Description

[0001] APPARATUS AND METHOD FOR FACILITATING CHANNEL CONTROL ON A PAIRED DEVICE [0002]

The present invention relates to a method and apparatus for interacting with a display device using a portable device, and more particularly relates to channel control for a paired device.

In general, channel switching in a television is enabled by a remote controller. The remote control device is a device for controlling the television. The remote control device enables the user to switch the channel by directly inputting the channel number, and enables the user to search the channel list by sequentially pressing the up / down buttons. In addition, the display device in the remote control device displays the recently viewed channel. Recent advances in the field of handheld control devices make it possible to use smartphones as remote control devices for televisions. By way of example and not limitation, the handheld control device includes smartphones, tablet computers, smart watches, and laptops. The portable control device is installed with the control application program to simulate the remote control device function in the portable control device. By way of example, and not limitation, control applications include "Google TV remote", "LG TV remote", "Xbox Smart glass", "Samsung WatchOn" and "Sony Media remote". The portable control device is referred to as a user control device. The portable control device is hereinafter referred to as a user control device.

Conventional control applications provide channel program thumbnails on the display of the user control device. Often it is required to view a list of previously viewed broadcast channels to switch to previously viewed broadcast channels. During the advertisement time of the first viewed channel, the user searches for the broadcast channel. The user then hopes to switch to the previously watched channel. After a continuous channel change, the user tends to forget the channel number of the first viewed channel. Switching to the previous viewing channel is requested with a single touch on the user control device. It is also required to provide an interface with the history of the channel viewed on the user control device.

In existing systems, channel details are displayed in a web browser of the display device. The existing system provides an interface for displaying thumbnails of the content broadcast on a paired device. However, existing systems do not provide a mechanism to transmit a channel switch command by selecting a thumbnail on the paired device. In addition, existing systems do not provide easy navigation of previously viewed channels.

Although it displays the channel view history in other existing systems, it does not provide a user interface for selecting one of the channel view details. In addition, the existing system does not include a method of displaying the channel view history data together with the meta-data of the channel viewed on the portable device.

In view of the above discussion, there is a need for a method and system for easy channel control and searching in a paired device to provide an easy search for previously viewed channels with a single touch. In addition, the paired device is required to transmit channel viewing details and related metadata information.

One example of a method for facilitating channel control in a paired device is to extract channel metadata information for each broadcast channel displayed on the display device if the display time of each broadcast channel exceeds a predefined time . The method also includes transmitting channel metadata information of each viewed broadcast channel to the paired device. The method includes storing channel meta information of each viewed broadcast channel. The method also includes displaying a plurality of icons on an interactive interface of the paired device. This allows for easy channel control through the interactive interface of the paired device.

One example of a method for facilitating channel control in a paired device includes extracting application information of the applications being viewed on the display device. The method includes sending application information of each application program to the paired device. The method also includes storing the application information in a control application program of the paired device. The method includes displaying a plurality of icons on an interactive interface of the paired device, wherein each icon is based on application information. Through the above method, it is possible to control the application program easily through the interactive interface of the paired device.

A system for easy channel control includes a display device and a paired device. The display device displays at least one of a broadcast channel and an application program. The display device includes a metadata extractor for automatically extracting channel metadata information and application program information. In addition, the display device includes a data synchronizer for transmitting channel metadata information and application program information. The paired device provides control of the viewed channel and the viewed application. The paired device includes a metadata synchronization device for updating the control application with channel metadata information and application program information. The paired device also includes a user interface for displaying a plurality of icons on the paired device.

2 shows a block diagram of a system for easy channel control according to another embodiment of the present invention. The system includes a set-top box 205, a display device 210, and a paired device 280. The display device 210 includes a stream decoder 215, a metadata extractor module 220 (also referred to as a metadata generation module), a channel data setting module 225, A connection detection module 250, a data synchronizer module 245, an application database 230, an RF receiving module 240, and a first communication interface 235a. The paired device 280 may also include a metadata synchronizer module 255, a user interface 275, an RF generator 260, a channel selector 270, a second A communication interface 235b and an application selection module 265. A set top box (STB) 205 delivers stable high-definition content from cable operators and satellites to the display device 210. In one embodiment of the present invention, the STB 205 is connected to an Ethernet cable to provide live-streaming of the content to the display device 210. The stream decoder 215 of the display device 210 decodes the digital signal received at the STB 205.

The main module of the display 210 for easy channel control in the paired device 280 is described below.

