Definition of HScreen
The site http://www.interactivetvweb.org defines HScreen as
"AVi (and OCAP) defines an HScreen class to help solve this problem. This represents a physical display device, and every receiver will have one HScreen instance for every physical display device that's connected to it - typically this will only be one."
I don't think HScreen represents a physical device. Assume a STB has more than one video output ports and there are more than one physical device connected to it, then is it logical to return as many number of HScreen devices?
My answer would be No.
The javadoc of HScreen class says
"This class describes the final output composition of a device. It ties together all the (MPEG) video decoders, all the graphics sub-systems and backgrounds which are all combined together before finally being displayed"
Hence, the number of HScreen instances should depend on the number of independent displays that the STB can come up with.
Kindly evaluate my understanding.
