What do cable boxes do




















And best of all, it also eliminates your cable clutter. With just a few minutes of setup, you can enjoy p or even 4K HD video wirelessly. Power off your set-top or cable box and plug one end of the HDMI cable into the back of that. Make sure the green power light comes on. Next, get out the receiver, the other HDMI cable, and power adapter.

Make sure the green power light is on. There you have it! Wireless streaming TV in any room of the house without running messy wires!

The cable systems receiving the signals used dish antennas 10 meters in diameter, with a separate dish for each channel! With the beginning of satellite program delivery to cable systems, the basic architecture of the modern cable system was in place. As the number of program options grew, the bandwidth of cable systems also increased.

Early systems operated at MHz, allowing 33 channels. As technology progressed, the bandwidth increased to , , and now MHz, with the number of channels increasing to Two additional advances in technology -- fiber optics and analog-to-digital conversion -- improved features and broadcast quality while continuing to increase the number of channels available.

In , a new sort of cable system debuted. This system used fiber-optic cable for the trunk cables that carry signals from the CATV head-end to neighborhoods. The head-end is where the cable system receives programming from various sources, assigns the programming to channels and retransmits it onto cables.

By the late s, fiber optics had progressed considerably and so were a cost-effective means of carrying CATV signals over long distances. The great advantage of fiber-optic cable is that it doesn't suffer the same signal losses as coaxial cable, which eliminated the need for so many amplifiers.

In the early fiber-optic cable systems, the number of amplifiers between head-end and customer was reduced from 30 or 40 down to around six. In systems implemented since , the number of amplifiers has been further reduced, to the point that only one or two amplifiers are required for most customers. Decreasing the number of amplifiers made dramatic improvements in signal quality and system reliability. Another benefit that came from the move to fiber-optic cable was greater customization.

Since a single fiber-optic cable might serve households, it became possible to target individual neighborhoods for messages and services. In the s, cable providers found this same neighborhood grouping to be ideal for creating a local-area network and providing Internet access through cable modems. In , General Instruments demonstrated that it was possible to convert an analog cable signal to digital and transmit it in a standard 6-MHz television channel.

When combined with a MHz overall bandwidth, this allows the possibility of nearly 1, channels of video on a system. In addition, digital technology allows for error correction to ensure the quality of the received signal. By , the marriage equality movement had won in courts and legislatures—but not at the ballot box. Beside her was a box of bonbons, which she held out at intervals to Madame Ratignolle.

Now and then the boy who had bought Squinty, and who was taking him home, would look around at his pet in the slatted box. The little pig in the box felt himself being lifted out of the wagon. Newbolt was cutting splints for her new sun-bonnet out of a pasteboard box.
