A video is processed by its processor, which is an integrated chip embedded in the system to improve and manipulate video signals before they are sent to production.
Signal processing techniques used in video processors include statistical analysis, visual filters, and information extraction or manipulation. Trimming, image resizing, brightness and contrast adjustments, and fade in and fade out are just a few examples of basic video processor procedures.
How Does a Video Processor Work?
Video processors make use of hardware, software, or a combination of these two to edit the images and sound stored in video data. A wide range of techniques and algorithms in the processing software is embedded so that the user can operate editing and manipulating functions with the help of these filters. Signal processing is used in video processors to clear up video streams by optimizing visual signals. It serves a number of purposes, such as:
- Aspect ratio control - A technique used to allow the video image to remain embedded in the right sizes and shapes and remain preserved always.
- Upconversion - This is the technique for transforming standard definition signals to high-definition video quality.
- Lip sync - This function allows audio-visual streams of a video to be completely coordinated.
- Edge enhancement - A video processor makes sure the edges between a subject and its background signal and contrasts are being enhanced to produce a high-definition video picture.
Why is Video Processing Important?
Creating high-quality visible-light videos for human consumption is the primary use of digital video processors. Numerous methods that are derived from the fundamentals of digital image processing are included in the field of digital video processors.
Versatile Uses of Video Processing
A video processor comes in a wide range of applications embedded, including:
- Blu Ray players
- DVD Players
- Televisions
- AV Receivers
