Abstract
This paper describes the development of 525-line progressive scan (525P) digital broadcasting system, which provides cost effective high picture quality service. 525P is a type of progressive (non-interlaced) scan format and the scan rate is exactly double that of the conventional 525-line interlaced scan (525I). This format has several advantageous features; better picture quality compared with 525I, lower encoder/decoder implementation cost compared with HDTV, high compatibility with 525I. That's why the 525P format enables cost effective high picture quality services especially adequate for consumer use TV. The 525P digital broadcasting system prototype has been realized conforming to the digital broadcasting standard via communication satellite (CS) in Japan, which uses MPEG-2 video coding technology. For the implementation of 525P MPEG-2 encoder and decoder, Main Profile at High-1440 Level (MP@H14L) instead of Main Profile at Main Level (MP@ML) was used with a slight modification of MPEG-2 MP@ML encoder/decoder for NTSC/PAL service. This is the first implementation of real-time MPEG-2 encoder and IRD (Integrated Receiver Decoder) for 525P. MPEG-2 multiplexer for interfacing with 525P encoder was developed as well. Using this system, we have carried out several transmission experiments via CS and verified technical feasibility of high quality digital broadcasting service at the 525P video bit-rate of 9Mbps or around.
