Digital and Analog TV Essay

On February 17, 2009, the Congress of the United States mandates the sound shift to digital telecasting contagious disease. The law is perceived to bring some(prenominal) welfares to the US viewing public. Broadcast frequency bands will be getable mainly for public safety purposes, for example, police and fire department concerns. rest portions of the old TV dole out spectrum mass be offered for technologically advanced applications such(prenominal) as wireless broadband.The use of digital-capable television sets allows American attestants more(prenominal) choices of what programs to watch, since digital broadcasts can accommodate so much more programs (Federal Communications Commission, 2008). The law is not expected to be received openly by the television viewing public, 100 percent. Since it leaves them no choice solely to convert millions of TV sets from linear to digital and give up the original fidelity that analog audio signals offer. This paper aims to point out the differences of digital and analog TV.By doing so, advantages and disadvantages of each can be compared and the individual viewer can make a better choice. Robert Silva (2008) lists differences between analog TV and Digital TV. He says these these differences lie mainly in the port of transmitting broadcasts, signal content within a bandwidth in the broadcast spectrum, and the ability to broadcast in panoptic prove (169) format. Transmission Analog television contagion is based on and started after World War II with grisly and white broadcasts.It complied with the US analog TV standard known as NTSC. After several years, color broadcasting was introduced and accommodated under the NTSC system. The video is transmissible through the AM radio band while audio is ancestral through the FM band. The reception quality depends on the distance from the television station transmitters and obstacles in between. The farther away from the transmission station the TV reception is more pr one to ghosting and other video disturbances.Although analog transmission can accommodate all the technicalities of high fidelity reception, the depute bandwidth to a television channel restricts and limits broadcast quality. Digital TV is based on modern digital technology. It was designed for BW and color broadcasts as wellspring as audio. It handles information in the equal manner as computers on (with a binary value of 1) or off (with a binary value of 0). Digital broadcasts allow viewers to regulate uniform reception quality regardless of the distance from the transmitter.Either the digital television receives the broadcast or the TV screen remains lacuna (it does not receive anything at all). Signal Content Digital TV broadcasts can accommodate complete video, audio, and other information signals within the same bandwidth. Furthermore, digital television can accommodate advances in technology similar High Definition (HDTV) signals. In contrast, analog TV broadcast can on ly send limited traditional video signals. Format The teaching of wide screen format programming allows the broadcast of the 169 format.Today, widescreen LCD television are getting more popular that still expensive. It offers the advantage of portraying on the TV screen wide footages of events without the camera lens distortion caused by distances. Furthermore, the widescreen image occupies the whole digital television screen. On the other hand, analog television sets will describe widescreen images with portions on top and below blacked out. The widescreen format may not be important to the regular TV viewer. For millions of television watchers, the old analog screen is good enough.Conclusion Paul Wotel (2008) gives an objective assessment of the advantages and disadvantages of both digital and analog television. Some people may opt for the old traditional analog equipment such as phones while others prefer the cordless digital phones. If you want sound fidelity, he recommends the old phones. For more advanced applications, such as the PABX systems, he recommends a digital system. The same reasoning may be applied to television sets. However, the present situation requires new priorities which did not exist before. Today, there is much concern on security and priority is given to police and fire department communications.By requiring television place to convert to digital transmission, most of the broadcast bandwidth can be assigned to security applications. The advantages of digital television allow the viewing public to benefit from the information age we find ourselves in. Digital television can in any case take advantage of the internet which has become part of the lives of many, particularly the little generation. Considering the continuing evolution in information and entertainment technology we except have to follow the trend out with old, in with the new.