Channel Data Setting Module: The channel data setting module 225, which is available for setting the display 210, allows the user to set the minimum viewing time for each broadcast channel among the plurality of broadcast channels received at the STB 205. The minimum viewing time is referred to below as a predefined channel time. The duration for each broadcast channel viewed by the user is referred to as "viewing time ". If the viewing time of the broadcast channel is greater than or equal to the predefined channel time, the broadcast channel content is eligible to be extracted as metadata. If the user has not manually set the predefined time, the channel data setting module 225 sets the default channel time. In the exemplary embodiment, the default channel time is set to 5 minutes.

The metadata extraction module 220 of the display device 210 extracts channel metadata information of a broadcast channel viewed by the user on the display device 210. The broadcast channel metadata information includes, for example, a program name, a channel name, a genre, a keyword, metadata, subtitles, a channel logo, a channel number, parental information, channel snapshots and additional information including advertisements and channel signal strength. The metadata extraction module 220 also checks the settings of the display device 210 through interaction with the channel data setting module 225. The channel data setting module 225 determines whether the broadcast channel is eligible to be extracted as metadata. The metadata extraction module 220 sends channel metadata information to the data synchronization module 245.

The application database 230 displays a plurality of widgets and application programs that can be used in the display device 210. [ The application database 230 retrieves the application metadata of each read application. The contents of the metadata of the application programs include, by way of example and not limitation, information on the application icon, application program name, and application program type. The application program database 230 sends application program metadata information to the data synchronization module 245. The data synchronization module 245 sends channel metadata information and application program metadata information to a plurality of paired devices. The display device 210 communicates with the paired device 280 via the first communication interface 235a and the second communication interface 235b. Communication protocols include, by way of example and not limitation, Bluetooth, NFC and Wi-Fi.

Connection Detection Module: The connection detection module 250 displays a list of connections between the display device 210 and the paired device 280. The paired device may be a remote control device, a smart phone, a tablet and a smart gear. At the same time, there are a plurality of paired devices connected to display device 210. From the available list of paired devices as shown in Table 1, the user can select at least one paired device for displaying metadata information. Display device 210 transmits the channel metadata information to the selected paired device. In addition, the connection detection module 250 determines if a plurality of paired devices connected to the display device 210 have a control application program installed. By way of example, and not limitation, the control applications include "Google TV remote", "LG TV remote", "Xbox Smart glass", "Sony Media remote" and "Samsung WatchOn Application". The metadata information is transmitted to the first group of paired devices in which the control application is installed.

Data Synchronization Device: The data synchronization module 245 transmits channel metadata information to the paired device 280. The data synchronizer 245 interacts with the connection detection module 250 and transmits channel metadata information to the first group of paired devices.

Table 2 shows an example of the viewing time and metadata extraction status for various broadcast channels. The basic channel time of the broadcast channels "MTV", "CNN" and "ZTV" is 5 minutes. In Table 2, the viewing time of "MTV" is 10 minutes, and the viewing time of "CNN" is 5 minutes. The viewing time of "MTV" and "CNN" is equal to or greater than the basic channel time. As a result, the metadata extraction module 220 extracts channel metadata information from "MTV" and "CNN ". However, the viewing time of "ZTV" is 30 seconds. The viewing time of "ZTV" is smaller than the basic channel time. As a result, the metadata extraction module 220 fails to extract the channel metadata information of "ZTV ". Here, 5 minutes set as the basic channel time is illustratively shown for illustrative purposes, and larger or smaller times may be set according to other embodiments.

The paired device 280 is installed with a control application program. The metadata synchronization module 225 continuously receives the channel metadata information from the data synchronization module 245. In addition, the metadata synchronization module 255 checks the new channel metadata information received from the data synchronization module 245. New channel metadata information corresponding to the switching of the displayed content is received at the paired device 280. In addition, the paired device 280 stores the new channel metadata information in the database of the paired device 280. Also, in the paired device 280, the paired device 280 displays new channel metadata information on the interactive user interface 275. The interactive user interface 275 displays channel metadata information for a plurality of broadcast channels and application programs viewed by a user. The channel metadata information corresponding to a plurality of broadcast channels and application programs is displayed on the display screen of the paired device 280 by a plurality of icons. The plurality of icons are arranged according to the order viewed by the user. A plurality of icons are displayed in one of a grid format and a list format. The user can set limits on the number of icons displayed on the interactive user interface 275. [

