The technical field relates to digital video and audio device testing and more particularly, to apparatus, systems, and methods for providing highly scalable automated testing and monitoring of receiving devices.
In one embodiment, a plurality of automated monitoring and control system modules are individually coupled to respective receiving devices via the audio and video output ports of each respective receiving device. Each automated monitoring and control system module is also connected to a central monitoring system over a local area network (LAN) or the Internet. Each automated monitoring and control system module can send information to the centralized monitoring system regarding the model and configuration information of the receiving device to which it is connected. Then customized testing programs and scripts are automatically downloaded to each automated monitoring and control system module applicable to the particular model of the receiving device to which it is connected.
Each automated monitoring and control system module then executes the customized testing program for the respective receiving device to which it is coupled. To execute each respective customized testing program, each automated monitoring and control system module controls operation of the receiving device to which it is connected via wireless remote control commands sent from the automated monitoring and control system module to the receiving device via a wireless remote control signal. This test may be performed to simulate various commands that an end user of the receiving device would send using the receiver's remote control device. For example, such commands as changing channels, changing the volume, recording, playing, pausing, fast forwarding and rewinding of programs, selecting menu items, configuring the receiving device, and any other command that could be sent from the remote control device of the receiving device may be sent by the automated monitoring and control system module during the test execution. The automated monitoring and control system module may also control the temperature of a testing environment of the receiving device and vary AC voltages to the receiving device.
During or after running each customized testing program (e.g., by the automated monitoring and control system module sending wireless commands to the remote control receiver of the connected receiving device), each automated monitoring and control system module may also send information such as captured or stored video, audio and test results to the central monitoring system for further processing. This enables a large number of receiving devices to be tested concurrently with less manual intervention and also allows more sophisticated remote testing (e.g., while the receiver is at the end user's or customer's premises).
In another embodiment, a method for testing a receiving device is provided. The method may include aspects of the processes described above, as well as others described herein.
A device for testing a receiving device is provided. The device may include components that cause the methods described above, and others described herein, to be performed.
In another embodiment, a system for testing a plurality of receiving devices is provided. The system may include components that cause the methods described above, and others described herein, to be performed.
In another embodiment, a non-transitory computer-readable medium is provided. The non-transitory computer-readable storage medium has computer executable instructions thereon that, when executed by a computer processor, cause the processor to perform the methods described above, as well as others described herein.
The components in the drawings are not necessarily to scale relative to each other. Like reference numerals designate corresponding parts throughout the several views.
A. Environment Overview
The automated monitoring and control system module 100 may also be operably connected to a communications network 108 to send and receive information regarding the testing and monitoring of the receiving device 118 and configuration information regarding the receiving device 118. The automated monitoring and control system module 100 provides for the control of the receiving device 118 and may also provide control of a testing environment. For example, the automated monitoring and control system module may control satellite signal levels input to the receiving device 118, control and vary AC voltages to the receiving device 118, control operation of the receiving device 118 via wireless remote control commands sent from the automated monitoring and control system module to the receiving device 118, control the temperature of a testing environment of the receiving device 118, etc. The automated monitoring and control system module 100 reports performance data of the receiving device 118 over the communication system 108 to a remote monitoring system 122 and may also perform analysis of the performance data and any captured video or audio data from the receiving device 118. The automated monitoring and control system module may also request additional analysis from the monitoring system 122 over the communication system 108. This allows the automated monitoring and control system module 100 to be remotely located from the monitoring system 122. The remote monitoring system 122 may be that of the content provider 104, program distributor 106, information provider 138, receiving device 118 manufacturer (not shown) or other entity or third party.
The remote monitoring system 122 may also be a centralized monitoring system for multiple receiving devices at various remote locations, each receiving device 118 having a corresponding automated monitoring and control system module connected to the communication system 108. The remote monitoring system 122 may also provide further analysis of performance information sent from the automated monitoring and control system module 100 of the receiving device 118 or from other automated monitoring and control system module devices of other remote receiving devices. Before providing additional details regarding the operation and constitution of the automated monitoring and control system module 100, the example content distribution environment 102, within which the automated monitoring and control system module 100 may operate, will briefly be described.
In the content distribution environment 102, audio, video, and/or data service providers, such as, but not limited to, television service providers, provide their customers a multitude of video and/or data programming (hereafter, collectively and/or exclusively “programming”). Such programming is often provided by use of a receiving device communicatively coupled to a presentation device 120 configured to receive the programming.
