Method and apparatus for processing transmission error in DMB system
First Claim
1. A transmission error processing method comprising:
- detecting an error for an individual PES (packetized elementary stream) after detecting transmission error information from a received MPEG-2 transport stream (TS) including the transmission error information and demultiplexing the MPEG-2 TS into a plurality of PESes;
recording data of the individual PES in a memory and adding a flag indicating that an error occurs to the data of the individual PES, and afterwards recording the data of the individual PES; and
generating an interrupt according to the error detection.

Abstract
Provided are a method and apparatus for detecting and processing transmission errors of various types of data which are transmitted in MPEG-2 transport streams. The transmission error processing method includes: detecting an error for an individual PES (packetized elementary stream) after detecting transmission error information from a received MPEG-2 transport stream (TS) including the transmission error information and demultiplexing the MPEG-2 TS into a plurality of PESes; recording data of the PES in a memory and adding a flag indicating that an error occurs to an end part of the data of the PES, and afterwards recording the data of the PES; and generating an interrupt according to the error detection.

6. A transmission error processing method comprising:
-
transferring a write address that is a location where an MPEG-2 demultiplexer records data in a memory and the number of the recorded data to a processor through an interrupt; and
performing an interrupt service routine that processes the interrupt according to the received write address and the number of the recorded data. - View Dependent Claims (7, 8)

9. A transmission error processing apparatus comprising:
-
an outer-decoder extracting error information after receiving an MPEG-2 TS including transmission error information;
a TS demultiplexer demultiplexing the MPEG-2 TS into a plurality of PESes, and generating an error signal for each individual PES, and informing an occurrence of an error through an interrupt; and
an interrupt processing unit recording the data of the individual PES in a memory, and adding a flag indicating that an error occurs to the end part of the data of the individual PES, and recording the data. - View Dependent Claims (10, 11)
