videójel

Videójel is a Hungarian term that translates to "video signal" in English. It refers to the electronic signals that carry visual information, allowing for the display of images and moving pictures on screens. These signals are fundamental to the operation of all video-related technologies, from traditional broadcast television to modern digital displays and streaming services.

Video signals can be transmitted in various forms, both analog and digital. Analog video signals, like those used in older television systems such as NTSC, PAL, and SECAM, represent image information as continuous waves of voltage. Digital video signals, on the other hand, encode visual data as discrete numerical values, which are then transmitted as binary code. This digital approach has become dominant due to its superior quality, resilience to noise, and ease of processing and storage.

The process of generating a video signal involves capturing light using a camera sensor, which converts it into electrical or digital data. This data is then processed and formatted into a signal that can be transmitted. At the receiving end, a display device, such as a television or computer monitor, interprets the video signal and reconstructs the image on its screen. Different types of video signals exist, varying in resolution, frame rate, color depth, and compression methods, all contributing to the final quality and characteristics of the displayed video.
