The decoded pictures should be reordered according to the following rules: • If the current decoded picture is a B-picture, output the current decoded picture directly. • If the current decoded picture is I, G, S or P picture, output the previous decoded I, S or P picture if it existed; output the previous decoded G-picture if it existed and it should be output; no picture is outputted if it did not. 3 Scene Video Coding 47 • When all pictures have been decoded, if there are still decoded pictures except non-output G-picture in the buffer, output it.
0 via Wikimedia Commons historically proposed for black-and-white/color TV compatible transmission. Y is the existing luminance signal for black-and-white TV broadcasting, and UV signal are added for color information. YIQ is similar to YUV, and the Y component is same in the two color spaces. I and Q represent the chrominance information and can be thought of as a new coordinate system rotated from UV coordinate with 33◦ . YCbCr is also similar to YUV and YIQ, but it is usually used for digital video.
