Definitions

  • the invention relates to a method of transmitting radio data system (RDS) signals to accompany a transmitted programme in groups of an extended other network (EON) type, the method comprising providing an RDS signal having first to fourth blocks, inserting a programme identification code of said programme in said first block, inserting a programme identification code in said fourth block, each of said programme identification codes comprising a country code, an area coverage code and a programme reference code, inserting in said third block one of a series of information items which pertain to the programme which is identified in the fourth block, and inserting in said second block a code identifying the extended other network type as well as a multiple-variant usage code identifying which of said series of information items is carried in the third block, as well as to a receiver for use in conjunction with transmissions of the radio data system (RDS) signals according to this method.
  • RDS radio data system
  • the radio data system RDS provides the possibility to transmit reliably digital information related not only to the actually received programme, i.e. the programme of the tuned network, identified with programme identification code PI(TN), but also to programmes of socalled other networks, identified with programme identification code PI(ON).
  • PI(TN) programme identification code
  • PI(ON) programme identification code
  • forms A and B of a socalled type 14 or EON group are specified in said Proposed Supplement 4.
  • type 14 or EON group refers to form A, which is the normal form of this group, as form B is not relevant to the present invention.
  • the specified EON group consists of first to fourth blocks, each block comprising a 16 bit information word.
  • the first and fourth blocks carry respectively the abovementioned PI(TN) and PI(ON) codes.
  • the second block comprises amongst other codes, a code (GT) identifying the EON group type and a 4-bit usage code (UC) specifying the contents of the third block.
  • This third block carries data pertaining to the programme which is identified in the fourth block. This data may relate to e.g. its programme service name PS(ON) identified by UC variants 0000 to 0011, alternative frequencies AF(ON) identified by UC variant 0100, or mapped frequencies identified by UC variant 0101, etc.
  • the EON groups provide the possibility at the receiver's side to monitor other network (ON) programmes and to bluild up banks of information, e.g. the AF(ON) bits of such ON programmes, while being tuned to the transmitted or tuned network (TN) programme.
  • AF(ON) lists has the advantage that when two or more programmes are mutually linked, i.e. when these programmes have a mutually identical audio programme signal, a search for an optimum tuning frequency can be executed within the total set of alternative frequencies occurring in the AF lists of all mutually linked programmes.
  • various programme linking patterns are used as many countries use various combinations of regional transmitter chains at certain times to transmit a common programme. For example, in a country with regions A, B, and C, the broadcaster may use A and C in conjunction at one time in the day, and A and B together some time later. Another example is the frequent case where a local radio station transmits a national programme at night.
  • Another object of the invention is to provide a coding method for coding RDS programme linking information such that on the one hand items of the coded information can be sent within a part of each EON group and applied at the receiver's side independent from the data carried in other EON groups and on the other hand great flexibility as to the number and the choice of the linked programmes is achieved.
  • the invention provides a method of transmitting radio data system (RDS) signals to accompany a transmitted programme in groups of an extended other network (EON) type, the method comprising providing an RDS signal having first to fourth blocks, inserting a programme identification code of said programme in said first block, inserting a programme identification code in said fourth block, each of said programme identification codes comprising a country code, an area coverage code and a programme reference code, inserting in said third block one of a series of information items which pertain to the programme which is identified in the fourth block, and inserting in said second block a code identifying the extended other network type as well as a multiple-variant usage code identifying which of said series of information items is carried in the third block, and in which the second block has a usage code variant which identifies transmission of a linkage word as an information item in the third block, the linkage word in the third block carrying information related to the programme identification code of a programme or programmes to be linked to the programme identified in the fourth block.
  • RDS radio data system
  • EON extended other network
  • the invention also provides a radio data receiver for use in conjunction with transmission of radio data system signals comprising decoding means for decoding received groups of an extended other network (EON) type, processing means for processing the decoded data carried by said groups, and storage means comprising memory banks for storing therein bits identifying alternative frequencies, and in which the processing means are programmed to identify first to fourth blocks in the groups, to identify in the second block of an EON group the transmission of a usage code variant indicating the presence of a linkage word, to identify the linkage word in the third block, to derive from the linkage word a programme identification code of a programme or programmes to be linked to a programme identified in the fourth block, to allocate a memory bank to the programme identification code of each of said programmes, and to store therein alternative frequencies pertaining thereto.
  • EON extended other network
  • the programme identification codes of the programmes to be mutually linked are derivable from the linkage word and from the fourth block and do not change when these programmes are actually linked together.
  • a memory bank for storing a list of AF's is allocated to each of said programme idencification codes.
  • the linkage word occupies only one block of one out of 16 variants of the EON group therewith hardly reducing the transmission capacity of EON groups.
  • the transmission rate of the EON groups is sufficiently high to guarantee at the receiver's side an adequately fast acquisition of the AF's of the programmes to be mutually linked.
  • An actual link between two or more programmes authorizes the receiver to search for an optimum tuning frequency within the total set of AF's of all linked programmes, without losing the individual identity of the programmes. It is therefore possible to return the receivers's tuning to the original programme after unlinking.
  • a method according to the invention is preferably characterized in that the linkage word comprises a link classification word and a link identification word, the link classification word carrying data related to at least one of the area coverage and the programme reference codes of the programme or programmes to be linked to the programme identified in the fourth block, said data being coded according to one of several classes of linkage coding scheme, the link classification word identifying said one class of linkage coding scheme.
  • This measure is based on the recognition that the programme linking patterns occurring in practice may be classified is several classes of link, each class being identified by a particular variant of the link classification word.
  • a radio data receiver for use in conjunction with transmissions of RDS signals according to this method is characterized in that the processing means are programmed to identify from the link classification word the linkage coding scheme applied to the link identification word and to identify on the basis of this linkage coding scheme from the link identification word at least one of the area coverage and programme reference codes and from the country code of the programme identified in the fourth block the country code of the programme identification code of the programme or programmes for allocating a memory bank thereto.

