Definitions

  • This invention relates generally to broadcasting data, and more particularly to data broadcast error sampling.
  • BACKGROUND Broadcasting data occurs increasingly today. Besides normal analog broadcasting, digital broadcasting is occurring. Analog broadcasting is used for standard television. Digital broadcasting is now being used for television, audio, and electronic magazines. Digital broadcasting allows the mass transfer of anything that can be converted to digital format.
  • the sending of digital data is done on a one-to-one basis. For example, one computer sending an email message to another computer over the internet. If the receiving computer has a problem receiving the data, it could tell the sending computer to resend it. This is not too significant of a problem. There is also the situation where the transfer of digital data would be to a few computers. For example, a network server handling 80 client computers on a local network. This is not too bad of a problem because the few receivers could contact the sender and have faulty data resent. A sender could easily resend data to one or a few receivers.

  • FIG. 4 shows a flowchart of a method according to an embodiment of the invention
  • FIG. 5 shows a diagram of a computer in conjunction with which an embodiment of the invention may be practiced.
  • the system includes a main station 101, a plurality of receivers 103, and one or more sampling stations 104.
  • the main station broadcasts information to one or more predetermined regions 102.
  • the main station may be a data provider or a broadcaster.
  • the information may be digital or analog.
  • the predetermined regions may be states, counties, or any other type of geographic region.
  • the predetermined regions may be types of receivers such as, for example, computers using modems. They may be made such that the regions are small enough so that the receivers have similar reception in the region but large enough so that the number of sampling stations needed are small.
  • the plurality of receivers are located in each of the predetermined regions and receive the information.
  • the one or more sampling stations within each predetermined region receive the information and convey reception quality to the main stations.
  • the sampling stations receive the same broadcast information as the receivers. Thus, the reception at the sampling station is similar to the reception at the receivers.
  • the reception quality may be a percentage of data received or acceptability of the information.
  • the acceptable degradation of the information may vary for different types of information being broadcast.
  • the acceptable degradation of a video phone might be less strict than the acceptability of a pay per view system.
  • the second information regarding reception quality may be any information that the main station would like to know.
  • Another embodiment of the invention is a sampling station 200 and is shown in FIG. 2.
  • the sampling station includes a sampling station receiver 202 and a comparator 203.
  • the sampling station receiver receives broadcast data from a source 201.
  • the sampling station receiver 202 receives that data similar to other receivers.
  • the comparator 203 compares the broadcasted data to expected data and generates a report to be transmitted to the source.
  • the broadcasted data may be in a digital or analog format.
  • the expected data is data that is more reliable than the broadcast data.
  • the expected data may be error free data.
  • the sampling station 200 may be given the data before hand.
  • the expected data may also be data received by a more reliable method than broadcasting. For example, the data could be transferred by a direct link to from the source 201 to the sampling station 200.
  • the report contains information about reception quality and is sent to the source.
  • the report may include a percentage of faulty data compared to the total amount broadcasted.
  • the report may include a determination as to whether the source should rebroadcast data. It would then be up to the source to provide corrected data.
  • the data is broadcast by a main station 301.
  • the main station may be a data broadcaster or a data provider.
  • the main station may also be a data provider and a data broadcaster.
  • the data may digital or analog.
  • the data is received at a sampling station 302.
  • the sampling station reception is similar to the reception of receivers in a region.
  • the data is compared to expected data 303.
  • the expected data may be error free data or more reliable data.
  • the error free data can be data sent to the sampling station prior to broadcasting or the more reliable data can be data transfered directly from the main station to the sampling station.
  • the measure of of faulty data is determined by the comparison 304.
  • the method permits the broadcaster to retransmit data to only those areas that need data retransmitted.
  • Broadcast data is received from a source 401.
  • the broadcast data can be digital or analog.
  • the source may be a data broadcaster.
  • the broadcast data is compared to expected data to determine if there have been any errors introduced 402.
  • the expected data can be error free data or more reliable data.
  • the error free data could have been sent before the data was broadcasted.
  • the more reliable data can be data sent directly from the source to a receiver. If errors are found 403, an error report can be transmitted or sent to the source 404.

Abstract

L'invention porte sur un échantillonnage d'erreurs en radiodiffusion de données. Dans une forme de réalisation, un système inclut une station principale, une pluralité de récepteurs, et une ou plusieurs stations d'échantillonnage. La station principale radiodiffuse des informations vers une ou plusieurs régions prédéterminées. Les nombreux récepteurs sont installés dans chacune des régions prédéterminées et reçoivent les informations radiodiffusées. Les stations d'échantillonnage sont installées dans les régions prédéterminées; elles reçoivent les mêmes informations radiodiffusées par la station principale et renvoient à celle-ci des informations concernant la réception.