The receiving device 118 interconnects to one or more communications media or sources (such as a cable head-end, satellite antenna, telephone company switch, Ethernet portal, off-air antenna, or the like) that provide the programming. The receiving device 118 commonly receives a plurality of programming by way of the communications media or sources described in greater detail below. Based upon selection by a user, the receiving device 118 processes and communicates the selected programming to the presentation device 120.
For convenience, the receiving device 118 may be interchangeably referred to as a “television converter,” “receiver,” “set-top box,” “television receiving device 118,” “television receiver,” “television recording device,” “satellite set-top box,” “satellite receiver,” “cable set-top box,” “cable receiver,” “media player,” and/or “television tuner.” Accordingly, the receiving device 118 may be any suitable converter device or electronic equipment that is operable to receive or playback programming. Further, the receiving device 118 may itself include user interface devices, such as buttons or switches. In many applications, a remote-control device (“remote”) 128 is operable to control the receiving device 118 and/or the presentation device 120. The remote 128 typically communicates with the receiving device 118 using a suitable wireless medium, such as infrared (“IR”), radio frequency (“RF”), or the like. The automated monitoring and control system module 100 may also have such wireless functionality to control the receiving device 118 remotely. In some embodiments, the automated monitoring and control system module 100 could also send commands to the receiving device 118 through a wired medium (e.g., Ethernet) to the receiving device 118.
Examples of a presentation device 120 include, but are not limited to, a television (“TV”), a personal computer (“PC”), a sound system receiver, a digital video recorder (“DVR”), a compact disk (“CD”) device, game system, or the like. Presentation devices 120 employ a display, one or more speakers, and/or other output devices to communicate video and/or audio content to a user. In many implementations, one or more presentation devices 120 reside in or near a customer's premises or test facilities 116 and are communicatively coupled, directly or indirectly, to the receiving device 118. Further, the receiving device 118 and the presentation device 120 may be integrated into a single device. Such a single device may have the above-described functionality of the receiving device 118 and the presentation device 120, or may even have additional functionality. Also, the presentation device 120 may be connected directly to a video output of the automated monitoring and control system module 100 instead of or in addition to being connected to the video output of the receiving device 118.
A content provider 104 provides program content, such as television content, to a distributor, such as the program distributor 106. Example content providers include television stations which provide local or national television programming, special content providers which provide premium based programming or pay-per-view programming.
Program content, interchangeably referred to as a program, is communicated to the program distributor 106 from the content provider 104 through suitable communication media, generally illustrated as communication system 108 for convenience. Communication system 108 may include many different types of communication media, now known or later developed. Non-limiting media examples include telephone systems, the Internet, internets, intranets, cable systems, fiber optic systems, microwave systems, asynchronous transfer mode (“ATM”) systems, frame relay systems, digital subscriber line (“DSL”) systems, radio frequency (“RF”) systems, and satellite systems.
In at least one embodiment, the received program content is converted by the program distributor 106 into a suitable signal (a “program signal”) that is communicated (i.e., “uplinked”) by one or more antennae 110 to one or more satellites 112 (separately illustrated herein from, although considered part of, the communication system 108). The communicated uplink signal may contain a plurality of multiplexed programs. The uplink signal is received by the satellite 112 and then communicated (i.e., “downlinked”) from the satellite 112 in one or more directions, for example, onto a predefined portion of the planet.
A receiver antenna 114 that is within reception range of the downlink signal communicated from satellite 112 receives the above-described downlink signal. A wide variety of receiver antennae 114 are available. Some types of receiver antenna 114 are operable to receive signals from a single satellite 112. Other types of receiver antenna 114 are operable to receive signals from multiple satellites 112 and/or from terrestrial based transmitters. In some embodiments, antenna 114 is a terrestrial “over-the-air” (“OTA”) broadcast antenna that is configured to receive a program signal from a terrestrial based transmitter, such as broadcast transmit tower. Furthermore, in some cases, the receiving device 118 is operable to receive signals from multiple, distinct antennas.
The receiver antenna 114 can be located at customer premises or test facilities 116. Examples of customer premises include a residence, a business, or any other suitable location operable to receive signals from satellite 112. Examples of test facilities include any location at which the receiving device 118 is tested other than at the customer premises. The received signal is communicated, typically over a hard-wire connection, to a receiving device. The receiving device 118 converts the received signal from antenna 114 into a signal and/or format suitable for communication to a presentation device 120 or another device, such as another digital video recorder or a home computing system. In some embodiments, the receiver antenna 114 may be remotely located from the customer premises or test facilities 116. For example, the antenna 114 may be located on the roof of an apartment building, such that the received signals may be transmitted, after possible recoding, via cable or other mechanisms, such as Wi-Fi, to the customer premises or test facilities 116.