Corresponding to the user's first icon selection on the interactive user interface 275, the channel selection module 270 fetches the first channel number corresponding to the first icon. The channel selection module 270 sends the first channel number to the RF generation module 260. The RF generation module 260 generates a first RF signal having a particular channel frequency corresponding to the first channel. The first RF signal is received at the RF receiver 240 of the display device. As a result, the currently viewed channel of the display device 210 is switched to the first channel corresponding to the first RF signal. Thus, the system enables navigation to previously viewed channels via the user interface 275. [

If the icon selected on the user interface 275 corresponds to an application program, the application selection module 265 retrieves application program information selected from the metadata synchronization module 255. The application selection module 265 sends application program information from the second communication interface 235b to the first communication interface 235a. Protocols used in the first communication interface 235a and the second communication interface 235b include Bluetooth, NFC, Wi-Fi and other wireless transmission protocols. If the application information is received at the display device 210, the application database 230 checks the corresponding application program identifier (ID) or application program name. The application database 230 opens the corresponding application program on the display device 210 to replace the currently viewed content. Thus, the system enables searching for previously viewed application programs via the user interface 275.

Apart from searching for previously viewed application programs, the system provides a number of control operations for the user. The control operation enables the user to control the display device 210 via the paired device 280. The control operation in the paired device 280 is:

a) providing parental control for the broadcast channel;

b) switching of channels based on advertising information;

c) provide a snapshot of the program on the broadcast channel; And

d) providing channel signal strength information.

In one embodiment of the present invention, provision of parental control for a broadcast channel includes displaying parental rating information for broadcast channels viewed on the paired device. The method also includes enabling the user to block one or more broadcast channels displayed on the paired device based on guardian rating information. Thus, the paired device notifies the display device of channel ID information for one or more blocked channels. A locked icon is displayed with metadata information for each channel viewed on the interactive interface of the paired device. The control application of the paired device enables the user to lock at least one channel on the user interface by clicking a locked icon. Thus, the present invention limits the user from viewing a locked channel.

In another embodiment of the invention, the switching of the channel based on the advertisement information comprises transmitting the metadata information of the advertisement related to the viewed channel to the paired device. Also, the paired device stores the metadata information of the advertisement in the database. The paired device displays the metadata information of the advertisement in a specific color format along with an icon on the interactive interface. The specific color format includes the first color format and the second color format. The first color format indicates the active state of the advertisement in the corresponding channel. The second color format indicates the active state of broadcast contents in the corresponding channel.

In another embodiment of the invention, the control application program enables the paired device to display a plurality of broadcast program snapshots in the channel history tap of the paired device. The paired device updates the channel history tab with a snapshot of the channel's current broadcast program. As an example, the user is watching a live cricket match at ESPN. Thereafter, the user switches the channel to watch an important program. ESPN metadata is displayed on the paired device, and a snapshot of the cricket game is displayed on the Channel History tab. The Channel History tab updates ESPN's snapshot with a score from the cricket game and notifies the user. As such, the user switches to ESPN during a critical event of the event.

In another embodiment of the present invention, the control application program enables the paired device to display channel signal strength information with each icon from a plurality of icons on the interactive interface of the paired device. In addition, the control application dynamically updates the channel signal strength information. For example, a paired device displays a signal strength icon with a channel logo icon. The user examines the icons and switches back to the first channel if the signal strength of the first channel is good.

Figure 3 shows a block diagram of a paired device 300 for easy channel control in accordance with an embodiment of the invention. The paired device 300 is installed with a control application program. The control application program enables the user to control the display device using the paired device 300.

The selection module 355 is also comprised of an application selection module and a channel selection module.

The metadata synchronization module 350 updates the database 320 together with the channel metadata information of the broadcast channel displayed on the display device. Also, the metadata synchronization module 350 receives application program information from the display device. Information corresponding to an arbitrary browsed application program is transmitted to the metadata synchronization module 350 and stored in the database 320. In addition, the paired device 300 displays channel metadata information related to a plurality of broadcast channels and application programs viewed by a user. The paired device 300 displays channel metadata information in a plurality of icons on the user interface 340. In the plurality of icons, each icon corresponds to channel metadata information of another broadcast channel viewed by the user. The plurality of icons are arranged according to the viewing order of the user. In the plurality of icons, each icon corresponds to recently viewed content and metadata information, and the metadata information is displayed with an icon to identify the channels. Generally, logs for recently viewed channels are indicated by icons. Other metadata information displayed on the user interface includes a program name, a channel name, a genre, a keyword, metadata, a caption, a channel logo, a channel number, a parental information, a channel snapshot, and advertisement information.

