The specific TV broadcast equipment can vary depending on the size, budget, needs and also technological preferences of different broadcast centers. Here’s a list and the related overviews of some of the key studio equipment needed for broadcasting on TV:

Video Production Switchers: In the context of television broadcasting, Video Production Switchers are a critical piece of studio equipment used to manage and integrate multiple video sources during a live production.

Clean Switch: a “clean switch” refers to a seamless, imperceptible and noiseless transition between video and audio sources during a live production.

Embedders: Sdi Audio Embedder is used to integrate audio signals into a video signal, creating a single, combined audio-video stream.

The primary function of an embedder in broadcast environments is to take multiple audio sources (such as microphones, sound effects, music, etc.) and “embed” them directly into the corresponding video signal. This allows the audio and video components to be transmitted, distributed, and processed as a cohesive, synchronized unit throughout the broadcast workflow.

De-Embedder: Sdi Audio De-embedder modules are used to extract the audio signals from a combined audio-video stream, effectively separating the audio and video components.

The primary purpose of a de-embedder in broadcast production environments is to take a single, combined audio-video signal (typically an SDI) and split it back into its individual audio and video components. This allows the audio and video to be processed, routed, or monitored independently as needed.

Digital Video Distributor (Video Equalizer): a digital video distributor is a module used to duplicate the input signals as are and distribute them within a broadcast infrastructure.

Multiviewer: Sdi Multiviewer modules are specific image processing tools that allow for the simultaneous monitoring of multiple video signals on PIP displays.

The primary function of a Multiviewer is to provide a comprehensive visual overview of various video sources and related information, enabling broadcast professionals to efficiently monitor and manage the production and transmission processes.

Up/Down/Cross Converters: up down cross converter is often used to convert video signals between different video formats, resolutions, or standards.

The primary purpose of cross-converters in a broadcast production center is to facilitate seamless integration and compatibility between various video equipment and systems that may have different video signal requirements.

Intercom Systems: An IP based intercom system is a crucial communication tool that enables real-time, interactive audio communication between various personnel involved in the production and technical operations of a broadcast.

Players and recorders, playout, CG (Character Generator), SPG (Sync Pulse Generator), Waveform Monitor, Camera and Lens and so on are all studio equipment that is used in television broadcasting.

Equipment for Broadcasting on TV

Now let’s dive deeper into this television studio equipment :  

• Broadcast cameras 

Broadcast-quality video cameras are the core of any TV production setup. They come in different form factors like camcorders, studio cameras, and PTZ (pan-tilt-zoom) cameras.

Key features of this equipment include large image sensors, interchangeable lenses, professional audio inputs, and robust build quality to withstand rigorous use.

• Signal Routing and Video Switching

Video switchers/mixers are the heart of a live production, allowing the director to seamlessly transition between camera feeds, graphics, and other sources.

Other features include picture-in-picture, Chroma keying, and digital effects for enhanced production values. Graphics systems integrate motion graphics, titles, and other visual elements into the program.

• Recording and Playback:

Video recorders capture the program output for later broadcast or archiving. These range from professional-grade video servers to file-based recording systems.

Clip playback servers allow producers to quickly access and integrate pre-recorded content into the live show.

• Signal Monitoring and Quality Control:

Multiple Video Screens fed by multi-image processing modules allow the director, technical director, and other crew to view the program output and individual sources.

Intercom systems facilitate communication between the production control room and field personnel for coordinating the production.

Automation systems and machine control provide centralized command of the various equipment in the broadcast facility.

• Transmission:

Video encoders compress the raw program feed into a broadcast-ready format, optimizing the video and audio quality for transmission.

Modulators convert the encoded signals into a format suitable for distribution over terrestrial, cable, or satellite channels.

Transmitters then broadcast the signal to the intended audience, whether over-the-air, through a cable system, or via satellite uplink.
