A cable converter box or television converter box is an electronic tuning device that transposes/converts channels from a cable television service to an analog RF signal on a single channel, usually VHF channel 3 or 4, or to a different output for digital televisions such as HDMI.
All digital-to-analog converter boxes have both an antenna input (which accepts the coaxial cable that formerly went directly to the TV) and an RF output (which now goes directly to the TV).
Electrical RF is directly connected to a TV or set-top box. 1550 nm is more popular because it has less losses in the fiber and by using fiber-optic amplifier known as EDFA it is possible to extend the transport distance. 1310 nm loses about 0.35 dB/km of optical signal, 1550 nm loses only 0.25 dB/km. Optical budget between transmitter and ...
Channels D1-D8 are commonly used for "LAN" links, between set-top boxes and the router. [20] E band channels are commonly used by DirecTV converter boxes. The DirecTV Ethernet-to-Coax Adapter (DECA) uses MoCA on this "Mid-RF" frequency band. D10A 100 MHz wide means it goes up to 1675 MHz, so splitters need to be 5-1675 MHz.
Assuming the dielectric properties of the material inside the cable do not vary appreciably over the operating range of the cable, the characteristic impedance is frequency independent above about five times the shield cutoff frequency. For typical coaxial cables, the shield cutoff frequency is 600 Hz (for RG-6A) to 2,000 Hz (for RG-58C). [10]
Most cable companies require a set-top box (cable converter box) or a slot on one's TV set for conditional access module cards [2] to view their cable channels, even on newer televisions with digital cable QAM tuners, because most digital cable channels are now encrypted, or scrambled, to reduce cable service theft. A cable from the jack in the ...
The delay enabled distribution of more coupons for purchase of converter boxes. [9] As of June 12, 2009, TVs and other equipment with legacy NTSC tuners are unable to receive over-the-air broadcasts from United States TV stations, unless the broadcast is from a repeater or low-power transmitter. However, Class-A stations shut down analog ...
As expressed by the minimum acceptable received signal strength indication (RSSI) for the client device, maximum range via Wi-Fi over coax varies based on transmit power of the access point radio chain, the wireless LAN (WLAN) frequency or frequencies being transmitted, the type and length of the cabling run, assembly loss caused by the ...
