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: A system using a dot-reading operating apparatus to operate a TV STB is provided, which includes: a channel-selecting table, the image code which is preset on an object surface printed the channel-selecting table and includes the dot-reading information code, a dot-reading operating apparatus which includes an operating-signal processing module comprising an operating-signal receiving module, an memory module, an operating processor and an operating-signal transmitting module which includes a remote signal receiving module, a remote control memory module, a remote control processor, and a remote signal transmitting module receiving the data signal from the remote control processor and transmitting the data signal. The system can be realized by tiny structure changes or loading software to the dot-reading apparatus and TV STB of prior ate, and the cost is reduced.
