The present invention relates to presentations provided via a network, and more specifically, to providing hyperlinks in presentations viewed remotely.
Sharing presentations via a network such as the Internet takes many different forms. Web conferencing describes online collaborative services including web seminars, webcasts, web meetings, etc. Web conferencing uses Internet technologies to provide services to allow real time, point-to-point and multicast communications from a sender to one or more receivers. Software enabling web conferencing may be run in different ways including: on web browsers, using installed conferencing software on each participant's computer, or via a hosted web service.
It often occurs that viewers of a real time, shared presentation are presented with hyperlinks on screen, often being discussed as a part of the presentation. In order to follow the hyperlinks, the viewers have to either find links themselves or interrupt the presenter to gain access to the links available. For example, a team leader may be reviewing work items in a web based workflow management system and a user may not know what a particular work item is. To find out, the user would need to open a web browser, navigate to the page being presented, and click on the work item to find more information.
Current solutions to open hyperlinks, which are shown in a live presentation of a web browser include the following. A viewer may ask the presenter for a link to the current page being shown by interrupting them on the phone or in person. A viewer may ask for a link to the current page being shown using a web meeting chat. A viewer may search for the page himself, provided he has access to the domain. The presenter may make any web pages featured in the presentation available before the presentation, for example, via email or instant messaging.
YouTube (YouTube is a trademark of Google Inc.) provides a system for adding annotations in the form of cards linking to a website from videos that have been recorded and uploaded. The system allows the user to specify a time in the video where the card should be added. When watching the video, the annotation will appear at the specified time. This requires a user to manually add cards and requires the video to already be on YouTube servers.

The method provides 201 a presentation capable of being transmitted to one or more remote viewing systems as presentation data. In one embodiment, the presentation may be transmitted as a live presentation that is streamed as display frames at a rate per second. In another embodiment, the presentation may be a recording of a previously transmitted live presentation, where the live transmission has been recorded at the presenter computer system as it has been transmitted live and the recording may be transmitted at a later date or dates. In a further embodiment, the presentation may be a pre-recorded presentation that is recorded during production of the presentation for transmission only as a pre-recorded presentation.
The method may determine 202 a display area of the presentation. This may be the window of the presentation shown by the presenter at a given time. In some embodiments, such as live presentations, the contents of the display area may change rapidly (such as by a number of frames per second), whilst in other embodiments, this may remain the same for a longer period of time. In one example, the presentation may be provided from a web browser showing an area of a website and the presentation may scroll through the website or may move between pages of the website, and each time the viewable display area changes the contents of the display area may be updated. If the presentation of the website is a live presentation, the website may be sent as a video of a number of frames per second and may be constantly updated.
For a determined display area, the content may be scanned 203 to identify hyperlinks in the display area. Hyperlinks may be provided in a presentation that may be followed by activating the hyperlink by clicking, tapping, or hovering with a cursor at the anchor of the hyperlink in the presentation. The activation of a hyperlink may navigate or browse to the linked document or another resource. In one embodiment, in which the display area is a display window of a web browser, the hyperlinks may be identified by scraping details of all viewable hyperlinks using a plugin to the web browser.
Link information for the identified hyperlinks may be obtained 204. The link information may include the link destination.
The link information may also include the size and location of the anchor of the hyperlink in the display area of the presentation. The anchor in the presentation may be anchor text or an image. The area of the anchor may be defined by coordinates in the display area of the presentation.
For recorded presentations, the link information may include metadata relating to the location and/or time of the hyperlinks in the presentation, which may enable the relevant hyperlinks to be associated with a display area.
The link information may be provided 205 for transmission in association with the presentation data of the display area. This may be streamed with the presentation data or may be sent separately with a reference to the location or time in the presentation data. The link information may be provided as link objects for transmission that may be used by a viewer computer system for displaying corresponding hyperlinks.
It may be determined 206 if there is a next display area of the presentation. If there is a next display area, the method may loop to process 207 the next display area when this is available. If there is no next display area, the presentation ends 208.
The presenter may change the size or aspect ratio of the display area during the presentation. If this occurs, a corresponding alteration to the position information for hyperlinks displayed as overlays at the viewer computer system may be carried out.
