[Previous technology] With the advancement of electronic technology, various security ministers' cameras are used in addition to recording programs in larger ... J surveillance systems. For example, if you want to install π at larger fixed points or at various fixed points in the community, you can patrol the factory building and shop at the same time. . In addition to providing a screen display, the Wenwang surveillance system sometimes provides a video recording function in order to ensure security. The Jaikang :: series of machines are connected to different displays and °. Storage: 'and different video recorders, but not easy to save = ί However, the video tape is not a different part of the storage medium ... when it is difficult to quickly move to the recording data, the knife cover is a sequential storage medium. Discs are a problem with electricity. Today, some people have switched to optical discs and hard media. Storage media is used to store the image data of such security surveillance systems. Second, ... ', the data involved in the video data is very large. If it is stored, it will not be compressed, and excessive computer storage media must be used. Therefore, most of the digital video recording systems currently used are usually compressed in mpeg format before the video data is stored. The problem is that, for the sake of the muscles, the master will charge the cost of the multi-handle Ap 'shirts, and some people will lead to a number of people according to the enemy ’s seven channels to capture unified computing funds # Share the valuable X π shell source.

The dynamic detection module continuously and separately measures these multimedia media; the data of the signal source is used to determine whether there has been a change that meets the predetermined conditions) to generate a detection result. For example, the motion detection module captures > frames per second, and compares the frames before and after the time point to determine whether there is an object moving in the area corresponding to the writing. The result of the dynamic test module is used as the basis for the sampling compression frequency of the compression recording module. For example, if the picture of a multimedia signal source does not have any object moving during the second period, reduce its compression frequency 6 1222835. In other words, the original compression recording of 20 day and night faces per second was reduced to compressive recording per second or even stopped compressing the recording frames under this detection result. After the compression recording module reduces the sampling compression frequency, the dynamic detection module increases the frequency of the pre-measurement. For example, if the original detection rate per second is changed to detection, it will detect 8 frames per second to quickly find any Problems, to avoid leakage of important information. &Amp; This sweat, with this dynamic adjustment sampling discrete time storage data standard pattern Z㈣ and also to adjust the relevant parameters, < the frequency of the relevant recompression action. Therefore, the present invention has at least the following frequency The system dynamically adjusts f, and before one hundred hundred, due to the compression sampling: the system computing resources will be greatly reduced ... In other words, in the application, when the force is different, recording can be performed more frequently without changing. This method is suitable for adopting a discrete daylight surface. In addition, the space can be used to record longer time data: that is, the 'utilization rate of the storage medium's processor' appropriately adjusts the compression; frequency: send: monitor the central office to use the idle off-peak time to re-exist the existing data 'It can even fully benefit the effectiveness and added value of the system.

