ust a short note about my viewing of the Rock. Some of you may be aware I was down in London on Sunday/Monday/Tuesday. Monday and Tuesday were business. The Tuesday being the launch of Christie Digital's (Electrohome) partnership with Marata Vision for Home Theater projection. I'll post about that in a seperate thread. On Sunday though I popped in to see Neil Jenkins and have a look at a Rock. First off let me say that Neil is a TOP host. I was knackered, sweating and disheveled after a 5 hr drive and his first words were "Can I get you a cold beer?" Excellent.......... We had a couple of other things to chat through and it was late by the time we managed to get round to looking at the Rock. As I'd never seen an HTPC working Neil knocked one of those together out of some bits so I could get an idea of how it compared. Once again it should be noted this is not exhaustive just some initial impressions. It's a bigger box than I was expecting. Then again it's based on PC architecture so you'd expect it to come in a PC size case I suppose, and it does. It has some great great features. Chroma delay is very useful for a start. It's aspect ratio control is good but the ace in the hole are the multitude of output resolutions and scan rates. We compared 72Hz refresh to normal 60Hz with NTSC material to see if it really does reduce judder. It does, although stangely it doesn't elminate it. In sections of a film where previously it was obvious and annoying it now becomes less obvious but still there in parts. This is something I'd like to investigate I suspect it's because it shouldn't be 72 Hz but some strange figure of 71.xxxxxxxHz. Neil played a piece from Toy Story 2 for this dem, that showed it up well. The Star Trek Insurrection scene did too. I'm pretty sure we only watched NTSC film based material so de-interlacing is based on that. The two torture tests we used were Gladiator,"battle of carthage" and the aforementioned Star Trek. Gladiator fared very very well. Only falling down at two sections. They are further in to the scene than I usually go though so I need to check on other units how this compares. Star Trek however didn't do as well as we had hoped. I was actually surprised and somewhat disappointed by this. Again I need to go away and re-check with my reference but I felt that even the Skyworth pulled the de-interlacing of that scene off better, as did the Vigatec VC1280. The smooth panning of the camera was much improved though due to the 72Hz refresh. We tried this scene on the HTPC. I found my perception of the level of detail in the image on thes two scenes was higher on the HTPC. They both performed identically on de-interlacing though. The only other weird thing that came up is that the Rock doen't auto detect the incoming video standard. So if you've been watching a region 1 DVD and you switch to a region 2 one or to normal TV then you need to go and tell it to expect a PAL signal. If you have a learning remote with macro facilities I believe you could have NTSC and PAL buttons but the fact you have to do it means it's not seamless in operation as every other scaler or de-interlacer I've used is. The Rock intruiged me. For those wanting close to HTPC performance without the hassle then it could be a go-er. From an installer's point of view the inability to auto detect PAL and NTSC is a big problem for me......perhaps they'll fix it in the Rock +. Gordon <br />May I point out that in my day job I work for a company that sells the "competition" to the Rock. IE The VigatecVC1280. <br />My own consultancy Convergent-AV supplies Quadscan's (the device that caused TAW to develop the Rock, I believe)<br />If you are considering a hi-end scaler then you should seek one out and dem it for yourself...along with some of the competition.
