A substantive segment of user devices deployed as part of communication networks can consume digital media in downstream-only modalities, unable to deliver information upstream. While non-interactive consumption of content in such devices generally is satisfactory, interactive consumption of content generally entails upstream delivery of customized information. Consumption of rich digital services (pay-par-view programming, video on demand, digital video recording, etc.) is, therefore, largely unavailable to such devices.
Some embodiments of the disclosure provide indirect in-band control of consumption of content, such as media, in an appliance. The media can comprise data, music, video, advertisement, service notifications, or the like, and the appliance can be customer premises equipment (CPE), such as an electronic device that is part of a network (e.g., a communication network, a home network, a utilities network, or combinations thereof) having various levels of computational capabilities. In certain embodiments, the electronic device can be a display device without computing functionality that renders a previously decoded signal. In networks such as a broadband packet-switched networks, a cable/fiber optic network or a satellite-based network, the available media can comprise linear-programming assets or non-linear assets, such as per-per-view (PPV) assets or video-on-demand (VOD) assets. The indirect in-band control described herein can permit changing a channel in the appliance (e.g., a device such as CPE without upstream functionality) and thus selecting a linear-programming asset, a non-linear asset, etc. Such control can permit regulating consumption of the linear programming asset or the non-linear asset. To implement the disclosed control of consumption of content in an appliance, a device remote from the appliance, and having upstream network connectivity, can leverage data management and control functionality of a service provider network to acquire information related to assets (linear programming, non-linear assets, management assets, such control functions, etc.) made available for consumption by the service provider. Based on the acquired information, the device can transmit an asset request to the service provider network which can process the asset request. In response, the service provider network can transmit content and signaling to the appliance in accordance at least in part with the asset request, thus controlling media consumption in the appliance.
The disclosed indirect control of media consumption can be effected via in-band signaling. Such functionality can include messaging structure specific to indirect control of a remote appliance, network resource assessment, and selection of suitable pathways for delivery of controlled media. In one aspect, the messaging structure of the disclosure can comprise, for example, a broadcast message that, when processed, can cause the appliance to tune to a desired channel (either a linear-programming channel or a media-on-demand channel). In another aspect, the messaging structure of the disclosure can comprise control messages that, when processed, can regulate consumption (selection of content, rendering modality, etc.) of content (e.g., media content) in the appliance. Such control messages can be transmitted to the appliance in-band, in specific channels pathways, rather than broadcast in a service group. Here, a channel pathway can comprise a virtual channel or a downstream frequency carrier in a channel plan (e.g., a predetermined non-empty set of downstream frequencies available to a service group) associated with the appliance.
Some embodiments of the disclosure can provide several advantages. One exemplary advantage can include broadening the scope of digital services accessed through a low-complexity low-cost CPE by exploiting functionality of a device with upstream connectivity to leverage data management and control functionality of the network that is typically accessed through CPE having more complex functionality. Other exemplary advantages include permitting a more fulfilling interactive user experience, and increased quality of service. Affording rich digital services to such equipment can provide additional revenue opportunities for a network operator.

As described in greater detail below, in one aspect, the disclosure relates to indirect control, e.g., via in-band signaling, of consumption of media in an appliance networked in a first network via a device networked in a second network. The first network and the second network can be communication networks that employ wireless or wired communication links, or both. The communication networks can include one or more of wired networks such as coaxial cable, optical fiber, or mixed networks, broadband packet-switched networks, utility networks, or wireless networks such as macrocellular networks (3GPP Long Term Evolution Networks, 4G, etc.), microcellular networks (e.g., Wi-Fi networks, femtocell networks, etc.), satellite-based networks, or any other type of network. The content or media can include linear programming and non-linear assets. The indirect control described herein can permit changing a channel in the appliance (e.g., one-way customer premises equipment) and thus selecting different linear programming, selecting a non-linear asset, and controlling consumption of the non-linear asset. In certain scenarios, the disclosed indirect in-band control can exploit functionality of a device with upstream connectivity to leverage data management and control functionality of a service provider network. Such functionality can include messaging structure specific to indirect control of a remote appliance, network resource assessment, and selection of suitable pathways for delivery of controlled media.
