Direct Satellite TV

Direct Satellite TV

What is direct satellite TV? This is satellite broadcasting you can achieve through the use of satellite dishes. Before satellite television became popular in the market during the early 1990's, satellite dishes were costly metal equipments that occupy a large space of the home yard. In early times, those die hard TV fanatics would endure all these hassles and avail these expensive equipments just to set up their own dish. Satellite TV was far more complex to obtain than regular broadcast and cable TV in the earlier days.

Nowadays, most household in the US have compact satellite dishes rested on their rooftops. We could also notice that most of the rustic areas that can't be reached by cable companies have satellite dishes. Many satellite TV companies are enticing more customers every single day with movies, game events, and daily news from all over the world which guarantees high quality picture and audio.

Satellite TV provides a lot of solutions to cable and regular broadcast TV dilemmas. With the continuous development of satellite TV, it is becoming the popular option of numerous TV viewers.

Satellite TV is not like the usual TV broadcast. It’s using a wireless system to hand over tv programming straight to a consumer's home. Both satellite and broadcast stations transport programming through radio signal.

Broadcast stations utilize a strong antenna to transport radio waves into the surrounding field. Consumers can obtain the signal through a smaller antenna. The primary boundary of TV broadcast is range. Radio signals that are employed for TV broadcast beam a straight line from the broadcast antenna. To be able to pick up this signal, you must be in the scope of the beamed signal of the antenna. Little obstructions such as trees or low buildings are fine but huge obstructions such as land mass will mirror the radio waves.

If the land mass is flat then you would receive the TV broadcast even if its miles far from the source. But due to the shape of the land mass of the Earth the signal breaks out. Another problem that occurs with TV broadcast is it the signal becomes distorted. If you want to have a clear signal like what you can have with cable tv then you must be situated pretty near the broadcast antenna and there must not be any obstructions in sight.

What did satellite TV came up with to solve these problems about range and distortion? The problem is solved through transporting broadcast signals coming from satellites revolving around the planet. Because the satellites are high above the sky, then a lot of viewers are in the scope of the signal. Satellite TV systems transport and picks up radio signals with the use of specialized antennas known as satellite dishes.

When you avail of a satellite tv, you are on your way to viewing TV programs with much clarity and gives out 100% digital-quality broadcast and audio on each channel. Don’t be fooled by so called digital cables because they still broadcast analog channels.

Digital Satellite TV

Digital Satellite TV

In many ways, digital satellite TV is similar to traditional television broadcasts in that its content is transmitted through the airwaves and captured by an antenna (in the case of traditional TV) or satellite dish (in the case of digital satellite TV). Also, the types of content that can be broadcast by both systems are analog and digital.

Unlike traditional television, however, digital satellite TV is able to deliver digital broadcasts at more practical prices because of its significant coverage advantage. This advantage is brought about by the fact that in the satellite broadcasting the content is positioned thousands of kilometers above the ground (unlike the radio transmission towers used in traditional television which are, at best, just hundreds of meters above the ground), which translates to a much wider “footprint” and economies of scale that is applied to its pricing consideration.

Digital satellite TV compresses and encrypts the digital signals of the information prior to broadcast. These broadcasts are transmitted from satellite ground stations to the satellites, which are, in turn, “blindly” transmitted by the satellite to all areas within its “footprint”. These compressed and encrypted signals are received by satellite dishes that are installed at the households and, depending on the authorizations given based on the subscriptions availed of, get decompressed, decrypted, and displayed by the digital satellite TV set-top boxes that are connected to the television sets.

Compared to an erstwhile entertainment favorite, Cable TV, digital satellite TV has the following advantages:

PracticalityDigital satellite TV’s main advantage over Cable TV is that it costs less to maintain the service because there are only four points of failure; i.e., the ground station, the satellite, the satellite dish, and the television itself. In Cable TV, there are several kilometers of cable that need to be checked when a particular subscriber loses his service, aside from trouble at the cable TV headend, other distribution points, and the television set. This advantage allows digital satellite TV service providers to charge less for digital content than cable TV providers.
Wider CoverageAmong the three broadcast media (digital satellite TV, traditional television broadcast, and Cable TV), Cable TV has the smallest coverage reach. This means that the addressable market is also the smallest for Cable TV, which limits the number of subscribers it can provide service to. In contrast, digital satellite TV only has one requirement, i.e., the area it will serve has a direct line of sight to the satellite. All a subscriber needs to purchase is a satellite-band compatible satellite dish, a provider-issued set-top box and a subscription plan with the digital satellite TV provider to enjoy the service.

There are several digital satellite TV providers that a potential subscriber may avail of. Among these are VOOM, DirecTV and DISH Network. These providers offer service packages that include high-definition TV channels and information aside from the standard packages that cable TV companies provide. All these without hurting your pocket any more than it would if you continued with your Cable TV service.

