VIDEO BANDWIDTH ADAPTING DEVICE AND ADAPTING METHOD

摘要

Provided is a video bandwidth adapting device and adapting method. This device first sets a plurality of network transmission paths according to bit rate settings of an IP camera (IPCam), selects one from the network transmission paths to acquire a video stream provided by the IPCam, then plays the video stream in a streaming playback manner, and afterwards, when it is determined that an average delay during playing of the video stream reaches or exceeds an upper limit, selects a network transmission path corresponding to a bit rate setting whose level is lower than that of the bit rate setting of the video stream, so as to acquire a video stream with a lower-level bit rate setting through the network transmission path.
