HD-SDI v.s. HDMI
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).
