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.

主权项

1. A video bandwidth adapting device, connected to an IP camera (IPCam), wherein the IPCam comprises a plurality of bit rate settings, and the video bandwidth adapting device comprises:
a network unit; a detection unit, connected to a playing unit, and used to detect an average delay when the playing unit plays a video stream; and a computing unit, connected to the network unit, the detection unit and the playing unit, and used to: upon being connected to the IPCam by using the network unit, establish a plurality of corresponding network transmission paths according to the bit rate settings; select one from the network transmission paths to acquire a video stream provided by the IPCam, so that the playing unit plays the video stream in a streaming manner; and upon knowing that the average delay during playing of the video stream and detected by the detection unit reaches or exceeds an upper limit, select 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.
