Cinema, which started to digitalize in the 20th century, continues to be integrated with digital publishing platforms that emerged with the development of new media technologies in the 21st century. With the coronavirus pandemic that affected the whole world in 2019, digital broadcasting platforms became popular as an alternative cinema event in the quarantine process. Various precautions have been taken around the world for the coronavirus pandemic. As a result of the quarantine precaution, the local and global cinema industry was negatively affected. Cinema industry which is a collective production and screening process, has been interrupted by the suspension of the filming and the closing of the movie theaters during the quarantine. New media created a movement area for the cinema industry in this process. In this sense, the aim of this study is examining the researches on the effect of the coronavirus pandemic on the cinema and the effect of new media tools and opportunities on the cinema sector.

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.

Configuration Control

There is a way to automatically wake up television receivers when a broadcaster sends out an emergency alert. In the Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) digital television standard, the emergency wake-up procedure is called an Emergency Warning System (EWS). In ISDB-T, the special signal is embedded in a control message known as transmission and modulation configuration control (TMCC). However, improper identification of the wake-up signal, often encountered in mobile reception, leads to unnecessary wake ups. In this paper, a method of reliably determining a wake-up signal is proposed by assuming that broadcasters will not change the TMCC message except for the wake-up signal when the broadcaster sends out an emergency alert. A change in the wake-up bit leads to variation parity, and the proposed method also relies on such variations. Mutual information to be obtained by the wake-up receiver is evaluated using the memoryless binary asymmetric channel model. Results showed that the proposed method provided mutual information even at a Eb/N₀ being lower than 10 dB. Mutual information of the proposed method with intermittent reception is also analyzed as a function of the duty ratio of the intermittent receiver.
