How about a device such as the Intel IPU3 ? It's a SoC, and is present
in laptops. Unlike the physical interface which is a fairly well defined
way to categorize devices, creating artificial classes will always leave
some devices without a home. We could have a capture card that supports
both analog and digital TV. A digital TV capture card with an HDMI input
can have a CEC device. Lots of combinations are possible.
