Lucky for us, we were able to pull a ZeeVee ZvBox in for review, and after a few setbacks during setup, we were left playing with something pretty unique. The problem of course is that unique isn ...
A Web-to-TV installation provides a way to show streaming television or other over-the-top content from the Internet, to a television set.Various technologies to do this include Home theater PCs (desktop computers running more user-friendly software for TV viewing), digital media receivers (also known as "media extenders", replaying content from a local area network), and Smart TVs (television ...
QAM is used in a variety of communications systems such as Dial-up modems and WiFi. In cable systems, a QAM tuner is linked to the cable in a manner that is equivalent to an ATSC tuner which is required to receive over-the-air (OTA) digital channels broadcast by local television stations when attached to an antenna. Most new HDTV digital ...
A modulator is a device or circuit that performs modulation. A demodulator (sometimes detector ) is a circuit that performs demodulation , the inverse of modulation. A modem (from mod ulator– dem odulator), used in bidirectional communication, can perform both operations.
VITEC's Rugged H.264 Encoders receiveMIL-STD-810F and MIL-STD461 Certifications. SUNNYVALE, Calif.--(BUSINESS WIRE)-- VITEC, a worldwide leader in advanced video solutions, today announced its ...
The demodulator, which is designed specifically for the symbol-set used by the modulator, determines the phase of the received signal and maps it back to the symbol it represents, thus recovering the original data. This requires the receiver to be able to compare the phase of the received signal to a reference signal – such a system is termed ...
Wireless HDMI is the wireless transmission of high-definition audio and video signals between devices, using unlicensed radio frequencies like 5 GHz, 60 GHz, or 190 GHz. This technology eliminates the need for an HDMI cable , allowing users to transmit signals wirelessly between the component device and the display device.
An alternate method of generation known as a Hartley modulator, named after R. V. L. Hartley, uses phasing to suppress the unwanted sideband. To generate an SSB signal with this method, two versions of the original signal are generated, mutually 90° out of phase for any single frequency within the operating bandwidth.
