Title (EN) METHOD AND SYSTEM FOR SUBSCRIPTION TELEVISION BILLING AND ACCESS
(FR) METHODE ET SYSTEME DE FACTURATION D"ABONNEMENT ET D"ACCES A LA TELEVISION
Abstract: front page image
(EN)A subscription television system and method in which billing information regarding programs actually viewed by a subscriber of the system is accumulated (20) over nondedicated telephone lines. A scrambled television program signal containing a block of television program material (14), a program identification code (18) unique to the block of program material, and a program category code (18), is broadcast (16). The codes are preferably included in the vertical retrace interval of the video portion of the program signal and the transmitted program signal is selectively received at a subscriber station (12) and selectively unscrambled (24) to permit viewing of the block of program material being transmitted in response to subscriber action (30) indicating acceptance for viewing of the block of program material. The received program category code is compared (92) with a locally generated category code (90) to determine whether the program is acceptable for viewing. The program identification code is detected (64) and stored (68) for subsequent transmission in response to the subscriber action indicating acceptance for viewing of the received block of program material. The program identification code stored at the subscriber station is selectively accessed from a remote location (10) over telephone lines on other than a real time basis (e.g., a periodic basis) to thereby provide billing information at the remote location as to programs actually viewed by the subscriber. The subscriber can thus be billed monthly or on some desired periodic basis for programs actually viewed during the preceding period. The billing period can be varied (32, 70) from the remote location (10) to provide a means to control the number of programs which a subscriber can receive.
(FR)Systeme et methode de television par abonnement dans lequel des informations de facturation concernant les programmes qu"un abonne au systeme a effectivement regarde sont accumules (20) sur des lignes tele phoniques non reserves. Un signal de programme de television brouille contenant un bloc d"un materiau de programme de television (14), un code d"identification de programme (18) correspondant de facon unique au bloc de materiau de programme, et un code de categories de programmes (18), est diffuse (16). Les codes sont de preference compris dans l"intervalle de retour vertical de la partie video du signal de programme et le signal de programme transmis est selectivement recu dans une station d"abonnes (12) et selectivement debrouille (24) pour permettre la visualisation du bloc de materiau de programme transmis en reponse a une action de l"abonne (30) indiquant l"acceptation pour la visualisation du bloc du materiau de programme. Le code de categorie de programme recu est compare (92) a un code de categorie produit localement (90) pour determiner si le programme est accepte pour sa projection. Le code d"identification du programme est detecte (64) et emmagasine (68) pour une transmission ulterieure en reponse a une action de l"abonne indiquant qu"il accepte de regarder le bloc de programme recu. L"acces selectif du code d"identification de programme emmagasine a la station de l"abonne se fait a distance (10) par des lignes telephoniques sur une base autre qu"en temps reel (par exemple periodique) de maniere a donner au centre a distance une information sur la facturation quant aux programmes effectivement visualises par l"abonne. On peut ainsi facturer mensuellement a l"abonne ou, d"une maniere differente, periodiquement pour les programmes qu"il a effectivement regarde pendant la periode ecoulee. La periode de facturation peut etre modifiee (32, 70) a partir du centre a distance (10) de maniere a pouvoir commander le nombre de programmes qu"un abonne peut recevoir.
