Video signal bandwidth versus resolution
TA0310
The third type of signal format is composite video (CVBS). The aim of this signal format is to combine all
the video components into only one signal. CVBS is the sum of Y and C. This signal format is the lowest
quality format.

Standard Definition (SD):
Video signal used in standard interlaced video with a TV screen of 720*480 pixels (type: 480I). The
bandwidth is up to 6MHz.
