The subject disclosure relates to automated media content replacement.
Reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The subject disclosure describes, among other things, illustrative embodiments for an intelligent multi-switch that reacts to an impairment in reception of original media content from a satellite and/or terrestrial media feed by applying substitute media content from another source, such as a corresponding Internet feed. The multi-switch can also react to a resumption in availability of the original media content by returning to the satellite/terrestrial feed. The multi-switch can be IP enabled and include discrete signal detection to accurately predict impairments to received media content services. Other embodiments are described in the subject disclosure.
One or more aspects of the subject disclosure include a system including a switch, a processor in communication with the switch and a memory that stores executable instruction. The instructions, when executed by the processor, facilitate performance of operations that include receiving a channel indicator of a media processing device of a subscriber. The channel indicator corresponds to a satellite service channel of a number of satellite service channels, wherein the satellite service channel provides a first version of a media content item processed by the media processing device for presentation. A terrestrial service channel of a number of terrestrial service channels is identified, that presents a second version of the media content item. Unavailability of the satellite service channel to the media processing device is detected. The switch is controlled to the terrestrial service channel of the number of terrestrial service channels, wherein the second version of the media content item is not, prior to the controlling of the switch, processed by the media processing device for presentation. Subsequent processing of the second version of the media content item by the media processing device is facilitated by replacing the first version, responsive to the detecting of the unavailability of the satellite service channel.
One or more aspects of the subject disclosure include a process that detects, by a device comprising a processor, a first tuning state of a media processing device of a subscriber. The first tuning state includes a satellite service channel of a number of satellite service channels, wherein the satellite service channel presents a media content item. The media content item is presented to the media processing device. A terrestrial service channel of a number of terrestrial service channels is determined that provides a substitute media content item. The terrestrial service channel of the number of terrestrial service channels is accessed. An unavailability of the satellite service channel to the media processing device of the subscriber is detected and subsequent processing of the substitute media content item by the media processing device is facilitated by replacing the media content item, responsive to the detecting of the unavailability of the satellite service channel.
One or more aspects of the subject disclosure include a machine-readable storage medium, having executable instructions that, when executed by a processor, facilitate performance of operations. The operations include determining a first tuning state of a media processing device of a subscriber, wherein the first tuning state includes a satellite service channel of a number of satellite service channels, wherein the satellite service channel presents a first media content item. The first media content item is processed by the media processing device for presentation. A terrestrial service channel of a number of terrestrial service channels is identified that provides a second media content item. The terrestrial service channel of the number of terrestrial service channels is accessed, wherein the second media content item is not initially processed by the media processing device for presentation. An unavailability of the satellite service channel to the media processing device is determined and facilitation of subsequent processing of the second media content item by the media processing device by replacing the first media content item, responsive to the determining of the unavailability of the satellite service channel.
One such means of interference is related to the sun 114. The satellite terminal 106 typically has a highly directional antenna that is aimed at a location of the satellite 102. Under certain astronomical conditions, the sun may fall within the same region covered by the satellite terminal 106 antenna. Namely, the satellite falls on a line connecting the satellite antenna and the sun. This can be referred to as sun fade, sun transit, sun outage or solar conjunction. Such conditions can occur multiple times per year, for a period of about several minutes or more during which reception of the satellite signal is impeded, degraded or otherwise unavailable. In some instances, e.g., depending upon antenna mis-pointing, link margin, actual element performance and so forth, the durations of any single outage can be greater than 10 minutes. Fortunately, sun fade can be predicted with a high degree of precision based on locations of the satellite 102 and the satellite terminal 106. Sun interference prediction calculators are readily available, such as a calculator available online from INTELSAT, at http://www.intelsat.com/tools-resources/satellite-data-tools/sun-interference-calculator/.
It is generally understood that adverse weather conditions can also affect the quality of satellite signal reception. For example, heavy rains 112 can attenuate the satellite signal enough to result in noticeable degradation of image quality. In extreme cases, the reception can be effectively disrupted. Satellite signal reception quality also can be affected by water or snow/ice accumulating over the surface of the satellite terminal antenna.
