20140282781
This application claims the benefit of Indian Patent Application Filing No. 1073/CHE/2013, filed Mar. 14, 2013, which is hereby incorporated by reference in its entirety.
This invention generally relates to interactive content methods and devices and, more particularly, to methods for processing interactive content and for end user management of interactive content and devices thereof.
In a typical digital broadcast television (TV) scenario, a service provider may be mixing multiple types of content, such as video, audio, and interactive-data, and broadcasting it to users. Each of the types of content which are being mixed and provided dynamically may change over time. For example, the service provider may stop sending some types of content, modify the existing content, and/or completely replace the content with a new content. In each of these scenarios, the end user may be losing content which the user may later have an interest in accessing.
Unfortunately, currently end users are not able to classify, manage, and later access interactive content based on their preference. Instead with existing solutions at most end users can simply record all interactive content as part of a digital video recording (DVR) system integrated with receiver stack. However, these DVR systems do not allow a user to categorize and store interactive content based on user preference. Other current existing solutions allow caching/storing of a portion of provided interactive content, but the portion which is cached or stored is controlled by the broadcaster rather than end user. Additionally, the storage life of this content is solely decided by the broadcaster.
A method for managing interactive content includes initiating by an interactive receiver device at least one of one or more widget applications. A list of available interactive content previously received and stored from a broadcast stream by the interactive receiver device is received by the interactive receiver device based on the initiated one of the widget applications. An item of interactive content is selected by the interactive receiver device from the received list of available interactive content. The selected item of interactive content is received and provided by the interactive receiver device.
A non-transitory computer readable medium having stored thereon instructions for managing interactive content comprising machine executable code which when executed by a processor, causes the processor to perform steps including initiating at least one of one or more widget applications. A list of available interactive content previously received and stored from a broadcast stream is received based on the initiated one of the widget applications. An item of interactive content is selected from the received list of available interactive content. The selected item of interactive content is received and provided.
An interactive receiver device includes at least one of configurable hardware logic configured to implement or a processor configured to execute programmed instructions stored in a memory including initiating at least one of one or more widget applications. A list of available interactive content previously received and stored from a broadcast stream is received based on the initiated one of the widget applications. An item of interactive content is selected from the received list of available interactive content. The selected item of interactive content is received and provided.
A method for processing interactive content includes obtaining by a broadcaster server interactive content from one or more content providers. One of one or more content types for the obtained interactive content is identified and metadata associated with the identified one of one or more content types is identified by the broadcaster server. The obtained interactive content is transformed by the broadcaster server into a standard format based on the identified one of one or more content types and the metadata associated with the obtained interactive content. The transformed interactive content is transmitted by the broadcast server with a broadcast stream.
A non-transitory computer readable medium having stored thereon instructions for processing interactive content comprising machine executable code which when executed by a processor, causes the processor to perform steps includes obtaining interactive content from one or more content providers. One of one or more content types for the obtained interactive content is identified and metadata associated with the identified one of one or more content types is identified. The obtained interactive content is transformed into a standard format based on the identified one of one or more content types and the metadata associated with the obtained interactive content. The transformed interactive content is transmitted with a broadcast stream.
A broadcast server device includes at least one of configurable hardware logic configured to implement or a processor configured to execute programmed instructions stored in a memory includes obtaining interactive content from one or more content providers. One of one or more content types for the obtained interactive content is identified and metadata associated with the identified one of one or more content types is identified. The obtained interactive content is transformed into a standard format based on the identified one of one or more content types and the metadata associated with the obtained interactive content. The transformed interactive content is transmitted with a broadcast stream.
This technology provides a number of advantages including providing methods, non-transitory computer readable media, and devices that enable effective processing of interactive content and end user management of interactive content. With this technology, interactive content can be selectively stored based on user preferences and presented by a receiver in a television network. Additionally, this technology allows for simultaneous presentation of stored interactive content with a presentation from the broadcast stream. For example, the stored interactive content can be displayed using a widget application while watching a live TV broadcast. Additionally, this technology allows an end user to set a time period for how long different types of interactive content are stored. For example, an end user may set an infinite duration for interactive content comprising recipe information, while setting a two day time period for interactive content comprising weather or news. Further, this technology enables an end user to build and customize a hierarchal list or catalog to further classify the different types of categories of interactive content which is stored. This technology also enables an end user to push stored interactive content to other connected devices.

