    NTSC format and a 625-line format will load the PAL format. 3.6 Decoding Filter The ASD-231i provides the 5 types of decoding filters which are listed in Table 3.1. The selection of a decoding filter will depend highly on the nature of the input composite signal. For example, choosing between A-3D and A-2D will depend highly on the content of your source.
