Definitions

  • This invention relates to a multichoice reception system for signal transmissions, such as a reception system for multichoice television channels.
  • Radio and television broadcast reception systems are well-known.
  • a receiver can be tuned by a user so as to select a particular broadcast programme at any given time.
  • modern radio and television receivers are often provided with so-called “presets", which may take the form of respective keys provided on the receiver itself or on a remote control unit therefor, which keys, upon actuation, tune the receiver to respective broadcast frequencies which are preprogrammed by a user.
  • More sophisticated arrangements of keys may be provided in order to allow the receiver to be tuned to a large number of frequencies without requiring the provision of a corresponding number of keys.
  • ten keys numbered zero to nine, plus an "enter” key allow any number between zero and 99 or even higher to be entered, and it can be arranged that keying in any of these numbers or "channels" results in the receiver being tuned to a respective broadcast frequency which has been preprogrammed by a user to correspond with that number or channel.
  • a single key or pair of keys may be provided, successive and/or prolonged actuations of which step the tuning through a preprogrammed sequence of broadcast frequencies, either in one direction for a single key or in opposite directions in the case of respective keys of a pair of keys.
  • the presets may be voice-actuated, the receiver or remote control unit being capable in such a case of recognising simple spoken commands such as "up”, “down”, “one", "two", “three” etc.
  • a fibre-optic cable for example, is capable of carrying several hundred television programmes simultaneously. Availability of such a large number of programmes for reproduction by a receiver does, however, create selection problems for a user of the receiver; so-called "channel surfing" becomes impracticable, or at least hit-and-miss, and perusal of complete programme listings becomes a major undertaking.
  • UK patent application GB-A-2 263 035 (Thomson Consumer electronics inc) describes a video cassette recorder (VCR) which includes apparatus for controlling a cable TV converter unit: the objective being to make it easier for users to program their VCR.
  • VCR video cassette recorder
  • the application acknowledges the programming simplification system referred to as VCR PLUSTM but suggests that this is rendered less useful for cable TV subscribers as they receive broadcast TV channels over cable TV channels, and hence there is not necessarily any universal correspondence between the channel number assigned to a broadcast TV channel and that allocated to the cable TV channel which carries that broadcast channel.
  • VCR which includes VCR PLUSTM and an autoprogramming capability: "the channel mapping facility may be greatly simplified by using the autoprogramming features to locate and program all active channels, and then by mapping in a channel guide list only those channels which are active, instead of requiring the user to select all 125 possible channel programming positions.”
  • European patent application EP A 0 424 648 (General Instrument Company) describes a television distribution system in which alternative "channels" of commercials are provided for insertion into the commercial breaks of the programming, the particular advertisements selected for transmission being determined (typically by the set top box in a cable TV system) on the basis of the personal demographics of the viewer(s).
  • the viewer may be called upon to specify demographic details (sex, age, etc) or the viewer's apparatus may be programmed with the relevant information on installation. At least where the user enters personal specifics (age or age group and sex) it is possible for the advertising to be very closely targeted at the likely interests of the viewer.
  • the signals need to be distinguishable, so that the selection means can differentiate between them. They do not need though to be of a particular type.
  • the signals might be digital in which case they might for instance be distinguishable by containing different respective identifying sequences.
  • the signals might be analogue in which case they might be distinguishable for instance by having different respective carrier frequencies.
  • the signals might be transmitted from the same source, or from different respective sources.
  • the receiver could be a television receiver, provided with keys which allow the user to enter specific channel numbers.
  • the correspondence between these channel numbers and the transmissions which are selected when these numbers are entered can then be adjusted, according to an embodiment of the present invention, by the mapping adjustment means.
  • the adjustment could be performed so as to conform with expressed or estimated preferences of the user for programmes being transmitted.
  • the user may, for example, have pre-notified an operator of a system according to an embodiment of the present invention that normally his first preference is for programmes of a first category, for example films, his second preference is for programmes of a second category, for example news programmes, and so on.
  • the mapping adjustment means may be arranged to adjust the mapping automatically in such a way that, at any given time while the receiver is operating, the individual programmes of the first category can be selected by entering the numbers 1 to N, where N is the number of programmes of the first category currently being transmitted, the individual programmes of the second category can be selected by entering the numbers N + 1 to N + M, where M is the number of programmes of the second category currently being transmitted, and so on.
  • the mapping adjustment means may be arranged to automatically adjust the mapping in such a way that the individual programmes of the first category are selected first in the sequence, then the individual programmes of the second category, and so on.
