- stockage sous forme numérique, au niveau du centre de diffusion local, du message reçu, et
- conversion sous forme analogique, au centre de diffusion local, à l'instant déterminé, du message numérique reçu et insertion du message dans le programme diffusé localement.

- FIG. 1 is a diagram illustrating the constituents of a network suitable for implementing the method according to the invention in a particular application thereof,
- FIGS. 2A to 2D are flow charts of the programs used in the execution of the method.
Un mode de réalisation de l'invention sera décrit ci-après dans le cadre d'une application particulière consistant dans l'insertion de messages dans un programme de radio-diffusion qui est rediffusé localement.An embodiment of the invention will be described below in the context of a particular application consisting in the insertion of messages in a radio broadcast program which is rebroadcast locally.
Il existe des programmes de radio-diffusion qui couvrent un territoire étendu en utilisant un satellite servant de relais entre un émetteur central et des ré-émetteurs implantés dans des centres de diffusion locaux. Dans chaque zone géographique couverte par un ré-émetteur local, il est intéressant d'insérer, dans le programme général retransmis par satellite, des messages n'intéressant que les auditeurs de la zone géographique considérée, par exemple des messages publicitaires pour des entreprises ou des événements locaux ou des messages d'informations locales.There are radio broadcasting programs that cover a large area using a satellite that acts as a relay between a central transmitter and re-transmitters located in local broadcasting centers. In each geographic area covered by a local retransmitter, it is interesting to insert, in the general program retransmitted by satellite, messages of interest only to the listeners of the geographic area considered, for example advertising messages for companies or local events or local information messages.
Pour des raisons évidentes d'économie en personnel et en matériel, la réalisation des messages locaux est assurée dans un site central, qui peut ou non être celui de l'émetteur central. Actuellement, les messages, enregistrés sur bandes magnétiques, sont acheminés aux différents centres de diffusion locaux. L'insertion des messages enregistrés dans le programme général est réalisée par un opérateur qui, à des instants déterminés, commande l'interruption du programme général et la diffusion de ces messages par le ré-émetteur local.For obvious reasons of economy in personnel and material, the realization of the local messages is ensured in a central site, which can or not be that of the central transmitter. Currently, the messages, recorded on magnetic tapes, are routed to the various local broadcasting centers. The insertion of the messages recorded in the general program is carried out by an operator who, at determined times, controls the interruption of the general program and the broadcasting of these messages by the local retransmitter.
L'insertion des messages peut être effectuée en réponse à la détection d'un signal spécifique émis par l'émetteur central et retransmis par le satellite. Il est alors nécessaire que l'opérateur, dans chaque centre de diffusion local, soit très attentif à la détection de ce signal.The insertion of messages can be carried out in response to the detection of a specific signal emitted by the central transmitter and retransmitted by the satellite. It is then necessary that the operator, in each local broadcasting center, be very attentive to the detection of this signal.
Le procédé selon l'invention permet une insertion automatique des messages dans le programme diffusé localement.The method according to the invention allows automatic insertion of messages into the locally broadcast program.
La figure 1 illustre très schématiquement un réseau de radio-diffusion avec un émetteur central 10 dont les signaux sont retransmis par un satellite 12 vers des centres de diffusion locaux 30. Ceux-ci comprennent une antenne réceptrice 38 recevant les signaux du satellite pour leur rediffusion par un ré-émetteur local 31 et une antenne émettrice 39.Figure 1 very schematically illustrates a network of broadcasting with a
Conformément à l'invention, les messages sonores à insérer dans les programmes diffusés localement sont convertis sous forme numérique en un site central 20, transmis aux centres locaux 30 sous forme numérique par l'intermédiaire d'un réseau de communication numérique 40 et sont, dans les différents centres locaux 30, convertis sous forme analogique pout être diffusés par les ré-émetteurs locaux aux instants voulus.In accordance with the invention, the audio messages to be inserted in the programs broadcast locally are converted in digital form to a
Le site central 20 peut être celui où l'émetteur 10 est implanté, ou en être différent. Le matériel nécessaire à la fabrication et à l'enregistremant analogique des messages, c'est-à-dire la préparation du texte, le mixage éventuel avec un fond musical, et l'enregistrement sur bande magnétique, comprend par exemple un magnétophone 21 avec un microphone 21a et un égaliseur 21b installés au site central 20.The
En vue de leur acheminement dans les centres locaux concernés, les messages sont convertis sous forme numérique et stockés en mémoire d'une unité de traitement informatique du site central. A chaque message peut être associée notamment une information d'adresse identifiant le centre de diffusion local auquel il est destiné ainsi que le programme horodaté de diffusion.With a view to their routing in the local centers concerned, the messages are converted into digital form and stored in the memory of a computer processing unit at the central site. Each message can be associated in particular with address information identifying the local broadcasting center for which it is intended as well as the time-stamped broadcasting program.
