The present invention relates to a method and apparatus for selecting one of a plurality of video channels for viewing.
In a conventional television system, a plurality of channels are utilized to broadcast, simultaneously, a plurality of programs to a television set. A user is then able to view any one of the plurality of channels received by the television. Further, the user may utilize personalized or virtual channels. The user may, for example, use a remote control to select between the channels.
However, with the increasing number of channels available to a user, it is increasingly difficult for the user to browse through the channels quickly. For example, a user may wish to browse through other channels during commercial breaks and then return to the main channel quickly. This is tedious and time consuming as the number of channels increase. Traditionally, the user remembers the channel number of the current channel in order to quickly return to it once he has finished browsing. Simple mechanisms for returning to the current channel like, for example, pressing a “Previous Program” key or “Alternate Channel” key are effective if the user has only browsed one other channel. However, these mechanisms are not effective when the user has browsed more than one other channel. Other mechanisms, such as the Electronic Program Guide or the “P+”, “P−” keys can be used but do not enable the user to return to their current channel with a single key press.
There exists a method of bookmarking channels, in which a user can select a channel to be bookmarked. The bookmarked channels can then be recalled in the future so that the user is not required to remember the numbers associated with the channels, and is not required to browse the channels to find one of interest.
One known method for bookmarking channels can be found in the patent application WO 9737490. In this disclosure, programs or channels are bookmarked for later selection. At any time while watching the television, the viewer can bookmark programs or channels to which he or she wants to return quickly and/or at a later time by pressing a button on a remote control. When a channel or program is bookmarked, a checkmark is shown in the corner of the screen to indicate that the program is marked. The checkmark only remains visible for a short period of time. Furthermore, when a viewer switches channel, the checkmark disappears. The result of bookmarking more than one channel is that each bookmarked channel is added to a list. Then, when the user wishes to return to a bookmarked channel, they are required to press a Recall button. Upon pushing the recall button, the first bookmarked channel is recalled. The user is then required to press the recall button again to retrieve the second bookmarked channel and so on.
Further examples of known methods can be found in the patent applications US 2002/0075408 and WO 00/62533.
These known methods for selecting a preferred video channel for viewing require the user to browse through a list of bookmarked channels. This may be time consuming if the user has bookmarked many channels.
The present invention seeks to provide a simplified method for selecting one of a plurality of video channels for viewing that overcomes the disadvantages associated with existing methods. In particular, the present invention seeks to provide a method that enables the user to quickly return to a previously bookmarked video channel without the need to browse through all bookmarked video channels.
This is achieved, according to one aspect of the present invention, by a method for selecting one of a plurality of video channels for viewing, the method comprising the steps of: bookmarking a specific one of a plurality of video channels, displaying an object representing said bookmarked video channel, and selecting a displayed object to select said bookmarked video channel.
This is also achieved, according to a second aspect of the present invention, by an apparatus for selecting one of a plurality of video channels for viewing, the apparatus comprising: input interface means for enabling bookmarking of a specific one of a plurality of video channels, display controller means for enabling display of an object representing said bookmarked video channel, and wherein said input interface means and display controller means enable selection of a displayed object to select said bookmarked video channel.
In this way, a video channel is bookmarked to be returned to at a later time. The objects representing each of the bookmarked video channels are displayed until they are removed. This means that the object is displayed even when the program or channel being watched is not the bookmarked program or channel. This allows the user to quickly return to a previously bookmarked program by making a single selection (for example, by pressing a key or pointing and clicking on the required object). Also, since the displayed object represents the bookmarked video channel (for example, the object may be a logo associated with the bookmarked channel), the user is reminded of the content of the bookmarked video channel.
In an embodiment, only the objects representing channels not being shown are displayed to minimize the number of objects displayed and to improve navigation between the channels.
The step of displaying an object may comprise the step of: displaying the object as an overlay of a currently viewed video channel. In this way, the bookmarked video channel is displayed above the main video of the current video channel (like an On-Screen Display (OSD)). This means that the user can continually monitor the bookmarked video channels until a bookmarked video channel is removed. The user is therefore only required to make a single selection to return to a bookmarked video channel and is not required to first recall all bookmarked video channels. Furthermore, the user is able to bookmark video channels in normal viewing mode and does not need to stop viewing the current program to use a selection feature such as an EPG.
