Definitions
- a method and system for offline access to broadcast information from a set of broadcast sources is provided.
- users wishing to listen to information broadcast by a radio source have the possibility of doing so without any particular equipment at home other than a telephone set, by remaining online and by selecting any time of their choice.
- the subject of the present invention is more particularly, first of all a method for deferred access to radio information broadcast by one or more broadcasting sources mainly characterized in that it comprises the following stages:
- the present invention also relates to a system for delayed access to radio information broadcast by one or more broadcasting sources, mainly characterized in that it comprises: A) a center for receiving broadcast information, recording and management of read and write access, accessible via the switched telephone network, this center comprising:
- - a central processing and management unit capable of digitizing in real time the information received by the receivers and recording them cyclically continuously with time marks corresponding to broadcasting time slots; and determining in which time slot of the recording any information already broadcast is situated; - means for receiving telephone calls and transmitting the requested information online,
- B) user equipment comprising telecommunication terminals allowing the interactive interrogation of the recording center and the online reception of the desired information through the switched telephone network.
- the center can receive directly by hertzian wave, the information diffused by the hertzian sources.
- a receiver is placed in the radiation field of the source and is connected to the center by appropriate transmission means.
- FIG. 1 shows schematically an access system according to the invention
- FIG. 1 shows a more detailed diagram of the system as shown in Figure 1.
- the radio sources likely to be made available offline are grouped together with the reference 100 in this figure 1. Each source transmits radio information likely to be received and listened to by radio receivers.
- a recording reception and access management center 200 for receiving the broadcasts broadcast by all of these sources, recording them and retransmitting them online to users, on call from these users and this through the switched telephone network.
- this recording and management center 200 has a set of radio receivers, bearing the reference 201, digitization and storage means 202 making it possible to make recordings, and a set of line interfaces 203.
- Each radio receiver is set to a broadcasting frequency from a given source and is connected to the recording means 202 so as to record the broadcasts in real time. This information is continuously recorded cyclically over a given period, for example 24 hours. More specific details on registration will be given in the following description.
- the center is equipped to receive radio information directly by radio waves (as shown by arrows in this figure).
- a receiver 150 is placed in the radiation field of the source and is connected to the center by appropriate transmission means 170 such as for example a link digital specialist or not.
- the center is equipped with a classic line interface assembly in itself allowing receive all telephone calls received by the recording and management center so as to answer these calls and allow the retransmiss.lo._E-i of each information requested by each call. Also shown in this figure is the user equipment allowing interrogation of the recording center, in the form of a block bearing the reference 300.
- This equipment consists of telecommunication terminals which can be reduced, for example, to simple telephone sets with voice frequency.
- FIG. 2 shows a more detailed example of an access system according to the invention.
- a receiver 23 is provided for each broadcasting source S1, S2, Sn.
- the output of each receiver 23 is connected to a digitization circuit 22, it is a set of conventional analog-digital converters.
- the digitized information is transmitted to a central processing unit 20 which stores it in a storage medium 24.
- This unit is produced by means of a computer and its storage peripherals in which an application program has been loaded, implementing implements the process described.
- the computer can in particular be configured as a data server. We can take for example to implement the process a computer running the UNIX operating system.
- the broadcast, digitized information can be stored on the hard drive of this computer or on a digital optical disc, or any other equivalent storage device allowing simultaneous recording and playback without delay.
- the central unit also receives all of the calls that can be made from telephone sets 301, 302, etc., using voice frequencies available to users. Calls are received by devices such as voice frequency responders, capable of:
- the central unit 20 makes it possible, upon receipt of the requested broadcast time and possibly from the source (in the case of several sources), to obtain the corresponding information from the recording.
- the central unit 20 is able to respond to all of the requests sent by the answering machines and to transmit the required information to them, so that each answering machine sends the requested broadcast information, in voice form, to the users who are online.
- a user who wants to access any information broadcast at a time of his choice will proceed as follows: using a voice frequency telephone, or an equivalent telecommunications terminal, he will dial the telephone number of the registration and management center on the keypad of this extension. When communication is established, it receives a voice message from the latter asking it to give the time of broadcast and possibly the broadcasting source of the information it wishes to listen to. The user will either give this information orally or compose a code which will correspond to the hour and minute of the broadcast of the information he wants to listen to. If he wishes to listen to the information broadcast at 7.55 am, he will dial, for example, 0755 or simply, for example, 3, 3 corresponding to the code given to an information editorial from 07.55.
- the answering machine 21 is then provided to be able in this case to interpret the voice commands of the user in a manner similar to codes to voice frequency.
- the user will have previously transmitted the name of the broadcasting station for example by dialing a number assigned to this source SI. (For example n ° 1 for the SI source).
- the name of the source can be given orally by the user instead of being dialed on the keyboard, the answering machine 21 being then provided to be able in this case interpret the user's voice commands in a similar way to voice frequency codes.
- the processing unit 20 is able to recognize the pulses sent from these keys, as a function, when these pulses are received after dialing the call while the central unit controls the dialogue with the use or while reading a recording.
- the user can, during a call, either go back, advance or pause, by pressing dedicated keys.
- the processing unit 20 is then able to recognize the pulses sent from the dedicated keys when they are received after call dialing and the corresponding telephone connection, that is to say during the dialogue between the center user and answering machine.
- a function key can be provided defining a code for selecting particular information (for example: the "1" key makes it possible to obtain the last information flash of the day).
- the broadcast information is digitized as and when it is received (in real time) and recorded continuously.