The receiving device 118 may receive programming partially, or entirely, from a source other than the above-described receiver antenna 114. Other embodiments of the receiving device 118 may receive programming from program distributors 106 and/or content providers 104 via locally broadcast RF signals, cable, fiber optic, Internet media, or the like.
In addition, information provider 138 may provide various forms of content and/or services to various devices residing in the customer premises or test facilities 116. For example, information provider 138 may provide a Web page (or other information) to the receiving device 118 or other computing device. Information provider 138 may further perform or facilitate electronic commerce transactions. Information provider 138 may also provide information regarding testing or configuration of the receiving device 118 in addition to, or instead of, such information being provided by the remote monitoring system 122.
In the illustrated example, the automated monitoring and control system module 100 may monitor the receiving device 118 as it receives and processes the received program content. The automated monitoring and control system module 100 may also control the receiving device 118 by sending commands to the receiving device 118 to switch between, tune to and/or display particular received program content by sending corresponding commands to the automated monitoring and control system module 100 (e.g., by using the suitable wireless medium, such as IR, RF, or the like). In some embodiments, the automated monitoring and control system module 100 could also send commands to the receiving device 118 through a wired medium (e.g., Ethernet) to the receiving device 118. The automated monitoring and control system module 100 may also control the receiving device 118 by sending commands to the receiving device 118 to perform particular e-commerce transactions or perform other interactive operations, such as, for example, any commands that could be entered by a user via a remote control device or other interface. The automated monitoring and control system module 100 is configured to communicate testing and monitoring results of the receiving device 118 over the communication system 108 to remote entities, such as, for example, remote monitoring system 122 for further action, processing or reporting.
The above description of the content distribution environment 102, the customer premises or test facilities 116, and the various devices therein, is intended as a broad, non-limiting overview of an example environment in which various embodiments of a highly scalable automated testing and monitoring of receiving devices may be implemented.
Example embodiments described herein provide applications, tools, data structures and other support to implement highly scalable automated testing and monitoring of receiving devices. Other embodiments of the described techniques may be used for other purposes, including monitoring and testing of other receiving devices, such as audio and DVD players, digital recorders, computers, peripherals, televisions, mobile devices, telephones, and other electronic devices. In the following description, numerous specific details are set forth, such as data formats, code sequences, and the like, in order to provide a thorough understanding of the described techniques. The embodiments described also can be practiced without some of the specific details described herein, or with other specific details, such as changes with respect to the ordering of the code flow, different code flows, and the like. Thus, the scope of the techniques and/or functions described are not limited by the particular order, selection, or decomposition of steps described with reference to any particular module, component, or routine.
B. Example Receiving Device Overview
Note that one or more general purpose or special purpose computing systems/devices may be used to operate, store information regarding the receiving device 118, and communicate with the automated monitoring and control system module 100. In addition, the receiving device 118 may comprise one or more distinct computing systems/devices and may span distributed locations. Furthermore, each block shown may represent one or more such blocks as appropriate to a specific embodiment or may be combined with other blocks. Also, the receiving device 118 operation manager 222 may be implemented in software, hardware, firmware, or in some combination to achieve the capabilities described herein.
In the embodiment shown, receiving device 118 comprises a computer memory (“memory”) 201, a display 202, one or more Central Processing Units (“CPU”) 203, Input/Output devices 204 (e.g., keyboard, mouse, RF or infrared receiver, light emitting diode (LED) panel, cathode ray tube (CRT) or liquid crystal display (LCD), USB ports, other communication ports, and the like), other computer-readable media 205, and network connections 206. The receiving device 118 operation manager 222 is shown residing in memory 201. In other embodiments, some portion of the contents, some, or all, of the components of the receiving device 118 operation manager 222 may be stored on and/or transmitted over the other computer-readable media 205. The components of the receiving device 118 operation manager 222 preferably execute on one or more CPUs 203 and facilitate the receiving, decoding, processing, selecting, recording, playback and displaying of programming, as described herein.

