The invention discloses a network penetrating method and system of intelligent TV private cloud equipment; the method comprises the following steps: a mobile terminal starts an access request to intelligent TV private cloud equipment, and searches gateway supported network type and equipment network address data of the intelligent TV private cloud equipment from a cloud server; if a gateway supported UPNP protocol of the intelligent TV private cloud equipment is detected, the mobile terminal can use the equipment network address data to access the intelligent TV private cloud equipment through the UPNP protocol; if the gateway of the intelligent TV private cloud equipment does not support the UPNP protocol, the mobile terminal uses a P2P agent to access the intelligent TV private cloud equipment. The method and system can use an external network to access and manage the home intelligent TV private cloud equipment without changing existing network hardware facilities of a normal user, and can ensure the network transmission efficiency in a maximum level, thus improving transmission efficiency.
