Abstract: Method and device for transmitting media stream are provided to solve the problem of quality reduction in audio and video caused by packet loss, jitter, link breakage in a media stream transmission process in the conventional art. The method includes: a media capability negotiation between a calling terminal and a called terminal is conducted according to a link establishment request message transmitted by the calling terminal and a response message transmitted by the called terminal in response to the link establishment request message, and at least two media channels are established; a media stream is transmitted through a first media channel according to negotiated media capabilities; and when an abnormity is detected to appear in the media stream transmission of the first media channel, another one of the at least two media channels is selected as a second media channel, and the media stream is switched from the first media channel to the second media channel for transmission. By the invention, the quality of audio and video of two communicating parties can be ensured.

Abstract: An intelligent monitoring terminal and a video monitoring method are disclosed. The intelligent monitoring terminal comprises: an acquiring component, configured to acquire video data; a monitoring component, configured to monitor whether an object enters a monitoring range or not, and send a monitoring result to a controlling component; and the controlling component, configured to, when the monitoring component determines that an object enters the monitoring range, control the acquiring component to aim at the monitored object, acquire a video image of the object, and control a warning component to give an alarm. The intelligent monitoring terminal of the disclosure is controlled by a monitoring controller in a normal condition, independently processes an unexpected event in the case of emergency, solves the defect existing in current monitoring terminals, greatly enhances the capabilities such as monitoring, protection, forensics thereof, and exerts the protected, and value maximization is realized.
