HD-SDI v.s. HDMI
on Feb 23, 2009 at 8:58:07 pm

Got a question for anyone out there who wants to clearify something for me..... In the professional industry we are using HD-SDI cables to capture footage uncompressed. In the consumer world we are using HDMI to watch televison from our cable/Blu-Ray ect....

Why is this?

Why are we using HDMI and not HD-SDI on our consumer products?


HD-SDI cables can carry more information; 16 channels of embeded audio oposed to the 8 channels that HDMI carries.

Both carry a digital video and audio signal and HD-SDI cable is significtly cheaper.

Again just looking for someone to fill me in on why this is.....

Thank You

Micah

[Micah Wolf] Why are we using HDMI and not HD-SDI on our consumer products?

The HD-SDI specifications don't allow for HDCP. HDCP is THE reason we have HDMI in consumer products.


HD-SDI cables can carry more information; 16 channels of embeded audio oposed to the 8 channels that HDMI carries.

HDMI v1.3 has about 3-times the bandwidth of HD-SDI dual-link or 3G.

But when professional video needs something more than HD-SDI, XD-SDI (or what have you) will be created with 128-bit color, 12K resolution, and 256 channels of 384kHz/48-bit audio (insert tongue in cheek).
