W O 96/278~3 PCTrUS96/03137 COUPONING ISSUANCE AND TRACKING SYSTEM FOR A
COMMUNICATIONS NETWORK

FIELD OF THE INVENTION
The present iu~ llivu relates to a cvl~n~ c~l;ons nelwvlk and more particularly the present iu~enlion relates to the iulel aclive t- dllsrel of multimedia information for couy;>ù issuance l.acLug-within such a nelwulL.

BACKGROUND OF THE INVENTION
There are many types of co~~ ~l ons UetWUll~. What is meant by cou~ s r_twvll~ in the co~t~,~l of this appl;e~ n are n~lwvl~ which allows for the l~ on of i~o~ n t~'e~. For .~ ~le, a hotel or hospital would contain such netwu.l~. In such l-t,tWUll~, there are a series of cGnue~,Lons to each room or the like for ~ L~ of ~ ,us multimedia i~c-..-qtion. ort~,u~ s this i..~c,.ulalion takes the form of video lllatellal that is provided to each of the ~ o-..ers or patients.
The cha~a~,lelislic of these types of nelwulL~ is that there is a fee.lb~cl~
path that provides the owner of the ulf~ JlL with knowledge of the - ti~Les of the particuhr user on the nc,twulL. Hence, in the case of a hotel system, if a person orders a service there is a way for the owner of the nelwulL to know thatthe service has been or~ ~ed by that ~al L.,ular person.
The major pro~l-r~ with ~ 5 CGu~u~nir-q-~Qn~ nelwul}~ are that they are not fully interactive. That is, there is no way to actively select multimedia information from ~.. ls;de of the nelwulL in real time. This has ~ onal ~;g~ir;c~nce when ~ i.lg to produce coupons or other products to eucou~age a cl.-stc.mer to buy a particular product or the like. In addition, these buyingpatterns of a particular co~ ...er can not be adequately tracked within most cu..lulunications netwol}~. Finally, there is no way to determine any additionaldemographic information or other information from the user.

The pr~l.t i~ liv relates to an int,.Lcli.e system for a co~..;c~;ons netwv,L. The follvwi~g de2~ )liv~ is presented to enable one of ordinary skill in the art to make and use the i~_.. l;o" and is provided in the conte~t of a patent applic..lio~ and its requirements. Various mo~lifi~tiQns to the y~ efe~,_d embo~li~ent will be readib apparent to those skilled in the art and the generic ~ ,iples and fcatures described herein may be applied to other embodiments. Thus the present invenlion is not intended to be limited to the ' W 0 96/278~3 CA 02214711 1997-09-04 PCTrUS96103137 embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein.
Refell,ng now to Figure 1, what is shown in simple block diagram form is a prior art cv~unic,s-t~ons network. In the following .licc~Ccion, the pl,es--~tS invention will be ~liC~--e~ in the context of a hotel system. It should be undel~lood hc,..~,~er that there are other 'ypes of communications nelwolL~ suchas hospitals, e~ c-t;~ al ;..'l;~ ..C and many conire~lLional head end ndwurl~
or the l ke where the ~m~"~les of the l,r~t i~ . would apply.
The system 10 inclu~es a hotel PBX system 12 for receivillg and trana~iuillg t ~ le~honc calls~ l,rc~el ~ management system 14 and a video control system 16 which could be used to access the pay pcr view movies or the lilce. The video control system 16 ~' ~ s an in-room remote link and is Co~ G~ to the Scl~iCeS O~e~la ~ n platform 14. The l,ro~cl~ ms~agement system (PMS) 14 keeps track of the users that order the movies.
The system 10 as above ~ eJ is not ful~ er~ In tbis type of system there are a ~ of video units or VCRs l~te~l within the system and they are switched in when the a~;o~lialc ~,..sl~--..er or client wants to use t_e vidco unit. Hence, these video units cannot be indiviA~ 7P~l to a ~J&l ~.,lar user l.e~,,- ~ there are simply not eroll~h units. For . ~le, there may be a bank of 64 VCRs which would se.~ice a 500 room hotel. Each of the VCRs would have a separate movie. Accordingly, in this case there is a l,os~ll,ility that apal ~ular movie would not be available. In addition, this type of arrangement s~ cly limits the number of choices available.
Before the ~ r~c~t inv~ ion is deswibed in detail certain background i~fo.. ~.~t;o-- should be ~licc~ ~' to clarif~ the utility of the present invention in terms of ~ ;~; c~ ..ic~tions networks. In a multimedia system, various sensory info....s~ion is provided to a receiver. In the case of video information, this i.lfc.. ahon takes the form of foreground and background images that display a l,a, L~;ular scene. In the case of audio information, the foreg. ound and ~ WO 961278~3 CA 02214711 1997 - 09 - 04 PCTrUS96/03137 background signals are such that the foreground information is speech and the background information is music.
TypicaDy, multimedia systems in whatever form provide this information over a single tr~q-ncmicQion line. In so doing, the amount and quality of the 5multimedia inform-qtion is s_.,. rcly limited by the bandwidth of the tr~ncmi~;on line.
The ~;~sent i~ nli~>n first di~f~re-~t;atGs l,~t~,~ell i~pvlldnt and less h l~V- lant multimedia informqh~n by separating the i~vnlllalio . into primary and secondary layers through the use of a plv~al,l model to .-.;.~;...;,~ the bandwidth ~ ;v~S. In such a system each layer will have its v~n set of ~&la.. cters that are important p~l~o~l~hically, ho.._._., the sec~d~ry layer will not vary as much as the primary layer.
What is meant by a program model refers to psychographic parameters vithin the mul~ clia system, that is l,al~ete.~ that relate to an individual's 15sensory ~ccptions when enco~te~ g multimedia infonnation. These pa~te ~ Cv~ ~ a set of unique and c - -;ctent elements for a ~ ~ular dass of ml~ltimedia ~ h~n In accordance wit-h the ~rc5e~ tion, its multimedia informqh~n is separated into dif~cle~.l layers in a~ da.lce with the ~ro~sl~u model. T~c lcfo~c, by way of c~k, in the inct5-nce of video images, 2() the fole~oulld and l,acLglvund ~.. I;~.. ~I;Qn might be divided into di~len-layers. ~ rly, in the case of audio inf rm~hon~ the news inform~h~n, ~ _all.el fQrm~hon, or the like may be one layer ~h_leas the bac~jlvu~ music may be the other layer. In the case of cou~ns, the fol~.vul,d may be te~t ~ccocj~e~l with coupon offer. The b~c~l~,ulld may be a layer image or the lil~e.
25In the present invention, these layers will be divided into primary and secondary layers in accorda.~ce with the information's i.l~l,v. ~..ce relative to the l,ro 1 ~l model. The most i. l~l k.nt information is i~entified and enhance~i toprovide the best quality inform~hon to the receiver of the multimedia information.

