The method comprises the following steps of: before the access point is automatically connected, acquiring access point information of last successful connection from an access point information pool after the access point information is acquired, automatically connecting the access point of the last successful connection after the automatic connection is successful, automatically accessing the access point of the last successful connection, otherwise, when the automatic connection fails, canceling automatic trial of connecting other access points, meanwhile switching the connection to a manual connection mode, and executing the following operations: performing information matching on information of a target access point in an encryption state and all access point information in the access point information pool one by one, wherein when the matching is successful, the access point corresponding to the successfully matched access point information in the access point information pool is used as the target access point. Abstract: The invention discloses an audio and video integrated control circuit and a method for accessing an access point.