Recorded programming may reside on the recording data repository 215 and various configuration information of the receiving device 118 may reside on the configuration information data repository 216. The configuration information may be communicated via the network connections 206 through the communication system 108 to the automated monitoring and control system module 100 to facilitate testing and monitoring by the automated monitoring and control system module or may be displayed on the display 202, the output device 204, or other display, and captured by a camera of the automated monitoring and control system module 100. The receiving device 118 operation manager 222 may also interact via the communication system 108 with other devices and systems such as the program distributor 106, remote monitoring system 122, or the like. For example, the other device may be a home computing system (e.g., a desktop computer, a laptop computer, etc.) that includes the functionality of the automated monitoring and control system module 100.
Other code or programs 230 (e.g., an audio/video processing module, a program guide manager module, a Web server, and the like), and potentially other data repositories, such as data repository 220, also reside in the memory 201, and preferably execute on one or more CPUs 203. Of note, one or more of the components in
In some embodiments, the receiving device 118 operation manager 222 includes an application program interface (“API”) that provides programmatic access to one or more functions of the receiving device 118 operation manager 100. For example, such an API may provide a programmatic interface to one or more functions of the receiving device 118 operation manager 100 that may be invoked by one of the other programs 230, the automated monitoring and control system module 100, or some other module. In this manner, the API may facilitate the development of third-party software, such as user interfaces, plug-ins, adapters (e.g., for integrating functions of the receiving device 118 operation manager 222 and automated monitoring and control system module 100 into desktop applications), and the like.
In addition, the API may be, in at least some embodiments, invoked or otherwise accessed via the automated monitoring and control system module 100, or remote entities, such as the program distributor 106 and the remote monitoring system 122, to access various functions of the receiving device 118 operation manager 222. For example, a user operating the automated monitoring and control system module 100 may select particular video or audio signals to be output at the various I/O devices 204, perform particular configurations of the receiving device 118, or perform various recording and playback operations by the receiving device 118 operation manager 222 via the API.
In an example embodiment, components/modules of the receiving device 118 operation manager 222 are implemented using standard programming techniques. For example, the receiving device 118 operation manager 222 may be implemented as a “native” executable running on the CPU 203, along with one or more static or dynamic libraries.

In general, a range of programming languages known in the art may be employed for implementing such example embodiments, including representative implementations of various programming language paradigms, including but not limited to, object-oriented (e.g., Java, C++, C#, Visual Basic.NET, Smalltalk, and the like), functional (e.g., ML, Lisp, Scheme, and the like), procedural (e.g., C, Pascal, Ada, Modula, and the like), scripting (e.g., Perl, Ruby, Python, JavaScript, VBScript, and the like), or declarative (e.g., SQL, Prolog, and the like).
In a software or firmware implementation, instructions stored in a memory configure, when executed, one or more processors of the receiving device 118 to perform the functions of the receiving device operation manager 222. In one embodiment, instructions cause the CPU 203 or some other processor, such as an I/O controller/processor, to select and present various programming. Similarly, the CPU 203 or other processor may be configured to perform other operations such as playing a recording in various playback modes.
The embodiments described above may also use well-known or other synchronous or asynchronous client-server computing techniques. However, the various components may be implemented using more monolithic programming techniques as well, for example, as an executable running on a single CPU computer system, or alternatively decomposed using a variety of structuring techniques known in the art, including but not limited to, multiprogramming, multithreading, client-server, or peer-to-peer, running on one or more computer systems each having one or more CPUs. Some embodiments may execute concurrently and asynchronously, and communicate using message passing techniques. Equivalent synchronous embodiments are also supported by a receiving device operation manager implementation. Also, other functions could be implemented and/or performed by each component/module, and in different orders, and by different components/modules, yet still achieve the functions of the receiving device 118 operation manager 222.
In addition, programming interfaces to the data stored as part of the receiving device 118 operation manager 222, can be available by standard mechanisms such as through C, C++, C#, and Java APIs; libraries for accessing files, databases, or other data repositories; scripting languages such as XML; or Web servers, FTP servers, or other types of servers providing access to stored data. The recording data repository 215 and configuration information repository 216 may be implemented as one or more database systems, file systems, or any other technique for storing such information, or any combination of the above, including implementations using distributed computing techniques.
Different configurations and locations of programs and data are contemplated for use with techniques described herein. A variety of distributed computing techniques are appropriate for implementing the components of the illustrated embodiments in a distributed manner including but not limited to TCP/IP sockets, RPC, RMI, HTTP, and Web Services (XML-RPC, JAX-RPC, SOAP, and the like). Other variations are possible. Other functionality could also be provided by each component/module, or existing functionality could be distributed amongst the components/modules in different ways, yet still achieve the functions of the receiving device 118 operation manager 222.
