👉 VHS (Video Home System) math involves the analog signal processing and data encoding techniques used to store and transmit video and audio information on VHS tapes. The process begins with the analog capture of video and audio signals, which are then digitized using a process called analog-to-digital conversion (ADC). This conversion involves sampling the continuous analog signals at regular intervals and quantizing them into discrete digital values. The VHS tape itself is a physical medium that stores these digital data sequences in a spiral track, where each cell represents a 16-bit or 24-bit pixel value. The math here includes understanding the tape's physical properties, such as its length, track pitch, and density, which affect how data is stored and retrieved. Additionally, VHS systems use error correction codes to ensure data integrity over the tape's lifespan, involving complex algorithms to detect and correct errors introduced by noise or physical degradation.
