Digital and Analog TV Essay Example for Free

Digital and Analog TV Essay On February 17, 2009, the Congress of the United States mandates the full shift to digital television transmission. The law is perceived to bring several benefits to the US viewing public. Broadcast frequency bands will be available mainly for public safety purposes, for example, police and fire department concerns. Remaining portions of the old TV broadcast spectrum can be offered for technologically advanced applications such as wireless broadband. The use of digital-capable television sets allows American viewers more 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 but to convert millions of TV sets from analog to digital and give up the true 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 manner of transmitting broadcasts, signal content within a bandwidth in the broadcast spectrum, and the ability to broadcast in widescreen (169) format. Transmission Analog television transmission is based on and started after World War II with black 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 transmitted through the AM radio band while audio is transmitted 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 prone to ghosting and other video disturbances. Although analog transmission can accommodate all the technicalities of high fidelity reception, the assigned 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 well as audio. It handles information in the same manner as computers: on (with a binary value of â€Å"1†) or off (with a binary value of â€Å"0†). Digital broadcasts allow viewers to see uniform reception quality regardless of the distance from the transmitter. Either the digital television receives the broadcast or the TV screen remains blank (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 like High Definition (HDTV) signals. In contrast, analog TV broadcast can only send limited traditional video signals. Format The development of wide screen format programming allows the broadcast of the 169 format. Today, widescreen LCD television are getting more popular; but 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 show 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 stations 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 also take advantage of the internet which has become part of the lives of many, particularly the young generation. Considering the continuing evolution in information and entertainment technology we just have to follow the trend out with old, in with the new.

Karl Marx - Capitalist Alienation Essay -- Socialism Communism Labor

A century and a half ago, Karl Marx established a theory that today is known as the backbone to modern socialism and communism. Marx viewed the early capitalism of his own day as inherently exploitive. At the core of capitalist production is what is considered surplus value, the value left over after the producer (in Marx’s case, factory owner) had paid the fixed costs of production such as raw materials, machinery, overhead and wages. The left over amount was kept as profit, a profit that Marx saw that was earned from the sweat of the labor. Derived from his idea of surplus value was that of alienation. Marx gave an economic interpretation to alienation. People were alienated from their own labor; their work was appropriated by someone else and the work itself was compulsory, not creative; the cause was capitalism, and the cure was socialism. Marx believed that modern labor is an evolution of something that began centuries ago and encompassing everything from slave states to European feudalism right on up to today’s version of commercial capitalism; which, completed or perfected the capitalist technique of worker alienation. Marx is correct in saying that capitalism exploits the working class, and that working under capitalism is in fact â€Å"alienating†.   Ã‚  Ã‚  Ã‚  Ã‚  Worker alienation became an effective tool by which the capitalist could separate themselves from the laborers of their nations. The separation, however, was more to show a capitalist’s class status rather than having...

