FIG. 1 depicts an illustrative embodiment of a first communication system 100 for delivering media content. The communication system 100 can represent an Internet Protocol Television (IPTV) broadcast media system. In a typical IPTV infrastructure, there is a super head-end office (SHO) with at least one super headend office server (SHS) which receives national media programs from satellite and/or media servers from service providers of multimedia broadcast channels. In the present context, media programs can represent audio content, moving image content such as videos, still image content, and/or combinations thereof. The SHS server forwards IP packets associated with the media content to video head-end servers (VHS) via a network of aggregation points such as video head-end offices (VHO) according to a common multicast communication method.
The VHS then distributes multimedia broadcast programs via a local area network (LAN) to commercial and/or residential buildings 102 housing a gateway 104 (e.g., a residential gateway or RG). The LAN can represent a bank of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over optical links or copper twisted pairs to buildings 102. The gateway 104 distributes broadcast signals to media processors 106 such as Set-Top Boxes (STBs) which in turn present broadcast selections to media devices 108 such as computers or television sets managed in some instances by a media controller 107 (e.g., an infrared or RF remote control). Unicast traffic can also be exchanged between the media processors 106 and subsystems of the IPTV media system for services such as video-on-demand (VoD). It will be appreciated by one of ordinary skill in the art that the media devices 108 and/or portable communication devices 116 shown in FIG. 1 can be an integral part of the media processor 106 and can be communicatively coupled to the gateway 104. In this particular embodiment, an integral device such as described can receive, respond, process and present multicast or unicast media content.
The IPTV media system can be coupled to one or more computing devices 130 a portion of which can operate as a web server for providing portal services over an Internet Service Provider (ISP) network 132 to fixed line media devices 108 or portable communication devices 116 by way of a wireless access point 117 providing Wireless Fidelity or WiFi services, or cellular communication services (e.g., GSM, CDMA, UMTS, WiMAX, etc.). A satellite broadcast television system can be used in place of the IPTV media system. In this embodiment, signals transmitted by a satellite 115 can be intercepted by a satellite dish receiver 131 coupled to building 102 which conveys media signals to the media processors 106. The media receivers 106 can be equipped with a broadband port to the ISP network 132. Although not shown, the communication system 100 can also be combined or replaced with analog or digital broadcast distributions systems such as cable TV systems.
FIG. 2 depicts an illustrative embodiment of a second communication system 200 for delivering media content. Communication system 200 can be overlaid or operably coupled with communication system 100 as another representative embodiment of said communication system. The system 200 includes a distribution switch/router system 228 at a central office 218. The distribution switch/router system 228 receives video data via a multicast television stream 230 from a second distribution switch/router 234 at an intermediate office 220. The multicast television stream 230 includes Internet Protocol (IP) data packets addressed to a multicast IP address associated with a television channel. The distribution switch/router system 228 can cache data associated with each television channel received from the intermediate office 220.
The distribution switch/router system 228 also receives unicast data traffic from the intermediate office 220 via a unicast traffic stream 232. The unicast traffic stream 232 includes data packets related to devices located at a particular residence, such as the residence 202. For example, the unicast traffic stream 232 can include data traffic related to a digital subscriber line, a telephone line, another data connection, or any combination thereof. To illustrate, the unicast traffic stream 232 can communicate data packets to and from a telephone 212 associated with a subscriber at the residence 202. The telephone 212 can be a Voice over Internet Protocol (VoIP) telephone. To further illustrate, the unicast traffic stream 232 can communicate data packets to and from a personal computer 210 at the residence 202 via one or more data routers 208. In an additional illustration, the unicast traffic stream 232 can communicate data packets to and from a set-top box device, such as the set-top box devices 204, 206. The unicast traffic stream 232 can communicate data packets to and from the devices located at the residence 202 via one or more residential gateways 214 associated with the residence 202.
The distribution switch/router system 228 can send data to one or more access switch/router systems 226. The access switch/router system 226 can include or be included within a service area interface 216. In a particular embodiment, the access switch/router system 226 can include a DSLAM. The access switch/router system 226 can receive data from the distribution switch/router system 228 via a broadcast television (BTV) stream 222 and a plurality of unicast subscriber traffic streams 224. The BTV stream 222 can be used to communicate video data packets associated with a multicast stream.