  • RDS radio data system
  • EON extended other network
  • Figure 1 shows the format of a type 14 or Enhanced Other Network group for executing the method according to the invention, which differs from that defined in the above Proposed Supplement 4 merely in the new use of usage code (UC) variant 12 (1100).
  • UC usage code
  • Figure 2 shows the format of the EON group (type 14-A form) with UC variant 12 in block 2, carrying a 16-bit data structure in block 3, called the linkage word.
  • This word defines the set of PI codes that the programme service is to be considered to be linked with.
  • the form of the word can be defined as follows:-
  • a link is considered to be cleared if the relevant linkage bits (11..0 in Generic and Specific, 7..0 in General) are all set to zero.
  • the country code of any linked services is always derived from the EON PI code under which this linkage word is to be loaded.
  • Bit 15 of the linkage word is used to indicate whether the defined link is in effect at the present moment. This bit should be set at the moment that the programme services link together and cleared before the programmes resume their individual identity.
  • the cleared condition may be used by a receiver to initiate storage of EON information about possible linked services in advance.
  • D201 is linked (using the general linkage word) to all generic variants of Dn25 (forward linking).
  • the receiver will then begin to load information pertaining to these PI codes. This could result in D525, D625 and D725 being loaded.
  • An individual link between any one of these services and D201 is considered to be potentially in effect if a linkage word back to D201 is detected in the EON information about the respective service.
  • D201 is actively linked to D525 and D725, but not to D625.
  • Figures 3 and 4 show by way of example the contents of the memory banks of an RDS receiver in the case of generic or regional links, and specific links, respectively.
  • the memory banks in which preset PI's can be stored can be activated by the user through buttons 1-6.
  • the memory banks indicated with pool stores also called background memories are activated by a microprocessor of the receiver, which can be programmed to store the PI, TP/mapped frequency, AF information at the reception of the ION information of ON programs with a certain relationship with the programs of the preset memory banks as shown in Figures 3 and 4.

  • Figure 6 shows geographically the area's of 2 networks with PI codes C201 and C525 respectively.
  • FIG 7 shows a flow chart of a process in an RDS receiver for determining from EON information which programs can be expected to be linked.
  • the PI code of the tuned programme e.g. PI1 is selected and stored.
  • a detection of the presence of EON groups occurs. If no EON groups are present in the received RDS signal, then the process returns to the beginning of this block 2. If such EON groups are received then in block 3 these EON groups are detected on the occurrence of a linkage word LW (UC variant 12), this LW being also selected in block 3. If not LW is present in the received EON group then through Q in block 16 (figure 8) the received EON data is stored in the preset and/or pool stores as e.g. shown in figures 3 and 4.
  • LW linkage word
  • the selected LW is detected on the presence of a potential link. If there is a potential link then the EON data and the linkage actuator (LA) are monitored through P in block 15, which will be described later. If not then in block 5 is determined whether the LW relates to PI1.
  • Block A determines which PI code may be expected to be linked to PI1, e.g. PI code PI2 (forward linking).
  • Block A therefore comprises block 6, which asks whether the program to be linked is known. If this program is not known, identification of this program occurs in block 7. If this program is known then a flag L1 is set in block 8.
  • Block 9 is determined whether LW refers to PI2. If LW does not refer to PI2, then the process returns to block 2. If LW refers to PI2 then in block B is determined whether PI2 may be expected to be linked to PI1 (backward linking). Block B therefore comprises block 10, in which the question has to be answered whether the program to be linked is known. If said program is not known then identification thereof occurs in block 12. If on the contrary the program is known, than a flag L2 is set in block 12.
  • block 14 is determined whether the flag L1 and L2 are both set. If so then the process confirms that a potential link between PI1 and PI2 is present. If not then the process return to block 2.
  • Figure 8 shows a flow chart of a process for utilizing the result of the process of figure 7, having blocks 1-3 in common with the flow chart of said figure 7.
  • Block 15 the LA in the LW is monitored for PI1 as well as for PI2. If both LA's are set to "one" then in block C the AF-lists of PI1 and PI2 (AF1 and AF2 respectively) are combined into one AF-list (AF1 + AF2), so that the receiver can search for the optimal AF in each of the two AF-lists.
  • Block C therefore comprises a block 17, in which is determined whether the link is active. If the link is not active then no linking occurs and an eventual search for optimal AF is restricted to the AF-lists of PI1. If the link is active, then the AF-lists of PI1 and PI2 are combined as beforementioned and the process returns through R to the beginning of the flow chart in figure 7.
  • bits 1 to 4 of the linkage word are used to give information regarding the status of the link, the class of link and the extended-generic flag (EG).
  • the extended-generic indicator is set to inform the receiver that the programme service, defined in block 4, is a member of an extended-generic set.
  • a set of services is characterized by PI codes of the form WXYZ, where W is the common country code, X is the area code (and must lie in the range R1 to R12), Y is common to all such related services, and Z may assume any value. This permits a generically related set of services to comprise more than twelve members, each with a unique PI code.
  • the linkage actuator (LA) is set to 1 to inform the receiver that the link is in effect at the present moment. If the bit is set to zero, a potential link is indicated, and the receiver may use the linkage data to determine those services about which EON data should be acquired.
