The invention relates to communications, and more particularly to a method of transmitting radio signals from emitters located at the transmitting radio signals of radio objects, including moving, and receive and retrieve information in an information ground points receiving the radio system. Such systems include, in particular, radio navigation and radar systems, radio, radio equipment, radio results the surface of the Earth and other [Radio system / Y.M. Kazarinov and other Ed. by Y.M. Kazarinova. - M: CI "Academy", 2008, p.7]. The transmit radio signals at specified intervals and, if necessary, with the set of individual characteristics for a particular transmitting the radio signal of the radio object. The implementation of the method will allow, in particular, to measure the spatial coordinates of the transmitting radio signals of radio objects, to facilitate the appropriate extraction system information, to increase their technical and economic efficiency, taking into account all components affecting the cost and technical performance.

Known methods of transmitting and receiving radio signals to and retrieve information in the information system used, including, for measuring the coordinates of radio objects and is based on applications to the Institute angular, rangefinder, differential and total-ranging and combined methods of determining the location of the object with the amplitude, time, frequency, phase and pulse-phase methods of measurement of parameters of radio Patents of the Russian Federation№№2018855, 2115137, 2258242, 2264598, 2309420, 2325666, 2363117, 2371737, 2378660; the Basics of testing aircraft / H.

Methods of evaluating the effectiveness of the positioning of the radiation sources. - M.; "radio engineering", 2008, mainly 5]. The known methods have various disadvantages, such as the need for mechanical movement of the antenna system, the inability to uniquely determine the coordinates of the object, the need for a priori information about the location of the object, the need for common synchronization of transmitting and receiving radio signals of radio objects, lack of reliability. According to the criterion of minimal sufficiency, the closest one is the method of transmitting and receiving radio signals to and retrieve information in the information system under the patent RU №2453995.

This is achieved in that, in particular, does not require total synchronization of the combined transmitting and receiving radio signals of radio objects. This simplifies the determination of the spatial coordinates. Spatial coordinates are determined by indirect measurement using simple expressions that depend on the measured moments of the time of reception of radio signals in the information ground points receiving the radio system. The method eliminates the ambiguity of measurement of coordinates.

SUBSTANCE: invention relates to a transmitting device and a receiving device, particularly a high definition multimedia interface (HDMI). A disc writing device 210 transmits function information indicating that a data transmission module (I/F 213 high-speed data line) is configured to transmit data to an external device through a data channel composed of a backup line and rapid connection detection line of an HDMI cable 350 to a television receiver 250 through a home electronic device control line, which an HDMI cable 350 control data line. A television receiver 250 receives function information such that it can be determined if the disc writing device 210 is an eHDMI-compatible device, and if so, a compatible transmission format (application) can be recognised. Also provided is the capability of transmitting function information of the television receiver 250 to the disc writing device 210.

EFFECT: enabling an external device to recognise information relating to its data transmission module if said external device includes a data transmission module configured to transmit data through a data channel composed of a pair of differential transmission channels included in the transmission channel.

SUBSTANCE: invention relates to network communication technology and specifically to data transmission based on slide detection. The technical result is avoiding the downloading of data of no interest to a user, i.e. corresponding to a message cell that enters into and then slides out of the screen quickly, which considerably reduces traffic of a mobile device user. The method includes, when it is detected that a time line scrolls on the screen of a user device, recording, by a message client application, a message cell displayed on the screen (step 101), and determining, by the message client application, whether the message cell is still displayed on the screen after a predefined time interval (step 102); if the message cell is still displayed, downloading, by the message client application, data corresponding to the message cell from a message server (step 103).

EFFECT: also disclosed is an apparatus for data transmission based on slide detection, which includes a detecting module, a recording module, a determining module and a downloading module.

SUBSTANCE: invention relates to communication systems and specifically to systems of digital radio communication means, and can be sued to exchange data and audio and video information between aerial, ground, water-borne and space objects. The modular on-board system of digital radio communication means comprises 2N crates consisting of two control switching modules and two computing modules, 4N-channel communication modules comprising digital-to-analogue and analogue-to-digital converters and a power amplifier, made in a single unit spatially spaced apart with the crate.

EFFECT: improved energy-efficiency and reliability of digital radio communication.

SUBSTANCE: data transfer device meant for realization of data transfer method contains at least one transferring device and one receiving device, block for determining characteristics of one or several data transfer channels for several methods for transferring data and/or several parameters of data transfer of one or several methods for data transfer and block for selecting method for data transfer with certain parameters of data transfer according to result of said determination, while determination block is made with possible determination of speed of change of data transfer channel, and selection block is made in such a way, that dependently on said speed of change it selects mode with suppression of interference in receiver or transmitter.

EFFECT: higher quality.
