View Full Version : My first impressions.. DTV and DVB300

Hey all,

I've been a lurker round here for a while, but having just bought into DTV,
I thought I would pop my head up and say gday.

Anyway, I live in an rental place that has no external aerial, and as such
poor analogue reception. The image has double images sometimes, almost
complete loss of signal other times etc... Basically, I decided that the
headaches I was getting from the double image was not worth it and I decided
to get an STB. Given that it was just for improved reception, I thought I
would get a cheapy unit now, and wait another couple of years before getting
a better unit with recorder etc... later (possibly even HDTV if it kicks
off). So, in post-chrissy sales, I saved about a third off normal pricing
(below RRP, but everyday prices).

I hooked the DVB-300 up to my 72cm 4:3 TV via SCART, and the sound by
optical to the amp, and switched it on. The auto-search for stations failed,
so I had to start it manually through the menu system. After about 5min, it
completed, and all the Canberra stations appeared. Despite my fear that my
signal would be too poor even for DTV, all stations come through really
clearly.

The remote for the DVB-300 is the first thing that I looked at, and have to
admit that TEAC did a pretty good job with this one.
The image quality is the niext issue. The image quality does not appear to
be as good as the Strong STB, though for a saving of over $100, I am not
complaining. The Teac seems to clip highlights, such that when watching the
cricket, the highlights are represented by almost solid white info,
obscuring any detail. The colours also seem a little oversaturated,
particularly the reds. Now this is appearing on a calibrated TV. I should
say that as a semi-serious photographer, I am a bit more sensitive to these
sort of things than most people. My gf only picked up the colour issues
after I pointed them out to her, and another friend didn't even notice it
then. To me the highlihgt problem is most noticable on WIN, but the
oversaturation is on all stations. I can "adjust" the TV, but then it throws
the correct calibration (set up for DVD and analogue TV) out the window.

As for sound, it is rather good. The MPEG stereo sound is pretty good for
all stations - and it is particularly good to finally have Ten Capital in
stereo. The AC3 that ABC puts out is even better on my system. There is a
little more dynamic range than the MPEG stream. All up, the sound wallops
analogue. Just a quick question... does anyone know if ABC ever puts DD5.1
over the AC3 on there SDTV broadcasts. Not expecting it, but it would be a
nice bonus if it does.

Other issues: I would have preferred the box to auto detect the aspect ratio
of the broadcasts (do aussie stations even put this info across). However, I
do like how when switching the aspect via the remote, the info is sent via
scart to the tele, that automatically switches in and out of its 16:9 mode.
I would also liek to be able to remove the "4:3 letterbox" mode from the
Aspect button switching. Finally, the switching between channells, is as
fast as my analogue TV does it, so I am not concerned (this was a concern to
me, after trying a friends "old" TEAC box about 12 months ago. This box is
much, much better)

Now as for my impressions of DTV. It is certainly taking a little getting
used to watching the cricket in widescreen, but it is enjoyable. I can see
myself using whenever possible. The image clarity is really good, and the
lower signal strength required is great. I am now no longer getting
headaches in front of the tele.

It is rather disappointing that the stations are not broadcasting EPG info.
Only ABC seems to have it on the stations, whilst SBS has its own station.
The networks should pull their fingers out.

I reckon my DV-B300 is pretty slow to change channels compared to any of my
analogue sources. It's at least a 2 second delay.

Wild Swans, a ballet performance was broadcast in AC3 5.1 a month or so ago.
I think apart from one other experimental broadcast a while ago, this was
the only time they broadcast 5.1.

All broadcasts are (unfortunately) 16:9, which means the 4:3 stuff is
actually 16:9 with black pillarboxing (two Sydney EXPO channels on UHF35 are
an exception to this, they actually broadcast 4:3 material with 4:3 flags,
and I don't have to wear out my aspect button on the STB remote for these
channels).

For you and me with decent TVs that understand WSS, it would be nice for 4:3
stuff to be broadcast with 4:3 flags, and our TVs correct the aspect, but
you will get all those projector owners up in arms here, as for some reason,
despite paying absolute fortunes for their projectors, they often don't
understand the WSS signal in the VBI (that certainly my Topfield TF5000PVRt
sends, along with WSS in the SCART connector).
It would also be nice to send 4:3 stuff with 4:3 flags for anyone owning an
older 4:3 TV that can only watch 16:9 stuff as 4:3 letterboxed, because the
current situation is that these people end up with black around the top,
bottom, left and right (coined "postage stamped") image with 4:3 material.

Yep, luckily the Topfield also has a quick single keypress to swap the modes
too (swaps between 4:3centrecut, 4:3letterbox, 16:9).

Oh yep! Same here. 4:3 TV owners really only need
4:3letterbox,4:3centrecut, and 16:9 TV owners (or people with TVs that
vertically compress to correct the 16:9 aspect on a 4:3 TV like my Loewe
Profil) really only need 4:3centrecut and 16:9.

I was so happy about the Toppy channel changing too. I remember briefly
playing with the original Thompson box and it took ages to channel surf due
to the time for the MPEG to synch back up. The Toppy claims 1sec in the
spec, and certainly this small amount of time isn't too noticable.

I saved a bit of the cricket from my Toppy to my PC via USB2, manipulated it
to a ES with PVAStrumento, and demonstrated 15mins of it to some cricket
loving work mates, and they all want to buy digital STB now! It is nice to
be in widescreen, it is a shame that most widescreen stuff has 4:3 friendly
graphics still, they could utilise the screen real-estate much better, but
still, we get more view of the field, so I am not complaining too much. The
image quality, colour, lack of static, interference etc makes the image
chalk and cheese to the analogue broadcast (esp when the stations are
reducing the 4:3 analogue resolution a bit to 4:3letterbx, 14:9letterbox
or even 4:3 centre cut aspect correct their digital cameras for the analogue
broadcast now).

What EPG are you referring too? Sydney has a couple of extra "program"
video channels (7,9,SBS) that shows whats on, but what would be even better
is if they broadcast the digital EPG (the Topfield can program to record
progs straight off the EPG.
But since they can't get "now and next" completely right at the moment, I
think the full weekly EPG may be a long time away :-(

Thanks for your info, hopefully this year sees a big takeup of digital, and
the networks all start to take digital a bit more seriously (come on channel
4+3, lets get some more widescreen stuff guys!)

Cheers
Tony
