During digital playback or broadcast ____ means COLOR info must be synchronized with BRIGHTNESS info for each pixel of each frame.

• A. Luma
• B. Chrominance
• C. Sync
• D. Gamma

Answer: (C)

The idea being tested is synchronization of timing between color and brightness data in a video stream. Brightness (luma) defines how light or dark a pixel should be, while color (chrominance) provides hue and saturation. For every pixel in every frame, the color information must line up with the corresponding brightness value at the exact same moment in the signal. That precise timing control is what keeps the color data connected to the correct brightness across the entire image sequence, which is described by the concept of synchronization. Gamma relates to how brightness values are mapped for display and isn’t about timing, while luma and chrominance are the raw data components, not the timing mechanism.
