What is the difference between ASI and TS Stream?

TS Stream is the source of the stream, the highest rate of 44.209 Mbit/s, it is a source code after the compression stream, in order to transmit the source information in the transmission rate under certain conditions for faster and more transmission, but also to compress the data, that is, through the source code to remove unnecessary parts of the information, In order to improve the effectiveness of communication, the source code includes Hoffman code, LZ code and many others.
The TS stream is the MPEG 12 transport stream,
MPEG 12 is the moving Pictures Expertgroup, which is the main target for transmitting sound, image data compression
Quasi -. The key compression technology in MPEG is DCT, Huffman coding, etc., but it has a significant development in image compression function. In MPEG 12, the image has 3 types of encoding: in-frame encoded image is called I-frame, two-way predictive encoded image called B-frame, forward-prediction-encoded image called P-frame, first I-frame, and then the P-frame, p-frame is the previous I-frame for the prediction frame encoding. Inserting people in the I-frame and P-frames
2 B-frames, frame order of IBBPBBPBBIBBP? I, P, B group of synthetic image group, plus sequence start code and sequence first class data compose image sequence or MPEG 12 basic bitstream es (elementary Stream). Basic code stream can not be transmitted directly to the channel, it needs to be packaged and reused to form a single MPEG 12 transmission stream for transmission, video, audio and data basic stream ES is packaged into a series of unequal PES packets, each PES packet with a Baotou, containing the type of packet, length and other relevant information. The PES packet of video, audio and data follows a common time benchmark, which forms a single program stream after program reuse, and becomes the final output signal stream of MPEG 12 source code.

SPI, ASI, DS3 are channel code flow, that is, in the source code to add a certain number of redundant code elements, so that the size of a certain anti-jamming ability, which is the channel encoding, the purpose of channel encoding is to ensure the reliability of information transmission. Among them, ASI and SPI interface are more commonly used.
ASI is a non-synchronous serial interface that uses a fixed transmission bitrate 270mbit/s to transmit MPEG 12 transmit stream signals of different bitrate, channel encoding 8 B/10 B, using ASI interfaces for longer distances (e.g., internal video networks), The ASI interface first converts the packet synchronization MPEG 12 transfer packet 8 bit code word to the L0 bit code word, and then through the parallel/String conversion unit programming fixed bitrate 270 serial signal, by the input code rate difference, need to insert the synchronization word in the TS Stream, to achieve the fixed rate of Mbps, The resulting serial bit stream will be sent through the buffer/drive circuit and the coupling network to the coaxial cable connector, when receiving data through the coaxial cables to the receiving end, the first to go through the connector and coupled network, the use of phase-locked loop clock recovery and data recovery, and then string/and transform, in order to restore byte synchronization, You must delete the inserted synchronization word.