Referring to
The viewer computer system may receive 251 presentation data capable of being viewed as transmitted from a presentation computer system and may receive 252 link information associated with the presentation data. The link information may be received streamed with the presentation data or may be sent separately with a reference to the location or time in the presentation data.
The viewer computer system may generate 253 hyperlinks from the link information received from the presentation computer system for a display area. The link information may be received as link objects that may be used to generate the hyperlinks.
The link information may include destination information that may form the target of the hyperlink.
The link information may also include size and location information of a hyperlink in the display area of the presentation that may be converted to a corresponding size and location of an anchor in the display area of the viewer display area.
For recorded presentations, the link information may include metadata relating to the location and/or time of the hyperlinks in the presentation, which may enable the relevant hyperlinks to be associated with a display area.
The viewer computer system may display 254 a current display area of the presentation data and any associated hyperlinks that are in the display area of the presentation. The hyperlinks may be displayed adjacent the viewer display area, for example in an area of a window adjacent the display as a list of operable hyperlinks. Alternatively, the hyperlinks may be displayed in corresponding size and location over the viewer display area as an overlay that includes activation control of the hyperlinks.
The viewer computer system currently displaying the presentation may display generated hyperlinks in association with the presentation stream such that the viewer can access the hyperlinks within the displayed presentation.
Activation and opening of a hyperlink at the viewer computer system may display the target destination in a number of ways. The target destination may be opened and displayed as a new tab in a window, as a new window, as a transclusion in the presentation display, or any other configurable option. The hyperlink may include a specific instruction on how to open the target destination.
It may be determined 255 if there is a next display area of the presentation. If there is a next display area, the method may loop to process 256 the next display area when this is available. If there is no next display area, the presentation ends 257.
The described method and system identifies hyperlinks currently on view in a presentation and transmits information or objects defining the hyperlinks to displaying components on viewer computer systems. The hyperlink objects are used to create hyperlinks in the display of the presentation at the viewer computer. The size of the hyperlink anchors may be adapted to suit the displayed presentation resolution at the viewer computer system.
This has the benefit that the presentation is not interrupted and websites used in the presentation do not need to be made available prior to the presentation. If a user wants to read more about something on-screen after the presentation they can open the target destination of the hyperlink as it appears and continue watching the presentation enabling them to review the target destination of the hyperlink at a later time.

This embodiment is intended for traditional web browser content and when presenting only the web browser content will be transmitted to the viewers, even if the presenter switches to another application. This is similar to how some screen sharing software applications allow a presenter to choose which application to present to viewers and only that application's content is transmitted.
A link providing component 130 may determine 301 the size of the display area of the presentation window of the web browser. This may be measured in pixels.
Hyperlinks may be identified 302 in the display area. This may identify all hyperlinks in a web page and may determine if each hyperlink is currently viewable in the display area that is the currently presented version of the presentation.
The hyperlinks in a web page may be identified by scraping the website being shown. For example, this embodiment may use a web browser plugin to search or scrape the page source (HTML) of the current page for all the anchor tags (<a> <a/>).
A web page is generally larger than a viewport or display area. A user may navigate by using a scroll bar to access and display off-screen areas. In a presentation, the presenter may navigate around the web page being displayed in the web browser by scrolling up and down and left to right.
The method may find all the hyperlinks on the current web page through scraping, yet only a portion of the web page (the viewport or display area) may be visible at a time. Therefore, it may also be determined which hyperlinks are currently in the display area or viewport and are in view in the presentation. Hyperlinks are not visible when they are not on screen in the browser window.
Link information for each identified hyperlink in the display area may be obtained 303 including a link destination in the form of a URL.
In this embodiment, the hyperlinks are to be overlaid on the displayed presentation at the viewer computer system and therefore the method obtains 304 position information of the hyperlink in the display area and details of the anchor area of the hyperlink. For example, the hyperlink may be a string of text with the anchor area being the area of the text. In another example, the hyperlink anchor may be an image and the anchor area may be the shape of the outline of the image.
In this way, the link information may be obtained and preserved for currently viewable hyperlinks in the display area. This data may be saved 305 in a local cache 306 as an object together with or including the position of the link in the display area. The method may continue to identify hyperlinks in a current display area such that the link objects in the local cache 306 are updated as the presentation runs.
