Description of the Invention: [Technical Field] The present invention relates to a data transmission method and apparatus, a data receiving method and apparatus, and a computer program product thereof. More specifically, the present invention relates to a data transmission method and apparatus for transmitting data by video streaming technology, a data receiving method and apparatus, and a computer program product thereof. [Prior Art] Φ In recent years, due to the popularity of the Internet, many hardware and software devices transmit data through the network, which greatly increases the amount of data transmitted in the network. For example, in order to monitor the operation status of each machine and/or plant in the plant, inductive equipment can be installed around each machine or/and the plant. The monitoring center of the factory can collect information related to each machine or/and plant from the sensor. , such as ambient temperature, ambient pressure, machine speed, etc., to speculate the actual situation. In another example, each branch of the power company must pass back the electricity usage of local users. Since the plant/power company has multiple branches, it needs to transmit and receive a large amount of data. The data collection of the above examples may have hundreds, pen, or even tens of thousands of data inflows at each point in time, resulting in a significant increase in the bandwidth usage and a reduction in the transmission rate of the data. The conventional technique is to transmit the value of the physical quantity detected by each data source (for example, the sensor set by the factory) directly to the monitoring center at a fixed time without special treatment. Therefore, in the case of huge influx of data, it will cause network congestion and/or insufficient bandwidth. In addition to this, conventional techniques only perform point-to-point data transmission. In the case of the aforementioned factory, only the monitoring center can receive and view the data. However, in some cases, 201010436 not only monitors the need to know the actual situation, but also the operation of the plant in other departments. The conventional technology does not provide a solution in this respect. Therefore, the mechanism for transmitting data for network data is In order to reduce the trend of the network = how to design - the problem that the technicians in the fast domain need to solve. The problem of the transfer and the bandwidth is not the same as the collar [invention] The spoon = invention - the purpose is to provide a kind of data transmission method. This data transmission method 2 = step 1 (: received from multiple sources) In the first-data; (9), the first-image frame contains a plurality of __ gold elements\the first image frame (fr_), wherein the first-pixels are--; (4) from the first-data corresponding to the material; (4) The second data frame is respectively received by the second data frame, and the second frame includes a plurality of second pixels, each of the frames, wherein the second pixel is one of the second pixels. One-bean material corresponds to the equalizers respectively.

Another object of the present invention is to provide a computer program product comprising a plurality of instructions. The computer program product can load the program via a computer and complete the above data transmission method. Another object of the present invention is to provide a data receiving method, the data receiving method comprising the steps of: (a) receiving a movie transmitted by using the data transmission method described above; and (b) decoding the film to obtain a first image frame. And a second image frame, wherein the Φ first image frame includes a plurality of first pixels, the second image frame includes a plurality of second pixels; (c) performing an operation on each of the first pixels Obtaining a first data, respectively, causing each of the first data to correspond to one of a plurality of data sources; and (d) performing the operation on each of the second pixels to obtain a second data, Each of the second materials corresponds to one of the sources of the data. Still another object of the present invention is to provide a data receiving apparatus including a receiver, a decoder and a converter. The receiver is configured to receive a video transmitted by the data transmission device. The decoder is configured to decode the video to obtain a first image frame and a second image frame. The first image frame and the second image frame respectively include a plurality of first pixels and a plurality of second pixels. The converter is configured to perform operations on each of the first pixels to obtain a first data, and perform operations on each of the second pixels to obtain a second data, so that the first data respectively correspond to To one of a plurality of sources, each of which corresponds to one of the sources. Still another object of the present invention is to provide a computer program product, the computer program 201010436 product comprising a plurality of instructions, the computer program product can be loaded into the program via a computer and the above data receiving method is completed. In summary, the transmitting end of the present invention corresponds each of the data sources to a pixel at a certain position in the image frame. Then, the data received at different time points will be filled in the corresponding positions of the pixels in the image frame according to their data sources. Later, through the coding technology, the amount of data to be transmitted can be greatly reduced. When the source of the data is approximated at a near-term point in time, the amount of data that can be reduced is greater. In combination with a standard video streaming technology, it can be applied to existing platforms without special format conversion. In addition, the video streaming mode can also achieve a multi-point to multi-point data exchange architecture, that is, the user can simultaneously monitor the data of different transmitting ends, and each transmitting end can also view the data of the user end. The receiving end of the present invention adopts a technology corresponding to the transmitting end, so that the data transmitted from all data sources can be obtained while receiving a small amount of data. The above described objects, technical features, and advantages of the present invention will become more apparent from the following description.

