Definitions
- the present invention relates to quality assessment of data-reduced audio and / or voice signals and in particular to a method and an apparatus to trigger a measurement procedure for quality assessment of audio and / or voice signals.
- Modern procedures for quality assessment of data-reduced Audio and / or voice signals such as NMR, PAQM or POM signals, do not use any special synthetically generated measurement signals, but real audio and / or voice signals.
- the original Signal is e.g. one recorded in a recording studio Audio and / or voice signal that by means of a Cable connection or by means of a wireless radio link to be transmitted to a recipient. So that an economic Transmission is possible, this signal must data reduced or encoded, after which the same as Bitstream is supplied to a digital transmitter, e.g.
- Bitstream performs pulse amplitude quadrature modulation, whereby the data-reduced audio and / or speech signal, i.e. of the Bitstream, is modulated onto a carrier.
- This carrier is using a suitable antenna in the case of a wireless Radio transmission emitted and by means of a suitable Receiving antenna received and demodulated.
- Bitstream After demodulation the modulated by a suitable modulation method Bitstream is the same as that in the transmitter before Modulation of the existing bit stream apart from the influences of the Radio link similar.
- inverse coding or Decoding and after a digital / analog conversion can do that signal originally recorded in the recording studio be made audible.
- Procedure for quality assessment of data-reduced audio signals make differences of the audible in the receiver made audio signal with respect to the present Example recorded audio signal in the recording studio, either coding or decoding errors or due to the transmission link to detect introduced bit errors. It will a reference signal, i.e. the one recorded in the recording studio Signal, with a test signal, i.e. that is audible in the receiver signal made after the digital / analog conversion, compared, the quality of the coding, the radio link and to assess the decoding.
- the reference signal must be known to the Underlying test signal. Due to the fact that it is for the quality assessment is not required, the test signals to be constantly compared with the reference signal it assumes that the changes in the time of the Coding or decoding or the radio link possible, only a section of the test signal to which a reference signal to compare with the reference signal. Of course, this section of the test signal, the the reference signal is based, and the reference signal be present in the measuring device itself.
- Always recurring same audio signals from radio programs are e.g. Jingles which initiate certain radio programs and not be changed over long periods of time, as they Identification of a listener with "his" radio program contribute significantly. It is possible with one time Providing a jingle at the transmitter on many different Locations and at many different times quality measurements a received audio and / or voice signal perform.
- the object of the present invention is a exact triggering of a measuring procedure for quality assessment to create audio and / or voice signals.
- radio link 16 the coded and modulated audio and / or voice signal to be received by a receiving antenna 18.
- the radio link 16 is only exemplary, since the same is also by a Cable connection can be realized, which for example digital radio signals or digital television signals, i.e. Multimedia signals.
- Audio and / or voice signal is in a receiver 20 appropriately demodulated and decoded as well converted analog / digital and via a receiving line 22 a jingle detector 24 which supplies the device to trigger a measurement procedure for quality assessment represents audio and / or voice signals and via a Detector connection 26 connected to a measuring device 28 (Fig. 2) is one of a variety of ones known to those skilled in the art Measuring method for quality assessment of audio and / or can carry out speech signals.
- Dashed line from the connection of the audio source 10 and the transmitter 12 to the jingle detector 24 provides one Reference signal line 30.
- the broken line the reference signal line 30 should symbolize that this Connection between the audio source 10 and the jingle detector 24 no through connection needs to be there as it is a reference signal, i.e. the audio signal a jingle, just before coding and modulation once or at certain times to the jingle detector 24 must be supplied. Contrast it the solid connections at least during a measurement process for quality assessment of audio signals constantly active data connections.
- Fig. 2 shows a more detailed representation of the jingle detector 24, which in a preferred embodiment a personal computer with suitable software and with a suitable operating system.
- the jingle detector 24 has a storage device 242 for storing the Reference signal and for storing the test signal on that a digital signal processor card 244 via a test signal input 22 is supplied. Via a first exit 26a, the test signal can be fed to the measuring device if necessary while a second output 26b of the digital signal processor card 244 if necessary, the reference signal Meter 28 will feed.
- a communication line 26c serves for initialization tasks and for measuring communications between the jingle detector 24 and the measuring device 28. Die The fact that the communication line 26c is drawn in dashed lines is analogous to the reference signal line 30 of Fig. 1 shows that the communication line 26c is not continuously active, but only for example the beginning or end of a measurement by the measuring device 28 will signal.
- the reference signal based on appropriate way from the audio source 10 to the Jingle detector 24 was transferred to the memory device 242, which is a hard drive of a standard personal computer is recorded.
