PT9 is a broadcast quality video encoder IP Core with cross-colour reduction.
When using a line comb decoder (the far majority of NTSC/PAL video decoders use a line comb architrecture) it is inevitable that either some artifacts will be produced or resolution will be lost if masking those artifacts. The PT9 NTSC and PAL encoder offers the same broadcast quality encoding as our PT8 encoder, but also offers a proprietary cross-colour reduction mode that eliminates those components of the composite video signal that will cause these artifacts. The zone plate image (above) shows the cross-colour produced by a conventional line comb decoder (left). On the right is the same decoder when used with the PT9 video encoder in cross-colour reduction mode. Additionally, the PT9 has a pre-emphasis filter which can compensate for high frequency loss when driving SD video over long lengths of cable.
