Storage scheme of system information for digital television receiver

This paper presents a storage scheme of system information for a digital television receiver. The proposed configuration is based on MPEG-2/DVB (Moving Picture Experts Group/Digital Video Broadcasting) standards. The corresponding software for system information processing has been implemented and runs under the real time and multitask operating system. System information consists of SI (Service Information) and PSI (Program Specific Information). As the data in the memory of the DTV receiver can be shared between the SI and PSI, the requirement of the memory resource is reduced. An improved version of the system information identification is also proposed.