  • the mapping adjustment means are arranged, in operation, to estimate automatically the preferences of a user of the receiver in respect of the currently available programmes and adjust the mapping in accordance with the results of the estimation. If this is the case it can be arranged, for example, that when the user selects channel "1" the receiver reproduces the programme which it is estimated will be his first choice of those currently being transmitted, when he selects channel "2" the receiver will reproduce his estimated second choice, and so on.
  • a multichoice programme transmission and reception system comprises M sources 1 1 , 1 2 , ... 1 m of respective concurrent programmes where M may be, for example, several hundred.
  • the sources 1 may comprise, for example, video or audio tape or disc playback machines, receivers for respective broadcast television or radio programmes, etc.
  • First outputs 2 of the sources 1, which outputs carry the respective programmes, are coupled to respective inputs of a multiplexer 3, for example of the frequency-division or time-division type.
  • the output 4 of multiplexer 3 is connected to a trunk cable 5, for example a fibre-optic cable. Trunk cable 5 feeds in turn the input 6 of a splitter 7 outputs 8 of which feed local drop cables 9 which again may be of the fibre-optic type.
  • the cables 9 couple the splitter 7 to first inputs 10 of respective subscriber's receivers 11 which are each capable of selecting a programme from one of the sources 1 and reproducing that programme.
  • the part of the system of Figure 1 described so far is conventional.
  • the sources 1 have respective data outputs 12 and the receivers 11 have respective data input/outputs 13.
  • the data outputs 12 are coupled to respective inputs 14 1 , 14 2 , ... 14 m of a data processor 1 5 and the data input/outputs 13 are coupled to an output/input 16 of processor 15 via a multiplexer/demultiplexer 17.
  • the multiplexer/demultiplexer 17 and the couplings between it and the receivers 11 and the processor 15 may for example be constituted by part of a public switched communications network.
  • data communications between the output/input 16 of processor 15 and the input/outputs 13 of receivers 11 may for example be achieved via the trunk cable 5 and the respective local drop cables 9 if they, the splitter 7 and the multiplexer 3 are made bi-directional, and an input/output is provided on multiplexer 3 coupled to the output/input 16 of processor 15.
  • the multiplexer/demultiplexer 17 together with the couplings between it and the receivers 11 and the processor 15 may, of course, be omitted.
  • FIG 2 is a block diagram of each receiver 11 of Figure 1.
  • the receiver 11 comprises in known manner a controllable selector 18 for selecting any one of the programmes supplied to the input 10 from the sources 1 of Figure 1 and passing it on to the input 19 of programme reproduction means 20.
  • Reproduction means 20 may, for example, comprise an audio amplifier and loudspeakers if the programmes supplied to input 10 are audio programmes, or a video amplifier, a display device and circuitry for controlling the display device if the programmes supplied to input 10 are video programmes.
  • a control input 21 of selector 18 is fed with control signals from an output 22 of a suitably programmed micro-processor 23, the control signals determining which programme is selected by selector 18 and passed on to reproduction means 20.
  • a key-pad 24 which enables a user to enter channel numbers has its output coupled to an input 25 of microprocessor 23. Each time a channel number is entered by a user into key-pad 24 while the receiver is operating, microprocessor 23 responds by generating a digital code on its output 22, which code causes the selector 18 to select a specific one of the programmes fed to input 10.
  • a memory 26 is connected to an input/output 27 of microprocessor 23 and the receiver on/off switch 28 has an output 29 connected to an input 30 of microprocessor 23.
  • microprocessor 23 responds by accessing a location in memory portion 26B which is assigned to that channel number and reads out the contents of that location. These contents constitute the address of a location in memory portion 26A and microprocessor 23 uses these contents to address that location and read out its contents onto its output 22.
  • which programmes are selected by selector 18 in response to the entering of the various channel numbers into key-pad 24, i.e. the mapping of the channel numbers to the programmes, is, unless this feature is disabled, determined by the look-up table in memory portion 268.
  • These contents can be and are changed in operation in response to data supplied to receiver input 13 by the processor 15 of Figure 1, these changes potentially occurring upon switch-on of the receiver 11 and subsequently each time a programme supplied to input 10 ends and another begins, until the receiver is finally switched off again.
  • the microprocessor is programmed to dispatch first and second specific signals on input/output 13 to the processor 15 of Figure 1 each time the receiver 11 is switched on and is subsequently switched off respectively, signals being supplied at these times to input 30 from on/off switch 28. These specific signals each identify the receiver 11 from which the signal has come.