Referring to the drawings,
As illustrated, network A 120 is functionally coupled to a network B 130 via a data and signaling pipe 124. Network B 130 can include wireless networks, wireline networks, and any combination thereof. In one aspect, network B 130 can be administered (e.g., owned, operated, and/or leased) by a network operator that provides services such as digital television content, internet protocol (IP) video content; digital telephony; data services, such as wide-area network services (e.g., internet service) or home network services (e.g., Wi-Fi access, femtocell access) and the like. The data and signaling pipe 124 can comprise one or more of a reference link, and related components; a conventional bus architecture such as address buses, system buses; a conventional wireline link, such as an Ethernet line, a T-carrier line, a twisted-pair line, or the like; a wireless link, including terrestrial wireless links or satellite-based links, or a combination thereof; and so forth.
Network A 120 and network B 130 can include one or more of wide area networks (WANs), one or more local area networks (LANs), signaling networks (e.g., SS#7), etc.), and so forth. Such networks can operate in accordance with any communication protocol, such as protocols for wireline communication or wireless communication. In certain embodiments, network A 120 can have internal structure, with several functional elements that can provide various operational blocks, such as a backbone network (e.g., a high-capacity packet-switched network), a core network platform, a radio access network, etc. Similarly, in such embodiments, network B 130 also can have internal structure, with various functional elements that can provide at least two main operational blocks: a backbone network (e.g., a high-capacity packet-switched network) and a regional access network (RAN). Both the backbone network and the regional access network (RAN) can be WANs, for example, with the backbone network having a larger geographical scope than the RAN. Network A 120 and network B 130 also can include one or more middleware components that, at least partly in conjunction with data and signaling pipe 124, permit functional coupling among such networks, among other functions.
As illustrated, network 130 can be functionally coupled to an appliance 140 via data and signaling pipe which can comprise a downlink 134 for downstream communication. The appliance 140 can be any device such as customer premises equipment, including an electronic device that is part of a network (e.g., a communication network, a home network, a utilities network, or combinations thereof) and can have various levels of computational capabilities. In certain embodiments, the electronic device can be a terminal display device without computing functionality that renders a previously decoded signal. For example, the appliance 140 can be at least one of a terminal display device, a digital terminal adaptor (DTA), a set top box (STB), an IP-enabled television, a personal computer, and so forth. In one embodiment, DL 134 can transport data and signaling in-band, without availability of an out-of-band channel for signaling. In such embodiment or in an alternative embodiment, appliance 140 can be a one-way device that cannot transmit upstream communications to network B 130.
Consumption of content (linear programming, non-linear assets, etc.) at appliance 140 can be controlled or supplemented through device 110. In one aspect, device 110 can access network B 130 and leverage data management functionality and control functionality provided by the network B 130 and associated with a service (e.g., digital television service) consumed by appliance 140. In one exemplary scenario related to digital television, device 110 can exchange data and signaling with network B 130, via network A 120, as part of an asset discovery 116 in which device 110 can query networks 120 and/or 130, or an asset storage location, for an asset available for consumption, such as media content (music, video, advertisement, notifications (e.g., stock option quotes, location-based services, . . . ), etc.). Assets available for consumption can include content assets and management assets. Here, a content asset can be a linear-programming asset or a non-linear asset. Thus, a content asset of the disclosure can convey content such as media that is part of linear programming or non-linear programming, whereas a management asset provides control functionality that, in response to execution, for example, by a processor, regulates consumption of content. Such control functionality can include changing a channel, advancing content, rewinding content, terminating rendering of content, pausing content streamed live, recording content, and the like. Accordingly, the asset request 118 can comprise a request for a content asset or a management asset.
In response to such query, for example, device 110 can receive data indicative of a plurality of assets available for consumption of media content. Access to such assets can permit, at least in part, device 110 to select a specific asset for consumption. In one aspect, device 110 can deliver an asset request 118 (or a message 118) to network B 130, wherein the asset request 118 can convey a command for consumption of an asset (rendering of a PPV program, pausing a live media streaming, a channel change, etc.) of the plurality of assets. Such command is referred to herein as control request and can include request for content assets and management assets. As described herein, in response, the network 130 can transmit content 138 and/or signaling 136 to the appliance in accordance at least in part with the control request.