Les signaux de sortie du magnétophone 21 sont échantillonnés au moyen d'un circuit d'échantillonnage 22. L'unité de traitement informatique comprend un micro-ordinateur 23 équipé d'un circuit 26 de conversion analogique/numérique, codage et compression de données numériques. Un tel circuit est connu en soi. Les données produites par ce circuit en réponse aux signaux reçus du circuit d'échantillonnage 22 sont stockés en mémoire au moyen du micro-ordinateur 23, par exemple sur disque dur. Le micro-ordinateur 23 fait fonction de serveur pour assurer la transmission des messages vers les centres de diffusion locaux via le réseau numérique 40. Celui-ci est avantageusement le réseau numérique à intégration de services (RNIS) public.The output signals from the
A cet effet, le micro-ordinateur 23 est raccordé au réseau 40 par l'intermédiaire d'un circuit d'interface 24 de type SO et un circuit 25 d'accès au RNIS. Les circuits 24 et 25 sont bien connus. Ils pourront être constitués par les circuits référencés "Device SO" de la société française SCII ou "PC SNET" de la société française OST.To this end, the
Chaque centre de diffusion local 30 comprend un micro-ordinateur esclave 33 raccordé au réseau 40 par un circuit d'interface 34 de type SO et un circuit 35 d'accès au RNIS, les circuits 34 et 35 étant analogues aux circuits 24 et 25.Each
Le micro-ordinateur 33 comprend une mémoire de masse telle qu'un disque dur dans laquelle sont enregistrés les messages transmis sous forme numérique par le réseau 40. Le micro-ordinateur 33 est également équipé d'un circuit 36 propre à assurer la décompression, le décodage et la conversion numérique/analogique des messages enregistrés, c'est-à-dire un circuit réalisant les opérations inverses de celles effectuées par le circuit de conversion analogique/numérique, codage et compression du micro-ordinateur 23. Ces deux circuits 26 et 36 équipant les micro-ordinateurs 23 et 33 peuvent par exemple être constitués par des cartes de numérisation et compression de sons utilisant le procédé de compression MICDA-SB (Modulation par Impulsions et Codage Différentiel Adaptatif en Sous-Bandes) du CNET (Centre National d'Etudes des Télécommunications) ou le procédé MASCAM (WB48SBC) du CCETT utilisant les propriétés psychoacoustiques en bandes critiques.The
Les signaux analogiques correspondant aux messages lus dans la mémoire de masse du micro-ordinateur 33 et convertis sous forme analogique après décompression et décodage sont transmis au ré-émetteur 31.The analog signals corresponding to the messages read from the mass memory of the
Le cas échéant, le ré-émetteur 31 peut détecter, dans les signaux reçus du satellite 12, d'éventuels signaux codés de synchronisation indiquant le début d'une insertion de message local. En réponse à la détection d'un tel signal de synchronisation, par exemple par décodage de sa fréquence et de sa durée, le ré-émetteur 31 produit un signal de commande, par exemple par fermeture d'un relais, qui est appliqué au micro-ordinateur 33 pour déclencher celui-ci qui est en veille et commander la lecture d'un message ou d'une séquence de messages enregistrés. Simultanément, le ré-émetteur est commuté en entrée pour permettre la diffusion des messages locaux.If necessary, the
En variante, la lecture d'un message en vue de sa diffusion est commandée à une heure déterminée conformément à une information de programmation associée au message, la détection de l'heure étant assurée au moyen de l'horloge interne du micro-ordinateur 33.As a variant, the reading of a message with a view to broadcasting it is controlled at a determined time in accordance with programming information associated with the message, the time being detected by means of the internal clock of the