Furthermore, in some embodiments, some or all of the components of the receiving device 118 operation manager 222 may be implemented or provided in other manners, such as at least partially in firmware and/or hardware, including, but not limited to one or more application-specific integrated circuits (“ASICs”), standard integrated circuits, controllers (e.g., by executing appropriate instructions, and including microcontrollers and/or embedded controllers), field-programmable gate arrays (“FPGAs”), complex programmable logic devices (“CPLDs”), and the like. Some or all of the system components and/or data structures may also be stored as contents (e.g., as executable or other machine-readable software instructions or structured data) on a computer-readable medium (e.g., as a hard disk; a memory; a computer network, cellular wireless network or other data transmission medium; or a portable media article to be read by an appropriate drive or via an appropriate connection, such as a DVD or flash memory device) so as to enable or configure the computer-readable medium and/or one or more associated computing systems or devices to execute or otherwise use or provide the contents to perform at least some of the described techniques. Some or all of the system components and data structures may also be stored as data signals (e.g., by being encoded as part of a carrier wave or included as part of an analog or digital propagated signal) on a variety of computer-readable transmission mediums, which are then transmitted, including across wireless-based and wired/cable-based mediums, and may take a variety of forms (e.g., as part of a single or multiplexed analog signal, or as multiple discrete digital packets or frames). Such computer program products may also take other forms in other embodiments. Accordingly, embodiments of this disclosure may be practiced with other computer system configurations.

The Ethernet transceiver 433, for example, may be a BCM5481 10BASE-T/100BASE-TX/1000BASE-T Gigabit Ethernet transceiver, available from Broadcom Corporation, with headquarters in Irvine, Calif., USA. However, other types of Ethernet transceivers to enable uplink and general Gigabit Ethernet connectivity applications or for otherwise sending and receiving network traffic, or other types of network transceivers, may be utilized to communicate with the receiving device 118, communication system 108, or other device under test. In addition, the communications signal 339 (corresponding to the output of modem 338 of the receiving device 118) is operably provided to a Digital input/output (IO) 423 of the codec 438 to receive and send further information regarding the state or operations of the receiving device 118.
The thermometer output signal 326 in provided as input to the temperature sensor 325. The output of the temperature sensor 325 is operably connected to a pulse width modulation/analog to digital converter (PWM/ADC) 428 of the codec 438 to provide signal processing between the temperature sensor 325 and the microcontroller 425. The heater control module 328 cooling fan control module 331 receive control signals from the microcontroller 425 based on the input from the temperature sensor 325. Also, a digital input/output (IO) 429 of the codec 438 is operably connected to the input of the IR blast diode remote control signal generator 322 to generate the IR wireless signal 323 to send infrared remote control commands to the receiving device 118 or other device under test.

The system bus 441, for example, may be an Inter-Integrated Circuit (I2C) bus, which enables communication between components residing on the same circuit board, and is available from NXP Semiconductors. However, other system buses that enable communication between various components of the automated monitoring and control system module 100 may also be utilized.
The Video output 440 is operably connected to an input of an HDMI transmitter 424 and is operably connected to an HDMI output port 426 from which the which the video output signal 334 is output, or is alternatively input directly to an integrated digital video display. The HDMI transmitter, for example, may be an AD9889B HDMI/DVI transmitter available from Analog Devices, Inc.

The microcontroller 425 is operably connected to and in operable two-way communication with one or more user input devices and/or output displays 427 (e.g., a touch-screen, keypad, LED display, liquid crystal display (LCD), other alphanumeric output display, or any combination thereof) enabling a user to enter input to the automated monitoring and control system module 100 to control operation of the automated monitoring and control system module 100, display test results, error messages, diagnostic information, etc., of the receiving device 118, other device under test, the automated monitoring and control system module 100 itself, or any combination thereof. The one or more input devices and/or output displays 427 may be integrated with the automated monitoring and control system module 100 or alternatively connected to the automated monitoring and control system module 100 as one or more external peripheral devices.
