TS (Transport Stream) transmission method and device

The invention discloses a TS (Transport Stream) transmission method and device, and the method comprises the steps: respectively determining all two adjacent program association tables in an original TS as a first program association table and a second program association table by a server; randomly inserting at least one false TS packet between a first TS packet where a first byte of the first program association table is located and a second TS packet where a first byte of the second program association table is located to obtain a modified intermediate TS stream, encrypting the intermediate TS stream by adopting a preset encryption rule to obtain an encrypted target TS stream, and sending the encrypted target TS stream to the client. According to the invention, the initial position of each real TS packet in the original TS stream is disturbed by randomly inserting the false TS packet in the original TS stream, and position coding and encryption are carried out on the insertion position of the false TS pack