For example, the BTV stream 222 can include a multicast virtual local area network (VLAN) connection between the distribution switch/router system 228 and the access switch/router system 226. Each of the plurality of subscriber traffic streams 224 can be used to communicate subscriber specific data packets. For example, the first subscriber traffic stream can communicate data related to a first subscriber, and the nth subscriber traffic stream can communicate data related to an nth subscriber. Each subscriber to the system 200 can be associated with a respective subscriber traffic stream 224. The subscriber traffic stream 224 can include a subscriber VLAN connection between the distribution switch/router system 228 and the access switch/router system 226 that is associated with a particular set-top box device 204, 206, a particular residence 202, a particular residential gateway 214, another device associated with a subscriber, or any combination thereof.
In an illustrative embodiment, a set-top box device, such as the set-top box device 204, receives a channel change command from an input device, such as a remoter control device. The channel change command can indicate selection of an IPTV channel. After receiving the channel change command, the set-top box device 204 generates channel selection data that indicates the selection of the IPTV channel. The set-top box device 204 can send the channel selection data to the access switch/router system 226 via the residential gateway 214. The channel selection data can include an Internet Group Management Protocol (IGMP) Join request. In an illustrative embodiment, the access switch/router system 226 can identify whether it is joined to a multicast group associated with the requested channel based on information in the IGMP Join request.
If the access switch/router system 226 is not joined to the multicast group associated with the requested channel, the access switch/router system 226 can generate a multicast stream request. The multicast stream request can be generated by modifying the received channel selection data. In an illustrative embodiment, the access switch/router system 226 can modify an IGMP Join request to produce a proxy IGMP Join request. The access switch/router system 226 can send the multicast stream request to the distribution switch/router system 228 via the BTV stream 222. In response to receiving the multicast stream request, the distribution switch/router system 228 can send a stream associated with the requested channel to the access switch/router system 226 via the BTV stream 222.

The client-facing tier 302 can communicate with user equipment via an access network 366, such as an IPTV access network. In an illustrative embodiment, customer premises equipment (CPE) 314, 322 can be coupled to a local switch, router, or other device of the access network 366. The client-facing tier 302 can communicate with a first representative set-top box device 316 via the first CPE 314 and with a second representative set-top box device 324 via the second CPE 322. In a particular embodiment, the first representative set-top box device 316 and the first CPE 314 can be located at a first customer premise, and the second representative set-top box device 324 and the second CPE 322 can be located at a second customer premise.
In another particular embodiment, the first representative set-top box device 316 and the second representative set-top box device 324 can be located at a single customer premise, both coupled to one of the CPE 314, 322. The CPE 314, 322 can include routers, local area network devices, modems, such as digital subscriber line (DSL) modems, any other suitable devices for facilitating communication between a set-top box device and the access network 366, or any combination thereof.
In an illustrative embodiment, the client-facing tier 302 can be coupled to the CPE 314, 322 via fiber optic cables. In another illustrative embodiment, the CPE 314, 322 can include DSL modems that are coupled to one or more network nodes via twisted pairs, and the client-facing tier 302 can be coupled to the network nodes via fiber-optic cables. Each set-top box device 316, 324 can process data received via the access network 366, via a common IPTV software platform.
The first set-top box device 316 can be coupled to a first external display device, such as a first television monitor 318, and the second set-top box device 324 can be coupled to a second external display device, such as a second television monitor 326. Moreover, the first set-top box device 316 can communicate with a first remote control 320, and the second set-top box device 324 can communicate with a second remote control 328. The set-top box devices 316, 324 can include IPTV set-top box devices; video gaming devices or consoles that are adapted to receive IPTV content; personal computers or other computing devices that are adapted to emulate set-top box device functionalities; any other device adapted to receive IPTV content and transmit data to an IPTV system via an access network; or any combination thereof.
