The Genesis chip's tends to go into video mode more often (when there are hiccups in the 3-2 cadence) and stay there longer. Because of the DCDi™ processing, it's not always obvious when the Genesis goes into video mode
แต่คิดอีกมุมนึง .... ถ้าคุณภาพของ film mode drop ลงจนเครื่องเล่นต้องมา process แบบ video mode แล้ว สงสัยว่า คุณภาพตอนนั้นถึงใช้ dcdi ช่วยก้อคงไม่น่าพอใจมากนักมั๊งครับ
DCDi is a video mode algorithm that stands for Directional Correlation Deinterlacing. It was designed for video based material fast-paced sporting events. Its purpose is to eliminate jagged edges (jaggies) along diagonal lines caused by interpolation. If you remember, you are not simply weaving together two fields of video that match, you have to create new information through the art of interpolation which is really a fancy way to say you are guessing. DCDi monitors edge transitions and fills in the gaps. The technology was introduced a few years back in the digital format translator, a $50,000 system that broadcasters CBS use to upconvert NTSC to HD. It was/is used to upconvert standard definition material (480i, what we have on conventional TV) to enhanced definition quality (480p). You may already being enjoying DCDi today on your digital TV. ..........
