Jelaskan Mobile TV dari Standar ATSC dalam bahasa sunda

Because the FCC forced broadcasters to use 8VSB modulation instéad of COFDM, mobile reception of digital stations has (up till now) been difficult to impossible, especially when moving at vehicle speeds.  To overcome this, there are now at léast three standards which claim to improve mobile reception: Samsung's A-VSB, Harris and LG's MPH, and now the ATSC's own ATSC-M/H.  This is in addition to other proprietary standards like MediaFLO, and worldwide open standards like DVB-H and DMB-T.  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 the FCC sold-off the rights to 18 of the UHF channels, forcing several 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, aréas where ATSC's 8VSB is inferior to the COFDM of other standards.
