Claims9
A transport stream demultiplexer which receives transport stream packets and outputs data included said packets, comprising a device for judging whether a received transport stream packet is a null packet, and, if said received transport stream packet is a null packet, prohibiting writing data included in said received transport stream packet thereinto.
A method of deleting memory traffic in a transport stream demultiplexer which receives transport stream packets and outputs data included said packets, comprising the steps of:
- (a) judging whether a received transport stream packet is a null packet;
- and
- (b) prohibiting writing data included in said received transport stream packet into said transport stream demultiplexer, if said received transport stream packet is a null packet.
A program for causing a computer to carry out a method of deleting memory traffic in a transport stream demultiplexer which receives transport stream packets and outputs data included said packets, said method comprising the steps of:
- (a) judging whether a received transport stream packet is a null packet;
- and
- (b) prohibiting writing data included in said received transport stream packet into said transport stream demultiplexer, if said received transport stream packet is a null packet.