In the preferred embodiment, the primary layers will be enhanced in such a way to provide a perceived improvement in quality of the multimedia information presented. In one embodiment the secondary layers are presented that may or may not be enhanced. Thereby the important information or the S primary layers that are to be tl,.. ~.. ~itt~-l can be identified and sele~ rely enl~ce~1 in accordance with the ~reseut in~/cntion.
In ~ ition~ the primary layers generally can be enh~nceA through critical psycho~,la~ ic parameters take the form of ~p~ti~1, color, audio, and te~polal variables that occur in the primary or seconda~y layers.
In a ~~ ;r -.c ûetwo~k it is illl~. ~l that the multimedia infonnqffon that is produced, I~ ted and r~i~ed is enh~r~A in some manner. This is neccs~l~ to ensure that high ~idclilr, high quality il~ro~ l Q-~is ~r~ted to the viewer. Thefefore, it will be possible to bring a ~ pel;o.
I)rc ~ t into the ret~ ~ L It is known, for ~ le, it has been possible to provide video i.-fo.~ n over the telephone lines. H~ " it has been a problem sending high quality video ii~r.. ~ due to the bandwidth re.luil~nents that are needed to provide such high quality video ;..ro~ ;on.
The ~:e~~t h~ iG~ iS .lil~c~d tonralds a method and al,l)alalus for l,lo~.lillg a co..~ c and ~acl~i-,g system. To more ful~ ~k~in such a method and apparatus, refer now to rigurcs 2-5 which sh~ws a block diagram of a general c~l~~ ent and block dia~allls of ~.:r~ e~l~li.llents of the overall system ~r~hi~<~lure for an enhqnre~ tc.~t~e mnl~nedia system for a ;~ns network. The overall arch;lc~ c would be connected to a telcphone neh~lk or thc like so as to readily access the ~ iCcion lines lo~atcd therein.
Figure 2 is a block diagram of the overall system archite~h~re 40 for an enh~.~ccA il~te~ ~ive multimedia system. The overall architecture 40 would be cc,mlc~l. d to a telephone n~ k or the like so as to readily access the ;on lines l~lcd therei'n. Referring now to Figure 2, the system architecture 40 C~ Jli~S an interactive multimedia mastering system (IMM) 42 -, WO 96/278~3 CA 02214711 1997-09-04 PCTAUS96/03137 which receives yrG~dlll source material. The IM~ system provides information from the telephone network to a multimedia call procc~;..g system (MCPS) 44 and an ~q,l~Yiliqry system 46. The multimedia call proceCcinE system 44 will provide and receive information from int~acli~e multirnedia devices (IMDs) 52. The S MCPS 44 is also cvu~ to a p~L~ter 29 to provide the couyons. In this fashion, a system could be con~ul~d and no sper-iql equipment is required. All that is nccessary is the telephone to select c~,up~us. Therearler, MCPS can create 1 direct mail for the .;.:~lo-~er, which can inr.lude the unique co~ponC
encode~l with idc"~i~ier inf~nnqhon which has been selected by the cl~ct.mer utilizing the tPlepl~one. The ~Iru~.lulc of the IMDs 52 can take on many diL~ IC~.t forms dependent upon how much intell;6. ~ce is located in an IMD 52 relative to the syctem ou~h~ ie 40.
The ~ystem &l~ki~cv~ 40 provides l~ro~,l~ material which will enh-nc~
thc interactinty of inf~ nqhon that is l~ lc.1 along the telephone n~ .L
Ac~ol.lin~, what the system architecture 40 1~)r~S-nt~5, in fact, is an additional nch.J~l~ which would ~ from the ~lG~ alll source which would also be part of the ~ telephone system. The system alck;~e~ re 40 will then be utilized to provide for çnhqn.~ multimedia information through psychographicmq~irl~lqtions or other ~nl~ c~ el~ls to the ~I~,ms to provide for a C~ which can be issued and l~._c~.i in a ~,cu;_l~, of ways. The system 40 as above-~,.li.~ned includes an IMM 42 that provides much of the ol,t;~ hon of the ~ro~,,~ source n--qPnql for pr~cent-qhon to MCPS 44.
Refc,~ , now to Figure 2A, a general embodiment of an architecture 100 for a hotel is shown that includes a multimedia ~roce-~in~ system (MPS) 102 which is c.,u~l~ ' to receive information from and transmit information to a video control system 104, an r ~ ~ _ nt c~-p.-tcr 106, a service opel a~ .s platform SOP
107, and a telephony ~wil4hillg system 108. The MPS 100 is also C~U1JIed to an interactive multimedia ~1ecoder (IMD) 110, a CD/I device 112, a laser disk 117, video camera 121, c~ p~- l disk (CD) player 125, pelsol,al computer (PC) 119, video camera recorder (VCR) 123, a printer 129 and other devices 114. In this WO 96/278~3 CA 0 2 2 14 7 1 1 19 9 7 - O 9 - O 4 PCT/US96103 137 system each of these devices can be utilized to provide ~lp~t~ble multimedia information. For example, a comr~ct disk player 125 can be utilized to jump to difl~ rent places to provide multimedia information. It could be utilized in conjunction with an IMD to augment the fixed media with ~teldclivG material (~pd~t~ble video source) material.
The cable feed line of the system 100 in turn is c-,-")lcd to the video controlsystem 104. The ~rc ,,~nt c~ y..ter 106 and the SOP 107 are also dile~
coupled to the telephone ~wil~ g system 108 via line 120. The telephone ~wi~hillg system 108 is capable of sending and r~cc;Yi~g outside calls. The video control system 104 is capable of 5~-- t;. g and recc.~g a remote signal from a cable system, I<lcc ~--.. u~;~, . systcm or the lilce.
Another yG LG~ of the i~ n is an interactive voice ~ system 111. This system il~rlntes a ~l~h~ne 113 which cc--.~c~ to the telephony switching 108 via telephone links. The tele~llone 113 also could ir~ v~e a credit card slot. There is also included within the system 111, a remote control 900 which will be descnbed in detail later and a tel~ ;o.. 115 which is ~ c~t to thecable 116.
In this SIJC- - I ;G eml~odh.lc ~,t, the m.~ ,rocc ~ ystem (MPS) 102 lec. ;~_s y.ogl~ source ~atelial from the SOP 107 and from the control system 104. The MPS can also Op-,lalC, an ~le.dcli._ voice le~o~ ~lG~
lepen~e~tly or int~;laled into other interactive multimedia y:O~aluS.
The SOP 107 is utili~d for lecci~ g facsimile and voice me~C~ges. The SOP 107 can also be utilized in cc.~ljul,,lion with pagers and the like to relaymcssages. By linlring the -~ nt cc,~n~ul~ r 106 to MPS 102 messages can be displayed on a monitor within the guest room. In addition, fa~ces can be displayed on the tel-,~i;.ion and could be fo.n,alded to other locations.
A master multimedia y~eis;~ center (MPC) 109 is also coupled to the closed cable system 100 via co..-~c~;on to the MPS 102. The MPC 109 is coupled to a plurality of closed cable systems to provide enhanced int-,..._li~il~ thereto.
A critical portion of the system 100 is the telephone ~wilching system 108 g ' W O 96/278~3 CA 02214711 1997-09-04 PCTrUS96/03137 interface. Through the use of this archite~ re the s~vitching system 108 can be controlled to provide the a~,ro~,liate information to the user. Through the use of the interface devices (IMD 110, CDlI 112 and the other device 114) and the MPS 102, the ,wil~ g system 108 can be controlled in such a manner that the user doesn't have to remember a telephone number to obtain the desired information. This control can be ~ccc.mrlished through either a digital link that is dile~ interfaced to the telephone awilclling system 108 or through an analog link where on}y a normal phone con ~c~,l;o-~ to the system. Through either of the L~ S an em~lqh~n of the cl~tc.mer, honc would be undert. ken.
In a typical ~ple, a call is made by the user to order a c.. ~o.- The MPS 102 places call to the room through control of the s3rstem 108. The room telephone will ring and the MPS 102 will send a me~a~e to the awil~ g system 108 that the customer would lilce to access a ~,~.. Ii ,.,lar coupon to make r~,valions. All of these ac,L~it;es are done l~ c,.lLb to the user.
The MPS 102 will provide and rc~;._; ~rc - .. ~ I :o-~ relating to the couplers from and to interface devices 110, 112, and 114. The interface de~;ces 110, 112,and 114 are in the hotel f~t.ilities co--.-~ct~l either to the hotel video cable system through use of the vi't~udio o..~ t~ or connected via digital links from interface d~,~i~s 110, 112 and 114 in each guest's room.
Refe~ now to Figure 3 what is shown is the prefel.ed embodiment of a MPS 102. The MPS 102 co~l,.~s a diallll,uled cvl..puLng archi~ ,c. The d~~ ed CV1~ ~& ar~ c i~,lv~s a master node 200 that has, in this case, threc server nodes 204, 206, and 208 for the IMD, CD/I and the other dc~iccs r~,L~e~r. The other dcv;ccs that could be ~>.,~lcd to MPS 102 are,for e~cample, but not limitef1 to video games, a CD ROM device, a ~craonal cv~ uler~ or a spe~qlty device such as a trqn~lqtor or ~ming device such as a video slot m~chine or the like.
Each of the server nodes 204, 206 and 208 have client nodes 210, 212, 214, 216, and 218 co-...ccle-l to the rc~e~ re intcra~ c devices. Attached to each of the clients nodes 210, 212, 214,216, and 218 are ports 220. When connected ~ WO 961218~3 CA 02214711 1997-09-04 PCTrUS96/03137 via the f ' ;~ , networks or the MPC 109 (Figure 2a) and then on to connection to the inte,a-ilive devices 110, 112, and 114 (Figure 2) which has its own yroce~ g storage and computing structure the entire network ean be operated as a massive di~ lJuled colllyu~ g e~viro~ ent. This system could be operated S using a voice rcsyo~ system in the server or elient modes for which ports ~o ~r~e.lt telephone ports eonneeted to the cv~ nir~ffons neL..~,~k.
This~ irv~entsharesalldim- ~i,;vl,sofcv ~uli~g~storage,tr~n~ ;Qn and pel;yhe al ~eso..l~s (printing, product ordering, m~ilin~ funcliv~s, ete.).
This type of cv~yuli~ archite~t~re would inrl-~de ~ ic port alloeation and would inr11 ~le ineremental failure ehalachli~lics to allow for rvl,~-cl~e~ of the MPS 102.
In r'~ through the use of this interaetive system 100 of the y.CK~t liv~ a multiplieity of .l;~E~.ent interactive de..c~s ean be utilized and no mo~;r; ~;o~ to the deviee need be made to allow for 1~;c~' use within the ~srstem Accold;n~ the link 1~ n the MPS 102 and the interactive ~
can be a serial lin~, a CD/I link, a cable link such as etl~e,net or telephone cc~ e~ via a simple i~o~d relay controi link.
In a first more ~e .;r;~ embv lh. e ,.t shown in Figure 4, the mul~ edia ~r~ g system (MPS) 102 ~ s p. o~ ~ source material from the ~, ~,;ces op~ ,alio~ pl~tf rm (SOP) 106' and from a pay video control system 104'. The conLIvl system 104' can begin cv.,l~-- o~de~ g.
The SOP 106' is utilized for r~i~ g COVpQnC The SOP 106' can also be utilized in conj--~cLion with pagers and the like to relay messages. By linlrin~ the SOP 106' to MPS 102 a CUUP~ can be displayed on a monitor within the guest room or print a cou~on at the printer 129.
The multimedia ~r~ ~ .g system 102 wiil provide and rec~ information relating to the c~wy~S from to hlLe,~Li~e devices 110' and 112'. The ;lltc,~li~edevices 110' and 112' will be located in the hotel f~ilities connecte~i either to the hotel video cable system through use of the video/audio outputs or connected viadigital links from interactive devices 110' and 112' in each guest's room.

