4 results about "Delay equalization" patented technology

The invention provides a digital human live broadcast method, system and device and a storage medium, and the method comprises the following steps: collecting user interaction data of a live broadcast platform in real time, and analyzing the user interaction data to obtain an analysis result; a live broadcast atmosphere index is calculated according to the analysis result, and response content and an interaction instruction are generated through an inner loop fuzzy controller according to the live broadcast atmosphere index; according to the response content and the interaction instruction, in the process of generating the audio data through the text-to-voice unit, executing predictive delay equalization processing on the audio data generation stream to obtain a stable audio data stream; and the stable audio data stream and the digital human video stream are synchronized and then pushed to a live broadcast platform. The method can provide clear and smooth digital human live broadcast service with high emotional quotient and high intelligence quotient for the user, and has remarkable technical advantages and commercial application prospects.

The application discloses a group time delay equalization circuit, an automatic equalization system and method, the group time delay equalization circuit comprises an adjustable group time delay equalizer in a single-stage structure or a multi-stage cascade; the group time delay automatic equalization system comprises a frequency conversion channel to be optimized, a vector network analyzer to test a group time delay, a group time delay equalizer, a host computer and control software; after the final target group time delay fluctuation parameter of the frequency conversion channel is determined, the initial parameters of the frequency conversion channel and the group time delay equalizer are tested, and the control voltage of the group time delay equalizer is adjusted in cooperation with the control software, so that the group time delay fluctuation of the frequency conversion channel and the group time delay equalizer in cascade satisfies the target requirement, and the application has great flexibility and practicality.

The invention discloses a multi-path RTP delay equalization sending system and method based on an FPGA, and relates to the technical field of data transmission, and the FPGA comprises an audio acquisition module, a first-level cache, a second-level cache, an RTP packaging module, a UDP / IP protocol stack module and a gigabit Ethernet interface. The audio data of the audio channels are written into the first-level cache for multiple times at the end of each channel, are read out from the first-level cache for multiple times at the end of each sampling and are written into the second-level cache, and RTP message packaging is started every time writing into the second-level cache is completed; the RTP packaging starts to package for the first time after the 48th sampling point is completed, and then data of the latest 48th sampling points are taken in each cycle. Through temporary storage of the first-level cache and cyclic updating of the second-level cache, data dispersion packaging and sending of the RTP flow are achieved, RTP flow delay equalization and network bandwidth occupation equalization are achieved, the requirement for the peak forwarding performance of a switch in the multi-device environment is lowered, and the problem of network congestion is effectively solved.
