Ofcom u-turn on digital dividend

Consequences for DTT and the music and concert industry ...

http://news.bbc.co.uk/1/hi/technology/7870459.stm

Personally, while I concede the need for European-wide standards, my
overriding concern is that the money grubbing b*st*rds stop flogging
off TV bandwidth to other purposes and instead use it to give us
better quality DTT with no or at least as little as possible
compression!

Well the good news is the DTT will be reallocated away from 800 MHz to
some other frequency...so no harm done!

No compression is obviously never going to happen - 270 Mbps per TV
channel is abotu 135 times higher than the bit rate used by some TV
channels today!

IMO, it is the right *long-term* decision to use the TV bandwidth for
mobile broadband. Mobile broadband has grown at a phenomenal rate over
the last year or two, and 800 MHz is about the best frequency band to
use for mobile broadband - terrestrial TV doesn't need to use
frequencies that are perfect for mobile applications.

BT should enable multicast on its 21CN network, and they're going to
put Ethernet sockets on new Freeview and Freesat set-top boxes to
allow people to watch iPlayer streams on their TV sets. If they
included code to receive multicast at the same time we could get far
better quailty via the Internet than we could ever hope for via DTT.

The adoption of DAB was the most incompetent technical

The proposal is basically a channel-shuffling one.

Post-DSO, DTT would use channels 39 and 40 instead of 61 and 62. Arqiva
have come up with a frequency plan that shunts assignments around so
that all six multiplexes from a particular site will be in same aerial
groups as the existing DSO plan.

Because this wheeze has come so late in the day, many of the channel
moves will have to take place after DSO. (Ofcom's analysis appears to
have overlooked the implication of this for communal aerial systems with
channel filters.)

PMSE would get channel 38 instead of 69.

So will Winter Hill viewers require a new antenna in November 2009,
or will their group C/D antenna be adequate for PSB-1 multiplex way
down on channel 39 or 40?

It doesn't work like that. The plan avoids moving channels that far.
Typically, channels 61 and 62 will move down to ch 50-ish to keep them
in group, and some planned assignments at around ch 50 will move down to
39/40 (i.e. within group B) to make room for them.

They won't have overlooked it. They will have said, "The cost will be borne
by landlords and residents, so it doesn't matter to us."

Forgive my ignorance. Am I right in assuming that has a positive
affect on the continued use of radio mics or in-ear monitoring
systems?

Yes, for those of us that have grouped aerials it looks we might need to
upgrade post DSO. Thanks Ofcom ... not.

Except that the companies have not invested in the gear to let everyone have
wide bandwidth internet at peak times of course.
