In the future, the evolution of devices will turn anything into a screen to display content that will be viewable anywhere. The path for content delivery will be selected automatically during viewing from broadcasting or the internet according to the device and situation. The content provided by broadcasters will be viewable quickly and stably anywhere. It will also be connected to information disseminated by individuals and global content creators.
Research and development toward the realization of content viewing without users being aware of the transmission path, thereby eliminating the wall between broadcasting and internet service

To eliminate the aggravation of watching broadcasts on TV and online videos with smartphones, we are working on research and development that enables users to easily view content of broadcasters without worrying about the device or transmission path.
Transmission path abstraction technology removes the walls between devices: televisions that receive broadcasts and smartphones/PCs that mainly receive the internet transmission. Our research on low-latency distribution technology and technologies to send trigger signals will realize a mechanism that provides the same viewing experience as broadcasting on any screen, be it a TV, smartphone, or PC, etc.
EM (Event Message): Trigger signal contained in broadcast waves.
Event Messages are used to transmit data broadcast content and disaster information in coordination with TV broadcast programs.
MTE (Media Timed Events): Trigger signal that can be contained in MPEG-DASH streams.Media Timed Events are used for the synchronization and information presentation of website content.
We are working to realize technologies that enable viewers to enjoy content on any screen without being aware of whether it’s broadcast TV or the internet.
