Moreover, the first set-top box device 116 can communicate with a first remote control 120, and the second set-top box device can communicate with a second remote control 128. In an exemplary, non-limiting embodiment, each set-top box device 116 and 124 can receive data or video from the client-facing tier 102 via the private access network 166 and render or display the data or video at the display device 118 or 126 to which it is coupled. The set-top box devices 116 and 124 thus may include tuners that receive and decode television programming information for transmission to the display devices 118 and 126. Further, the set-top box devices 116 and 124 can include an STB processor 170 and an STB memory device 172 that is accessible to the STB processor. In a particular embodiment, the set-top box devices 116 and 124 can also communicate commands received from the remote controls 120 and 128 back to the client-facing tier 102 via the private access network 166.
In an illustrative embodiment, the client-facing tier 102 can include a client-facing tier (CFT) switch 130 that manages communication between the client-facing tier 102 and the private access network 166 and between the client-facing tier 102 and the private network 110. As shown, the CFT switch 130 is coupled to one or more data servers 132 that store data transmitted in response to user requests, such as video-on-demand material. The CFT switch 130 can also be coupled to a terminal server 134 that provides terminal devices, such as a game application server and other devices with a common connection point to the private network 110. In a particular embodiment, the CFT switch 130 can also be coupled to a video-on-demand (VOD) server 136.
The application tier 104 can communicate with both the private network 110 and the public network 112. In this embodiment, the application tier 104 can include a first application tier (APP) switch 138 and a second APP switch 140. In a particular embodiment, the first APP switch 138 can be coupled to the second APP switch 140. The first APP switch 138 can be coupled to an application server 142 and to an OSS/BSS gateway 144. The application server 142 provides applications to the set-top box devices 116 and 124 via the private access network 166, so the set-top box devices 116 and 124 can provide functions such as display, messaging, processing of IPTV data and VOD material. In a particular embodiment, the OSS/BSS gateway 144 includes operation systems and support (OSS) data, as well as billing systems and support (BSS) data.

The second APP switch 140 can be coupled to a subscriber and system store 148 that includes account information, such as account information that is associated with users who access the system 100 via the private network 110 or the public network 112. In a particular embodiment, the application tier 104 can also include a client gateway 150 that communicates data directly to the client-facing tier 102. In this embodiment, the client gateway 150 can be coupled directly to the CFT switch 130. The client gateway 150 can provide user access to the private network 110 and the tiers coupled thereto.
In a particular embodiment, the set-top box devices 116 and 124 can access the system via the private access network 166 using information received from the client gateway 150. The private access network 166 provides security for the private network 110. User devices can access the client gateway 150 via the private access network 166, and the client gateway 150 can allow such devices to access the private network 110 once the devices are authenticated or verified. Similarly, the client gateway 150 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices from accessing the private network 110, by denying access to these devices beyond the private access network 166.
For example, when the set-top box device 116 accesses the system 100 via the private access network 166, the client gateway 150 can verify subscriber information by communicating with the subscriber and system store 148 via the private network 110, the first APP switch 138 and the second APP switch 140. Further, the client gateway 150 can verify billing information and status by communicating with the OSS/BSS gateway 144 via the private network 110 and the first APP switch 138. The OSS/BSS gateway 144 can transmit a query across the first APP switch 138, to the second APP switch 140, and the second APP switch 140 can communicate the query across the public network 112 to the OSS/BSS server 164. After the client gateway 150 confirms subscriber and/or billing information, the client gateway 150 can allow the set-top box device 116 access to IPTV content and VOD content. If the client gateway 150 cannot verify subscriber information for the set-top box device 116, such as because it is connected to a different twisted pair, the client gateway 150 can deny transmissions to and from the set-top box device 116 beyond the private access network 166.
The acquisition tier 106 includes an acquisition tier (AQT) switch 152 that communicates with the private network 110. The AQT switch 152 can also communicate with the operations and management tier 108 via the public network 112. In a particular embodiment, the AQT switch 152 can be coupled to a live acquisition server 154 that receives television content, for example, from a broadcast service 156. Further, the AQT switch can be coupled to a video-on-demand importer server 158 that stores television content received at the acquisition tier 106 and communicate the stored content to the client-facing tier 102 via the private network 110.
The operations and management tier 108 can include an operations and management tier (OMT) switch 160 that conducts communication between the operations and management tier 108 and the public network 112. In the illustrated embodiment, the OMT switch 160 is coupled to a TV2 server 162. Additionally, the OMT switch 160 can be coupled to an OSS/BSS server 164 and to a simple network management protocol (SNMP) monitor 166 that monitors network devices. In a particular embodiment, the OMT switch 160 can communicate with the AQT switch 152 via the public network 112.
In a particular embodiment during operation of the IPTV system, the live acquisition server 154 can acquire television content from the broadcast service 156. The live acquisition server 154 in turn can transmit the television content to the AQT switch 152 and the AQT switch can transmit the television content to the CFT switch 130 via the private network 110. Further, the television content can be encoded at the D-servers 132, and the CFT switch 130 can communicate the television content to the modems 114 and 122 via the private access network 166. The set-top box devices 116 and 124 can receive the television content from the modems 114 and 122, decode the television content, and transmit the content to the display devices 118 and 126 according to commands from the remote control devices 120 and 128.
Additionally, at the acquisition tier 106, the video-on-demand (VOD) importer server 158 can receive content from one or more VOD sources outside the IPTV system 100, such as movie studios and programmers of non-live content. The VOD importer server 158 can transmit the VOD content to the AQT switch 152, and the AQT switch 152 in turn can communicate the material to the CFT switch 130 via the private network 110. The VOD content can be stored at one or more servers, such as the VOD server 136.
When a user issues a request for VOD content to the set-top box device 116 or 124, the request can be transmitted over the private access network 166 to the VOD server 136 via the CFT switch 130. Upon receiving such a request, the VOD server 136 can retrieve requested VOD content and transmit the content to the set-top box device 116 or 124 across the private access network 166 via the CFT switch 130. In an illustrative embodiment, the live acquisition server 154 can transmit the television content to the AQT switch 152, and the AQT switch 152 in turn can transmit the television content to the OMT switch 160 via the public network 112. In this embodiment, the OMT switch 160 can transmit the television content to the TV2 server 162 for display to users accessing the user interface at the TV2 server. For example, a user can access the TV2 server 162 using a personal computer 168 coupled to the public network 112.
The domain controller 146 communicates with the public network 112 via the second APP switch 140. Additionally, the domain controller 146 can communicate via the public network 112 with the personal computer 168. For example, the domain controller 146 can display a web portal via the public network 112 and allow users to access the web portal using the PC 168. Further, in an illustrative embodiment, the domain controller 146 can communicate with at least one wireless network access point 178 over a data network 176. In this embodiment, each wireless network access device 178 can communicate with user wireless devices such as a cellular telephone 180.
In a particular embodiment, the set-top box devices can include an STB computer program 174 that is embedded within the STB memory device 172. The STB computer program 174 can contain instructions to receive and execute at least one user television viewing preference that a user has entered by accessing an Internet user account via the domain controller 146. For example, the user can use the PC 168 to access a web portal maintained by the domain controller 146 via the Internet. The domain controller 146 can query the subscriber and system store 148 via the private network 110 for account information associated with the user. In a particular embodiment, the account information can associate the user's Internet account with the second set-top box device 124. For instance, in an illustrative embodiment, the account information can relate the user's account to the second set-top box device 124 by associating the user account with an IP address of the second set-top box device, with data relating to one or more twisted pairs connected with the second set-top box device, with data related to one or more fiber optic cables connected with the second set-top box device, with an alphanumeric identifier of the second set-top box device, with any other data that is suitable for associating second set-top box device with a user account, or with any combination of these.

