How Does DIRECTV Satellite TV Work?

DIRECTV satellites are placed into a geosynchronous orbit about 37,000 km (22,300 miles) above the earth and always remain above the same point on the earth's surface so that all DIRECTV dishes on the earth can be pointed at a fixed satellite location.

DIRECTV shows, movies, music, etc. are broadcast from an "uplink center" where programming from cable television networks and local programming from broadcast networks is collected and encrypted so that the programming cannot be intercepted by non-paying users. The uplink facility uses a dish that is 9 to 12 meters wide to accurately send a high-strength signal to the orbiting DIRECTV satellite.

The DIRECTV satellite converts the signal to a different microwave frequency band to ensure that the downlink to a subscriber's dish is not affected by uplink interference.

After traveling more than 50,000 miles, the DIRECTV signal reaches your dish on the outside of your home, office, or facility. The signal received is focussed by a bowl-shaped parabolic dish onto a device in the center of the dish called a "feed horn", which channels the signal to a "low-noise block downconverter" (LNB) which filters out unwanted interference, and sometimes converts it to another frequency before amplifying it and sending it to the satellite receiver box located inside your house, office, or facility through a coaxial cable.

A DIRECTV satellite receiver box converts the signal to television, audio, and/or data signals and may be may be equipped to decrypt the coded signal itself. You may be supplied with a "smart card" as well to decode the signal.

DIRECTV receivers also include integrated digital video recorders (DVRs) that allow you to rewind and pause live television and to record and store shows on a built-in hard drive. In addition, DIRECTV receivers offer high-definition television (HDTV), pay-per-view events and movies, interactive television channels, and video-on-demand (VOD) channels.

 DS3 Service in the Los Angeles Market

Written by: Patrick Oborn - Sep 7, 2008

Searching for a DS1 in Los Angeles? Bandwidth has never been cheaper and Los Angeles is no exception to this. Many telecom companies built out their infrastructure in Metro cities and with the crash that has taken place since 1999 many of these companies have seen the usage of their pipes decrease significantly. The infrastructure that was laid is a fixed cost that companies are eager to recover. The result of the reduced number of businesses in the market seeking service and the drop in pricing has created a buyers market.

In a buyers market remember that you can push and probably get concessions from the carrier but also remember that all carriers are not created equally. Many carriers may appear to offer a bargain price but you may be several hops from the internet and have a problem with latency. You may also be using a small carrier that hasn't actually checked the capacity of the CO before you sign your contract and can't even deliver the service they promised. The only way you'll discover this is when you start using your connection and find that at peak traffic times your connection is bogged down at a level below that which was guaranteed.

We suggest when dealing with a larger pipe you consider the larger Tier1 providers. You can still get a great price even though it's not as low as some of the Tier 1 and Tier 3 companies. You'll also have the peace of mind knowing that you have an SLA and the company will deliver what you believe you will get. If you're in the market of a DS3, communications are vital to your company. Make sure you get both a reliable product and the price you're looking for. If you need help finding such a service, consider speaking with the professionals at T1.
