AI Technical Summary

Problems solved by technology

However, various multimedia system solutions based on embedded systems on the market generally have the following disadvantages: 1) weak performance

Most embedded multimedia solutions on the market are unable to meet people's higher and higher display resolution requirements due to their insufficient chip capabilities, limited decoding capabilities, and insufficient support for high-resolution displays.

2) Insufficient scalability

These chips are designed according to a specific application environment, based on the embedded multimedia platform designed by it, so they can only focus on a certain application field, making the solution itself very insufficient in flexibility and scalability. 3) Interaction with users Way too single

This interaction method is too mechanical, and users often struggle to remember the functions of each button

At the same time, in the process of system operation, the system only mechanically completes the tasks assigned by users, and lacks interaction with people in the process of task execution, making it difficult to give people a sense of intimacy
