field-sequential color TV system
Noun: An early form of color television technology. In this system, the complete television picture (a frame) is created by displaying three successive fields, each scanned in a different primary color (red, green, and blue). The viewer's perception blends these rapidly displayed monochrome fields into a single full-color image.
This term is a technical, historical noun used to describe a specific obsolete television technology. It is typically used in technical discussions, historical reviews of broadcasting, or academic contexts concerning the evolution of color television.
- The field-sequential color TV system was an important, though ultimately non-commercial, step in the development of modern color broadcasting.
- Early experimental broadcasts used a field-sequential color TV system, which required a special spinning color wheel in front of the television screen.
- The main drawback of the field-sequential color TV system was its incompatibility with existing black-and-white television sets.
The system is often discussed in contrast to the simultaneous color system (like NTSC, PAL, or SECAM), which transmits color information simultaneously and is compatible with monochrome receivers. * While the field-sequential system was mechanically complex, it demonstrated the fundamental principle of additive color mixing for television.
- Field-Sequential System: A common shortened form.
- CBS Color System: Refers specifically to the field-sequential system developed and championed by the Columbia Broadcasting System (CBS) in the 1940s and 50s.
- Color Wheel TV: An informal descriptive term referencing the mechanical color wheel used in some receivers for this system.
- Sequential Color Television
- (Historical/Technical context) CBS Color Television System
