Abstract
An IPTV may be controlled in part by a second user consumer electronic (CE) device such as a personal digital assistant (PDA) or laptop computer. The IPTV obtains system credentials from a management server to access multiple content servers, and the second CE device can browse Internet content available to the IPTV by accessing a proxy server, which coordinates with the management server and content serves to obtain necessary credentials and information for the second CE device.
Description
- The present application relates generally to controlling an IPTV using a second device.
- Internet access through TVs is typically provided by essentially programming the TV (often referred to as an Internet Protocol TV, or IPTV) as though it were a computer executing a browser. Such Internet access is thus uncontrolled except as a firewall or filtering program might block certain sites.
- As understood herein, uncontrolled Internet access may not be desirable in the context of a TV. A firewall or filtering program may not always be installed on the TV and even when one is installed, access remains much more uncontrolled than conventional TV programming traditionally has expected. Also, a locally installed filter can be unloaded or defeated by a user.
- Accordingly, uncontrolled Internet access has several drawbacks. From a viewer's standpoint, exposure to inappropriate subject matter particularly when young viewers are watching is one concern; a much lower threshold of quality screening is another. That is, while many TV shows might not be widely considered as “quality” shows, nonetheless a TV program is usually much more selectively screened than, say, an Internet video. The expectations of TV viewers for such higher level quality screening as a consequence cannot be met by simply providing unfettered Internet access through the TV. Furthermore, TV-related entities, from content providers, manufacturers, and carriers, in most cases derive no benefit from the extension of TV to the Internet, such as, e.g., might be derived, as understood herein, by pay-per-view based on one or more options.
- As further recognized herein, a user might happen to want to control an IPTV using a second device while the IPTV is executing its usual functions. This may be, e.g., because the second device has a convenient user interface or user input device, or because a second person may wish to browse Internet content available to the IPTV while another person is watching or otherwise controlling the IPTV.
- According to present principles, a user can exploit a second device to view, browse and navigate data service offerings by service providers on an IPTV system and have a main IPTV client play the selected offerings.
- Accordingly, a system is disclosed for enabling a user to use a control device to browse assets and select an asset to have a main Internet Protocol TV (IPTV) client play the content. In one aspect the system includes an Internet Protocol TV (IPTV) client device including an IPTV client processor controlling a video display to present content thereon. The system also includes a control device including a control processor and a management server communicating with the IPTV client over the Internet. The management server and IPTV client communicate with at least one content server such that the content server provides audio video content to the IPTV client for presentation of the content on the video display of the IPTV client. The system further includes a proxy server communicating with the management server and the control device.
- The IPTV client sends login information to the management server which returns to the IPTV client a user token that must subsequently be presented by the IPTV client to a the content server to obtain content from the content server. The management server receives and stores a local IP address of the IPTV client. Responsive to the control device sending a request to the proxy server for an executable utility, the proxy server returns the utility to the control device. Further, the control device, executing the utility, prompts a user to input to the control device login information. The proxy server, responsive to reception of correct login information from the control device, returns the local IP address of the IPTV client to the control device. In turn, the control device uses the local IPTV address to access the IPTV client directly to request information about the IPTV client, which information is returned from the IPTV client to the control device such that the local address of the IPTV client need not be globally addressable. Also the control device sends the information about the IPTV client to the proxy server, requesting a list of services available to the IPTV client from one or more content servers. The proxy server relays the request for a list of services to the management server, which returns the list to the proxy server, with the proxy server in turn sending the list to the control device for presentation of information on the video display. Responsive to a user selection of an element on the list, the control device sends a request for a software asset corresponding to the element to the proxy server. The proxy server requests a service login of the content server providing the asset, and the content server provides to the proxy server a list of assets or categories or services which relays the list to the control device, which is presented on the video display of the control device so that the user can navigate to enter a selection. Responsive to the selection the control device sends a command to the IPTV client to play the selection.
- In some embodiments the IPTV client requests of the management server information about the selection received from the control device. The information is returned from the management server to the IPTV client to enable the IPTV client to play content associated therewith. If desired, the proxy server can request of the content server a list of options, and the list is returned to the proxy server. Asset information may be requested by the IPTV client and returned thereto by the content server. Also, a service login received from the control device may be sent by the IPTV client to the content server and a service token returned to the IPTV client in response.
