Abstract: A set top box transmits a connection request to a TV to request a number of response signals therefrom. The response signals are read when the TV is in a working state, and an idle signal is output if the response signals are not read in a predetermined time. State of the TV is determined according to the response signals or the idle signal, and the set top box is controlled to be in the working state according to the starting signal, or placed a sleeping/standby state according to the standby signal.

Abstract: A method for promptly redialing a broadband access server is disclosed. The method includes: sending a PPPoE Active Discovery Terminate (PADT) packet to a BAS from a client computer upon the condition that the client computer has been abnormally disconnected from the broadband access server (BAS), sending a responsive PADT packet to the client computer if the client computer is allowed to perform the prompt redial. The method further includes: sending a PPPoE Active Discovery Initiation (PADI) packet to the BAS from the client computer, sending a PPPoE Active Discovery Offer (PADO) packet to the client computer, sending a PPPoE Active Discovery Request (PADR) packet to the BAS from the client computer, sending a PPPoE Active Discovery Confirmation (PADS) packet to the client computer from the BAS so as to create a new connection between the client computer and the BAS.