Then, the converter 113 stores the first data 121&'122&,..., 129a and the second data 121b, 122b, ..., 129b stored in the memory 112 into a first image frame and a second image of a movie. frame. The details will be described in detail below. μ refers to the 1C and 1D drawings, which are schematic diagrams of the first image frame n3a and the second image frame (10), respectively. The first image frame and the second image frame are the same as the image frame. The first image frame 113a includes a first pixel lma, a lion, a coffee, a 1136a, a 1137a, a 1138a, a U3Qfl, and a U 39a, and a second image frame 113b i3kM1131b, 1132b, 1133b, U34b, ii35bii3 U38b, U39b. The converter H3 will first determine the correspondence between the first data 1213, 122 &, . . . , and the first pixels ima, U32a, 1133a, U34a, U35a, ima, n37a, m (1), and the second The correspondence between the data im, 12沘, ..., (4) and the second pixels ll3lb, 1132b, 1133b, 1134b, U35b, u36b, ii37b ii38b, 1139b. Specifically, the converter 113 corresponds the first data 12u, ma..., (4) 201010436 to one of the first pixels 1131a, 1132a, ..., 1139a, respectively. For example, the converter 113 may correspond the first material 121a to the first element 1131a, the first data 122a to the first element 1132a'... and the first material 129a to the first picture 1139a. Similarly, the converter 113 maps the second data 121b, 122b.....129b to one of the second elements 1131b, 1132b.....1139b, respectively. For example, the converter 113 may correspond the second material 121b to the second pixel 1131b, the second data 122b to the second pixel 1132b, ..., and the second material 129b to the second pixel 1139b. The above is a preferred method, that is, the converter 113 corresponds the data from the same data source to the same relative position of the image frame, for example, the first data 121a and the second data 121b of the data source 101 respectively. The upper left corner pixels of the first image frame 113a and the second image frame 113b (that is, the first pixel 1131a and the second pixel 1131b). The advantage of this preferred correspondence is that the data of the same data source at the adjacent time points have similarities and correlations, and corresponding to the pixels of the same relative position of the image frame, so that the subsequent processing can be applied to the similarity between the data. Correlation, to achieve better results. Corresponding to the first pixels 121a, 122a, ..., 129a to the first pixels 113 la, 1132a, ..., 1139a and the second data 121b, 122b..... 129b to the second pixels 1131b, 1132b After ..... 1139b, it is further explained how the converter 113 specifically forms the first image frame 113a with the first data 121a, 122a.....129a, and how specifically the second data 121b, 122b.. ...129b forms a second image frame 113b. The first embodiment provides the following manners for specifically forming the first image frame 113a and the second image frame 113b. 201010436 In the first method of forming the first image frame 113a and the second image frame 113b, each of the first pixels 1131a, 1132a, .., 1139a and the second pixels 1131b, 1132b, ..., 1139b is 24 Bit. The converter in fills the 16 bits of each of the first data 121a, 122a, ..., 129a, 121b, 122b, ..., 129b into the 24 bits of the corresponding first pixels 1131a, 1132a, ..., 1139a 16 yuan in the yuan. Further, the converter 113 fills in the relevant data with one of the first data 121a, 122a, ..., 129a to fill the remaining 8 bits of the corresponding first pixels 1131a, U32a, and U39a. The same 'converter 113' fills the 16 bits of each of the second data 121b, 122b, ..., 129b into the 16 bits of the corresponding 24-bit 24-character i131b, U32b, ..., 1139b. In addition, the converter 113 also checks the relevant data of one of the second data 121b, 122b, ..., 129b into the remaining 8 bits of the corresponding second pixels 1131b, 1132b, ..., 1139b. Please refer to the IE, IF diagrams for the two examples of the first formation method. Specifically, Fig. 1E depicts the 24-bit of the first pixel ii31a, and the converter 113 fills the first data ma from the data source 101 with the lowest bit of the first pixel H3la φ. And so on to the other first data 122a, ..., 129a and other first pixels 1132a, ..., 1139a between the filling position, and the second data 121b, 122b, ..., 129b and the second element 1131b, Fill in the bit position between 1132b, ..., 1139b. The IF picture depicts the first pixel in another example! Uia's 24-bit, converter 113 fills the first data 12la from the source ιοί into the 16-bit middle of the first pixel 1131a. The filling position between the other first data 122a, 129a and the other first pixels 1132a, ..., 1139a, and the second data 121b, 122b, ..., 129b and the second pixels i131b, U32b, n39b 13 201010436 fill in the position of the bit, and so on. In the second method of forming the first image frame 113a and the second image frame 113b, each of the first pixels 1131a, 1132a, ..., 1139a and the second pixels 1131b, 1132b, .., and 113% includes one Red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Each red sub-pixel R, each green sub-pixel G, and each blue sub-pixel are 8-bit. The converter 113 fills the first data 121a, 122a, ..., 129a with the corresponding red sub-pixels R, green sub-pixels Q