Description

The invention relates to the field of television (TV), in particular to devices for receiving digital interactive television broadcasting signals, and may find application in the implementation of digital TV broadcasting in Russia, since the application of this invention will allow using digital interactive TV broadcasting subscriber receivers based on remote control and on-screen user menu, to control household electronic devices at home or office (home cinemas, music centers, air conditioners, refrigerators, microwave ovens, food processors, washing machines, dishwashers, etc.) by programming these devices, i.e. asking them programs and operating modes for any period of time using the technology of "smart home".

This function, provided by the proposed device, will allow you to implement additional functions that are attractive to users, increase the demand for subscriber receivers of digital interactive TV broadcasting and thereby accelerate the transition to digital interactive TV broadcasting. At the same time, the function of controlling household electronic devices will be carried out without the help of a personal computer, on the basis of digital interactive TV broadcasting receivers, the cost of which is 10-15 times lower than the cost of a personal computer. This circumstance is of vital importance for domestic digital TV broadcasting, which can become widespread only if it offers users new, attractive functions for them that were not previously provided by analogue TV broadcasting.

A device for subscriber reception of digital TV broadcasting signals, including a central processor, a system bus, a bus controller, a tuner, a demultiplexer, a video decoder and a sound decoder.

Data on the specified device is contained in the book: B.A. Lokshin. “Digital broadcasting - from studio to viewer.” Moscow, Cyrus Systems Publishing House, 2001, p. 287, Fig. 11.8.

In the process of receiving digital TV broadcasting signals using this device, the received multi-program digital TV broadcasting signal from the tuner output is fed to a demultiplexer that extracts the selected TV program from the multi-program digital TV broadcasting signal. The selected TV program is decoded by a video decoder and an audio decoder, which decompress the image and sound signals compressed in transmission in accordance with the MPEG-2 standard. Next, the decompressed digital video and sound signals are fed to the input of a digital TV receiver, or, after analog-to-digital conversion, to the input of an analog TV receiver. All of these units operate under the control of the central processor and exchange signals with the central processor via the system bus. The order of signal exchange between the blocks is also determined by the central processor and is carried out using a bus controller operating under the control of the central processor.

A disadvantage of the known device is that this device does not provide control of household electronic devices at home or office, i.e. programming these devices with the issuance of a program and an operating mode for any period of time using the technology of “smart home”.

The closest in technical essence to the claimed technical solution is a device for subscriber reception of digital TV broadcasting signals, including a central processor that controls all the units of the device, a system bus controller that converts control commands received from the central processor into signals transmitted to the device blocks via the system bus, as well as the manager of the procedures for exchanging signals on the system bus between the units of the device, as well as between the central a processor and units of the device, the input of which is connected to the output of the central processor, a demultiplexer that extracts from the tuner output of the multi-program digital TV broadcast signal the TV program selected by the subscriber, a video decoder that decompresses image signals compressed in accordance with the MPEG-2 standard to transmission, the input of which is connected through the system bus to the output of the demultiplexer and to the output of the system bus controller, and an audio decoder performing decompression th audio signals, compressed in accordance with MPEG-2 standard for transmission is input via a system bus is also connected to the output of the demultiplexer and the output of the system bus controller.

The disadvantages of this device are related to the inability to control household electronic devices at home or office, i.e. programming these devices with the issuance of a program and an operating mode for any period of time using the technology of “smart home”.

The absence in this device of such a function, which was not previously supported by the receiving devices of analog TV broadcasting, reduces its attractiveness for users and, thereby, slows down the transition to digital TV broadcasting.

The basis of the invention is the creation of a subscriber device for receiving digital TV broadcast signals, which makes it possible to control household electronic devices at home or office, i.e. programming these devices with the issuance of a program and an operating mode for any period of time using the technology of “smart home”.

