A comparative study of some of today's systems in video transfer and broadcasting (English)
SVT is Sweden’s largest TV-network and broadcasts more then 22 000 hours of TV each year. SVT is a public service company where the basic idea is to reflect the world from different perspectives and news is very important for providing neutral and versatile information in a variety of areas. An important part of the flow of information is to continuously receive reports from all corners of the world around the clock. This places very high demands on the technology used and it is important that it function and develops to meet current and future growing needs. One of SVTs vision is to increase the proportion of live reports in news broadcasts and self produced news reports from remote locations and is therefore interested in new technologies that offer greater topicality and lower cost for the reports. There are two different technologies used in the present situation, Store and Forward and Live. The difference between them is that at the Store and Forward the reporter sends a complete edited feature back to the news room. When doing a Live the reporter simply performs a live reporting. During the project a technical comparison between today’s products has been performed, the comparison has highlighted advantages and disadvantages of these products video and audio coding and data transmission. Even a comparison of their ease of use and functionality has been conducted and results are to be the basis for a set of requirements for additional procurement of large scale purchases of new systems. The results have shown that the system from the English company Quicklink is the one that performs best image quality overall for both Store and Forward and Live. The system has a well working interface with many smart features and is also easy to use in a large scale environment. All these features make the application from Quicklink best suited for SVTs needs.
