communication in real time using various mobile devices.

The present invention is a multi-channel operation method that can be used to manage the economical loss and various errors and maintenance problems caused by wired construction in the environment where the microphone and camera must be used by wire for communication with a remote site. By accommodating the transmitter, it is possible to drastically prevent the above-mentioned disadvantages, thereby reducing equipment costs.

In addition, it is not necessary to consider the wired language part in the user's environment, and additional cost is also inexpensive because only the channel is used to expand the equipment. In addition, it is possible to quickly establish a life by dispatching additional personnel to the exact location secured by reinforcing additional personnel when securing safety of fire suppression personnel and confirming survivors in case of fire or emergency relief.

Looking through Figures 1 to 3,

In order to transmit the video signal transmitted from the camera to the remote server through the wireless transceiver mounted on the goggle hair bend while both hands are inconvenient, the CCD camera 1 is installed. Compression module (2) for compressing the image taken therein and a hybrid switching module DSP (Digital Signal Processing) chip unit (4) equipped with a Binary WCDMA Signal module, a wireless transmission tool (3) to transmit it using a wireless communication network (3) ). Comprising a management server 10 for receiving and processing the compressed video, there is a receiver 11 and the storage unit 12 for receiving wireless communication transmission data, the decompression unit 12 'for decompressing Configured.

In connection with the decompression unit 13, it is possible to configure a monitor 20 that can immediately check the video. In addition, upload the decompressed video to the Internet so that it can be checked through the monitor 21 from a remote place over the Internet, and at the same time uploaded to WEB content to check on the WEB page or mobile communication such as a mobile phone or PDA equipped with a mobile explorer The terminal 30 to check the video.

In addition, the remote pulse transmission terminal 40 is delivered to the terminal via Bluetooth, the induction evacuation light 70 and the location tracking terminal 80 worn by the agent is installed.

According to FIG. 4 and FIG. 5,

First, if the camera's data is analog, the low-capacity byte is received as PCM (Pulse Code Modulation) data, the voice and video are separated, and the image data decompressed through the MPEG decoder is transmitted by the Binary WCDMA Signal module. The video can be separated through the video encoder, and in the case of audio, the video and audio processing module has a function of converting to other types of data or vice versa. In particular, a DSP chip is used and time switching is performed by a software control method. In this case, the switch relays one frame from one segment to another, and the present invention combines the advantages of cut-through switching and interim cut-through switching. to be. Instead of waiting for the entire frame to be received, the key to through switching technology is to analyze the destination address of the incoming frame to determine and send the corresponding transmission port.

In the present invention, as shown in FIG. 3 using packet scrambling, a GOP based error spreading (GES) scheme is used. For video packet scheduling, one video stream is divided into several GOP classes and placed in the frame memory of each class.

Figure 2 shows an example of a packet scheduling scheme for the 3GOP class. Three GOP class video packets are serviced by the Round Robin (RR) scheduler. The RR scheduler serves one video packet when visiting the class once.

The serviced video packet is scrambled with the video packets of other classes, and even if burst packet loss occurs in an error channel environment, the lost packet may be distributed through packet reordering at the receiving end. In more detail, in FIG. 2, video packets of 3, 8, and 5 suffer from continuous loss, but if the receiver undergoes reordering, the packets are distributed to packet loss existing in different GOP structures, thereby preventing the centralization of errors. have.

However, the video packet should be packetized with RTP packet prior to packet scheduling so that the receiver can reorder by Seqence Number (SN).

This reordering of the receiving end is a function of the video client supporting all UDP, and the complexity of the proposed algorithm does not increase significantly. It is a method to check the video of the field after authentication through the login ID and pass certified on the web or mobile by updating the video that is played through the packet scheduling method to the video server through the compilation for playback.
