Abstract

Disclosed are a method, apparatus and computer program for dynamically changing a display. A screen markup format is encoded in teletext information and transmitted from a signal source to a receiver, where it is decoded from teletext information into a markup language format and transmitted to a portable display device.

Description

2352600 METHOD, APPARATUS AND COMPUTER PROGRAM FOR DYNAMICALLY CHANGING A
DISPLAY The present invention relates to the field of interactions between computing devices, such as handheld computers and other devices, such as interactive television set-top boxes. It relates more particularly to means for communicating between devices to dynamically change the information displayed on a screen.
Future computing environments are likely to have the characteristics of what has been termed "pervasive computing". That is to say that users will have available to them a variety of devices capable of interacti - ng to permit computing tasks to be carried out with reduced limitations as to place, as compared with the current personal computer and telephone line technologies. Some of these devices will have extensive computing capabilities, while others will be merely controllable to carry out specialised functions at the request of some communicating device in the npervasive computing" environment.
one particular development in technology is likely to prove significant: the use of hand-held computers or personal digital assistants (PDAs) in conjunction with other devices, such as personal computers or interactive televisions.
some work in this area has already been carried out; for example, the use of programmable personal digital assistants (PDAs) as universal remote control devices using software technologies such as IBM's Mobile Document Application Language (see http://www.infoworld.com/cgi bin/displayStory.pl?981224.ehmodal.htm for details) PCT Application W099/14953, to Lee et al., discloses an access system and method to provide interactive access to an information source such as the Internet, through a networked distribution system, such as a television distribution system. The system operates by permitting users to transmit requests from a keyboard connected by wire or wirelessly to a set-top converter (sometimes also known as a set-top box, or STB) through an upstream channel of a television distribution system to a head-end apparatus, which in turn requests Internet information via a conventional browser program. The Internet information is then transmitted through a downstream channel of the television distribution system by inserting it into the vertical blanking interval (or flyback interval) of the analogue television signal. Thus, a conventional broadcast network is extended to permit a request-response communications model to be provided.
Accordingly, in a first aspect, the invention provides a method for dynamically changing the display on a screen of a portable display 2 device, the method comprising the steps of at a receiving system:
receiving a signal from a signal source; identifying encoded teletext information within said signal; decoding from an encoded teletext format to a markup language format; and transmitting said markup language format to a portable display device for display.
Preferably, said markup language format permits the identification of actions able to be performed by said portable display device. Further preferred is that said actions comprise transmissions of information by said portable display device. The method preferably further comprises a step of accumulating said markup language format from a plurality of frames of said encoded teletext information before said step of transmitting.
In a second aspect, the invention provides a method for dynamically changing the display on a screen of a portable display device, the method comprising the steps of at a sending system: encoding content information and one or more tags of a markup language format into teletext information; and transmitting said encoded teletext information on a television signal channel.
The method preferably further comprises a step of spreading said markup language format across a plurality of frames of said teletext information before said step of transmitting.
The invention, in a third aspect, provides a computer program comprising program steps which cause a computer to perform the steps of any of the methods as described above.
In a fourth aspect, the invention provides apparatus comprising: a signal receiver arranged to receive television signals containing teletext information; a teletext -to -markup language format converter; and a transmitter arranged to transmit a markup language format to a portable display device.
in a fifth aspect, the present invention provides apparatus comprising: a markup language format - to- teletext information converter; and a transmitter arranged to transmit teletext information on a television signal channel.
The present invention is unlike the system of Lee et al., which is well suited to solve the problem of supplying users with Internet or other complex information obtained at an adapted distribution headend.
The system of Lee et al. is overly complex for the provision of relatively simple information, such as is required to display sets of touch-screen buttons on a PDA, and to modify them dynamically. It has a 3 further problem in that considerable adaptation of the standard equipment of cable or television headend servers (the transmission sources) is likely to be required to make them practicable for transmission of data packets representing Internet or other computer information across the same transmission channels as normal television signal information. This expensive procedure could not be justified to provide the rather simple functions of an adaptable remote control implemented on a PDA. It is desirable to avoid the expense of such conversions or replacements of existing equipment, which by the nature of the demands placed on it is likely to be expensive, specialised, "high-end" equipment which is not manufactured in sufficient numbers to achieve great economies of scale.
By contrast, the per-unit expense of providing extra facilities in the receiving equipment is likely to be small.
A preferred embodiment of the invention will now be described in detail by way of example with reference to the following drawings:
Figure 1 shows an interactive television system suitable for browsing the Internet as disclosed in Lee et al.
Figure 2 shows a system of the present preferred embodiment.
Figure 3 represents a broadcast cycle for a broadcast channel.
Figure 4 shows an example of a screen display according to the preferred embodiment.
In Figure 1, in a system as disclosed in Lee et al., a cable headend (101) is connected by bi-directional cable (102) to a set-top converter (103), hereinafter referred to by its conventional abbreviation as an STB. The STB is connected to a television set (104). A keyboard (105) communicates by wire or wirelessly with the STB. If the communication is wireless, the STB and the portable device will each require to have an IrDA port capable of transmitting and receiving signals.
