The present invention relates to a display apparatus, an information terminal and an information processing method, and particularly relates to a technique effective for viewing content with using a plurality of terminal apparatuses.
In recent years, distribution services that distribute content such as movies and music via the internet have been widely used. For example, Patent Document 1 is known as such a distribution service. Patent Document 1 describes that “there is provided a network terminal system that allows a display apparatus to be shared between a plurality of users while protecting privacy of each user”, and describes a technique that allows the television receiver to be shared between a plurality of users and to be selectively used while protecting the privacy of each user by using a wireless terminal to operate a television receiver.
Patent Document 1: Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. JP-T-2014-080508
However, the above-described technique of Patent Document is insufficient in terms of user-friendliness in various usage environments and usage situations.
For example, in a case where a plurality of users simultaneously share and use a television receiver which is a display apparatus in Patent Document 1, each user subscribed to a content distributor, or the so-called content provider, is likely to have a subscription such as an available service division that differs from another user. For this reason, each user would need to perform, for example, a login operation every time the content to be viewed is switched, causing a problem of poor user-friendliness.
An object of the present invention is to provide a technique in which content and the like can be efficiently provided when a display apparatus is shared with utilizing a plurality of terminal apparatuses, even if the service divisions differ between each user.
The above-described object, other objects and novel features of the present invention will be apparent from the descriptions in the present specification and the attached drawings.
A brief summarized description of a representative embodiment according to the invention disclosed in the present application is as follows.
Namely, a representative display apparatus is connected to two or more information terminals via a first network and is connected to a content distribution apparatus via a second network, the content distribution apparatus configured to distribute content.
This display apparatus includes an information controller, a content controller, an aggregated content generator and a first display. The information controller sends each piece of login information entered from the two or more information terminals to a content distribution apparatus. The content controller obtains pieces of content list information each generated by the content distribution apparatus based on the pieces of login information sent from the content distribution apparatus.
The aggregated content generator generates an aggregated content list in which the pieces of content list information obtained from the content distribution apparatus by the content controller are aggregated. The first display displays the aggregated content list generated by the aggregated content generator.
The content list information is information containing a list of content available for viewing on each of the information terminals connected to the display apparatus via the first network. The aggregated content list is information containing a list of content available for viewing on the two or more information terminals in which the pieces of content list information are aggregated.
In addition, the information controller generates aggregated login information in which the pieces of login information entered from each of the two or more information terminals logging in on a group basis are aggregated, sends the aggregated login information to the content distribution apparatus, receives aggregated service information generated by the content distribution apparatus based on the aggregated login information from the content distribution apparatus, and sends the received aggregated service information to the information terminals.
The aggregated service information sent from the information controller is information indicating an added value obtained when the two or more information terminals log in to the content distribution apparatus on a group basis.
In particular, the aggregated service information received by the information controller includes split payment information as the added value, the split payment information indicating that a viewing fee of the content can be split between the two or more information terminals logged in on a group basis.
A brief description of an effect obtained by the representative embodiment according to the invention disclosed in the present application is as follows.
It is possible to achieve a highly convenient network terminal system.
In the embodiments described below, the invention will be described in a plurality of sections or embodiments if necessary for the sake of convenience. However, these sections or embodiments are not irrelevant to each other unless otherwise clearly specified, and one section or embodiment partially or entirely corresponds to another section or embodiment as a modification, detailed or supplementary description or the like.
In addition, in the embodiments described below, when referring to the number of a component (including number of pieces, numerical value, amount and range), the number is not limited to a specified number and may be less than or greater than this number, unless otherwise clearly specified or unless it is obvious from the context that the number is limited to the specified number in principle.
Further, in the embodiments described below, it goes without saying that each component (including an element step) is not indispensable unless otherwise clearly specified or unless it is obvious from the context that the component is indispensable in principle.
Likewise, in the embodiments described below, when referring to a shape, a positional relation or the like of a component, a substantially approximate shape, a similar shape or the like is included unless otherwise clearly specified or unless it is obvious from the context that the shape, the positional relation or the like of the component differs in principle. The same applies to the above-described numerical value and range.
In addition, in all of the drawings that describe the embodiments, the same members are generally denoted by the same reference symbols, and redundant descriptions are omitted as appropriate.
Hereinafter, embodiments will be described in detail.
The first embodiment will describe a case where a service (hereinafter referred to as IPTV service) for distributing content such as video images, audio and text information via the internet is used by way of example; however, the present embodiment is not limited to such a case.
