Abstract: A point-reading device for obtaining network audio/video files includes an image reading unit for obtaining image codes including information codes representing audio/video target files. A digital processing unit connected with the image reading unit receives the image codes sent from the image reading unit and decodes the image codes to obtain the information codes representing the audio/video target files. A memory for storing data, connected with the digital processing unit stores an information table that identifies the corresponding relationships between the information codes representing the audio/video target files and attribute information used for obtaining the audio/video target files. A network module establishes a connection between the digital processing unit and a network server. An operation system supporting network protocol is provided in the digital processing unit.

Abstract: The present invention discloses a video player, comprising a decoding and control unit for outputting decoded video and audio signals; a storing unit for storing an application software capable of working without starting a computer operation system; a video processing unit for processing decoded video signals outputted by the decoding and control unit; an audio processing unit for processing decoded audio signals outputted by the decoding and control unit; an Optical disc driver's multi-use control circuit for multi-use controlling a DVD Optical disc driver of the computer; and a switch unit for switching the video processing unit and the audio processing unit to be coupled to the display and the sound box after monitoring a shut-off signal of the computer, and in the meantime switching two outputs of DC power to the video player.
