Live SD stream from Nano - any advice
I am still trawling through the Nano and Sony manuals/ FAQ's etc but have come uo for a breath of air and help.
What I want to do is get 1050i HD signal from my EX1. and convert it to a 50 Mb SD signal out to a SMPTE SDI live stream ingest point with little or no latency. I don't necessarly have to record onto the CF so the E to E option may come into the fold ? Has anybody done this? Also, some elementary guidance on changing the Nano settings for the above would be really great. I think I have got an information overload problem going on - my head is a but numb at present. Whilst I am on about it, has anybody used an Osprey HD/SDI capture card in conjuction with a Nano or EX1/3 . This is test for another day though. Jeff |

Re: Live SD stream from Nano - any advice
Not sure an HD-SDI stream can be anything other than 1.5Gbits/s... what are you hoping to do with a 50Mb XDCam stream, if you can manage to get one down an HD-SDI cable?

Re: Live SD stream from Nano - any advice
Basically, I am trying to find out if I can improve the EX1 HD to SD conversion which comes out as an SDI signal.

Re: Live SD stream from Nano - any advice
I suspect since the nano uses a Sony chipset for encoding that you are going to see similar results as setting the EX1 SDI output to SD.

Re: Live SD stream from Nano - any advice
Dear Jeff,
I am sorry, but the nanoFlash does not perform downconversion of HD to SD. I undertand that you want to take HD-SDI in and output SDI (SD-SDI).

Maybe I shoud explain here. A couple of weeks ago, I took the EX1 to a permanent Live News location (Parliament ) here in London, UK. , At the end of the news report we unhooked the Sony DSR 450 and patched in the EX1 via BNC and scooshed out an SDI siganl to the news gallery. A very tired Technial Dirctor (TD) reported that he was receiving the pic and sound in synch and it loooked OK I then bought a NanoFlash for use on Corporate and posh two camera HD interviews. I started to wonder if I could improve the picture quality of the SD - SDI output with the help of the Nano. Basically I am trying to get the best picture quality with my kit as I have yet to do a full test when I can pin the TD down. |

This is probably out of your remit but do you or anybody else know what the Sony EX1 process for HD to SD - SDI involves. I think it is just an HD to SD down conversion complying with a SMPTE 2590 SDI standard. |