The microcontroller 425 of the automated monitoring and control system module may monitor the various video audio and inputs, switching to each different input as needed in a predefined pattern, switching matrix, or in a round-robin fashion, for example. The microcontroller 425 may save particular images, image sequences, or audio to memory of the microcontroller 425, to determine whether various error conditions are present. Such error conditions may include data received indicating a stuck or frozen screen of display 120, lost power, hardware malfunction, lost signal, distorted signal, noise detection, etc. The microcontroller 425 may also detect and store the testing environment conditions (e.g., temperature) during failure conditions and also duplicate such conditions to reproduce the failure on the same receiving device 118 or other devices under test. Test results and testing instructions, programs or scripts may also be communicated over the communication system 108 (shown in

In some embodiments, the automated monitoring and control system module control software includes an application program interface (“API”) that provides programmatic access to one or more functions of the automated monitoring and control system module 100. For example, such an API may provide a programmatic interface to one or more functions of the automated monitoring and control system module 100 that may be invoked by one of the other programs, an external central monitoring system, or some other module.

In a software or firmware implementation, instructions stored in a memory configure, when executed, one or more processors of the microcontroller 425 to perform the functions of the automated monitoring and control system module control software. In one embodiment, instructions cause a processor of the microcontroller 425, or some other processor, such as an I/O controller/processor, to select and perform various testing, monitoring, communications, analysis or other operations.

Other variations are possible. Also, other functionality could be provided by each component/module, or existing functionality could be distributed amongst the components/modules in different ways, yet still achieve the functions of the automated monitoring and control system module 100.
Furthermore, in some embodiments, some or all of the components of the automated monitoring and control system module control software may be implemented or provided in other manners, such as at least partially in firmware and/or hardware, including, but not limited to, one or more application-specific integrated circuits (“ASICs”), standard integrated circuits, controllers (e.g., by executing appropriate instructions, and including other microcontrollers and/or embedded controllers), field-programmable gate arrays (“FPGAs”), complex programmable logic devices (“CPLDs”), and the like. Some or all of the system components of the automated monitoring and control system module 100 and/or data structures may also be stored as contents (e.g., as executable or other machine-readable software instructions or structured data) on a computer-readable medium (e.g., as a hard disk; a memory; a computer network or cellular wireless network or other data transmission medium; or a portable media article to be read by an appropriate drive or via an appropriate connection, such as a DVD or flash memory device) so as to enable or configure the computer-readable medium and/or one or more associated computing systems or devices to execute or otherwise use or provide the contents to perform at least some of the described techniques.

E. Example System for Simultaneous Testing and Monitoring of Multiple Receiving devices
Each automated monitoring and control system module (automated monitoring and control system module 1100a, automated monitoring and control system module 2100b, . . . , automated monitoring and control system module n 100c) is operably connected to the network switch 507 (e.g., via the corresponding network interface of each automated monitoring and control system module). A centralized monitoring system 508 (e.g., including a network-enabled computing system) is also connected to the network switch 507. The centralized monitoring system 508 receives raw test result data from each automated monitoring and control system module (automated monitoring and control system module 1100a, automated monitoring and control system module 2100b, . . . , automated monitoring and control system module n 100c) and provides further analysis of the received test result data. The centralized monitoring system 508 may also communicate with each individual automated monitoring and control system module (automated monitoring and control system module 1100a, automated monitoring and control system module 2100b, . . . , automated monitoring and control system module n 100c) via the network switch 507 to provide test instructions, monitoring instructions or other data, programs, scripts or parameters to the respective automated monitoring and control system module based on the particular diagnostic, monitoring or test data received from the respective automated monitoring and control system module and its connected receiving device 118.
For example, if a particular receiving device (e.g., receiving device 2118b) fails, the automated monitoring and control system module 2100b will detect the failure, fail condition, capture relevant video, audio, IR and RF, and other relevant data and communicate this to the centralized monitoring system 508 along with data identifying or otherwise regarding the particular receiving device 2118b. The centralized monitoring system 508 may analyze and interpret this data in response to receiving the data communicated from the automated monitoring and control system module 2100b or other request from the automated monitoring and control system module 2100b. The centralized monitoring system 508 may then send customized testing and monitoring data to the automated monitoring and control system module 100b to further test and/or monitor the receiving device 2118b in a particular manner to catch the failure again, send particular commands to the receiving device 2118b, and/or create testing environment conditions for receiving the device 2118b to reproduce the failure, or to perform other specified tests. The centralized monitoring system 508 may also compile all the raw testing and monitoring data of the receiving devices (receiving device 1118a, receiving device 2118b, . . . , receiving device n 118c) for further collective analysis, processing and reporting.
