FBE (Frame-based equipment)
Frame-based equipment (FBE) refers to a type of electronic equipment used for signal processing and routing in professional audio, video, and broadcast systems. FBEs are typically modular in design, consisting of a series of interconnected frames or racks that contain various cards or modules with different functions. These frames can be customized and expanded as needed, allowing for a high degree of flexibility in configuring and reconfiguring the system.
FBEs are widely used in the broadcast industry for tasks such as video and audio routing, signal distribution, conversion, and processing. They are also commonly used in post-production and live sound applications. In this article, we will explore the basic components of FBEs, their functions, and some common applications.
Basic Components of FBEs
The basic components of an FBE include a frame or chassis, modules, backplanes, and power supplies. The frame or chassis is typically a metal rack that holds the various modules or cards. The number of slots in the frame can vary from a few to hundreds depending on the specific model and application.
Modules or cards are the functional units of an FBE. Each module is designed to perform a specific task such as audio processing, video processing, or signal routing. There are several types of modules available, each with different functions and specifications. Some common types of modules include audio and video crosspoints, signal converters, time base correctors, video and audio processors, and sync generators.
The backplane is the internal wiring system that connects the modules to each other and to the power supply. The backplane ensures that the modules are interconnected correctly and that the signals are routed to the appropriate modules. The backplane can also provide power to the modules, eliminating the need for individual power supplies for each module.
Power supplies are an essential component of FBEs. They provide the necessary voltage and current to operate the modules and ensure that the system operates reliably. Depending on the specific model, FBEs may have one or more power supplies. Some high-end models may even have redundant power supplies for added reliability.
Functions of FBEs
FBEs can perform a variety of functions depending on the modules installed in the system. Some of the most common functions of FBEs include signal routing, conversion, and processing.
Signal Routing: One of the primary functions of FBEs is to route audio and video signals from one source to another. This is accomplished using crosspoint modules that allow the user to select which inputs are connected to which outputs. For example, in a broadcast studio, a crosspoint module may be used to route audio from a microphone to a mixer, and then to a video switcher for final output.
Signal Conversion: FBEs can also be used to convert signals from one format to another. For example, a signal converter module can convert an analog audio signal to a digital signal or vice versa. This is useful when working with equipment that only supports a certain type of signal or when integrating new equipment into an existing system.
Signal Processing: FBEs can also be used to process audio and video signals in various ways. For example, audio processors can be used to adjust the level, tone, and other characteristics of audio signals. Video processors can be used to adjust the color, contrast, and other parameters of video signals. Time base correctors can be used to correct timing errors in video signals, ensuring that the image is stable and free of distortion.
Applications of FBEs
FBEs are widely used in the broadcast and post-production industries for a variety of applications. Some common applications include:
Broadcast Production: FBEs are used in broadcast production to route audio and video signals between equipment such as cameras, switchers, and audio mixers. They can also be used to process signals to ensure that they meet broadcast standards, such as adjusting audio levels or correcting timing errors in video signals.
Post-Production: In post-production, FBEs are used to process and edit audio and video signals. They can be used to adjust color, add effects, and correct timing errors. FBEs can also be used to convert signals from one format to another, allowing editors to work with different types of footage.
Live Sound: FBEs are also used in live sound applications, such as concerts or events. They can be used to route audio signals between equipment such as microphones, mixers, and speakers. FBEs can also be used to process audio signals, such as adjusting the tone or adding effects.
