概要

In order to verify feasibility of high quality service in "the digital broadcasting era" from the technical point of view, we have developed a digital broadcasting system prototype for 525-line progressive scanning signal (525p), which is compliant to the system for 12.5GHz-band communication satellite (CS), reported by Telecommunications Technology Council. 525p real-time video encoder, multiplexer, 525p IRD etc. were newly developed to realize real-time transmission of 525p signal via this prototype. In the transmission experiment via CS, we observed consistency with the result derived from the experimental CS transmission by BTA in spring 1995,as well as good re-production of 525p video and associated audio with two different IRDs at the different places from the transmission site.
