    Abstract: Embodiments of this application relate to a login method based on fingerprint recognition and a device. The method includes: collecting fingerprint data when a power-on signal is detected; matching the fingerprint data with preset fingerprint data that is prestored; and logging in to a terminal device if the matching succeeds. According to the login method based on fingerprint recognition and the device provided in this application, not only terminal device login efficiency can be improved, but also a battery life of the terminal device can be increased.

    Abstract: 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.

    Abstract: 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.