  • Processor 15 uses these signals to maintain in storage a list of all the receivers 11 which are currently operational. Processor 15 is furthermore supplied on its inputs 14 with information from the sources 1. This information is supplied from any source 1 each time that source commences transmission of its next programme, and identifies that programme. Processor 15 responds to reception of each such item of information by storing it in memory at a location assigned to the relevant source 1, overwriting any such information from that source which has been previously stored. Thus at any given time processor 15 also has in storage a complete record of the programmes being transmitted by the respective sources 1.
  • Processor 1 5 responds to reception of an aforementioned first specific signal from a receiver 11 by generating an order of preference which it is estimated the user of that receiver will have for all the programmes currently being transmitted by the sources 1. (A manner in which this can be done will be described below). Having done this processor 15 sends a message to the input 13 of the relevant receiver 11 identifying this order of preference in terms of the particular sources 1 which are transmitting the relevant programmes.
  • the microprocessor 23 in the relevant receiver 11 responds to such a message by reprogramming the look-up table in memory portion 26B in such manner that, for example, a "1" entered into keypad 24 results in selector 18 selecting the transmission from that source 1 which is transmitting the programme for which it has been estimated the user will have highest preference, a "2" entered into keypad 24 results in selector 18 selecting the transmission from that source 1 which is transmitting the programme for which it has been estimated the user will have second-highest preference, and so on.
  • the user of the relevant receiver 11 can access in turn the current programmes which it has been estimated he will prefer, in decreasing order of estimated preference, simply by entering the channel numbers one, two, three .... in succession into the keypad 24.
  • the processor 15 of Figure 1 receives a signal from each source 1 each time that source commences transmission of a new programme, the signal identifying that programme. Each time this occurs, in addition to updating its record of which programmes are being transmitted by which sources 1, processor 1 5 recalculates the estimated orders of preference for the users of all the receivers 11 which are currently operational and transmits the results to the respective receivers via their inputs 13.
  • the microprocessors 23 in the relevant receivers respond to reception of these new orders of preference in the same way as they did to the order of preference received upon switch-on, i.e. by reprogramming the look-up table in the corresponding memory portion 26B to accord with the new order of preference. This periodic updating of the look-up table in each operational receiver continues until the relevant receiver is subsequently switched off, i.e. sends an aforesaid second specific signal to the processor 15.
  • the processor 15 calculates, or at least dispatches, a complete order of preference each time; it may be arranged to identify just the top few estimated preferences, out of a total number of programmes which is much more than this, and send these to each operating receiver 11. Furthermore it is not essential that each and every receiver 11 is supplied with, and utilises, the estimated order of preference information while it is in operation; it may be, for example, that this information is supplied only to receivers the users of which are subscribers to such a service. Furthermore it is not essential that the processor 15 takes into account all the programmes transmitted by the sources 1 when it estimates the orders of preference in respect of each operating receiver 11; it may take into account merely a selected category or categories of programmes, e.g. films, serials, news programmes, etc, etc.
  • a method by which the processor 15 may estimate the preferences of the respective users for the currently-transmitted programmes will now be described.
  • This method is particularly but not exclusively applicable to the estimation of orders of preference within a particular category of programme such as film, and relies on the processor 15 having information about the ratings which have been given to respective ones of these programmes, and to other programmes, by people in the past, and about the ratings which have been given in the past to at least some of the other programmes by the users of the receivers 11.
  • a database of this information is maintained in memory in the processor 15 or elsewhere in such a way that the ratings given to various programmes by the same person can be identified as such.
  • These ratings may be obtained, and the database increased, by for example requesting each user of the system to rate each programme he has just watched on a scale of, say, 1 to 10 and send this rating together with the identities of both the programme and himself to the processor 15 via the data output 13 of his receiver 11. If, for example, the preference estimation is limited to films then, on the assumption that most films are transmitted more than once, the database will eventually contain ratings on most of those currently being transmitted. As far as films which have not been previously rated are concerned these may merely be automatically included in, or excluded from, a short list of estimated preferences for a given user in accordance with instructions he has previously given.
  • Figure 3 is a flow diagram of the various operations carried out by processor 15 of Figure 1 when such a method is employed, in response to the switching on of any receiver 11 and, in respect of each and every operating receiver 11, in response to the start of transmission of a new programme by any of the sources 1.