In another aspect, device 110 can transmit an asset request 118 that can convey a command for synchronizing a channel pathway for communication of data and/or signaling among the device 110 and the appliance 140. Such command is referred to herein as synchronization request. The channel pathway can comprise a virtual channel or a downstream frequency carrier in a channel plan (e.g., a predetermined non-empty set of downstream frequencies available to a service group) associated with the appliance 140. In response to synchronization request, the network B 130 can configure the virtual channel or the downstream frequency carrier as the channel employed for communicating data and/or signaling from the device 110 to the appliance 140. In an exemplary implementation, by synchronizing such channel pathway among the appliance 140 and the device 110, data or signaling, or both, can be transmitted in-band from the device 110 to the appliance 140, without reliance, for example, on transmissions in all downstream frequencies of a service group associated with the device.
Device 110 can categorize (through use of metadata, for example) the asset request 118 according to at least two message types. As described herein, categorization of the asset request 118 can permit network B 130, or a component therein, to implement indirect control of media consumption at appliance 140 efficiently. In one scenario, device 110 can assign a first identifier (e.g., metadata) to an asset request 118 that conveys a control request. The first identifier can convey that the asset request 118 is a control message. In another scenario, device 110 can assign a second identifier (e.g., metadata) to an asset request 118 that conveys a synchronization request. The second identifier can convey that the asset request 118 is a synchronization message.
In one scenario, a command for consumption of an asset can include a channel change request. As described herein, network B 130 can convey such command to the appliance 140 as part of signaling 136. The channel change request can include a request for a data stream associated with media content being consumed at the appliance 140, the request comprising, for example, a medium access control (MAC) address of the appliance, and at least one of a virtual channel or a frequency carrier in a channel plan that is part of the plurality of assets. In another scenario, a command for consumption of an asset can include an instruction to control a data stream associated with media content being consumed at the appliance 140. The instruction can be at least one of a first instruction to advance the media content associated with the data stream, a second instruction to rewind the media content associated with the data stream, or a third instruction to terminate rendering, at the appliance 140, the media content associated with the data stream.
Device 110 can communicate with network A 120 or network B 130, or both, according to various packet-switching (PS) communication protocols supported by one or more of such networks. For instance, the various packet-switching communication protocols can include one or more of an Ethernet protocol format; an internet protocol (IP) format, such as IPv4 and IPv6, or the like; or a user datagram protocol (UDP) format. Accordingly, in one aspect, device 110 can compose the asset request 118 according to at least one of such protocols.
Network nodes, or network elements, in core network 210 can be functionally coupled through a bus 226, which enables exchange of information (e.g., data or signaling, or both) among server(s) 214, gateway node(s) 218, and network repository 224. Bus 226 can include a plurality of reference links (Cx, Cr, Dh, Dx, Gm, Ma, Mg, etc.), and related components, and conventional bus architectures such as address buses, system buses, and the like.
