However, some have considered switching to <a href="/wiki/DVB-T2" title="DVB-T2">DVB-T2</a> such as the <a href="/wiki/United_Kingdom" title="United Kingdom">UK</a>, being the first to test DVB-T2. This results in a number of different combinations for external digital receivers with the MPEG-2s sold at about €15 to €35 and the MPEG-4 ones reaching €25 to €150. Currently, all set top boxes sold in the EU cannot exceed 0.5 W in standby mode. </p> <div class="mw-heading mw-heading2"><h2 id="Other_countries">Other countries</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Digital_television_adapter&action=edit&section=5" title="Edit section: Other countries"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Some countries have also introduced digital television and ended analog over-the-air transmissions. Most new TVs feature a digital tuner which allows reception of digital over-the-air TV without need of an external device such a converter box. If using a TV set without a digital tuner, an external converter box must be purchased and used. A converter box takes the digital signal from the antenna and outputs <a href="/wiki/Composite_video" title="Composite video">composite video</a> (for SD TVs) or <a href="/wiki/HDMI" title="HDMI">HDMI</a> (for HD TVs). A RF/antenna output, if present on a converter box, is usually just a <a href="/wiki/Passthrough_(electronics)" title="Passthrough (electronics)">passthrough</a> ("LOOP OUT" which does not provide the box's output signal, but only provides the raw antenna input signal to watch analog channels via a TV set's tuner if analog broadcasts have not ended yet or to connect another capable device to the same antenna feed) because even older TVs usually have at least composite input; this removes a need for an <a href="/wiki/RF_modulator" title="RF modulator">RF modulator</a> in a converter box. </p>