An exemplary method for obtaining and installing one or more widget applications will now be described with reference to
In step 102, the interactive receiver device 14 provides a selection of one or more of the available widget applications to the content metadata server 16, although other manners for selecting widget applications for downloading can be used. In response to the selection, the content metadata server 16 provides the selected one or more available widget applications 74 to the interactive receiver device 14 for downloading.
In step 104, the interactive receiver device 14 downloads the selected one or more widget packages with widget applications 74 from the content metadata server 16, although other manners for downloading the widget packages can be used. In this example, the widget packages include widget applications and related metadata, although the widget packages could include other types and numbers of applications and data.
An exemplary method for storing interactive content will now be described with reference to
In step 202, the interactive receiver device 14 determines whether a type of content for the interactive content in the broadcast stream matches a type of content associated with any of the widget applications 74 downloaded by the interactive receiver 14. If in step 202 the interactive receiver device 14 determines the type of content for the interactive content in the broadcast stream does not match a type of content associated with any of the widget applications 74 downloaded by the interactive receiver 14, then the No branch is taken back to step 200 to continue to monitor the broadcast stream. If in step 202 the interactive receiver device 14 determines the type of content for the interactive content in the broadcast stream does match a type of content associated with any of the widget applications 74 downloaded by the interactive receiver 14, then the Yes branch is taken to step 204.
In step 204, the interactive receiver device 14 stores the received interactive content in memory 36 based on the match of the type of interactive content which is received and the registered preferences for one or more particular types of interactive content, although the received interactive content could be stored in other locations, such as the content metadata server device 16 by way of example only. Additionally, the interactive receiver device 14 generates a list of the stored interactive content for each of the downloaded widget applications 74 associated with the stored interactive content, although other manners for cataloging the stored content can be used. With this technology, the interactive receiver device 14 also may customize the manner in which the lists or catalogs are created. The interactive receiver device 14 could analyze the received interactive content and create a hierarchical list or catalog of the stored interactive content for each of the widget applications. For example, the list or catalog for interactive content comprising recipes might be a hierarchical list having a first level on the list comprising: breakfast recipes, lunch recipes and dinner recipes and then under breakfast recipes there may second level on the list comprising: breakfast baked good recipes; breakfast egg recipes; and breakfast drink recipes, although other types of lists and catalogs arranged in other manners can be used.
In step 206, the interactive receiver device 14 may also obtain from memory 36 stored default annotations associated with the type of interactive content which was received and is being stored, although the default annotations can be obtained in other manners. The interactive receiver device 14 stores the obtained default annotations with the stored interactive content.
In step 208, the interactive receiver device 14 also may optionally obtain additional annotations associated with the type of interactive content which was received and is being stored. In this example, the additional annotations are obtained by the interactive receiver device 14 via user input through the input device 35, although other manners for obtaining the additional annotations could be used.
In step 210, the interactive receiver device 14 determines whether a set time period for any of the stored interactive content associated with any of the selected and downloaded widget applications has expired. For example, the interactive receiver device 14 may determine that stored interactive content on sporting news should be deleted from storage once a week, while interactive content relating to recipes might have an infinite storage life, although other manners for determining and managing a life span of stored interactive content can be used. The set time period for each type of interactive content can be set and adjusted by the interactive receiver device 14.
If in step 210 the interactive receiver device 14 determines the set time period for any of the stored interactive content associated with any of the selected and downloaded widget applications has not expired, then the No branch is taken back to step 200 to continue to monitor the broadcast stream. If in step 210 the interactive receiver device 14 determines the set time period for any of the stored interactive content associated with any of the selected and downloaded widget applications has expired, then the Yes branch is taken back to step 212. In step 212, the interactive receiver device 14 deletes the stored interactive content whose set time period has expired from memory 36 or from wherever the stored interactive content was maintained and then returns to step 200.
