"Official HD-SDI Discussion, Comparisons & Etc..." - Page 2

while I was viewing Fifth Element in those pics I posted I was listening to the TrueHD sound track bitstreamed via HDMI 1.3

HDMI or any other standard output takes care of audio, HD-SDI is just for video

actually professionally HD-SDI can carry audio, but that is not implemented in sources or the inputs on any scaler

-Gary

Josh pretty much explained it all already

all you need is the VP50pro HD-SDI input module, this adds 2 inputs capable of SD and HD-SDI

then all you need to do is get your BD player modified for this output or buy one already modified

thats it and you are ready to rock

I must add that most BD and HD players will have a auto switching 480i SD-SDI output whenever you play a standard DVD in them, the BD30 does not feature this, however there are classic set players that offer the ultimate in DVD performance, so I would stick to one of those and use a separate player for standard DVD, like a Oppo 981, Panasonic RP91, Philips 963a, Pioneer 79avi etc.

-Gary

This depends on the player and the mod. I know the Sony and Pioneer HDSDI modded players simply output the native res of the disc (480/576I for DVD and 720P/60, 1080P/24 or 1080I/50/60 for Bluray - Depends on discs native res).

thanks!

yes, as Krobar said, most BD players will output 480i SDI when playing a SD DVD, however I would go for a known performer for SDI DVD and get a separate player

-Gary

Im new to this HD-SDI , is it alot better than using hdmi? what makes this signal more pure?

direct pure digital signal from the decoder chip, bypassing of all processing like HDCP insertion, color sampling or conveting, avoiding of bit errors, long cable lengths with no worries of signal problems, analog output from scaler, no HDCP BS, highest possible PQ available, direct 1080p/24 4:2:2 output, freeing of HDMI port for audio only

the list goes on and on

-Gary

You lead, I'll follow... again.

I'm interested but notice certain input devices & VP50PRO HD-SDI combos still need mods on both ends.

I'm ready to jump, but would really like a Profile 2.0 player to jump to.

Tim, all issues with the VP50pro and the HD-SDI module have been 100% taken care of, it is working perfect as of now

-Gary

Gary,

Excellent. Thanks. I'm chomping at the bit to grab it + a Profile 2.0 modded player, the latter being the tech challenge it appears. (I'll get over my Leeza SDI + Panasonic DVD bad experiment ).

I think a HD-SDI modified BD50 will be the answer for you dude I look to be doing those soon and will most likely use one in my personal system

then again you may want a Pioneer Elite, which I am considering as well, I miss really nice high-end players

hey what do you think of that SC09-TX?

-Gary

Gary, I really like the new flagship, so now focusing on getting every last drop of video performance (as it will pass through the AVR without being maligned, or audio only to AVR).

The BD50 modded is probably the ticket, but I wll probably wait out the newer Pio flagship players. Concern there is updates which enable features (audio or Profile 2.0, messing up the HD SDI and multi-region "stuff" (Incidentally, I still have my 59TXi DVD (also modded) still cranking away faithfully, even though my Blu-ray and HD-XA2 get all the love these days).

That said, I have caught the HD SDI bug (so to speak)

And now this http://feeds.engadget.com/~r/weblogs.../~3/329472524/

Jitter & Serial Digital Interfaces:

The max allowable specifications for jitter are very strict, no more than 3.7ns for SDI
673ps for HD-SDI, 292M.

HD-SDI employs a signal coding method called NRZI, Non-Return to Zero Inverted. NRZI is a coding method that facilitates recovery of the clock from the actual data transmission. NRZI coding minimizes residual DC component on the signal as well. Due to the construction of this coding scheme, the bit rate is equivalent to the frequency component in MHz. In other words, 1.485 Gbps is equal to 1.485 Gigahertz.

This is what I love about AVS. So many knowledgeable people sharing info. Makes me feel all warm and fuzzy! I normally have to hit our engineers up at work for talk like this, and they eventually tire of dumbing things down to a non-engineering level. Great link.

thanks Mark, enjoyed that very much

-Gary

you heard that beast up against separates? you obviously have it so you must have preferred it, that is one amazing looking piece, then again I always loved Pioneer Elite goods

updates or etc. will never mess with a HD-SDI output mod, you have no worry of that

region free blu-ray mods I can't speak on for sure about that, being this stuff is all hardware it is very very unlikely

-Gary

All the knowledge I posted above & contained in the link belongs to Mr. Somers of Extron. The Kudos go to him.

On a interesting note, how in the hell do we create a comparison scenario
that will make everyone happy?

I can think of very few display devices that accept both HD-SDI & HDMI. There may be a few in the post production world with both but I have not seen them.

Mark, who would complain with say a DVDO VP50pro being fed identical devices one via HDMI and one via HD-SDI, both identical output resolutions for the devices (say 1080i for 2 Panny BD30's via HD-SDI and HDMI), identical setup and calibration for both inputs on the VP50pro

the VP50pro feeding a display device via HDMI at 1080p/60

I don't know how anyone could complain with that although certain folks on certain forums would probably find a way

-Gary

Gary why not just feed the VP50pro 24p from your BD30's HD-SDI and HDMI outputs??...

I agree 100%, I was just using 1080i as a hypothetical in the comparison setup demo I wrote, I think I was thinking that because lots of the test pattern discs(which would no doubt be used in a comparison) are 1080i

-Gary

First true test should be to read an oscilloscope from the same source, a BD30 is fine, and see which provides the cleanest oscilloscope readings.

I know they make scopes that are HD-SDI capable, not sure on HDMI.

Once you go beyond this you begin testing how a VP50Pro handles HDMI & HD-SDI which is certainly knowledge I would like to have as a VP50Pro owner, but of no importance to others.

well to be honest there isn't really anyway to have that kind of comparison Mark as their are no devices out there that are 100% neutral known even par for their HD-SDI and HDMI inputs, no pro monitors that have both that I am aware of, so unless you use a device like the pro or a crystalio or even a blackmagic unit, there isn't really anyway to do a comparison

there are PC input cards for both, but again you are comparing different hardware

-Gary

One of the assumptions I made with a HD-SDI modded BD30 is that the SD DVD would output 480i or 576i 4:2:2 as SD SDI before, getting around the units poor SD performance. However, the JVB units do not support SD over HD-SDI. I presume there are 2 different decoders for HD and SD in Blu-Ray players and you need to apply a mod to both?

Shame that really.

Martin

Martin, BD30 does not support 480i DVD output, that is correct

-Gary

Gary, will it be possible to get 480i and 576i out from other HD-SDI modded BD players do you think?

Martin

Martin there are no other BD players that I know of that don't allow 480i SDI from them, the BD30 is the only HD-SDI modified player that does not allow it

-Gary

I just completed a Onkyo 805 HD-SDI mod, this is a very nice player, especially for the sub 175$ price at shoponkyo recently

HD-SDI output at 4:2:2 1080i (preferred HD-DVD output) is breathtaking as you can imagine, sorry no screenshots guys, my system is down for a upgrade





-Gary

Gary,
That's great. Was thinking about Tosh XA2 modding, if you took units from original owners. May be good just to keep the XA2 as a backup and grab a modded 805
I see the newer BD players trickling in, so hopefully good news from you on that front soon too.

yep BD50 and Denon 3800

-Gary

I still want an LG Bhx00 HD SDI mod !!!! I'll even send you my BH200 that I have not even hooked up to Mod as a test sample !!!
