Description

G:\SECDATA\MJB\GOINTER\77703.WPD
AN APPARATUS AND A METHOD FOR REPURPOSING
WEBSITE INTERACTIVE CONTENT
The present invention relates to a method and an apparatus for repurposing website interactive content.
Many companies have spent large amounts of time and money creating a significant web-presence by developing web-based interactive content. The problem 10 with internet interactive content is that its data structure is not suited for transmission as an interactive TV application. However, the "style" and images/text/behaviours that the website interactive content contains may be usable in interactive digital television. The present invention is based on a recognition that the presentation of this content could be modified to suit a display as part of an interactive TV application.
15 According to the present invention, there is provided a method of repurposing website interactive content including: parsing a website file and separating the various components; locating elements of a predetermined interactive TV application to accept the respective components; 20 converting the components from the web format to the interactive TV format; and porting the converted components to the predetermined interactive TV application. According to the present invention, there is also provided a website interactive 25 content repurposing apparatus including: a controller responsive to a user input and for driving a display, the controller being configured with a repurposing tool so as to: (i) parse a website file and separate the various components;
-2 (ii) locate elements of a predetermined interactive TV application to accept the respective components; (iii) convert the components from the web format to the interactive TV format; and 5 (iv) port the converted components to the predetermined interactive TV application., In this way, the web content can be imported into a digital TV interactive content development tool to produce a unified web/digital TV content style based on common resources. 10 By breaking up a website file into its component parts and identifying those components which can be converted for use by an interactive application, an interactive application can be created with a corresponding look and feel to the website.
Porting refers to understanding the functionality provided by a piece of code and implementing the same functionality on a different environment or platform. Depending 15 on the platform, the application and the particular functionality provided, the porting may be done be either taking an existing application skeleton and adapting it by setting parameters and/or linking extra software objects (module, see below); translating the HTML tags and/or javascript into the application language using known parsing and compiling methods; and linking together pieces of pre-compiled code (modules), each 20 one of which provides some little functionality, and which once combined all together provide the desired overall functionality.
Preferably, then, the controller is configured to provide the predetermined interactive TV application with the same kind of functionality, information, look and feel as the website.
25 Thus, it is not essential that the interactive TV application shares all the same detailed software functions.
Preferably, the controller is configured to convert the html code, scripts, text
-3 data, numbers and pictures of the website into a form suitable for the predetermined interactive TV application.
This will be sufficient to give the same general look and feel, since the html code of the website describes the look and feel of the website. In particular, the controller 5 may be configured to convert the tags of the html code.
Preferably, the interactive TV application is generated by translating objects described by html tags of the website into corresponding objects supported by the predetermined interactive TV application.
In this regard, a set of interactive TV platform objects may be provided 10 corresponding to html tags.
In this way, the html tags which identify the form of the website may be interpreted and converted to the platform objects and, in conjunction with the text, numbers, pictures, etc lifted from the website, used to create the required interactive application. 15 Preferably, the controller is configured to adapt parameters of the website according to the general requirements for use with TV.
In particular, the controller may be configured to adapt the fonts, dimensions, colours and navigation functions used for the website to fonts, dimensions, colours and navigation functions appropriate for use with the predetermined interactive TV 20 application.
Thus, small or intricate fonts inappropriate for TV may be converted to larger more simple fonts. Similarly images of inappropriate colour or size may be recoloured and scaled and aspect ratios may be converted. Finally, navigation functions intended for use with a mouse or similar may be adapted for use with a TV remote control.
25 Components may be introduced in the interactive TV application to cause scrolling of displayed text where there is too much text in the original website to be displayed on a TV screen using fonts more appropriate for TV.
Thus, where the font size is increased for display on a TV, it may not be possible to fit all of the original text on the TV and hence it may be scrolled.
A report list may be generated indicating all software objects and data found in the website together with whether or not and how the object will be translated for the 5 interactive TV application.
Furthermore, a warning and log may be generated where particular aspects of conversion are not possible.
This ensures that the user of the repurposing tool can allow it to run automatically, knowing that he or she will be informed of the nature of the conversion 10 and warned of any problems.
When the predetermined interactive TV application is a compiled language, the system preferably compiles the converted components.
Of course, some interactive TV applications will not require this.
Preferably, the display displays a web page of the website and the content areas 15 of the web page are highlighted so as to allow the user to select parts for conversion.
In this way, a user is able to be selective regarding the portions of the website to be converted.
The repurposing tool may be implemented in software as a computer program and provided on a recording medium. Thus, viewed from another aspect the invention 20 provides a computer readable storage medium having recorded thereon code components that, when loaded on a computer and executed, will cause that computer to operate in accordance with the method described above.