The step of bookmarking at least one of a plurality of video channels may comprise the step of: automatically bookmarking a currently viewed video channel when the currently viewed video channel has been viewed for a time period. In this way, the user is not required to press a button to bookmark the currently viewed video channel. Instead, the user can continue to view the current program without interruption.
The method may further comprise the step of: removing the displayed object upon selection of the object. In this way, the user can update the bookmarked video channels that they no longer wish to be bookmarked. The displayed objects are therefore kept to a minimum and a user can more easily select the required bookmarked video channel from the objects that are displayed.
The method may further comprise the step of: removing the displayed object if not selected for a time period. In this way, the user is not required to press a button remove a currently bookmarked video channel.
For a more complete understanding of the invention, reference is made to the following description in conjunction with the accompanying drawings, in which:
With reference to
Operation of the apparatus 100 of
With reference to
The input interface means 108 enables bookmarking of at least one of a plurality of video channels. In other words, a user is able to bookmark at least one of a plurality of video channels via the user interface means 108.
For example, when the display means 112 is showing a video channel of interest to the user, the user inputs a signal into the input interface means 108 via the second input terminal 106. The user may input a signal by using special keys on a remote control, for example. Alternatively, the user may use a favorite list or a history view to input a signal. When a signal is input into the input interface means 108 via the second input terminal 106, the input interface means 108 inputs the received signal into the display controller means 104.
The display controller means 104 then bookmarks the video channel currently received via the first input terminal 102 (i.e. the currently viewed video channel). The display controller means 104 inputs the bookmarked video channel into the storage means 114. The storage means 114 stores the bookmark for later retrieval.
The display controller means 104 may also automatically bookmark a currently viewed video channel when the currently viewed video channel has been viewed for a certain time period. A user is therefore given the possibility to bookmark a video channel and/or a video channel may be bookmarked automatically after a user views a video channel for a certain period of time.
The display controller means 104 enables display of an object representing each of the bookmarked video channels. For example, the display controller means 104 inputs the currently viewed video channel (received via the first input terminal 102) and an object representing each of the bookmarked video channels into the display means 112 via the output terminal 110.
The display means 112 then shows the currently viewed video channel and also displays an object representing each of the bookmarked video channels as an overlay.
An example of a display by the display means 112 is shown in
In an embodiment of the present invention, the display controller means 104 enables display of the object only when the bookmarked video channel represented by the object is not currently selected for viewing. In other words, the display controller means 104 only enables display of the object when the currently viewed video channel is not the same as the bookmarked video channel. In this way, the display means 112 displays an object representing each of the bookmarked video channels (except the currently viewed channel).
The input interface means 108 and the display controller means 104 enable selection of a displayed object to select the bookmarked video channel. In this way, a user is able to select a bookmarked video channel from the objects displayed by the display means 112.
For example, when the user wishes to select a bookmarked channel from the objects displayed on the display means 112, the user inputs a signal into the input interface means 108 via the second input terminal 106. The user may input a signal by using special keys on a remote control, for example. Alternatively, the user may input a signal by pointing and clicking on-screen or via a touch-sensitive screen. When a signal is input into the input interface means 108 via the second input terminal 106, the input interface means 108 inputs the received signal into the display controller means 104.
The display controller means 104 then retrieves the selected bookmarked video channel via the first input terminal 102 and the selected bookmarked video channel is then displayed. In this way, a user is able to quickly select and view a bookmarked video channel.
Upon selection of the object the display controller means 104 removes the displayed object. In this way, the display means 112 no longer displays the object representing the selected bookmarked video channel. The display means 112 may continue to display an object representing each of the other bookmarked channels.
The display controller means 104 may also remove a displayed object if not selected for a time period. In this way, only objects representing the most recently viewed bookmarked video channels are displayed on the display means 112.
