The TB1311AFG does not support weak signals, ghost signals or other nonstandard signals. Therefore, these signals
should be dealt with through the use of another device capable of handling these signals, such as a color-decoder. In
these cases, the signal switcher and the video circuits of the TB1311AFG can be used. In some cases, “no-input
detection” can be also used for these signals.
The TB1311AFG cannot distinguish between component and RGB video. The different kinds of input signal should be
separated through the use of different signal-specific input pins; for example, specific-purpose pins for RGB video input
only or component video input only.
(2) For standard component video (SMPTE STANDARD) and standard RGB video (VESA STANDARD)
