I might be talking out of my armpit here but when you check the operation of the RGB scart do you have to disconnect the HDMI first, as not doing so disables the scart output?

GC, I'm not sure what you mean by this in relation to the HDMI/Scart issue? (I'm probably being thick Hi Savvy no I missed your edit.![]() ![]() )Also, did you see the Edit/Question in my post? Rgds. Les. Quote:
I've no idea
![]() Edit : Do you mean it disables the RGB over Scart, or disables the Scart? Rgds. Les. I thought I would mention this issue on removing the HDMI as when I first got my HDR I thought I would connect the old HD box to an CRT in the living room and knowing that when it was previously connected to the LCD in the conservatory I had toggled the source button to disable the scart output.. so on setting up on the CRT I decided to use a long HDMI that I have to connect to both TVs at once just so that I could see what was going on .. Having then toggled the source button to display on the CRT I happened to scroll through the channels and landed on BBC HD and I got a message along the lines of scart output is inoperable due to permission/rights or something. You'll have to forgive me it's a long while ago ![]() ![]() Anyway later on a month or so on I connected the HD box to the CRT again and this time no HDMI and Bingo picture on BBC HD. Obviously it couldn't have been RGB back then but presumably composite via scart. But as I say that was the thinking about removing the HDMI |

Nope - SCART works fine with HDMI in. On my Panasonic TV anyway.

In fact HD over component looked awesome (better then hdmi at least on my TV), until a firmware upgrade crippled the HD component (and RGB SD)
![]() ![]() HD Component looked much better than HDMI to me as well. But still, we have to suffer these things because of those pesky pirates, who would jump at the chance to make life really difficult for themselves by using component signals...

Doesn't HD over component still work in non-freesat mode? It did on my non-PVR foxsat with component disabling f/w. (I've replaced it with a non-freesat box so I can't easily check if there have been further party-pooping updates.)

Given the above facts, if power is applied at any level and the CPU is active and, if (and its a big "if"!) the firmware/software is written correctly/well, it ought to be able to carry out any task at any time concurrently!! If it can't do this, then frankly, it is rubbish!!

Yep, and remember this isn't a general purpose PC-type processor in these boxes. It's a SoC device, which is used to help keep the costs down to a reasonable level, and hopefully to increase reliability.
The Broadcom chip use has a MIPS core, which runs the OS and has the job of looking after things like the UI, EPG, IO via integrated PCI and so forth, while the 'other side' of the chip does the grunt work, including PID filtering, video codec work, and graphics output. The MIPS core runs at 300MHz, which is sufficient for the day to day operation; it compares with, for example, the 167 or 133MHz core in SD Freeview PVRs like the Humax 9200 and Topfield 5800. USB transfer is fairly CPU intensive; but that's about the only issue that you get using devices like this; speccing up an x86 type system with the equivalent functionality is likely to result in a much higher cost, and probably be harder to code for too, with the only real consequence likely to be better USB performance. |

If the CPU &/or IO subsystem were not fast enough to do the multi-tasking adequately then it would be reasonable for the software to prioritise the tasks.

The only one I know of is the 2am Freeview EPG update which I think is more to do with the mechanics of the transmission than it is the box itself and even then, it still happens even if you have the box on and in use? The fact that the HDR can't mimic all this in the way that it operates must surely be everything to do with the way that the software is written? |
