AI Technical Summary

Technical Problem

In the existing audio and video transmission network, the root nodes in the tree network independently manage their own child nodes, resulting in the inability to coordinate the management of bandwidth and other resources between different root nodes, resulting in a low bandwidth utilization rate.

Method used

A bandwidth negotiation method is provided, which sends bandwidth negotiation requests and responses by initiating a UMI bus connection between the device and the target device, allowing the target device to judge whether it agrees to conduct bandwidth negotiation based on its own service flow situation, thereby realizing the coordinated management of bandwidth resources.

Benefits of technology

Through the bandwidth negotiation method, the initiating device and the target device can effectively utilize the free bandwidth resources of the target device and improve the bandwidth utilization rate of the audio and video transmission network.

Abstract

The invention discloses a bandwidth negotiation method and device, and relates to the technical field of multimedia. An initiating device in an audio and video transmission network can perform bandwidth negotiation with a target device by sending a bandwidth negotiation request to the target device. Meanwhile, the bandwidth negotiation request comprises a first outflow bandwidth value and / or a first inflow bandwidth value, so that the target equipment can sense an outflow bandwidth target value needing to be negotiated and an inflow bandwidth target value needing to be negotiated, whether bandwidth negotiation is agreed or not is judged according to the service flow condition of the target equipment, and then the bandwidth negotiation request is returned; therefore, the initiating device and the target device can perform collaborative management on the bandwidth resources, so that resources such as idle bandwidth of the target device can be utilized, and the bandwidth utilization rate of an audio and video transmission network is improved.
