Editing Set-top box (section)

===Europe===
In Europe, a set-top box does not necessarily contain a [[Tuner (radio)|tuner]] of its own. A box connected to a television (or VCR) [[SCART]] connector is fed with the [[baseband]] television signal from the set's tuner, and can have the television display the returned processed signal instead.

This SCART feature had been used for connection to analogue decoding equipment by [[pay television|pay-TV]] operators in Europe, and in the past, it was used for connection to teletext equipment before the decoders became built-in. The outgoing signal could be of the same nature as the incoming signal, or [[YPbPr|RGB]] [[component video]], or even an "[[local insertion|insert]]" over the original signal, due to the "fast switching" feature of SCART.

In case of analogue pay-TV, this approach avoided the need for a second [[remote control]]. The use of [[digital television]] signals in more modern pay-TV schemes requires that decoding take place before the digital-to-analogue conversion step, rendering the video outputs of an analogue SCART connector no longer suitable for interconnection to decryption hardware. Standards such as [[DVB]]'s [[Common Interface]] and [[ATSC standards|ATSC]]'s [[CableCARD]] therefore use a [[PCMCIA]]-like card inserted as part of the digital signal path as their alternative to a tuner-equipped set-top box.