In more detail, the satellite terminal 106 includes a satellite dish antenna 105 and a low-noise amplifier/block down-converter (LNB) 107. The dish antenna 105 is typically mounted external to a subscriber's premises and receives RF signals 104 from one or more satellites. The received satellite signals 104 are passed to the LNB 107, and an amplified, filtered and down-converted, e.g., removing an RF carrier. The down-converted signals 109 are provided to a satellite receiver, typically within the subscriber's premises. Some premises can include multiple receivers or set-top boxes (STBs) 110a, 110b, 110c, 110d (generally 110) receiving the down-converted signals 109 from an RF distribution device.
If the satellite terminal 106 provides a single output, the RF distribution device can include an RF splitter. More typically, the satellite terminal 106 provides multiple outputs. In the illustrative example, a multi-switch 108 is provided to route the down-converted signals to the appropriate STB 110. It is generally understood that the same dish antenna can receive satellite signals 104 from more than one satellite. Alternatively or in addition, the same premises can have more than one satellite antennas, e.g., pointing to different satellites and/or operating in different frequency bands. In such situations, each of the inputs of the multi-switch 108 is dedicated to a respective one of the received satellite signals 104. In some embodiments, one of the inputs of the multi-switch can receive inputs from a terrestrial antenna, e.g., receiving a local terrestrial wireless broadcast of television programming. For example, a “3 In-4 Out” multi-switch can receive inputs from two block-down-converted satellite signals 109 and one local terrestrial wireless broadcast signal (not shown). The multi-switch 108 provides four output terminals that can support up to four satellite receivers, or STBs 110, as shown.
The satellite receiver or STB 110 can include one or more of a de-scrambler or decryption module to unlock or otherwise provide access to media content offered by a satellite service provider. The STB 110 can include a tuner that responds to an input from a user that tunes the STB 110 to one of a number of available satellite service channels. In some instances, the block down-conversion of the LNB 107 provides multiple satellite service channels to each STB 110, allowing for selection of a particular channel to occur within the STB 110. A decoder decodes encoded channel signals, e.g., converting digital MPEG-2, H.264 or MPEG-4 signals to another format, such as analog NTCS format, HDTV format, and the like. It is understood that the down-converted RF signal can support multiple channels simultaneously, e.g., being distributed by the RF distribution network for processing by multiple satellite receivers.
In the illustrative embodiment, the system 100 also includes an intelligent multi-switch 116. The intelligent multi-switch 116 receives media content from one or more alternate sources 118 and selectively provides the alternative media content to one or more of the STBs 110. For example, the intelligent multi-switch 116 provides the alternative media content 118 to the STBs 110 during occurrences of interference that might otherwise degrade or prevent reception of the satellite signal 104. In some embodiments, the intelligent multi-switch 116 identifies alternate media content based on the particular media content being consumed or otherwise presented to the STBs 110. Indication of media content being presented to the STBs 110 can be determined from one or more of a channel indicator, an Electronic Programming Guide (EPG), a program recording schedule for STBs 110 that include Digital Video Recorders (DVR), and the like.
In some embodiments, the intelligent multi-switch 116 is IP enabled and has discrete signal detection that applies the content from a corresponding internet feed 118 (fed to IP multi-switch) and switches back to the satellite/terrestrial feed 109 when certain impairments come and go. Typically this type detection can be a signal frequency detector. The accuracy associated with the prediction of rain fade at one frequency based on the rain fade measured at another frequency is on the order of +/−2 dB. Thus effective fade detection requires fade measurements at only one frequency. However there are several detection methods to accomplish the switch, such as indication of a signal to noise ratio, a bit error rate, an error correction performance metric, and so forth.
