Transmitted Signal

In this paper, we use MATLAB software to build the physical layer transceiver of the Digital Video Broadcasting Terrestrial System (DVB-T) and Additive White Gaussian Noise (AWGN) is added into the transmitted signal during its transmission. The transmitted signal passes through modulation, demodulation, encoding and decoding processes the resulting demodulated signal is compared with the transmitted signal to calculate its Bit Error Rate (BER). Three modulation formats, QPAK, 16-QAM and 64-QAM are simulated and through various Signal to Noise (SNR) ratio to evaluate the system performance. Various encoding techniques such as Reed Solomon Code, Convolutional Code and Viterbi Decoding [1-6] have been implemented and through simulation to make detailed system performance analysis and comparison. detailed system performance simulation, analysis and comparisons.

Degree Of Innovation

Over the past decade, a major policy and regulatory problem for governments in Australia and elsewhere has been the implementation of strategies to switch from analogue to digital television broadcasting systems. Despite extensive debate, the transition to digital broadcasting remains fraught. What seems to be a technical matter conceals a range of intractable social, economic and cultural policy decisions. This article explores some of the challenges of digital television through the prism of an earlier, and often overlooked, transformation of television, namely the consumer-driven uptake of what can be called the ‘new television technologies’ of the 1970s and 1980s. These earlier forms of new television help to highlight several arguments: that television was not a stable object prior to digital broadcasting; that the connections between television and broadcasting have been contingent and provisional; and that a remarkable degree of innovation, disruption and adaptation has occurred at the fringes of the broadcasting system, leading to the creation of new audiovisual economies on the boundaries of the household and the market. The article then considers some examples of the ways in which this ‘household sector’ is developing as a new policy problem.

Analogue To Digital

TV broadcast systems are migrating from analogue to digital broadcasting system. Some countries in the world have completed this migration since a few years ago. America decided to stop broadcasting analog television in 2009. In Asia, Singapore launched this technology in 2004 and Malaysia implemented in 2006 (Depkominfo, 2009). With so many countries are migrating to digital broadcasting system, there are many business models that can be referred for organizing digital television broadcasts. In this writing, several business models that are used in the world will be reviewed and analyzed and the results can be a reference to determine the appropriate business model according to the organizers.
