Patent ID: 7681224

Claim:
A method of transmitting moving picture data between a delivery apparatus and a receiving apparatus connected by a network, said method comprising the steps of: on said delivery apparatus side, doubling packets of said moving picture data and starting to transmit said doubled packets of said moving picture data after the switching to a source is made according to a command to switch to said source of said moving picture data, said command being sent from said receiving apparatus, and at the same time, causing a counter to start counting so that, when the output from said an error corrector of said receiving apparatus becomes effective, said doubling of said packets of said moving picture data can be stopped, followed by the transmission of said moving picture data not doubled; and on said receiving apparatus side, restoring said doubled packets of said selected moving picture data to the original single-part packets with the lost packets compensated for, correcting said restored moving picture data by said error corrector, and at the same time, until said error corrector produces corrected data, causing said moving picture data not corrected yet to be processed by a decoder so that a frozen frame of said moving picture data can be produced and displayed.
