How to send CVImageBufferRef over the network in iOS?

Question

Hi, I want to send a CVImageBufferRef I got from

- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection{
CVImageBufferRef imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer); }

over the network using NSOutputStream's write:maxLength: method.

Anybody can give a simple example to achieve this? And also to read the sent data at the receiver?

Thanks.
