The problem with Bert is that his head is hopelessly stuck in the
sands of time...
He is focused on the past, not the future.
I heard many rumors at NAB, so of which, if true will send a few
ripples through the ATSC-centric world. Bert has long held that it is
important to have long term certainty about the target receiver for
any broadcast system. In this he has been supported by the ATSC and
broadcast community. Bottom line:
"We cannot have ANY receiver go black for any ATSC broadcast mode."
Obviously the MHP enhancements are an exception to this mantra. But
what would happen if Table 3 were to be modified, and some aspects
of the main ATSC standard were to be updated to reflect current
realities?
Imagine the public reaction when the millions of consumers, who have
been forced to buy an ATSC receiver in their big new HD capable
display, learn that they will need a new STB to receive the enhanced
ATSC broadcasts...
Bert still focuses on the original DVB-T standard when comparing the
efficiency of the NEW ATSC MPH enhancements.
But the DVB is moving on. DVB-T2 may be deployed in the U.K. by the
time any meaningful MPH deployment takes place here in the U.S..
And there there is MIMO and the possibility of allowing DVB-T2 to
deliver upwards of 40 Mbps in an 8 MHz channel.
So much for Bert's spectral efficiency arguments.
But even this pales when one compares what the U.S. broadcasters
consider to be their path to a mobile future, with the announced
intentions of Verizon and AT&T to deploy 4G LTE based networks in
their newly acquired 700 MHz spectrum. Broadcasters will be limping
along with 2-3 ruggedized streams that deliver 250 - 500 Kbps
payloads, while cellular customers will be able to download content
in bursts at 100 Mbps.
GAME OVER.
