Architecture of a T-DMB Receiver

IEC TC IEC TC 100100 2008-10-102008-10-1055

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?

IEC TC IEC TC 100100 2008-10-102008-10-1066

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