W O96/278~3 CA 02214711 1997-09-04 PCTrUS96103137 In a second more specific embodiment shown in Figure 5 the architecture is similar except that there is an IMD 110 in each guest room. The IMD 110 can also be used within an interactive voice response system 119 to provide a more complete i~tela.~ e system. In this embodiment, the IMDs 110" can be utilized to prv~ride the i. ter~livil~ for each room. The structure of the IMDs 110" willbe de~ lil,ed in detail later in this ~ec-ific~tion.
The IMDs 110 can take on many diL~elent forms dependent upon how much inte11i~ence is ~oc~te~ in an IMD 110 relative to the system architer.tnre 100. The system a..~1.;le~ ie 100 shown in .liLrele~t ~e~l~ in Figures 2-5 provides program material which will enh~nt,e the i~ aCtivil~ of infarm~hon on the cv.~vn that is h .r~ e-1 along the video n~,~vv,}. Accor.li~ly, what the ystem architecture 100 le~;~nts, in fact, is an s~ itional ~_tWVl~ which would r~;~_ infarm~ n from the ~,v~ source which would also be part of the ; dosed cable ~ystem. The ~tem ars1i;~1.,i e 100 will then be ~1t 1i7ed to prvvide for er~ ~d mulh~s ;.................. r -.. ~ t-- through psychc~lapl~c hQ~ or other enhancements to the coupons.
Within each of the IMDs 110 of the system 100 is an o~t;.~;,At;
ter-hn;que for enhancing the quality of the multimedia information that is pl esel~t To more ~ lly de~. ' s this o~,t; .;~t;on teçl~n;T~e, refer now to Figure 6 which is a block dia~ of an o~l;~.. ;--t;on method in accordance with the present ,u~,enlioll. This ~1~ ;~ ~ t~k..; l~-~ has been ~1FS ib~d in detail in U.S. Patent Appl P~- ~ ;o-~ Number 07/976,941, elililled, "Method for the Production and Tl~ of F.nh~ l Multimedia Information~. having a filing date of November 16, 1992, assigned to the assignee in the present il~/G~LVII, and that patent appli~Lo.- is inco.~v.~ted by ~efele.. ce in this applicalioll. The following pal~jla~>hs along with the - ~ c ~p~nying figures will provide the details regard~g the o~ hon method and hv~ it will be used advantageously to provide an enl~nce~l interactive multimedia system.
The ~ OSe of the IMD 110 is to provide m~lul.J interactivity while at the same time providing maximum retention of the t~rG~ model of the coupon.

