3 What is SDI? Professional video application for uncompressed video production and delivery Studio TV station

4 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 qualityStandardData rateAspect ratioVideo resolution Standard Definition (SD)SMPTE259M DVB-ASI 270Mbps4:3480i (525i) 576i (625i) High Definition (HD)SMPTE292M1.485Gbps 1.483Gbps 16:9720p 1080i 1080p 3G-SDISMPTE424M2.97Gbps16:91080p
