Digital television adapters/customer premise equipment (DTA/CPEs) are devices configured to receive one-way communications from a headend server of a content provider via a broadcast signal. Conventionally, DTA/CPEs are simple, affordable devices with limited hardware that are capable of tuning to one radio frequency (RF) frequency. In order to set up and/or troubleshoot such devices, users must contact the content provider, which is costly and inefficient for content providers and time consuming for the users.
Embodiments of the present disclosure provide a universal messaging system that broadcasts an in-band messaging bus service (“IMB message”) to subscriber devices indicating which frequency is carrying operating data and/or firmware updates, such that subscriber devices may tune to that frequency in order to download and install the operating data and/or updated operating data without any user involvement. As a result, the present disclosure eliminates extraneous costs and inefficiencies involved with installing/updating the subscriber devices.
The communication network 106 may provide a point-to-multipoint topology for the high speed, reliable, and secure transport of information between the headend server 102 and the subscriber devices 104.1 through 104.n. As will be appreciated by those skilled in the relevant art(s), the communication network 106 may include coaxial cable, fiber optic cable, or a combination of coaxial cable and fiber optic cable linked via one or more fiber nodes, and may include frequency translation devices in support of a frequency stacking architecture, and may even include wireless links without departing from the spirit and scope of the present disclosure. In some embodiments, the headend server 102 may be implemented as a cable modem termination system (CMTS) of a cable communication system, as an optical line terminal (OLT) of a Passive Optical Network (PON), or as any other suitable centralized entity in a point-to-multipoint communication system that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the present disclosure.
The headend server 102 may be a computing device, implemented on one or more processors. In some embodiments, the headend server 102 may broadcast the IMB message to the subscriber devices 104.1 through 104.n, as discussed in U.S. patent application Ser. No. 15/373,168, filed on Dec. 8, 2016, the contents of which are hereby incorporated by reference in their entirety. In some embodiments, the headend server 102 may transmit the IMB message on a plurality of frequencies. For example, the plurality of frequencies may include one hundred fifty-eight (158) different frequencies, e.g., quadrature amplitude modulation (QAM) frequencies. It should be understood by those of ordinary skill in the arts that this is merely an example number of frequencies, and that other numbers of frequencies are contemplated in accordance with aspects of the present disclosure. In some embodiments, the IMB message may be transmitted with a long repetition rate, such as 30 Kbits/sec once every 10 seconds. However, it should be understood by those of ordinary skill in the art that the IMB message may be broadcast using more or less bandwidth and at different intervals based on the size of the IMB message.
In some embodiments, the IMB message may include information indicating which subscriber devices from among the subscriber devices 104.1 through 104.n that are targeted to receive the operating data and/or updated operating data. To achieve this, as illustrated in
In some embodiments, the locator message 140 may identify a frequency where the operating data and/or updated operating data may be downloaded. For example, the locator message 140 may include an 8-bit message instructing the subscriber devices 104.1 through 104.n where to locate the update, with a value of the 8-bit message indicating where to locate the update. In some embodiments, a first value may instruct the subscriber devices 104.1 through 104.n to retrieve the update using a QAM frequency.
In some embodiments, for the subscriber devices 104.1 through 104.n that are DTA/CPEs, the subscriber devices 104.1 through 104.n may be configured to sequentially scan the plurality of frequencies until it locates the IMB message on an active frequency for the respective subscriber device. That is, the DTA/CPEs 104.1 through 104.n may perform a channel discovery process until the DTA/CPEs 104.1 through 104.n discover the active frequency carrying the IMB message. In some embodiments, the DTA/CPEs 104.1 through 104.n may be programmed to scan the plurality of frequencies based on a predefine sequence. For example, the DTA/CPEs 104.1 through 104.n may be programmed to scan the plurality of frequencies from the most frequently used frequency to the least frequently used frequency, as defined by an administrator of the headend server 102. It should be understood by those of ordinary skill in the arts that this is merely one example and that other orders for scanning the plurality of frequencies are further contemplated in accordance with aspects of the present disclosure.
In some embodiments, after locating the IMB message, the DTA/CPEs 104.1 through 104.n may analyze the filter message 130 to determine which locator message 140 to further analyze. In some embodiments, a first value of the filter message 130 may instruct DTA/CPEs of a given manufacturer and model to analyze a first locator message, a second value of the filter message 130 may instruct the DTA/CPEs of a different manufacturer and/or different model to analyze a second locator message, and so on and so forth. In response to determining which locator message 140 to further analyze, the DTA/CPEs 104.1 through 104.n may analyze the identified locator message 140 to identify the second frequency for downloading the operating data and/or the updated operating data. In some embodiments, the locator message may be include an 8-bit message instructing the DTA/CPEs 104.1 through 104.n which frequency from among the plurality of frequencies to download the operating data and/or updated operating data.
