Use: for digital TV broadcast.

Known subscriber device receiving signals of digital terrestrial broadcasting, including the Central processor, system bus, bus controller, a tuner, a demultiplexer, a video decoder and audio decoder.

Data about the specified device are contained in the book: Baiocchi. Digital broadcasting - from the Studio to the viewer.- M.: Publishing company "Cyrus System", 2001, str, RES.

In the process of receiving digital TV signals broadcast by using this device adopted multi-program signal of the digital TV broadcasting output from the tuner is fed to the demultiplexer emitting from the structure of multi-program signal digital TV broadcast selected by the subscriber TV program. Selected TV program is decoded by the video decoder and the audio decoder performing decompression of image signals and sound, compr tsirovannykh on the transfer in accordance with the MPEG-2 standard. Next decompensirovanny digital video / audio signal fed to the input of a digital TV receiver or, after analog-to-digital conversion on the analog TV receiver. All of these units operate under the control of the Central processor and communicate with the Central processor through the system bus. The exchange of signals between the units is also determined by the CPU and is using the bus controller operating under the control of the Central processor.

A disadvantage of the known device is that this device does not provide the provision of television companies broadcasting programs which are in digital mode, information about what kind of transmission in the composition of this TV program and for a time watched the subscriber, not allowing, thus, the television companies to calculate the next audience ratings of broadcast transmission, as well as the rating of a TV program as a whole and to build optimal on the basis of these ratings financial policy in the field of digital TV broadcasting.

The closest in technical essence to the claimed technical solution is a subscriber device receiving signals of digital terrestrial broadcasting, including the Central processor, capable of managing all the block of the AMI device, the controller system bus that converts control commands received from the Central processor, the signals transmitted block device on the system bus, as well as managing the procedures for the exchange of signals on the system bus between the blocks of the device, as well as between the Central processor and the device's blocks, the input connected to the output of the Central processor, the demultiplexer engaged in the selection of the composition obtained from the output of the tuner multi-program signal digital TV broadcast selected by the subscriber television program, the video decoder performing decompression of image signals, compressed in accordance with MPEG-2 transmission, the entrance of which is through a system bus connected to the output of the demultiplexer and output controller system bus, and the audio decoder performing decompression of audio signals, compressed in accordance with MPEG-2 transfer, entrance through which the system bus is also connected to the output of the demultiplexer and output controller system bus.

The disadvantages of this device are related to the inability to provide television companies broadcasting programs which are in digital mode, information about what kind of transmission in the composition of this TV program and during the time looked subscriber, that does not allow television companies to calculate audience ratings of broadcast transmission, as well as the rating of a TV program as a whole and to build optimal on the basis of these ratings financial policy in the field of digital TV broadcasting. The absence of this device, this function makes the TV company to obtain baseline data to determine the ratings of the transmission as part of a TV program, as well as the rating of the overall program to resort to various sample surveys and questionnaires, data which allow only very imprecise and approximate, and often simply incorrect ratings, because inevitably a small number of respondents subscribers (non-representative sampling), the possibility of inaccurate and incorrect answers, the influence of the wording of the question on the content of the response, and other adverse factors associated with the specifics of the sociological survey as a method of obtaining information.

The basis of the invention is to obtain the subscriber device receiving the signals of digital TV broadcasting, enabling television companies broadcasting programs which are in digital mode, to periodically obtain feedback channel accurate information on what transmission and for a time watched every subscriber, calculating daleena the basis of the full amount of data received from the subscriber devices, accurate information about the audience rating of each transmission as part of a TV program, as well as the rating of a TV program as a whole.

The implementation of this invention means the transition from the estimates made by the broadcasters audience preferences in the field of TV programs and broadcasts, carried out on the basis of sample surveys and questionnaires, direct and precise measurement of these preferences across the audience of digital terrestrial broadcasting and, accordingly, the transition from an estimate of the ratings of TV programs and broadcasts, based on the processing results of surveys and questionnaires, to their immediate accurate calculation. This transition will allow the television companies to carry out their work on the basis of a well balanced financial and investment policy, i.e. to invest in those transmission, audience rating, accurately measured using functions provided by the proposed device is maximum. Precise knowledge of the audience rating of the transmission will also allow broadcasters to optimally shape the pricing for advertisers, shaping rates for advertising in various programs in strict accordance with the rating of these programs, and to obtain, thus, the optimal revenue for further investment in the development of cifrovoj the TV broadcast.