The presentation data may be uploaded or transmitted 308 for a current display area and, as it transmits, the method may determine 309 if there is currently data in the local cache 306 for the display area being uploaded or transmitted. If there is no data in the local cache, the method may continue to transmit 308 presentation data whilst determining if there are link objects for a next content of the display area.
For a real time presentation, the local cache 306 may be checked at the same rate as the video being uploaded. So if the presentation video is at 28 frames per second (fps), the local cache 306 may be checked and updated 28 times per second.
If there is one or more link object in the local cache 306 for a display area content, the link objects may be uploaded or transmitted 310 with the presentation data to all the viewers. The method may then continue to transmit 308 a next display area content and newly added link objects from the local cache 306.
For this embodiment, the link objects do not require time stamps as the automated process to collect the video data (the images to transmit) and the display area link objects, does so sequentially and transmits them at the same time. This may be as a pair or as a single piece of data. This means that the viewer computer system may receive a single piece of data or, if a pair, both pieces of data at once and so process them as a linked pair.
Referring to
A link receiving component at a viewer computer system may determine 351 a size of a viewer display area window at the viewer computer system 150. The link receiving component 170 may receive 352 presentation data with any link objects for a current content of a display area from the presenter computer system 110.
The presentation data and link objects may be received sequentially as a pair or as a single piece of data. This means that the viewer computer system may receive a single piece of data or, if a pair, both pieces of data at once and so process them as a linked pair.
It may be determined 353 if there is any difference to currently overlaid hyperlinks in the current content of the display area of the displayed presentation. If there is no difference, the method may wait to receive a next display area content presentation data with link objects from the presenter computer system.
This is an ongoing check that checks at the same rate as the frames per second as the only time that overlay may change is between frames.
If there is a difference, the method may remove 354 all current overlays. The method may calculate 355 coordinates of a new overlay for providing a hyperlink at the viewer computer program and may create and draw 356 the new overlay on the displayed presentation 161.
The overlay provides a hyperlink at the corresponding location on the display area 162 of the displayed presentation 161 to that of the original link in the display area 122 of the presentation 121 at the presenter computer system 110. The hyperlink at the viewer computer system 150 may be activated by clicking directly on the displayed presentation 161 to open the hyperlink. The hyperlink may be opened in a separate window of a web browser, a separate tab, or other configured location at the viewer computer system 150.
If the method does not overlay the hyperlinks on top of the presentation, a section may be available on the display component with a list of currently visible hyperlinks in the display area. This could be in the form of the text that is visible on screen and have the URL alongside each, for example,
In another embodiment, a real time presentation as described in the example illustrated by
In this embodiment, a recording component may be provided at the presenter computer system 110 that may be part of the presentation component 120 or a separate component.
The recording component may capture the link information together with the presentation data and it may be recorded as a single data item or data pair. The recording component may record a timestamp of each hyperlink's link information in the presentation stream to ensure it is associated with a correct display area content of the presentation.
When transmitting a recorded real time presentation, the position of the hyperlinks, the time they are in the display area, and the destination they point to may be stored alongside the recorded presentation data and when the presentation data is played back the same formulas could be applied to draw the links that are used for real time transmission.
On the viewer computer system 150, the displaying component 160 may include the link receiving component 170 for receiving and drawing overlays for the hyperlinks.
In a further embodiment, the presentation 121 may be pre-recorded and is recorded during production of the presentation for transmission only as a pre-recorded presentation (i.e. not a recording of a real time presentation).
This embodiment requires a method of storing metadata regarding the hyperlinks alongside the presentation and when played at a viewer computer system 150, the displaying component 160 may read and render the links on top of the presentation in the same way as described for real time presentations. The metadata may include: the destination information of the hyperlink in the form of the URL the link points to; coordinates of the hyperlink position; and the time period the hyperlink needs to be displayed in the presentation.

The link component 170 may include a viewer display area component 470 for determining a size of a display area at the viewer computer system 150 and the link displaying component 174 may include a conversion component 482 for converting the position information to a scale and aspect ratio of the display area at the viewer computer system 150.
The link displaying component 174 may include a current overlay checking component 483 for checking if a current overlay has been updated and an overlay updating component 484 for updating overlays.