Distribution platform 230 can comprise one or more signal processing component(s) (such as asset resource manager 234, asset control unit 238, and asset source unit 242, and other components not shown) that can receive and operate on an information stream, such as a data stream, a signaling stream, or a combination thereof. In one aspect, such component(s) can perform one or more operations on the information stream, such encoding, modulation, multiplexing, up-conversion, combination, and the like. Architecture of distribution platform 230 can be specific to the implemented modality exploited for transmission of the information stream. Such modality can include wired delivery or wireless delivery, and specific protocols for transmission of information such as packet-switched communication, circuit-switched communication, or the like. In one embodiment, at least one of such signal processing component(s) can embody a termination system (TS), such as, in one type of network, a cable modem termination system (CMTS). In another embodiment, at least one of the one or more signal processing components of distribution platform 230 can embody a network router or a network switch (e.g., a digital subscriber line access multiplexer (DSLAM)) for transmission of information streams based on a PS communication protocol, such as internet protocol (IP) (e.g., IPv4 or IPv6). As illustrated, the distribution platform 230 can comprise a group of one or more originating node(s) 246 that can transmit the information stream. In certain embodiments, each originating node of the group of one or more originating node(s) 246 can embody an edge quadrature amplitude modulation (QAM) node. In other embodiments, each edge originating node of the group of one or more originating node(s) 246 can embody a device that consolidates the functionality of a termination system (e.g., a CMTS) and an edge QAM node. In other embodiments, each originating node of the group of one or more originating node(s) 246 can embody a network router (e.g., a broadband remote access server (BRAS)) or network switch (e.g., a DSLAM) for transmission of information streams based on a PS communication protocol (e.g., internet protocol). While illustrated as a single block, in one or more embodiment(s), distribution platform 230 can be distributed, having a centralized deployment site (or plant) and a plurality of hub sites (also referred to as sites). In such embodiment(s), each one of the hub sites can comprise an edge originating node of the group of one or more edge originating node(s) 246.
Distribution platform 230 can receive data (data flows, audio signals, video signals, any combinations thereof, etc.) and signaling (control instructions, clock signals, etc.) from a functional element that is, for example, part of core network platform 210 or that is functionally coupled thereto. In one scenario, the functional element can be a server that supplies a combination of audio signal and video signal, such as an audiovisual signal comprising a video asset. The server can be, for example, a content server for pay-per-view programming or video-on-demand assets, an application server, a data server, a telephony server, a backbone network router, or the like. In such scenario, based on the formatting of the audiovisual signal, one or more signal processing component(s) (not shown) in the distribution platform 230 can process (encode, encrypt, modulate, multiplex, up-convert, combine) the audiovisual signal and supply a resulting audiovisual signal to an edge originating node of the group of one or more originating node(s) 246. An originating node can transmit a plurality of P (a natural number) data streams, conveying at least a portion of the audiovisual signal. It should be appreciated that in certain embodiments, the edge originating node can operate on the audiovisual signal without reliance on such one or more signal processing component(s). In another scenario, a source node (e.g., a satellite transceiver coupled to an asset source) coupled to the distribution platform 230 can generate an audiovisual signal, which can be processed by one or more processing component(s) and supplied to an edge originating node of the one or more originating node(s) 246. Such edge originating node can transmit a plurality of P data streams conveying at least a portion of the audiovisual signal.
A gateway node of the one or more gateway node(s) 218 can receive the asset request 118 and relay it to an asset resource manager 234 (e.g., a session resource manager (SRM) server) that is part of the distribution platform 230. In another implementation, a server (e.g., a proxy server) of the one or more server(s) 214 can receive the asset request 118 and relay it to the asset resource manager 234. As described herein, the asset request 118 can be a message that conveys a request for a first data stream associated with media content. In one aspect, the request can comprise one or more of at least one logical address (e.g., a medium access control (MAC) address, or an internet protocol (IP) address) associated with the appliance 140, or at least one of a virtual channel or a frequency carrier in a channel plan available for delivery of the media content. The logical address can be a unique address or a non-unique address, such as an address corresponding to a group of addresses. In another aspect, the asset request 118 can be a control message comprising an instruction to control a data stream (e.g., a multi-program transport stream (MPTS)) associated with a non-linear media asset (or, more generally, media content) wherein the instruction can be at least one of a first instruction to render the data stream, a second instruction to advance rendering of media content (e.g., a fast-forward instruction) related to the data stream; a third instruction to retreat the rendering of media content (e.g., a rewind instruction) related to the data stream; or a fourth instruction to terminate rendering the media content (e.g., a stop instruction) related to the data stream.
