Interactive video equipment and method for applying subtitles to image by means of said equipment. RU patent 2278479. |
|
FIELD: technology for applying subtitles for interactive video equipment, in particular, interactive video equipment and software method for applying subtitles, used in current video equipment. SUBSTANCE: control level of interactive video equipment receives information from user about subtitles necessary to be generated, in the coder of interactive video equipment on transferring assembly following stages are performed: receipt of information about subtitles from control level and following generation of subtitle image on transparent background in accordance to aforementioned received information; application of aforementioned image of subtitles to digital service image before encoding, sent from transferring node, with production of digital image, mixed with image of subtitles, and encoding of aforementioned mixed digital image with its following transmission to remote node. EFFECT: simplification of used technical means, decreased cost of system, simplified generation and application of subtitles. 2 cl, 4 dwg

![]() In the method for providing video data stream transfer service, server determines, whether filling is less than threshold value, or not less, than second threshold value of service, while filling represents amount of data, filling queue generation buffer in a terminal, while first threshold value is less than second threshold value. If the filling is less than first threshold value, than server provides data stream transfer service at predetermined bit transfer speed of service, which is less than current bit transfer speed of service. If the filling is equal to or greater than second threshold value, then server provides service of data stream transfer at predetermined service data transfer speed, which is greater than current bit transfer speed of service. |
![]() Interface of global WAN network is emulated for IP datagram over original remote interface of adapter and simple IP datagram transfer function is added between global WAN network interface and original Ethernet network interface in accordance to protocols stack. Therefore, system for controlling local network of digital television system performs IP connection to systems for controlling local area networks LANs of other digital television systems, then datagram is transformed to transport packets and transferred jointly with other transport packets via one and the same channel. |
![]() Method includes performing transmission to receiver-decoders through broadcasting system of a command, ordering receiver-decoders to perform an action; when command is receiver, identifier of command stored in current command is compared to identifiers of commands stored in memory of current decoder-receiver; aforementioned action is only executed in case when command identifier is not stored in memory. |
![]() Method includes transmission of digital signal, having additional data flow, appropriate for compressed video images and data flow, appropriate for at least multimedia application, and also service signals, meant for controlling aforementioned data flows, service signals is determined, appropriate for series of synchronization signal, including series, meant for assignment of multimedia signal, meant for recording execution parameters of aforementioned assigned multimedia application, after that multimedia application is loaded and multimedia application is initialized with aforementioned execution parameters. |
![]() Transfer system for transfer of transport flow of MPEG-2 standard from transmitter 10 to receiver 14, having check channel 16, along which receiver 14 can transfer selection criterion for selection of information blocks of MPEG-2 standard to transmitter 10, transmitter 10 has selector 38, which receivers required criteria and then filters information blocks in accordance to these criteria prior to transfer. |
![]() Device has blocks: first interface block, providing receipt of data about switching of programs by subscriber, electronic watch block, first memory block for archiving data about time of viewing of each selected program, second memory block, containing electronic addresses of broadcast companies, block for rearranging data about viewing time, processor, forming packet of data about which TV program and time of its viewing, third interface block, providing output along phone network of data about viewing time of each TV program to server of company, which broadcast current TV program. |
![]() Device has scaling block, two delay registers, block for forming pixel blocks, buffer register, block for calculating movement vectors, two subtracters, demultiplexer, enlargement block, pulsation filtering block, mathematical detectors block, multiplexer, reverse scaling block, as a result of interaction of which it is possible to detect and remove some series of TV frames from programs, which cause harmful effect to viewer, specifically pulsations of brightness signals and color signals with frequency 6-13 Hz. |
![]() Proposed local network 10 has subscriber leads 21 coupled with cabletelecasting head station 11 in desired carrier band. Network 10 also has noise suppression unit 21 whose input 24 is connected to leads 21 and output, to station 11. Unit 23 has band filters 28 - 31 connected to input 24 and using different passbands and transducers 32 - 35 designed for comparing output signal level of respective filter 28 - 31 with preset reference level and for feeding comparison result dependent logic signals to logic control unit 36 that functions to find out if these signals comply with conditions stored in unit 36 so as to convey control signal to unitized interlocking circuit 26 inserted in separate line 25 used to transfer signals from input 24 to output 27. Circuit 26 passes signals when logic signals received by unit 36 meet conditions stored therein. |
![]() System is made with possible reversed transfer of signals to local networks, included in system, back to main station of system in preset range of carrying frequencies, system has means for controlling interference, which include detection means, which are made with possible comparison of signals power level to one preset control level, and with possible generation of logic signals, memory devices, and also means in main station of system, using which information stored in memory means of local networks can be queried for transfer to main station for estimating this information at main station. |
![]() Device has decoder for receiving transmitted data, data-processing system and memory, while data-processing system stores data of user profiles, related to parameters or preferences of multiple users of terminal. Also, user profiles match terminal operation modes, and profiles data include data about priorities, pointing out rights of each user for using terminal resources. |
