A fingerprint recognition method and terminal device provide authentication by simultaneously collecting fingerprint data when a power-on signal is detected, attempting to match the fingerprint data with preset fingerprint data, and logging in to the terminal device proceeds when the matching succeeds.

Login method based on fingerprint recognition and device

A fingerprint recognition device having a login circuit is provided in a terminal apparatus. A power button is configured to interwork with a contact, wherein a contact closing stroke of the power button is less than a maximum stroke of the power button. A fingerprint collection circuit is disposed on the power button and a power control circuit is coupled to the power button and configured to control power output to supply power to the fingerprint collection circuit when detecting that the power button is pressed. The power control circuit also controls power output to supply power to the fingerprint collection circuit when detecting that the contact is closed. The fingerprint collection circuit is configured to collect fingerprint data and send the fingerprint data to a fingerprint recognition circuit configured to receive the fingerprint data from the fingerprint collection circuit and match the fingerprint data with preset fingerprint data. The login circuit is configured to log in to the terminal device when the fingerprint data match with the preset fingerprint data.

The present invention discloses a signal display output method, apparatus and system, which pertain to the field of computer technologies. The method includes: receiving, by a TV box expansion device, a radio television signal by using a radio frequency port; performing, by the TV box expansion device, demodulation processing on the radio television signal to obtain a to-be-decoded digital signal; and sending, by the TV box expansion device, the to-be-decoded digital signal to an IP TV box, so that the IP TV box performs decoding processing on the to-be-decoded digital signal to obtain the decoded digital signal for display output. Use flexibility of the IP TV box can be improved by using the present invention.

Signal display output method, apparatus, and system

A method for determining a type of video signal to be output is provided. The method includes: respectively extracting detection signals in video signals in different video output interface modes; respectively converting the extracted detection signal into a direct current voltage signal; and respectively comparing the direct current voltage signal with a voltage threshold, and determining, according to a comparison result, a type of video signal to be output. An embodiment further provides an apparatus for determining a type of video signal to be output. The embodiments of the present invention, by respectively extracting a detection signal included in a video signal in each video output interface mode, and comparing a voltage of the detection signal with a voltage threshold, determine whether a corresponding DAC port in the each video output interface mode is connected to a load terminal, and thereby determine a video signal to be output.