The asset resource manager unit 234 (also referred to as asset resource manager 234) can receive at least one message for one or more appliances (e.g., appliance 140), and can supply the at least one message to the one or more appliances. In one scenario, the at least one message can comprise a plurality of asset requests received from respective devices that are configured to indirectly control consumption of media through an appliance. As described herein, each message of the at least one message can convey a command for consuming media content through an appliance (e.g., appliance 140) of the one or more appliances. For a message that is a control message, in one implementation, the asset resource manager 234 can substantially continuously or semi-continuously supply (e.g., process and transmit) the control message to the appliance (e.g., the appliance 140) while a delivery criteria is fulfilled and, in response, the appliance can perform a specific action such as rendering indicia indicative of the control message. To at least such end, the asset resource manager 234 can retain a replica of the control message in a memory that is part of or functionally coupled to the asset resource manager 234. Such replica can be retained while a delivery criterion is fulfilled. The substantially continuous or semi-continuous transmission of the control message can be effected in-band. As an illustration, the control message can be an instruction to fast forward a video asset being rendered in a display device functionally coupled to a set-top box (e.g., appliance 140). In such case, the asset resource manager 234 can substantially continuously deliver the fast forward instruction (conveyed as part of signaling 136, for example) to the set-top box until normal rendering of the video asset is resumed (which can be an example of a delivery criterion). In response to receiving the fast-forward instruction substantially continuously, the set-top box can cause the display device to render indicia (e.g., a logo) indicative of the rendering of the video asset being advanced. In certain embodiments, such indicia can be received as part of content 138. In one embodiment, e.g., exemplary embodiment 300 illustrated in
As described herein, the appliance 140 can receive in-band signaling without an out-of-band (OOB) channel. Accordingly, a plurality of asset requests can be transmitted through available downstream frequency carriers available for delivery of data. In addition, the various transport streams (e.g., SPTSs, MPSTs) that can be consumed through deployed appliances (e.g., appliance 140) can have different amounts of available bandwidth overhead. Thus, in one aspect, prior to transmission of an asset request (e.g., asset request 118) to an appliance, the asset resource manager 234 can determine an amount of network resources (e.g., bandwidth) available for delivery of an asset request (e.g., a control message, a synchronization message). In one aspect, the asset resource manager 234 can assign a first priority to an asset request that is a control message, and a second priority to an asset request that is a synchronization message. In certain implementations, the first priority can be higher than the second priority, since a synchronization message can be delivered at a lesser rate than control messages (e.g., channel change requests). The synchronization message can be delivered at the lesser rate in view that, for example, the synchronization message is utilized once per viewing session and is transmitted to all downstream frequency channels in a service group associated with the appliance (e.g., appliance 140). Thus, communication of the synchronization message can consume a substantive amount of available bandwidth.
Based at least on the amount of such resources, the asset resource manager 234 can supply (e.g., process and transmit) the asset request. To at least such end, in one implementation, the asset resource manager 234 can combine the asset request (which can be referred to as a message) with other asset request(s). The extent of the combination of the asset request with the other asset request(s) can be established by the amount of network resources. In one aspect, the asset request can be combined with other asset requests according to categories. For example, when the asset request is a control message requesting a channel change to a specific channel, the control message can be combined with another asset request that is a channel request directed to the specific channel. In another aspect, the asset request can be combined with other asset request(s) according to the addresses of the appliances that are intended to receive the combined asset requests. For example, when the asset request is a control message requesting a specific programming, the asset request can be combined with other asset request(s) requesting such specific programming for other appliance(s). Thus, the combined asset request can be composed according to the addresses of the controlled appliances. Combining asset requests according to addresses can increase efficiency of message delivery, particularly, yet not exclusively, for unique addresses, since a substantive portion of the unique addresses address associated with the appliances being controlled are likely to be similar. In yet another aspect, the asset request can be combined with other unrelated asset request(s) to adjust to a minimum packet size (e.g., an MPEG packet size) and thus mitigate or avoid having data packet(s) padded with null bits. In addition or in the alternative, based on the amount of network resources (e.g., spectral bandwidth), the asset resource manager 234 or a functional element coupled thereto, such as an originating node of the one or more originative node(s) 246, can operate on at least one transport stream being distributed by the distribution platform 230 in order to increase the available network resources.
In certain embodiments, such as exemplary embodiment 300, asset resource manager 234 can comprise an assessment component 308 to evaluate the network resources available for transmission of a plurality of asset requests, and a messaging generator unit 312 (also referred to as messaging generator 312) to supply at least one asset request. In certain implementations, the assessment component 308 can operate on one or more transport streams to increase network resources (e.g., available bandwidth) for delivery of asset request(s).