En fin de diffusion des messages locaux, le micro-ordinateur 33 produit un signal qui provoque à nouveau la commutation du ré-émetteur afin de relier à nouveau l'entrée de celui-ci à l'antenne réceptrice 38.At the end of the broadcast of the local messages, the
Les étapes de stockage, programmation et transmission des messages numériques via le RNIS aux différents centres de diffusion locaux et restitution des messages stockés dans les mémoires de masse des micro-ordinateurs 33 des centres de diffusion locaux sont réalisées par des programmes dont l'organisation et les ordinogrammes sont illustrés par les figures 2A à 2D.The steps for storing, programming and transmitting digital messages via ISDN to the various local broadcasting centers and restoring the messages stored in the mass memories of the
Le programme exécuté par le micro-ordinateur serveur (ou maître) 23 comprend des modules dont l'enchaînement est illustré par la figure 2A.The program executed by the server (or master)
Le menu principal 100 offre le choix entre des modules de studio 110, de programmation 120 et de réseau 130.The
Le module studio 110 permet d'accomplir les fonctions de numérisation des messages (module 112) et de mixage et effets spéciaux (module 114).The
La numérisation des messages consiste dans le déclenchement de la lecture des messages analogiques enregistrés et le stockage en mémoire de masse des messages numérisés. Le module de numérisation offre également l'accès en mémoire pour la suppression de messages devenus inutiles.Digitization of messages consists of the triggering of the reading of recorded analog messages and the storage in mass memory of the scanned messages. The module scanning also provides memory access for deleting unnecessary messages.
Le module de mixage et effets spéciaux permet de travailler sur les messages numérisés. Les effets spéciaux consistent par exemple dans l'introduction d'écho, l'inversion, l'amplification, la réverbération, ... Il s'agit de techniques bien connues en elles-mêmes.The mixing and special effects module allows you to work on digitized messages. Special effects consist for example in the introduction of echo, inversion, amplification, reverberation, ... These are techniques well known in themselves.
Le module programmation 120 permet la création, la modification, la duplication et la suppression de fiches de programmation par un opérateur. Une fiche correspond à une programmation pour une plage horaire d'un jour donné pour un centre de diffusion local et contient la liste des messages à diffuser avec le jour et la plage horaire de diffusion.The
Le module réseau 130 assume notamment la fonction de transmission de programmation vers les centres de diffusion locaux. Cette transmission est effectuée de façon automatique, chaque nuit et pour chaque centre de diffusion local.The
Comme le montre la figure 2B, la transmission de programmation comprend les étapes suivantes :
- création puis envoi d'un fichier "programmation" contenant les fiches de programmation pour la journée suivante, et d'un fichier "liste des messages nécessaires" contenant la liste des messages nécessaires pour assurer la programmation prévue,
- réception d'un fichier "messages manquants" créé par le centre de diffusion local et contenant la liste des messages nécessaires pour assurer la programmation voulue, mais non disponibles dans la mémoire du micro-ordinateur esclave du centre de diffusion local, et d'un fichier "historique" créé par le centre de diffusion local et contenant la liste des messages effectivement diffusés lors de la journée passée et l'heure de leur diffusion,
- transfert des messages manquants sous forme numérique pour stockage en mémoire du micro-ordinateur esclave, et
- mise à jour du fichier "historique" des messages en vue notamment d'une facturation en fonction du nombre et de l'heure de diffusion.
