Relay device and method causing a switching destination terminal to perform a smooth data output corresponding to a processing capacity of the switching destination terminal at the time of switching between terminals
Abstract:
A relay device (40) comprises: an NW interface (408) for making a connection with a switching source terminal (20) that is receiving media data transmitted from a media server (10) and with a switching destination terminal (30); an information storage (403) for storing a media data processing capacity of the switching source terminal (20) and switching destination terminal (30); a media controller (401) for making a transmission request to the media server (10) for media data corresponding to the above processing capacity in the information storage (403), and for acquiring the above processing capacity of the switching destination terminal (30) from the information storage (403) and instructing to transfer the media data corresponding to the acquired processing capacity to the switching destination terminal (30); a media receiver (404) for receiving the media data transmitted from the media server (10); a media buffer (405) for holding the media data; and a media transmitter (406) for acquiring from the media buffer (405) the media data corresponding to the processing capacity of the switching destination terminal (30) and transferring it to the switching destination terminal (30).
Abstract(Chinese):

中继装置（40）包括：NW接口（408），用于与正在接收从媒体服务器（10）和转交目的地终端（30）发送的媒体数据的切换源终端（20）建立连接; 用于存储切换源终端（20）和切换目的地终端（30）的媒体数据处理能力的信息存储（403）。 用于向所述媒体服务器（10）发送与所述信息存储器（403）中的上述处理能力对应的媒体数据的传输请求并且用于获取所述切换目的地终端（30）的上述处理能力的媒体控制器（401） 从所述信息存储器（403）发送指示将所获取的处理能力对应的媒体数据传送到切换目的地终端（30）; 媒体接收器（404），用于接收从媒体服务器（10）发送的媒体数据; 用于保存媒体数据的媒体缓冲器（405）; 以及媒体发送器（406），用于从媒体缓冲器（405）获取与切换目的地终端（30）的处理能力对应的媒体数据并将其传送到切换目的地终端（30）。