The application selection module enables a user to select a first icon from a plurality of icons of the user interface 340, wherein the first icon represents the application being viewed. The channel selection module enables selection of a second icon from the plurality of icons of the user interface 340, wherein the second icon represents the viewed channel.

4 is a flow chart illustrating easy channel control in a paired device in accordance with an embodiment of the present invention. The process begins at step 405.

In step 410, the display device determines a transition in one of the broadcast channel and the application program. The broadcast channel is provided by the STB and the viewing of the application is supported by the display application database. The portable paired device generates a command for switching the viewed content. The viewed content may be one of a broadcast channel and an application program. If a change of the broadcast channel is detected, step 415 is performed. Otherwise, step 430 is performed.

In step 415, the viewing time of the recently viewed broadcast channel is determined. A predefined time period is set by the user. The viewing time of the broadcast channel is compared with a predefined time. If the viewing time is equal to or greater than the predefined time, step 420 is performed, otherwise step 460 is performed.

In step 420, the connection detection module of the display device identifies a plurality of paired devices equipped with a control application program. If at least one paired device equipped with the control application program is detected, step 425 is performed, otherwise step 460 is performed.

In step 425, the channel metadata extraction module of the display device will extract metadata information of the recently viewed channel. By way of example, and not limitation, the broadcast channel metadata information includes additional information including program names, genres, keywords, metadata, captions, channel logos, channel numbers, parental information, channel snapshots, and advertisements.

In step 435, the data synchronization module will transmit the extracted metadata information to all the paired devices equipped with the control application program. If the recently viewed content is an application program, metadata information corresponding to the application program is transmitted to the paired device.

In step 435, the metadata information is sent from the channel metadata extraction module to the metadata synchronization module of the paired device. In step 430, if an application program termination is detected, the application database provides all application metadata to the paired device.

In step 440, the metadata information is received through the metadata synchronization module of the connected device. The metadata information may be one of channel information and application program information. An icon is displayed in the control application program of the paired device corresponding to the metadata information. In the above process, a plurality of icons are displayed according to the display list corresponding to a plurality of switching in the displayed contents.

In step 445, the metadata synchronization module checks the new metadata information that has been used. Also, the metadata synchronization module determines whether the display list of the paired device has a space for displaying a newly added icon corresponding to the metadata information. If the maximum limit of the display list is detected, step 450 is performed; otherwise, step 445 is performed.

In step 450, the first icon is deleted from the display list, and the channel list is sorted according to the channel viewing history. The icons corresponding to the channels and the applications are updated in the display list in the respective order of the search history.

In step 455, new metadata information is added recently from this display list. In addition, the user is enabled to select at least one icon from the plurality of icons in the display list of the paired device. Icon selection and navigation of previously viewed channels are also described with reference to FIG. The flowchart ends at step 460.

5 is a flow diagram illustrating a method for searching a previously viewed channel in a paired device in accordance with an embodiment of the present invention. The process begins at step 505.

In step 510, the user selects a first icon from a plurality of icons on the interactive user interface of the paired device. The first icon represents at least one of a first viewing broadcast channel and a viewing application.

In step 515, the channel selection module determines whether the first icon indicates a broadcast channel. The application selection module determines whether the first icon represents an application program. If the first icon indicates a broadcast channel, step 520 is performed, otherwise step 530 is performed.

In step 520, a control signal is generated by the channel selection module in response to the selection of the first icon. The channel selection module extracts channel information including the channel ID and the channel name from the first icon, and generates a control signal corresponding to the channel ID. The control signal is sent to the display device to switch the broadcast channel currently viewed with the selected channel ID. In this scenario, the control signal may be an infrared signal.

In step 525, the RF receiving module of the display device receives the control signal and accordingly switches the current viewing broadcast channel to display the first channel in response to the control signal.

In step 530, the application selection module extracts application information including the application program ID and the application program name from the first icon. If the first icon corresponds to the application program, the application program information is transmitted to the display device using the file transfer protocol.

In step 535, the application database of the display device opens an application program selected to replace the currently viewed content. The flow chart is terminated at step 540.

