NERA integrated the first
commercial Mobile DTV system in the World
The Digital Mobile Network and system project has been commissioned in 2001.
Here's some information, which should be useful....
TV
Mobile digital network
- Single-frequency network (Channel 37)
- Main transmitter plus nine fill-in sites to give 99% coverage
- Two video streams
- 2k carriers, 16QAM modulation for 'rugged' reception on-the-move
- 1/2 forward error correction rate, 1/4 guard interval
- Audio also carried on conventional FM for individual
reception on portables
- Multiple LCD screens on 1500 buses
- On-air February 2001
- Program services operated by MediaCorp (MCS)
NERA was contracted to plan, design and build the multiplexing and
transmission system for Singapore's mobile digital TV service follows
successful trials in 2001. Initially the most robust but least efficient
form of COFDM modulation was used (QPSK). This produced extremely reliable
reception, even to the extent
that passengers were unable to appreciate the 'difficulty' of providing
off-air TV pictures on-the-move!
For the permanent service, higher-order modulation (16-QAM) will be used to
increase the capacity of the system while still maintaining robust
reception. For fixed-aerial reception (as in the UK), 64-QAM modulation is
more usual, allowing even more programme streams but with a consequent loss
of robustness.
As is often the
case, audio provides many challenges in the TV environment. On the buses,
audio was distributed through small speakers situated around the bus
interior. With the inevitable range of individual preferences, audio level
could be a real problem. The audio channels were therefore also
distributed via conventional FM transmitters allowing independent reception
through existing portables.
To
install a bus takes one team of 6-8 men one night to complete. To equip 1500
buses, clearly a large and well-planned multi-team installation schedule was
involved, and NERA Telecommunications Ltd has successfully managed that!