. W O 96/278~3 CA 02214711 1997-09-04 PCTrUS96/03137 It is also inl~)ol ktnt that there be minimum transit time for the interactivity while the information within the coul~on has maximum replication. There~orc, it is veTi~po. ~lle that the 1'~ GOIaln model psychographic parameters be well dcselil,cdFor e~ample, the sp~qt~-q-l, color, tcml~olaL audio response, mateAal concept, S conlcnlioll ~clc~liùll all should be very well der ,il)ed and defined in the plo2;l~ model of the cou~on.
Rerc;lling again now to Figure 6 what is sho~-vn is a first embodiment of a flow chart for ~rovid~g an enl~qnr~l int~,acl;~c multimedia CuupOII that utilizes the p.i~ci~lcs of the p,esent h~ nlioll. The flow chart 300 co~p~s the steps of l,ro.idiug a program model of the co--~o-- to a ~al~lol. The ~cpa~ato~ 302 will divide the ;.~r..,...~ ,. of the Cu~ into primary and ser~nllqry layers of ~le, ~: t*e m~ q inforr~qt~n For e~ample, the primaTy layer may be the te~ct on the coupon. The ~e~ n~lq~ layer on the other hand may be the logo ;..r..~ on the coupon. The sc~l.,lion is ~--t~ t;c and can be ~ ~cr.. l-li~hed in a var;cLr of ways. For ~ ,p2e, the layers can be ~l~al.. ted by productionso..lccs. In~olhel; l~le~ alaLi~-canbe~ mrl~ edthrough Icey c4d;..~ the layers. In yet a third e~p!e, the layers can be sp~h~11y sc~a~ d or s~l,alatcd by the ValivuS colors. Finally, layers of information could be Se~a~atCd by a Ç~kli~g p:occ~~.
The primary layers are provided to the compression generation block 304.
There are a variety of ways that the multimedia data can be changed or generatedto use less bandwidth. For ~ , cv~re- ;on algo~iLl~ms or their equivalents could be utilized to reduce the bandwidth used. In addition generators, such as in a tone geneMtor system, could be utilized to reduce the bandwidth required.
Finally, key coding ~l~ms could be utilized to reduce bandwidth use. Such systems will be d;~ eA in more detail later in the ~eciLication.
In this embodiment, the primary layer of the coupon is provided to an enColler where the primary layer of the cùu~n is p.~ared for tr~n~mi~ion via step 308. Thereafter the primary layer of the CO.,p~l. is ~1eco...~les:,ed via step 110. The primary layer of the coupon is then decoded and mixed with the ~ W 0 96/27813 CA 02214711 1997-09-04 PCTrUS96103137 secondary layer of the C~JUPOn via step 312 to provide an enhanced interactive multimedia image of the cuu~on to the printer.
~ ;imilsrly, the seCon~qTy layer of the cu..l~on is co~")ressed via step 314, encoAeA (via step 316) and then hransmitted via step 318 and to Aec~....press and S mix, via step 310. The two signals (primary and secondary) are then sent to the printer via step 312.
In this embodiment, for ~ ~plc, for the ophmi7shon of a coul,ou~ the primary layer can be the fole~uuJ-d image, the seCon~qry layer can be a backgroulld image. Through the use of this type of ophmi7qt~ technique mulli~c~ia informqtiQn can be ~ s. r~ l while at the same time utilizing ~- 6. il; -. 1~ less bandwidth.
To more fully understand this î~l~.lc refer now to the following ;o . In a typical interactive ml~lhmedia s,vstem the il,[c,lm~Lion is all sent along one layer. The information that can then be tran.~ J is l; .;t~d by the bandwidth of that layer.
In the prior art, the interac~ve m~ lia infn~m-q-hor that could be 11_-. --.;l~ A along typical nch ~lu or l~ r~ paths that are very limi~f~A
be~..se, for e~qtnrle, in the case of video images the bandwidth is not adequateto provide a high quality image to a ~ r.
Hence, in the p.~.. l h.. nliul" by separating the mul~e.lia informq-hon into l,li~aly and secondary layers and Ihercaltcr co~l,r~;~g the more im~ol ~nt informqt~n utilizing well known ~l~;O_ alg,c,lill~s, a system is desclil,ed that can produce an enhanced coupon that easily be tr-q-n~mitteA over ~ I;..g ~eh. Jl~
To more fully dcselil,c the psychographic enl~Pr~ement feature of the present il.~_~llion refer now to Figure 7 which shown the various ~ossll,ilities from a IJ81 L. ular 1~ O~a.~l modeL The ~ Ul model is provided to the separator 302 of the multimedia system.
P~h~l~hic enhqncçnnents are critical to t_e ~pro.cment in interactive multimedia trqncmi~c;on and reception enh-q-nc~ments in the context of the -1~

, W0 96/27813 CA 02214711 1997-09-04 PCTrUS96/~3137 present application is information that is not transmitted but operates on, o~)el atcs in conjunction with, or operates as a supplement to transmitted multimedia information. There are three separate categories that will be desc~il,cd that relate to psychographic enh~ncements.
S The first catego.~ will be de3c.il,ed as a cross correlation l,~ cn the informq~on that is bcing tr~n-cmit~ecl and being enh-q-"ce~l due to the presence of information that is not l~ led. Dithering of image is an eA~ JIe of this in that dithering masks allif~l~ of images that are present and that imprv~es the image quality. This type of system does not remove the al lif _b but actually just masks i~e.f~liv~. A se~n~l ~,~pl~ in the audio arena where secondary audio l.lat~lials such as a sound of an ocean or the like which might mask ~;ob'-mc in the audio quality of the pr;mary sound (voice, music or the like).
The seco ~ t~c.. ~ is where the signal is actual}y changed willlv~l the use of any control signal; for cA~p~e~ through inte~olalion or some other te~hn;1ue.The typical ~ le of that i_ a ~.~hic e~q~ er in which cel L~in frequencies are ~.nl-~ ,.r~l depending on the range of the l,al ~ular device. Another example ofthe sccond category is to freq -~n~y or ~mrlit~-le co.~ ~s a ce~lain signal so as to fullLer enhqnce the fie~ ;cs that are being 1. ~ It is also known to use ~ ,..s filters to sharpen or provide certain information that will actually modify the signal willn~l controlling it per se.
Finally, the third c~tcgo.~ is using the primary and secondary information to drive the other geneldto.~ that might be l~r~ut within the multimedia system.This can be utilized to either cnhqnre the multimedia information or enh-q-n~e the pr~a.,l model of t_e cv.~pv~
As is seen in Figure 7, the primary multimedia information layer can be CG.~lCS~d to reduce the bandwidth utilizing well known algolill.ms. It is also seen that the signal can be replaced by a generator that is res~vn~i~G to the primary/secondary layers ci~nqlc Finally, a key code could be used to cause information to be provided from a look-up table or the like.

