Definitions
- the invention is based on a method for sending digital broadcast signals according to the genre of the independent Claim.
- DAB Digital Audio Broadcasting
- a program channel that is known as an ensemble, at DAB in one Single-wave network broadcast. This means that all stations broadcast on the same frequency, the same broadcast signals. A There is no interference between them. So that can the ensemble nationwide on one and the same frequency be received.
- the audio data is marked with a MPEG encoder source-coded. The subjectively heard quality The MPEG encoding depends on the amount of one generated data rate from and on the other from the type of Audio input signal. Classic needs a high one Data rate, simple speech can be heard without Loss of quality encoded at a very low rate become.
- the MPEG encoder is currently fixed at DAB set so that e.g. as a fixed output Bit stream of 168 kilobytes / sec. for an audio channel.
- the invention is therefore based on the object Process for sending digital broadcast signals too create it within a single frequency network enables, regionally limited radio programs radiate.
- the Problem zone is solved, i.e. in the Transition areas between the transmission zones of two transmitters are regional programs of these two Receivable stations, provided both stations are on different regional program on the same frequency broadcast in the same subchannel. Now overlap different regional radio programs, it is for a receiver is not possible in this interference zone decode regional broadcast program correctly. Therefore then the radio receiver is on the same time switch nationally broadcast radio program and play this acoustically. However, are both transmitters wired in such a way that they are the same regional Broadcast radio program, then it is in this too Transition zone possible for the radio receiver, the regional broadcast radio program to decode.
- a regional Broadcasting program is transmitted, in a frame, in to which the broadcast signals are transmitted in one specified data field is displayed.
- DAB is for that for example the Fast Information Channel (FIC) is available.
- FIC Fast Information Channel
- Broadcasters also want digital Broadcasting method, such as DAB is to broadcast regional radio programs.
- DAB digital Broadcasting method
- SWR Spadwestrundfunk
- the available data rate is therefore according to the invention to a national broadcasting program and a regional one Broadcasting program in a station in a particular Split time window. This becomes temporary for such Window carried out in, for example, local Messages are transmitted. Will be used both in the national as well as playing the same music in the regional can the full data rate can be used for the music.
- FIG. 1 is a block diagram of an inventive Transmitter shown.
- a data source 1 is connected to one Data input of a modulator 2 connected.
- the modulator 2 is then to an input of an OFDM modulator 3 connected.
- the OFDM modulator 3 is above its Data output connected to an amplifier 4.
- To the Amplifier 4 is connected to an antenna 5 at the output.
- the data source 1 provides the data to be transmitted.
- the data source 1 can be connected via a communication network a central office, for example a broadcast studio from which the data to be transferred come.
- This Communication network can be via satellite or wired or be realized via another radio connection.
- the Data is then transmitted to the modulator 2, which according to modulates the data, especially here a QPSK (quadrature phase shift keying), i.e. there will be here four different angles for encoding the data used.
- QPSK quadratture phase shift keying
- This then becomes the output of the modulator 2 Modulation symbols that the OFDM modulator 3 on closely adjacent carriers distributed. Because the carrier this process is called orthogonal to each other orthogonal frequency division multiplexing (OFDM).
- OFDM modulator 3 the OFDM signals are then on a transmission frequency implemented.
- the OFDM signals are then a digital / analog converter fed to the amplifier 4 to amplify and send the antenna 5.
- Data source 1 includes a source encoder, which is now if a regional radio program occurs in the decoding rate to a certain time window national broadcasting program and the regional Broadcasting program divides. This is only for a specific one Time, i.e. a time window, for example if regional and parallel national news be transmitted.
- FIG 2 is a block diagram of an inventive Broadcast receiver shown.
- An antenna 6 is a Radio frequency receiver 7 connected.
- the High-frequency receiver 7 is digital Processing unit 8 connected.
- the output of the digital Processing unit 8 is connected to an audio amplifier 9 connected.
- the audio amplifier 9 operates one Speaker 10.
- the radio receiver receives the with its antenna 6 broadcast signals and amplifies, filters and sets it into an intermediate frequency in the high-frequency receiver 7.
- the high-frequency receiver 7 also carries out an analog / digital conversion by.
- the resulting data stream is then from the digital processing unit 8, which is also a Processor can be processed. In doing so Channel decoding, demodulation and source coding carried out.
- the digital Processing unit 8 detects whether in addition to the national Broadcasting program also a regional broadcasting program is transmitted.
- the digital Processing unit 8 through the source decoding, since yes for the parallel transmission of regional and national radio programs a different Data rate used for these individual broadcast programs will when they are for the transfer of a sole national broadcasting program is used.
- the so decoded radio programs are then sent to the Audio amplifier 9 passed the audio signals amplified and reproduced with the speaker 10.
- FIG 3 is a flow chart of the invention Procedure shown that runs in the transmitter.
- Method step 11 becomes a regional one Broadcasting program in addition to the national broadcasting program to be broadcast, the data rate on the regional Broadcasting program and the national broadcasting program divided up.
- process step 12 these two the regional and national radio program, in put together in a time division multiplex to then in Method step 13 as digital radio signals to ship.
- a frame structure is used for of either alternating regional radio audio data and supra-regional radio audio data are transmitted. It is a different division of the different ones Broadcast data possible.
- Figure 4 is a flow chart shown that describes the method according to the invention, that happens in the receiver.
- the digital broadcast signals receive.
- the digital processing unit is now checking based on the data received, whether it is displayed in the FIC whether a regional radio program is being broadcast or not. If this is not the case, then in Method step 16 decodes the national program. However, if a regional radio program is broadcast, then is checked in step 17 whether the quality of the regional radio program is fine, so it will for example, the bit error rate is determined. Is that Bit error rate is below a certain threshold a high transmission quality before, then in Method step 18 the regional radio program decoded. If the bit error rate is too high, then in Method step 16 the national radio program decoded. This is followed by the audio amplification and the Play with the speaker.
- FIG. 5a shows the division of the data rate into one regional window shown schematically.
- the data rate is plotted and the time on the abscissa.
- a part of Data rate stands for example for the transmission of Multimedia data, i.e. graphic or text data available.
- Figure 5b shows a schematic transmitter illumination during the broadcasting of the regional radio program.
- Zone 1 will be the first regional radio program broadcast in Zone 2 and in Zone 3 a third regional radio program.
- zone 1 and 2 and between zones 2 and 3 there are interference zones.
- the data of the regional radio program from zone 1 and from the zone 2 or up to Zone 2 and Zone 3. This is reception from the regional radio program in each of the interference zones not possible. Therefore, then in the radio receiver on the Decoding and playback of the supraregional Broadcasting program switched. Then that is the Problem zone problem solved.
