For those who are interested in techies, here are some interesting details about internet television via satellite. Communication
via satellite is possible because the satellite is fixed onto an orbit at a distance of 37,500 km above the equator approximately) and it will stick to this position wherever transmission is performed. This aspect will allow the satellite antenna two ways that emits and receives signals to align on the wave (spot) of the satellite and to stick to a fixed position.
Through broadcast via radio, those who handle satellite programming transmit signals to a proper satellite owned by a space channel. Often signals which are emitted or received do not reach the destination without being interrupted or disturbed, in order to prevent unauthorized reception of signals before re-transmitting them to a satellite antenna based on the ground. The signals transmitted are received by a transponder, which can be found even on the satellite, a device that receives signals and sends them back to Earth after it switches them to a frequency, which can be received by a satellite antenna fixed at the ground level. There are usually 24 to 32 transponder systems on each satellite.
On the purpose to reduce to minimum the interference between transponder systems, signals are transmitted alternatively through some polarized antennas. Each satellite occupies a fixed position, which is well determined on the orbit and it functions on a specific frequency distributed by FCC. You can find more details in this matter if you access a specific site and ask experts to explain you what you do not understand.
On the contrary, one of the primary reasons why Internet TV is not the preferred choice of viewers across the world is lack of cheap and fast bandwidth. Even though Net access is increasingly becoming affordable and speeds have zoomed though the roof, watching streaming media over the net is still has room for growth.
The Real Drawbacks of Internet TV
To be fair, there are a lot of other factors that still have room for growth. To begin, streaming technology itself is in its infancy. Output has less than desirable quality, resolutions are still pretty poor and the technology itself requires a shake-up, much like Microsoft did for the PC industry. What this industry requires is free, scalable technology which supports high-quality streaming media on low bandwidth. It should also be able to provide free codecs to all viewers, bar none, so that they can watch the shows and the streaming content of their choice over the Web.
Some Solutions for Streaming Media on the Web
In the short-term, several remedies have been proposed. For example, many companies have begun to stream existing TV shows on the Internet. Some others broadcast pay shows either free of cost on their sites or for lesser pay. Such companies often keep some control over how such pay-per-view shows are broadcast due to reasons like copyright protection, revenue, etc. Moreover, some have hot upon a real goldmine and they develop unique content for the Web, which is not available elsewhere.
