ASK is the most important technical division for television. It is filled with professional equipment, taking up most of the space in the control rooms television path for processing video and sound, as well as special devices for recording and playing them, also directly connected with the hardware-studio complex. From him composition Can highlight several full-fledged independent departments, such that on some TV channels there will be isolated. But for simplicity service and ease of use, usually they are united in one big one complex of hardware.
Overview of the hardware and studio complex
TV studio main base or even foundation for everything content production, because creation of video material in sufficient for broadcast volume is just impossible. Studio shooting require large technical capabilities, which is feasible when included in hardware-studio complex. Regardless of the scenery, there is always . She constantly in the spotlight, because in it something happens that millions of viewers will soon see. And for this they create around her Technical buildings with processing video and, hardware for signal transmission to the transmitting center, monitoring rooms with director's and sound engineering consoles, video recording and playback equipment.
Television studio with equipment
It can be compared with a theater hall. The scenery is installed in that part of the studio that all television viewers will see, like on stage. Against theater stage there are people sitting in the hall, and on television are worth .
TV stage Mixer allows the video director to choose the camera that will be on air now, this is how it is done. Sound mixing console controlled by sound engineer and defines which sound will be broadcast, from a studio or from another source.
Video director and sound director mixing consoles in ASK IN technical hardware the video engineer has his own remote control and adjustments mainly for quality control video and the entire broadcast, as well as using an oscilloscope.
Technical hardware room in ASK Composition of the television studio and hardware complex
In order to Studio was not just a beautiful room, but a fully functional object for broadcasts, it is filled technical equipment included in composition of the studio hardware unit. There are TV companies different types : private and public, small and large, regional and federal, etc. Depending on the type of television, their components will also be different. Including composition of the hardware-studio complex will be larger and more equipped in major television company than on a small one.
Plan of the television studio complex. Production studio content divided as much as possible between several hardware, installed near the studio, for comfort.
ASB – hardware studio unit
Judging by ASK plan all signals eventually flow into target audience(central control room), but still production center we highlight television programs ASB. In addition, it takes up the most space and resources. Technical hardware studio equipment, as well as technical personnel, perform tasks to provide creative personnel, everything you need for recording or live broadcast. Thus collaboration between creative and technical workers here are expressed more often than anywhere else on television.
Function of the hardware studio unit
The hardware-studio unit, both in terms of importance and volume, takes up a lot of space in the hardware-studio complex. Thanks to a large number equipment included in it, the use of other sources is almost not required.
- television signal development;
- from studio video cameras;
- switching, ranging and distribution of signals for their initial supply to and on the wall of monitors;
- a set of sources for applying skillful special effects to them, transforming and turning one frame into another;
- production of the program, management by the director of the production of the final, composite picture (frame) from different images and performances;
- monitoring of broadcasts and recordings, and sources for them;
- provision, and external communication with other television hardware.
Sound remote
The sound engineer has his own mixing console, but the operating principle is similar. Switching the audio channel begins by connecting the microphone to a long cable with a specific number. Next, the cable is connected to the audio socket in the wall, and from there it goes into the wiring closet. In the sound cabinet, you can do the switching manually, otherwise the cables with the same numbers go to the remote control. In the console, cables are connected to specific tracks, previously discussed with the sound engineer. Sound tracks can be combined with each other, or disconnected from the remote control output and used as listening.
Technical hardware
The video engineer's hardware differs from the video director's in the presence of video sources. Technical hardware designed for monitoring and configuring the video path. The director controls the cameras for the correct frame and the computers with other sources for the presence of the necessary content. Video Engineer's Task so that the quality from all sources meets all standards. Also, technical staff ensures the operability of all equipment and carries out timely preventive maintenance. To control video quality, sometimes subjective viewing of the monitor is not enough. For a more professional opinion, use an oscilloscope and others measuring instruments. In particular, black colors are clearly visible on the oscilloscope.
Central control room (CA)
The hardware room, small in area and quantity of equipment, is also part of the hardware studio complex. Performs the most important function throughout television - transmits the signal produced in ASB and AVZ to the end viewer. Of course, a TV channel from the target audience does not broadcast directly to every viewer. This is the task of the ORTPTs (public Russian television broadcasting center) or. TA is engaged switching any signals, both incoming and outgoing. Inbox signals are used on television to produce programs or to insert them into them. Outgoing the signals are basically the TV channel itself, transmitted by ORTPTS, or exchanged content between television companies. .