- In another aspect, a consumer electronic (CE) control device includes a housing holding a display, a network interface, and a processor controlling the display and communicating with the Internet through the network interface. An input device communicates with the processor. The processor executing logic including sending login information to a proxy server, and receiving from the proxy server, responsive to reception thereby of correct login information, a local IP address of an IPTV client. The processor uses the local IPTV address to access the IPTV client directly to request information about the IPTV client, sending the information about the IPTV client to the proxy server. Responsive to sending the information about the IPTV client to the proxy server, the processor receives content information, presenting it on the display from which a user can select a selected content. The processor commands the IPTV client to play the selected content.
- In another aspect, a proxy server assembly includes at least one processor and at least one network interface communicating with the processor to establish communication between the processor and a wide area network. At least one computer readable storage medium is accessible to the processor and bears logic causing the processor to receive login information from a control device. Responsive to a determination that the login information is correct, the server sends to the control device a local IP address of an IPTV client associated with the login information. The server receives from the control device information about the IPTV client requesting a list of services available to the IPTV client from at least one content server and sends a request for the list of services to a management server. The proxy server receives from the management server the list and sends it to the control device for presentation of information on a video display thereof. The proxy server then receives from the control device a request for a software asset and responsive to the request for the software asset, requests a service login of the content server. The proxy server receives back from the content server a list of assets or categories or services and sends the list to the control device. In this way, the list can be presented on a video display of the control device so that a user can navigate to enter a selection to command the IPTV client to play the selection.

FIG. 1 , anetwork interface 28 such as a wired or wireless modem or wireless telephony transceiver communicates with theprocessor 16 to provide connectivity to a wide area network such as the Internet. Double arrows inFIG. 1 indicate network communication between components over wired and/or wireless links. In this way, theclient device 12 can communicate with amanagement server 30 on the Internet and with one ormore content servers 32, also on the Internet and communicating with themanagement server 30. If desired, eachcontent server 32 may be associated with arespective proxy server 34 which interfaces thecontent server 32 with thedevice 12. Theservers respective processors readable storage media CE device 12 particularly when implemented by a non-PC device such as a TV or game console or camera can communicate only with themanagement server 30 and withcontent servers 32 that appear on a service list provided to theprocessor 16 by themanagement server 30, with the service list not being modifiable by theprocessor 16. - A second or
control CE device 36 withhousing 38 such as another TV, game player, video disk player, camera, digital clock radio, mobile telephone, personal digital assistant, laptop computer, etc. bears adigital processor 40 controlling avisual display 42 and anaudible display 44 such as one or more speakers. To undertake present principles, the second orcontrol processor 40 may access one or more computerreadable storage media 46 such as but not limited to RAM-based storage (e.g., a chip implementing dynamic random access memory (DRAM)) or flash memory or disk-based-storage. Software code implementing present logic executable by the second orcontrol device 36 may also be stored on one of the memories shown to undertake present principles. Further, the second orcontrol processor 40 can receive user input signals fromvarious input devices 48 including a point and click device such as a mouse, a keypad, etc. Anetwork interface 50 such as a wired or wireless modem or wireless telephony transceiver communicates with theprocessor 40 to provide connectivity to a wide area network such as the Internet. -
FIG. 2 shows an example embodiment of present principles for enabling a user to use asecond device 36 to browse assets and select one to have amain IPTV 12 client play the content.FIG. 2 assumes that the user has already created an account with themanagement server 30 and has affiliated the main IPTV device with that account. - At state 52 a user turns on the
primary device 12, hereafter referred to as the “IPTV client” for convenience. Atstate 54 the IPTV client sends login information including, e.g., user name and password to themanagement server 30, which at state 56 returns to the IPTV client a user token that must subsequently be presented by the IPTV client to a participatingcontent server 32 to obtain content from that server. Also, themanagement server 30 stores the local IP address of theIPTV client 12. - At
