A video playback method is provided. According to the method, a frame before requested video playback time is transmitted and received without speed limitation to perform decoding without video play back, and a frame after the video playback time is transmitted and received in accordance with playback speed to perform decoding and video playback, thereby quickly playing back a video in accordance with video playback time requested by a user without changing Group Of Video (GOV) setting or codec setting.

Method and apparatus for playing back video in accordance with requested video playback time

A real-time video streaming method between a server and a client according to a real-time transport protocol (RTP)/real-time streaming protocol (RTSP) standard protocol, including transmitting a DESCRIBE command including a Require header from a client to a server, wherein the client and the server support the Require header, receiving session description protocol (SDP) information from the server in response to the DESCRIBE command, receiving, at the client, a video from the server according to the RTP/RTSP standard protocol, in response to an encoding attribute of the video transmitted from the server to the client being changed, describing a changed encoding attribute in an RTP extension header of an RTP packet when the RTP packet is first transmitted in an RTP payload type determined according to the changed encoding attribute, and changing, at the client, a decoding setup based on the changed encoding attribute in the RTP extension header.

Method and device for media streaming between server and client using RTP/RTSP standard protocol

Provided is a network security system including: a spatial information collector configured to acquire, from a manager input terminal, spatial information; a device position receiver configured to receive, from the manager terminal, at least one device installation position with respect to the spatial information and storing the at least one device installation position; a device recommender configured to provide a candidate device list corresponding to the at least one device installation position; a device determiner configured to receive a signal for selecting at least one device from the candidate device list, and determine a model of the at least one selected device to be installed at the at least one device installation position; and a device setter configured to set a setting of the at least one selected device.