An exemplary method for retrieving and presenting interactive content will now be described with reference to
In step 302, the interactive receiver device 14 may determine whether a set time period for any of the stored interactive content associated with any of the selected and downloaded widget applications has expired. For example, the interactive receiver device 14 may determine that stored interactive content on sporting news should be deleted from storage once a week, while interactive content relating to recipes might have an infinite storage life, although other manners for determining and managing a life span of stored interactive content can be used. The set time period for each type of interactive content can be set and adjusted by the interactive receiver device 14.
If in step 302 the interactive receiver device 14 determines the set time period for any of the stored interactive content associated with any of the selected and downloaded widget applications has not expired, then the No branch is taken to step 306. If in step 302 the interactive receiver device 14 determines the set time period for any of the stored interactive content associated with any of the selected and downloaded widget applications has expired, then the Yes branch is taken to step 304. In step 304, the interactive receiver device 14 deletes the stored interactive content whose set time period has expired from memory 36 or from wherever the stored interactive content was maintained and then proceeds to step 306.
In step 306, the interactive receiver device 14 receives a list of available interactive content previously received and stored from the broadcast stream based on the initiated one of the widget applications. The interactive receiver device 14 displays the list of available interactive content on the display device 38, although other manners for presenting the list or other catalog of available interactive content can be used.
In step 308, the interactive receiver device 14 receives via the input device 35 a selection of one of the items of interactive content from the received list of available interactive content, although other manners for receiving a selection of an item of interactive content could be used. By way of example only, the a request for an item of interactive content from the received list of available interactive content could be received from another computing device 17 in communication with the interactive receiver device 14.
In step 310, the interactive receiver device 14 obtains the selected item of interactive content from memory 36 or other location, such as content metadata server device 16 by way of example only, although the selected item of interactive content could be obtained from other locations. Additionally, the interactive receiver device 14 obtains metadata associated with the selected item of interactive content from the content metadata server device 16, although the metadata could be obtained in other manners.
In step 312, the interactive receiver device presents the selected item of interactive content on the display device 38 using the obtained metadata and the presentation module 64, although other manners for presenting the selected item of interactive content could be used. Optionally, the interactive receiver device 14 could present other content simultaneously with the selected item of interactive content, such as with a television program in the broadcast stream. Additionally and by way of example only, the interactive receiver device 14 could obtain and provide the selected item of interactive content to the computing device 17.
An exemplary method for processing interactive content will now be described with reference to
In step 402, the broadcast server device 12 identifies the type of content obtained from the interactive content provider device 22, although the type of interactive content can be determined in other manners. Additionally, the broadcast server device 12 obtains metadata associated with the type of content from the content metadata server 16 originally provided by the broadcast server 16, although the metadata can be obtained in other manners and from other sources.
In step 404, the broadcast server device 12 may transform the obtained interactive content into a standard format based on the identified type of content and the obtained metadata associated with the obtained interactive content, although the interactive content may be transformed into other formats or may not undergo any transformation.
In step 406, the broadcast server device 12 transmits the transformed interactive content with the broadcast stream to the interactive receiver device 14, although the transformed interactive content and/or broadcast stream can be provided to the interactive receiver device 14 in other manners, such as via a broadband connection by way of example only.
Accordingly, as illustrated and described with reference to the examples herein, this technology provides methods, non-transitory computer readable media, and devices that enable effective processing of interactive content and end user management of interactive content. With this technology, interactive content can be selectively stored based on user preferences and presented by a receiver in a television network. Additionally, this technology allows for simultaneous presentation of stored interactive content with a presentation from the broadcast stream. Additionally, this technology allows an end user to set a time period for how long different types of interactive content are stored. Further, this technology enables an end user to build and customize a hierarchal list or catalog to further classify the different types of categories of interactive content which is stored. This technology also enables an end user to share stored interactive content to other connected devices.