and blue of the corresponding first pixels 1131a, 1132a, ..., u39a, respectively. Two of the dice pixels B, for example, red scorpion R and green sub-pixel G. The converter 113 fills in the relevant data with one of the first data 121a 122a, ..., 129a, and fills in the red sub-pixel R, the green sub-pixel G and the blue of the corresponding first pixels 1131a, 1132a, ..., U39a. The other one of the dice pixels B, such as the blue sub-pixel b. Similarly, the converter 113 fills the second data 121b, 122b, ..., 129b into the corresponding red sub-pixels R, green sub-pixels G of the corresponding second pixels 1131b, 1132b, ..., 1139b, and Two of the blue sub-pixels B, for example, the red sub-pixel R and the green sub-plasma converter 113, and the corresponding information of each of the second data i2lb, 122b, ..., 129b is filled in corresponding data. The second picture element 丨丨3 lt>, 1132b, ..., 1139b of the red sub-pixel R, the green sub-pixel G and the blue sub-picture B are the other ones such as the blue sub-pixel B. FIG. 1G is a specific example, and the ig diagram depicts the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B of the first pixel 1131a, and the converter 113 will receive the first data from the source 101.丨2ia fills in the red sub-pixel R and the green sub-alloy G in the first pixel 1131a. Assume that the value of the first data 121a is 20000, 20000 bis. The 201010436 carry is represented as 0100111000100000. Therefore, the red sub-pixel R and the green sub-alloy G are filled in with 20000, that is, the first octet 01001110 (the decimal value is 78) of 0100111000100000 is filled in the red sub-pixel R, and the bundle eight bits of the 〇10011100010000〇 Yuan00100000 (the decimal value is 32) is filled in the green sub-pixel G. The rest is analogous. Please refer to page ΙΑ, 1B again. After the converter 113, the first data 12la, 122a, ..., 129a and the second data 121b, 122b, ..., 129b have respectively formed the first image frame 113a and the second image frame ii3b of the φ movie. Next, the encoder 114 The movie including the first image frame 113a and the second image frame n3b is encoded as one of the video bitstreams. Thereafter, the encryptor 115 encrypts the movie, i.e., encrypts the video stream file. Finally, the transmitter 116 transmits the video stream file 171 (with the movie contained therein) to the word processor 13 in a video stream. It should be noted that in other embodiments, the data transfer device u may not include the encryptor 115' and the transmitter 116 may transmit the unencrypted video stream to the server 13. In some implementations, the transmitter 116 can directly stream the movie string φ to the client. As mentioned above, the data values detected by the same data source at similar time points are similar (for example, similar time points, ambient temperature, pressure, etc. are almost constant), and corresponding to the same relative position of different image frames. . Based on this approximation relationship and correspondence, the encoder 114 can compress the movie into a video stream file by using a video compression method to reduce the amount of data that the tributary transfer device u needs to transmit. Further, the encoding and compression performed by the encoder ii4 can conform to the standard of the moving picture experts group (MPEG) and the video stream file 117 conforms to the format defined by the motion picture 15 201010436 expert panel. So far, the first part of the operation of the data transmission receiving system 1 has been described. Next, the operation of the second aspect of the data transmission and reception system 1 will be explained, that is, from the server 13 to the data receiving devices 15a, 15b, 15c to the client terminals 17a, 17b, 17c. Please refer to Fig. 1H, which is a data receiving device 15a, 15b, 15c. The data receiving devices 15a, 15b, 15c each include a receiver 151, a decryptor 152, a decoder 153, and a converter 154. First, the receiver 151 receives from the server 13 the video stream file 171 transmitted by the data transmission device 11, and the video stream file 171 contains a movie (i.e., a movie previously formed by the data transmission terminal 11). Since the encryptor 115 of the data transfer device 11 previously encrypts the movie, the decryptor 152 of the data receiving device 15a, 15b, 15c decrypts the video stream file 171. If the encryptor 115 is not provided in the data transfer device 11, the data receiving devices 15a, 15b, and 15c do not need to provide the decryptor 152. The decoder 153 decodes the decrypted movie_stream file 171 (including the movie) to obtain the first picture frame 113a of the 1Cth picture and the second picture frame 113b of the 1D picture. The decoder 153 performs decoding in a manner corresponding to the encoder 114. For example, if the encoder 114 is encoded in a manner consistent with the standards of the Motion Picture Experts Group, the decoder 153 also decodes in a manner consistent with the standards of the Motion Picture Experts Group. As described above, the first image frame 113a includes first pixels 1131a, 1132a, ..., 1139a, and the second image frame 113b includes second pixels 1131b, 1132b, ..., 1139b. The converter 154 is configured to perform an operation on each of the first pixels 1131a, 1132a, ..., 1139a to obtain first data 121a, 122a, ..., 129a, respectively, and for each of the second pixels 1131b, 1132b. ..... 