Digital Broadcasting Digital TV Prototype Flexible Oled Display Construction
A fine pattern of developed blue fluorescent OLED by using mask vapor deposition and made a color video display has been fabricated. This research will continue with the development of new materials that can be used with a printing method to make a large-screen/high-definition display construction.
Fast response and high-contrast organic light-emitting diode (OLED) will be used in future thin, lightweight, and flexible TV displays. STRL has been conducting research on flexible displays with the goal of constructing a large-screen home TV system for Super Hi-Vision (SHV) programmes.
Update
technology with the interactive capabilities of the Internet. The Japanese broadcaster hopes to commercialise the new technology and have it in consumers’ homes by next year.
At this year’s NHK Science & Technology Research Laboratories Open Day, NHK showed prototype receivers – developed together with equipment manufacturers – as well as a prototype of the new iTV service. Sony, Toshiba, Panasonic, Sharp and Mitsubishi Electric have each developed receivers for the Hybridcast concept.
When used with live sports broadcasts, updates about the game and players can be synchronised with the broadcast timeline and superimposed on the screen. The service uses HTML5 applications that can be displayed even on portable tablets. For example, if you’re watching a travel program, you can show where the subjects on TV are walking on a map. And if you’re watching a quiz program, you can take part by answering the questions. By using technology that supports interoperability between TVs and various terminal devices, it is possible to implement services that use different screen sizes in different ways. This includes large screens for TV viewing to using hand-held terminals to display information tailored to each individual viewer. (Broadcast Engineering)
ATSC Adopts Standard for Transmission of Non-real-time DTV Content

The Advanced Television Systems Committee (ATSC) has announced the approval of the ATSC NRT (Non-Real- Time) Content Delivery standard, a backwards-compatible enhancement to digital TV broadcasting that provides a framework for the delivery of a broad range of new services.
The new ATSC NRT standard is designated “A/103.” The delivery of non-real-time services via A/103 will now allow broadcasters to deliver file-based content, including programs and clips, information for emergency alerts and even commercial applications such as digital signage.

The ATSC NRT broadcast standard will support terrestrial transmission to both fixed location and mobile DTV receivers designed to make use of the new flexibility. Such a system would allow a user to watch on-demand a specific program that has been cached to the mobile device. Applications thought to be strong for NRT services include push VOD content, news, information and weather services, personalized TV channels, music distribution and mobile emergency alerts.
