1. A device for switching a frame and inputting a command via network, comprising:
- a display unit;
an input unit used to input a control command;
a plurality of far-end computers each having a connection program and/or a control program, said connection program being used to encode and packet a displayed frame of into a pixel data, said control program being used to transfer a control command generated by an input end of one of the far-end computers operated by the user; and
a module unit connected to the far-end computers via network and also connected to said input unit and said display unit, said module unit being used to receive the control command issued by said input unit or said input end and transfer a processed real-time frame to said display unit, or to store the displayed frame as a history frame;
or to switch a frame.

Abstract
The present invention provides a device for switching frame and inputting command via network transmission. The device is connected to a plurality of far-end computers via network so that a user can select and switch frame by using control commands of an input unit, or can issue control commands via network by using a far-end control program, thereby transferring the received real-time frame of a far-end computer to a display unit.

9. A device for switching a frame and inputting a command via the packet based digital network transmission, said device receiving a control command of an input unit to switch a frame of a far-end computer, or transferring the frame of said far-end computer to a display unit, said device being capable of storing the frame as a history frame, and switching the frame, said device comprising:
-
a microprocessor connected to said input unit and used as a control center of said module unit;
a first memory element connected to said microprocessor;
a network interface controller connected to said microprocessor and also connected to said far-end computers via network;
a second memory element connected to said microprocessor and said network interface controller and used for storing a real-time pixel data;
a frame buffer connected to said microprocessor and said second memory element and used for converting the real-time pixel data in said second memory element into the frame data, said frame buffer being capable of putting the frame data into said first memory element or said second memory element as the history frame; and
a video conversion controller connected to said microprocessor and said frame buffer and used for accessing the frame data of said frame buffer and converting he frame data into an analog or a digital video signal for outputting to said display unit. - View Dependent Claims (10, 11, 12, 13, 14)
