Definitions
- the invention is based on a receiver for analog and digitally broadcast programs according to the genus of independent claim.
- the sections of a frame when receiving digitally transmitted broadcast signals used in which no information for the current set radio program are included then in analog and / or digital equivalent to these sections Check radio programs for their signal quality. This ensures that the check is not audible Effects leads so that the user through this measurement is not irritated.
- This has the advantage that the loss of a frame leads to hardly audible effects, because the audio information of a broadcast program is on many Frame is distributed and the loss of a frame means Error correction method can be compensated.
- the signal field strength of equivalent radio programs is measured to decide whether to switch to a equivalent radio program is possible.
- the Signal field strength is a meaningful signal parameter, that can be measured easily.
- Another advantage is that as additional signal parameters in the case of digitally transmitted radio programs Baseband energy, the results of one Attempting to synchronize, the signal field strength of Adjacent channels and the bit error rate are measured in order based on these different signal parameters meaningful picture about the quality of equivalents To win broadcasting programs.
- the different signal parameters for an equivalent Broadcast program can be measured, weighted and summed up and then compared to thresholds to decide whether to switch to this equivalent Broadcasting program is possible. This avoids that a wrong one by measuring only one signal parameter Impression of the signal quality of an equivalent Broadcasting program arises.
- the threshold values either loaded from memory, then it are specified and / or are processed by the processor of the Recipient calculated or at least recalculated to a situation such as generally bad Reception conditions to respond.
- FIG. 1 shows an inventive Receiver for analog and digitally transmitted Broadcast signals
- Figure 2 is a DAB frame
- Figure 3 is a RDS group.
- Radio receivers especially for those in Motor vehicles that are both transmitted analog Broadcast programs as well as digitally transmitted Can receive radio programs. Important criteria for Such a recipient are the lowest possible price and the smallest possible construction volume.
- DAB Digital Audio Broadcasting
- DAB broadcast radio program an automatic Switching to an equivalent radio program necessary to the driver of a manual search for a new one To relieve broadcasting program.
- radio programs that use other digital transmission methods such as DVB (Digital Video Broadcasting), DRM (Digital Radio Music) or ATSC (Advanced Television Systems Committee) or at least it is planned to use radio programs to transmit this digital transmission method.
- DVB Digital Video Broadcasting
- DRM Digital Radio Mondial
- ATSC Advanced Television Systems Committee
- this object is achieved in that a Receiver for digitally and analogue transmitted Broadcast programs in a short period of time a measurement of Signal parameters of equivalent radio programs performed without audible effects.
- FIG. 1 An antenna 1 is with a radio frequency receiving part 2 connected. Digital and received by antenna 1 analog broadcast signals are from the High-frequency receiving part 2 filtered, amplified and in one Intermediate frequency implemented.
- the high-frequency receiving part 2 is via an input / output connected to a processor 3.
- the processor 3 receives from the radio frequency receiving part 2 to one Intermediate frequency converted signals to them first digitize, decode, digital DAB / FM signal processing perform and then to one to the Processor 3 connected via a first data output Handover audio processing 4.
- the processor 3 sends the High frequency receiving part 2 data, which frequencies and so which radio programs from the spectrum are to be filtered out.
- the audio processing 4 is over one first output connected to a loudspeaker 5.
- the Processor 3 is connected to a via a second data output Display 13 connected.
- the audio processing 4 prepares the digital data for the acoustic representation by means of the loudspeaker 5.
- the Processor 3 prepares the digital data for an optical one Presentation before if not only in the received data Audio data, but also data that is included are also to be represented by means of the display 13.
- the Display 13 is a screen, but also others Projection techniques are possible.
- Antenna 1 transmits both analog and also receive digitally transmitted radio signals.
- FM has from analog broadcast programs the best Signal quality. However, it is also medium wave and Shortwave possible. RDS can have different dates, so e.g. Information on frequencies on which equivalents Broadcast programs are transmitted.
- Equivalent radio programs here either denote the same radio programs that are on different frequencies be transferred and / or by means of another Transmission process, i.e. digital instead of analog or analog instead of digital.
- the equivalent Broadcasting programs also refer to programs that a similar content to that currently set Show radio program. Here, e.g. on News broadcaster with another news broadcaster replaced. This program information, what kind of Information or music in a particular Broadcasting programs are broadcast at digital broadcast radio programs in co-transmitted data included and RDS is also used for FM.
- DAB digital audio Broadcasting
- DAB digital audio Broadcasting
- the signal to be transmitted is used on many different frequencies distributed to the effects of a frequency-selective attenuation to the received signal minimize. Because by distributing the signal different frequencies will only make up a small percentage of the transmitted signal by a frequency selective Damping disturbed. This disorder can then be corrected Error detection and correction procedures corrected become.
