You will use video processors when you work with DVD players, televisions, A/V receivers, Blu Ray players, and other video devices. They use signal processing to optimise video signals for a clear video stream.
What do you need video processors for?
Video processors have a variety of functions, including:
- Aspect ratio control – this ensures that the video image stays within the correct dimensions and doesnt become distorted.
- Upconversion – this is the process of converting Standard Definition (SD) signals to HD quality.
- Lip sync – this feature ensures that audio-visual parts of a video are perfectly synchronised.
- Edge enhancement – a video processor will find the edges between a subject and its background and increase the contrast to create a clearer video image.
You will commonly use video processors with video buffers, which process video information ahead of time to create a seamless video experience.
Types of video processors
Video processors are either in chip or stand-alone form. You will fit a video processing chip inside a device, whereas a stand-alone video processor will sit between a source device, such as a DVD player, and the screen.