- recording is presented as a "continuum” whose duration is a priori limited only by the characteristics of the systems and storage media for information on the server.
- the server records all the information from a radio source on a single message (a "continuum"), within the only limit of the maximum duration of this "continuum” (several hours).
- the server is able to manage read access so as to retransmit all or part of this "continuum” message.
- the server is capable of responding to any request for a "slice" of information coming from the user, by precisely calculating the To + N corresponding to this request (for example: To + N-15s, in response to the backtrack command).
- the difference between the requested time and the time actually listened to remains imperceptible for the user, for example, of the order of 300 ms.
- the server does not necessarily know how to keep read access to recorded information previously on the "continuum” (for example, June 1 from 3 am to 11 am) when he initializes a new recording on the "continuum” (for example, June 2 at 11 am). To allow users to read this previous information, it must be ensured that the new recording systematically starts on a "continuum” which will not be requested at the same time for reading previous information. d) Avoid any "hole” in the recording. To this end, we have chosen to overlap in time two successive "continuums” (for example: a radio broadcast is recorded: on a "continuum” until 02:00, the next starting at 01:30 - two recordings being thus available in parallel for the recovery period 01:30 - 02:00). e) Respect the normal operating cycle of the service (for example, the daily cycle for the service of access to radio information). f) While taking into account a) above, optimize the storage of information, which leads to avoiding too much overlap between two consecutive "continuums”.
- the recording can be carried out for example as follows: 1) The cycle retained for the recording is the daily cycle.
- n ° 3 P 3 the exact start and end times of each of the "continuums" that can be adjusted, respecting the. elements indicated above, depending on: the maximum listening time allowed (example: 20 minutes on the Audiotel kiosk currently set up in France), hours most listened to on each radio recorded, hours most loaded on the server, the recovery necessary to ensure the best possible reliability of access to the recorded information.
- the input channels of the information on the server can for example be paired, by two, in particular on the card ensuring the multiple recording of these sources of information.
- recording is activated on the two channels thus paired, the information recorded via these two. channels is the same at all times of common recording.
- the user can ask to listen to radio information that is located near the end of a message ("continuum").
- the overlap provided in the recording makes it possible to avoid the silences which then appear in a conventional embodiment and which are due to the passage of the server from one message to the next.
- the server chooses the youngest "continuum” (that is to say the “continuum” whose start time is earlier and closest to the time requested by the user).
- the method for determining C leads the server to choose the youngest "continuum”.
- the server allows the retransmission of a "continuum” without waiting for the recording on this "continuum” to be completed, that is to say at the end of the time provided for the "continuum"
- the delay between the moment when the information is recorded in the server and the moment when it can be listened to by the user is limited to the processing time by the server, for example 300 ms.
- the listening service "live on the antenna” is thus available, with however a small offset (for example of the order of 300 ms) between the emission on the antenna and the retransmission by the server to the user .
- a significant difference may occur between the time of transmission of the radio information (for example, an hourly chime on a radio source) and the time of recording by the server, that is to say the time at which the server notes that it records this radio information.
- the server - at least in its function of recording radio information always know the time at which this information is transmitted.
- the server can for example be kept at the exact time so as to constantly know the time corresponding to the radio information that it receives and records. To keep the server at the correct time, we will preferably proceed as indicated.
- the server should be equipped with a device allowing the server to automatically and permanently know the exact time, for example built on listening to the France Inter clock.
- Time adjustments are therefore made periodically, depending on the difference observed with the exact reference time.
- the information provided by the Numéris MIC clock (coming from the France Telecom network) can help limit time slippages.
- the recording is systematically calibrated to the exact GMT time.
- the user's choice of time is translated by the server in a precise manner " as to the exact moment at which listening should begin. on the "continuum” corresponding to the radiophonic information requested, moment defined in the form To + N (N equal to the number of seconds since the start of the "continuum”).
- the server In calculating this To + N, the server must: a) know precisely the time at which each "continuum” (To) begins; to do this, the start times for recording the "continuum” are systematically planned in advance, with synchronization of the server on the exact time; the server guarantees that the recording actually starts at the time when it is requested, to the nearest precision of the processing time - for example of the order of 300 ms. b) know the time at which listening to the "continuum” was interrupted by a user command, especially when the user wishes to return to back, go forward or take a break; to do this, the server notes, for the calculation of N, the exact time at which the user's commands are transmitted to it.
- the server having the exact time, can also mark the information which is necessary for the correct operation of the service, in particular within the framework of a communication log established by the server.
- the server is able to simultaneously record several sources of information, for example radio sources from the broadcasting means currently used; broadcasting on usual frequencies, for example by means of a tuner, broadcasting by satellite.
- sources of information for example radio sources from the broadcasting means currently used; broadcasting on usual frequencies, for example by means of a tuner, broadcasting by satellite.
- the "continuums" serving for the recording of several sources of information are accessible on the same user access.
- the information is also accessible as soon as it is recorded ("live” listening). For this, the server has several accesses for recording.
- these ports allow the server to record radio broadcasts through a tuner or equipment for receiving a satellite broadcast.
- a conventional telecommunications network for example, via a dedicated link, a switched telephone network, Numéris, etc.
- the information retransmitted to the user may be degraded.
- this may be due for example:
- the antenna is placed away from the server or other computer equipment.
- a tuner with automatic adjustment is used on the transmission frequency of the radio source.
- the recording device in the server is provided with a mechanism for systematic detection of noise or blanks on the transmission of information.
- the recording device is provided in the server with a mechanism for systematic detection of a recognition signal from the information transmitter, when this has been agreed in advance.
