TIMEBASE Meaning and
Definition
-
Timebase is a fundamental concept utilized in several fields to refer to a standardized reference point or frequency against which other events or measurements are synchronized or measured. It provides a consistent frame of reference for various processes, ensuring accuracy and synchronization.
In the realm of electronics and technology, timebase refers to a circuit that generates a precise, stable, and regular signal used as a reference for synchronizing electronic systems or devices. This signal often takes the form of a regular waveform, such as a sine wave or a square wave, and serves as a timing base for other operations. Timebase circuits commonly function as oscillators, producing a consistent frequency that enables precise timing in devices such as computers, telecommunication systems, and digital circuits.
In the context of video and television production, timebase refers to the synchronization and alignment of multiple video signals to create a coherent display. This entails ensuring that each frame is displayed at the correct time, thus preventing issues like frame skipping or display lag. Timebase correction techniques, such as frame synchronizers and timebase correctors, are employed to maintain this synchronization by aligning video signals with a stable reference.
Overall, timebase acts as a fixed reference point, allowing various systems, circuits, or signals to function in unison and maintain accuracy, timing, and synchronization.
Etymology of TIMEBASE
The word "timebase" is a combination of two separate words: "time" and "base".
"Time" originates from the Old English word "tīma", which means "hour, season, or period". It can be traced back to the Proto-Germanic word "*tīmô", which was related to measuring and referring to a specific portion or division of a day or year.
"Base" comes from the Old French word "bas", which means "low" or "lowly". This word is derived from the Late Latin word "bassus", used to describe something sitting close to the ground or foundation.
When combined, "timebase" refers to a fundamental or foundational unit or measure related to time. It is often used in technical contexts to refer to a system or component that controls or sets the timing for other processes or events.