The terrestrial portion 200 also includes an intelligent multi-switch 216. The intelligent multi-switch 216 is in communication with one or more of the STBs 210 and one or more network-accessible alternate content sources 218. Alternatively or in addition, the intelligent multi-switch 216 is in communication with one or more of a program schedule and/or service directory 224, a weather service 226 and a solar calculator 227. The STBs 210, in turn, include an RF input terminal 220a, 220b, 220c, 220d (generally 220), and a network interface 222a, 222b, 222c, 222d (generally 222). The RF input terminals 220 are in communication with the RF distribution network 208, receiving the down-converted RF signals from the LNB 207. The network interfaces 222 are in communication with the intelligent multi-switch 216, e.g., receiving alternative media content from one of the network-accessible alternate content sources 218. In some embodiments, the multi-switch 216 is in communication with one or more of the satellite terminal 206 and the RF distribution network 208.
In operation, any operational STBs 210 that are actively receiving satellite media content from the satellite signal 204, would be tuned to a channel associated with particular media content provided on that channel. It is generally understood that the satellite service media content can be provided in a broadcast mode, e.g., according to a program lineup or schedule. Under such conditions, the program lineup can be identified by an electronic program guide identifying channels, time slots and programmed media content. Accordingly, knowledge of a tuned channel and a time is sufficient to allow for an identification of a media content item being presented on display equipment attached to the STB 210 and/or recorded at a DVR. Alternatively or in addition, the satellite signal includes metadata that includes identifying information. Different metadata can be provided for each programmed channel of the satellite service lineup, such that access to metadata of a tuned channel can identify a media content being presented on the display equipment attached to the STB 210 and/or recorded at a DVR. It is also understood that in some embodiments, satellite service media content can be provided on a pay-per view basis and/or as an on demand basis.
The intelligent multi-switch 216 can identify what media content items are being delivered to any active STBs 210, and further identify alternative media content items. The alternative media content items can include, without limitation, other versions of the same media content items. For example, a direct broadcast satellite service provider may offer some or all of their channel lineups in an ancillary service for delivery over terrestrial networks. The ancillary service can include, so-called, small screen versions of the media content items, generally intended for consumption on mobile devices. Thus, a high-definition version, including ultra-high-definition or “4K” version of a media content item might be delivered by the satellite service according to the satellite signal 204; whereas, a standard definition, low-definition or otherwise small-screen version can be provided via a cable service and/or via an IP media stream.
The intelligent multi-switch 216 can identify an impairment in delivery of media content by way of the satellite signal 204, and in response, direct the alternative media content 219 to the STBs 210 by way of the network interface 222. The alternative media content can take the form of a packet stream, e.g., a media stream according to a streaming protocol, such as MPEG-2 or MPEG-4, MP-3, and the like. The media content and the alternative media content can include, without limitation, one or more of video content, audio content, data, text, images, and the like. In some embodiments, the media content can include social media content, gaming content, e.g., multiplayer including massively multiplayer games. It is also generally understood that any media content or alternative media content can include metadata that can include descriptive information about the media content item. Descriptive information can include, without limitation, a program identifier, a program title, a program source, e.g., studio, actors in the program, a genre, viewer and/or critical reviews, an industry standard rating, e.g., general audience, mature content, language, nudity, violence, start time, end time, duration, and the like.
The intelligent multi-switch 116 detects a particular channel to which one of the STBs 110 is tuned. The intelligent multi-switch 116 can include a clock, or otherwise obtain a local time, such that the media content item or program can be determined from the channel and the time with reference to the EPG.
The intelligent multi-switch 216 can identify an impairment as a complete loss of the satellite signal 204, a reduction in RF power of the satellite signal, e.g., due to a signal attenuation as might be experienced during heavy precipitation conditions. Alternatively or in addition, the impairment can be identified by an increase in a Bit Error Rate (BER) and/or a measure of error correction performance, e.g., an increase of forward error correction. Interjection by the multi-switch 216 to provide the alternative content to the STB 210, can occur in a reactionary manner, when the signal loss and/or error performance reaches or exceeds an intolerable level. Such scenarios might result in a loss of picture and/or audio, a reduced resolution, a blank screen, and the like. Alternatively or in addition, interjection by the multi-switch 216 can occur in a predictive manner in which a trend in performance can be used to predict a future loss of signal, or increase in error performance. Such predictions can be determined from one or more of trends of measured performance, weather sensory data, weather forecasts, and or predictions, e.g., from solar calculators to predict sun fades.