In an illustrative, non-limiting embodiment, each set-top box device 316, 324 can receive data, video, or any combination thereof, from the client-facing tier 302 via the access network 366 and render or display the data, video, or any combination thereof, at the display device 318, 326 to which it is coupled.

Further, the set-top box devices 316, 324 can each include a STB processor 370 and a STB memory device 372 that is accessible to the STB processor 370. In one embodiment, a computer program, such as the STB computer program 374, can be embedded within the STB memory device 372.
In an illustrative embodiment, the client-facing tier 302 can include a client-facing tier (CFT) switch 330 that manages communication between the client-facing tier 302 and the access network 366 and between the client-facing tier 302 and the private network 310. As illustrated, the CFT switch 330 is coupled to one or more distribution servers, such as Distribution-servers (D-servers) 332, that store, format, encode, replicate, or otherwise manipulate or prepare video content for communication from the client-facing tier 302 to the set-top box devices 316, 324. The CFT switch 330 can also be coupled to a terminal server 334 that provides terminal devices with a point of connection to the IPTV system 300 via the client-facing tier 302.
In a particular embodiment, the CFT switch 330 can be coupled to a VoD server 336 that stores or provides VoD content imported by the IPTV system 300. Further, the CFT switch 330 is coupled to one or more video servers 380 that receive video content and transmit the content to the set-top boxes 316, 324 via the access network 366. The client-facing tier 302 may include a CPE management server 382 that manages communications to and from the CPE 314 and the CPE 322. For example, the CPE management server 382 may collect performance data associated with the set-top box devices 316, 324 from the CPE 314 or the CPE 322 and forward the collected performance data to a server associated with the operations and management tier 308.
In an illustrative embodiment, the client-facing tier 302 can communicate with a large number of set-top boxes, such as the representative set-top boxes 316, 324, over a wide geographic area, such as a metropolitan area, a viewing area, a statewide area, a regional area, a nationwide area or any other suitable geographic area, market area, or subscriber or customer group that can be supported by networking the client-facing tier 302 to numerous set-top box devices. In a particular embodiment, the CFT switch 330, or any portion thereof, can include a multicast router or switch that communicates with multiple set-top box devices via a multicast-enabled network.
As illustrated in FIG. 3, the application tier 304 can communicate with both the private network 310 and the public network 312. The application tier 304 can include a first application tier (APP) switch 338 and a second APP switch 340. In a particular embodiment, the first APP switch 338 can be coupled to the second APP switch 340. The first APP switch 338 can be coupled to an application server 342 and to an OSS/BSS gateway 344. In a particular embodiment, the application server 342 can provide applications to the set-top box devices 316, 324 via the access network 366, which enable the set-top box devices 316, 324 to provide functions, such as interactive program guides, video gaming, display, messaging, processing of VoD material and other IPTV content, etc. In an illustrative embodiment, the application server 342 can provide location information to the set-top box devices 316, 324. In a particular embodiment, the OSS/BSS gateway 344 includes operation systems and support (OSS) data, as well as billing systems and support (BSS) data. In one embodiment, the OSS/BSS gateway 344 can provide or restrict access to an OSS/BSS server 364 that stores operations and billing systems data.
The second APP switch 340 can be coupled to a domain controller 346 that provides Internet access, for example, to users at their computers 368 via the public network 312. For example, the domain controller 346 can provide remote Internet access to IPTV account information, e-mail, personalized Internet services, or other online services via the public network 312. In addition, the second APP switch 340 can be coupled to a subscriber and system store 348 that includes account information, such as account information that is associated with users who access the IPTV system 300 via the private network 310 or the public network 312. In an illustrative embodiment, the subscriber and system store 348 can store subscriber or customer data and create subscriber or customer profiles that are associated with IP addresses, stock-keeping unit (SKU) numbers, other identifiers, or any combination thereof, of corresponding set-top box devices 316, 324. In another illustrative embodiment, the subscriber and system store can store data associated with capabilities of set-top box devices associated with particular customers.
