What is SDI? • • • Professional video application for uncompressed video production and delivery Studio TV station
SDI and SMPTE • SDI is an interface for uncompressed digital video transmission over coaxial cable • SMPTE is a professional association which establishes standards, practices and guideline for motion picture and TV industry Video quality Standard Data rate Aspect ratio Video resolution Standard Definition (SD) SMPTE 259 M DVB-ASI 270 Mbps 4: 3 480 i (525 i) 576 i (625 i) High Definition (HD) SMPTE 292 M 1. 485 Gbps 1. 483 Gbps 16: 9 720 p 1080 i 1080 p 3 G-SDI SMPTE 424 M 2. 97 Gbps 16: 9 1080 p
