A small number of TV receivers were also manufactured with built-in broadcast radio receivers these included some small portable devices or (more rarely) sets marketed for hotel/motel use. In the US, this primarily affects low-power and broadcast translator stations, as these are exempt from the FCC mandate to switch to digital broadcasting in 2009, as well as foreign signals that will remain in analog form.

With a box that lacks analog passthrough, no other signals are sent to the output, so all analog stations are lost. Any converter box converts the digital signal for the current digital sub-channel to an analog signal (at the reduced screen resolution of the analog standard), outputs that signal onto analog channel 3 or 4 (set by the user to avoid any conflict with local over-the-air channels) and sends that signal to the analog tuner in the TV. European VCRs did not turn off the passthrough when the unit was on – instead, the VCR added its output as an extra channel (usually 38 it was possible to change the output channel, depending on the model, by turning a screw in the back of the VCR or by selecting an appropriate option in the OSD menu).Īll digital-to-analog converter boxes have both an antenna input (which accepts the coaxial cable that formerly went directly to the TV) and an RF output (which now goes directly to the TV). Passthrough was turned off when the RF modulator (typically on TV channel 3 or 4 in North America) was on, as this F connector was originally the only way to send the VCR output to older TVs, until unmodulated composite video and RCA connectors became common. Those with analog passthrough allow both digital and analog television to be viewed on older TVs.īefore digital television, passthrough originally existed for VCRs (and later PVRs and DVDRs), allowing the TV antenna or cable TV signal to pass through the VCR (with a slight insertion loss) to the TV set automatically when the VCR was turned off, or manually with a button on the remote control. Boxes without analog passthrough only allow digital TV ( ATSC standard) to be viewed on older, analog-only ( NTSC standard) TVs.
