5. IEC TC 100 2008-10-10 5 5 A series of international T-DMB standards are under way Series 1 : IEC 62516-1: Terrestrial Digital Multimedia Broadcasting (T-DMB) Receivers - Part 1: Basic requirement Series 2 : IEC 62516-2: Terrestrial Digital Multimedia Broadcasting (T-DMB) Receivers - Part 2: interactive data service using BIFS (Binary Format For Scene) Series 3 : IEC 62516-3: Terrestrial Digital Multimedia Broadcasting (T-DMB) Receivers - Part 3: T-DMB Common Command Set (TCCS) Standardization - Why needed?

6. IEC TC 100 2008-10-10 6 6 Standardization - Why needed? The development of diverse receiver chipsets and devices, such as mobile phones, USB dongles, car navigations, PNPs/PNDs, etc. has increased the industry demand for a common T-DMB API that can operate in multiple platforms. The T-DMB software is heavily dependent on receiver chipset, OS, and device environment, which results in waste of time and effort due to repeated design tasks. A standardized Common API that can be easily used in multiple platforms is needed
