    摘要： The disclosure discloses a method and a system for switching a working mode for a backward compatible broadband wireless network, in order to solve the technical problem of switching between each working mode when various compatible modes based on different channelized sets exist in the broadband wireless network. In the disclosure, an access point (AP) indicates its current working mode by a system configuration message; the AP instructs a non-AP associated with the AP to switch a working mode by a mode switching message or a frame exchange sequence; and the non-AP switches the working mode according to instruction information included in the mode switching message or the frame exchange sequence after receiving the mode switching message or the frame exchange sequence. Through the scheme of the disclosure, a wireless point can be switched between each working mode when various compatible modes based on different channelized sets exist in the broadband wireless network, thereby setting up a broadband wireless network supporting backward compatibility.

    摘要： A media transmission method based on telepresence is disclosed, comprising: during connection establishment, a master telepresence terminal of a local media transmission system and a remote endpoint perform signaling exchange, to establish a media logical channel between the local media transmission system and the remote endpoint; and transmits the same type of media streams between the local media transmission system and the remote endpoint through a media logical channel or respectively through multiple media logical channels, and receives the same type of media streams through a media logical channel or respectively through multiple media logical channels. A media transmission system based on telepresence is further disclosed correspondingly. Through the disclosure, when a telepresence system of a certain conference site is called, only one number needs to be called, which is easy to operate; moreover, agent information exchange can be performed in the telepresence system, thereby achieving the effect of sound-based localization, solving the problem such as synchronization between streams, and improving user experience.
