Abstract

The invention discloses a session terminal circuit, a session peripheral circuit and a session system, and particularly relates to the technical field of video sessions. The session terminal circuit comprises a first voltage regulation circuit, a first protocol chip and a first Type C connector; the first protocol chip is electrically connected with a second CC pin of a second protocol chip in the session peripheral circuit through the first CC pin so as to obtain a voltage regulation request of the second protocol chip; the first protocol chip forwards the voltage regulation request to a first voltage regulation circuit, and the first voltage regulation circuit carries out voltage regulation according to the voltage regulation request and outputs regulated voltage through an output voltage end; and the first Type C connector obtains the adjusted voltage and transmits the adjusted voltage to the session peripheral circuit through the voltage output pin. According to the scheme, the protocol chip and the Type C connector can directly transmit the voltage to the peripheral circuit, modules such as a network transformer and a current limiting circuit do not need to be added, and resource consumption of a product is reduced.

Description

Technical field [0001] The present invention relates to a video conversation technologies, and particularly relates to a circuit terminal session, session and conversation system peripheral circuits. Background technique [0002] When implementing a video session, the session in addition to achieving the terminal data processing function other than a video session, through the peripheral device may also be connected to the terminal session, voice or video playback on a video session peripheral device. [0003] When the distance is long conversation terminal and peripheral device, the conference terminal existing products POE (Power OverEthernet) protocol to support data transmission and power output interaction, using twisted-pair UTP cable connection terminals and peripherals. Inside the end product, the need to first adapter input voltage, first raised by a DC-DC Boost (step-up chopper) circuit is required to POE about 54V, and then adding an output of the power limiting circui...