This problem is solved using a digital TV broadcast signal subscriber’s device, including a central processor that controls all the device blocks, a system bus controller that converts control commands received from the central processor into signals transmitted to the device blocks via the system bus, and also controls procedures for exchanging signals on the system bus between the units of the device, as well as between the central processor and units of the device, the input of which is connected to by the central processor, a demultiplexer, which selects from the composition of the multiprogram signal of digital TV broadcast received from the tuner output a TV program selected by the subscriber, a video decoder that decompresses image signals compressed in accordance with the MPEG-2 standard on the transmission, the input of which is connected to the system bus the output of the demultiplexer and the output of the system bus controller, and an audio decoder that decompresses audio signals compressed in in accordance with the MPEG-2 standard for transmission, the input of which through the system bus is also connected to the output of the demultiplexer and to the output of the system bus controller, and the first interface unit is additionally introduced into the device, which provides data from the system bus about the appearance of the user control menu on the TV screen household electronic devices, i.e. about the beginning of the implementation by the subscriber of the programming of these devices, the input of which through the system bus is connected to the output of the central processor, the electronic home appliances control processor, which receives data on the household electronic devices control commands implemented by the subscriber using the on-screen menu, and generates the electronic home appliance programming commands, whose input is connected through the system bus to the output of the first interface unit, and the second input to the output of the formation unit Omand, the first memory block containing a list of types of programmable household electronic devices, the first input of which is connected through the system bus to the output of the processor for controlling electronic household devices, and the second input is to the output of the second interface block, by means of which the specified list of programmable types is replenished and changed electronic household devices, a second memory unit containing a set of control protocols for each of the existing electronic household devices (all known types of devices triads of all known manufacturers), the first input of which via the system bus is connected to the output of the processor for controlling electronic household devices, and the second input is connected to the output of the third interface unit, by means of which the specified set of protocols for controlling electronic household devices is replenished and changed, the third memory block, containing a list of modes and frequency ranges of radio communications with electronic household devices, the first input of which is connected to the processor output through a system bus control of electronic household devices, and the second input - to the output of the fourth interface unit, by means of which the specified list of modes and frequency ranges is replenished and changed, a command generation unit generating control commands for electronic household devices, the first input of which is connected to the output of the first memory block, the second input is to the output of the second memory block, the third input is to the output of the third memory block, and the output is to the second input of the processor for controlling electronic household devices, the fifth interface unit receiving commands from the control of electronic household devices to control these devices, the input of which via the system bus is connected to the output of the electronic household control processor, and a radio modem whose input is connected to the output of the fifth interface unit and the output to the transceiver antenna.

The essence of the proposed device is as follows.

Each time a subscriber uses a remote control and an on-screen menu to enter a command to control an electronic household device, the data implemented by a subscriber through a system bus is sent to the first interface unit 6 and then to the first input of the electronic household devices control processor 7. The control processor electronic household devices 7 extracts from the composition of the received data data on the type of electronic household device (home theater, refrigerator, food processor, etc.) and on the system bus it outputs this data to the input of the first memory block 8, which compares the data with its list of electronic household devices and coincides with a part of the electronic household device control command containing information about the type of device to the first input of the command unit 14 At the same time, the processor for controlling electronic household devices 7 via the system bus provides data on the type of electronic household device to the first input of the second memory unit 8, which activates the same memory in which the control protocols for each of the electronic household devices of this type are located, and starts enumerating the specified protocols, each of them issuing them to the second input of the command generation unit 14. At the same time, the electronic household devices control processor 7 issues a command to the third block via the system bus memory 9 at the beginning of the process of enumerating modes and frequency ranges of radio communications with electronic household devices. The third memory unit 9 in turn outputs the data of each of the modes to the third input of the command generation unit 14. The search modes carried out by the second and third memory blocks are synchronized by the processor for controlling electronic household devices 7 using commands transmitted via the system bus. Receiving data from the first, second and third memory blocks, the command generation unit 14 at each step of the synchronized enumeration generates an electronic home appliance control command and issues it to the second input of the electronic home appliance control processor 7, which converts it into the form necessary for issuing to the system bus, and on the system bus issues to the input of the fifth interface unit 15, which issues the specified command to the input of the radio modem 16. The radio modem 16 through the transceiver antenna issues a control signal to ether. The above procedures are performed at each step of synchronized enumeration until the type of electronic household device, control protocol, radio frequency mode and frequency range match the type, control protocol, radio frequency mode and frequency range supported by the electronic household device located in the apartment or office . In this case, the indicated device generates a response signal, which is received by the radio modem 16 and is transmitted via the system unit to the first input of the processor for controlling electronic household devices 7. Thus, a connection is established between the subscriber receiver and the electronic household device, and then the subscriber receiver transmits to the electronic household device control data generated in accordance with the technology of "smart home".

All of these blocks are implemented on the basis of programmable industrial modules, mass-produced by many companies. So, the processor and the command generation unit can be implemented on the basis of AT90S8535-8PI programmable processor modules manufactured by Atmel, the first, second, third, fourth and fifth interface blocks - on the basis of Altera EPM7128ATC100-12 interface modules, memory blocks - based on Flash modules - Am29LV008B memory manufactured by AMD; radio modem - based on XS200 processor manufactured by SAGEM.