  • the various blocks etc have the following significances. 31 - Start 32 - Set the identification number s of the source 1 whose currently transmitted programme is to be rated for the user i of the receiver 11 under consideration to unity . 33 - Has the user i already rated the programme k s currently being transmitted by sources? 34 - For each other programme, calculate the correlation between the ratings (if any) other people have given this programme and the ratings (if any) the same people have given the programme k s .
  • 35 Determine the N programmes the ratings of which exhibit the highest correlation, as calculated in 34, with the ratings of programme k s .
  • 36 For each of the other people determine the equation of the straight line which best fits the set of points which would be obtained by plotting the rating given by user i to each of the N programmes against the rating (if any) given to the same programme by that other person.
  • 37 For each of the other people calculate, using the corresponding equation determined in 36, the equivalent rating for user i to the rating (if any) given to the programme k s by that other person.
  • 38 For each of the other people calculate the correlation between the rating (if any) he has given to each of the N programmes and the rating which user i has given to the same programme.
  • Test 42 and steps 32 and 43 merely ensure that an estimated rating for user i is calculated for each of the programmes currently being transmitted by the sources 1, with the exception of any programmes he has previously rated. (It is assumed that user i will not wish to experience again any programme he has previously rated. Of course the opposite assumption could alternatively be made, in which case the path from the "yes" (Y) output of test 33 to test 42 should include the further step of storing user i's previous rating as the estimated rating for the programme currently being transmitted by the relevant source s).
  • Steps 34 to 36 serve to determine "best-fit" linear equations for converting ratings given to programmes by other people into equivalent ratings by user i.
  • Steps 34 and 35 serve to ensure that the data used in the actual determination in step 36, i.e. ratings previously given to specific programmes by both user i and other people, is that which is likely to give the most accurate result when the equation is used to convert the ratings previously given by the other people to the programme k s into an equivalent rating by user i. More specifically the data is chosen to be that which relates to the N programmes whose ratings by the other people are most closely correlated with the ratings they have given to the programme k s . In practice this normally means that N programmes are selected which are of the same genre as programme k s or are similar in other ways, e.g. appeal to the same age group.
  • step 36 Having determined the "best-fit" equations in step 36 for each of the other people these equations are then used in step 37 to convert the individual ratings of the programme k s by the corresponding other people into equivalent ratings by user i.
  • a further "best-fit" linear equation is then determined in steps 38 and 39, this time for converting the equivalent ratings obtained in step 37 into an overall estimated rating for the user i.
  • This conversion is done in such a way as to take into account, for each person whose rating of the programme k s has given rise to an equivalent rating in step 37, the correlation between the ratings he has given the N other programmes and the ratings user i has given the same programmes. Accordingly the relevant correlations are calculated in step 38 and the further best-fit equation is determined in step 39 as being that of the straight line which best fits the set of points which would be obtained by plotting the equivalent ratings against the correlations calculated for the people from whose ratings the equivalent ratings have been derived. The estimated rating is then calculated from the further best-fit equation in step 40 as being the equivalent rating corresponding to a correlation of +1.
  • the sources 1 are ordered in step 44 in terms of the corresponding estimated ratings and this order is transmitted to the receiver 11 of the user i in step 45.
  • the estimated ratings for the user of another receiver 11 can be calculated and the sources 1 ordered in accordance therewith, and so on for the user of each receiver 11 in succession.
  • the estimated ratings for the users of several receivers can be calculated, and the sources correspondingly ordered, in parallel with each other.
  • the processors 23 in the various receivers 11 are programmed to respond to reception by the relevant receiver of an order of sources 1 from the processor 15 by reprogramming the look-up table in the corresponding memory portion 26B.
  • This look-up table contains a memory location corresponding to each channel number keyed into key-pad 24, whereas memory portion 26A contains a memory location corresponding to each source 1.
  • the microprocessor 23 Upon reception by the relevant receiver of an order of sources 1 the microprocessor 23 responds by writing the addresses of the various locations in memory portion 26A into respective locations in the memory portion 26B so as to produce a mapping between the various channel numbers and the various sources which corresponds to the received order of sources.
  • each receiver 11 may be provided in each receiver 11 for disabling/enabling the reprogramming of the look-up table. This may be arranged to occur, for example, in response to the entering of specific codes into the key-pad 24, and disabling may be arranged to result in the creation of a predetermined fixed mapping between the channel numbers and the sources, which mapping is maintained until the reprogramming is subsequently enabled once again.
  • each microprocessor 23 may be programmed to cause the programme for which it is estimated the user of the relevant receiver currently has the highest preference to be automatically selected upon switch-on of the receiver.