An Intranet monitoring system 509 may also be connected to the network switch 507. The Intranet monitoring system 508 may also receive raw test result data from each automated monitoring and control system module (automated monitoring and control system module 1100a, automated monitoring and control system module 2100b, . . . , automated monitoring and control system module n 100c) and provide further analysis of the received test result data and may be located in a different location or building on the testing premises or facility (e.g., on a local area network or wide area network).
One or more remote monitoring systems (e.g., remote monitoring system 122a and remote monitoring system 122b) may also be in operable communication with each automated monitoring and control system module (automated monitoring and control system module 1100a, automated monitoring and control system module 2100b, . . . , automated monitoring and control system module n 100c) over a communication system 108 (e.g., the Internet) to which the network switch 507 is connected. In this manner, some or all of the testing and monitoring functionality can be controlled at locations remote from the location of the particular receiving device being tested. For example, as shown in
Some or all of the functionality of the centralized monitoring system 508 may be present in the one or more remote monitoring systems 122a, 122b. Also, pre-programmed scripts may be downloaded to any particular automated monitoring and control system module that would exercise the connected respective receiving device 118 via the network switch 507 from the centralized monitoring system 508, intranet monitoring system 509, or one or more remote monitoring systems 122a, 122b over the communication system 108, as explained in further detail below.
F. Example Monitoring and Control System Processes
At 602, the automated monitoring and control system module 100 detects the presence of video from the connected receiving device 118. For example, the presence of video may be detected at any of the video inputs to the automated monitoring and control system module 100 connected to a corresponding video output of the receiving device 118.
At 604, the automated monitoring and control system module 100 or a monitoring system connected to the automated monitoring and control system module 100 requests the system information screen from the receiving device 118. The automated monitoring and control system module 100 may capture the system information screen from the receiving device 118 by sending the appropriate commands to the receiving device 118 via its IR or RF remote control transmitter to the receiving device 118 to display its system information screen.
At 606, once the automated monitoring and control system module 100 has stored the system information screen data from the receiving device 118, relevant receiving device 118 information (e.g., the model type, integrated receiver decoder (IRD) number, conditional access identification (CAID) number, or other identification number or code is automatically collected from the stored system information screen through automated optical character recognition. This collection of the relevant receiving device 118 information from the stored system information screen data may be performed by the automated monitoring and control system module 100 itself, or the stored screen data may be sent to a monitoring system connected to the automated monitoring and control system module 100 over a network or other communication system 108, which will then perform the collection of the relevant receiving device 118 information from the stored system information screen data.
This determination of the relevant receiving device 118 system information provides the ability to provide customized tests, test programs and test scripts from a remote central server or monitoring system. For example, if newly updated test programs become available for a particular model of a receiving device, these new test programs may be stored on one central server and then downloaded to individual automated monitoring and control system modules that are coupled to the particular receiving device as needed or on demand.
In particular, if a particular receiving device fails, the automated monitoring and control system module 100 will detect the failure, fail condition, store relevant video, audio, IR and RF, and other relevant data and communicate this to the centralized monitoring system 508 along with data identifying or otherwise regarding the particular receiving device 2188b. The centralized monitoring system 508 may analyze and interpret this data in response to receiving the data communicated from the automated monitoring and control system module 100 or other request from the automated monitoring and control system module 100.
In response to and/or based on based on interpreted test result data, the centralized monitoring system 508 or a technician may then build new, updated or otherwise customized test programs for that specific model of receiving device 118 and possibly other specific models of receiving devices. The centralized monitoring system 508 may then send customized testing and monitoring data to various automated monitoring and control system modules depending on the receiving device 118 model or other receiving device 118 information received the particular automated monitoring and control system module. The customized test programs may further test and/or monitor the applicable receiving device 118 in a particular manner to catch the failure again, detect other particular failures, send particular commands to the receiving device 118, and/or create testing environment conditions for receiving the device 118 to reproduce the failure, or to perform other specified tests.
At 608, the automated monitoring and control system module 100 thus downloads the appropriate testing instructions, program, script or other testing information appropriate to the particular model of the receiving device 118 or according to other configuration information of the receiving device 118. For example, this testing information may be downloaded from the centralized monitoring system 508, intranet monitoring system 509, or one or more other remote monitoring systems (e.g., remote monitoring systems 122a or 122b) over the communication system 108.
