Embodiment 1

[0046] An advertising insertion identification method based on IP live streaming, applied to the multimedia audio and video of radio, television and operators, including a central encoder, a set-top box management unit and at least one set of set-top boxes; the method includes;

[0047] Encryption of live stream, the central encoder encrypts the live stream;

[0048] For live stream verification, the set-top box verifies the encrypted live stream and feeds back the verification information to the set-top box management unit;

[0049] The key is dynamically issued, and the set-top box management unit transmits the dynamic encryption key to the set-top box and the central encoder in real time through the wired network.

[0050] Methods of encryption of live streams include;

[0051] (1) Encoder output, after the central encoder compresses the DC wave, the live stream data is output through TS encapsulation and UDP protocol;

[0052] (2), the encryption of the live stream, for ...

Embodiment 2

[0061] On the basis of embodiment 1, the advertisement insertion identification device of IP live streaming realized by implementing the advertisement insertion identification method based on IP live streaming is applied to the multimedia audio and video of radio, television and operators, including a central encoder and a set-top box management unit and at least one set of set-top boxes; it includes a live stream encryption module, a live stream verification module and a dynamic encryption module;

[0062] Live stream encryption module, the live stream encryption module encrypts the live stream through the central encoder;

[0063] The live stream verification module, the live stream verification module verifies the encrypted live stream through the set-top box, and feeds back the verification information to the set-top box management unit;

[0064] The dynamic encryption module, the set-top box management unit transmits the dynamic encryption key to the set-top box and the c...

Embodiment 3

[0075] On the basis of the above-mentioned embodiment, by appending figure 2 , for the video to be played frame by frame, for example, the domestic cable TV broadcast requirement is 25 frames per second, that is, the set-top box continuously plays 25 images per second, and the human eye cannot distinguish the short time between each image. time interval, so the picture is perceptually continuous.

[0076] When each frame of data is transmitted in the network, it will be encapsulated in TS format according to the requirements of wired network transmission. Each TS packet is 188 bytes, and a frame image will be divided into multiple 188 bytes after being encoded and compressed by the encoder. Packets are transmitted over the network. The structure of the first 188 packet of each frame is different from that of other packets in the same frame, and there is an additional PES Header field, which can be used to record the data information of the frame.

[0077] The ES part is the...

Abstract

The invention relates to a multimedia audio and video processing technology, and discloses an advertisement insertion identification method and device based on an IP live broadcast stream, which are applied to multimedia audio and video of radio and television and operators, and comprise a central encoder, a set top box management unit and at least one set top box, comprising; encrypting the live broadcast stream, wherein the center encoder encrypts the live broadcast stream; verifying the live broadcast stream, verifying the encrypted live broadcast stream by the set top box, and feeding back verification information to the set top box management unit; and dynamically issuing the key, wherein the set top box management unit transmits the dynamic encryption key to the set top box and the central encoder in real time through a wired network. On the basis of not changing the existing network architecture, the real-time identification of the advertisement insertion is realized through the simple transformation of the central encoder and the set top box terminal. The method adopted by the invention does not affect the playing of the live broadcast stream, does not cause derivative accidents, and is low in cost and difficult to crack.

Description

technical field [0001] The present invention relates to multimedia audio and video processing technology, in particular to a method and device for discriminating advertisement insertion based on IP live streaming. Background technique [0002] As cable TV tends to be digitalized, network bidirectional, and intelligently managed, TV media is the premier communication weapon in modern media, with a strong impact and a wide range of audiences. TV is almost a necessity in every household, and watching TV in leisure time is the main activity of the family. Therefore, TV advertising is also the most frequently contacted and influential form of advertising. Compared with other forms of advertising, TV advertising is more direct. Strong and highly reliable, although it has been greatly impacted by the Internet in recent years, TV advertising is still one of the most popular forms of advertising. [0003] At present, many provincial-level channels led by Satellite TV all over the co...
