This invention relates to the field of smart terminal technology and discloses a display device and a display control method. The display device includes a display and a controller configured to: when playing first media data with first media data parameters in a first projection window of a projection interface, in response to a second operation command for playing second media data in a second projection window, acquire second media data parameters of the second media data; if it is determined that the second media data does not meet the projection conditions, stop receiving the first media data and control the display to play the second media data in the second projection window; if it is determined that the second media data meets the projection conditions, control the display to continue playing the first media data in the first projection window and play the second media data in the second projection window. Applying this solution can improve the user's projection experience.

The application provides a video ABR method, device and system based on 5G mobile information opening, the method comprising: receiving a current ABR decision generated by a client of a mobile 5G network service for requesting to reduce the code rate of a next video segment based on MEC, and querying the current mobile network switching information and the instant video buffer length of the client; judging whether the current ABR decision is a misjudgment decision suitable for video playback quality optimization based on the mobile network switching information and the instant video buffer length, if yes, rejecting to execute the misjudgment decision and transmitting the next video segment to the client at the current video segment code rate corresponding to the client. The application can realize the optimization of video playback quality based on 5G mobile switching perception, effectively improve the video playback code rate of the user, and reduce the video picture code rate jitter rate and picture freezing rate, thereby effectively improving the quality of experience QoE of the user playing the video in a mobile scenario.

This invention discloses an IP broadcast audio processing method and system for a converged broadcast system, belonging to the field of IP broadcast technology. The method includes audio preprocessing and encoding, dynamically adjusting three sampling rates (16000Hz / 32000Hz / 48000Hz) using a three-dimensional decision model combining broadcast type, terminal computing power, and scene noise; audio interleaving and FEC redundancy generation; multi-terminal clock synchronization using the chrony NTP service combined with smoothing correction and drift suppression; packet loss detection and hierarchical compensation using a four-layer protection mechanism: interleaving for burst response, FEC priority error correction, unicast continuation, and local hierarchical compensation; audio noise reduction and synchronized playback; and iterative optimization and collaborative management. This invention enables seamless integration and unified management of four major broadcast types, solving problems such as poor coordination among multiple broadcast types, low synchronization accuracy, poor packet loss compensation, and insufficient noise reduction and terminal adaptability, significantly improving the playback quality and emergency response efficiency of the converged broadcast system.

The utility model relates to the technical field of passenger vehicles, in particular to an intelligent connection domain controller and a vehicle, and the intelligent connection domain controller comprises a circuit board, a radio chip, a shielding cover, an elastic part and a first shell; the radio chip is arranged on the surface of the circuit board, and the shielding cover is connected with the circuit board and covers the radio chip; the side, back to the circuit board, of the shielding case is provided with the elastic piece, and the elastic piece is pressed between the shielding case and the first shell. According to the intelligent connection domain controller and the vehicle, the problems of noise, sound interruption and unsmooth playing in the playing process due to the fact that a shielding structure of a radio on an existing intelligent connection domain controller is poor and playing signals are easy to interfere are solved.