state 58, the user instantiates an IPTV client control utility on thesecond device 36, referred to hereafter for convenience as the control device. The utility executed on thecontrol device 36, atstate 60, sends a GET request to theproxy server 34, which returns (62) hypertext markup language (HTML) with JavaScript for thecontrol device 36 to execute in accordance with description below. This Javascript makes asynchronous Javascript and extended markup language (XML) (AJAX) calls to the proxy server and to the IPTV client to obtain information to control the IPTV client. - With more specificity, at
state 64 using the Javascript received from theproxy server 34 thecontrol device 36 prompts the user to input to thecontrol device 36 the account login information, including, e.g., the same user name and password that the IPTV client provided to themanagement server 30 at 54. It will thus be appreciated that theservers - At state 66 the
proxy server 34, responsive to a correct user name and password from thecontrol device 36, returns information about allIPTV clients 12 that are affiliated with the user account associated with the user name and password, including their local IP addresses which were stored by themanagement server 30 after login at 54 (and subsequently provided to the proxy server 34). - When the user inputs to the
control device 36 at state 68 a selected IPTV client (in this example, the IPTV client 12) to use with the control device, thecontrol device 36, using the local IP address returned at state 66, accesses theIPTV client 12 directly. Thecontrol device 36 requests information about theIPTV client 12 atstate 70, including language information, rating information, digital rights management (DRM) information, etc. as desired, which information is returned from theIPTV client 12 to thecontrol device 36 atstate 72. Since thecontrol device 36 knows the IP address of theIPTV client 12 and consequently communicates directly with theIPTV client 12, thecontrol device 36 communicates using a local web address of theIPTV client 12 that need not be globally addressable, and may so communicate as long as thecontrol device 36 andIPTV client 12 are on the same local network. - At
state 74 thecontrol device 36 sends the client information received atstate 72 to theproxy server 34, requesting a list of services available to theIPTV client 12 from one or more of thecontent servers 32. Theproxy server 34 relays the request atstate 76 to themanagement server 30, which returns the requested service list atstate 78 to theproxy server 34. Theproxy server 34 in turn sends the services list to thecontrol device 36 at state 80 for presentation of available services on, e.g., thecontrol device display 42. -
State 82 indicates that a user can input (using, e.g., the control device input device 48) a selection of a service on the list that was returned to the control device at state 80. In response, thecontrol device 36, atstate 84, sends a request for the corresponding software asset to theproxy server 34 along with a service token that the control device may have received from thecontent server 32 via themanagement server 30. - Responsive to the request, at
state 86 the proxy server requests a service login atstate 86 of thecontent server 32 providing the selected service. Atstate 88 thecontent server 32 provides to the proxy server 34 a list of assets or categories or services, as the case may be for theparticular content server 34.State 90 indicates that if desired theproxy server 34 may also request of thecontent server 32 a list of options, and the list is returned atstate 92 in, e.g., extended markup language (XML) format to theproxy server 34, which relays the assets, categories, services, etc. available for selection to thecontrol device 36 atstate 94. - The content available for selection is presented on the
control device display 42 so that the user can navigate (96) the display to enter (98) a selection. Responsive to the selection thecontrol device 36 atstate 98 sends a command to theIPTV client 12 to play the selection. Atstate 100 theIPTV client 12 then requests of themanagement server 30 information about the service the selected asset is in, logging in to the service if required. The requested information is returned from themanagement server 30 to theIPTV client 12 at state 102, and when theIPTV client 12 receives the asset information it plays the asset at state 116. Note that if the IPTV client is already playing content the new content commanded to be played by the control device is placed in a queue in the IPTV client and played when the current content completes. - Note further that the control device may command the IPTV client to play content by sending to the IPTV client over the home network commands coded as if they were sent from an infrared remote control (IR RC), specifically for example the commands may be in Sony Infrared Remote Control System (SIRCS) protocol.
- As shown in
FIG. 2 , if desired, temporally between states 102 and 116 a series of messages may be exchanged between theIPTV client 12 and thecontent server 32. For example, asset information may be requested (104) by theIPTV client 12 and returned (106) by thecontent server 32. The above-described service login may be relayed by theIPTV client 12 to thecontent server 32 atstate 108 and a service token returned to the IPTV client atstate 110 along with the before-mentioned asset information. Also, a playlist may be requested by (112) and returned to (114) theIPTV client 12. - The Javascript/HTML software that is downloaded at
state 62 can be make available to all electronic vendors who wish their users to be able to navigate, browse, and search IPTV content on a second device. - While the particular CONTROL OF IPTV USING SECOND DEVICE is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