<Regarding IPTV Service>
The IPTV service is roughly classified into three modes of services that include streaming, download and progressive download. In streaming, items of content data are successively distributed from a server to a client, and the video image, audio or the like obtained through the data received by the client is played back such that the video image, audio or the like is presented to the user. Thus, streaming is characterized in that the user can view the content on a substantially real-time basis when the network has a sufficiently wide band.
In download, the client obtains and accumulates all items of content data from the server in advance, and after accumulation is completed, playback for viewing is performed. Thus, download is characterized in that the user can receive content distribution even if the network does not have a sufficiently wide band and can view the content several times at desired timings when the content does not need to be viewed on a real-time basis by completing distribution of the content data and accumulating the data in advance.
In addition, in progressive download which is a service between these two services, items of content accumulated in the terminal can be successively viewed before distribution of all items of content is completed. In this manner, it is not always necessary to wait for the accumulation to complete, so that it is possible to provide an advantage in which the accumulation time is shortened even if the network does not have a sufficiently wide band. In addition, it is possible to provide an advantage in which the user can view the content several times at desired timings after the accumulation is completed.
In the content distribution service including the IPTV service, a compensation fee is usually charged by a service provider to the user for receiving the distribution service. At this time, the user is registered as an authorized user in advance, and various pieces of information such as a password, name and street address are managed by using an identifier such as an ID as a clue. Note that the password may be biometric information such as a fingerprint.
In a case where a for-pay content is distributed, it is possible to record billing information at the time of accumulation or viewing, and it is confirmed that payment of the compensation fee is possible through a separately designated payment method.
At a stage of using the distribution service, the identifier such as an ID (IDentification) of registration information and the password needs to be verified with management information in order to receive user authentication and make the service available. The authenticated authorized user is usually provided with a content viewing portal screen for selecting and searching the content to be distributed and for selecting other services such as information distribution.
In addition, device authentication is usually performed via a communication prior to the distribution service in order to confirm whether or not the device used by the user is a device recommended by the service provider, confirm whether or not the program received by the distribution service operating in the device is a recommended program, or the like. In this manner, illegal behavior such as unauthorized copying, transferring and modifying which violate laws such as the Copyright Act and unauthorized usage of the content are prevented.
At this time, the content may be encrypted in advance by a common key cryptosystem, and a key for decrypting the encrypted key may be associated with the received content and be separately maintained such that the encrypted key can be decrypted by an authenticated authorized user, an authenticated authorized connection device or an authorized connection device in which an authorized user is authenticated.
In addition, a public key and a private key may be prepared on the connection device side or the service provider with utilizing a public key cryptosystem. The private key may be sent to the connection device during user registration and be utilized for encrypting and decrypting keys in each of the service provider and connection device.
Generally, these keys for decrypting are recorded together with playback conditions such as an expiration date of the content, number of times the content can be played back and the user and device capable of playing back the content. Hereinafter, the key for encrypting will be referred to as an encryption key, and the key for decrypting will be referred to as a decryption key.
In this manner, the IPTV service provider serving as a content or service provider associates user authentication, device authentication and decryption keys to one another in order to safely provide the content distribution service and the like to users and reliably charge the fee.
Thereafter, the user receives distribution of the desired content and correctly receives services such as content playback. Further, in this regard, there may be a case where the user is allowed to maintain the content associated so as to comply with a right for playback corresponding to the copyright of the content.
The user performs playback of the content on a predetermined device with utilizing the content and decryption key obtained in such a manner; however, this is performed under the presumption that the same apparatus is used by the same user.
On the other hand, in a case where the same user possesses a plurality of apparatuses and wishes to play back the same content on a different apparatus, there is an inconvenience in that a fee for the same content is charged again.
For this reason, there is a service that allows the content to be played back on a number of devices within a range permitted by the service provider if the right for playback is held by the same user.
In addition, there is also a service in which a function of an application software purchased and downloaded as in the case of the content is acquired by running the application software in the device. As in the case of the content, there is also a service that allows an authenticated authorized user to download an application to a number of devices within a range permitted by the service provider if the right for download is held by the same user.

Further, the browser engine 502 sends a request message from the external network 105 to the content distribution server 106 via the communication I/F 212 and wireless router 104, requesting resources such as web content that complies with HTTP (HyperText Transfer Protocol).
The content distribution server 106 creates and returns a response message corresponding to the received request message. The returned response message is entered into the browser engine 502 via the external network 105.