Weather data and/or weather forecasts can be obtained from a weather service provider, such as the National Weather Service, a local news outlet and/or weather application programs or apps′, such as The Weather Channel®. The Weather Channel® is a registered trademark of The Weather Channel, Inc. In some embodiments, the weather information can be obtained from a local weather station or weather sensor, such as a rain gauge, a hydrometer, a barometer, or the like provided at the subscriber premises.
In some instances, the STB 210 provides an indicator that the signal loss/error performance is intolerable. This might include an application that flashes a billboard or similar message to presentation equipment indicating loss of signal and/or technical difficulties. Alternatively or in addition, one or more of the LNB 207 and the STB 210 provides a performance indicator related to the satellite signal 204 and or individual channels tuned to by the STBs 210. The signal indications can include Signal-to-Noise Ratio (SNR), BER, error corrections, and the like. The multi-switch 216 can be programmed or otherwise include logic to act upon such signal indications in order to determine when to switch between satellite service media content and any alternative media content. The programming and/or logic can implement one or more rules that determine aspects of any transitions, such as when and under what conditions to switch between the regular and alternate content. The rules can include further restrictions, such as allowed alternative content sources, blocked alternative content sources, user preferences, and the like.
It is understood that in at least some instances, the same programming content may not be available from other network sources depending on one or more of the program, the time, available sources, etc. In such instances, the multi-switch 216 can be configured to provide a suitable replacement alternative content item. Such suitable replacement content can be determined according to one or more of a genre, actor(s), producer, studio, rating, and the like. For example, if the multi-switch 216 determines that an STB 210 is tuned to a particular episode of “Modern Family,” the multi-switch can search a schedule and/or directory 224 of alternate media content to identify a suitable replacement. The suitable replacement in the illustrative example might include another episode of “Modern Family.” The other episode can be selected based on further detail, such as another episode from the same season, or close to the same season. Another episode dealing with similar subject matter, such as a story that focuses on one of the same actors can be selected, as well as other shows that may include the same actors, other family shows, and the like.
It is envisioned in at least some instances that suitable replacement content can include advertising content. The selection of any particular advertising content to be substituted during outages can be based on perceived user demographics based on the particular content tuned to by the STB 210 at the time of the outage. Alternatively or in addition, the selection of alternative content that includes advertising can be based on one or more of user preference, subscriber demographics, past viewing history, and the like.
In some embodiments, the multi-switch 216 includes a buffer, such as a circular buffer, that accepts a portion of the alternative content item. The buffer can be used to synchronize a transition between the particular media content item being presented at the STB 210 and the alternate content. For example, the buffer depth can be selected to store enough streamed media content to account for a greatest anticipated difference in timing between a satellite service presentation of a program, and a terrestrial service, “small-screen” presentation of the same show. Such delays can range from a few seconds, to tens of seconds, or more. The multi-switch can include circuitry and/or programming steps to detect or otherwise determine a time delay or time offset between the original and alternate media content items. The time delay or offset can be used to adjust the circular buffer such that alternate media content at an output of the circular buffer is approximately synchronized with the original media content presented to the STB 210. Having established synchronization, the multi-switch 216 can switch or otherwise instruct the STB 210 to switch between the original content item and the alternate content item. Such a switch can occur within the same frame, e.g., within the same “I frame” of an MPEG media stream.
The system 300 also includes one or more modulators 328 and RF switches or signal combiners 330a, 330b, 330c, 330d (generally 330). The modulator 328 is in communication with the intelligent multi-switch 316 and the RF switches/combiners 330. In operation, the intelligent multi-switch 316 accesses alternate media content, e.g., as described above in relation to
The modulator 328 receives the multicast stream, or in some instances, an analog signal comprising the alternate media content. The modulator 328 modulates the alternate media content stream onto an RF signal that can replicate the RF output signal received from the LNB 307, by way of the RF distribution network 308. In this manner the RF modulated alternate media content can be directed to one or more of the STBs 310 during any outage periods in which the original satellite service content may be degraded or otherwise unavailable. In some embodiments, the modulator 328 or another device, such as a wireless modem (not shown) can provide the alternate content wirelessly to the STBs 310.