- Processes related to DAB are DVB (Digital Video Broadcasting) and DRM (Digital Radio Mondial). This Methods differ from DAB in particular in the Transmission frequencies, the transmission rate and the exact Frame structure. However, these procedures are also for the Device according to the invention can be used. ATSC points out Signals only at one frequency.
- the receiver according to the invention receives a digital broadcast radio program, the receiver performs for short Periods of measurement of signal parameters from Broadcast signals from equivalent broadcast programs. The time intervals between measurements can be considerable be longer.
- Broadcast programs always have priority over analogue broadcasts
- Broadcasting programs given as digitally transmitted Broadcast programs have a clearly better signal-to-noise ratio and still attractive opportunities for multimedia applications have that in analog transmitted Broadcast programs only to a very limited extent possible are.
- the procedure is such that if a change from the current broadcast program necessary due to deteriorating signal parameters is, initially according to the same radio program on a other frequency is sought, with digital and then analog broadcast programs are examined. If this search does not lead to success, then will Radio programs with equivalent content, again digital broadcast programs and then examined analog broadcast programs become.
- the signal parameters of all equivalents are digital broadcast radio programs and also the signal parameters of the digital broadcast program currently received at this first threshold, then it becomes equivalent transmitted analog radio program switched, if the signal parameters of this transmitted analog Broadcast program are above a second threshold. Are the signal parameters of this analog transmitted Broadcast program below the second threshold, then indicated by the display 13 that no reception possible is.
- the threshold values are sent to the processor 3 connected memory loaded, these threshold values then be determined in advance based on experimental investigations regarding audio quality who receive radio programs. In a further education of Invention is provided that these threshold values from the Processor 3 based on the loaded threshold values are calculated to respond to changing reception conditions respond so that an adaptation to this Reception conditions exist.
- the processor 3 based on stored mathematical models and the current reception conditions the threshold values continuously new be calculated.
- a DAB frame is shown in FIG.
- field 6 of the DAB framework are synchronization signals and information about included the frame structure.
- box 7 of the DAB framework are Data for a radio program A contained in a field 8 Data for a radio program B and in a field 9 data for a radio program C. This is currently set Broadcasting program B. This can be during sections 7 and 9, which contain data currently set for the Broadcasting programs are not necessary to take measurements from that Broadcasting program B equivalent broadcasting programs be performed. This results in no audible Effects for the user of the radio receiver occur since the duration of sections 7 and 9 anyway for the Representation of the radio program B are irrelevant.
- FM signals are interrupted for a very short time of reception, which is used for the measurement of signal parameters of equivalent radio programs is necessary to none audible effects for the user of the receiver. Such a brief interruption has a duration of, for example 5 ms.
- a list of the frequencies of equivalent broadcast programs instead of one List of equivalent radio programs is to be transmitted it is also possible to have a list of all broadcast programs, which can be received to transmit to the To let the recipient evaluate the nature of the respective radio programs are.
- DAB there is one Program type identifier is provided and is at RDS Program information code. For radio programs that are transmitted analogously and which are not digital carriers must be specified in a list, which type of music and information on this radio program be broadcast.
- An RDS group is shown in FIG.
- box 10 is a program identification is given, in field 11 one Error detection and in field 12 are more information contain.
- the program information in field 10 can be used Determination of what type the transmitted Broadcasting program is.
- the signal field strength is particularly suitable. It indicates how strong a radio program is received.
- digital Broadcast signals are the other signal parameters Baseband energy and / or results one Attempting to synchronize or the signal field strength of a Adjacent channel to use.
- the signal field strength of a Adjacent channel denotes another's crosstalk Transmitter that is not necessarily a radio broadcaster. Nevertheless, this transmitter can, if only a small one Has frequency distance to a radio program, a cause significant interference and thus the signal quality of the radio program decisively affect.
- a signal-to-noise ratio and / or a deviation of the the frequency specified in the RDS or DAB signal is analog broadcast radio program or a channel estimate that indicates how the multipath propagation for this Broadcasting program presents itself and / or the Signal field strength of a neighboring signal and / or a Pilot tone detection and / or detection of a digital Carrier, which is preferably the RDS and / or the Determination of the frequency swing.
- the use of a symmetry detector is an advantage. If the symmetry detector detects an asymmetry, this is attributable to multipath propagation. This method is considerably less computationally intensive than a channel estimate.
- the symmetry detector determines, for example, from one Sum and difference signal for stereo transmissions balanced signal and recognizes whether there is an asymmetry is present.
- Das is the first threshold for digital broadcast signals and the second for analog broadcast signals Threshold.
- the results of the evaluation of the signal parameters with Threshold values are signaled, and the Signaling results are then shared compared, for example with a logical link.
- the individual signal parameters can also be weighted to be using the same thresholds too to compare.
