ABSTRACT:
An MPEG-2 transport stream packet detection device includes a controller for generating a detection start control signal and a series/parallel output control signal, and a sync detector for detecting an MPEG-2 transport stream packet sync from MPEG-2 transport stream data transmitted from the network according to the detection start signal from the controller, and a packet counter for counting a predetermined number of bytes according to a sync detection signal from the sync detector and sending a packet reception completion signal to the sync detector when finishing counting the predetermined number of bytes during a declaration of the detection signal, and a bit counter for counting a predetermined number of bits according to the sync detection signal from the sync detector and generating a signal for converting series data to parallel data when finishing counting the bits during the declaration of the detection signal, and a buffer for converting the series data and clock from the sync detector into parallel data and strobe signal according to the signal generated by the bit counter, and outputting the data and clock in series or parallel according to the series/parallel output control signal generated by the controller.