For applications in which the RF switches/combiners 330 include controllable switches, the switches 330 can receive a control signal, e.g., from the multi-switch and/or another control device to actuate a switch to the alternate content during an interruption to the satellite service and a switch back to the original content when the satellite service has been restored. In the illustrative embodiment, the intelligent multi-switch 316 obtains alternate content for each of the set-top boxes 310. Accordingly, the intelligent multi-switch 316 provides up to four IP streams (multicast or unicast for video on demand), to the modulator 328.
Although separate RF switches/combiners 330 are illustrated, it is understood that any switching to/from alternate media content could be accommodated by the RF distribution network 308. Namely, instead of a 1×4 RF switch, the RF distribution network 308 can include a 2×4 switch capable of switching either the satellite RF signal from the LNB 307 or the alternate media content RF signal from the modulator 328 to one or more of the STBs 310. Although the modulator 328 is illustrated as having four independent RF outputs, it is understood that the modulator can modulate multiple IP packet streams onto a single RF signal, e.g., with the alternate content occupying corresponding frequency spectra to the satellite RF signal content being replaced. In this manner, the STB 310 is able to process the original satellite media content or the alternate media content without having to retune.
Alternatively, in some embodiments, in which the down-converted RF satellite signal from the LNB 307 includes encryption or scrambling, it is understood that the modulator 328 can include an encryption and/or scrambling circuitry or program steps to encrypt and/or scramble the alternate content in the same manner as applied to the original down-converted RF satellite signal. Accordingly, the STB 310 can continue to process the alternate content in a like manner, including channel tuning, decryption and/or descrambling. In other embodiments, it is understood that the alternate content can be provided without encryption and/or scrambling, even though the original signal is encrypted and/or scrambled. In such instances, the STB 310 can be programmed to detect a change in encryption and/or scrambling of the signal and process the signal accordingly. A control signal indicating whether encryption and/or scrambling should be applied can be generated with the STB 310, e.g., upon a detection that the signal is/is not encrypted/scrambled. Alternatively or in addition, such a control signal could be provided to the STB by another device, such as the modulator 328, the multi-switch 316 or some other controlling device that is aware of switchover/switchback events to/from alternate media content. An example system comprising coordination of back-up media services is disclosed in U.S. patent application, entitled “System and Method for Coordinating Back-Up Services for Land Based Content Subscribers,” having attorney docket no. 2015-0388_7785-120, and assigned application Ser. No. ______, filed on ______, incorporated herein by reference in its entirety.
A satellite channel media content item is identified at 404. A particular media content item being watched or otherwise presented or recorded on user equipment, can be identified by any of the techniques disclosed herein, including reference to an EPG based on the tuning status/channel and local time, metadata associated or otherwise provided with the media content item, and in some instances, by sampling the media content item itself. A sampling of images, textual content, and/or audio of the original media content item can be obtained and used for identification purposes.
A corresponding media content item of terrestrial channel is identified at 406. Generally, the system knows which primary service has been subscribed to for a given premises. For instances in which a companion service is available, such as the so-called “small screen” or mobile versions of a given service are available, these services can be identified as a source for corresponding or alternate media content items. In other instances, particular broadcast program might also be available as an on-demand content item. In such instances, the on-demand version can be identified as a source of a corresponding or alternate media content item. If on-demand content is used, an offset can be monitored or otherwise provided, e.g., as a pointer to a portion of the content item being presented at the time of an outage. The offset can be used to adjust download and/or playback of the on-demand content item to synchronize a transition from the broadcast to the on-demand content item in the event of an interruption.