FIG. 5 shows a method of troubleshooting a set top box from a repair center is shown and commences at block 500. At block 500, when a trouble ticket is received at a repair center, a do loop is entered and the following steps are performed. At blocks 502 and 504, a self test at the set top box can be initiated. For example, at block 502, a self test command can be sent to the set top box via an out of band interface. Alternatively, at block 504, the user can be instructed to initiate a self test of the set top box via a predetermined key sequence on a remote control device.
Moving to block 506, the test results from the set top box can be received at the repair center. At block 508, the test results can be analyzed. Further at decision step 510, it can be determined whether the problem with the set top box is isolated. If not, the method can return to block 502/504 and continue as described herein. If the problem at the set top box is isolated, the method can move to block 512 and the problem can be repair. At block 514, the repair center can indicate to the user that the problem has been fixed. Further, at block 516, the trouble ticket can be closed. The method can then end at state 518.
FIG. 6 illustrates a method of troubleshooting a set top box at the set top box. Beginning at block 600, when a self test is initiated, the set top box can perform a series of self tests. For example, at block 602, the set top box can perform an IP-layer connectivity test. The IP-layer connectivity test can be a trace route, or ping, test that can be used to test the network connectivity. At block 604, the set top box can perform a physical layer connectivity test.

This test can include testing analyzing video delivery and decoding at the set top box. Further, this test can include analyzing received video packets, video frame performance (e.g., I-frame loss), video decoding buffer over-flow/under-flow, MPEG2 PCR jitter, latency, packet delivery rate, discontinuity, etc.
Proceeding to decision step 612, the set top box can determine whether any of the series of self tests has failed to complete. If none of the tests fail, the method can move to block 614 and the full test results can be transmitted to the repair center, or some other remote location. The test results can be transmitted to the repair center through an in-band interface or an out of band interface. For example, if video service channel has network connection issues, the set top box can upload, or report, performance data through secondary wireless channels, e.g., Wimax, WiFi, etc. At block 616, the set top box can display the test results at a display device coupled to the set top box. A customer service representative, or technician, can use the test results in an attempt to fix, or repair, the problem.
Moving to block 618, the set top box can perform a root cause analysis in order to isolate the problem. At decision step 620, the set top box can determine whether the problem is isolated. If so, the method can proceed to block 622 and the set top box can indicate to the user and to the repair center that the problem has been isolated. The method can then end at state 624.
Returning to decision step 620, if the problem is not isolated, the method can move to block 626 and the set top box can indicate to the user and the repair center that further analysis is required. The method can then end at state 624.
Returning now to decision step 612, if any test fails to complete, the method can move to block 628 and the set top box can transmit a failed test message to the repair center. Thereafter, at decision step 630, it can be determined whether to retry the failed test. This determination can be based on a request from the repair center, i.e., the repair center can request that the set top box repeat the failed test. If the set top box determines to repeat the failed test, the method can return to blocks 602 through 610 and repeat the failed test, or tests. Conversely, if the set top box determines not to repeat the failed test, the method can move to block 632 and the set top box can transmit the partial test results to the repair center. Thereafter, the set top box can indicate to the user that further testing is required. The method can then at state 624.
