Patent attributes
A packet sending apparatus that improves packet transmission quality by preventing loss of packet information, while minimizing a reduction in transmission rate. A clock frequency deviation correction calculation section calculates a valid packet sending period in which valid packets packet information of which is not lost due to clock frequency deviation between the packet sending apparatus and a packet receiving apparatus are included and the number of valid packets included in the valid packet sending period. A packet sending section exercises priority control by determining whether a packet to be sent is a priority packet or a non-priority packet and by sending a priority packet in preference to a non-priority packet, and performs a packet sending process on a packet to be corrected other than the valid packets completely included in the valid packet sending period at the time of correcting the clock frequency deviation by inserting a packet gap corresponding to a sending stop period for which packet sending is stopped to prevent loss of packet information.
