Hi,

Thanks for your help in answering my previous questions about the ET box. I am now planning on buying the Sanyo HD receiver, that is sold at the Warehouse for 199.00 (http://www.sanyo.co.nz/products/tvs-set-top-boxes/hd-set-top-boxes/tuhd10100).

So, what is is like? How sensitive is the signal? Can it do full 1080p or just 1080i? Does it have any pixelation issues or sound drop outs?

Thanks for your help,
Jordan

Considering that the highest quality signal currently broadcast on Freeview is 1080i (TV3), I doubt many if any of DVB boxes in NZ would do 1080p.

Someone may know whether 1080p is even part of the Freeview specs.

Does this Sanyo have any ability to act as a PVR (ie, to enable and manage recordings)? If this is a feature you think you may use, and the Sanyo doesn't have it (as I suspect), perhaps look at a PVR-ready model.

I dont believe that 1080p is part of the NZ freeview specs. Apparently overseas it is (to quote wikipedia) "very rare". Its very heavy on bandwidth.

I am pretty sure that no other freeview box specs that I have seen ever mention more than 1080i.

Hmm. I don't believe that there are any PVR boxes (well, official ones), because Freeview will only want you to be able to record with a MyFreeview|HD box.

Well, if Freeview doesn't have 1080i, then I'm not missing out on anything if this box doesn't have it :P

Freeview does have 1080i - that's interlaced, and therefore needs considerably less bandwidth than 1080p, which set-top boxes don't support!

Any particular reason why it must be Freeview approved? Actually, I think the JC Matthew unit (I think that's the brand - check out the relevant thread here) is both Freeview approved and can become a PVR with a firmware update available off the net. I guess they get around this by not selling it out of the box as PVR-ready. The Vantage, which I've got, is a pretty good unit; the biggest downside is the lack of the MHEG5 (7 day) EPG, which may be a necessity for you. Unsure about the JC Matthew box, but assume as a Freeview-approved unit it must have the MHEG5 EPG (though also unsure if it uses this for establishing recordings).

No STB supports 1080p.

1080p will never reastically ever exist in a broadcast format due to the bandwidth requirements. The economics of using it simply don't stack up.

Gee Steve, never is quite a long time

. What is being done with MPEG4 at the moment was probably considered outlandish when everyone was watching 21" Philips K9s

OT but Zinwell box with HK firmware has a 1080p/24 output option. Not sure if it supports 1080p decoding though.

When I say broadcast I mean OTA using DVB-T or DVB-S.

If you're running a cable network then using an entire DVB MUX to transmit a single channel is an option and has been done. Likewise streaming 1080P content over a DOCSIS3 cable network to a STB is also very easily done.

The reality is you can't compress 1080p content much further without suffering greater losses unless somebody magically creates a lossless compression codec for video. If you're going to compress 1080p much further to save bandwidth you may as well transcode it to 720p!

I have got one of these Sanyo STB's

Generally it seems to be very good. I do get occassional bursts of pixelisation, but I suspect these are due to my aerial being below par rather than the unit itself. Dont get sound drop outs at all. Could not tell you if it is 1080p capable, my TV set ( a four year old Chinese made LCD) isn't 1080p capable anyway
