Mehmet Göktürk 11 Ocak 2017 Yazar Paylaş 11 Ocak 2017 Almanya'da istasyonlar trafik alarm kanalına bağlı normal yayını kesip TA (announcement) geçebiliyor. Bizde ise RTÜK'ün umurunda değil. Hatta RDS'i bile autoswitch özelliği varken kasaba radyoları korsan olarak başka ana radyo kanallarının (mesela NTV vs) RDS numaralarını kopyalayarak kanal çalıyorlar. Bir bakıyorsun porsuk fm çalıyor. A Guide to the Radio Data System What is RDS? RDS, or the Radio Data System, is a system by which useful information can be transmitted to a tuner or receiver. Any radio that has the RDS "figure of eight" logo and wording will be able to receive and decode RDS information. Information available will often include: the station name an indication as to whether the station broadcasts travel bulletins an outline of the programme currently being broadcast the current time RDS works on the FM waveband only since the RDS information is encoded within the FM signal. RDS is not available on medium wave, long wave or the AM waveband. Programme Service (PS) This is the name of the station currently tuned to (known as the Programme Service or PS). For example, if you were listening to Radio 2 on a suitably-equipped radio, the frequency in the display would be replaced by _BBC_R2_. If Classic FM were tuned in, the display would switch from the frequency to CLASSIC_. The Programme Service name is limited to eight characters. Some radios, though not all, will store the name (PS) in memory when the station is added as a preset on the radio. Alternative Frequency (AF) Within the data sent to an RDS radio will be information about which other frequencies the station can be heard on. An RDS radio will retune to a different frequency when the current signal becomes too weak, assuming an alternative frequency is available for the station. For this to happen, the AF function must be switched on. Sometimes the radio will keep trying to find a stronger signal for the station. This can become distracting as the radio retunes itself, but can be overcome by switching the AF function off. In theory, if travelling around the country, it should be possible to listen to all the national stations via a car radio without having to manually retune. Some home tuners do not have the Alternative Frequency feature. RDS Search Some tuners will allow you to search for stations which use RDS. Since most stations on FM use RDS anyway, this feature is of limited value. Traffic Programme (TP) and Traffic Announcement (TA) The radio display can show if the station broadcasts travel information. Since most stations do anyway, this feature by itself is of limited value. The Traffic Announcement (TA) feature allows interruption of a CD or cassette tape when there is a travel report from the radio station that is currently tuned-in. The radio will automatically switch from CD or tape to the radio for the duration of the travel announcement. Commercial radio stations will broadcast three tones or 'bleeps' before and after the travel bulletin, but BBC radio stations do not need this. These DTMF tones are used when the transmitter (where the RDS inserter physically is) is located remotely from the studio, and for reasons of cost or practicality there is no control path from the studio to the transmitter to tell the transmitter when to switch on the TA flag. The only link from studio to transmitter is the station audio itself. In these situations, "in-band signalling" is used. A unit at the transmitter site listens out for the DTMF tones in order to switch the TA flag on and off. The DTMF tones are recorded on the traffic jingles to make life easier for the presenter. For the TA feature to work under any circumstances, however, the function marked TA, TI, TP or 'Traffic' must be switched on. It is possible to search out only those stations broadcasting the Traffic Programme on some radios. Enhanced Other Networks (EON) Most RDS tuners are now fitted with the EON facility, which offers the ability for local stations to 'break into' a national station's broadcast for the duration of a Traffic Announcement. When listening to a BBC national station, such as BBC Radio 3, EON will tell the radio about any traffic bulletins being broadcast by BBC stations in the local area. The radio would switch to the local BBC radio station for the travel bulletin, then back to the national station when the bulletin had finished. For example, when travelling through Oxford whilst BBC Radio 2 is tuned-in, the radio will switch to BBC Radio Oxford for any travel bulletins, with