1. A method for receiving broadcasting service information in a digital broadcasting system, comprising:
- detecting packets carrying broadcasting service information from Transport Stream (TS) packets received over a wireless network, the broadcasting service information being Program Specific Information/Service Information (PSI/SI);
counting the number of the detected PSI/SI packets;
storing the detected PSI/SI packets;
generating an interrupt signal for reading the PSI/SI packets, if the packet count number reaches a predetermined packet number;
reading the PSI/SI packets after generating the interrupt signal;
activating a timer when a PSI/SI packet is detected;
comparing the packet count number with 0, if the timer has counted a predetermined timer value; and
reading the PSI/SI packets if the packet count number is greater than 0.

Abstract
Provided are an apparatus and a method for receiving PSI/SI in a DVB-H receiver, in which packets carrying PSI/SI are detected from TS packets received over a wireless network and counted, and the PSI/SI packets are read if the packet count number reaches a predetermined packet number.

6. An apparatus for receiving broadcasting service information in a digital broadcasting system, comprising:
-
a Packet Identifier (PID) filter for detecting packets carrying broadcasting service information with a PID identical to a preset PID from received Transport Stream (TS) packets, the broadcasting service information being Program Specific Information/Service Information (PSI/SI); a packet counter for counting the number of the detected PSI/SI packets; a memory for storing the detected PSI/SI packets; an interrupt generator for providing an interrupt signal for reading the PSI/SI packets, if the packet count number reaches a predetermined packet number; a controller for setting the PID for filtering regarding the TS packets, and reading the PSI/SI packets, if the interrupt signal is received from the interrupt generator; and a timer for starting to count when a PSI/IS packet is detected, wherein if the timer has counted a predetermined timer value, the controller compares the packet count number with 0 and reads the PSI/SI packets if the packet count number is greater than 0. - View Dependent Claims (7)
