A dynamic code rate adjustment data transmission method based on HDMI comprises the following steps: initializing a sending end MJPEG video encoder and a PCM audio encoder, and requesting to allocate an IP address; monitoring a multicast message sent by a receiving end, obtaining a paired receiving end and storing an IP address of the paired receiving end; starting an MJPEG video encoder and a PCM audio encoder, and setting a video encoding code rate, a frame rate, an audio encoding format and a bit rate; an HDMI input source signal is detected, if the HDMI input signal is detected, MJPEG and PCM data buffer memories are allocated, a video code rate code table is initialized and adjusted, and PCM coding and network sending processing and MJPEG coding and network sending processing are started; and circularly monitoring the multicast message of the receiving end, updating the IP address of the receiving end if the serial number in the received message is the same as the serial number in the sending end, and then continuously monitoring. Through congestion control in the data transmission process, the HDMI signal long-distance transmission quality and stability can be effectively improved, and the problem that long-distance transmission wiring is difficult is solved.

The application provides an audio sharing method and related equipment, and relates to the technical field of communication. The audio sharing method comprises the following steps: copying audio data to be played to obtain first audio data corresponding to a first wireless earphone and second audio data corresponding to a second wireless earphone; using a first protocol stack processing module to encode the first audio data based on an audio coding format of the first wireless earphone and send the first audio data to the first wireless earphone; and using a second protocol stack processing module to encode the second audio data based on an audio coding format of the second wireless earphone and send the second audio data to the second wireless earphone. By using the above method, the audio data to be played is divided into multiple parts, each part corresponding to a wireless earphone, and the virtualized multiple protocol stack processing modules can perform differentiated processing on each part of the audio data. Each part of the audio data can be independently encoded and adjusted in volume and sound quality, so that multiple wireless earphones can play audio with different coding formats, different volumes and different sound qualities.

This disclosure provides a two-way intercom method and electronic device for use in a kitchen environment, relating to the field of Internet technology. The method includes: receiving a message sequence from a kitchen monitoring terminal; wherein the message sequence contains payload data using an MPEG-2 program stream encapsulation format; based on the encapsulation header identifier in the payload data, converting the payload data into a distribution data stream conforming to a streaming media protocol and distributing it to a client, the client being used to play video footage and audio from the kitchen environment; acquiring an intercom audio stream for the monitored content in the payload data; wherein the encoding format of the intercom audio stream matches the audio encoding format in the payload data; and in response to an intercom command sent by the client, pushing the intercom audio stream to the kitchen monitoring terminal through a voice feedback link established with the kitchen monitoring terminal. This disclosure embodiment achieves two-way real-time intercom functionality between the client and the kitchen monitoring terminal while maintaining compatibility with existing national standard equipment.
