  33. Challenge 10: Retail & Standards • It’s not easy: • Retail channel wants to duplicate DSS business model with subsidy and annuity for each STB sale • Retail channel & vendors want “one architecture” • Consumer Electronics vendors want standards but complete freedom to innovate as well as subsidy and annuity • Consumer Electronics vendors want to integrate STB into TV and other devices without cost impact • Existing head end and STB vendors want their proprietary CA and upstream systems to continue in the market • The EPG problem is a whole presentation just by itself • ISPs and AOL want completely open access platform • Broadcasters want support for all video and data formats • PC vendors want progressive scan
