Serial Digital Interface for HDTV

H. Gaggioni, M. Ueda, F. Saga, K. Tomita, N. Kobayashi

Based upon the experience gained from the application of digital technology to 525/625 broadcast and production environments, it is acknowledged that the wide acceptance of new equipment takes place only after the market introduction of a digital serial interface. Recently the TV standards organizations of SMPTE and BTA have agreed to a new standard for digital serial transmission of studio HDTV signals. The overall transmission rate for a digital studio HDTV signal (1125-line, 2:1 interlace, with a 10-bit per component sample) is approximately 1.5 Gbits/sec, while its active payload is in the order of 1.2 Gbits/sec (for 1035/1080 active lines). This paper describes the practical development of a complete transmission system for the transport of serial HDTV signals for studio production and post-production applications. Furthermore, a description will be given of test results of transmission experiments over 100 m (approximately 300ft) of Belden 8281 (5C-2V) coaxial cable.
