Citizen journalism has now become one of the most developed television program concepts. If the concept was initially more widely used in radio and online media, this time with easier and cheaper technology coverage and delivery of images, it is a concept that provides a place for people to become amateur journalist that can also be easily applied in the medium of television. Research raised the issue on how the concept and implementation of citizen journalism on television in the era of media convergence. The purpose of this study is to explain concepts and demonstrate the implementation of citizen journalism on television in the era of media convergence. Research used qualitative method in which data were obtained using literature study. Results of the study showed that the implementation of citizen journalism on television is also increasingly facilitated by the entry of the television in the era of media convergence, or different media mingle, such as television with printed, radio, and Internet media. The era of media convergence makes the concept of citizen journalism can be more developed, because the platform or media distribution is also increasingly varied for amateur journalist. However, the system equipment that must be provided, human resources that must be owned, as well as huge capital to be owned make a few television stations open a lot of platforms to provide space for amateur journalist in citizen journalism.

We consider the problem of streaming media transmission in a heterogeneous network from a multisource server to home multiple terminals. In wired network, the transmission performance is limited by network state (e.g., the bandwidth variation, jitter, and packet loss). In wireless network, the multiple user terminals can cause bandwidth competition. Thus, the streaming media distribution in a heterogeneous network becomes a severe challenge which is critical for QoS guarantee. In this paper, we propose a context-aware adaptive streaming media distribution system (CAASS), which implements the context-aware module to perceive the environment parameters and use the strategy analysis (SA) module to deduce the most suitable service level. This approach is able to improve the video quality for guarantying streaming QoS. We formulate the optimization problem of QoS relationship with the environment parameters based on the QoS testing algorithm for IPTV in ITU-T G.1070. We evaluate the performance of the proposed CAASS through 12 types of experimental environments using a prototype system. Experimental results show that CAASS can dynamically adjust the service level according to the environment variation (e.g., network state and terminal performances) and outperforms the existing streaming approaches in adaptive streaming media distribution according to peak signal-to-noise ratio (PSNR).
