Using 1Seg
• 1Seg is a service provided by television entrepreneurs
(broadcasting stations). You are not charged a communication
fee for receiving video and audio. For about fee charged by
NHK, contact NHK.
• There are two types of information displayed in the data
broadcast area: "data broadcast" and "data broadcasting site".
"Data broadcast" is transmitted via broadcasting waves along
with video and audio. To view a "data broadcasting site"
prepared by a TV broadcaster (station), you need to access the
site from information contained in data broadcast.
Packet communication fee is charged for viewing "data
broadcasting sites". Using some sites may also incur
information fees.
■
Broadcasting waves
1Seg, one of the broadcasting services, is transmitted using a
different radio wave (broadcasting wave) from that used for
FOMA services. Therefore, 1Seg cannot be received in places
where broadcasting wave cannot reach or during hours in
which 1Seg broadcasting service is suspended, regardless of
whether you are in the FOMA service area.
Furthermore, even in the terrestrial digital TV broadcasting
service area, reception may be poor or impossible in such places
as listed below:
• Places away from radio towers transmitting broadcasting
waves
• Places where radio waves are interrupted by land features or
buildings such as in mountains and beside a tall building
