video data stream, audio data stream, or other encoded data streams. The es stream is converted to the PES package after it passes through the PES package. The PES package consists of a packet header and payload. The specific format is as follows:
We can see that PTS/DTS is in the PES package, and the two parameters are the key to solving synchronous display of video and audio and preventing the input cache overflow or underflow of decoder. PTS indi

. Although the maximum length of the PES package can reach (216-1) = 65535B (byte), but generally it is the length of one au consisting of the header and the encoded data in several AU s that constitute es. One AU is equivalent to one video image or one audio.Frame, see the es to PES in the upper-right corner of Figure 2. It can also be said that each Au is actually the display unit of the encoded data stream, that is, the sampling of a decoded video image or an audio frame.

Data Transformation Services
Exporting to the Comma separated file (CSV) can be used as a starting point for exporting data to SQL and importing from SQL, but it's not like cutting-edge technology (too 20th century, don't you think?). SQL Server 7.0 provides a fairly sophisticated import and export mechanism in the form of Data Transformation Services (DTS). Fo