~ W 0 96/278~3 CA 02214711 1997-09-04 PCT~US96103137 Although all of the above methods provide advantages in accordance with the present invcntion, key coding has some additional non-obvious advantages when utilized in the optimi7~hon system of the present invention. In the following paragraphs the use of various key coding systems will be desc~ibcd S generally along with their attendant advantages.
Typically, when looking at an intela~,ti._ multimedia information signal there are several components of that infnrn~hon The first component is the data or the mnlt~media inform~hon itseLf that is being co~ ~l. The second component is re~e.led to as l,lo~a~ model dr~mirs That is the changes that occur in the inle,~a~iL~_ mnltimedia infnrm~qt on due to for ~ a fade that allows for a transition from one scene in the g~à~ a or video image to another CO.I~_~ ely, if you want to wipe away an image there is ;..f~.-. .qtion ~ te.
with the ml~ltimedia data that would call out for that lld~sili;>n to change ~rr;r;.~
Finally, the third cdtego.~ of i~ t;~_ m~ltimetliq infonn-t on is what will be ref~.le~ to in ~s s~ ;on which will allow a ~al~ular device or system to go from one cat~go.~ to qnother. In a typical i~ m~lhmedia infc-rmqtion system all this infQrmqt on is required to -q-~leTIqtely ~ slnil such information.
In its ai~ est form, a key has an ;~ I;r;~ble code which .l;rl~tes the cc.. ~ c on the other side of the device. The clealcal eY-.nple of such a keying system would be the very simple dual tone mulff-frequency (DTMF) signal. This type of signal can be used in the t~ t;ons area to provide keying for low bandwidth p.ot,ocol. These keys would then c~mm~nd a code table on the side of the n- twc,lk to provide certain information about the multimedia information to be displayed without ~e~luh i~g actual tr~n~mi~;on of the multimedia inform~-1ion A more spc~ :r;c version of this type of key coding is what will be referred to in this sl,ec:lic~hon as control information keying. What is meant by controlled information keying is where a key code is utilized to access particular -1~

~ W O 96/278~3 CA 02214711 1997-09-04 PCTrUS96/03137 types of c~mmq-nds which can then be used to control other items on the other side of the n- Iwol}.
Such a table would then be utilized to access a Ccl ~LI set of multimedia information in the network. A final version of key coding will be called progl d~n S brqnrhing keying is des~libed by each of the keys re~rese~lting a certain branch ;r;ca~ion. Thus in this type of key coding the key is cross rer~renced to a particular branch of the inte,dctivc mull;."cdia ~iGg~ where each of the branches allows plur.,lity of fi~nc~r~nc or cmnmqn lc to be ~~~e~ in order to replicate the p:o~a~ model of the cou~
The h~ lant fealure that is provided by all of these types of keying coding all~E,e~ ntc is that il~ on already ~ ~lt on the l.elwv~k can be utilized. Tl~ ore, the ~r~ ~ power inherent in the l.clwull~ or the systein being ~ce.s~eA can be utilized rather than having to have to provide that powerwithin the ~! -~ t ---- system it~celf.
It is also important to develop means to il.. p.o._ the h -;on quality of the multimedia ;.lû- . .gl ~ ~, for e~ample, the informq1i~ n may be lla--A., jl~.1 utili~ng a typical lla~ O algolill~ with s~qr~ q-rd cou~~ ;cn file data L~ ~l p.otocols. The h~1e.a~1;._ multimedia informqtion could also utilize speciqli7~A ~ro~ols that are ol)t;...;~e.l for the ps~ ular interactive multimedia information that is to be t~ eA In so doing the algo~ for the CC)~I~pl. ;on al~,<,~ill.lu can be in1~ 1y lnqtn ed with the l~ c;on al&o~ to provide the ~igh~st quality informqti~n with the m&~
interaclin1y with the mi l...,lu~ O~I line.
Rcre~ ; now to Figure 8, what is shown is a flow chart that shows the cool,elaLo.. of the tr-q-nnni-Cc;c!n al6o,i~ wit_ the complessi~n algorithm toproduce a high quality multimedia image for a coul~on. The flow chart cc~
providing a ~-G~I model in w_ich the primary and secondary layers are separated via step 402. The primary layer is compressed and enco~1eA via steps 404 and 406.

' W 0 961278~3 CA 02214711 1997-09-04 PCTrUS96/03137 A control element via step 410 is utilized to control a compression matrix and a tr~n-cmie-cion matrix. These two matrices comprise a plurality of cc~ rcsshu algo~ and tr~ncmi~cion alg~ rc~c~L~e}y that are i~tcla~ c}y controlled such that as the various algolilhms are detected the S quality of the m~llhmedia inform~hon and the speed of the tr~n-e-mie-~ion are interactively ~let~ ed.
The quality of the information could be determined manually or through the use of some control c~.;uill~. It should be understood that these same matrices could also be used on the secondary layer. It was not shown or describcd for purposes of clarity and ei~nrli~Aty.
R--f,~ . ~ ;aE, now to Figure 9 what is shawn is a block r~resc..~lion of a matri~c of COD~yl~ ;on al~o.ilh,.l with 1~ al~ that could be utilized in ~ rdancc with the ~.csent ill~cnLon. The circles 502 ~ligred in the vertical dil~tion are the cc,~r~-~;on algo. i~ c The rec~ es 504 ~lign~rl in the horizontal .li~ ion are the 1,~ al~ ........... c For .~ the c~ ;on algo, ;lh~ ..c could be JPEG, a generatorwith MIDI, and a key for a weather map bac~lvund. ~ rly, the t~ U
algc .i~ .s could be c,p~ for JPEG, data c~ yre~;on for MIDI, or DTMF
for Iccy 1~ - ou type al~,c,.ilh~s. To pravide the highest quality mnltimedia informqtion while at the same ti_e utilizing ~i~u.. l bandwidth the .liLlelc.lt alRc,.ill....g can be sele ~e ~ in an inte.L~ manner.
Hence, a first C0..~1~1 ~ ;Gn alg~,.ill~ could be s~l~t~ d along with the first h,--- ~...;--:-~n alg,o,ill~. The multimedia in~c - ...~1i. n is ~c~,i .ed either for image or audio quality than a second c~ plc~i;on al~,~,.ill,.,l is selecte~ Th 2~ multimedia inform~t~ n is reviewed and if the quality is not ?-cel~table then a secon~ OIl algo.ilL... is select~A The quality of the information is r~ _l This l,.occss is rCpcatc~l until the hi~ or desired quality multimedia inform~tion and i~t_~a~,livil~ speed are provided.
The multimedia information derived from the c.,~.lprcssi~"~/tr~ncmi~cion algo,ill~ls can be analog or digital in nature. H~ c., in a digital signal there -1~