In a particular embodiment, the application tier 304 can include a client gateway 350 that communicates data directly to the client-facing tier 302. In this embodiment, the client gateway 350 can be coupled directly to the CFT switch 330. The client gateway 350 can provide user access to the private network 310 and the tiers coupled thereto. In an illustrative embodiment, the set-top box devices 316, 324 can access the IPTV system 300 via the access network 366, using information received from the client gateway 350. User devices can access the client gateway 350 via the access network 366, and the client gateway 350 can allow such devices to access the private network 310 once the devices are authenticated or verified. Similarly, the client gateway 350 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices from accessing the private network 310, by denying access to these devices beyond the access network 366.
For example, when the first representative set-top box device 316 accesses the client-facing tier 302 via the access network 366, the client gateway 350 can verify subscriber information by communicating with the subscriber and system store 348 via the private network 310. Further, the client gateway 350 can verify billing information and status by communicating with the OSS/BSS gateway 344 via the private network 310. In one embodiment, the OSS/BSS gateway 344 can transmit a query via the public network 312 to the OSS/BSS server 364. After the client gateway 350 confirms subscriber and/or billing information, the client gateway 350 can allow the set-top box device 316 to access IPTV content and VoD content at the client-facing tier 302. If the client gateway 350 cannot verify subscriber information for the set-top box device 316, e.g., because it is connected to an unauthorized twisted pair, the client gateway 350 can block transmissions to and from the set-top box device 316 beyond the access network 366.
As indicated in FIG. 3, the acquisition tier 306 includes an acquisition tier (AQT) switch 352 that communicates with the private network 310. The AQT switch 352 can also communicate with the operations and management tier 308 via the public network 312. In a particular embodiment, the AQT switch 352 can be coupled to one or more live Acquisition-servers (A-servers) 354 that receive or acquire television content, movie content, advertisement content, other video content, or any combination thereof, from a broadcast service 356, such as a satellite acquisition system or satellite head-end office. In a particular embodiment, the live acquisition server 354 can transmit content to the AQT switch 352, and the AQT switch 352 can transmit the content to the CFT switch 330 via the private network 310.
In an illustrative embodiment, content can be transmitted to the D-servers 332, where it can be encoded, formatted, stored, replicated, or otherwise manipulated and prepared for communication from the video server(s) 380 to the set-top box devices 316, 324. The CFT switch 330 can receive content from the video server(s) 380 and communicate the content to the CPE 314, 322 via the access network 366. The set-top box devices 316, 324 can receive the content via the CPE 314, 322, and can transmit the content to the television monitors 318, 326. In an illustrative embodiment, video or audio portions of the content can be streamed to the set-top box devices 316, 324.
Further, the AQT switch 352 can be coupled to a video-on-demand importer server 358 that receives and stores television or movie content received at the acquisition tier 306 and communicates the stored content to the VoD server 336 at the client-facing tier 302 via the private network 310. Additionally, at the acquisition tier 306, the VoD importer server 358 can receive content from one or more VoD sources outside the IPTV system 300, such as movie studios and programmers of non-live content. The VoD importer server 358 can transmit the VoD content to the AQT switch 352, and the AQT switch 352, in turn, can communicate the material to the CFT switch 330 via the private network 310. The VoD content can be stored at one or more servers, such as the VoD server 336.
When users issue requests for VoD content via the set-top box devices 316, 324, the requests can be transmitted over the access network 366 to the VoD server 336, via the CFT switch 330. Upon receiving such requests, the VoD server 336 can retrieve the requested VoD content and transmit the content to the set-top box devices 316, 324 across the access network 366, via the CFT switch 330. The set-top box devices 316, 324 can transmit the VoD content to the television monitors 318, 326. In an illustrative embodiment, video or audio portions of VoD content can be streamed to the set-top box devices 316, 324.
FIG. 3 further illustrates that the operations and management tier 308 can include an operations and management tier (OMT) switch 360 that conducts communication between the operations and management tier 308 and the public network 312. In the embodiment illustrated by FIG. 3, the OMT switch 360 is coupled to a TV2 server 362. Additionally, the OMT switch 360 can be coupled to an OSS/BSS server 364 and to a simple network management protocol monitor 386 that monitors network devices within or coupled to the IPTV system 300. In a particular embodiment, the OMT switch 360 can communicate with the AQT switch 352 via the public network 312.
