Description
- This patent application is a continuation of U.S. patent application Ser. No. 15/138,902, filed Apr. 26, 2016, which is a continuation of U.S. patent application Ser. No. 14/256,355, filed Apr. 18, 2014, which is a continuation of U.S. patent application Ser. No. 14/080,418, filed Nov. 14, 2013, which is a continuation of U.S. patent application Ser. No. 13/687,742, filed Nov. 28, 2012, which in turn makes reference to, claims priority to, and claims benefit from U.S. Provisional Application Ser. No. 61/595,654, filed Feb. 6, 2012.
- This patent application also makes reference to:
- U.S. patent application Ser. No. 13/326,125 filed on Dec. 14, 2011;
U.S. patent application Ser. No. 13/596,852 filed Aug. 28, 2012;
U.S. patent application Ser. No. 13/715,250 filed Dec. 14, 2012;
U.S. patent application Ser. No. 13/687,626 filed Nov. 28, 2012; and
U.S. patent application Ser. No. 13/687,676 filed Nov. 28, 2012. - Each of the above stated applications is hereby incorporated herein by reference in its entirety.
- Certain embodiments of the invention relate to communication systems. More specifically, certain embodiments of the invention relate to a method and system for an Internet protocol LNB supporting positioning.
- A satellite television system may comprise a low noise block downconverter (LNB), which is generally co-located with a satellite dish in the satellite television system. The conventional LNB may be operable to amplify a received radio frequency (RF) satellite signal and convert such signal to lower frequencies such as, for example, intermediate frequencies (IF). Presently, satellite television systems have become ubiquitous, primarily due to reductions in the cost of satellite television reception technology. A plurality of satellite television systems may be in a neighborhood.
- Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with the present invention as set forth in the remainder of the present application with reference to the drawings.
- A system and/or method for an Internet protocol LNB supporting positioning, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
- Various advantages, aspects and novel features of the present invention, as well as details of an illustrated embodiment thereof, will be more fully understood from the following description and drawings.
-
FIG. 1 is a block diagram illustrating an exemplary communication system, in accordance with an embodiment of the invention. -
FIG. 2 is a block diagram illustrating an exemplary satellite television system, in accordance with an embodiment of the invention. -
FIG. 3 is a block diagram illustrating an exemplary Internet protocol LNB assembly, in accordance with an embodiment of the invention. -
FIG. 4 is a block diagram illustrating an exemplary scenario of an Internet protocol LNB assembly providing location service, in accordance with an embodiment of the invention. -
FIG. 5 is a block diagram illustrating an exemplary scenario of an Internet protocol LNB assembly performing digital rights management and/or conditional access, in accordance with an embodiment of the invention. -
FIG. 6 is a block diagram illustrating an exemplary scenario of an Internet protocol LNB assembly detecting relocation, in accordance with an embodiment of the invention. -
FIG. 7 is a block diagram illustrating an exemplary scenario of an Internet protocol LNB assembly determining location information, in accordance with an embodiment of the invention. -
FIG. 8 is a flow chart illustrating exemplary steps for an Internet protocol LNB assembly supporting positioning, in accordance with an embodiment of the invention. - As utilized herein, “and/or” means any one or more of the items in the list joined by “and/or”. As an example, “x and/or y” means any element of the three-element set {(x), (y), (x, y)}. As another example, “x, y, and/or z” means any element of the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), (x, y, z)}. Certain embodiments of the invention can be found in a method and system for an Internet protocol LNB supporting positioning. In various embodiments of the invention, an Internet protocol low noise block downconverter (IP LNB) assembly, which is within a satellite reception assembly, may be operable to determine location information and/or time information of the IP LNB assembly. The IP LNB assembly may be operable to provide services based on the determined location information and/or the determined time information of the IP LNB assembly. In this regard, the IP LNB assembly may determine the location information and/or the time information of the IP LNB assembly via, for example, a global navigation satellite system (GNSS) module in the IP LNB assembly.
- In an exemplary embodiment of the invention, the IP LNB assembly may be operable to communicate the determined location information and/or the determined time information to a wireless communication device, which may be communicatively coupled to the IP LNB assembly. In such instances, the wireless communication device may determine location information of the wireless communication device, based on the location information and the time information communicated from the IP LNB assembly and other location information and corresponding other time information communicated from one or more other IP LNB assemblies. In this regard, the wireless communication device may also be communicatively coupled to the one or more other IP LNB assemblies. The IP LNB assembly may be operable to receive the location information of the wireless communication device from the wireless communication device. The received location information of the wireless communication device may then be stored in the IP LNB assembly, for example.
- In an exemplary embodiment of the invention, the IP LNB assembly may be operable to perform digital rights management (DRM) and/or conditional access (CA) for content delivery based on the determined location information of the IP LNB assembly. The determined time information of the IP LNB assembly may be communicated, by the IP LNB assembly, to one or more other IP LNB assemblies in a region for accurate timing recovery for the region. Based on the determined location information of the IP LNB assembly along with other location information associated with other IP LNB assemblies in a region, a location map may be generated by the IP LNB assembly for the region. Based on the determined location information of the IP LNB assembly, relocation of the satellite reception assembly and/or an associated gateway may be detected by the IP LNB assembly.
- In an exemplary embodiment of the invention, the IP LNB assembly may be operable to determine location information of a wireless source device based on the determined location information and the determined time information of the IP LNB assembly along with a plurality of other location information and a plurality of corresponding other time information associated with a plurality of other IP LNB assemblies. In this regard, the plurality of other IP LNB assemblies may be communicatively coupled to the IP LNB assembly. The time information and each of the other time information may be determined based on receiving a corresponding signal from the wireless source device. The IP LNB assembly may determine the location information of the wireless source device locally and/or remotely via a location server, for example. The determined location information of the wireless source device along with other characteristics of the wireless source device may be stored in a database in the IP LNB assembly, for example. A third party may utilize the determined location information in real-time or at some later time (e.g. via a log), in order to verify the position or location of the wireless source device.