The invention will be more clearly understood from the following description,
given by way of example only, with reference to the accompanying drawings, in which: 25 Figure 1 illustrates schematically a repurposing tool according to the present invention; and Figure 2 illustrates a flow chart for the process of the repurposing tool.
-5 A controller 2 is configured to conduct the repurposing process. As illustrated, it is connected to a display 4 and a user input 6.
It is known to provide various websites on the internet. Having addressed a particular web page, a PC 8 may download the information making up that web page and 5 display it on its display 10.
As illustrated, a web page might typically include some text 12 and/or an image 14. Other graphics, audio or video files may also be reproduced by the PC 8.
The present invention is based on a realization that the basic content of the web pages, for instance text, graphics etc., may equally appear in an interactive TV 10 application. It is then required to provide an interactive application for a particular platform which displays that same content and provides equivalent interactive Functionality. The repurposing tool described below creates an interactive TV application which provides the same kind of functionality, the same information and the same look 15 and feel as an original website, even if not providing exactly the same software functions. The repurposing process may achieve this in an automated way.
Websites are usually composed of html code, scripts, text data, numbers and pictures. The html code is static in form if.html files or dynamic in form if generated on the fly by the server. This code contains tags describing how different objects 20 composing a particular page have to be laid out on the browser's window, together with references to other pages. The scripts, which, when called by a browser, generate html code on the fly, are based on the parameters passed to them with the call.
It is now proposed that the repurposing tool of the controller re-uses that information as described below.
25 Html describes the look and behaviour of every page. A look and behaviour as similar as possible is recreated in the interactive TV application by translating the objects described by the HTML tags (table, forms, pictures, lists, etc) into corresponding
-6 objects supported by the particular ITV target platform. A set of ITV platform objects are provided which map HTML tags and the repurposing tool applies artificial intelligence algorithms to map ones into the others and reproduce the same behaviour.
It is also proposed that the repurposing tool changes opportune parameters so as 5 to adapt the original web page for the TV screen. For instance, it may change font sizes, image formats, colour palettes, etc., Of course, there may be points in the HTML code which are not translatable by known algorithms and which may require manual intervention. Similarly, other points may describe functions which are simply impossible to implement in the target ITV 10 platform. The repurposing tool preferably generates warnings and logs in such cases.
Preferably, the repurposing tool analyses and re-uses scripts as much as possible.
Depending on the way scripts are created and on the particular situation two scenarios are possible. In a first scenario, the script code is analysed and a new script is created; the new script will provide information tailored for ITV. A second scenario would keep 15 the existing script and just create the necessary server utility which will take the output of the web server script and adapt it to the ITV.
Text data, numbers and pictures are reformatted by the repurposing tool when they are to be associated with an ITV application. Text items are checked and if necessary modified or truncated to make sure they fit on the screen when displayed with 20 TV-friendly fonts. Numbers generally do not require a great deal of re-formatting, except when they appear in a table: if on TV, dimensions will have to be checked.
Pictures have different requirements when displayed on a TV platform and it is proposed that the repurposing tool coverts them to accepted formats, checks they have acceptable dimensions and uses colours which are neither unsuitable nor forbidden on TV.
25 Considering now the preferred embodiment of Figure 1, the repurposing tool of the controller 2 first parses the code making up the original website 16. In particular, as illustrated, it identifies all of the HTML/Javascript code 18, the data 20 and the pictures
(of various formats) 22. Examples of date could be text and numbers such as descriptions of items, prices, timetables, dimensions, co-ordinates, etc.
As described above, HTML/javascript languages have tags and functions which distinguish data from the rest of the code (e.g. in the <TD> tag in html). Furthermore, 5 this can be enhanced by artificial intelligence algorithms to distinguish different types of data. Moreover, the system can be linked to the server databases directly, having data served in a raw form.
The repurposing tool parses website content to extract resources, such as images, text and graphics, and behaviours, such as button/link operation, list box scrolling etc., 10 which can be repurposed to digital TV interactive content. Furthermore, it generates a report listing utilisable resources. This is a report with a list of all software objects and data found in the website. For each of them, the report indicates whether or not, and how, the object has been translated in the ITV application.
The repurposing tool of the controller 2 is arranged to repurpose web information 15 to a selection of predetermined platforms. Hence, it includes conversion algorithms for those predetermined platforms and can be supplemented with additional conversion algorithms or new or additional platforms.