The OSS/BSS server 364 may include a cluster of servers, such as one or more CPE data collection servers that are adapted to request and store operations systems data, such as performance data from the set-top box devices 316, 324. In an illustrative embodiment, the CPE data collection servers may be adapted to analyze performance data to identify a condition of a physical component of a network path associated with a set-top box device, to predict a condition of a physical component of a network path associated with a set-top box device, or any combination thereof.
In an illustrative embodiment, the live acquisition server 354 can transmit content to the AQT switch 352, and the AQT switch 352, in turn, can transmit the content to the OMT switch 360 via the public network 312. In this embodiment, the OMT switch 360 can transmit the content to the TV2 server 362 for display to users accessing the user interface at the TV2 server 362. For example, a user can access the TV2 server 362 using a personal computer 368 coupled to the public network 312.
It should be apparent to one of ordinary skill in the art from the foregoing media communication system embodiments that other suitable media communication systems for distributing broadcast media content as well as peer-to-peer exchange of content can be applied to the present disclosure.
FIG. 4 depicts an illustrative embodiment of a communication system 400 employing an IP Multimedia Subsystem (IMS) network architecture. Communication system 400 can be overlaid or operably coupled with communication systems 100-300 as another representative embodiment of said communication systems.
The communication system 400 can comprise a Home Subscriber Server (HSS) 440, a tElephone NUmber Mapping (ENUM) server 430, and network elements of an IMS network 450. The IMS network 450 can be coupled to IMS compliant communication devices (CD) 401, 402 or a Public Switched Telephone Network (PSTN) CD 403 using a Media Gateway Control Function (MGCF) 420 that connects the call through a common PSTN network 460.
IMS CDs 401, 402 register with the IMS network 450 by contacting a Proxy Call Session Control Function (P-CSCF) which communicates with a corresponding Serving CSCF (S-CSCF) to register the CDs with an Authentication, Authorization and Accounting (AAA) supported by the HSS 440. To accomplish a communication session between CDs, an originating IMS CD 401 can submit a Session Initiation Protocol (SIP INVITE) message to an originating P-CSCF 404 which communicates with a corresponding originating S-CSCF 406. The originating S-CSCF 406 can submit the SIP INVITE message to an application server (AS) such as reference 410 that can provide a variety of services to IMS subscribers. For example, the application server 410 can be used to perform originating treatment functions on the calling party number received by the originating S-CSCF 406 in the SIP INVITE message.
Originating treatment functions can include determining whether the calling party number has international calling services, and/or is requesting special telephony features (e.g., *72 forward calls, *73 cancel call forwarding, *67 for caller ID blocking, and so on). Additionally, the originating S-CSCF 406 can submit queries to the ENUM system 430 to translate an E.164 telephone number to a SIP Uniform Resource Identifier (URI) if the targeted communication device is IMS compliant. If the targeted communication device is a PSTN device, the ENUM system 430 will respond with an unsuccessful address resolution and the S-CSCF 406 will forward the call to the MGCF 420 via a Breakout Gateway Control Function (BGCF) 419.
When the ENUM server 430 returns a SIP URI, the SIP URI is used by an Interrogating CSCF (I-CSCF) 407 to submit a query to the HSS 440 to identify a terminating S-CSCF 414 associated with a terminating IMS CD such as reference 402. Once identified, the I-CSCF 407 can submit the SIP INVITE to the terminating S-CSCF 414 which can call on an application server 411 similar to reference 410 to perform the originating treatment telephony functions described earlier. The terminating S-CSCF 414 can then identify a terminating P-CSCF 416 associated with the terminating CD 402. The P-CSCF 416 then signals the CD 402 to establish communications. The aforementioned process is symmetrical. Accordingly, the terms “originating” and “terminating” in FIG. 4 can be interchanged.
FIG. 5 depicts an illustrative embodiment of a portal 530. The portal 530 can be used for managing services of communication systems 100-400. The portal 530 can be accessed by a Uniform Resource Locator (URL) with a common Internet browser such as Microsoft's Internet Explorer using an Internet-capable communication device such as references 108, 116, or 210 of FIGS. 1-2.