As disclosed herein, alternative content can be identified, e.g., if corresponding version of the same content is not available. The alternative content can be identified by relationships of one or more parameters to the original content item. Such parameters can include title, characters, actors, musical scores, genre, author, producer, studio, ratings, and the like.
A satellite channel performance indicator is measured or otherwise received at 414. The satellite performance indicator can include one or more of a signal strength of the received satellite signal, a signal to noise ratio of the received signal or the down-converted signal at the LNB, and/or some other measure of performance, such as a BER, error correction performance factor and the like.
A determination is made at 416 as to whether an impairment to satellite channel has occurred. To the extent it is determined that an impairment, e.g., a loss of signal, has occurred, a switch to the alternate content, e.g., terrestrial channel, occurs at 418. Otherwise, the performance indicator continues at 414, until such time as a signal impairment is detected, if at all.
In some embodiments, a satellite channel outage forecast is obtained at 410 (shown in phantom). The forecast can include results of a solar conjunction calculation, and or a weather forecast based on locations of the satellite terminal and the corresponding satellite. It is understood that forecast can include identification of regularly scheduled maintenance, and the like. It is understood that, in some embodiments, a prediction of a loss of satellite signal can be obtained at 412 (shown in phantom). To the extent that a loss or impairment of the satellite signal is determined at 412, a switch to the alternate content occurs at 418. Otherwise, the process continues at 414, monitoring channel performance and reacting at 416 as appropriate.
In some embodiments, a portion of the corresponding media content item is buffered at 408 (shown in phantom). The buffering can be accomplished, as disclosed herein, to support a synchronization during a switch between original and alternate media content. It is understood that the buffering can be applied continuously, e.g., according to a circular buffer, such that the alternative content is available to respond to an unexpected signal outage. Alternatively, the buffering can be applied in anticipation of a scheduled and/or predicted outage. During period when an outage is not expected, there would be no need to obtain the alternate content, thereby preserving network resources.
In some embodiments, a determination is made at 420 (shown in phantom) as to whether the original satellite channel available at 420. To the extent it is determined that the original satellite channel is available, a switch back to the original satellite channel occurs at 422.
While for purposes of simplicity of explanation, the respective processes are shown and described as a series of blocks in
The IPTV media system can include a super head-end office (SHO) 510 with at least one super headend office server (SHS) 511 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent, for example, audio content, moving image content such as 2D or 3D videos, video games, virtual reality content, still image content, and combinations thereof.

The touch screen display 710 can be equipped with capacitive, resistive or other forms of sensing technology to detect how much surface area of a user's finger has been placed on a portion of the touch screen display. This sensing information can be used to control the manipulation of the GUI elements or other functions of the user interface. The display 710 can be an integral part of the housing assembly of the communication device 700 or an independent device communicatively coupled thereto by a tethered wireline interface (such as a cable) or a wireless interface.
The UI 704 can also include an audio system 712 that utilizes audio technology for conveying low volume audio (such as audio heard in proximity of a human ear) and high volume audio (such as speakerphone for hands free operation). The audio system 712 can further include a microphone for receiving audible signals of an end user. The audio system 712 can also be used for voice recognition applications. The UI 704 can further include an image sensor 713 such as a charged coupled device (CCD) camera for capturing still or moving images.
The power supply 714 can utilize common power management technologies such as replaceable and rechargeable batteries, supply regulation technologies, and/or charging system technologies for supplying energy to the components of the communication device 700 to facilitate long-range or short-range portable applications. Alternatively, or in combination, the charging system can utilize external power sources such as DC power supplied over a physical interface such as a USB port or other suitable tethering technologies.
The location receiver 716 can utilize location technology such as a global positioning system (GPS) receiver capable of assisted GPS for identifying a location of the communication device 700 based on signals generated by a constellation of GPS satellites, which can be used for facilitating location services such as navigation. The motion sensor 718 can utilize motion sensing technology such as an accelerometer, a gyroscope, or other suitable motion sensing technology to detect motion of the communication device 700 in three-dimensional space. The orientation sensor 720 can utilize orientation sensing technology such as a magnetometer to detect the orientation of the communication device 700 (north, south, west, and east, as well as combined orientations in degrees, minutes, or other suitable orientation metrics).
