The invention relates to a basic encode stream data pack checking method with pack head in digit TV, wherein it comprises: receiving TS stream, judging if the PES data pack of TS stream is the first byte data pack initialize mode at one unit; if it is, recovering the initialize mode, and storing the first byte PES data pack; if it is not, judging if it is the continuous data pack received only after the first byte data pack; if it is not the initialize mode and continuous data pack, judging if it is discontinuous data pack; if it is not initialize mode and discontinuous data pack, confirming it as initialize mode and continuous data pack, and displaying one interrupt signal that ending one unit data pack storage. The invention detects the start and end of PES in TS stream and informs the user. |