- creation then sending of a "programming" file containing the programming sheets for the following day, and of a "list of necessary messages" file containing the list of messages necessary to ensure the scheduled programming,
- reception of a "missing messages" file created by the local broadcasting center and containing the list of messages necessary to ensure the desired programming, but not available in the memory of the slave microcomputer of the local broadcasting center, and a "history" file created by the local broadcasting center and containing the list of messages actually broadcast during the past day and the time of their broadcast,
- transfer of missing messages in digital form for storage in memory of the slave microcomputer, and
- updating the "history" file for messages, in particular for billing according to the number and time of broadcast.
La figure 2C montre l'enchaînement des modules du programme exécuté par le micro-ordinateur esclave 33 de chaque centre de diffusion local.FIG. 2C shows the sequence of modules of the program executed by the
Le programme est en attente dans une boucle 150 et passe au module réseau 160 ou diffusion 170 lorsque ces modules sont appelés.The program is on standby in a
Le module réseau 160 assure notamment la réception de la programmation. Cette réception se déroule suivant les étapes suivantes (montrées sur la figure 2B en concordance avec les étapes de transmission de programmation) :
- réception des fichiers "programmation" et "liste des messages nécessaires",
- création du fichier "messages manquants",
- suppression des messages inutiles en mémoire de masse par comparaison entre les messages stockés et la programmation,
- envoi au site central du fichier "messages manquants" et du fichier "historique" pour le jour écoulé (le fichier "historique" étant remis à jour après chaque diffusion de message),
- réception des messages manquants et stockage dans la mémoire de masse du micro-ordinateur 33, et
- tri des fiches de programmation contenues dans la programmation reçue, afin de les ordonner par ordre chronologique, le programme se positionnant sur la première fiche future.
- reception of the "programming" and "list of necessary messages" files,
- creation of the file "missing messages",
- deletion of unnecessary messages in mass memory by comparison between stored messages and programming,
- sending the "missing messages" file and the "history" file for the past day to the central site (the "history" file being updated after each message broadcast),
- reception of the missing messages and storage in the mass memory of the
microcomputer 33, and - sorting of the programming files contained in the received programming, in order to order them in chronological order, the program being positioned on the first future file.
Le module diffusion 170 est appelé lorsqu'il ne reste qu'un temps prédéterminé T avant l'heure de diffusion prévue pour le premier message de la première fiche, ceci étant détecté par scrutation d'une horloge interne au centre de diffusion local.The
La diffusion des messages comprend les étapes suivantes (figure 2D) :
- chargement des messages sélectionnés, c'est-à-dire ceux figurant sur la première fiche de programmation (le chargement est effectué par lecture en mémoire de masse et transfert en mémoire vive du micro-ordinateur des messages à diffuser),
- détection de l'instant de diffusion par scrutation de l'horloge interne,
- diffusion des messages, par commutation du ré-émetteur sur la sortie de la carte 36 et transmission à celui-ci des messages à diffuser,
- mise à jour du fichier "historique", et
- positionnement sur la fiche ce programmation suivante.
- loading of the selected messages, that is to say those appearing on the first programming form (the loading is carried out by reading in mass memory and transfer in RAM of the microcomputer of the messages to be broadcast),
- detection of the broadcasting time by scanning the internal clock,
- broadcasting of the messages, by switching the re-transmitter to the output of the
card 36 and transmission to the latter of the messages to be broadcast, - update of the "history" file, and
- positioning on the form of this following programming.
Dans le cas où la diffusion est déclenchée par un signal de synchronisation transmis par satellite, l'instant de diffusion est déterminé par détection de la réception de ce signal, et non pas par scrutation de l'horloge interne.In the case where the broadcast is triggered by a synchronization signal transmitted by satellite, the broadcast instant is determined by detection of the reception of this signal, and not by scanning the internal clock.
Les fonctions décrites ci-avant sont celles spécifiquement liées à la fabrication, au stockage, au transfert et à la diffusion des messages.The functions described above are those specifically related to the production, storage, transfer and dissemination of messages.
