WEBVTT 00:00:00.000 --> 00:00:05.460 thanks for watching techwiki click the Subscribe button then enable 00:00:03.360 --> 00:00:10.320 notifications with the Bell icon so you won't miss any future videos so you've 00:00:07.859 --> 00:00:14.759 bought yourself a fancy new TV you've plugged in the power cord and an HDMI 00:00:12.360 --> 00:00:18.900 cable for your cable box and Bam you're ready to go but hold on a minute what's 00:00:17.220 --> 00:00:23.100 this Festival of multi-colored connectors on the back what are those 00:00:20.699 --> 00:00:29.340 even used for I mean those are basically everything use HDMI these days well 00:00:26.160 --> 00:00:31.320 while HDMI has superseded a lot of older 00:00:29.340 --> 00:00:35.040 standards those other Jacks can still be quite useful So today we're going to 00:00:33.300 --> 00:00:39.180 demystify the little ports you might find on the back of your TV or your AV 00:00:36.960 --> 00:00:44.460 receiver starting out with a venerable RCA connector this thing is named for 00:00:41.820 --> 00:00:48.539 the old radio Corporation of America who originally designed it as a simple 00:00:45.840 --> 00:00:53.399 analog connection for audio devices and actually goes all the way back to the 00:00:50.100 --> 00:00:55.379 1940s but because of its versatility and 00:00:53.399 --> 00:00:59.940 simplicity it still surprisingly common on Modern Electronics on the TV or 00:00:58.140 --> 00:01:04.559 receiver you're likely to find at least a pair of them one white and one red 00:01:02.460 --> 00:01:08.880 which correspond to left and right analog stereo audio channels 00:01:06.479 --> 00:01:13.140 respectively RC audio is still quite popular as it makes simple tasks like 00:01:11.280 --> 00:01:17.100 connecting a pair of speakers to your TV once you get sick of the tinny built-in 00:01:14.760 --> 00:01:21.960 audio rather straightforward but you may also see the grouped with a yellow Jack 00:01:19.200 --> 00:01:26.159 which carries composite video this supports a standard definition analog 00:01:24.119 --> 00:01:31.979 video signal and can be found on tons of VCRs DVD players and game consoles prior 00:01:29.640 --> 00:01:36.060 to the late 2000s so while composite video has fallen off in popularity due 00:01:34.200 --> 00:01:39.840 to its limited resolution and the fact it's more susceptible to interference 00:01:37.560 --> 00:01:44.100 than modern standards is still useful if you want to dust off the old N64 and 00:01:41.939 --> 00:01:49.140 enjoy some Ocarina of Time on your flat screen which isn't to say it's the best 00:01:46.500 --> 00:01:53.399 way to enjoy your retro games if your TV happens to have one of these dude as 00:01:51.000 --> 00:01:58.439 congrats you've got support for S video the idea behind it was that instead of a 00:01:55.920 --> 00:02:01.740 single conductor it had two using one for brightness information and another 00:01:59.880 --> 00:02:05.399 are for color now this cut down on interference and improved picture 00:02:03.180 --> 00:02:09.479 quality it was once popular on DVD players and even on some game consoles 00:02:07.320 --> 00:02:15.780 but it enjoyed only a very short time in the sun eventually getting mostly phased 00:02:11.580 --> 00:02:18.300 out in favor of what RCA again yeah so 00:02:15.780 --> 00:02:23.340 if you spot a green blue and red set of RCA jacks next to each other your device 00:02:20.400 --> 00:02:26.520 supports component video the idea here is similar to S video except that the 00:02:25.319 --> 00:02:31.020 green cable carries brightness information while the blue and red 00:02:28.560 --> 00:02:34.800 cables both carry color signals blue and reds respectively which makes a lot of 00:02:32.760 --> 00:02:39.540 sense right separating the signals out improves image quality even further and 00:02:37.140 --> 00:02:43.260 even enables high definition output component video was common on game 00:02:41.220 --> 00:02:49.200 consoles like the Xbox 360 and Playstation 3 for HD output to TVs 00:02:45.780 --> 00:02:51.120 before HDMI became super widespread and 00:02:49.200 --> 00:02:56.420 that brings us at last to the final thing you'll commonly see RCA connectors 00:02:53.099 --> 00:02:58.800 used for digital audio like Dolby 5.1 00:02:56.420 --> 00:03:03.420 usually it'll have a label that says coaxial on it but it should not be 00:03:01.260 --> 00:03:07.260 confused with the coaxial connector for cable TV service or an FM antenna 00:03:05.580 --> 00:03:11.280 because that's a totally different kind of