Definitions
- the invention relates to a method for carrying out announcements in a means of transport, such as in an airplane, a bus, a ship, a train etc.
- a playback device may be a video / audio data playback monitor installed in the passenger cabin, with each passenger having a headphone jack for playback of the associated audio data via headphones, for example, in the armrest of the passenger seat.
- seat monitors assigned to a passenger seat are conceivable as playback devices, with the associated audio reproduction likewise taking place via a headphone connection integrated in the passenger seat.
- announcements it is necessary to interrupt playback of video / audio data on the players of the entertainment device at least for the duration of the announcement in order not to obstruct the announcement and reach each passenger.
- a message start signal from the announcement device to the entertainment device at the beginning of an announcement.
- the transmission of the announcement start signal can be done, for example, wired from a server of the announcement device to the data server of the entertainment device.
- the entertainment device then, upon receipt of the announcement start signal, automatically initiates the interruption of playback on the playback devices.
- the data server of the entertainment device to send a corresponding playback stop signal to each player.
- the transmission of the video / audio data to be played back from the data server of the entertainment device is wired to a router and from there wirelessly to each playback device.
- the transmission path of the signals from the announcement device to the entertainment device for interrupting the reproduction on a playback device is prone to error. If the data server of the entertainment device fails, the announcement start signal can not be recognized by the entertainment device. Upon failure of the router of the entertainment device, the playback stop signal from the data server can not be transmitted to the playback devices. In addition, radio signal interference may hinder the signal transmission. As a result, there is a risk that the playback of Video / audio data on the playback devices is not interrupted during an announcement and passengers ignore the announcement.
- the invention has for its object to provide an improved method for performing announcements in a means of transport.
- an audio signal is output through the paging speaker or pagers, which is detected by the entertainment device, wherein the detection of the audio signal by the entertainment device automatically triggers an interruption in playback by each playback device.
- the playback apparatus can be caused to interrupt playback even if the data server or the router of the entertainment equipment fails and / or radio signal interference inhibits signal transmission.
- the playback device is typically equipped with its own microphone for receiving the audio signal output by the through-speakers.
- the audio signal may be the announcement signal itself.
- each reproducing apparatus is provided with an audio signal analyzer connected to the microphone of the reproducing apparatus, which analyzes and identifies the announcement signal, and distinguishes, in particular, from other audio signals such as noises in the passenger cabin or passengers' voices.
- the audio signal analyzer can detect, for example, the carrier frequency of the announcement signal generated by the announcement speaker and / or the total distortion of the acoustic harmonic of the announcement signal.
- the audio signal transmitted by the announcement loudspeaker and detected by the entertainment device may be an audible pre-signal transmitted before the announcement begins.
- the pre-signal may be, for example, a two-channel sound, which interrupts the playback.
- a post-signal for example in the form of a special final tone, which is detected by the entertainment device and triggers the continuation of the playback by the playback device can then be transmitted by the paging loudspeaker.
- the pre-signal and the post-signal are respectively detected by a microphone of the playback device.
- the announcement device may have an announcement memory, for example in the form of a data server with stored announcements and / or be provided with a microphone for receiving announcements, which is spoken by a person, for example a train or flight attendant.
- an announcement memory for example in the form of a data server with stored announcements and / or be provided with a microphone for receiving announcements, which is spoken by a person, for example a train or flight attendant.
- the receipt of the audio signal by the entertainment device or by the playback device also triggers the reproduction of an optical indication on the playback device.
- the visual indication indicates the performance of the announcement in order to increase the attention of the passenger.
- the playback device can be provided with a voice recognition device that converts the recorded announcement signal into text that is output on the playback device. This also allows passengers with reduced hearing detect the content of the announcement.
- the playback device outputs a detected announcement signal as an acoustic signal in order to improve the audibility of the announcement, for example via the headphone jack in a passenger seat.
- a detected announcement signal as an acoustic signal in order to improve the audibility of the announcement, for example via the headphone jack in a passenger seat.
- the exemplary embodiment relates to announcements in an aircraft.
- the aircraft is provided with an announcement device 12, which consists of an announcement memory 22, an announcement microphone 24 and an announcement loudspeaker 14.
- an announcement memory 22 typical announcements can be stored.
- the microphone 24 enables the recording of announcements, which are played back in real time via the announcement speaker 14. In this case, a large number of through-speakers 14 are provided in the aircraft cabin.
- the aircraft is also provided with an entertainment device 16, which consists of at least one data server 20, several WLAN routers 26 and a plurality of playback devices 18.
- an entertainment device 16 which consists of at least one data server 20, several WLAN routers 26 and a plurality of playback devices 18.
- On the data servers 20 video films, music data and video games are stored, which can be individually selected via each playback device 18 individually.
- Each passenger seat is assigned a reproduction device 18 in the form of a so-called in-seat monitor integrated into the backrest of the respectively front passenger seat.
- each player 18 has a headphone jack and a headphone, not shown in the figure for playback of the associated audio data.
- the data reproduced via the playback devices 18 are first transmitted by cable from the data server 20 to the WLAN routers 26.
- the WLAN routers 26 convert the data into a radio signal, which is transmitted to corresponding radio receivers of the playback devices.
- the transmission from the data server 20 to the playback devices 18 can also be made by cable.
- the announcement memory 22 first sends a message start signal 28, for example of the form "PA is in progress" (PA: Public Announcement) to the data server 20 of FIG Entertainment device 16.
- PA Public Announcement
- the data server 20 sends this signal via the wireless router 26 to each playback device 18 in order to interrupt playback there and to issue an optical indication "PA is in progress".
- the announcement memory 22 also sends the announcement signal for output to the announcement loudspeakers 14, which output the announcement signal 32 in an acoustic form.
- the announcement memory 22 first causes the output of a preamble signal 30 in the form of a bilingual tone output via the paging loudspeakers 14.
- Each player 18 is provided with a microphone.
- the player 18 Upon receipt of the pre-signal 30 by the microphone of a player 18, the player 18 automatically stops playing video / audio data.
- each reproduction device 18 is provided with an audio signal processing processor.
- the message "PA is in progress" is output on the screen of the player 18.
- the announcement signal 32 detected by the speaker of a display device 18 is transmitted to the headphones of the playback device 18 via the audio signal processing processor of the playback device.
- the audio signal processing processor has speech recognition which converts the speech of the announcement signal 32 into text output from the audio signal processing processor on the monitor of the display device 18.
- the data memory 20 Upon completion of the announcement, the data memory 20 transmits a post-signal in the form of a final tone of a particular frequency via the page-through loudspeakers 14. Upon receipt of the Nachsignals by the microphone of a Playback device 18 causes it to continue playing the video / audio data.
- the audio signal processing processor of each player 18 is also capable of detecting the carrier frequency, ie the envelope of the announcement signal 32 transmitted by the announcement loudspeakers 14, and of distinguishing the announcement signal 32 from other acoustic signals, such as passenger voices or engine noises, based on the carrier frequency. Additionally or alternatively, the audio signal processing processor of each player 18 may be configured to detect the total distortion of the acoustic harmonic of the loudspeakers 14 (THD: Total Harmony Distortion) in order to distinguish the announcement signal from other sounds.
- TDD Total Harmony Distortion
- the audio signal processing processor of the player 18 detects that the playback of the announcement signal 32 has ended, it causes the player 18 to continue playing the video / audio data.