, ~ W O 96/2~8~3 CA 02214711 1997-09-04 PCTrUS96/03137 are certain other features that can be taken to advantage that can be utilized in accordance with the present ill~,elltion.
It is known that digital data informaffon is typically sent in a file which specifies certain parameters of that data and the data informaffon itself and within the data informaffon itself is informaffon which may not change for a certain set of files. In the case of an image file, the header inform~hon may specify the di lle~i~,~s, pi~cel depth, and certain other fealu,es of the pal licular image. This file may. take up a much as twenty percent of the data file.
Cc,.~ c3y, in a file such as text file which com~ ,e, a plurality of text i~lo~ h~n, the header may include ~ .. 1 i~u~ t;on related informqholl and chara~ hcs of that parffcular file. In both of the above ~ nhQned lcs, the headcr infnnn~hi~n may not Ç)'-~b-- through the use of the ~~ t ~n method the amount of i~c.~ - may be si~ re l -c~l over ffme.
Hence, in the ca_e of the image file, the header could be sent first with no co~r~ ;~n or with k~ ss data C~ n as the secondary file l,e~-~ it will always le..~a~in the same. The data file itself can then be c~.n~lcs3ed down to its ~qller size.
Another method for enhsnrin~ the psychcs~l~ylLc parameters ~ to provide 2l) some form of error det~ .. and ~ lj--sl--.cnl. As has been menli~.. ed before the ~letechQn and adju~l~enl can be ~ hed via i~ sti~n of the error. An alle~nah~. method of error co,l~l~r is through an error cc..l~chon/h ~ iC~ n algc,~ . What ic meant by this, is relating the l~ to the compressio to enh~nce il le.a. Iivily.
In this type of system before the file is sent the base file is co~ es~d and then d&co...pres~d. This dcc~ .re~d file is called an e~Ts-n~le~l cc,l.l~re~ed base file. The ~gr~l~' c~, I,re~d base file is then co..-p~ed to the original base file and an error file is then developed (the error file being the difference between the base file and the ~ s-n~ed compressed base file). The error file is colllpl es~ed and sent along with the conll)rcssed version of the base file down the ~ W O 96/278~3 CA 02214711 1997-09-04 PCTrUS96103137 line. These files are then combined and decol.l~ressed to provide an enhanced mage.
Refelliug now to Figures 10A and 10B, it is seen that a data file utilizing this technique could initially be separated into primaly and secondary layers. The primary layer of the cc,ul~on could be com~res;e:~ using a first cGIllpre~ion algo,ill.. ~, the header inform~on of the C.J.~ could be sent first along a first on path and the c~,,.ll)ressio,. signal could be sent along a second .. path.
Tl~e,~ole, the amount of storage ne~ess~ly for the file is significalllly re~ ed through s~ d:~ry co~r~i~,ll terhni1nes This inf rm~hrn can then be t.--.~--.;l~c-~ or stored across the ~t~.J~L rather than having to have all the inf~rm~ht~n stored wi~in a ya,L~ lar device within the oyl;...; ~h -~ system.
In the case of the co~ n 500, lefe~ , now to Figure 10C, the 500 in~ des a logo 510, test i.-r .. 5~ .. 512, bar code hlr~.lllalio~ 502 and 504.
In a ~ fe,l~.l embodiment, the co--~-- 500 would have e.,co'~' the~ h~
traclcing i~r~ o ~ in this emb~- -r~t, bar code 502. This c--~li. g allows deh~o.layllic info~l~lahon to be provided back to the system when the cou~on is utilized. In this way, additional products can be COOl~ te'l with the C~ O.l y." ~ ~ ~
In ~3.1;~ .. there is an anli~raud code 506 placed on the C~,u~.l to ensure that these c~lpon~ are not CO--.~If--~i~ In this e--.bo~l;.-.ent, the ~nliLaud code 506 is a bar code. H~ " one of ordinary skill in the art will readily rcco that either the h~c~iug informqh~ code 502 or the anliLaud code 506 could be a wide variety of types and their use would be within the spirit and scope of the present hl~ ion.
As is seen in Figure 10D, the header information 562, text date 564, logo data 566 and bar code control data 568 is ~lloc~te-l to certain portions of the memory. This information can be compressed in the ap~lo~liate manner to provide the enh~nce~l multimedia information.

Accordi~,gly, this system can be utilized effectively in a voice response system. Through the present invention a voice response can activate or operate in conjunction with a multimedia pl ~l ~ to provide a fully interact*e co.,ll-.unication system.
An i~ la.~t feature of the cuu~ ing system is vclirjillg the authenticity of the cou~,on. Figure 10E is a diagram of cv~~u verifier 600 in accordance withthe present i ~ liGu. The verifier Col~ ~s, a scanner 602 for sc~nning the bar code and the lilce and a ~lo teclor 604 for detectirlg the information.
Rcfe,lillg now to Figure 10F is a flow chart of the opelalio~l of the verifier 600. As has been above mç~ e.l the co~ qn is sc~cd, via step 652. The delec or then ~t~nircs if the co..~.. is authentic, via step 654. If the C~)u~
iS ~..tl~ then the tracking data is recorded, via step 656. The coul~.l is then det~-...;ncd to be a-lho~l~, via step 658, prefelably by a green light on the ~-~t~lor. If, on the hand, the CO~ n is not ~ c-.~ via step 654, a bad c.,ul~on indi~atol is provided, via step 660, r~efe.al/ly by a red light on the ~loteclor 602.
ANTIFRAUD DETECIION
Antifraud dct~ can be p~ ed in a ~alicl~ of ways. One c ~ e is shown by the flow chart in Figure 10G. First, a COupOIl i~lentifier is specified by the system via step 670 and a l~ --, number of predetermined digits is sP l~le~1 by the system via step 671. Tll~ rearler, the random number is logged in a ~l~t~b~ce within the MCPS along with the c~ cs~,-.~ing cou~,on idenliCier and other inform~1;on to create a co- ~,.u record, via step 672. Next, elements of the c~uyo~ record arc either genelated and embe~ e~l in the coupv~. or given to the c~lct. mer via audio, graphics or by some similar method via step 674. The ulu inf~rm~hon provided is the code (i.e. the random number or the ID, dependent upon the user). The above steps describe the inih~li7~tion for the antifraud dete~l;n.. system.
Next data embedded vithin the c~uyon or given to the customer is entered into the verification system, i.e. MPS, KIOSK or otherwise via step 676. The coupon is then read by the bar code reader, entered on a keypad, or by a voice W 0 96/278~3 CA 02214711 1997-09-04 PCTrUS96/03137 response system via step 678. The relevant elements of coui~on records are readyfor verification. Nelct, the Cvu~vll is cross referenced in the cc.uyon data base for corresponding CO~,Ol~ record via step 680. If there is no record then it is not a valid coupon via step 682. If there is a record, then it must be determined if the cvu~on has been used before via step 684. If it has been used, then fraud i ~etecte-l and al,pl O~l iate action is taken via step 686. If the cou~on has not been used then the system changes Cuupv~l from nn~ to used via step 688. Then infnrm-q-t~on for v-q~ lq~ng coul~v.l is sent via step 690.
One of ordil~alr slcill in the art will rccc~ e that the cvu~, cou~on ~el;~ier and the allli~aud .l~tec~on system are not limite~ to those shown in the L6.,les. In -q~ n it should be ~ that the ~l~c~-n of the CvupO.
inf~rmq~- could be changcd and that would be within the spi;rit and scope of the present in~enliv_.
The ~r~_nt i~ lio has been ~l;~ A in terms of Cv~u~lC~_ g the primary layer or layer and by CV~ l~illg and 1~ that primary layer in a pall~ular way the interactivity of the system is enhqnr~e~ It should be ulld~ lood that it may be equally i..l~V~ to enhqnce se~ qry layers to produce the same effect.
Tl~erefvre, it may be ~. IanI to enh-q-~c~ the secondary layer, it may be V~ lant to enh-q~ the primary layer or it may be ill~JVl lant to enhq-nr-e both.Therefore, the present iu._nLon through the use of cv~npr~;G~. and trq-ncm;~;on al~o~ us and through the ~a~chO~,laphic enh-q-nr~ment of the p~o~a..l model can enhqnee inte~a~ livily of a multimedia system.
It should also be understood that the function of the co~ re;,sion and tr-q-ncmic~;on algo.illllus can also be done t_rough other means; for e~a~ JIc~ a signal gene.atol could be used to provide the same information. That is, a signal generator res~vns;._ to a ~a~ ,ular layer or layer of information could be utilized to provide that information or some level of information that is re~,rc~ntative of that layer. For example, a tone generator res~,onai~e to a signal from th ~ W O 96/278~3 CA 02214711 1997-09-04 PCT/US96/03137 secondary layer to provide the tone that would be rel)rcsentative of that secondary layer.
Cc~el~ly, some type of graphics generator could be utilized to respond to that same type of signal to provide a certain type of graphic image or logo of S the C~JU~OI1. Finally, it should also be understood that the ~rcho~laphic parameters can be adju~l~d by human opelalor or in the alternative can be adjusted or modified by an autc.m~t~& means.
As has been before mentioned, it also is very important in this system ar~h;le~ .e to have an inl~ .a~ r. multimedia device 110 which will allow for the recei~t of high quality multimedia inform~ n for the cvu~v,. from the system c~ -e. The IMDs 110 can bc either 1OeA~e~ in the facility in the b~Pment or are utilized with each of the t~ .Oion monitors within the hotel or hospital room to provide çnl~..r~ audio, video and graphic h,l~ hon within the CO~l~ 'A ~ ;O~S ~t. ~ l}.
Figure 11 is a ~refe~ -.ent of an i~tela. Ii.~ multimedia ~le~er (IMD) 110. The IMD 110 cv l,li~s several co ~r -nts. The cable or telephone line is ~.plcA to a mulli.~ modem 1102.