Broadband Internet TV

Broadband Internet TV

With the growing proliferation of broadband Internet in every household, it is a natural phenomenon for services that have traditionally been delivered via analog means to be alternatively delivered via Internet Protocol (IP). One of these services is the broadcast of television programs via broadband Internet instead of radio waves. This is called Broadband Internet TV.

The major advantages of broadband Internet TV are:

Broadcasters can reach a wider audience without having to worry about the additional cost needed, since the viewer pays for the broadband access. This translates to a bigger opportunity to generate more income from advertising.
The viewer need not be at home to be able to watch his favorite TV shows since all he will need is Internet access. Again, because the Internet is so pervasive, it now becomes possible to be anywhere in the world and still be up-to-date with the latest news, sitcoms and other TV shows that you would normally watch at home. This brings rise to the opportunity for broadcasters (assuming that their business model does not rely mostly on advertising revenues) to charge subscriptions for remote access to their shows. Using encryption, data for shows
The viewer can be selective as to the shows he/she wants or allows his children to watch. Filters can be applied to block or limit access to certain shows.

There are, of course, disadvantages to broadband Internet TV. For example, to be able to access broadband Internet TV, of course, assumes that there you have access to broadband Internet with speeds of at least 256kbps. This is a relatively slower speed than that which was required a few years ago when 512kbps was the minimum broadband speed was needed. Better compression technology makes streaming video at lower speeds possible. Nevertheless, broadband access is still a requirement.

Another disadvantage of broadband Internet TV is that it requires that you either have a computer with the appropriate decoding software, or a set-top box with decoding software. The latter is needed if you want to use your television set as the display medium.

Also the broadband Internet TV output resolution is currently inferior to that of radio broadcast technology. This is because higher resolution requires more file storage space that translates to more bandwidth to get a real-time streaming video experience. Also, the bigger the image, the finer the resolution needs to be so that it does not “break up” during display. Again, this translates to bigger file sizes and bigger bandwidth requirements.

Broadband Internet TV is offered in two modes: Free and Subscription Based. The Free mode is the akin to the conventional “free-to-air” television programming, where all you need to have is a television set configured to the broadcast system in your area (e.g., NTSC, PAL/SECAM, etc.), a television antenna to capture the broadcast, and electricity. Subscription mode is similar to the model of cable TV, where a monthly fee is paid for a set of channels, with extra charges levied for premium channels on a pay-per-view or monthly basis.

Stream Video from pc to TV

Stream Video from pc to TV

Most of us are TV fanatics that if we have free time, we’ll find ourselves in front of the television. And I’m one of those so called “TV addicts”. I’m very interested in all the software and hardware that appear in the market that offer great access to more channels. I search the Internet. I was amazed that many people are also searching on how to enjoy their TV watching to the highest level.

While browsing Net, there are various topics about having TV on your PC and watching TV online. Are these not interesting topics to read about? Actually, these are pretty much interesting topics. Why? Well, you don’t need to call companies that offer cable or satellite TV to have a wide range of channels. Such topics are helpful for it give you more information on how you can stream video from PC to TV. While learning the information related to such topic, all you need is a PCTV tuner and fast internet connection.

Suddenly, it crosses my mind that I want to watch those videos not on my PC but on our TV. So how I’m going to do it? I search on “streaming videos from PC to TV”. My first impression is that it will not be as easy as I thought it would be. I continue researching more, reading forums and such. Also, another option is the U-Broadcast. I searched for it and found that it is a product of Uticasoft. It is a webcam viewer, TV tuner viewer, video capturer and live- stream server.
There are many choices that came my way. And it’s really hard to decide. I also read the comments of other people about certain software or hardware to be able to stream videos in the most convenient way. Some successfully got what they want but then a flaw will be encountered. Then they will try other ways to stream videos. It consumes time and effort and money as well but it’s worth it in the end.

As I continue my search, I’ll find more methods, specific ones that I can share with other TV addicts out there. I will ask for other people’s advices on this matter. I will continue reading forums and blogs that will help me to have what I want. It’s not only the thought of me able to stream videos but knowing how it’s done and me able to share it, gives others the chance to also enjoy the benefits of video streaming. Some people don’t have enough time like me to search the internet just to get information.

So I’ll pick one and I will try it. If it works, I will tell you as soon as possible. If I failed, I will still write about it but ask other people what maybe went wrong. Then I will try another one. I know that companies are dealing with this demand intensely so I’m not alone. Maybe tomorrow or the next day, video streaming will be as easy as no one as of this moment expect it to be. Then, my first impression will not last anymore.
