Production Control Room
The production control room (PCR) or studio control room (SCR) is the place in a television studio in which the composition of the outgoing program takes place. The production control room is occasionally also called an SCR or a gallerythe latter name comes from the original placement of the director on an ornately carved bridge spanning the BBC's first studio at Alexandra Palace which was once referred to as like a minstrels' gallery. Video of features of Alexandra Palace Master control is the technical hub of a broadcast operation common among most over-the-air television stations and television networks. Master control is distinct from a PCR in television studios where the activities such as switching from camera to camera are coordinated. A transmission control room (TCR) is usually smaller in size and is a scaled-down version of centralcasting. Production control room facilities Facilities in a production control room include: * A video monitor wall, with monitor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SKY Sport24 PCR
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere, concentric to the Earth, on which the Sun, Moon, planets, and stars appear to be drifting. The celestial sphere is conventionally divided into designated areas called constellations. Usually, the term ''sky'' informally refers to a perspective from the Earth's surface; however, the meaning and usage can vary. An observer on the surface of the Earth can see a small part of the sky, which resembles a dome (sometimes called the ''sky bowl'') appearing flatter during the day than at night. In some cases, such as in discussing the weather, the sky refers to only the lower, denser layers of the atmosphere. The daytime sky appears blue because air molecules scatter shor ...

Professional Audio
Professional audio, abbreviated as pro audio, refers to both an activity and a category of high quality, studio-grade audio equipment. Typically it encompasses sound recording, sound reinforcement system setup and audio mixing, and studio music production by trained sound engineers, audio engineers, record producers, and audio technicians who work in live event support and recording using mixing consoles, recording equipment and sound reinforcement systems. Professional audio is differentiated from consumer- or home-oriented audio, which are typically geared toward listening in a non-commercial environment. Professional audio can include, but is not limited to broadcast radio, audio mastering in a recording studio, television studio, and sound reinforcement such as a live concert, DJ performances, audio sampling, public address system set up, sound reinforcement in movie theatres, and design and setup of piped music in hotels and restaurants. Professional audio equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Control Unit
The camera control unit (CCU) is typically part of a live television broadcast chain. It is responsible for powering the professional video camera, handling signals sent over the camera cable to and from the camera, and can be used to control various camera parameters remotely. History Before cameras became self-contained units, broadcast cameras required vast racks of control units just to generate a usable picture. In outside broadcast production, these racks took up an entire section of the OB truck and were operated by a small team of skilled engineers. These vision engineers had two roles. Firstly, they set up the CCUs at the start of a production and ensured that the picture created was of broadcast quality. This process included a lengthy alignment process in which the vision engineer would work with the camera operator, to adjust the settings on both the actual camera and the CCU in tandem. During production, it was the vision engineers job to operate the CCUs and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vectorscope
A vectorscope is a special type of oscilloscope used in both audio and video applications. Whereas an oscilloscope or waveform monitor normally displays a plot of signal vs. time, a vectorscope displays an X-Y plot of two signals, which can reveal details about the relationship between these two signals. Vectorscopes are highly similar in operation to oscilloscopes operated in X-Y mode; however those used in video applications have specialized graticules, and accept standard television or video signals as input ( demodulating and demultiplexing the two components to be analyzed internally). Applications Video In video applications, a vectorscope supplements a waveform monitor for the purpose of measuring and testing television signals, regardless of format (NTSC, PAL, SECAM or any number of digital television standards). While a waveform monitor allows a broadcast technician to measure the overall characteristics of a video signal, a vectorscope is used to visualize chr ...

Waveform Monitor
A waveform monitor is a special type of oscilloscope used in television production applications. It is typically used to measure and display the level, or voltage, of a video signal with respect to time. The level of a video signal usually corresponds to the brightness, or luminance, of the part of the image being drawn onto a regular video screen at the same point in time. A waveform monitor can be used to display the overall brightness of a television picture, or it can zoom in to show one or two individual lines of the video signal. It can also be used to visualize and observe special signals in the vertical blanking interval of a video signal, as well as the colorburst between each line of video. Waveform monitors are used for the following purposes: * To assist with the calibration of professional video cameras, and to "line up" multiple-camera setups being used at the same location in order to ensure that the same scene shot under the same conditions will produce the sam ...