cable the audio coaxial cable is 00:03:09.660 --> 00:03:15.599 built to a different internal spec than running the mill RCA audio cables but in 00:03:13.739 --> 00:03:20.519 practice you can probably get away with using a garden variety RCA cable as long 00:03:18.000 --> 00:03:25.140 as it isn't too long or you could just use this thing called a toslink 00:03:22.560 --> 00:03:28.980 connector for digital audio toslink is actually an optical standard so it uses 00:03:27.480 --> 00:03:32.879 light to transfer data over a specialized cable hence the reason 00:03:30.659 --> 00:03:37.440 tosslet connectors often glow on the back of your TV or receiver another 00:03:35.040 --> 00:03:41.280 Audio Only standard is the familiar 3.5 millimeter Jack for connecting 00:03:39.060 --> 00:03:46.620 headphones speakers which you'll find on computers audio players and older 00:03:44.340 --> 00:03:50.159 smartphones some equipment uses the larger quarter inch stereo connector 00:03:48.180 --> 00:03:55.080 which has the same functionality moving away from audio you may also find this 00:03:52.379 --> 00:03:59.459 dsub VGA connector which was very common on older computer monitors but since 00:03:57.239 --> 00:04:03.659 it's an analog standard it's more prone to interference so modern PCS have 00:04:01.860 --> 00:04:07.019 largely ditched it in favor of digital standards we felt like we needed to 00:04:05.280 --> 00:04:10.680 mention it anyway though because it's still included on some TVs and many 00:04:09.000 --> 00:04:15.120 projectors in case you need to connect something like an aging laptop now of 00:04:13.019 --> 00:04:19.680 course you might bypass using all of these and just go with this thing the 00:04:17.400 --> 00:04:23.580 HDMI connector which supports both high def video and audio along with 00:04:21.780 --> 00:04:27.660 networking on the same cable and although digital coaxial and toslink can 00:04:26.100 --> 00:04:33.479 only carry traditional surround sound like Dolby Digital and DTS only HDMI 00:04:31.139 --> 00:04:38.400 supports lossless floor mats like Dolby true HD and DTS Master audio the newest 00:04:36.600 --> 00:04:43.020 revision support High resolutions and refresh rate outputs as well as HDR for 00:04:40.860 --> 00:04:47.820 more realistic images a feature also found on HDMI's PC Focus competitor 00:04:45.660 --> 00:04:51.840 DisplayPort now on the subject of surround sound these aren't common on 00:04:49.860 --> 00:04:56.040 TVs themselves but if you have an AV receiver it's likely you'll find a Bank 00:04:53.880 --> 00:05:01.380 of old-fashioned two conductor speaker wire outputs for your speakers this tab 00:04:59.040 --> 00:05:05.520 style is normally found on the lower end and can also be used for AM radio 00:05:03.300 --> 00:05:09.780 antennas but if you go more fancy they'll probably look a little bit more 00:05:07.380 --> 00:05:13.320 like this now there are a couple of ways to connect to these guys either by 00:05:11.520 --> 00:05:18.000 stripping the wire and screwing it into place or by picking up some of what are 00:05:15.780 --> 00:05:24.120 called banana plugs and simply plugging them in as for the 0.1 of your however 00:05:21.180 --> 00:05:29.940 many 0.1 audio setup Standalone subwoofers usually still use RCA yeah 00:05:27.419 --> 00:05:34.680 when I said we were done with RCA I um I lied sorry now the funny thing here is 00:05:32.280 --> 00:05:40.380 that RCA isn't even the only shockingly old connector you'll find on the back of 00:05:36.360 --> 00:05:42.240 a receiver this rs-232 serial Port can 00:05:40.380 --> 00:05:46.979 be used both for firmware updates and hardwire remote control for folks who 00:05:44.280 --> 00:05:51.419 find infrared just not reliable enough for some reason and finally and this is 00:05:49.259 --> 00:05:55.740 true of both receivers and TVs you'll usually find some USB and Ethernet ports 00:05:53.460 --> 00:05:59.400 on Modern AV Equipment they can both be used for firmware updates and USB is 00:05:58.020 --> 00:06:04.860 great for everything from streaming media content to charging your game console controllers while Ethernet is 00:06:02.820 --> 00:06:08.160 for well I mean I don't think I really have to explain this but I'll do it 00:06:06.360 --> 00:06:11.400 anyway for the sake of completeness you can use it to connect to the Internet so 00:06:09.660 --> 00:06:15.780 you can stream content from online apps integrate with digital assistants and 00:06:13.500 --> 00:06:19.199 browse the internet if you're just a sucker
