METHOD AND DEVICE FOR VIDEO DATA TRANSMISSION FOR IMPLEMENTING SPECIAL MODES

摘要

The invention concerns a method comprising a step which consists in comparing a label to a value counted from a transfer clock to define the transfer time on the bus of a packet read on a recording medium. The invention is characterized in that for implementing a special mode or trick mode, it further comprises the following steps: calculating a difference between two consecutive packets based on the values of recorded labels; calculating an offset value based on said difference and parameters received on the bus defining the special mode; adding said offset value to the label value of the transmitted packet to obtain a new label value defining the transfer time on the bus of the following packet to be transmitted. The invention is applicable to the storage of MPEG data.
