Title: Analog to IP Video Converter
Post by: techneo on January 31, 2020, 06:43:39 06:43
Hi,

 I have three analog cameras installed in one building and i want to transmit these videos over LAN to a second building. I wanted to start with converting the analog video  to digital video and then input it to the CSI port of Raspberry Pi which would convert it into IP format.

What i will do is try to convert the analog video into digital video format using TVP5150AM from TI.

http://www.ti.com/product/TVP5150AM1-EP?keyMatch=VIDEO%20ENCODER&tisearch=Search-EN-everything

OR

 do the conversion using ADV7280.

   https://www.analog.com/en/products/adv7280.html

Now the next problem is how to convert from YCrCb format to CSI format?

I have the following further options :

  1. Convert the YCrCb to HMDI and use a HDMI to CSI Bridge.

           https://auvidea.eu/b101-hdmi-to-csi-2-bridge-15-pin-fpc/

    But this bridge is very expensive and not feasible for serial production because of cost.

Since i have no previous experience of doing this , i just wanted to confirm from any board member  if the path i have chosen is good to follow or i make some diversion?

Regards

Hi I have worked with TI TVP5150 nice chip - you will also need a pre amp in front of each channel
You can use any  microcontroller who have a digital camera interface (STM32 F4 & F7 , I.MxRT10x0 )to sample the YcrCb signal and send it via Ethernet.

it is a rather complicated project as to buy a wireless LAN camera cost less then $20

All the best

Hi Bob

  I genuinely appreciate your help...
 However, my limitation is that the legacy cameras having analog output can only be modified and cannot be changed altogether. So i guess i need to get hold of TVP5150 to get the job done.

Here's exactly what you need: https://www.renesas.com/us/en/products/audio-video/video-decoders-encoders/video-decoders/device/ISL79987.html

The TVP5150 have analog video input

All the best

Probably the cheapest solution is to use an NVR with analog inputs.
Some chinese dealers claim to give also an SDK, so you can customize firmware with your own application

Why not just buy a box that takes analog video in and puts out TCP/IP video? They're not expensive.

Disregard if you really want to do a "build it yourself" project. Otherwise, this seems a lot easier.

yes its seems interesting  :)

The only constraint that i have is for accommodating the converter in a very tight space. That's why i want to go for a fully customized solution.