In a ~.~fe~l~d ~ ;...ent, the IMD 110 will be utilized with a ~,i. tcr to ha~ ~ il and ~ multimedia inf~nPt~on. Th~ ~rorc through the use of the ~Ds in the system a ful}y interacL._ system for l,rovi.ii. g c~Yt o ~c is provided.
Figure 1LA shows an IMD 110' which has an output to a piinter 507 and a telephone h~ c.t S09. The printer 507 then is utilized to print cvupo~s ~wpo~ _ to the telephone handset.
Figure 11B shows a f~rcimjl~ 700 which could be coupled to print the COhpOll. The f~rcimile 700 may in some in~ces be the plcrc~d method for l ccch~ing COu~)nS for 1,~ e-~s Another critical feature of the IMD 110 is to have a remote control that will work in conjunction with the television or other display to provide enh~nced multimedia information. To more fully explain this feature refer now to Figure -2~

~ WO96/278.~3 CA 02214711 1997-09-04 PCT/US96/03137 12. The remote control 900 looks much like a telephone keypad. It has the numerals (0-9) and symbols (*-#) that are part of an ordinary telephone keypad It includes an enter key 902 that is typically utilized to change information orchange chqnnçl~ in the case of a television set. The control 900 would also S include a volume key 904 and a ch~nnel or memory select key 906, a connect key 908, a telephone call key 909 and a multimedia toggle button 910. The telephone call key 909 is utilized to place a call to a ~e .;~-~te~ telephone number or to a l~umber ~c~:~t<~ with the mulli...c.iia il~fo~nqti~ being viewed. The remote control 900 also indu l~s a keys 911, 913, 915 t_at will control the fast folward, re~el~, and slow motion of a video device. A sper;ql key 914 is provided to provide a C'J~ ' at a p~intel or the like.
The remote control 900 could also include a credit card slot 912. This credit card slot 912 would be utilized by the viewer to allow for the i~c~uqnce of the CV!'~'' dil_l~ while vi~ 5 the television screen. The credit card slot 912 could also be utilized as an indicalor that a c~ ~ room is being oc~ ~ic.l by a particular person. This ;" l~;o.~ would preclude the need for a sepa,~.te iL~..Ili~g of the ~c,l~,~aL~l user information for billing inform-q~ n Finally, the control 900 includes spe~;ql effect keys 916, for ~ ,le, for allv~ing for the blvw~ g of a multimedia .l~eclc.r while simultaneously dis~la~ing a picture in the picture of the .,.. lleJ.t br~dc-q-~t TV channel. The remote control 900 can o~ le in an emulated keystroke mode in which ~r~g one key may be utilized to çm~ qte a coml~i.,alion of }_~ o?-r-s. In addition a call button may be provided which would allow for s~n~lin~ valid .~ b_rs to anoll~er location. The remote control 900 also has the capability of emulating other remote controls.
For e-Aample, through the MPS .liLf~rellt ~pes of signals can be mapped with theremote control. The MPS provides the tr-q-nClqtion of the signals of a CD/I device for cAal~lple.
The remotc control 900 could utilize a radio frequency signal or audio signal to h~t_lacl with the recc;~er and/or IMD 110 for the control of the IMD
110, control the selection of multimedia information, and for the control of other ~ W 0 96t278~3 CA 02214711 1997-09-04 PCT~US96/03137 devices. It is also known that a more conv~llLional remote control could be utilized such as one that controls a VCR or a television and its use would be within the spirit and seope of the present invention. The remote control 900 also ineludes a positioning function. Aeeordingly, a motion deteetor or the like can S be utilized within the remote to allo~v for l,viulil.~ the remote at the television monitor to ll~u ,mil certain iurO~
Another fealule of the al~v~-ide~ ied system arehitP~t lre is that the pi~la~ i;nform~tion ean be linked to the n< twulk to provide for enh~nce~
iutera~ v~ and l,.vg~ quality. For ~qmpl- the l.rogl~ souree ean follow or be ?~llcllrvni~d with ~e eable or bro lcqct feed to provide for enhqnr~l distnbution of p:~a~ inf~nnP1;~.n One s~ ;I;c c~ple of this to take a new program, like CNN bl~ - k ~ 5, whieh co--r: '~ of several short news items. For eaeh news there could be stored lqrge ~i~_s or l~rGol ~ n~pteriq-l rdated to a I,all~ular story. Henee, through m~ll;...E~iq inl~ ivll with for, .~ ,~e, the lc~te control 900 the stored l~.o~al~, mqte~iql can be -~c~ . This would allow the user to review the mqteri~q-l in wLat_~_r detail was desired.
Another ~ " is in an a~ellisil~g feed if a ~ ular item was a~_l Lisc.l, there would be the ability to refer to more ~et-q~ 5 ~ about the product.
Yet another .~ ple of such a system is to have one service linked to ~oll~er. An adv l li~ . -~t could be linked to a means for ordering the particular luel being a~h_.L~d ircl~ ing the p'~c~ent of a phone call by the IMDs to the desi~d telephone n~b~.. In so doing, the linked system allows for additional services to be ~ce~
The illl~.~nl requirements for this linked fealul~ is that there is a kno~lc~c of the contcnls of the system p~O~,I~ re~lui~ ents and there is a knowledge of where the user is in the l,rG2;l~. For example, an IMD could be used for ch-q-nnel ~,rGb,~l idc~t;r;-~ion in which the telephone call is linked to a particular ch-qnnel that has been selecte~1 Another example is link demographics for targeted interactive adve~ hlg.