In a typical interaction, a user makes a selection by typing on the keyboard (105), which signals to the STB (103). The STB interprets the signal and, for example, selects a channel on the television set (104).
Also disclosed in the prior art is the possibility of the STB interpreting the signal and in turn transmitting a signal to the cable headend (101) using one of a number of upstream channels. The cable headend in turn transmits, on a downstream channel, a signal to the STB.
This signal may be, for example, a page of World wide Web (WWW) data.
The STB may then transmit the WWW data to the television set for display.
4 In Lee et al., the signals transmitted between the cable headend (101) and the STB (103) use part of the cable television bandwidth to "piggyback" the signals, inserting them in the blanking interval (or flyback interval) of the television signal. During the blanking interval, frames of non-picture information are transmitted on a downstream channel of bidirectional cable (102). The upstream transmissions of signals from the STB to the cable headend using the upstream channels are synchronized using the frame synchronization signals.
In Figure 2, showing a system of the present preferred embodiment, a teletext signal is transmitted from the signal source (201) in the conventional manner for such signals. The signal is transmitted using unidirectional means (102), either wired or wireless. The teletext signal is received by the STB (203), which identifies the teletext page as a display update page. The STB (203) transforms the teletext data into a markup language format suitable for updating the display on the PDA (205), and transmits it to the PDA using IRDA. If the markup language is XML, for example, the markup may cause buttons to be placed on the touch-screen of the PDA and specify programmatic actions to be taken when such buttons are activated, including the remote control of the televisions set or other devices. The further processing of any such markup is beyond the scope of the present embodiment; however, it will be clear to one skilled in the art that various uses may be found for markup language formatted pages transmitted from the STB to a touch-screen display of a PDA.
In more detail, Figure 3 shows a schematic representation of a single cycle of transmission of a television signal picture frame (301) and its vertical blanking interval (302). In the vertical blanking interval is inserted the teletext formatted content.
Use of blanking interval (302) to transmit non-picture information is known from teletext transmissions in the context of transmitting text and pixel graphics to television sets adapted with a teletext decoder.
Teletext is a one-way broadcast television service for transmitting information using the standard videotex protocols. It is thus well suited to the broadcasting of simple encoded information to dynamically alter the contents of a touchscreen display on a PDA without the complexity and expense of interactive television. Advantageously to many broadcasting organizations, the skills, equipment and software to enable them to produce encoded teletext signals are already in place. The additional expense and effort of using these means to transmit screen display information is relatively low, and the steps of the method are suitable for automation preferably using software to avoid the expense of producing dedicated hardware.
The preferred embodiment advantageously exploits the use of one r more dedicated teletext pages, which are updated at a similar refresh rate to that of the subtitle page 888 of the United Kingdom Teletext system.
The preferred embodiment further advantageously exploits the teletext standard protocol by, at the STB, decoding specified codes in identified teletext signals from the encoded teletext format into a markup language format. The material in markup language format is then transmitted to the portable device in the form of an IRDA transmission.
markup language formats are well known to those familiar with desktop publishing, text processing, hypertext and the Internet. The most extensive markup language is the Standard Generalized markup Language (SGML) f from which have come a number of derivative languages. one such is the Hypertext Markup Language (HTML); another is the Extensible Markup Language (XML).
In the preferred embodiment, the STB is either a device containing an application-specific subsystem, such as an Application Specific Integrated Circuit (ASIC), or it may be a device having a capability to be programmed in software to perform the steps of identifying and decoding the encoded teletext and encoding it in a markup language format for transmission to the portable device. The IBM Set Top Box Reference Design Kit (see http://dreamchips.btv.ibm.com/settopbox/designkit.html for details), provides an integrated hardware and software development environment suitable for producing a set-top box according to the preferred embodiment.
The preferred embodiment thus provides means to transmit and dynamically modify the touch screen display of the portable device. So, for example, while a user is watching one of the channels provided by a television service provider, the standard channel change and volume buttons may appear as touch screen areas, but the service provider may use the remaining screen area to highlight the start of a particular pay per-view event on another channel, or to advertise goods and services in parallel with a product placement in a f ilm.
Figure 4 shows a possible screen arrangement having conventional channel and volume controls on the touch screen, but additionally having a touch-sensitive area showing the count-down to the start of a pay-per view program. The seconds-to-go display is simply refreshed from time to time, and the underlying programmed actions include selecting the channel for the pay per view program and possibly updating a charging meter.
on-line shopping buttons may also be displayed relating to items that have been advertised during the most recent commercial break in the 6 program. For example, if a new model of car was advertised, the service provider may offer the car manufacturer the opportunity to buy online shopping space for a period following that advertisement. The user's PDA may thus be used as a remote control, but also as a means of causing the user to see a button marked "Send me details" on the touch screen.
Pressing the button would transmit an online request for details to the Internet server using known electronic commerce technology, which may comprise communication either by means of a conventional separate telephone line or by using the bidirectional cable communications as disclosed in Lee et al., mentioned above.