In scenarios in which device 110 is intended to control consumption of a transport stream conveying a non-linear asset, such transport stream can generally be transmitted in a specific service group (e.g., a portion of downstream spectrum comprising one or more narrowcast channels) associated with the appliance 140. Distribution platform 230 can comprise an asset control unit 238 that can discover a service group associated with the appliance and deliver an asset request (e.g., a control message or a synchronization message) to the appliance. In addition or in the alternative, for asset requests (e.g., a control message) that select a specific non-linear asset (e.g., media-on-demand), the asset control unit 238 can determine a suitable format (e.g., video compression, video resolution, or the like) for transmission of the non-linear asset (or, more generally, data indicative of such asset) based on functional capability (computing power, processor clock, etc.) of the appliance 140. For example, in one aspect, asset control unit 238 can transmit signaling indicative of the suitable format to an asset source unit 242, which can provision and deliver the non-linear asset in such format. As an example, for an appliance 140 that is a digital terminal adaptor, the asset control unit 238 can establish that delivery of a non-linear asset be effected through a first delivery pathway comprising an originating node (e.g., an edge QAM) whereas for an appliance that is a computing device with suitable resources, the asset control unit 238 can determine that delivery of the non-linear asset be effected through a second delivery path comprising an originating node that can be a termination system, such as a cable modem termination system. Other implementations are contemplated in which the first pathway can comprise a first network router or network switch for PS communication, and the second pathway can comprise a second network router or network switch for PS communication. The first pathway and the second pathway both include data and signaling pipe 248, various functional elements of transport network 250 (e.g., an HFC network, a broadband network such as a digital subscriber line (DSL) network, or the like) and data and signaling pipe 254.
The transport network 250 can be a WAN that can be embodied in a wireless network, a wireline network, or a combination thereof, and supplies data service(s), such as television programming, video on demand, Internet service, packet-switched data or telephony, to a user location which can be stationary (e.g., a location of a CPE) or mobile (e.g., a location of mobile device). In certain implementations, transport network 250 can be embodied in an optic fiber network, a coaxial cable network, a hybrid fiber coaxial (HFC) network, or a wireless network comprising terrestrial wireless links and deep-space links (e.g., satellite links), or any combination thereof. As an illustration, in an embodiment in which the transport network 250 is an HFC network, data pipe and signaling 248 can comprise several optic fiber links and associated optical functional elements, such as downstream lasers, light amplifiers, last-mile fiber aggregator node, and the like. In addition, in such embodiment, transport network 250 can comprise various RF amplifiers and coaxial taps to respective dwellings (e.g., a stationary user location) wherein customer premises equipment (CPE), such as appliance 140, can consume a data service provided through distribution platform 230. In such embodiment, the CPE can be functionally coupled to a cable modem or other device that serves as the network gateway to the dwelling network from the transport network 250. As another illustration, in an embodiment in which the transport network 250 is a wired broadband PS network, data pipe and signaling 248 can comprise Ethernet links, and can include network routers such as BRASs and network switches, such as DSLAMs. The network switches can be functionally coupled to home gateways (e.g., DSL modems) in dwellings in which CPE (e.g., appliance 140) consume data services provided through distribution platform 230.
In certain embodiments, transmission of a channel change request can be mitigated or avoided. For example, for users who desire to control their appliances (e.g., a one-way box) with an internet-based device through a switched digital video (SDV) QAM node or a network router or network switch for PS protocol (e.g., IP) communication (both of which can be part of, for example, the one or more originating node(s) 246), channel change requests can be mitigated or avoided for linear-programming channels. Accordingly, in such scenario, insertion of discrete channel change requests into QAM downstream channels or downstream channels for PS communication can be prevented or avoided. Reducing insertion of discrete channel requests into QAM downstream channels or downstream channels for PS communication can be advantageous in embodiments in which an amount of available network resources (bandwidth, bitrate, etc.) overhead cannot be controlled through a component, such as asset resource manager 234, that operates on transport streams in order to increase such overhead.
