    TRDS4002 4. General Description 4.1 Overview of the RDS service There is a growing, global interest, both on the part of industry, as well as broadcasters, in information systems which utilize a data channel inserted into radiophonic transmissions. The interest in these new systems has been stimulated by the continuing evolution of...
  • Page 8 TRDS4002 Radiodata is the fruit of work undertaken by a specialized UER group, based on five proposals formulated by Sweden, The Netherlands, Great Britain, Finland and France. The superiority of this system results mainly from its protection from transmission errors, crucial for in-car reception, high speed to synchronize the data groups, from its high data rate, its potential for new applications and flexibility of use.
  • Page 9 TRDS4002 Figure 2 To avoid phase ambiguity on recovering the 57 KHz subcarrier, in the case of coherent demodulation, the binary data signal undergoes differential encoding prior to biphase encoding. Fig.3 gives an example of the 57 KHz subcarrier after modulation by the data signal.

  • Page 11 TRDS4002 Fig.5 shows the protection ratio curves for the three services. Figure 5 The structure of the data signal is shown in fig.5. Base-band structure of Radiodata The structural element is the “group” containing 104 bits. Each group comprises 4 blocks of 26 bits each, of which 16 are information and 10 are for protection.

    TRDS4002 There is a choice, therefore, between simple error detection which will not recover the message and full error correction which will do so. From the results of reception tests carried out in Sweden, it would seem that the optimum decoding strategy, both for domestic as well as in-car reception, requires correction of single errors and adjacent double errors and the detection of long error strings.

    TRDS4002 For example, it will be possible to transmit a commentary to the main program, as a RADIOTEXT message comprising text made up of alphanumeric characters (ASCII) that will appear on a display integrated into the receiver, and ultimately be able to control a voice synthesizer.
  • Page 14 TRDS4002 The car radio, as well as being tuned to the station transmitting traffic announcements, has to be enabled to receive ARI INFO or TA. Once the announcement has been made, the radio automatically reverts to cassette listening. This function is analogous to ARI.

  • Page 16 TRDS4002 This service, which is similar to Radiotext, allows serial alphanumeric information, corresponding to computer software or other non displayable information, to be transmitted. Clock Time (CT) As per CCIR standards, information relating to time and date is defined by Coordinated Universal Time (UTC) and by Modified Julian Day (MJD).

    TRDS4002 A special device is required to maintain the normal signal. This device will insert the RDS signal to every individual transmitter. Such a device is the RDS MIXER MKII. 5.3 Interconnection The RDS data encoder must be connected between the stereo encoder and the transmitter.
  • Page 19 TRDS4002 To install the program, go to the CDROM reader drive, and double click on the Setup.exe icon. The program will be automatically installed and a link will be created on the program bar. To execute the program, click on the Start button on the applications bar with the left button of the mouse.
  • Page 20 TRDS4002 Select the RS232 icon and the following window will appear: Let’s now see the parameters and their meaning: - RSD Option This is used to choose whether a coder programmed locally or via satellite is involved. This choice affects all the programming windows and disables or enables certain functions.
  • Page 21 TRDS4002 searches the communication parameters of the serial port. It may in any event always be entered manually. - Serial Port Choice of the communication port: COM1, COM2, COM3 or COM4. - Baudrate Choice of the transmission speed. It must be set according to all set on the dipswitches of the coder.
  • Page 22 TRDS4002 Let’s see the parameters and their meaning. A box at the left hand part is displayed where the coder address is entered. The default address is ?????. The Send Address push button at the side of this text box is used to activate the coder for programming, whether this is done “locally”...
  • Page 23 TRDS4002 Up to 50 PSN’s can be programmed. Programming is quite simple. Enter the Time (sec) (transmission time in seconds) of each PSN (it is advisable to enter a time of less than 3 sec). Edit the PSN, which may have a length of 8 characters, including spaces.
  • Page 24 TRDS4002 Let’s examine the programming of the Radio Text. As described earlier, click on the board Radio Text tab. The following window will be displayed. Following the same programming procedure as that for the PSN, enter the transmission Time (sec) of the string of characters then, in the Radio Text box, enter the text of up to 64 characters.
  • Page 25 TRDS4002 Enter the date of the Day when the programming is to be made. Enter the programming beginning Time. Select the programming mode amongst those offered. Now, going on to a new setting, the 4-figure PIN code will automatically be created. The last box shows whether the setting has already been made (Yes) or whether it is still to be processed (No).

For example: we want to broadcast page 7 at 10:30 on the 14th June 2000. In this case, as it is the first setting, select the Plan Nr.000 line, enter 10.30 in the Time box, then 14-06-2000 in the Date box and then in the PSN page, enter the page bearing our setting 7 and finally enable the setting, Enable On.
  • Page 30 TRDS4002 In a very simple manner, the date and time can be assigned. The CT OFFSET function is used to enter the time zone difference, (this function is normally used in America). The DATE PSN function is used to decide in which PSN the date must appear.