Figure 1 illustrates an example of the repurposing tool being used to repurpose the website interactive content for an interactive TV platform 40, such as OpenTV, and 20 an interactive TV platform 60, such as MHEG.
Thus, as illustrated, the HTML/Javascript code 18 is converted to code modules 42 and to MHEG scenes 62.
Similarly, the data 20 is converted to data modules 44 and text files 64 and the pictures 22 are converted to JPEG pictures 46 and PNG pictures 66.
25 In the first interactive TV platform 40, for open TV, the various components are compiled so as to form the required interactive application 48. In particular, in OpenTV (and other ITV languages) some data has to be put in the form of computer language
-8 which then needs to be compiled in order to be used by the TV receiver.
On the other hand, in the second interactive TV platform 60, no compilation is required. In this regard, it will be appreciated that there are two kinds of computer languages: interpreted and compiled. For interpreted languages, the code is taken by the 5 machine as it is and interpreted line by line at run time. For compiled languages, the code has to be compiled and transformed in a binary form in order to be understood by the machine. For example, OpenTV is an ITV compiled language, whereas MHEG is a ITV interpreted language.
Thus, as illustrated, the resulting interactive applications are transmitted over 10 respective first and second broadcast networks 50 and 70 to appear as interactive content on the TVs 52 and 72 of end users.
Figure 2 illustrates the process conducted by the repurposing tool.
In step 100, the repurposing tool is supplied with a website file for repurposing, together with its destination interactive application. Thus, the tool is supplied with 15 information about the website and the application, i.e. where is the website, which pages are to be converted and, for the ITV application which it the target platform, the desired bandwidth, the programme ID number, etc. In step 102, the content areas of each web page to be repurposed are highlighted.
The user may decide to re-purpose only part of the website content. Hence, a possibility 20 is given to select the content to re-purpose. By selecting an object, the repurposing tool can associate the selection with the line in the html/javascript which pertain to it.
In step 104, the repurposing tool locates elements of the interactive TV application to accept the web content. As described above, web page are built out of predetermined building blocks (html tags and other objects) and a collection of 25 corresponding ITV objects are provided for use as part of the repurposing tool.
In step 106, the repurposing operation is started.
In step 108, the repurposing tool converts text from formats which were suitable
-9 - for display on a web page to formats which are suitable for display as part of an interactive TV application. For instance, in general, users will sit further away from a television and, hence, the font sizes of certain text may be increased when converting to the interactive TV application. For large portions of text, opportune scrolling functions 5 will be provided. The aspect ratio of pictures may also be converted, since a PC monitor has square pixels, whereas TV screens have 4:3 rectangular pixels.
As well as the font and dimensions conversions, colours and navigation may also be converted. In particular, colours are rendered differently on TV screen and generally, people do not watch TV holding a PC mouse in their hands, but a TV remote control.
10 They need to be able to navigate (select different objects and scrolling) the application with their remote.
In step 110, the repurposing tool converts any graphics from a web-format, such as JPEG, to a TV format, for instance a bit map for open TV. Pictures formats, text dimensions and other characteristics vary from platform to platforms. However various 15 conversion schemes can be established.
In step 112, the converted website content is then ported to the specified interactive TV application.
In step 1 14, the repurposing tool determines whether or not the interactive application needs to be recompiled for the changes to take effect.
20 Hence, if recompilation is required, in step 116, this process is conducted and, in step 1 18, the updated interactive application is ready for broadcast. Hence, the created application will be a mixture of compiled/interpreted code (as explained above) created by the tool, software objects already available (re-used from a library or collection present in the tool) and resources (text and graphics).
25 By way of example, where a company have a catalogue as a website, the repurposing tool is able to take the HTML/Javascript code, the images and the CGI/ASP/Perl scripts used by the website and create an interactive TV application in a
-10 chosen target platform, such as open TV.
The website code can then be translated into OpenTV C-code, i.e. of the C language, taking into account TV constraints, such as fonts, dimensions, colours and navigation. 5 Images can be converted to a format supported by an open TV set top box, such as JPEG and MPEG-I frame. The scripts of the website can be reused through the open TV HTTP layers and the use of the modem in the set top box. In other words, where the aforementioned CGI/ASP/PERL scripts communicate with remote clients using the HTTP protocol, this can be used by HTTP ITV application as well, since it is available 10 in OpenTV receivers.
In this way, the content available on the website will also be available on the set top box for TV use. Thus, if the interactive TV application and website use the same script (directly or indirectly), the same content will be available on both.
For example, for a train timetable service, the times shown will be the same on 15 TV and PC and they will come from the same script.