In some embodiments, the DTA/CPEs 104.1 through 104.n may include a tuner, e.g., a QAM tuner, used to tune the DTA/CPEs 104.1 through 104.n to the second frequency. After tuning to the second frequency, the DTA/CPEs 104.1 through 104.n may download the operating data and/or updated operating data from the headend server 102 and install the downloaded operating data and/or updated operating data. In some embodiments, the operating data and/or updated operating data may include provisioning data that enables the DTA/CPEs 104.1 through 104.n to provide the requested service to the user. For example, the provisioning data may include entitlements, licenses for decrypting content, service package level subscription data, a current time for the DTA/CPEs 104.1 through 104.n, a current time zone for the DTA/CPEs 104.1 through 104.n, a zip code for the DTA/CPEs 104.1 through 104.n, and a channel lineup for the DTA/CPEs 104.1 through 104.n. It should be understood by those of ordinary skill in the art that there are merely examples of the types of information included in the provisioning data and that other types of information are further contemplated in accordance with aspects of the present disclosure. In some embodiments, after downloading the operating data and/or updated operating data from the headend server 102, the DTA/CPEs 104.1 through 104.n may tune back to the active frequency.
In some embodiments, the DTA/CPEs 104.1 through 104.n may be configured periodically download the updated operating data from the headend server 102. For example, after the initial installation of the operating data, the DTA/CPEs 104.1 through 104.n may be configured to tune back to the second frequency at predefined intervals, e.g., every two days, to download updated operating data. For example, the updated operating data may include renewed entitlements and licenses for decrypting the content. In some embodiments, after downloading the updated operating data from the headend server 102, the DTA/CPEs 104.1 through 104.n may tune back to the active frequency.
In some embodiments, after the operating data has been installed on the DTA/CPEs 104.1 through 104.n, a user may request new services from the cable provider, such as new channel subscriptions and/or on-demand content. In such scenarios, the headend server 102 may be configured to transmit the updated operating data to the DTA/CPEs 104.1 through 104.n and notify the specific DTA/CPE of the transmission of the updated data transmission. To achieve this, the filter message 130 may include information indicating which specific DTA/CPE is being targeted based on, for example, a serial number of the subscriber device. In some embodiments, the DTA/CPEs 104.1 through 104.n may be directed back to the second frequency or a different frequency to download the updated operating data. In some embodiments, the headend server 102 may begin to transmit the updated content prior to notifying the specific DTA/CPE of the update, such that the content is immediately available to the specific DTA/CPE when it tunes to the second frequency.
In some embodiments, the DTA/CPEs 104.1 through 104.n may be disconnected from the headend server 102 for an extended period of time, e.g., during travel periods or during an “off-season” at vacation destinations, such that the active channel for the DTA/CPEs 104.1 through 104.n may have changed from the last time the DTA/CPEs 104.1 through 104.n tuned to the active channel. In such instances, the DTA/CPEs 104.1 through 104.n may be configured to relocate the IMB as though the DTA/CPEs 104.1 through 104.n was being installed for the first time.
In some embodiments, the DTA/CPEs 104.1 through 104.n may be grouped based on a geographic region. This may be implemented to minimize traffic on any given frequency, such that the operating data and/or updated operating data may be transmitted as fast as possible to each geographic region. For example, each geographic region may include up to 100,000 subscriber devices 104.1 through 104.n. Assuming that that each of the 100,000 subscriber devices 104.1 through 104.n is a DTA/CPE, the headend server 102 may transmit the operating data to the subscriber devices 104.1 through 104.n in approximately one minute. However, in some geographic regions, the subscriber devices 104.1 through 104.n may include both DTA/CPEs and set-top-boxes, and as such, the operating data for the DTA/CPEs may be transmitted in less than one minute, e.g., 10 seconds. That is, when the number of DTA/CPEs is less than a total number of subscriber devices 104.1 through 104.n in the geographic region, the operating data may be transmitted at a faster transmission rate, as should be understood by those of ordinary skill in the arts. For example, in some embodiments, the operating data and/or updated operating data may be transmitted at a rate between 6 and 7 megabytes per second (MB/s).
Various aspects of the disclosure may be implemented by software, firmware, hardware, or a combination thereof.
Computer system 400 includes one or more processors, such as processor 404. Processor 404 may comprise suitable logic, circuitry, dedicated circuits, and/or code that may enable processing data and/or controlling operations of computer system 400.