- the standard personal computer points the digital signal processor card as additional hardware 244 in the form of a plug-in card that accepts the audio test signal input 22 and the first output 26a and the second Output 26b has.
- the three lines 26a to 26c like it already out the reference numerals assigned to them can be seen in the Detector connection 26 of FIG. 1 are included.
- the test signal input 22 of the signal processor card 244, the several Signal processors can contain, as can be seen from Fig. 1 is suitably connected to the receiver 20. Of the first output 26a and the second output 26b of the digital Signal processor card 244 are with corresponding inputs of the measuring device 28 for the test signal or for the reference signal connected.
- the present invention is at the beginning of a measurement cycle a first section of the values of the reference signal from the Hard disk 242 in a memory of the digital signal processor card 244 read.
- This first section can be about 1.5 s long.
- This first section of the values of the reference signal is in the digital signal processor card 244 filtered, subsampled and then by means of a Cross-correlation with a section treated in the same way of the test signal, which is received via the digital line 22 Signal processor card 244 or the memory device 242 is compared.
- the test signal was also filtered and subsampled.
- the means for determining the degree of agreement of a section of the Values of the reference signal with the values of the test signal also in terms of hardware by means of suitable shift registers and Logic gates that are essentially an exclusive-OR operation be able to perform.
- the comparison takes place between a section of the values of the reference signal with a section of the values of the test signal to be assessed in sections instead of.
- One section consists of a preferred one Embodiment of the present invention 512 samples of the test signal, this section is also referred to as a "frame".
- the Section of the values of the reference signal made shorter, see above the comparison operation will run faster, however the number of incorrect recordings of the match increase between the test signal and the reference signal becomes. If the section of the values of the reference signal, which is used to determine a degree of match if you choose longer, the one for this operation increases time, but the probability decrease in incorrect registration of a match becomes.
- the measuring device 28 shares over communication line 26c the measuring device 28 with the start of the measurement, whereby the Measuring device 28 is activated to via the first output 26a of the jingle detector 24 a further section of the values to receive the reference signal, essentially simultaneously via the second output 26b of the jingle detector 24 the measuring device the corresponding values of the test signal be transmitted.
- the measuring device 28 After triggering the measurement process, that is carried out by the measuring device 28 further sections of the reference signal from the hard disk Read 242 and together with that on the receiving line 22 received test signal output, i.e. to the measuring device 28 transferred.
- the first output 26a and the second output 26b can be four-channel audio interfaces or with stereo outputs the left channel and the right channel of the digital Be audio signal. The left channel can then use the test signal transmitted, which corresponds to the output 26b, whereas the right channel, i.e. output 26a, the reference signal from disk 242 will transmit.
- the delay between the reference and the test signal automatically fixed because the section of the Values of the reference signal with the continuous bit stream of the received test signal is compared.
- a new section values of the reference signal from the jingle detector transmitted to the measuring device corresponds to the values of Test signal, on which the reference signal is based, since the Transmission of further sections of the test signal to the measuring device only starts when the jingle detector assumes that the present section of the values of the Test signal that is currently used for correlation evaluation was the section to which the correlation determination was used section of the values of the reference signal underlying.
- the entire jingle minus the first Section of the values of the reference signal for quality assessment available for the meter.
- the whole jingle must have been played first in order to then to be able to determine that the current test signal was a jingle.
- the delay between the two is known, the delay being inherent in principle less than a section or frame length this delay can also be compensated for. That of the jingle detector 24 for determining the match used first section of the reference signal can also be used for the measurement procedure for quality assessment of audio signals are provided when both Signals simultaneously from the digital signal processor card be issued.
- the reference signal on the hard drive 242 is stored continuously, whereas the test signal is only cached for correlation. After finding the correspondence between the section of values of the reference signal and values of the test signal become more received values of the test signal in the jingle detector 24 not temporarily stored, but directly to the measuring device 28 output via the second output 26b.
- the first section of the values of the reference signal also for Measurement can be used, this is only possible if both signals from the digital signal processor card at the same time 244 are output. If the digital signal processor card 244 has sufficient RAM, a longer section of the test signal in the Memory held and delayed.
- the further section is then from the measuring device 28 with a corresponding Section of the test signal for quality assessment of the Test signal used. As described above can also be done by caching a longer one Section of the test signal the first section of the reference signal and the corresponding section of the test signal used for quality assessment by the measuring device 28 become.
- the measuring device 28th program in a manner known to those skilled in the art that the start and end of the measurement phase are automatically recognized become.
- the start and end of the measurement phase are determined by the Communication line 26c from the jingle detector 24 to Measuring device 28 transmitted.
