NJM2233BD is a integrated video processing analog circuit created by New Japan Radio, and it has a variety of application fields and working principles. This integrated video processing analog circuit is classified as part of the linear-video processing field and it is composed of various components with varying working principles.

This circuit, NJM2233BD, comes with integrated circuits such as the NJM2233BD-V and NJM2233PC. Both of these substrates contain two channels, with each channel having five independent analog channels for processing video. By connecting these analog channels to inputs in the form of composite video, Video Sync, or other formats, one can make use of the processing capabilities of this integrated circuit.

First and foremost, the NJM2233BD-V is the processing substrate of the NJM2233BD-V. This substrate is designed to handle the input of composite video, Video Sync and other formats. Its main function is to convert these signals into analog form, perform video timing control and perform the subsequent processing tasks. The circuit can be adjusted to use up to four input channels and up to twelve output signals. Once these signals have been acquired by the circuit, they can be combined and sent to an encoder where they will be outputted in digital format.

The components of the NJM2233BD-V are the Video Signal Input Unit, Video Processing Unit, Memory Interface and Video Output Unit. The Video Signal Input Unit is responsible for receiving input signals from the external sources. It is comprised of various analog circuits such as high-voltage amplifiers and analog multiplexers. The Video Processing Unit is responsible for controlling the input signals and performing the video processing tasks. It uses an array of analog circuits such as comparators, video timing controllers and video switch controllers. Lastly, the Memory Interface is responsible for storing the processed output of the video processor, while the Video Output Unit is responsible for encoding the processed output and outputting it as digital signals.

The NJM2233PC, on the other hand, is the processing substrate of the NJM2233PC. This substrate is designed to handle the input of different resolutions, such as HD, SD and 4K, as well as various aspect ratios such as 16:9 or 21:9. It has the same analog circuits as the NJM2233BD-V, with the exception of the Memory Interface. Instead, the NJM2233PC has its own integrated processor, named the Euler Processor, that is responsible for controlling the processing tasks of the circuit. The Euler Processor is capable of performing advanced functions such as image scaling and image alignment.

The main use of the NJM2233BD and its components is to provide the video processing necessary for video projectors, displays, video walls, and video surveillance systems. By having the ability to receive and process different sources of video, as well as having the ability to output digital signals in different resolutions and aspect ratios, this integrated processing circuit offers greater versatility and flexibility to video professionals. The capability of being able to scale images and align them, without having to go through manual processes, is invaluable to video professionals, as it offers them greater precision in the outputted products. The working principles of the various circuits of the NJM2233BD, as described above, makes it a highly valuable integrated video processing circuit.
