Picture format:
The number of scanning lines, followed by the number of interlaced fields or
progressive frames per second, followed by the designation “i” for interlaced scanning or “p”
for progressive scanning.
Number of pixels:
Horizontal x vertical.
Aspect ratio:
Ratio of picture width to picture height.
Luminance sampling frequency:
The number of digital video samples per second for the black-and-
white (luminance or “Y”) channel , measured in megahertz (millions of cycles per second).
Sampling format:
Refers to the structure of the three video channels: Y (luminance), Cb (blue color
difference, Y-B), and Cr (red color difference, Y-R).
Bits per sample:
The number of bits devoted to each digital video sample.
Bitrate:
The recorded data rates for audio and video, measured in bits per second. “kbps” stands for
kilobits per second. “Mbps” stands for megabits per second.
For maximum flexibility, the AVCHD format supports both 1080- and
720-line High Definition as well as Standard Definition video.