The indirect control of an appliance (e.g., appliance 140), via, for example, the SDV QAM node or a network router or a network switch for PS protocol communication, can be more efficiently implemented in scenarios having a small population of users per originating node. In one aspect, a re-pair channel change message can be transmitted on most all QAM or IP downstream channels or downstream channels for PS communication at least once indicating an appliance (e.g., a DTA coupled to a television set) to access, for example, a specific SDV QAM node or a specific network router or a specific network switch for PS protocol communication for media content consumption. Here, the re-pair channel change message can configure, for example, a pair of the form (SDV QAM node, program number) or (IP switch, program number), wherein the program number is associated with the linear channel that transports media content. As indicated previously, the specific SDV QAM node or specific network router or specific network switch for PS protocol communication can, for example, be part of distribution platform 230. In response to transmitting (e.g., broadcasting) such re-pair channel change message, the distribution platform 230 (e.g., a local headend or hub) can control, via asset resource manager 234, for example, the amount of network resources overhead that is available. Such overhead can be associated with the small number of user devices (e.g., appliance 140) that can consume (e.g., receive) content through, for example, the specific SDV QAM node or the specific network router or the specific network switch for PS protocol communication.
In a scenario in which a user is watching a first linear channel through, e.g., a specific SDV QAM node, and a second linear channel the user desires to watch is not being transmitted (e.g., broadcast) on any SDV QAM node at an SDV system (not shown), transmission of a channel change request still can be avoided. Here, the first linear channel can have a specific program number associated therewith, and watching a linear channel refers to consuming media content, such as linear programming content, being transported (or transmitted) in the linear channel. The SDV system, which can, for example, be part of distribution platform 230, can change the linear program (e.g., linear media content) being transmitted on the specific pair (SDV QAM node, program number), causing the appliance, such as a DTA coupled to a television set, to render the desired linear program associated with the second linear channel the user desires to watch. In one aspect, such change among linear programs can result in a substantially instantaneous channel change. In another aspect, in an implementation in which, for example, the SDV system (not shown) has memory storage (e.g., a buffer) available for the SDV channel associated with an SDV QAM node, delivery of linear programming through, e.g., the SDV QAM node can be provided with live buffer support, which may not be supported by a one-way appliance such as a DTA. In an additional or alternative scenario in which the first linear channel is consumed through, for example, a specific network router or a network switch for communication, and the second linear channel is not transmitted on any network router or network node in a local distribution hub associated with such node or router, transmission of a channel change request to switch to the second channel can be avoided in substantially the same manner as described hereinbefore. In one aspect, the local distribution hub, or a suitable content delivery system therein, can change the linear program being transmitted in the specific network router or specific network switch), causing the appliance, such as a DTA coupled to a television set, to render the desired linear program associated with the second linear channel the user desires to watch. Such system can, for example, support live buffering through memory, or more generally computer-readable media, available to the specific network router or specific network switch.

In view of the various aspects of indirect control of media consumption at an appliance described herein, exemplary methods that can be implemented in accordance with the disclosed subject matter can be better appreciated with reference to the exemplary flowcharts in
The methods disclosed throughout the subject specification can be stored on an article of manufacture, such as a computer-readable storage medium, to facilitate transporting and transferring such methods to computing devices (e.g., desktop computers, mobile computers, mobile telephones, and the like) for execution, and thus implementation, by a processor or for storage in a memory.
