Embodiments of this disclosure are directed to antennas and antenna arrays for use with digital televisions (DTVs)
A common complaint associated with antennas for use with DTVs is the occasional if not frequent need to physically rotate or otherwise manipulate an antenna so as to attempt to improve signal reception and/or receive different channels.
Embodiments of the present disclosure eliminate this complaint by providing an antenna array assembly comprising at least two antennas, which form the array, connected to a switch box or antenna switcher and controlled by the tuner of a DTV, or manually by a user directly of by remote control. The tuner includes a memory function, which will remember which antenna works best for a given signal, and automatically signal the switch box to select the appropriate antenna when a user selects a channel. As such the user is never required to physically manipulate the array or its individual antennas.
In some embodiments, the array comprises at least three antennas.
In at least one embodiment the assembly includes one or more inputs through which one or more additional antennas (such as a roof antenna) may be added to the array.
In some embodiments, the array assembly includes a housing that the array and switch box are engaged to or contained within. The housing includes an HDMI or other type of output interface for connection to the DTV tuner. In some embodiments the assembly is integrated into the housing of the DTV.
In at least one embodiment, the assembly includes a remote control input interface, such as a radio frequency (RF) or infra-red (IR) interface. In at least one embodiment remote control of the assembly is via computer or smart phone application.
In some embodiments, the assembly includes a signal strength meter for detecting and displaying the strength of a given (channel) signal being received by one or more of the individual antennas of the array.
In at least one embodiment the individual antenna that is utilized to provide a received signal to the tuner may be manually selected by the user for use from amongst other antennas within the array.
These and other embodiments are described in greater detail below and are illustrated in the following drawings.
As mentioned above, embodiments of the present disclosure are directed to an antenna array assembly 10 such as is illustrated in
The antennas collectively make up an array 20, which may include a mast 22 or any other structure capable of holding the antennas 12, 14 and 16 in a relatively fixed direction orientation. Each antenna 12, 14, 16 may be adjustably mounted on the mast 22 to allow for repositioning of the antennas relative to the mast 22. Engagement of the antennas 12, 14, 16 to the mast 22 may be may any mechanism desired such as by fasteners, adhesives, frictional engagement, etc. Likewise, the mast 22 may be adjustable relative to a base 24 to allow the entire array 20 to be repositioned as desired.
Though such adjustability of the antennas and array may be provided to the assembly 10, the inclusion of multiple antennas in forming the array 20 should make the need for such adjustability unnecessary. By providing the array 20 with a plurality of directional antennas 12, 14, 16, the array will receive a signal 30 sent from a given transmitter 32, by at least one of the individual antennas 12, 14, 16 regardless of the location of the transmitter 32. Multiple signals 30 may be received from multiple transmitters 32, but for each signal at least one antenna 12, 14, 16 will be positioned for optimal detection of a given signal. Thus, the assembly 10 eliminates the need for manual manipulation of the individual antennas 12, 14, 16 or the array 20.
In order to determine which antenna 12, 14, 16 is receiving a signal 32 more optimally that the others, the array 20 is connected to a switch box or antenna switcher 40; which in turn is configured to communicate and be controlled by the tuner 42, which in turn is configured for communication with a DTV or monitor 44. The monitor 44 is any form of visual display device with a built-in TV tuner. The assembly 10 is configured for wireless or wired connection with a TV, monitor, projector, and/or any other form of video display device including computers and related devices.
This communication path way is depicted in
An example of the switcher functionality provided by the communication between the tuner 42, switcher 40 and array 20 is illustrated by the look-up table 50 shown in
In embodiments of the assembly 10, such as are shown in
In at least one embodiment the assembly 10 includes a radio transmitter 68 for WIFI communication with a router or other device to provide wireless communication and interface with the DTV 44 or multiple DTVs, computers or other devices. In some embodiments, housing 60 also will include a receiver node or window 66 for receiving radio, infra-red, or other types of controlling signals from the remote control 46.
Should it be determined that the assembly of the types shown in
In some embodiments, an example of which is shown in
As mentioned above, in some embodiments, it may be desired to provide direct manual control of antenna selection rather than provide automatic antenna selection by optimized signal receipt as determined by the tuner 42. An embodiment depicting such a direct selection assembly 10 and its functionality is depicted in
In the embodiment shown, the assembly 10 still includes multiple antennas 12, 14, 16, and a switcher 40. But in place of a tuner the assembly is provided with a signal strength meter 80. When operational, the antenna switcher 40 would pick the antenna 12, 14, 16 of the array 20 that is receiving the most channels or the selected channel having sufficient strength to be received by a television tuner as determined by the strength meter 80. The other antennas not receiving the desired signal or sufficient number of signals would go unused. A remote control 46 would allow a user to select from between antennas 12, 14 and 16. With communication to a television 44 via a coax cable interface 82. The lower power requirements of such an assembly 10 allow the assembly to be powered by standard 5 v USB (or equivalents) type connection 85 such as may be provided by direct interface with the television 44. Other power sources may also be utilized, including direct plug in to a 100-120 v wall outlet or even by battery.
The many features and advantages of the invention are apparent from the above description. Numerous modifications and variations will readily occur to those skilled in the art. Since such modifications are possible, the invention is not to be limited to the exact construction and operation illustrated and described. Rather, the present invention should be limited only by the following claims.
