AHDTV stands for Analog High Definition Television. The tag is defined in the SD and HD x264 TV rule sets:

ª   - HD video taken from the decoded HD output of a set-top box (e.g.        ª
ª     component, DVI, HDMI) must be tagged in dirname as AHDTV. Decoded       ª
ª     output of PDTV or DSR sources is banned. Releases taken from a natively ª
ª     recorded transport stream shall be tagged as HDTV, PDTV, or DSR.        ª
ª     - AHDTV captures must be done at the native format of the channel, e.g. ª
ª       720p or 1080i.                                                        ª

“The “A” in the “AHDTV” tag is for Analogue High Definition TeleVision, or in other words component cables. I see the intent to note it is not from the transport stream but that doesn’t make HDMI analogue you idiots.” [Source]