FIG. 6 illustrates an example of displaying channel metadata information of each broadcast channel viewed in a paired device according to an exemplary embodiment of the present invention. The paired device is provided with a control application program. The metadata information of the broadcast channel is transmitted to the paired device provided with the control application program. The control application provides an interactive user interface 635 on the display of the paired device. For example, the user is viewing the broadcast channel ESPN on the display device 600. The user watches ESPN for duration 't'. Thereafter, the user switches to the CNN broadcast channel. If the duration 't' is greater than or equal to the predefined time, the metadata information of the ESPN is transmitted to the paired device. By way of example, and not limitation, the channel metadata information includes a broadcast channel logo, parental information, and commercial advertisement information.

Channel metadata such as parental information, program information, and channel number are extracted from the channel elementary stream from the display device. The channel logo is detected using an algorithm based on facts with fixed features. In a vidio frame, the logo area is always fixed and does not change over time. Video frames are made from subsets of video broadcasts. In general, the logo in the video is expected to be found in one of the four corners of the frame. In addition, the video frame is divided into four parts. The presence of the logo is identified by determining corner persistence in each frame.

Thus, in the above embodiment, the "ESPN" logo is identified in area 610 of display device 610. The channel logo "ESPN" and other metadata information is extracted and transmitted to the paired device. The "ESPN" logo is displayed as a first icon 625 at the user interface 635 of the paired device. The user can switch to the "ESPN" channel with one touch of the first icon 625. Also, the user can switch from the broadcast channel "CNN" to "MTV ". Since the display time of the broadcast channel "CNN" exceeds the predefined time, the metadata information of "CNN" is extracted from the display device 600a. In the area 620 of the display device 600a, the channel logo of "CNN" is identified. The "CNN" logo is also indicated by a second icon 630 at the user interface 635 of the paired device. The user interface 635 is updated according to all viewed broadcast channels. Thus, the present invention provides a number of icons representing a plurality of previously viewed channels in a paged device.

FIG. 7 shows an example of displaying application metadata information of each application program browsed in a paired device according to another embodiment of the present invention. The control application provides an interactive user interface 735 on the display of the paired device. For example, the user is accessing the "Angry Bird" application from the application database of display device 700. After a certain period of time, the user switches to the broadcast channel "MVI ". According to the above-mentioned scenario, the metadata information of "Angry Bird" is extracted and transmitted to the user interface 735 of the paired device. Accordingly, the metadata of "Angry Bird" is represented by the first icon of the user interface 735. In addition, the user switches from the currently viewed broadcast channel "MVI" to the broadcast channel "CNN ". The metadata information of "MVI" is extracted, and the logo of "MVI" is identified in area 710 of display device 710a. The logo of "MVI" is indicated by a second icon 730 of the user interface 735. Thus, both the application metadata and the broadcast channel metadata are displayed in the user interface 735 according to the order in which they are viewed by the user.

FIG. 8 shows an example of displaying metadata information on another faced device based on the viewing history of another user for the same display device according to an embodiment of the present invention. The channel list is maintained for the user in the user control application of the paired device according to the viewing history of the user. In an exemplary scenario, a first list of metadata information is stored in the user interface 800 of the first paired device, and a second list of metadata information is stored in the user interface 805 of the second paired device. The first list of channel metadata information is based on the channel view history of the first user. The second list of channel metadata information is based on the channel view history of the second user. The first user uses the first paired device to search for channels and application programs on the display device. The second user uses a second paired device to search for channels and application programs on the display device. The first list of channel metadata information includes icons, such as "MTV" 810 and "CNN" 815, The second list of channel metadata information includes icons, such as "ESPN" 820 and "SONY" 825,

In one embodiment, if the display device is restarted, a first list of channel metadata and a second list of channel metadata are maintained at user interface 800 and user interface 805, respectively.

9 illustrates an example of displaying advertisement information together with channel metadata information in a paired device according to an exemplary embodiment of the present invention. In the exemplary scenario, the "MTV" that the user is watching is switched to the "CNN" broadcast channel because of the ad content being played on the broadcast channel MTV. Is displayed on the interface 900. The icon "MTV" 910 is highlighted with a first color indicating that the advertisement is active in the broadcast channel "MTV." CNN "is displayed on the user interface 900 of the paired device. The broadcast channel" CNN "is indicative of a broadcast program. And is highlighted with a second color indicating a state in which the program is active.

Advantageously, the invention protects the user from memorizing the channel number. The user can switch to the previously viewed channel by one touching the channel logo displayed on the paired device. The present invention provides easy identification of broadcast content and application programs along with displayed metadata information. The present invention enables a user to access the watched channel history. Multiple devices can be used at the same time. The present invention enables a parent to lock a broadcast channel and other adult content applications.