The link providing component 130 of the presenter computer system 110 and the link component 170 of the viewer computer system 150 may be provided by various implementations.
In one example, the presentation component 120 and the displaying component 160 may be web browsers and the link providing component 130 and the link component 170 may be plugins to the web browsers.
In another example, the presentation component 120 and the displaying component 170 may be web service conferencing application and the link providing component 130 and the link component 170 may be extensions to the web service.
In a further example, the presentation component 120 and the displaying component 170 may be downloaded conferencing applications and the link providing component 130 and the link component 170 may be extensions to the applications. This implementation may perform all the actions by loading the URL in its own application and scraping the links in the same method as described above. This may include a mobile application for a viewing mobile device.
A specific example embodiment is now described with the presentation component 120 in the form of a web browser. A web browser plugin may use a library such as jQuery (jQuery is a trademark of JS Foundation, Inc.), which is a cross-platform JavaScript (JavaScript is a trademark of Oracle Corporation) library designed to simplify the client-side scripting of Hypertext Markup Language (HTML). As jQuery is a JavaScript library, a native JavaScript implementation may be produced as an alternative.
The HTTP links in a web page used for a presentation by the web browser may be provided within an anchor element where an anchor element is a piece of text that marks the beginning and/or end of a hypertext link.
For example, an anchor element may be:
The tag <a begins the anchor element which has a single property for the linked resource (URL) which is set using the href=www.google.co.uk key value pair. The text shown on the website is contained between the opening <a> tag and closing </a> tag.
The plugin may work out if the links are currently viewable on the display area using JQuery/JavaScript and only these links may be preserved. For example, this may be done by using Element.getBoundingClientRect( ) method that returns the size of an element and its position relative to the viewport.
Each preserved link and its corresponding position (x,y) may be sent as a JavaScript Object Notation (JSON) object to each of the viewing clients. They may be sent separately or with the presentation data, such as video packets.
The viewing client's link receiving component may read the JSON data and scale the coordinates received based on the aspect ratio and size of the display in use at the viewer client. This then allows the displaying component to overlay an HTTP link on the presentation such as a video feed. The hyperlinks may be provided such that a client can click directly on the hyperlinks that appear on the screen, as if they are interacting directly with the presenter's computer, for example, opening the links in a new tab in the browser.
The described method sends the JSON link data along with a video stream such that the client's displaying component of the presentation software can process it to allow users to click directly within a live video to open an HTTP link.
Referring to
The displayed presentation 161 is displayed with a resolution of x2 by y2 with the corresponding link 560 provided by the described method in the corresponding location on the displaying component 160. The displaying component 160 may include a comments pane 162 for sending and receiving comments to and from the presenter and other participants in the presentation.
The calculation required to scale the size and position of the link overlay that is placed on top of the presentation is as follows.
The Presenter Side Window has the dimensions: x1=1920 Pixels, y1=1200 Pixels.
The position of the link is: Screen Link Position 700×550, Box Width: 100 Pixels, Box Height: 20 Pixels.
The Viewer Side Window has the dimensions: x2=1200 Pixels, y2=600 Pixels.
Screenshare Width(Pixels)/Resolution Width(Pixels)=Width Scale Factor
Therefore, the Width Scale Factor in this example is x2/x1=1200/1920=0.625
Screenshare Height(Pixels)/Resolution Height(Pixels)=Height Scale Factor
Therefore, the Height Scale Factor in this example is y2/y1=600/1200=0.50
Original Screen Link Position Horizontal*Width Scale Factor=New Screen Link Position Horizontal. Therefore, 700*0.625=437.5
Original Screen Link Position Vertical*Height Scale Factor=New Screen Link Position Vertical. Therefore, 550*0.5=275
The New Link Position=438×275 Pixels in the Viewer Side Window.
The size of the link box may also be calculated.
Box Width*Width Scale Factor=New Box Width→100*0.625=62.5
Box Height*Height Scale Factor=New Box Height→20*0.5=10

By way of example only, storage system 634 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 618 by one or more data media interfaces. As will be further depicted and described below, memory 628 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.
Program/utility 640, having a set (at least one) of program modules 642, may be stored in memory 628 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules 642 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.

A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
Cloud Computing
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.
