Explain 10 bit video processing?

Question

I see this term sometimes. What does it mean in theory and in practice?

Answer 1

Standard video signals are 8-bit (0-255 for computers, 16-235 for video). You can't add bits that weren't originally encoded, so that 8-bit number firmly determines the gray-scale resolution. However, signal processing always has the potential of degrading signals, and that degradation can be reduced if the 8-bit signal is converted to 10-bits and the processing done with more precise 10-bit circuits. After processing is complete, the signal may be converted back to 8-bits. The result will be less deterioration than if the processing were done 8-bit throughout.
