Embodiment 1

[0042] A slow live broadcast architecture based on multi-camera, including a playback terminal and at least one set of playback collection terminals; it also includes a multi-camera live broadcast subsystem;

[0043] The playback collection end transmits the signal source to the multi-camera live broadcast subsystem through the real-time streaming protocol RSTP;

[0044] The multi-camera live broadcast subsystem processes the received signal source and transmits it to the playback terminal through the user data packet protocol UDP, and the playback terminal plays the signal source.

[0045] The multi-camera live broadcast subsystem includes a multi-camera information source aggregation module, a multi-camera information source merging module and a multi-camera management module;

[0046] Multi-camera information source aggregation module, the multi-camera information source aggregation module is used to rectify the reception of different signal sources;

[0047] Multi-camera ...

Embodiment 2

[0055] On the basis of Embodiment 1, this embodiment provides a multi-camera-based slow live broadcast method, including a playback terminal and at least one group of playback collection ends; it also includes a multi-camera live broadcast subsystem; the method includes;

[0056] For the transmission of signal sources, the playback and acquisition end transmits the signal sources to the multi-camera live broadcast subsystem through the real-time streaming protocol RSTP;

[0057] Signal source processing, the multi-camera live broadcast subsystem processes the received signal source and transmits it to the playback terminal through the user data packet protocol UDP;

[0058] The playback of the signal source, the playback terminal plays the signal source.

[0059] Signal source processing methods include:

[0060] The deployment of the multi-camera information source aggregation system connects the signal source collected by the playback acquisition terminal to the multi-camer...

Embodiment 3

[0068] On the basis of the foregoing embodiments, a multi-camera information source aggregation module in this embodiment is provided. Deploy the multi-camera information source aggregation module in the scenic area or the edge aggregation computer room. Here, the playback and collection ends are various cameras. The signals of various cameras are first connected to the multi-camera information source aggregation module, and the TS Over is output through the multi-camera information source aggregation module. UDP; the multi-camera information source aggregation module is mainly used to rectify different types of signal sources at the front end to facilitate the combination of multi-camera information sources.

[0069] The multi-camera management module is mainly responsible for defining information source merging rules, including the overall canvas layout of information source display, such as 4 grids and 9 grids, as well as the display position of each channel of information s...

Abstract

The invention relates to a multimedia audio and video processing technology, and discloses a slow live broadcast architecture and method based on multiple cameras, which are applied to multimedia audios and videos of radio and television and operators, and are characterized in that a playing acquisition end transmits a signal source to a multi-camera live broadcast subsystem through a real-time stream propagation protocol (RSTP); and the multi-camera live broadcast subsystem processes the received signal source and transmits the processed signal source to the playing terminal through a user data packet protocol UDP, and the playing terminal plays the signal source. According to the method, front-end acquisition facilities and network transmission and distribution requirements of the slow live broadcast signals do not need to be changed, a set of multi-position live broadcast subsystem is additionally arranged at the center end of the platform, and multiple paths of gathered slow live broadcast signals are classified, reprocessed and subjected to personalized processing, so that multiple paths of similar slow live broadcast signals can be gathered on the same broadcast code stream; the terminal can present multiple paths of slow live broadcast signals at the same time, click amplification and interaction are carried out on the slow live broadcast signals, and the increasing personalized watching requirements of users are met.

Description

technical field [0001] The invention relates to multimedia audio and video processing technology, in particular to a multi-camera-based slow live broadcast architecture and method used in radio and television and operators. Background technique [0002] With the gradual upgrading of the Internet and mobile platforms, the digital transformation of the TV industry has begun, and the advantages of a single structure inherent in traditional TV are gradually weakening, while mobile platforms are beginning to occupy more market share in live broadcasting, including content and form innovations . At the same time as the proportion and share changed, another live broadcast ecology began to appear. This live broadcast ecology directly conflicted with the conventionally recognized live broadcast form and became the reverse of "fast live broadcast", thus deriving another live broadcast form. People in the industry understand it as "slow live broadcast". "Slow live broadcast" innovate...
