3.3.5.3.2.10 Processing a Set Video Source Rectangle Message

The structure and fields of the Set Video Source Rectangle message are specified in section 2.2.5.2.10.

After receiving the Set Video Source Rectangle message, the client SHOULD render only the parts of video specified by the normalized rectangle. If the client has set the CapabilityType field in TSMM_CAPABILITIES (section 2.2.6) to 0x00000002 or a lower number, the client MUST ignore this packet.

If this message is not sent by a server, assume the default rectangle to be {0, 0, 1, 1}, which corresponds to the entire video image.
