Tips on Direct TV Remote Control Programming

Posted in Topics on March 16th, 2010 by admin – Be the first to comment

     If you see the Direct TV remote control, you will find that there are many buttons whose functions are difficult to grasp. The typical ones are the slide switch having four positions for easy component selection, code library for video and stereo components, code search to enable program control, and memory protection to make sure that the user would not need to re-program the remote when he changes the batteries.

     To start off with the Direct TV remote control programming, you are required to choose the equipment which is needed for programming. Generally, a majority of the remote controls have separate buttons which correspond to different equipments. ‘SAT’ operates the satellite receiver, ‘TV’ controls the television, ‘VCR’ controls the Video cassette recorder, and ‘Aux’ operates one of the various additional devices like the home stereo system. You are required to press the button of the equipment to program until the corresponding light on the remote control flashes.

     After you have decided on the device that is needed for programming, you would have to determine the appropriate code for that particular device. Codes for a majority of companies and makes can be found at the back of the remote control’s manual. read more »

     There is more than one way of getting a free satellite TV. However, the easiest way is to look out for offers provided by the two satellite TV giants U.S. Dish and U.S Direct. The things that you generally get free in a typical free satellite TV service offer includes a four television satellite system, free installation from professionals, a HDTV (high definition TV) receiver, a digital video recorder (DVR) and also a few more bonus goodies, if you are lucky. These bonus goodies may include free satellite radio and home theater systems. Some offers also include a free Internet connection, lifetime warranty and even free upgrades for certain packages. Also, some offers might give you one TV receiver while others might give you two. So, before taking advantage of any free satellite TV offers, thoroughly evaluate all other offers that are available in the market at that point of time.

     But if you are thinking how to get free satellite TV without involving the TV service providers directly, the following procedure is just what you are looking for.

     Procedure for Buying and Installing your Own Free Satellite TV System

     A large number of unencrypted free to air satellite TV channels are available today. The consumers can view these channels without paying any subscription fees to any satellite TV service provider. However to tap these channels, the consumer needs to buy the right TV receiving equipment and install it appropriately in the locality.

HDTV

     HDTV requires high-definition signals in order to broadcast superior-quality picture. The signals transmitted over the air with antennas are received by a HD tuner, which is built into modern-day television sets. A separate tuner box can be used for television sets that do not have an inbuilt HD tuner. Certain cable television companies offer HDTV transmission through set-top boxes issued by them to the TV users. Some of the satellite TV systems of today feature support for the reception and transmission of TV signals.

     An HDTV features a digital broadcasting of signals. Digital signals use patterns of 1s and 0s, which result in higher-resolution images. Also, digital images are less fuzzy and have more clarity. The transmission of digital signals results in sharper and more realistic colors and an improved picture quality. The digital compression methods used by HDTV allow the bandwidth of a single analog channel to be used by two high-definition TV channels.

     HDTV offers a frame-rate of 25-60 frames per second. It uses an interlaced scanning system in contrast with the progressive scanning system used by traditional television. Progressive scanning is a method of displaying moving images in which all the lines of each frame are drawn in a sequence. Interlaced scanning is a method of electronic display wherein each row of pixels of a moving image is scanned using two frame fields, one for odd lines of the image and the other for its even lines. Interlacing helps in the reduction of flicker, thus improving picture quality.

     There is a marked difference between the aspect ratios (the width of a picture divided by its height) of a traditional television and HDTV. High-definition television systems offer an aspect ratio of 16:9 as against 4:3 offered by traditional television. Greater aspect ratio means that HDTV comes with a wider screen and provides clearer pictures. read more »

Satellite TV vs. Cable TV

     Satellite television is subject to quite a few myths. Viewing via satellite is reliable and unlike the bygone era, rain and gales do not affect presentation. The technology has advanced with time and is very effective in delivering entertainment at the click of a button. Channel variety, programming and dedicated networking is also a part of the Satellite TV package. The service is provided by dedicated online and offline service providers, who also educate clients on the stability enhancing techniques and practices. Satellite TV is cheap and comes along with high definition content. The latest technological enhancements of Satellite TV include the ability to record and store entertainment for as long as desired. The investment is a one-time bargain, with the only add-ons coming in with subsequent upgradation and the electricity bill. Installation of Satellite TV is usually a free service and even if charged in some cases, the rates are very reasonable. Satellite television is also marketed as part of company package deals, where certain household appliances are offered free-of-cost with the purchase.

Satellite Dish Antenna

Posted in Theory on March 16th, 2010 by admin – Be the first to comment

     Before we talk about the installation of of a satellite antenna, let us understand its working. The parabolic shape of a dish antenna is designed to capture incoming satellite signals (electromagnetic waves) and focus it to a central focal point, where it is concentrated and fed to a ‘feedhorn’. This feedhorn is a waveguide (a device that directs electromagnetic waves) shaped in the form of a cylindrical structure usually, and positioned at or near the focal point of parabolic dish antenna with the use of brackets. This waveguide directs the incoming signal to a LNB (Low Noise Block Down Converter), which is an transducer that converts electromagnetic waves into electric signals. It also shifts the frequency from the frequency of C-band (500 MHz – 1000 MHz) or Ku band (12GHz – 18 GHz) to the L-band (1 GHz – 2 GHz) frequencies.

     In most home use satellite dishes, the feedhorn and the LNB are integrated into one device called LNBF. The gain or power of signal received is dependent on the perfection of the dish shaping and the waveguide matching. Normal home use parabolic antennas are around 43 cm – 80 cm in diameter and are positioned for reception of incoming Ku Band reception. Read more on how does satellite dish work.

     Satellite Dish Antenna Installation
     With that introduction to the working of a satellite dish antenna, let us now have a look at the procedure for satellite dish installation. First part of installation is of course gathering the required equipment and tools for installation.

     There are two main parts of satellite dish installation. First is fixing the mast of the dish antenna and second is fixing the dish on the mast and orienting it in the exact direction to get the maximum signal strength. The rest of the part is just connecting your dish antenna to your TV, using a coaxial cable. read more »
