With the development of digital TV technology, the ability of receiver to receive the service information in TS becomes more and more important. Firstly the PSI (Program Specific Information) in MPEG-2 and SI (Service Information) in DVB (Digital Video Broadcasting) are analyzed. Then a storage scheme for SI in DVB systems is presented. In this scheme, SI can be stored, retrieved, extracted and updated in real time and multitask environment. As data can be shared between PSI and SI, the requirement of the hardware resources is greatly reduced.