At block 610, data indicative of a plurality of assets available for consumption of media content can be acquired, e.g., retrieved or received. In a lookup scenario, the data can be received in response to a query (or a request) for availability of such assets. In one aspect, the plurality of assets comprises at least one content asset and at least one management asset. At block 620, a first message conveying a command for consuming an asset of the plurality of assets through an appliance is transmitted. In one aspect, transmitting the first message can comprise adding a first identifier (e.g., first metadata) to the first message, the first identifier indicating the first message is a control message. In another aspect, the first message can convey a request for a first data stream (e.g., a first MPEG transport stream, either a multi-program TS (MPTS) or a single-program TS (SPTS)) associated with the media content, where the request can comprise one or more of (i) a logical address (e.g., a medium access control (MAC) address, or an IP address) of the appliance and (ii) at least one of a virtual channel or a frequency carrier (e.g., in a channel plan). As described herein, the logical address can be a unique address or a non-unique address, such as an address corresponding to a group of addresses. The frequency carrier in the channel plan can be identified by a specific name within the request. In yet another aspect, the first message can convey an instruction to control a second data stream (e.g., a second MPEG transport stream, either an MPTS or a SPTS) associated with the media content. In one scenario, the instruction can be a first instruction to advance the video content related to the second data stream. In another scenario, the instruction can be a second instruction to rewind or fast forward (e.g., using trick files) the video content related to the second data stream. In yet another scenario, the instruction can be a third instruction to terminate rendering the media content (e.g., video content, audio content) related to the second data stream. In other scenarios, the instruction can be a combination of two or more of the first instruction, the second instruction, and the third instruction.
At block 630, a second message conveying a command for synchronizing a channel pathway for communication of data and/or signaling among the appliance and a device can be transmitted. As described herein, the channel pathway can comprise a virtual channel or a downstream frequency carrier in a channel plan (e.g., a predetermined non-empty set of downstream frequencies available to a service group) associated with the appliance (e.g., device 140). In one aspect, transmitting the second message can comprise adding a second identifier (e.g., second metadata) to the second message, the second identifier indicating the second message is a synchronization message.
As described herein, the order in which blocks 610 through 630 are implemented (e.g., executed) can be different from the order illustrated in
Regarding exemplary method 700, at block 710, a first message conveying a command for synchronizing a channel pathway for communication of data and/or signaling among the appliance and a device can be transmitted. The first channel configuration can be a first virtual channel or a first frequency carrier in a channel plan (e.g., a predetermined set of downstream frequencies available to a service group) associated with the appliance (e.g., appliance 140). As described herein, in an exemplary implementation, by synchronizing such channel pathway among the appliance and the device, data or signaling, or both, can be transmitted in-band from the device to the appliance, without reliance, for example, on transmissions in all downstream frequencies of a service group associated with the device. At block 720, a second message conveying a command for switching the appliance to a specific channel configuration can be transmitted. In view of the synchronizing step, such command can be transmitted, for example, in-band via the channel pathway as opposed to OOB or via broadcasting mode. The specific channel configuration can be a virtual channel or a frequency carrier in a channel plan (e.g., a predetermined set of downstream frequencies available to a service group) associated with the appliance.
At block 810, a message conveying a command for consuming media content through an appliance is received. At block 820, an amount of network resources available for delivery of the message is determined. In one aspect, the amount of network resources can comprise an amount of bandwidth overhead available or allocated to a transport stream associated with a downstream frequency carrier. In another aspect, the amount of network resources can comprise a network load of messages conveying respective commands for consuming media content. In certain embodiments, the exemplary method 800 can include processing block that can comprise adjusting the amount of network resources in response to an outcome of the block 820. For instance, such adjusting action can comprise modifying encoding or compression, or both, of a plurality of transport streams being transmitted in downstream frequency channel(s). At block 830, a delivery priority is assigned to the message based at least on the amount network resources. In addition or in the alternative, the delivery priority can be assigned based on increasing network operation performance, such as reducing or minimizing total latency amongst transmitted packets. For example, since it generally takes longer to tune high-definition (HD) channels than standard-definition (SD) channels typically due to longer time between I frames, when the message is a channel change request to an HD channel (or an HD tune request), the message can be assigned higher priority than a SD tune request. Similarly, yet not identically, a channel change request to a service (e.g., linear programming) in the same frequency can take less time than channel change request to a service in a different frequency. Accordingly, when the message is a channel change request to a different frequency, the message can be assigned a higher priority than a channel change request within the same frequency. At block 840, the message is supplied to the appliance based at least on the amount of network resources and the delivery priority. As described herein, in certain scenarios the message can be supplied as part of in-band signals. Supplying the message can comprise processing and transmitting the message in accordance with aspects described herein, such as grouping a plurality of two or more messages and transmitting same.