the TA function switched on. This feature is not usually implemented on commercial radio stations, such as Classic FM. While a proportion of the RDS datastream is used to provide programme and contact information for Classic FM, a small amount is classed as an "Additional Services Licence". This spare capacity on the RDS is used by Itis Holdings to provide a RDS-TMC (Radio Data System-Traffic Message Channel) service, using Classic FM's RDS. Cars fitted with the necessary electronics are able to decode this information and it is used to provide navigational and traffic information. The EON feature will work even if a cassette or CD is being played; the CD or tape will be interrupted by a local or national travel bulletin if 'EON' is lit in the radio's display. Programme Type (PTY) Radio stations can assign different programme types to their shows, depending on what is being broadcast at a particular time of day. These can be picked up by an RDS radio. The listener can use the radio to search for a particular type of programme. The radio will then scan the dial to look for the programme type selected. If one is found, the radio will tune in to the station. There are several Programme Types. These include NEWS, CURRENT AFFAIRS, INFO(information), SPORT, EDUCATION, DRAMA, CULTURE, SCIENCE, POP MUSIC, ROCK MUSIC, MOR(middle of the road), LIGHT MUSIC(light classical music), OTHER MUSIC, CLASSICS(more 'serious' classical music) and VARIED (speech and/or music). For example, Bristol's Star 107.2 sets its programme type (PTY) to VARIED all the time. However, Radio 4 might set its PTY to AFFAIRS when it's broadcasting a programme about current affairs, but switch the programme type to NEWS at 6:00pm for the news bulletin. The PTY can be set, with the radio remaining tuned in to the current station, until a particular programme becomes available. For example, if the PTY is set to NEWS, the radio will wait until a NEWS programme becomes available before tuning in to the station broadcasting news. When the news has finished, the previous station will be tuned back in. It is therefore possible to listen to Radio 1 whilst being able to catch the news on Radio 2 using the PTY NEWS selection. For this to work, PTY must be switched on. RadioTEXT (RT) Most RDS radios can receive short messages which might include information about the presenter, station or programme you are listening to. For example, BBC Radio 1's RadioTEXT always gives information about the presenter and programme e.g. JOHN PEEL - TONIGHT IN SESSION.. ETC.., whereas Classic FM gives information which includes a web address for the station, e.g. CLASSIC FM ON THE WEB - WWW.CLASSICFM.COM. The information will usually scroll across the display on a home tuner, but this could be distracting to a driver in a car, so the RadioTEXT message in a car hi-fi does not scroll. Clock Time (CT) Some stations broadcast the time and date within the encoded RDS signal. Usually, the time of day is just displayed. The time signal is automatically adjusted for British Summer Time. Most local radio stations do not bother with the RDS Clock Time feature.

Mehmet Göktürk 12 Ocak 2017 Yazar Paylaş 12 Ocak 2017 Hayır RDS genel birçok konunun birleşimi. RDS'in önemli özelliklerinden birisi STATION ID. Yani istasyonun RTÜK tarafından verilen numarasını yayınlayabiliyor ve arka planda tuner sürekli olarak diğer kanalları tarıyor. Eğer aynı ID'nin daha güçlü bir vericisini yakalarsa alıcı otomatik olarak ona geçiyor. Böylece uzun yolculuklarda kesintisiz olarak dinleme olanaüı sunuluyor. Bizde ise RTÜK bu ID sayısını takip etmiyor. TRT vericileri kuruluşlarında bazıları düzgün yapmışlardı. Örneğin istanbuldan izmit'e giderken TRT3 dinliyordum. Gebzeye gelince kocaeli vericisine otomatik geçiş yapıyordu. Daha sonra kocaeli vericisini TRT-FM verecek şekilde planladılar. İstanbuldan Radyo3 dinleyerek gelirken gebzede aniden TRTFMe geçmeye başladı. İlgili mühendise yöneticiye taksimdeki binada ulaştım. Bana haklısın dedi unutmuşlar ID yi düzeltmeyi. Ancak kocaelideki arkdaşlar onu yapacak kapasitede değil ben gittiğim zaman düzeltirim sağolun haber verdiğiniz için dedi. Gebzenin cart curt kanalları mesela önemli kanalların (NTV de oluyor çoğu zaman) ID lerini kullanıyor. Normalde cezası olması lazım. Gebzeye gelince bir anda NTV sandığın radyo şıkıdım havasına dönüşüveriyor. Umarım anlatabildim. NOT: Yukarıdaki ingilizce açıklamadaki ALTERNATIVE FREQUENCY (AF) özelliği olarak açıklanmış resmi adı AF. yazı gösteren bölümü sadece radio text RT özelliği. 1 Yorum bağlantısı