The communication device 700 can use the transceiver 702 to also determine a proximity to a cellular, WiFi, Bluetooth®, or other wireless access points by sensing techniques such as utilizing a received signal strength indicator (RSSI) and/or signal time of arrival (TOA) or time of flight (TOF) measurements. The controller 706 can utilize computing technologies such as a microprocessor, a digital signal processor (DSP), programmable gate arrays, application specific integrated circuits, and/or a video processor with associated storage memory such as Flash, ROM, RAM, SRAM, DRAM or other storage technologies for executing computer instructions, controlling, and processing data supplied by the aforementioned components of the communication device 700.

Upon reviewing the aforementioned embodiments, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope of the claims described below. For example, the content replacement techniques disclosed herein for DBS satellite service can be applied to other services, as well, including terrestrial services. Outages experienced in such services can be detected and/or predicted and backed up in a similar manner. That is, an intelligent switch can be provided, e.g., at customer premises, or at some other location upstream, such as at a DSLAM, VRAD, central office, or even a head end. The intelligent switch, in response to a loss of signal and/or loss of content, can provide alternate content according to the techniques disclosed herein. Consider, for example, a cable service, or other terrestrial service, such as FiOS or U-Verse that experiences a loss of signal and/or content. Substitute content obtained from an Internet version of the service, e.g., providing the same or comparable channel lineup, and provided to subscriber equipment during the detected outage. Alternatively or in addition, alternative or replacement content can be obtained from subscribe premises equipment, such as a DVR. Other alternate of replacement content can include alerts, such as weather alerts and/or emergency broadcast network content that may or may not relate to an outage being experienced. Other embodiments can be used in the subject disclosure.
In some embodiments, it is envisioned that one satellite service can be replaced with another satellite service. Such substitutions can be available for installations having multiple satellite terminals, e.g., pointing to different satellites at different orbital positions. Thus, when one satellite terminal may be experiencing a solar fade associated with a first satellite, the other satellite terminal may not be experiencing a solar fade, thus being available for service. Without limitation, transponder resources of the two different satellites may be providing satellite services of the same satellite service provider, different providers, or both. For situations in which substitute media is obtained from a different service provider, it is understood that such substitutions may require agreements for temporary provisioning of services, authorizations, assessments of fees, billing, etc.
In some embodiments, it is envisioned that one satellite service can be replaced with another satellite service of the same satellite. For example, a satellite terminal might include one dish antenna equipped with multiple feeds. The feeds can be distinguished by one or more of polarizations, frequency bands, focal positions, and the like. Consider services provided at a first frequency band and/or polarization that might be impacted by a weather event, such as precipitation. To the extent that the other service operates at a different frequency band and/or polarization, the other service may not be impacted by the same weather event, such that it would be available as a replacement. It is also understood that one dish antenna can include multiple feeds positioned at different focal locations that can point to different satellites. Accordingly, an interruption of service from one of the feeds of a first satellite can be replaced by service from another feed of another satellite. Once again, such substitutions may require agreements for temporary provisioning of services, authorizations, assessments of fees, billing, etc.
It should be understood that devices described in the exemplary embodiments can be in communication with each other via various wireless and/or wired methodologies. The methodologies can be links that are described as coupled, connected and so forth, which can include unidirectional and/or bidirectional communication over wireless paths and/or wired paths that utilize one or more of various protocols or methodologies, where the coupling and/or connection can be direct (e.g., no intervening processing device) and/or indirect (e.g., an intermediary processing device such as a router).
The machine may comprise a server computer, a client user computer, a personal computer (PC), a tablet, a smart phone, a laptop computer, a desktop computer, a control system, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. It will be understood that a communication device of the subject disclosure includes broadly any electronic device that provides voice, video or data communication. Further, while a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methods discussed herein.
