Currently, for comparison, the Spectrum cable receiver box is $10.99 per month. Yearly cost: Cable box: $132 vs Xumo: $60. Cloud DVR Pricing aside, it’s just a better service, in every way. But ...
The new box, called XUMO, replaces the old set-top cable box and has several new features.
Without single-cable distribution, providing full-spectrum access for multiple receivers, or receivers with multiple tuners, in a single-family home has required a separate coaxial cable feeding each tuner from the antenna equipment (either multiple LNBs, a multi-output LNB or a multiswitch distribution system) because of the large bandwidth ...
A standard rack-mount headend. Once a television signal is received, it must be processed. For digital satellite TV signals, a dedicated commercial satellite receiver is needed for each channel that is to be distributed by the cable system; these are usually rack-mountable receivers that are designed to take up less space than consumer receivers.
OTA antennas are digital receivers that pick up signals broadcast by local TV towers, allowing you to watch local programming without cable. These antennas cost anywhere from $15 to $50.
SFNs use the available spectrum more effectively than conventional multi-frequency broadcast networks , where program content is replicated on different carrier frequencies. SFNs also result in a diversity gain in receivers situated midway between the transmitters. The coverage area is increased and the outage probability decreased in ...
Spread spectrum generally makes use of a sequential noise-like signal structure to spread the normally narrowband information signal over a relatively wideband (radio) band of frequencies. The receiver correlates the received signals to retrieve the original information signal.
A signal sent by an ideal transmitter or received by a receiver would have all constellation points precisely at the ideal locations, however various imperfections in the implementation (such as noise, low image rejection ratio, phase noise, carrier suppression, distortion, etc.) or signal path cause the actual constellation points to deviate ...