An HTML document is embedded in the response message. The HTML parser 503, the database generator 504, the renderer 505 and the image processor 506 of the browser engine 502 work together to generate a browser display screen based on the HTML document, so that the login screen of the content viewing portal is displayed on the display 210 (step S1206).
In the login screen displayed by the above-described processes, the controller 214 notifies login information including the entered username and password to the browser engine 502 by the same operation information as in the process of step S1203 and sends a received character string to the content distribution server 106 as a request message (step S1207).
The content distribution server 106 refers to the user authentication information stored in the user authentication information 407 by the user manager 701 and authenticates the user if the user is an authorized and registered user (step S1206).
Here, in
Subsequently, when authentication in a process of step S1208 is completed, the content manager 702 of the content distribution server 106 returns the content list information to the browser engine 502 as a response message (step S1209).
The content list information sent at this time is information for displaying a list of the content managed by the content manager 702 and includes information for identifying the managed content.
When the browser engine 502 receives the content list information from the content manager 702, the browser engine 502 refers to the content ID for uniquely identifying the content, content description information (genre title, cast, plot and the like), a fee for playing back and viewing the content, a viewing period and the like included in the content list information and displays the content list display screen on the display 210 as shown in

In the content detail display screen shown in
The content selection information includes information for identifying desired content and information for identifying whether the desired content is in HD image quality or in SD image quality as necessary.
The content distribution server 106 generates the key information for decrypting the content identified based on the content selection information and sends the key information to the television receiver 101 (step S1213).
The key information is constituted by the decryption key for decrypting the information of the encrypted content as well as the content ID for each item of content, the expiration date or the number of times the content can be played back, and the like. Note that the step (step S1213) of sending the key information is necessary to encrypt the content and may be omitted if the content does not need to be encrypted.
When the television receiver 101 receives the key information from the content distribution server 106 and completes preparation for receiving the content, the television receiver 101 sends a content distribution start request (step S1214). The content distributor 703 of the content distribution server 106 having received the distribution start request from the television receiver 101 starts the content distribution to the television receiver 101 (step S1215).
When a tap operation is performed on “play” on an operation screen 1213 screen shown in
In the television receiver 101 having received the operation information (playback), the content player 507 performs playback processing of the content. At this time, if there is a decryption key, the decryption key is utilized to decrypt information of encrypted content and start playback of the content (step S1218).
In a case where a stop operation button on the operation screen 1304 shown in
In a case where the content distribution server 106 receives the distribution stop request from the television receiver 101 or the content distribution server 106 detects an end of the content (step S1222), the content distribution server 106 stops distributing the content (step S1223) and sends a content distribution end notification to the television receiver 101 (step S1224).
When the television receiver 101 receives the content distribution end notification, the television receiver 101 stops playing back the content (step S1225). Here, it can be configured such that the television receiver 101 returns to a state before start of content playback when the television receiver 101 stops playback in a process of step S1219.
In addition, in a case where playback is stopped by the process of step S1219, information of the playback stop position of the content is stored in the user profile information of the storage 216 of the wireless terminal 102 as resume information.
Further, in a case where playback operation is performed again via the wireless terminal 102 and playback of the same content is resumed by the same user, the content player 507 of the television receiver 101 can obtain data of the playback stop position from the resume information and resume playback by using the playback stop position as the playback start position.
In addition, the information of the playback stop position of the content can be held by the content distribution server 106. In this case, the content distribution server 106 sends the information of the playback stop position of the content together with the information of the content in the process of step S1215.
In this manner, distribution can be started in the television receiver 101 from the playback start position calculated based on the information of the playback stop position obtained together with the information of the content from the content distribution server 106.
Note that a flow of actions in a case where distribution of the content is received from the content distribution server 106 to playback the content has been described; however, it may be configured such that all items of content data are obtained and accumulated at the timing of the process of step S1215 of
In addition, in the process of the step S1213 of sending the key information, the television receiver 101 can store the key information received from the content distribution server 106 in the storage 216. Alternatively, the key information can be discarded each time and be obtained from the content distribution server at the timing of the process of step S1218 every time the content is played back.
In addition, in a case where the content downloaded from the content distribution server 106 and played back on the wireless terminal 102 is stopped part way through the content, and the user wishes to view the rest of the content on the television receiver 101, the downloaded content can be synchronized between the wireless terminal 102 and the television receiver 101 by the content/application synchronization processor 510 of the television receiver 101 based on the user profile information.

At this time, the notification message to be displayed may include a message 1802 notifying a newly logged-in username and a message 1803 notifying all logged-in usernames.
