Direct answer
Yes. A correctly sized video-distribution system can send one source to multiple displays or different sources to different displays. The number of independent programs depends on distribution capacity, available source devices, tuners, and service-account rules. Four televisions do not automatically require four cable boxes, but four viewers requesting different cable channels usually require four independently tunable sources.
Streaming providers may limit concurrent sessions. Control programming should make source ownership and availability clear so one user does not unexpectedly change another room. Document common modes—independent viewing, whole-home event, patio and great-room grouping—before choosing the matrix and number of sources.
