8-Port TV Distribution Amplifier. For households with multiple TVs, the Antennas Direct 8-Port TV Distribution Amplifier can split a signal with no noticeable impact on signal quality.
In the US, multiple digital signals are combined and then transmitted from one antenna source to create over the air broadcasts. By the reverse process ( demultiplexing ), an ATSC receiver first receives the combined MPEG transport stream and then decodes it to display one of its component signals on a TV set.
The five main ATSC formats of DTV currently [when?] broadcast in the U.S. are: . Standard definition—480i, to maintain compatibility with existing NTSC sets when a digital television broadcast is converted back to an analog one [citation needed] —either by a converter box or a cable/satellite operator's proprietary equipment
Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
The main lobe of the antenna can be steered electronically within a limited angle by phase shifting the drive signals applied to the individual elements. Each antenna element is fed through a phase shifter which can be controlled digitally, delaying each signal by a successive amount. This causes the wavefronts created by the superposition of ...
