The embodiment of the present invention discloses a system and method for intelligently adjusting the real-time live streaming code rate of an IP camera. Network speed; set the clipping limit points synchronized with the uplink network speed time node at the upper and lower positions of the original video data; add a data clipping blank layer to the clipping limit point of the original video data; clip the data clipping blank layer The original video data after cutting and the original audio data are asynchronously classified and encoded, and the maximum data size that can be transmitted by the compressed and encoded audio data stream and the target video data stream is monitored in real time, and the cutting depth of the data cutting blank layer is adjusted; the audio data stream and the The target video data stream is pushed to the live server synchronously. This solution monitors the speed of the uplink network in real time, automatically adjusts the data upload bit rate, keeps the link of the live broadcast terminal constant, and improves the viewing experience.

The invention provides a microphone-connected live broadcast method and related equipment, and the method comprises the steps: obtaining an original audio input by an anchor in real time based on a terminal, and a target tone selected by the anchor based on the terminal when any terminal triggers a voice-changing live broadcast mode in a live broadcast process of a plurality of terminals in microphone connection; performing timbre conversion on the original timbre in the original audio based on the target timbre to obtain a converted target audio; and carrying out stream mixing on the target audio and the obtained original audio input by other microphone-connected terminals to obtain a stream-mixed audio, and sending the stream-mixed audio to all microphone-connected terminals and audience terminals entering the microphone-connected live broadcast room. In the scheme, the server performs timbre conversion on the original audio input by the terminal triggering the voice-changing live broadcast mode in real time to obtain the target audio. Therefore, audiences entering the live broadcasting room can watch the target audio conveniently. The microphone-connected live broadcast is carried out in the mode, so that the live broadcast watching experience of the user can be improved, and the viscidity of the user to the live broadcast platform is improved.

The invention discloses a video live broadcast oriented code rate self-adaption method based on a finite-state machine. The method comprises the steps of bandwidth estimation, preprocessing of historical observation data through Klehman filtering, inter-frame differential denoising and improvement of bandwidth estimation accuracy according to probability statistics and confidence confirmation. Buffer areas are graded, security buffer thresholds and danger buffer thresholds of different sizes are set for bandwidths of different levels, and the security buffer thresholds and the danger buffer thresholds are added into a code rate decision mechanism of the state machine; and time delay control: a change trend of a future cache is obtained according to the current bandwidth and the selectioncode rate so as to dynamically adjust and determine a variable of a fast and slow playing threshold of the player. According to the method, available bandwidth is fully utilized from three aspects ofbandwidth estimation, buffer area grading and time delay control, video switching frequency is reduced while video quality maximization and low time delay are guaranteed, video live broadcast smoothness is improved, watching experience of a user is greatly improved, and the method can be effectively applied to the fields of network video live broadcast and the like.

The application provides an intelligent live broadcast method, a wearable device and an intelligent live broadcast system, which relate to the field of virtual reality technology, and can intelligently display the target image selected by the user in the live broadcast without the user needing to actively search for the target object, saving the user's time , so that users can get a better live viewing experience. The method is applied to a wearable device, and includes: receiving a target panoramic video and first coordinate information, the target panoramic video contains a target image, and the first coordinate information is used to indicate the position of the target image in the target panoramic video First position; acquire second coordinate information, the second coordinate information is used to indicate the posture of the wearable device; based on the first coordinate information and the second coordinate information, the wearable device displays the A target frame of the target panoramic video, where the target frame includes the target image.
