Speaker 1: dot com where smart Happens. Hi, I'm Marshall brain with

8
00:00:28,720 --> 00:00:33,240
Speaker 1: today's question, how's your radio able to display the station's

9
00:00:33,320 --> 00:00:37,560
Speaker 1: call letters and things like song titles on the radio's display.

10
00:00:38,320 --> 00:00:41,200
Speaker 1: If you have one of those radios that show FM

11
00:00:41,360 --> 00:00:44,720
Speaker 1: station call signs right on the display panel, then you

12
00:00:44,840 --> 00:00:49,080
Speaker 1: have what's called the radio data system feature with your radio.

13
00:00:49,640 --> 00:00:53,680
Speaker 1: The Radio Data System or RDS, is available in many

14
00:00:53,840 --> 00:00:57,080
Speaker 1: US cities. There's a similar system in Europe as well.

15
00:00:57,680 --> 00:01:01,680
Speaker 1: In the United States, each FM radio station is allocated

16
00:01:01,760 --> 00:01:05,640
Speaker 1: two herds of bandwidth. So if a radio station is

17
00:01:05,680 --> 00:01:09,119
Speaker 1: at ninety three point one on the FM dial, its

18
00:01:09,160 --> 00:01:13,240
Speaker 1: frequency is ninety three point one million herds, and it

19
00:01:13,319 --> 00:01:17,160
Speaker 1: has between ninety three point one and ninety three point

20
00:01:17,240 --> 00:01:21,560
Speaker 1: three million hurts as its allocation. The station doesn't fill

21
00:01:21,680 --> 00:01:24,880
Speaker 1: all that bandwidth with music there's some space left over

22
00:01:24,959 --> 00:01:30,000
Speaker 1: on both sides. RDS is a completely separate radio signal

23
00:01:30,400 --> 00:01:34,920
Speaker 1: that fits between the station's frequency allocation. It's like there

24
00:01:34,920 --> 00:01:39,679
Speaker 1: are actually two radio stations broadcasting. One has music and

25
00:01:39,680 --> 00:01:44,199
Speaker 1: the other has data. The RDS signal carries digital information

26
00:01:44,280 --> 00:01:48,440
Speaker 1: with a data rate of about eleven hundred bits per second.

27
00:01:48,920 --> 00:01:54,200
Speaker 1: RDS transmits data simultaneously with a standard FM radio broadcast.

28
00:01:54,680 --> 00:01:57,280
Speaker 1: Your radio picks up the music and sends it to

29
00:01:57,320 --> 00:02:00,360
Speaker 1: the speakers, and then it separately picks up the data

30
00:02:00,440 --> 00:02:04,800
Speaker 1: signal and sends that data to the display. Possible uses

31
00:02:04,840 --> 00:02:10,240
Speaker 1: include transmitting song titles, station call signs, and signaling when

32
00:02:10,320 --> 00:02:14,720
Speaker 1: traffic and weather reports are being broadcast. For more on