W 0 96/278~3 CA 02214711 1997-09-04 PCTrUS96/03137 Hence, in an advel lisement for a diaper, for example, there would be the facility to access a~elLi~ents for related items such as baby powder, baby oil or the like through the use of this linked approach.
In one embodiment, a code is utilized by the telephone, either activates as a single button on the telephone keypad or remote control on a plurality of alph~m~meric l~ullo,.s on the telephone keypad or remote control is utilized as the linkage bcl~.~,en the c~ctQmer and the l~all~ular service to be utilized. The code would then allow for user s~lçct-q-ble, remote access to goods and services.
RPfel~ ;, now to Figure 13 what is shown is a flow chart of the o~elal;o of cuch an ~"xl~k multimedia infor~qti~.~ syctem when icc~linS~ cc.. pons is viewed by a customer via step 1302 on the television monitor. Therear~r the mer can select from a .~ . of .li~ e,,l coupons via step 1304.
TJ~ere~ftcr, the MPS generates a cou~o~ order via step 1306. Whether the interactive de~;ccs are in a central locs ~ or in a each room the "--cl~-..er can order by the device interacting with a c-q-t-q-log order desk l ac~c~l in the facility, via step 1308. The cvYpo-~ can be ~.vv;~led dh~lly through the Ar~--p..lel of the facility or on the other hand can be provided to the user in the room. That transaction can be completed step via the remote control 900, a il~te~ t*e device or telephone.
A cc.u~ can then be ~1, te.l at the front desk through a special printer be delivered via steps 1312. Finally, the co--~- could be delivered either to the hotel f~r.iliti~ to the ~ ....e.~ home or to her place of l,~ine~ via step 1314.Finally, there could be ~ of methods of delivery and there use would be within the spirit and scope of the prc~l,t iu~e~llion.
Refellil g now to Figure 13A what is shown is an automated call oeec -~ system utilized to iulpl~ ulent the col.~o~ g system of Figure 13. In this embodiment the system places a call to the telephone number of the cou~on source via step 1306-1, then the MPS 102 connects to the catalog source via step1306-2 and send, an auton~te~ message such as "You have reached the cable nelwolk for ABC hoteL press 1 to conSrm." After the connection is confirmed W O 96/278~3 CA 02214711 1997-09-04 PCTrUS96/03137 the MPS 102 it will then send order information to the coupon source via step 1308-1. The source will then acknowledge the order via step 1308-2. The source could for e~cample confirm demographic information and the like during this step.
This system would have particular utility in conjunction with multimedia yellow pages. Hence, the customer can review through advertising typical vendor information as found in the yellow pages except now this information is reviewedfrom a tele.ision. Sele~l;ol.s can be made using the remote control 900 to obtain certain inforn~ n and. thereby c~ g several related actions to occur. By pls~cement of the telephone call a vendor could issue a ticket or coupon for a product or a sc,,~icc. An i."~.l~l ~ealure, for the printing of ~ ments is the need for an i~ y control system in which the ~ .cl can gain access to infQ ~ that pertains to her transactions.
Rcf~llilg now to ~ C.S 14a and 14b what are shown is an el~11~, .c lo~ control system 1400 and a ~h~ al in. ~ control system 1400'.
R~f<.,;.~g first to Figure 14a the el~L.o~ic co.. l.ol system in.~ s a pel onal n,tel 1402 with an ~ teA dis~)la~ in this case a CRT display 1406. Also c~,u~led to the ~e~ âl c~ t~r is a key~ad 1408 and a l,l~t~r 1404. The pl .Icr in turn is coupled to an IMDV output device 1410.
In such a systcm the keypad 1408 can be utilized by the .,..sl~ er in much the same way as an ~ 1;c teller m-~hine (ATM) in which the cl.~tQmer has a security code t_rough the use of a room Icey to allow the ~ -.el to order c~,upons via the ~ersc,~al CC~ 1402. The c., -puter is linked to the MPS 102 to allow for secure access to the various sources of information. The display 1406 can be utilized to interactively oyclale with the pelso-lal cc-ull3uter to cause the ylhlling out of the ap,o~ ale coupons via the printer 1404. The pri-nter 1404, typical}y a laser yli lte~ or speci~li7e~ c~upon printing m-chine prints the information and provides that printed c.,.lpon information to a secure output device 1410.
Figure 14b has similar elements to Figure 14a, however the physical s,vstem includes a tray for receiving the tr~n~ctional information. Therefore each W O 96/278~3 CA 02214711 1997-09-04 PCTrUS96/03137 customer can have access to an individual tray of information by using their hotel key or the like. Through the inventory control systems shown in Figures 14a and 14b the cl-stomer has secure access to inteld~ e multimedia tr~n~qctions.
It should be understood that the IMD 110 itself could be utilized as a call S proce~-;.. g system. Finally, it should be understood that there could be multiple MPS 102 to provide for very large scale call procc~ through the MPC 109.
The above-described CG~l~v.lhlg system has si~ifir-q-nt utility in the linking of ccju~u..in~ inf nnqtion with other informq1ion. For example, the c.~u~o~ can be linked to di~c~ t cat~,oli~s in the store which in turn can be linked to the iu~ ~lu- ~ in real time. In anol]~ A~u~l~, demographic informqhon or the like can be linked to the f ~ ;lJt of a c.~upo~. In a third ~ Ip~ the is~uallc~ of a can be linked to a &~ c!;~;.e profile of a user. In this eml.odi~c~t, the user makes a choice based upon the a.h_.Li~ nt l,.~L~ted. A co-.~o.. is then gene,~te.l which is either related to the product a~-.l;3ed or is c~ ivc with that product. In so doing, a fully interacthe co l~ g system is provided.
Fi'nal~y, this system could be utilized for in store lin~ . To more ~al l~ular}y ~ nl~e the advantages of this fcalure, refer now to Figure 15 whichis a store KIOSK in which the user can order the coupo.. desired. The KIOSK
1500 includes a video screen 1502 with a keyboard 1504 or the like to input the dcsn~,d info~nq~ - In a first e.. ,b~li~ent, the coupun is code based, that is a cl~t--mer enters the store and orders a I,arli iular co..~ or set of cv.ll.vns based upon a code that he/she enters on the keypad.
In a second c ~bcsdiLu ~t the cvupon is issued based upon an all~el lise"~ent. The ~ ....er would hear and see a particular advertisement prior to the issuance of the coul,ou. In this embodiment, a particular brand is ordered at the KIOSK 1500 and a coul on is printed that allows for a discount on that brand.
In yet another embodiment, the KIOSK 1500 includes a plurality of food recipes. The user orders a particular recipe via the keyboard and there would bea variety of cOu},olls generated based upon that particular recipe.
-3l-~ W O 961278~3 CA 02214711 1997-09-04 PCT~US96/03137 This type of in-store couponing system can also be utilized in a store without the KIOSK 1500 descl il,cd above. For example, the code information for the coupons could be provided directly at the ckecl~out stand. Accord~gly, when the cl~stc.mer purchases the ~l,;o~liate product, the COu~o,l codes or one code S re~.~l.li.lg a plurality of coul,o~.s would also be provided directly to the sales person at the check out stand. For exarnple, one code could ~ esellt four pro~uct~. A shopper may order 10 items, that inrl~les three of the four items te-l with the code, within the POS system of the store, the C~U1JOJ1 values A~ with those three items would then be ~,eLled utili~ng the code, rather than le.~ , a ~p~d~ code for each item. In so doing, the c~ vn ;..fo .-.zl:-.., is provided ~ e~ at the point of sale (POS).
Although the present i~ n has been descnbed in - cc !~rda~ce with the eml~li~ .,t, shown in the figures, one of ordi~ skill in the art reco~ e~5 there could be v~ lions to the ~ - .bo~ ts and those ~,aliali~ns would be within the spirit and scope of the l,r~nt i~.e li~ . A~oldi....... gly, many ~o l;r~ ons may be made by one of ordinary slcills in the art ~ o.. l depa~ g from the spirit and scope of p:~nl in~e~Lon, the scope of which is d- filled solely by the Appe~ e-l claims.
