Description of the Invention (ί) Inventive Jaw Field The present invention is generally related to broadcast data, and more particularly to data broadcast error sampling. BACKGROUND OF THE INVENTION The occurrence of broadcast materials has increased. In addition to the normal analog broadcast ', digital broadcasts also occur. Analog broadcasting is used for standard television. Digital broadcasting is now used in television, audio and electronic magazines. Digital broadcasting allows mass transmission of anything that can be converted into digital form. The transmission of 'digital data' is usually done on a one-on-one basis. For example, one computer sends over the Internet—email messages to another computer. If the receiving computer has a problem receiving the data, it can tell the transmitting computer to send it again. This is not a serious problem. There are also cases where digital data may be transferred to some computers. For example, a web server that handles 80 user computers on a local area network. This is not a bad problem because the few receivers can contact the transmitter and make the wrong data retransmit. The transmitter can easily send data to one or several receivers. However, this situation occurs in a one-to-many situation such as a computer transmitting digital data for a speech, and it may be difficult for a transmitter to receive a request for retransmission of erroneous data because it may be made to the required amount. It is difficult to track all the receivers and the missing data. Therefore, it is not easy to broadcast materials on the ground in a one-to-many format. In general analog broadcasting, errors are not the main consideration. Gastric errors can cause unintended flickers on the TV screen. However, digital stomachs contain far more than TV broadcasts and have higher requirements for reliability ° 3 _____ (Please read the precautions on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper scale is applicable to the Chinese Goods Standard (CNS) A4 specification (210X297 mm) 449983 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _B7 _ V. Description of the invention (2) The only one currently used to try to increase the reliability of broadcasting Is for retransmission. This is very inefficient for broadcasters. The present invention addresses these and other issues. The invention relates to the incorrect sampling of data broadcasting. One embodiment includes a system. The system consists of a master station, multiple receivers, and one or more sampling stations. The master station broadcasts the data to one or more predetermined areas β. A plurality of receivers are located in each predetermined area and receive the broadcasted information. One or more sampling stations are located in a predetermined area and receive the same information broadcasted by the master station, and then transmit the received information back to the master station. The invention encompasses systems, methods, and sampling stations in a variety of categories. There are other embodiments, viewpoints, and advantages that will become more apparent after studying the drawings and detailed descriptions.

These examples are explained in sufficient detail to enable those skilled in the art to implement the invention, and it should be understood that other examples can be used without departing from the spirit or scope of the invention. 7: You can make logical, mechanical, electronic, and other changes. Therefore, the following detailed description is not intended to be viewed in a limiting sense. The scope of the present invention is only defined by the scope of the attached patent application. Participate Consider FIG. 1, which shows a system according to an embodiment of the present invention. The system includes a master station 101, a plurality of receivers 103, and one or more sampling stations 104. The master station broadcasts information to one or more stations. Multiple predetermined areas 102. The master station may be a data provider or broadcaster. Information may be digital or analogous. The predetermined area may be a state, county, or any other type of geographic area. The predetermined area may be Receiver types such as computers using modems. They can be made to make the area small enough for the receiver to have similar reception in that area, but large enough to make the number of sampling stations required very small. A plurality of receivers are placed in each predetermined area. 5 This paper size applies to the Chinese national standard (CNS > M size (210X297 mm).

Inventory (4) and receive information Take one or more of each pre-determined area The sample station receives information and transmits the reception quality to the master station. The sampling station receives the same broadcast information as the receiver. Therefore, the reception of the sampling station is similar to that of the receiver. The reception quality can be the percentage of the received data, Or the acceptability of information. The acceptable quality degradation of information can vary with the type of information being broadcast. The acceptable quality degradation of video calls may be less forgiving than the pay-per-view viewing system. The second type of information about reception quality can be anything the master wants. Another embodiment of the present invention is a sampling station 200 and is shown in FIG. The sampling station includes a sampling station receiver 202 and a comparator 203. The sampling station receiver receives broadcast material from the signal source 201. The sampling station receiver 202 receives data similar to other receivers. The comparator 203 compares the broadcasted data with the expected data and generates a report for transmission to the signal source. The material being broadcast can be digital or analog. The expected information is more reliable than the material being broadcast. The expected information can be correct. The sampling station 200 may be given this information in advance. The expected data may also be data received by a more reliable method than broadcasting. For example, the data may be transferred from the signal source 201 to the sampling station 200 by a direct link. The report contains information about the quality of the reception and is transmitted to the source. The report may contain a percentage of false data compared to the total broadcast volume. Alternatively, the report may contain a decision as to whether the source should rebroadcast the material. It should then be up to the source to decide whether to provide the revised information. Referring to FIG. 3, a method according to an embodiment of the present invention is shown.

The master station can be a data broadcaster or a data provider. The master station can also provide data And data broadcasters. The data can be digital or analog. The data is received at the sampling station (step 302). The reception of the sampling station is similar to that of the receiver in the area. The data is Compare with the expected data (step 303). The expected data can be error-free data or more reliable data. For example, error-free data can be data transmitted to the sampling station before broadcasting, or can be For more reliable data that is directly transferred from the master station to the sampling station. The evaluation of the erroneous data is determined by comparison (step 304). The erroneous data may include missing, missing or incorrect data. Then, the master The station was informed of the evaluation of the incorrect information ( (Step 305). The master station can be informed of the evaluation of the erroneous data by being notified of the erroneous data or the percentage of the lost data. Alternatively, the master can be informed of the retransmission. The retransmission decision can be based on the evaluation of the erroneous data Whether it is above the acceptable threshold (step 306). This can be determined by the sampling station or the master station. The acceptable threshold can be determined according to the implementation requirements. For example, the acceptable threshold can be wrong information The data can be retransmitted to all possible receivers or to one or more specific areas. The previously described method enables the data broadcaster to receive information about the reception quality that is sufficiently representative of the reception quality of a typical receiver. This method enables a data broadcaster to receive the data in a manner that does not occupy too much of its resources. Furthermore, the method enables the broadcaster to retransmit data to areas where retransmission is only required. Referring to FIG. 4, it is shown that according to the invention One embodiment is a computer-readable medium 400 having a computer-executable instruction.