1139b performs an operation to obtain the second 201010436 data 121b, 122b, ..., 129b, respectively. The converter 154 corresponds to the converter 113 of the data transmission device u, and also sets the data calculated by the pixels of the same relative position of the image frame to correspond to the same data source. For example, the first data 12u obtained by computing the upper left pixel of the first image frame 113a (ie, the first pixel 1131a) and the upper left pixel of the second image frame n3b (ie, the second pixel 1131b) The second data 121b obtained by the operation corresponds to the source ιοί. By analogy, the first data 122a and the second data 1221? φ should correspond to the data source 102, ..., the first data 129a and the second data 129b correspond to the data source 109. Next, how the converter 154 calculates the first data 12ia, 122a, .., 129a and the second data 121b, 122b.....129b in a manner corresponding to the conversion mode of the converter 113 of the data transmission device 11 will be described. . For example, if the converter 113 of the data transmission device 11 uses the first method of forming the first image frame n3a and the second image frame 113b, the converter 154 takes the first pixels 1131a, n32a, ..., U39a and 16 pixels of the 24 bits of the two pixels 1131b, 1132b, ..., U39b, # as the corresponding first data 121a, 122a.....129a and the second data 121b, 122b..... 129b. The converter takes the remaining pixels of the first pixels u31a, 1132a, ..., 1139a and the second pixels 1131b, 1132b.....1139b as the corresponding first data 12〗, a, 122a .....129a and one of the second data 121b, 122b.....129b check the relevant information. It is emphasized that the bit position taken by converter 154 is the same as the bit position filled in by converter 13. Taking the first pixel 1131a depicted in FIG. 1E as an example, the converter 154 takes the lowest 16 bits of the first pixel 113匕 as the first data i21a′ and takes the remaining 8 bits as its check 17 201010436 Relevant information. The rest and so on. Assuming that the converter 113 of the data transmission device 11 uses the second method of forming the first image frame 113a and the second image frame 113b, the converter 154 takes the first pixels 1131a > 1132a.....1139a and the second, respectively. The red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B of the elements 113lb, 1132b, ..., 1139b are used as the corresponding first data 121a, 122a.....129a and the second Information 121b, 122b..... 129b. In addition, the converter 154 takes the first pixel 1131a, 1132a..... 1139a and the second pixel 1131b, 1132b.....1139b, the red sub-alliner R, the green sub-alcohol G, and the blue The other one of the sub-studies B is checked as one of the corresponding first data 121a, 122a, ..., 129a and the second data 121b, 122b, ..., 129b. It is emphasized that the choices made by converter 154 and converter 113 must be the same. Taking the first element 1131a depicted in FIG. 1G as an example, the converter 154 takes the red sub-alliner R and the green sub-alloy G as the first data 121a, and takes the blue sub-pixel B as the check-related data. . The rest and so on. After the converter 154 completes the conversion, the data receiving devices 15a, 15b, 15c can transmit the first data 121a, 122a.....129a and the second data 12lb, 122b.....129b to the user terminals 17a, 17b. 17c is displayed for viewing by the user. So far, the second part of the data transmission and reception system 1 has been described. As can be seen from the foregoing, each of the data source locations 101, 102 ..... 109 corresponds to a pixel at a certain position in the image frame. The data transmission device 11 fills in the data received at different time points according to the source of the data, and fills in the pixels corresponding to the position in the image frame. Since the data of each of the data sources 101, 102 ..... 109 is approximated, the amount of data to be transmitted by the data transmission device 11 can be greatly reduced by subsequent encoding or even compression. In addition, through the video streaming method, a multi-point to multi-point data exchange architecture can also be achieved, that is, the user can simultaneously monitor data at different data sources. Figure 2 is a second embodiment in accordance with the present invention. The second embodiment is a data transmission method which can be applied to a data transmission device such as the data transmission device 11 in the first embodiment. The data transmission method described in the second embodiment includes the following steps. First, step 201 is performed to receive a first data from a plurality of data sources. Next, in step 202, the method stores the received first data in a memory. Next, in step 203, the method forms the first data frame into a first image frame of a movie. Then, step 204 is performed to receive a second data from the foregoing data sources. Step 205 is performed to store the second data in the memory. The method then proceeds to step 206 to form the second image into a second image frame of the movie. Second Embodiment The method of forming the first image frame and the second image frame is the same as that of the first embodiment, and