Music Magazine Stereotypes

Kerrang! magazine is a music magazine that is mainly based on rock music. It is published by Bauer Consumer Media in the United Kingdom. The magazine's name is onomatopoeic and refers to the noise made when playing a power chord on an electrical guitar. The target audience for this magazine would first and foremost be teenagers (mainly those 16+) and also those in their 20’s. Some of its viewers would be approximately in their 30’s (the same age as the people featured in the magazine).Or simply, people who admire rock and loud music as the magazine mostly centres on rock and punk music. You can tell that the target audience is mainly teenagers because the bands featured in this magazine have got principally teenage fans, and also the title itself appeals to teenagers and people in their late 20’s (the design of it is edgy which appeals to them). I have been carrying and investigation based on whether the famed magazine Kerrang conforms to genre conventions. Accor ding to my research, I personally believe that Kerrang does conform to genre conventions.The reason for my theory is pretty clear as nearly all the magazine covers for this magazine simply suggest the fact that it’s a rock magazine, starting from the name of the magazine, to the singers featured in it and finally to the layout of the magazine’s cover. Normally, most magazine, especially rock and punk magazine, try their very best in order to make their covers attractive and appealing. Magazine use well known singers or bands in order for it to be much more noticeable which will attract various kinds of audiences.Furthermore, magazines like to include special offers in their covers, as well as secondary images (apart from the main image) so that it would lure in audience. Normally, if they include secondary images, magazine attempt to put an image of a famous musician that is well liked by the audience (see figure one) so that it would attract people into buying it. Ker rang has used nearly all the conventions in order for them to symbolize the genre they’re representing.The name of the magazine suggests the fact that it’s a rock magazine due to the fact that it’s a sound made my an electrical guitars, and since most rock bands use electrical guitars rather than using an acoustic one or a piano, this verifies the fact that it’s a rock band. Moreover, Kerrang mostly feature well known rock bands such as Metallica, Paramore, Green Day and My Chemical Romance (See figure 2, 3, 4, 5,). Additionally, they normally include so many headlines, secondary pictures and special offers like other magazines such as NME to exert a pull on the audience (See figure 7).This magazine also includes a PLUS! section like NME magazines has, this is done to tempt the readers and to increase the immensity of the advertisements. Kerrang has a lot of similarities with NME regardless of the fact that they both are rock magazines. They both feature a lot of rock band such as My Chemical Romance in addition to the headlines and secondary images. This shows that they both conform to genre conventions. (See figure 4 and 8). They share other similarities such as the fact that they both try to cover up the all cover using additional headline as well as secondary images.Kerrang covers are almost all alike. All of them include a main image in addition to a special offer to increase the sales. Although, some of Kerrang’s covers don’t include secondary images or additional headlines. Some of their covers may be a bit dissimilar to the others as it could either be an exclusive edition or just some other reason. If you take a look at Figure 4 and Figure 9, you could spot the very noticeable difference which is firstly, there is only one image in Figure 9 whilst there are more than one (excluding the main image) in Figure 4.Other differences such as the fact that Figure 9 is a bit less messy than Figure 4 also stand out. Eve n though there are differences between the two, they is still a various amount of similarities between them such as the fact that the name is written in the same font and the same style, in addition to the fact that they both feature special offers as well as main images of famous rock musicians. From the front cover we can only see that their interests are conventional rock groups.Most of the front covers have a header listing some mainstream bands; the main image on most the front cover is of the lead singer of a mainstream rock group, and on the side they list other mainstream rock groups that are going to be in the magazine and also are advertising that they have posters of yet more majority rock groups. If we wanted to find out any more of their interests we would have to look inside the magazine at the table of contents. Furthermore, the font used to write the name of the magazine is filled with cracks and different, which suggests the idea that it’s rock music magazine .In addition to the colours used (black and white, orange and yellow) which are LOUD colours, which represent the magazine as a loud magazine. In conclusion, I think Kerrang magazines are very much similar to other magazine who also feature rock music. Like other magazines, Kerrang includes a main image, additional headlines, and secondary images, buzz words such as ‘FREE! ’ and also special offers. The magazine matches a lot of genre conventions because like other magazines, they try to represent heir genre through their cover and they succeed in a clever way.

A Look At Roman Imperial Portraiture - 1572 Words

Portraits of Vespasian and Trajan: A Look at Roman Imperial Portraiture The Roman tradition of art, particularly architecture and sculpture is rooted in adopting styles of the past to convey a particular message. The combination of Greek and Etruscan styles, such as in the Temple of Portunus in Rome, ultimately culminate to reference a new meaning and style that is independently roman. Similarly to architecture, the first Roman Emperor, Augustus, chose to liken both is architecture, by using stone and the orders, and his portraiture back to the Greeks. Romans emperors ultimately tend to use style association to portray propaganda for their particular platform, as a form of associative mass media. Two emperors that exemplify this†¦show more content†¦The depth of such wrinkles as well as the deep set and hooded eyes allow for a stark contrast within the lighting of the piece, further emphasizing the importance of such areas. Furthermore, Vespasian chooses to depict himself as bald, or at least balding. While other emperors, such as Vespasian s su ccessors, will choose to falsify a head of hair in order to capture some ideal of the self, Vespasian chooses to keep some of his key features in order to preserve and distribute his identity, all while hyper-emphasizing his age. Through his efforts of individualization and emphasizing his age, Vespasian ultimately directly references the old versitic style of the Roman republic in order to present himself as a common, hardworking man and politician. The traditional Roman Republican style of portraiture has been nicknames veristic or truth-like. Its name stems from the apparent hyper- realistic portrayal of its subjects. When looking at a single republican portrait, it appears to be individualized and puts emphasis on the physical effects of age upon the body, much like Vespasian s portrait. However, the distinction between realistic and veristic is important.
