Refer to the exhibit. In the SDP that is displayed, to which IP address and port should the receiving end send its content video channel media?

192.168.1.4:2048 corresponds to the address and port of a different media stream section in the SDP, not the content video channel.

192.168.1.4:50000 references the wrong IP address for the content video channel; the correct address for that stream's c= line is 192.168.1.5.

192.168.1.5:50002 uses the correct IP address but references the wrong port number, which belongs to a different media stream than the content video channel.

SDP describes each media stream in its own section beginning with an m= line that specifies media type and port, paired with a c= line specifying the destination IP address for that stream. The content video channel in the exhibit is represented as a separate video media section with connection address 192.168.1.5 and port 50008, so the receiving end must send its content video media to 192.168.1.5:50008 as defined by RFC 4566.
