IMAGE PROCESSOR AND IMAGE PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To enable to reduce processing load. SOLUTION: A host CPU 41 stores a PAT (program association table) packet, a PMT (program map table) packet, and a DIT (discontinuity information table) packet to be inserted to an extracted TS (transport stream) into an insertion packet buffer 91. The host CPU 41 outputs a control signal to open a gate 92 to a changeover switch 93 in a timing of inserting the DIT packet. A comparison section 94 outputs the control signal to open the gate 92 to a changeover switch 93 for every period when the PAT packet or the PMT packet is inserted. The changeover switch 93 selects the received control signal and outputs it to a gate 92 to open the gate 92. A packet insertion section 82 reads the packet from the insertion packet buffer 91 to insert it to the extracted TS.
