Sorry Roy, I don't think that we will be seeing anything anytime soon...
Mobile TV
Mobile reception of digital stations using ATSC has (until now) been difficult to impossible, especially when moving at vehicular speeds. To overcome this, there are several proposed systems that report improved mobile reception:
Samsung/
Rohde & Schwarz's
A-VSB,
Harris/
LG's
MPH, and a recent proposal from
Thomson/
Micronas; all of these systems are expected to be submitted as candidates for a new ATSC standard,
ATSC-M/H. This is in addition to other proprietary standards like
MediaFLO, and worldwide open standards such as
DVB-H and
T-DMB. Like DVB-H and ISDB
1seg, the proposed ATSC mobile standards are
backward-compatible with existing tuners, despite being added to the standard well after the original standard was in wide use.
Mobile reception of some stations will still be more difficult, because 18 UHF channels in the U.S. have been removed from TV service, forcing some broadcasters to stay on VHF. This band requires larger antennas for reception, and is more prone to
electromagnetic interference from
engines and rapidly-changing
multipath conditions.