An example of a multimedia signal source 12 is to obtain a signal through a camera and a recorder, such as a camera and a recorder. For example, in the application of the security source 12 a plus π / π η system, the multimedia source 12 is a camera with δ and at different positions. These multimedia signal sources are connected to the multimedia signal source, and the data from the 12 households is transmitted to the media. The interface 112 ′ tells the media that if the signal conversion of this photo-inducing load θ 转换 is switched. For example, if you connect the camera to an example + 勹 # ^. If you want to connect to the camera, the signal interface 1 12 1 includes one or more pieces of video data. 、 / Image capture card to convert the serial signal to a software interface, software, hardware or hardware mixed to the signal interface 1 2 =: =: body, firmware, hardware or dynamic Group 1.2 is continuous and the module is…. Health meets—predetermined conditions, " whether or not the media source No. 12 has issued a change in pre-conditions to generate-debt test results. For example, the dynamic 4 test mode Group 10h interface 1 2 I &food; private road day and day film, which regularly captures the daytime surface from = 12, and the difference between the previous daytime surface and the daytime surface is less than one if the changes occur If the value is “& U”, it is judged that the motion detection module 102 at the place where ^ w is not implemented is implementing a # ir τ θ plus the required pre-processing, such as detecting a :: ¥ can also increase the application *, can be ^^ ": whether the parking lot was invaded by thieves, m, on the photo brightness to adjust the meal, less than the ° row caused by the actual object movement. The mistake of updating the raw material is 1222835. For another example, the user can also set a mask to set the changes in the area they don't care about. For example, the parking lot only leaves the passageway without being masked. It can also reduce the calculation load of the motion detection module 丨 〇2. …. When the motion detection module 1 0 2 finds some of the multimedia signal sources ’resources: when there is an abnormal movement, or if there is no abnormal movement for a predetermined time, the movement: = Module 10 = Generation-Detection result. Connected to the dynamic debt measurement module ^ and the contraction recording module 1 04 are based on this detection result. The frequency is shrunk and used to compress and store the data from the signal interface 112; = source data. 7 Jesus II 1 The sampling compression frequency mentioned here refers to the number of times that the data of the multi-source 12 is acquired per unit time. For example, when there are no 12-series video signal sources in the multimedia media, when there is no object moving in the picture, 'yes; two = the signal source can be reduced to one second per second before compressing to produce data, Or simply stop capturing the picture data until the dynamic debt measurement mode 2 finds that there is an object moving again in the picture, and then the normal full sample compression frequency is restored. In the application of the security surveillance system, there are often many times when the daylight plane and the helmet captured by a certain camera of the multimedia signal source 12 move. … Will correspond to the sampling compression frequency of the camera ：:: Crisp stop ’Shikou. Although the camera is still sending data back to two. It is expected to waste the computing resources of the system in exactly the same day = nose. According to experience, data changes usually occur when the multimedia signal source 12 in different regions is not, ==, so the computing resources of the system can be moved to reduce waste. In this case, theoretically, the operation and distribution in the same system 9 can be controlled using the present invention. Simultaneous recording of the media signal source 12 of the evening. Then, the compressed recording module, such as discs, optical discs, magnetic tapes, etc., stores the data generated by the storage of the two or two, which is stored in the hard concept, for some time. In addition, as a result of referring to the processing plan of this issue, the data of Shimou Ti 5 彳 12 was uncompressed and put into the file of the storage medium: =: The data obtained by the compression operation is directly passed through the special building file format, using ... For example, this type of slotted grid = type is used to record multimedia data. When you play this file, you only need to maintain the violent face within 10 seconds before you play the next day and face specifications for writing. From the group ..., mother's heart picture data, broadcast—only Fan Fangwen. This method can greatly save the production of files η: ", the same storage media capacity, you can use this method to record the data content of fluorine for a longer period of time. The above-mentioned system can dynamically allocate resources to the needy multi-source sources of poor material recording, but it is also possible that all of the multimedia signal source 12's-materials are moving at the same time ', which may exceed the system load. One way to solve this problem is as follows. Since the compression recording module 104 will often cooperate with a central processing unit to perform the aforementioned compression recording operation, we can prepare a speed adjustment module U 0 to monitor the utilization rate of the central processing unit 108 (u ^ ge). If the usage rate of the CPU 108 is too high, it means that the $ shrink recording module 104 has used too much system resources. At this time, the compression recording module 104 dynamically adjusts according to the detection result of the speed adjustment module 11 〇 10 1222835 Its sampling compression frequency. If the utilization rate of ^, τ, and τ processors is more than 90%, some or all of the compressed recording and the frequency of removing and discarding the dimensional group 104 will be reduced by a certain percentage, such as compressing a frame per sample and so on. The mother ’s heart ’s day and time are changed to 8. In contrast, in another case, when the central processing unit 108 is idle, for example, at night, almost no one looks for an example in the camera area.

For some previously compressed data, the operation of re-compressing is performed in a higher or higher compression method, and the storage medium of N and N is compressed to increase. The recording time is long and the voice is also greatly different. Of course, the above-mentioned recording system 10 can also be connected to one or more display devices 14 for the use of the data of the multimedia signal sources 12 of this inverse.

Of course, the related multimedia will be integrated into the computer with the video signal source. Further, the content of the present invention will be explained. /, 'First application as an example, please refer to FIG. 2. The recording system 20 is connected to a plurality of displays 24. Among them, the recording system 2 has two cameras 22 and multiple faces, and dynamically displays these pictures.

For example, during a certain period of time, a specific scene ^ sighs to pause the recording, no object moves inside the cover / cover, and because of the extension of Bgangan, the camera of the famous camera 22 directly checks the sampling frequency. 0 frames per second. Then, when an object is detected in ~, 20 frames per second will be set. Then, according to the 4: I: sample editing rate is adjusted to compression recording each camera f compression frequency compression recording compression processing respectively central processing cry: (step 506). In addition, the # = rate is periodically checked (step 508), which can be obtained by the software by grabbing parameters from the driver of the CPU. Change in the rate (step 5), then adjust the sampling pressure two = 512; if one or two determine whether the CPU usage rate is lower than the predetermined value (step reduction information /, use the off-peak data to reduce the pressure at the previous low compression ratio) The operation of pressing and recompressing (step 514). The button that must be deducted, although the stand-alone concept here is certainly applicable to a system composed of multiple hosts. "Legend ... = then a larger one is dropped through the remote end. Recording system and system's user's work. Port 26 for parameter setting and daytime monitoring via network.
