 This component wraps the ISP (Image Sensor Processor) hardware block to
 offer hardware accelerated format conversion and resizing.
+It has one input port taking Bayer, YUV or RGB images in numerous different formats.
+It has two output ports:
+Port 361 supports various RGB and YUV formats.
+Port 362 is off the low res resizer which can only downscale. Due to this
+port 362 must be at a lower resolution to port 361. If set to a higher resolution
+then the port will effectively be disabled and no ouput produced. It also doesn't have
+the colour conversion block, and so only supports YUV formats.
+<p>
+Port 361 is treated as the main output - the pipeline will stall until an output
+buffer is available on that port. That includes if port 361 is disabled then no
+processing will occur.
+If no output buffer is available on port 362 when both an input buffer and
+port 361 output buffer are available, the frame will be processed with the low
+resolution output disabled.
 <p>
 Please note that this component has been developed for use under MMAL. It has
 not been tested at all under IL, so there may be unexpected behaviour under IL.
-It is also not considered to be production quality code - please use with caution.