Alternatively, the automated monitoring and control system module 100 may have a number of testing programs scripts or other testing information stored locally on the automated monitoring and control system module 100 appropriate for the particular connected receiving device 118 and the automated monitoring and control system module 100 may select the applicable testing scripts or other testing information based on the particular model of the receiving device 118 or according to other configuration information of the receiving device 118 collected, stored or otherwise read from the system information screen of the connected receiving device 118. If the testing programs scripts or other testing information stored locally on the automated monitoring and control system module 100 is outdated, insufficient, or is not found, the automated monitoring and control system module 100 may then proceed to download the updated or otherwise applicable testing programs from the centralized monitoring system 508.
Additionally, other methods for acquiring the appropriate testing scripts or other testing information may be used in addition to or instead of storing the system information screen data may include reading information stored within the memory of the receiving device 118 communicated to the automated monitoring and control system module 100 via various other connections between the automated monitoring and control system module 100 and the connected receiving device 118 including, but not limited to USB connections, network connections (e.g., Ethernet), short-range wireless connections, other serial connections, etc.
At 702, the automated monitoring and control system module 100 performs tests and monitors video and audio operation of the connected receiving device 118 using the downloaded customized testing program, script or other testing information. For example the downloaded program may be run using the microcontroller 425 of the automated monitoring and control system module 100 as described above.
To execute each respective customized testing program, the automated monitoring and control system module 100 controls operation of the receiving device 118 to which it is connected via wireless remote control commands sent from the automated monitoring and control system module 100 to the receiving device 118 via a wireless remote control signal. This testing program may be performed to simulate various commands that an end user of the receiving device 118 would send using the receiver's remote control device. In particular, the automated monitoring and control system module 100 may control the receiving device 118 via an IR wireless signal 323 output from IR blast diode 322 in the same manner or a manner similar to a corresponding remote control device 128 (shown in
At 704, the automated monitoring and control system module 100 determines whether an error has been detected. For example, the microcontroller 425 of the automated monitoring and control system module 100 may monitor the various video audio and inputs from the receiving device 118 to the automated monitoring and control system module 100, switching to each different input as needed in a predefined pattern, switching matrix, or in a round-robin fashion. The microcontroller 425 may save particular images, image sequences, or audio to memory of the microcontroller 425, to determine whether various error conditions are present. Such error conditions may include data indicating loss of power, hardware malfunction, a stuck or frozen screen, command failure, lost signal, distorted signal, noise, etc. The microcontroller 425 may also detect and store the testing environment conditions (e.g., temperature) during failure conditions and also duplicate such conditions to reproduce the failure on the same receiving device 118 or other devices under test. If an error has been detected the process continues to 706 and if an error is not detected the process continues to 702.
At 706, the automated monitoring and control system module 100 automatically notifies a monitoring computer of the error and may provide additional relevant information to the monitoring computer regarding the error or the receiving device 118, including, but not limited to captured or stored video data, audio data, and IR or RF data from the receiving device 118. The monitoring computer may be that of the centralized monitoring system 508, intranet monitoring system 509, or one or more other remote monitoring systems (e.g., remote monitoring systems 122a or 122b). The detected error and additional relevant information may be communicated over the communication system 108 (shown in
At 708, the monitoring computer performs further processing and analysis based on the notification received and any relevant information sent to the monitoring computer regarding the error or the receiving device 118. This relevant information may include, but is not limited to captured or stored video data, audio data, and IR or RF data from the receiving device 118. For example, this further processing and analysis may be detailed audio and video quality analysis of the received captured video, audio and IR or RF data, testing environment analysis, and/or collective analysis including data received from other automated monitoring and control system modules regarding other respective receiving devices connected to the other automated monitoring and control system modules.
In one embodiment, the monitoring computer or a technician may build new, updated or otherwise customized test programs based on the notification received and the relevant information sent to the monitoring computer regarding the error or the receiving device 118. The monitoring computer may then send customized testing and monitoring data to various automated monitoring and control system modules depending on the receiving device 118 model or other receiving device 118 information received the particular automated monitoring and control system module. The customized test programs may further test and/or monitor the applicable receiving device 118 in a particular manner to catch the failure again, detect other particular failures, send particular commands to the receiving device 118, and/or create testing environment conditions for receiving the device 118 to reproduce the failure, or to perform other specified tests. In this way, the same automated monitoring and control system module may be moved from one receiving device 118 to another and still acquire the newly updated or customized test programs or scripts for the specific receiving device 118 model to which it is currently connected.
