Setting your PSP to Japanese region you are able to use a 1seg PSP TV tuner, here are pics
but I'm wondering how the 1seg tuner works? does it use DVB? cos i would really want one, but in Norway we don't broadcast analog ground signal, only digital ground signal, cable and satellite. (half way lie, but the analog signal will be shut down this year anyway). So does this 1seg tuner get analog signal? or digital, I'm not sure what TV system they use in japan. In Norway its digital MPEG4 picture with HD (no HD channels on the ground signal yet, only satellite) and SD technology.
anyone know if i will be able to use the 1seg if i import it?