The computer system 700 may include a processor (or controller) 702 (e.g., a central processing unit (CPU)), a graphics processing unit (GPU, or both), a main memory 704 and a static memory 706, which communicate with each other via a bus 708. The computer system 700 may further include a display unit 710 (e.g., a liquid crystal display (LCD), a flat panel, or a solid state display). The computer system 700 may include an input device 712 (e.g., a keyboard), a cursor control device 714 (e.g., a mouse), a disk drive unit 716, a signal generation device 718 (e.g., a speaker or remote control) and a network interface device 720. In distributed environments, the embodiments described in the subject disclosure can be adapted to utilize multiple display units 710 controlled by two or more computer systems 700. In this configuration, presentations described by the subject disclosure may in part be shown in a first of the display units 710, while the remaining portion is presented in a second of the display units 710.
The disk drive unit 716 may include a tangible computer-readable storage medium 722 on which is stored one or more sets of instructions (e.g., software 724) embodying any one or more of the methods or functions described herein, including those methods illustrated above. The instructions 724 may also reside, completely or at least partially, within the main memory 704, the static memory 706, and/or within the processor 702 during execution thereof by the computer system 700. The main memory 704 and the processor 702 also may constitute tangible computer-readable storage media.
Dedicated hardware implementations including, but not limited to, application specific integrated circuits, programmable logic arrays and other hardware devices can likewise be constructed to implement the methods described herein. Application specific integrated circuits and programmable logic array can use downloadable instructions for executing state machines and/or circuit configurations to implement embodiments of the subject disclosure. Applications that may include the apparatus and systems of various embodiments broadly include a variety of electronic and computer systems. Some embodiments implement functions in two or more specific interconnected hardware modules or devices with related control and data signals communicated between and through the modules, or as portions of an application-specific integrated circuit. Thus, the example system is applicable to software, firmware, and hardware implementations.
In accordance with various embodiments of the subject disclosure, the operations or methods described herein are intended for operation as software programs or instructions running on or executed by a computer processor or other computing device, and which may include other forms of instructions manifested as a state machine implemented with logic components in an application specific integrated circuit or field programmable gate array. Furthermore, software implementations (e.g., software programs, instructions, etc.) including, but not limited to, distributed processing or component/object distributed processing, parallel processing, or virtual machine processing can also be constructed to implement the methods described herein. It is further noted that a computing device such as a processor, a controller, a state machine or other suitable device for executing instructions to perform operations or methods may perform such operations directly or indirectly by way of one or more intermediate devices directed by the computing device.
While the tangible computer-readable storage medium 722 is shown in an example embodiment to be a single medium, the term “tangible computer-readable storage medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “tangible computer-readable storage medium” shall also be taken to include any non-transitory medium that is capable of storing or encoding a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methods of the subject disclosure. The term “non-transitory” as in a non-transitory computer-readable storage includes without limitation memories, drives, devices and anything tangible but not a signal per se.
The term “tangible computer-readable storage medium” shall accordingly be taken to include, but not be limited to: solid-state memories such as a memory card or other package that houses one or more read-only (non-volatile) memories, random access memories, or other re-writable (volatile) memories, a magneto-optical or optical medium such as a disk or tape, or other tangible media which can be used to store information. Accordingly, the disclosure is considered to include any one or more of a tangible computer-readable storage medium, as listed herein and including art-recognized equivalents and successor media, in which the software implementations herein are stored.
Although the present specification describes components and functions implemented in the embodiments with reference to particular standards and protocols, the disclosure is not limited to such standards and protocols. Each of the standards for Internet and other packet switched network transmission (e.g., TCP/IP, UDP/IP, HTML, HTTP) represent examples of the state of the art. Such standards are from time-to-time superseded by faster or more efficient equivalents having essentially the same functions. Wireless standards for device detection (e.g., RFID), short-range communications (e.g., Bluetooth®, WiFi, Zigbee®), and long-range communications (e.g., WiMAX, GSM, CDMA, LTE) can be used by computer system 700.