The hardware-studio unit is intended for the formation of TV programs or their fragments by recording or direct broadcasting and is usually considered as a complete independent technological unit. This view, of course, has a right to exist, but if you consider that programs of various types are usually created in ASB thematic area- music, news, etc., then the set of necessary technological equipment in the ASB should be both large and varied.
The proposed option for constructing a CRS is developed based on the concept that a CRS is component unified digital TV system of the company and part of the equipment, providing a wide range of technological capabilities of the ASB for organizing the most diverse and complex television broadcasts and recordings is located in other departments.
The main source of signals external to the ASB (SDI format) is the switching matrix of the Central Equipment Room (CAR). To select sources, the video director’s workplace has a central matrix control panel. It is also possible to connect a number of other external lines.
The main equipment of the ACS includes 4 cameras, however, cable communications and control equipment should make it possible to expand up to 6 - 8 stationary cameras. Studio video cameras are connected to base stations with a 26 pin cable - multicore system (triax systems are more expensive and their use is justified if the camera is located far from the base station - more than 100 m). The studio camera configuration includes: base station, camera adapter, control panel. The camera can be equipped with a 5-inch viewfinder. The base station includes all the necessary components and functions of the camera system, has an SDI output and provides high quality Images. The SDI video outputs of studio camera base stations are connected to the video mixer. Signals from external sources also enter the video mixer through distribution amplifiers. It is worth noting that all video signals entering the studio video mixer must be synchronized, only in this case can “pure” switching occur. The clock generator is installed in the AC; synchronization of the sources is carried out in parallel through distribution amplifiers.
The video switcher must have a sufficient number of SDI video signal inputs and several switching lines. The first of them - software - is designed to supply the selected video signal directly to the program output of the video mixer. Additional rulers provide a smooth change of video images. The mixer must have Tally outputs, which are connected to inputs of the same name on camera channels and system video monitors in the studio and engineering blocks (Ether signal), a switch (aux) - for dialing a video signal to the input of a title system or special effects processor that operates in GenLock mode, passing the video signal “through itself”. There are a sufficient number of titles and graphics output devices on the market. In fact, each company offers not individual devices, but platforms that are the basis for a whole group of character generators with different functional features. This approach allows you to configure a system that best suits the specific needs of the user. In addition, a thoughtful choice of the base model and additional options allows you to optimize the financial costs of the system for preparing titles and graphics, without overpaying extra money for unused functions.
To reserve the video mixer path, a matrix switcher (8*8) is used, the inputs of which connect the same sources as the video mixer.
The outputs of the mixer and switch are fed to an automatic bypass switch - when the signal from the mixer is lost, it automatically switches to the signal from the matrix. The second output of the mixer is connected to the input of the switch, which increases the flexibility of the technological use of the video path of the hardware room. In addition to matrix switchers, both video and audio equipment includes manual signal switching panels.
The output path signal is fed to the matrix in the AC and programs from the ASB are recorded to the video server in the AC; one of the outputs of the reserve switch is also connected to the central matrix.
A disk recorder is installed in the ASB (one input for recording, two independent outputs for playback). In any operating mode of the ASB - program recording or broadcast - the disk recorder and the central video server back up each other.
For visual monitoring of source signals and output programs, the ASB is equipped with color digital and analog monitors. As a monitoring system, it is possible to use a multi-screen processor with a sufficient number of inputs (for example, 8). Such a system can replace a monitor wall of several monitors with all service indication and audio signal control systems.
Sound equipment must also support the production of a wide variety of programs. Audio signals from the disk recorder and the AC matrix are connected to the sound engineer’s audio mixer; a cassette deck, CD player, etc. can be used as additional devices.

“, who is associated with the government of Tatarstan, called Archpriest Vsevolod Chaplin “nonentity.” Last night a post was published, which was a response to a speech on the radio station “Moscow Speaks”.
“The other day, Gabrelyanov, who criticizes Minnikhanov and Tatarstan, was joined by another nonentity. Archpriest Vsevolod Chaplin, forgotten by everyone, accused the President of Tatarstan of greed and the desire to profit from beer sales. This is in response to the recent proposal of the President of Tatarstan to Putin to only allow the sale of low-alcohol drinks at stadiums on matches," the post begins (spelling preserved) .

“No need to be disingenuous, no need to lie. IN in this case we are talking about elementary greed, about the desire to earn income not so much from sports, but from the sale of all sorts of drinks, good and bad,” Chaplin said yesterday on the radio station.
On July 20, at a meeting of the State Council for Physical Education and Sports, the head of Tatarstan Rustam Minnikhanov reported to the President of the Russian Federation Vladimir Putin, that during the World Cup in the republic they sold beer worth 89 million rubles. He also noted that no incidents or problems arose. Minnikhanov asked Putin to consider a more liberal approach to the sale of beer during football competitions. The head of the Republic of Tatarstan also added that, as a Muslim, he is ashamed to talk about beer, “but I care about our brothers, the Orthodox...”, he added.
Chaplin was surprised on the radio that “a man who seems to be a Muslim is raising this topic.” The archpriest believes that the Muslim clergy and the public should express their opinion on this matter. The Council of Muftis of Russia also protested the return of alcohol sales at sports facilities.
« We only stand for promoting the right, healthy image life"- RIA Novosti quoted the Deputy Chairman of the Council of Muftis of Russia Rushana Abbyasova .
The Hardware channel, which is associated with the office of the head of Tatarstan, calls Chaplin an odious figure, a person who knows nothing about economics, recalls his dismissal from the patriarchy, citing odiousness and outrageousness as the reasons, as well as statements in support of the famous fast food chain. The authors of the post accuse Chapliv of split consciousness.
"Chaplin is his own PR man and is ready to promote himself on any topic", the text of the post says.
“It seems that now he has reached the level where he is used as a critic of everything and everyone, who does not understand anything, but hides behind the authority of a clergyman,” the authors conclude the text of the message.