Les moyens disponibles pourront être mis à profit pour assumer d'autres fonctions comme, par exemple, la télésurveillance et la télé-maintenance des centres de diffusion locaux.The means available can be used to assume other functions such as, for example, remote monitoring and remote maintenance of local broadcasting centers.
Le procédé décrit ci-avant est remarquable en ce qu'il permet l'insertion de messages locaux dans un programme de radio-diffusion général par des moyens automatiques au niveau de chaque centre de diffusion local. Ceci est permis grâce au réseau numérique 40 qui permet un téléchargement des messages numérisés. Le téléchargement pourra être réalisé par exemple la nuit, à un coût minimum. On notera que les moyens décrits pourraient permettre une diffusion en temps réel, dans la mesure où le réseau 40 assure un débit suffisant.The process described above is remarkable in that it allows local messages to be inserted into a general broadcasting program by automatic means at each local broadcasting center. This is allowed thanks to the
En outre, la numérisation des messages sonores, non seulement autorise un acheminement de ceux-ci aux centres locaux aux moindres coûts, en utilisant un réseau tel que le RNIS, mais de plus permet une restitution d'un son de haute qualité.In addition, the digitization of audio messages not only allows them to be routed to local centers at the lowest cost, using a network such as ISDN, but also allows the reproduction of high-quality sound.
Le réseau peut servir aussi au téléchargement de programmes utilisés par les micro-ordinateurs des centres de diffusion locaux, ainsi qu'à la maintenance et aux modifications éventuelles de ces programmes.The network can also be used to download programs used by microcomputers in local broadcast centers, as well as to maintain and modify these programs if necessary.
Par ailleurs, une réinitialisation complète des disques durs des micro-ordinateurs des centres de diffusion locaux peut être effectuée périodiquement pour éviter les sectorisations trop importantes de ces disques.In addition, a complete reset of the hard disks of the microcomputers of the local broadcasting centers can be performed periodically to avoid excessive sectoring of these disks.
Bien entendu, par souci de sécurité, les transmissions entre le site central et un centre de diffusion local peuvent n'être autorisées qu'après double identification. Une première identification est effectuée dès que le site central appelle le centre de diffusion local puisque ce dernier peut identifier l'appellant sur le RNIS. Une deuxième identification peut ensuite être effectuée par rappel du site central par le centre de diffusion local avec envoi d'un code d'identification que le site central aura généré aléatoirement et envoyé préalablement au centre de diffusion local.Of course, for security reasons, transmissions between the central site and a local broadcasting center may only be authorized after double identification. A first identification is carried out as soon as the central site calls the local broadcasting center since the latter can identify the caller on the ISDN. A second identification can then be carried out by recalling the central site by the local broadcasting center with the sending of an identification code that the central site will have generated randomly and sent beforehand to the local broadcasting center.
On notera encore que, bien que l'on ait envisagé une retransmisison du programme général de radio-diffusion par satellite, l'application décrite peut fonctionner de façon similaire dans le cas d'une retransmission par voie hertzienne directe entre l'émetteur central et les ré-émetteurs locaux.It will also be noted that, although a retransmission of the general program of satellite broadcasting has been envisaged, the application described can operate in a similar manner in the case of a retransmission by direct hertzian channel between the central transmitter and local re-transmitters.
Comme déjà indiqué, l'application décrite ci-avant a été donnée à titre d'exemple d'utilisation du procédé conforme à l'invention.As already indicated, the application described above has been given by way of example of use of the method according to the invention.
Ainsi, le procédé pourra être mis en oeuvre non pas pour insérer des messages dans un programme radio-diffusé par un ré-émetteur local, mais, par exemple, pour insérer des messages dans un programme diffusé en un lieu tel qu'un lieu public, un lieu de travail, un centre commercial ...Thus, the method can be implemented not to insert messages in a program broadcast by a local rebroadcaster, but, for example, to insert messages in a program broadcast in a place such as a public place , a workplace, a shopping center ...