Subsequently, the controller 214 of the television receiver 101 creates an aggregated content list (step S1708) and displays the aggregated content list display screen on the display 210 (step S1709). The aggregated content list is constituted by the content list information which is sent in a process of step S1209 and is available for viewing by the user of the wireless terminal 102 and the content list information which is sent in a process of step S1407 and is available for viewing by the user of the wireless terminal 103.
As shown in
Note that, in the example of the aggregated content list display screen 1901, an indication 1904 of Titles 1 to 3 indicates content available for viewing by the username: T. Matsu, and an indication 1905 of Titles 4 and 5 indicates content available for viewing by the username: M. Kage. The username: T. Matsu is the user of the wireless terminal 102, and the username: M. Kage is the user of the wireless terminal 103 and the television receiver 101.
It may be configured such that, before aggregating the content list information in a process of step S1708, the television receiver 101 displays a sort process selection screen 2001 shown in
The indication 2004 generates and displays a list of title names rearranged in alphabetical order or the like. The indication 2005 generates and displays a list of usernames rearranged in alphabetical order or the like.
At this time, a message 2002 indicating currently logged-in usernames, that is, usernames whose items of content are aggregated, and a message 2003 describing an action of the television receiver 101 such as “Content which the above users can view will be displayed” may be displayed.
In a case where each user operates the television receiver 101 via the wireless terminals 102 and 103 to end device connection between the wireless terminals 102 and 103 and the television receiver 101, the wireless terminals 102 and 103 are logged out one by one according to the processes of steps S1010 to S1012 which is the action sequence shown in
As shown in
In addition, in a case where the user (M. Kage) logs out while viewing the content associated with the user account of the user (M. Kage) as in the indication 1905 of Titles 4 and 5 shown in
Alternatively, the television receiver 101 may perform controls such that the user can continue to view the content during a certain period such as until the end of the content or until the television receiver 101 is turned off.
Namely, it may be configured such that the television receiver 101 does not send the distribution stop request to the content distribution server 106 (step S1221) until this certain period passes. In addition, it may be configured such that the user can view the content several times during a certain period such as for 24 hours after the other user (M. Kage) has logged out.
Namely, it may be configured such that the television receiver 101 continues to maintain the login information (username and password) of the logged-out user (M. Kage) in the memory 215 during the certain period and sends the login information related to the logged-out user (M. Kage) in a process of step S1705 shown in
It may be configured such that a message 2103 as shown in
In the above-described manner, the content lists associated with the user account of each user can be aggregated and displayed as one aggregated list by the plurality of users respectively using the wireless terminals 102 and 103 to share and simultaneously log in to the television receiver 101.
In this manner, it is possible to improve user-friendliness of the network terminal system.
<Overview>
According to a second embodiment, the wireless terminals 102 and 103 simultaneously log in to the content distribution server 106 via the television receiver 101 to obtain services with an added value, that is, a value-added service from the content distribution server 106.
It is assumed that the value-added service is prepared in advance by the service provider providing the content.
<Example of Actions in Network Terminal System>
The second embodiment will be described with emphasis on differences from the first embodiment. The configuration of the network terminal system, the software configuration of the television receiver 101 and the software configuration of the wireless terminal 102 are the same as those of the first embodiment, and thus, redundant descriptions will be omitted.

<Overview>
The present embodiment will describe a technique in which portions (steps S1001 and S1002) in the actions (steps S1001 to S1009 of
<Example of Actions in Network Terminal System>
In
Note that the “terminal search App” can be achieved by a generally known technique, and thus, illustrations and detailed descriptions will be omitted. The connection request may include information and device ID which allow the user to identify a device having sent the connection request. The information which allows the user to identify the device is, for example, a model name (AB-C1000) of the television receiver 101, and the device ID is, for example, 3D:4F:1E:00:xx:xx and the like.
The wireless terminal 102 having received the connection request determines whether or not the wireless terminal 102 “is connected” to the television receiver 101 in step S3103. If the wireless terminal 102 is connected (YES), the wireless terminal 102 returns a connection status response indicating that the wireless terminal 102 is connected to the television receiver 101 and ends the operation.
On the other hand, if the wireless terminal 102 is not connected (NO), the network connection confirmation screen is displayed on the display 308 and confirms “whether or not to connect” to the user (step S3104).
The network connection confirmation screen 3201 includes a message 3202 indicating that “a connection request has been received from the television receiver”, an option 3203 indicating that “connection approved” and an option 3204 indicating that “connection rejected”.
