Definitions

  • the present invention relates to a method for identifying a channel for viewer research from a video signal which is supplemented with channel identification data.
  • the invention also relates to a system for viewer research, comprising means for identifying a channel from a video signal supplemented with channel identification data.
  • the invention relates to channel measuring device comprising means for identifying a channel from a video signal supplemented with channel identification data.
  • Ratings of viewers of television channels are measured e.g. to evaluate how interesting the programs broadcast on different television channels are considered. This information interests both the producers of the television channels and the advertisers. For the producers of television channels, the viewer ratings tell what kind of programs are popular to watch. Thus, in the acquisition of new programs and in the planning of continuation to existing programs, one is more likely to end up in an arrangement in which the viewer ratings of programs to be broadcast remain as high as possible. On the other hand, different television channels compete with each other for the viewers, wherein many producers try to acquire programs which interest as many viewers as pos- sible. Also advertisers want to invest on advertisements to be broadcast in connection with such television programs which have many viewers who belong to the target group of the advertiser. Thus, in addition to the viewer ratings, the measurements are also aimed at finding various statistical data on the viewers, such as their age and/or sex distribution. In addition, particularly in connection with various regional programs, the aim may be to find out regional statistical data.
  • the arrangements of prior art are primarily based on the activity of selected viewers.
  • a group of viewers are given a measur- ing device, wherein these viewers enter, in the measuring device, data about the television channel they are watching as well as data about how many viewers are watching the program broadcast on this television channel.
  • the measuring device transmits the data to a measuring centre for collecting measurement data, normally by using a telephone connection.
  • the measuring centre compiles the data from the different devices and uses statistical mathematical methods to make a national and/or a regional analysis of the viewer ratings of the television channels to be measured.
  • the number and location of the measuring devices are to be selected so that the data obtained from the measuring devices would represent the viewer habits of a given geographical region as well as possible.
  • International application publication WO 00/70869 presents a method and a device for identifying a channel in viewer research by examining the video signal of the channel.
  • a digital signature is formed of the video signal, to be compared with a reference signature (e.g. a signature formed of a reference signal) to find out which channel is selected in a television set.
  • the reference signal can be generated by a sepa- rate tuner in which the selection of the channel is controlled on the basis of whether the signatures to be compared match or not.
  • the signature and the reference signal are formed of the video signal.
  • the system according to said publication has, for example, the problem that the content of the video signal normally varies to a great extent, wherein it may be difficult to find a suitable reference signal.
  • reference signals, or digital signatures formed of them are stored in the system, which requires a lot of storage capacity.
  • Arrangements are also known in which, at the broadcasting stage, the video signal is supplemented with information to be detected by a device for measuring viewer ratings connected to the viewer's set and using this information to identify the television channel being watched.
  • This supplemental information is included in such a part of the channel signal which is not displayed on the monitor of the receiver.
  • a problem in such an arrangement is, for example, that the signal to be broadcast must be supplemented with information which is only used for measuring the viewer ratings. This requires that auxiliary equipment is used at the broadcasting stage before the method can be applied.
  • the device for measuring viewer ratings must be connected to such a part of the receiver where this auxiliary infor- mation is included. This requires that the receiver has such an output connection from which the video signal can be lead to the device for measuring viewer ratings.
  • the invention is based on the idea that the measuring device is used to examine a video signal intended to be displayed on a monitor, by analysing the video signal of the channel or a video signal formed on the basis of information broadcast on the channel, to find out which channel is in question.
  • the analysis of the video signal can be made, for example, from a video signal output connection possibly provided in the receiver, or with a separate camera. When a camera is applied, it is trained on the video signal displayed on the monitor.

  • the present invention shows remarkable advantages over solutions of prior art.
  • To analyse the video signal there is no need to modify the receiver or the monitor. Because the measurement utilizes information which is independent of the measuring system and which is included in the video information in any case, the measuring arrangement according to the invention will not require any changes at the broadcasting end either.
  • the arrangement of the invention is independent of the transmission path and the transmission technology.
