BD7620KS2 Application Field and Working Principle

Linear video processing is an important part of digital video processing, and a key factor for its success is the use of efficient linear video processing algorithms and hardware. The BD7620KS2 is a monolithic integrated circuit that provides a highly efficient linear architecture for video processing. This device is ideal for applications such as television broadcast and professional video equipment.

Overview of BD7620KS2

The BD7620KS2 uses a unique linear architecture to accomplish video processing tasks with only two analog blocks. The first block is composed of two differential amplifiers and several non-inverting stages. These amplifiers provide the analog signal conditioning required for the language processing algorithms. The second block is composed of the logic settings that control the timing of the language operations.The BD7620KS2 has a total of eight linear video processing channels. It can be configured for one of three video processing settings: crossbar, matrix or summation. When configured in crossbar mode, the video is processed as a set of independent signals, with each signal being processed independently from the others. In matrix mode, the video signals are processed as a single image, with the output from one channel being used to determine the input of the next channel. In summation mode, the video signals are processed in the same manner as in matrix mode, but with one signal driving all the channels in parallel.

Applications of BD7620KS2

The BD7620KS2 is ideal for applications such as professional video equipment, broadcasting and cable TV systems. It is well-suited to television broadcast and professional video equipment due to its low power consumption, noise immunity and excellent rejection of signal interference. The device also offers low-pass roll off and wide dynamic range. Additionally, the BD7620KS2 is capable of processing stereo audio signals, offering a higher signal-to-noise ratio than traditional linear processing.In the professional video equipment domain, the BD7620KS2 is well-suited for digital signal processing in video encoders, digital video cassettes, and other video-processing systems. It is also well-suited for real-time video compression and digital video compression applications, offering a hardware solution for motion estimation and motion vector prediction.

Working Principle of BD7620KS2

The BD7620KS2 is based on an optimized linear architecture that utilizes the principles of time-division multiplexing and parallel processing. The device operates in a two-stage configuration, with each stage consisting of two or more analog functions. The first stage consists of analog signal conditioning, while the second stage consists of the logic settings that control the timing of the language operations.The BD7620KS2 uses the same logic-based algorithms as the popular Nippon DENKI IDEAS language processing chip. These algorithms are used to manipulate data in the form of language fields and pixels. When a language field is selected, it is processed by the chip\'s logic settings. This allows for a wide variety of language operations, including but not limited to addition, subtraction, multiplication, division, and shifting operations.

Conclusion

The BD7620KS2 is an ideal device for linear video processing applications, providing a high level of efficiency, low power consumption and excellent resistance to noise interference. Its unique linear architecture enables a wide variety of language operations, making it suitable for use in a wide range of digital video processing applications. The device is well suited for applications such as professional video equipment, broadcasting and cable TV systems.
