Embodiment 1

[0022] According to an embodiment of the present invention, an embodiment of a method for converting a TS code stream into an RTP code stream is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in a computer such as a set of computer-executable instructions system, and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0023] figure 1 It is a flowchart of a method for converting a TS code stream into an RTP code stream according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0024] Step S102, acquiring the target TS code stream.

[0025] The TS specification uses the TS packet encapsulation format to multiplex the video and audio streams and transmit them in a single stream. The TS code stream data packet length is fixed ...

Embodiment 2

[0075] The following will combine image 3 The method for converting the TS code stream into the RTP code stream provided by the present invention is described.

Abstract

The invention provides a method and device for converting a TS code stream into a RTP code stream, and relates to the technical field of multimedia. The method comprises the following steps: acquiring the target TS code stream; searching a PSI table in the target TS code stream to obtain a target result, wherein the PSI table is used for indicating program description information; splitting the target TS code stream according to the target result to obtain ES data; encapsulating the ES data according to a real-time transmission protocol standard to obtain a RTP data packet, and transmitting the RTP data packet to the terminal equipment according to a network transmission rate at the current moment, thereby relieving the technical problem that the data in the broadcast TV system cannot be directly sent to an Internet live system in the prior art.

Description

technical field [0001] The invention relates to the technical field of multimedia, in particular to a method and a device for converting a TS code stream into an RTP code stream. Background technique [0002] TS (Transport Stream) is an encapsulation format for sub-packet transmission applications. Its application is mainly digital video broadcasting of coaxial transmission, and supports a variety of basic media streams and various media coding standards (MPEG-2, MPEG-4, H.264, H.265 and AVS, etc.), easy to expand. TS has been widely used on a large scale for more than ten years, and has been unanimously recognized by the global broadcasting industry and the Internet industry. Currently, there are three digital TV standards: Advanced Television System Committee (ATSC for short), Digital Video Broadcasting (DVB for short), and Integrated Services Digital Broadcasting (ISDB for short), all of which are based on MPEG TS. . [0003] The Real-time Transport Protocol (RTP) is a...
