BROADCASTING

Broadcasting is the distribution of audio and video content to a dispersed audience via any audio or visual mass communications medium, but usually one using electromagnetic radiation (radio waves). The receiving parties may include the general public or a relatively large subset thereof. Broadcasting has been used for purposes of private recreation, non-commercial exchange of messages, experimentation, self-training, and emergency communication such as amateur (ham) radio and amateur television (ATV) in addition to commercial purposes like popular radio or TV stations with advertisements. Broadcasting can be classified into the following:

A) Radio Broadcasting: Radio broadcasting is a one-way wireless transmission over radio waves intended to reach a wide audience. Stations can be linked in radio networks to broadcast a common radio format, either in broadcast syndication or simulcast or both. Audio broadcasting also can be done via cable radio, local wire television networks, satellite radio, and internet radio via streaming media on the Internet.

 

Advantages of Radio Broadcasting

1. A universal medium: Can be enjoyed at home, at work, and while driving. Most people listen to the radio at one time or another during the day.
2. Permits you to create a personality for your business using only sounds and voices.
3. Free creative help is usually available.
4. Least inflated medium. During the past ten years, radio rates have gone up less than other media.

 

Disadvantages of Radio Broadcasting

1. Because radio listeners are spread over many stations, to totally saturate your market you have to advertise simultaneously on many stations.
2. Listeners cannot refer back to your adverts to go over important points.
3. Radio is a background medium. Most listeners are doing something else while listening, which means your advertiser has to work hard to be listened to and understood.
4. Not as fast as using a phone; could take a little bit of time.
5. The line could get fuzzy, or not clear.

 

 

B) Satellite Television: Satellite television is television programming delivered by the means of communications satellite and received by an outdoor antenna, usually a parabolic reflector generally referred to as a satellite dish, and as far as household usage is concerned, a satellite receiver either in the form of an external set-top box or a satellite tuner module built into a TV set. Satellite TV tuners are also available as a card or a USB peripheral to be attached to a personal computer. In many areas of the world satellite television provides a wide range of channels and services, often to areas that are not serviced by terrestrial or cable providers.

 

Advantages of Satellite TV

1. High-quality audio and picture display: Satellite TV transmits highquality digital data with the use of MPEG-2 or MPEG-4 compression. MPEG-4 is also known for providing high-definition video streams to computers, cellular phones and PDAs or personal digital assistants. Think crisp and clear and you have Satellite TV.
2. Access to hundreds of channels worldwide: Satellite TV providers obtain their line-up of shows from both turnaround channels like HBO, CHANNELS TV, NTA, AIT, TVC NEWS, ESPN and CNN as well as from numerous local channels like ABC, CBS, Fox, NBC and PBS.
3. The ability to receive and send broadcast signals: Using satellite technology increases the possibilities of gaining access to channels from other countries that utilize similar technology for broadcasting. So you are not restricted to the channels on cable networks.
4. Choice of programs: A number of unique channel packages are there for the choosing by satellite TV subscribers. You can discard the channels you don’t want and select the ones you do.
5. Wider geographical coverage: Because of the wider reach of satellite technology, Satellite TV is readily available in far flung areas where cable operators cannot reach.
6. Parental lock-out options: It takes the worry out of parents concerned at what their kids are watching while they are out. Most Satellite TV receivers are now able to block certain channels from a television set.
7. WebTV option: Because Internet data can also be transmitted wirelessly, your Satellite TV can also receive Internet service from your TV set. Satellite TV is the answer if you are looking for an integrated television and internet set up. Satellite TV providers can easily hook the same TV to the Internet at an impressive connection speed for a reasonable price.
8. Digital video recorders: With some satellite TV receivers, you can record shows directly to a hard drive for play back later.

 

 

Disadvantages of Satellite TV

1. High Initial investment: The receiver and satellite dish can be expensive. Be sure to compare prices and sources before making a purchase.
2. Multiple TV sets require multiple receivers: A separate receiver for each TV is needed, making it very expensive if you have, as most have more than one TV in their homes.
3. Malfunction in bad weather: Since the satellite dish is usually located outdoors, it becomes susceptible to malfunction as a result of weather conditions like snow, very strong winds and lightning. Ensuring you get a quality product at the outset will help prevent this.
4. Require Technical Support during Installation: While one can try installing the Satellite TV equipment by himself, a competent member of the provider’s technical support team can do the job quickly with very little room for error but at an additional service fee.
