The method of encoding text information tv


(57) Abstract:

Usage: in systems encryption television information, in particular in the closed-circuit TV systems for the transmission of text information with authorized access. The inventive read the text, is converted into a video signal obtained in an image of text, which is reproduced on the monitor with subsequent correction of the text when an error is detected, and transmits the video signal of each letter of the text in the corresponding code combination and conversion of the video signal of each letter of text in a code combination is carried out in accordance with the current program number encryption, RAM, determined by the number of repetitions of the letters in the text, moreover, when the number of repetitions of each letter in the text smaller specified number of encryption programs current program number encryption is defined as the set of code combinations corresponding letter of the text and the number of repetitions in the text, and in excess of a predetermined number of encryption programs - as a set of code combinations corresponding letter of the text and the remainder from dividing the number of repetitions of this letter by the specified number of encryption programs, what if they match, the result of the comparison is converted into an analog signal, which are synchronized to the received image of the text. 2 Il. 73 With

FIELD: technology for displaying media streams.

SUBSTANCE: invention includes: conducting repeated multiple control and detection of launching events during output of main media stream; and on detection of launching event it is determined, which ones of one or more several additional media streams are related to launching event; for each related additional media stream it is determined, whether each related additional media stream is supposed to be outputted synchronously or asynchronously with main media stream; and iterative (repeated) output is conducted of each related additional media stream either synchronously or asynchronously with main media stream in accordance with results of previous detections. Synchronous additional media streams are outputted simultaneously with main media stream. Asynchronously outputted additional media streams pause the main media stream during their output and finish any additional media streams being outputted at current moment.

EFFECT: provision of timely assistance to individuals with impaired sight or hearing.

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a display control device/method, where a subtitle forced display function is implemented based on a timed text markup language (TTML). TTML data in which predetermined attribute information pertaining to subtitle forced display is described in a tag defining an element of text is used. At a content playback side, control is performed based on the predetermined attribute information in the TTML data, in such a way that characters based on text data designated by the tag in which the attribute information is written are displayed on a display unit regardless of whether subtitle display is ON or OFF. Owing to such a configuration, text data used as a predetermined text element from among text elements (text data used as subtitles) within the TTML data can be displayed regardless of whether subtitle display is ON or OFF.

EFFECT: display method with a subtitle forced display function based on a TTML.

FIELD: advertising engineering using cable television systems.

SUBSTANCE: user multimedia terminal saves preset identification number of target group of viewers in its memory. Cable signal being transmitted incorporates identification numbers of target groups of viewers apart from video item presented in the form of digital video signal and accompanying primary audio signal. Application program of user multimedia terminal finds out if alternative audio accompaniment signal is present in cable signal and compares preset identification number with those contained in cable signal to determine audio accompaniment signal to be reproduced in given video item.

EFFECT: provision for saving preset number of target group of viewers in user multimedia terminal memory.

FIELD: access control systems.

SUBSTANCE: proposed signal processing method involves reception of digital input signal incorporating first component of scrambled signal and second component of scrambled signal; binding of input signal with detachable intelligent card unit for processing first scrambled signal component and generation of first descrambled signal which is internal with respect to intelligent card unit and for processing second scrambled signal component in case of response to first descrambled signal to generate second descrambled signal and to integrate first scrambled signal component of input signal and second descrambled signal so as to produce output signal; reception of output signal from intelligent card unit and processing of second descrambled signal to shape signal adapted for display.

EFFECT: improved control of access.

FIELD: television.

SUBSTANCE: television add-on is provided with inner software, allowing to observe interesting events, and allowing other peripheral devices to connect thereto. In particular, add-on has three components, necessary for dispensing its basic functions: hardware, operating system and resident application. Each component provides separate set of application interfaces, which allow the application to query and direct hardware for performing certain functions, determine events observed by operating system, observe events taking place in resident program.

EFFECT: broader functional capabilities.

FIELD: technology for protecting audio/video data during transmission.

SUBSTANCE: during distribution in encrypted form of data between distribution center and at least one user module, instead of transferring information necessary for decryption simultaneously with aforementioned data, this information is grouped into file of decryption data which contains also data, determining access conditions for aforementioned audio-video data. This file is stored independently of aforementioned data and can be utilized both in case of immediate and delayed utilization of data.

EFFECT: possible distribution of audio-video data to all possible intermediaries while providing control over number of uses of these data.

FIELD: television with paid subscription.

SUBSTANCE: parameters of decoder operation depend on receipt of EMM messages of at least one preferred operator. Under certain conditions aforementioned decoder should enter waiting mode. In the case when user mainly receives transmissions of operator requiring no confirmation of user rights, decoder receives no further renewing EMM messages. If needed to transfer decoder to waiting mode following operations are performed: switching of decoder to channel of preferred operator, receipt by decoder from subscription control center of EMM messages and their processing, determining of completion of full cycle of receipt of EMM messages and transferring to waiting mode.

EFFECT: guaranteed correct functioning of paid television system while decoder client during extended time is not used for receipt of paid channel transmissions.
