Security is one of the globally emerging electronic pillar industries. For example, the global security industry market size reached $138 billion in 2006 and is expected to exceed $201 billion by 2008. The vast majority of this consists of design, procurement, and operation costs for security electronics. The mainland of our country is the world's second-largest security industry base after the United States. However, we lead globally in the global shipment volume of major security electronic components. Our country's security electronic technology is rapidly rising and is expected to surpass the United States in the near future, becoming a new technological leader in the global security industry.
The suppliers of these products include both world-class enterprises rooted in the Chinese market and a large number of local small and medium-sized enterprises with high-tech capabilities. For instance, Beijing Panasonic Electric was the AV supplier for large venues such as the Bird's Nest, the International Broadcast Center, the Olympic Fencing Hall, the Laoshan Cycling Venue, and the Tianjin Olympic Center Stadium. The custom-made emergency command vehicle developed domestically for the Beijing Olympics will undertake on-site emergency command functions at the Olympic Games. Its video surveillance system requires reliability, stability, fast response, and the ability to detect emergencies in the first instance while preserving full video recordings after an incident. The vehicle is also equipped with a mobile GSM/GPS monitoring and alarm system for risk situation monitoring and command. Furthermore, the "Weiba Long" robot used in the Beijing Olympics mainly serves to defuse explosives, inspect and handle nuclear radioactive hazardous materials, and rescue hostages. In addition to remote wireless control, the robot's working arm can rotate continuously in both directions by 360 degrees, has a maximum extension distance of 3.5 meters, and can carry a load of 150 kilograms. The "Weiba Long" robot is equipped with four color all-directional monitoring cameras responsible for risk situation monitoring and emergency handling. Moreover, tens of thousands of cameras and related data collection, analysis, and processing systems have been installed in important facilities such as Beijing Olympic venues and subways.
From the perspective of patent deployment related to products and technologies, our country already possesses strong patent capabilities in the field of electronic security; the Beijing Olympics will further promote the global rise of patents in our country's electronic security industry. AV security technology. For example, document No. 200410047462.5 involves an information providing device, an information receiving device, and their storage media. It consists of a synchronization part that synchronizes AV data streams with metadata and a packaging part that packages AV data streams and metadata for each unit of metadata. By reconstituting metadata for each unit and packaging it together with the AV data stream, it can execute part of the metadata, allocate segments as part of the AV data stream, increase response speed, reduce necessary storage capacity, and minimize network congestion. Document No. 200410054600.2 involves an information recording medium and a device and method for recording or reproducing data. It is an information recording medium suitable for optical discs like DVD-RAM, provided for overall management of target data for different AV formats. The device is also used for recording data and playing media. The media stores management information, which includes program chain information for defining the playback order of targets and target information containing information related to the targets. The target information has general information about the target, attribute information, and mapping that relates the playback time points of the target to the address of the target component on the optical disc. PGC information contains cell information, which includes information about the type of target and identification information. The order of cell information in the PGC information corresponds to the order in which the target is played back.
For instance, document No. 02809862.5 involves a stream transformation method and device, related data recording method and device, and data recording medium. To encode the externally input AV signal into MPEG-TS that can be quickly transformed from MPEG-TS to MPEG-PS, define data units (multiplexing units), where data units include multiple data packets and have a data size corresponding to one data packet in MPEG-PS, and encode MPEG-TS for each defined data unit. Additionally, the time stamp information (ATS) added to the MPEG-TS data packet transformed into MPEG-TS and the time stamp information (SCR) added to the MPEG-PS data packet transformed are related to a predetermined formula. Document No. 200410042469.8 involves an AV synchronization system. When the flow used as the main reference stops, pre-register the priority of the main reference, consider the correction cycle of the system clock or the previous error, or send a stream containing information about the main reference, allowing other processes to be used as the main reference. Therefore, it provides a synchronization method that can maintain system clock correction. When the correction error is large, gradual correction or reference can give a normal feeling. Additionally, when the correction error is small, omitting correction or reference can reduce system overhead.

The antenna RF connects through the signal sending serial port and receiving serial port of the GSM module to the corresponding ports of the RS232 interface circuit, and the serial port P3.2 of the central processor CPU connects to the corresponding ports of the RS232 interface circuit, exchanging information with the mobile SMS center, completing real-time monitoring of the controlled vehicle. The data port of the central processor CPU connects through a latch to the program memory ROM and data memory RAM, completing program storage and data storage. This device receives satellite positioning data and vehicle status information, converts the data into protocol format, and transmits it back to the center in short message form through the GSM network.
Facial recognition technology. For example, document No. 200410058518.7 involves instant messaging status and identity management technology. First, a device such as a camera captures still images, video, and/or audio data. Then, relevant information is extracted and analyzed from the captured data.

Then, this information is interpreted for IM applications and provided to the application programming interface (API) of the IM application. The API can use the information for various purposes, including updating the user's status (e.g., available, busy, on the phone, away) and updating the user's identity. Document No. 200410047919.2 involves a method for normalizing the attributes of face image acquisition devices. Cameras, digital cameras, and digital cameras acquire N face images respectively and convert them into grayscale images. The N face images are trained, calculating the distribution function of pattern class centers, obtaining cumulative maps of pattern class centers for each face image acquisition device. Standard equipment and equipment to be converted are specified. Histogram statistics are performed on a face image acquired by the equipment to be converted, obtaining the cumulative map of the histogram of the image. The gray level order number of each pixel point in the face image acquired by the equipment to be converted is calculated, and its pixel gray value is reassigned, forming a transition image. The face image acquired by the equipment to be converted and the aforementioned transition image are fused at the pixel level, ultimately forming a normalized image of the acquisition equipment attributes. It can improve the recognition rate of face images acquired by different acquisition devices for face recognition.
Furthermore, document No. 200410101879.5 involves a face recognition method based on statistical texture analysis. It combines face recognition technology, pattern recognition, image processing technology, and statistical learning technology, proposing a completely new texture analysis method. First, the object to be analyzed is decomposed into multiple partially overlapping sub-objects. Then, multi-scale morphological wavelets are used to perform "structure element" analysis and extraction on the sub-objects to be analyzed at different scales. Statistical methods are used to classify patterns for each sub-object, generating a weak classifier for each sub-object. Finally, Bayesian networks are used to model the relationships between weak classifiers.