therefore will not be described. The second embodiment can again receive other data from the aforementioned sources, store the other data received, and form other image frames in the same way. Next, in step 207, the method encodes the video including the first image frame and the second image frame into a video stream file having a video bit stream format. Subsequent step 208 will determine if encryption is required. If it is decided in step 208 to encrypt the movie, the method performs step 209 to encrypt the movie, and then performs step 210 to transmit the video (ie, the encrypted video stream file) to a server in a video streaming manner. If the result of the determination in step 208 is that no encryption is required, step 210 is directly performed to transmit the video (i.e., the unencrypted video stream file). 19 201010436 In addition to the foregoing steps, the second embodiment is more capable of performing the first operation (ie, from the first aspect of the data source 101, 102, ..., ] to the server w 109 to the data transmission device u == All functions and operations of the second operation are generally known to those skilled in the art, and it is not described in detail as to how the second embodiment is based on the above-mentioned first aspect. The data transmission method described in the second embodiment can also be completed by an electric device 'when the data transmission device (4)-computer carries the computer program product and executes the plurality of instructions, the second embodiment can be completed.

All of the functions and operations, those skilled in the art, can directly understand how the third embodiment operates based on the first aspect of the above-described first embodiment to perform such operations and Wei, and therefore will not be described. The data receiving method described in the example can be completed by the manufacturer's data receiving device via a computer to load the computer program product = the light 5 玄电 month self-program product contains a plurality of instructions, the third real expansion can be completed Receiving method The aforementioned computer program products can be stored in 记录 recording media, such as read-only memory, flash memory, floppy disk, hard monument: take a pen drive, a tape, a removable disk, a CD, and a amp access (4) The library or the cooked stomach of this technology and any other storage medium of the same function. Knowing that the data transmission method and receiving method and device and the computer program software disclosed in the present invention are plural The data is corresponding to the pixel in a certain position in the image frame, and the pixel is located at a certain position in the position of the needle. The data transmitted by the source at different time points of 2010 20100436 are respectively filled in the image frame according to the source of the data. The pixel corresponding to the position. In other words, the data of the same relative position of the adjacent image frames is the data generated by the same data source at the adjacent time points. The same data source is generated at the adjacent time points. The value of the data is approximated, so the present invention is further processed by the technique of encoding and compression, and is transmitted without any special processing on the data. The data transmission method, device and data receiving method and device can reduce the amount of data and reduce the bandwidth. When the number of data sources increases, the effect of the present invention can be further displayed. For example, assume that there are 10,000 data sources. Each data source needs to transmit a piece of data at each time point. In general, 10,000 pieces of data need to be transmitted at each time point. The present invention can represent the data of each time point as a 100X100 image frame, and cooperate with the image. The transmission method is transmitted. As mentioned above, each pixel is 24 bits (that is, 3 bytes), and the amount of data at each time point is only 30,000 bytes. If 10 bits are transmitted in 1 second. The image frame (1 〇frames/sec) calculates 100,000 data per second. From this, it can be seen that the present invention can smoothly transfer a large amount of data in a short time. Since the present invention uses a video streaming method, which has a multi-point-to-multipoint feature, such as a videoconferencing conference, each of the data sources (e.g., each of the factory buildings) can also see each other's data. In addition, since the video streaming mode is a standard mode, it is compatible with the existing platform, and it is not necessary to specifically convert the format of the data. Accordingly, the data transmission method and apparatus, data receiving method and apparatus, and computer program software of the present invention can improve the defects of the prior art. The embodiments described above are only intended to illustrate the embodiments of the present invention, and to explain the technical features of the present invention 201010436, and are not intended to limit the scope of protection of the present invention. Any changes or equivalents that can be easily made by those skilled in the art are within the scope of the invention. The scope of the invention should be determined by the scope of the claims.
