i want to interface a webcam with PSoC 3 and then transmit the webcam video to recevier side..how can i do this..
What kind of webcam are you trying to interface with PSoC3. USB?
actually in my project i want to transmit video to other end ( receiver) wirelessly.. This video will be captured by a webcam and i will be using PSoC 3 at both transmission and receiving end.
ya i will connect webcam to PSoC with USB.. Please guide me with all considerations and your suggestion that i should take...
I dont think it is possible to connect a webcam to PSoC3 or PSoC5 via USB. PSoC does not have a USB Host capability and hence a USB cam(assuming the camera is a USB perihperal) can not be connected via USB.
Assuming that it is connected video over USB is tough because we are fundamentally limited by the bandwidthe available on USB; PSoC3/PSoC5 support only Full Speed transfer and a maximum of around 1 Mega Byte/Second. So even if you have a 1Mega Pixel camera, you wil have approximately 3 Megapixels of data in one frame and depending on the framerate you will have more data. So connecting awebcam to PSoC3 and streaming video via PSoC3 is out of question.
That said, Cyoress makes some awesome chips which can do this. There are specific USB devices which can do this, will gather more information and post it here.
so it means we cannot connect a webcam with PSoC through any other means also....
Your best bet would be to find if there is someother camera which can throw out data on a different protocol. SPI or may be some other parallel bus would definitely help.
Sir, my project is "Wireless Video transmission through Webcam" in this i need to transmit video of a camera from one end to other without a physical connection between them....please guide me how sholud i proceed....
First, before decide for PSoC 1, 3 or 5
To transmit (any) data you need something named "Protocol". It specifies in which format etc what data is transmitted. When you lean on the OSI-layer model (ask mrs. Wiki Pedia if you don't know it), you see that the lowest layer actually defines the transmission media, which is in your case RF.
Give that layer-model a bit of thought, it will make the implementation easier. Later on the protocol-layer will be implemented on your PSoC.
You must give attention to bandwidth and byte throughput because uncompressed video has a lot of data and compressing is not an easy job. So sharpen your pencil, thake a sheet of paper and start calculating...
In my opinioin, there are 2 pieces that form this puzzle. First, trying to get data i to PSoC from a webcam(a camera in general). Second is the transmission part.
If using a digital webcam....wat are the types of formats video webcam available like RGB or such.......or which can be interfaced with controller...
