I found japanese old phone have a receiver for ISDB-T/1seg (oneseg or in japan is “ワンセグ, wansegu”). then i explain him about this..

then him send video capituring tv digital can him received, i realized on video have distortion like digital receiver.

then i explain what i found and i know about ISDB-T (digital television Japan)..
