Implementation] = (4) to solve the purpose, characteristics and effects of this creation, by the following: "list" and with the attached drawings, a detailed description of the creation, as follows: Lose Z-based (5) For a circuit block diagram of a preferred embodiment, please refer to Fig. 5, 'The signal capture compression and conversion processing system of the present invention* includes ♦ a planar right angle display controller unit 5 (for example: -W, but not limited to this) It can receive a plurality of types of video signal sources 6 (for example: an image edge array ship number VGA", a digital video interface signal, DVI" or L video VIDEO 'this is a popular name 'but not limited to this) And drive the drive signal 7' where the flat right angle display controller is two. The S-video signal multiplexer 16 selects a compression and conversion processor 8 (for example, FpGA/DSp/Asic, etc.) from the analog video source 6 to select an analog video signal to be processed. And the signal extraction and conversion processor 1 includes: - a virtual display interface unit 9 that receives the display interface driving signal 7 and converts it into - continuous video昼面信号1G, a continuous video signal unit 11 (for example: an MPEG-4 shirt like compression unit or -jpeg·2 unit image compression unit, but not limited to this) 'it receives the continuous video frame The signal is compressed into a continuous video buffer _: #料12, the data temporary storage area buffer unit 23, which receives the continuous video compressed data 12, the output/input unit 9 M320813 (7) t Ethernet Or -usb interface, but * is limited to this), after the output of the buffer = material temporary storage area buffer unit 23, the continuous video surface (four) data 12 is output, and the second central control unit "control interface unit 14" and the virtual Display interface unit 9, 2^= 昼: signal The shrinking unit 11, the data temporary storage area buffering unit 人^人早7〇13 and the parameter feedback collecting unit-central processing unit 15, the 央 央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央 中央Or mouse, etc.), the parameter two verticals - (such as: the display system is crying, the c is on the top of the block, and the plane is displayed at right angles. 26 2: Adjust the feedback control parameters and control the plane right angle display control: 2: the monitored end # vertical device 27 (such as: keyboard or mouse, etc.), the processor controls the interface unit 14 to control the signal capture And the conversion processor 8, wherein the parameter feedback collection unit 24, the basin, the central processor control interface 14 from the output A unit 13 touches the breeding stream 25' by the parameter feedback collection unit % Receiving the output to the central processing unit 15 to make a decision decision, the central processing unit is connected to the monitored end effector 27 (eg, a keyboard or a mouse, etc.), as designed by the visual system The controlled system can be further passed through the ATV end effector 27 (eg keyboard or mouse) The operation of the monitored system is as follows: , for a more detailed description of the blocks shown in the figure: L plane right angle display controller unit 5: 帛 6 picture is the internal circuit of the plane right angle display controller unit 5 Block diagram.

The drive signal of the final output display interface is also quite complete. The planar right-angle display controller unit 5 can programmatically change the attribute of the source of the continuous video signal, and re-adjust the effective resolution range of the continuous video signal output without affecting the sharpness of the picture. Referring to the parameters of the remote monitor feedback, the range control definition of the effective resolution of the display interface driving signal 7 is adjusted and changed, and as the compression source of the continuous video surface, the compression is performed to obtain the optimal compression surface. Data capacity. 2. The video signal multiplexer 16 is present in the plane right angle display controller unit 5. When the plurality of types enters simultaneously with the video signal source, the software setting can be used to allow only one of the signals to enter the plane right angle display controller unit 5. It can be directly learned by the software (the internal hardware circuit can directly measure the complete and effective analog video signal) the analog video signal source that you want to process. 3. The signal acquisition compression and conversion processor 8 is characterized in that the conversion display interface driving signal 7 becomes a continuous video signal 10 as a source of image signal compression. And using a continuous video signal compression unit 11 to perform compression to generate a continuous video compressed data 12, which is received by a data temporary storage area buffer unit 23, and finally transmitted through the output/input unit 13 and the data temporary storage area. The buffer unit 23 is connected to each other and outputs the compressed video 12 for the continuous video. 4. Virtual display interface unit 9: Figure 7 is a detailed system block diagram of 11 M320813 of virtual display interface 9. The display interface driving signal 7 outputted by the controller unit 5 can be converted into a signal that can be processed by the continuous video signal compression unit 11 through the virtual display interface 9, because the plane is displayed at right angles. The control unit 5 can output several display interface driving signals (for example, the display interface driving signal of the TTL/LVDS/RSDS specification), and the compression result of the different effective resolution range will affect the different surface data compression capacity. When the planar right angle display controller unit 5 outputs the effective resolution range to the virtual display interface unit of 9%, it must be fully supported and can capture the complete data, and finally convert the compatible with the continuous video signal compression unit n. A signal that can be processed. 5. Continuous video signal compression unit 11: Figure 8 is an internal circuit block diagram of the continuous video picture signal unit (for example: JPEG_2_operation block diagram, but not limited to this). The main reason is to compress the complete continuous video signal 1G through programmable programming. _ data size _ to the transmission speed and decompression performance, so if you simply convert the analog video signal source into a continuous video signal 1 〇 compression (if the plane right angle display controller unit 5 can not adjust the effective resolution of the sound range definition ) 'There may be a large area of effective surface resolution, so that the compression tb rate will be worse (sometimes even unable to shrink), and affect the large area of the effective resolution range of the speed of transmission and The performance of the solution (or can not be transmitted), _ affects the quality of the M320813 overall instant face operation, another way to omit the block (ignoring the continuous video face signal compression unit 3 directly output image (four) output) function, may Because there is no % state image, the poor material capacity is too large, so that the remote monitoring H goes to the "instant" monitoring operation. Therefore, the better one is the signal = the compression display processor 8 is matched with the plane right angle display controller: 兀5 adjusts the optimized resolution range of the image to face early (large area reduction © product, if * influences the surface The original of the sharpness: b) The image is compressed by the image, and the optimal data capacity of the compressed data can be obtained (the size of the image can also be reduced by a small amount).

