Re: Camera Interface Specs

Jamesh, Using an HDMI 2 CSI-2 converter would also satisfy Mgoetzke for having both HDMI in and out to be able to use the Pi as an in line processor even if the Pi could configure the HDMI as an input. Can the foundation sell “dongles” to satisfy the HDCP issue like you do now for MPEG2 decoders? Th...

Re: Camera Interface Specs

Jamesh, Based on this, don’t you think it would make sense to have an HDMI video input on the Pi? As I don’t have access to the video details, I don’t know if you can configure your HDMI connector to be an input. If you can’t, I might be interested in doing an HDMI to CSI-2 adaptor board. What do yo...

Re: Camera Interface Specs

Now, in the “old” days, you could by a SD camcorder with composite video out on an RCA jack. Is there no modern HD equivalent of this?

Re: Camera Interface Specs

Jamesh, Stepping back and looking at the “big picture”, consider this. You provide video out both as SD composite on an RCA connector and HD on an HDMI connector. Thus, any “off the shelf” monitor from the dusty, old black and white sitting in the basement (plus a Radio Shack modulator), to the bran...

Re: Camera Interface Specs

Chatraed, What adds delay is video compression. So if all you were doing was taking video in the CSI-2 port and sending it out the Ethernet (if this implementation of Ethernet is fast enough), there would be very little delay. But if you want to go through any of the video encoders to reduce the dat...

Re: Camera Interface Specs

Dear Pi Foundation, I’ll go back to my earlier proposal, except with a CSI-2 output. I design the circuit and lay out a PCB to take analog component video in and output CSI-2. I will “sweeten” the deal: I will give the Foundation both the schematic and Gerber files. I’ll even throw in the BOM. The F...

Re: Camera Interface Specs

This sounds like a lot more is already available than I thought.

As I said, our camera module is already tuned. So to borrow from audio terminology, I need a driver that is tuned “flat”. And my video is in Y Cb Cr, do we need this “flat” driver to convert to RGB to go into the encoder?

Re: Camera Interface Specs

Jamesh, The only reason that I considered using the HDMI is that you thought that you already had a driver. But I would go back to my original idea of using the CSI-2 port. You tell me what works best for you. I don’t know for a fact if your HDMI port is an input only, output only, or configurable t...

Re: Camera Interface Specs

Jamesh,

I was thinking as you already have an HDMI driver and no matter what, I have to convert my Sony LVDS into so other format, I might as well convert to HDMI and use your existing driver.

Does your HDMI implementation suppory Y Cb Cr?

Jamesh, Thanks, I’ll see what you say Monday. BTW, I don’t need or want this, but from what I hear, there may be a real need for an HDMI input DVR. According to some on video forums, some cable TV companies are trying to make it impossible for people to save content to DVD or even VHS. Some on the v...

Re: Camera Interface Specs

Jamesh, This was my thought. I do an analog component video to CSI-2 adapter / converter board. You grab the CSI-2 data and make several H.264 encoding algorithms available (high quality / not much SD card record time to low quality / lots of SD card record time). Put the SD card video file into a c...

Re: Camera Interface Specs

Jamesh, Actually, I don’t need the Pi board to control the camera. I already remotely control the camera via the RS-232 for remote control of the zoom lens. I use the factory defaults for all of the video parameters. From a block diagram point of view, consider if I simply took the standard definiti...

Re: Camera Interface Specs

Jamesh, I am a hardware engineer. I already expected to have to do an "adapter" board. The Sony outputs HD digital on 4 7 bit LVDS channels. I noticed the camera connector only brings two I think LVDS data inputs and an LVDS clock input out. And I expect impossible to tack solder wires onto the Broa...

Re: Camera Interface Specs

The camera that I want to use is a Sony FCB-EH3150. It is a camera module, more than just the CCD. HD outputs in Analog component or digital LVDS. I think a lot of the "tuning" is already done in the camera. I want to use the Pi board to run a high profile H.264 encoder to get data rates down to the...

Camera Interface Specs

Hi, I want to interface a different camera to the Pi primarily because the camera that I want to use has a zoom lens. It looks like you have two LVDS data inputs and an LVDS clock input on connector S5. How much information can you give about this connector specification without hurting your Broadco...
