He Previously, cable TV is the technology of choice for television programming. This was true even with the availability of satellite TV, satellite TV, but at the time was too expensive for most people to afford, and even those who could afford it still had to deal with massive satellite dishes that technology of the time required.

In the first half of the nineteen nineties, the situation has changed with the introduction of digital television by satellite, which provided a much needed further improvement to both the satellite TV that came before him and cable TV. This new wave of technology of satellite television required only a small satellite dish that was three feet wide at most, rather than the monstrosities that were aged more than ten feet in diameter. At the same time, new technology has enabled satellite technology to offer more channels at reasonable prices.

The exodus of viewers leaving the cable TV for satellite TV has started because of the realization that spending the same amount of money on satellite TV they had paid for cable TV could provide viewers with a much greater choice of channels. The fact that satellite dishes were much smaller and therefore more manageable also made a huge difference when it comes to satellite TV a viable alternative for commuters who do not have room for more dishes . The cable company makes its own situation worse by rejecting the additional channels as a quality inferior to that provided by cable television and thus not interesting for viewers. What the cable industry has not taken into account was that viewers like having more choices and if they could spend the same amount of money their subscription television cable cost about a service that offers about three times the number of channels, all of these extra channels were essentially free. In short, there is the television industry supported by cable or not the extra channels offered by satellite TV industry has been good because they were essentially free.

Now the industry is finally cable television implementation of technologies that could reverse the situation in the other direction. This technology is called switched digital video. Switched digital video essentially increases the number of separate channels that a cable TV provider may offer a better use of bandwidth by existing cable television. Currently providers of cable television and simply send all their channels at once to all their subscribers. The digital receivers of subscribers, and filter these channels. Strings that are not part of the subscription are filtered first, then all the channels that the subscriber does not want to look at a particular time are filtered. This means that even if the cable television company can transmit hundreds of channels on cable and making the most if not all, of the bandwidth of the cable-only is given every viewer watching one of these channels at once . Switched digital video allows the cable company to offer all the channel that the viewer wants to see at some point. This means that the company can provide a virtually unlimited number of channels.

Switched digital video may be just the technology that industry has to offer cable TV customers to return the satellite TV.