The following is a comparison. Take MJPEG·· adopt the gradual transmission method, first input the low resolution slot, and then replenish the detailed data. The quality of the kneading is improved to the best. The compression can obtain very sharp images, and the enamel and resolution can be customized at any number of frames per second, and because each scene is independent of each other. The overall impact of data corruption is small, the viewing end does not need to be the overall association is decompressed, only f streaming video playback, does not consume too much hardware resources, can achieve the effect of low image delay. 'There will be no copyright issues. Compared with other _ formats, the overall efficiency of the county is low and the storage space is the main disadvantage. The algorithm is based on the content of each image, rather than the neighbors. The difference between the 13 M320813 images is compressed. This results in a large amount of redundant image loss being stored repeatedly. The bandwidth is not occupied by the action, and the storage space is large. MPECM: The video will be analyzed. Foreground, background, as long as the trajectory of the dynamic image is recorded, the program performance is increased, and the compression ratio is hundreds of times higher. The application target is for low-frequency wide transmission, high-shell compression, interactive operation, and natural objects and artifacts. The expression of fusion. However, due to the complexity of the algorithm, there is some degree of interference between image interference and distortion of the face. Moreover, because of the compression technique between the images, only the segment image is supported = 'Know' That is, the image compression data may be inconsistent to cause the overall material to be known. When the object is in motion, the technology does not react immediately, so the delay is serious. 6· f temporary storage area buffer unit 231 When the signal is com, the single 70 11 and the output/human unit's compression operation and the second round of the transmission are not synchronized, the current compressed data can be temporarily used to wait for output. The most obvious operation is: When the continuous kneading signal compression single * η operation speed is faster than the output / = 13 transmission speed, the current compression data must be first to wait for the input A, buffer function The complete video capture will be transmitted to the remote monitor. The function of the buffer unit 23 is: 7. Under the round material, the video can still be played. 7. The device type of the unit must be determined according to the receiving interface of the 320813 host unit 20, which can be USB, IEEE1394, Ethernet or PCI, but It must be noted that the output/input unit 13 must have a two-way transmission capability to achieve the "remote monitoring" function. 8. Central Processing Unit 14: The most important function is in the central processor unit 15 and the signal 撷An unobstructed and compatible access interface can be established between the compression and conversion processor 8 because of the city

Fully compatible, the central processor unit 15 can be designed to be more flexible in hardware planning. Of course, if there is an access interface that is completely compatible with the central processor unit 15 of the signal acquisition compression and conversion processor 8, the layer interface unit can be omitted. 9. Parameter feedback collection unit 24: The remote monitor 21 passes through the feedback path and finally reaches the output/input unit 13 and then converts into the parameter feedback data stream 25' and is received by the parameter feedback collection unit, filtered, and processed.