FIG. 6 depicts an illustrative embodiment of a communication system 600 having a plurality of STB's 204 in communication with each other. The exemplary embodiment shows three STB's 204, but any number and configuration of STB's can be utilized. Communication system 600 can be overlaid or operably coupled with communication systems 100-400 as another representative embodiment of said communication systems.
STB's 204 are connected to media devices 605, such as televisions, for the presentation of media in an environment 625. The STB's 204 can be communicatively coupled to each other using a hardwire link 610 and/or wireless techniques of communication. The environment 625 can provide an area for audio overlap among the plurality of STB's 204 for a viewer or listener 650. Audio signal 675, 676 and 677 can be emitted by the monitoring devices 605 within the environment 625. One or more of the audio signals 675, 676 and 677 can be provided with a delay (e.g., 2 ms) as compared to one or more of the other audio signals in order to provide a reverberation or echo for the listener 650. In another embodiment, video signals associated with one or more of the audio signals 675, 676 and 677 can also be provided with a time delay. The audio signal delay can be equal to or different from the video signal delay. In another embodiment, one or more of the audio signals 675, 676 and 677 can be provided with a time delay while each of the associated video signals are presented simultaneously.
FIG. 7 depicts an exemplary method 700 operating in portions of one or more of the communication systems 100-400 and 600. Method 700 has variants as depicted by the dashed lines. It would be apparent to an artisan with ordinary skill in the art that other embodiments not depicted in FIG. 7 are possible without departing from the scope of the claims described below. For convenience, reference to one or more features of communication system 600 as used in the following paragraphs can mean one or more features of the communication systems 100, 200, 300, 400 and 600 singly or in combination, including STBs 204, 206, 316 106 and/or 324.
Method 700 can begin with step 702 where the STB 204 can monitor for a request for reverberation. The STB 204 can be one among a plurality of STB's that are communicatively coupled. The request can be made through use of a remote controller in communication with the STB or through other programming options, such as controls on the STB. The request is not limited to a user of the STB 204 and can come from other sources, such as command controls from a back-end server. In one embodiment, the STB 204 can be in a master/slave relationship with the other STB's. In another embodiment, a request for reverberation can be monitored for, and received by, one STB 204 and communicated to another STB.
In step 704, the STB 204 can present a selection of audio or potential time delays to be chosen by a user for one or more of the STB's of the environment 625. The audio delays can be presented in a number of different ways, such as based on time (e.g., between 0.5 and 10 ms delay) or based on description (e.g., stadium or canyon effect). In one embodiment, the time delays can be pre-determined. In another embodiment, the audio delays can be based on a user profile.
In one embodiment, the time delays can be dynamically determined as in step 706. For example, the time delays can be based on the audio characteristics of the particular environment 625, such as the dimensions or configuration of the room, the number of media devices 605, the positioning of the media devices in the environment 625, and so forth. These characteristics can be inputted into the STB 204. In another embodiment, these characteristics can be sensed by the STB 204. The dynamic determination of the time delay can be based on other factors, such as the type of programming.
In step 708, if a delay is not selected then method 700 can return to step 702 to continue monitoring for a request for reverberation. If on the other hand, a selection of a time delay is made then one or more of the STB's 204 can be adjusted according to the selected time delay as in step 710. The adjustment of the STB's 204 can be based on individual time delays chosen for each of the STB's, based on a time delay differential to be applied to each of the STB's, or upon other time delay configurations, such as a staggered echo configuration where the particular time delays are not uniform.
From the foregoing descriptions, it would be evident to an artisan with ordinary skill in the art that the aforementioned embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below. For example, the STB's 204 can be in communication with each other via a wireless technology such as IR, WiMax, WiFi, and so forth. In another embodiment, a single STB 204 can be used for controlling the audio emissions of a plurality of media devices 605. The present disclosure contemplates any configuration of STB's for providing a reverberation through use of time delayed audio signals.
Other suitable modifications can be applied to the present disclosure without departing from the scope of the claims below. Accordingly, the reader is directed to the claims section for a fuller understanding of the breadth and scope of the present disclosure.
