Functional Description
Video Input Formats
The TW2864 has build-in automatic standard discrimination circuitry. The circuit uses burst-phase, burst-frequency
and frame rate to identify NTSC, PAL or SECAM color signals. The standards that can be identified are NTSC (M), NTSC
(4.43), PAL (B, D, G, H, I), PAL (M), PAL (N), PAL (60) and SECAM (M). Each standard can be included or excluded in
the standard recognition process by software control. The exceptions are the base standard NTSC and PAL, which are
always enabled. The identified standard is indicated by the Standard Selection (SDT) register. Automatic standard
detection can be overridden by software controlled standard selection.
TW2864 supports all common video formats as shown in Table 1.
