Description of drawings
For further specifying concrete technology contents of the present invention, below in conjunction with embodiment and accompanying drawing describes in detail as after, wherein:
Fig. 1 is a known television set and a multimedia computer connection diagram.
Fig. 2 is the calcspar of the digital television of tool transmitting function of the present invention.
Fig. 3 is the digital television and a multimedia computer connection diagram of tool transmitting function of the present invention.
Embodiment
In the present invention, provide a kind of digital television with transmitting function.This digital television is by the button of a button on the panel or an infrared remote controller, and when the audio-visual storage output order of input one, this digital television is encoded to audiovisual materials stream, and flowed by the audiovisual materials that this output/input jockey is exported this coding.
As shown in Figure 2, it is the calcspar of the digital television 200 of tool transmitting function of the present invention, comprises a digital TV tuner 210, a Digital Television controller 220, a command input device 230, an output/input jockey 240, a screen 250.
This digital TV tuner 210 is in order to receive a digital television signal, so that it demodulation is produced a transmission stream (transport stream).This transmission stream can be MPEG2 transmission stream, MPEG4 transmission stream or transmission stream H.264.
This Digital Television controller 220 is coupled to this digital TV tuner 210, and this Digital Television controller 220 comprises decoding 221 devices and an encoder 222.This Digital Television controller 220 receives this transmission stream, and by 221 pairs of this transmission stream decodings of this decoder, and export a decoding video-audio data stream.This screen 250 is coupled to this Digital Television controller, in order to show this decoding audiovisual materials stream.This screen 250 can be liquid crystal panel (LCD PANEL) or negative electrode display tube (CRT).
This command input device 230 is coupled to this Digital Television controller 220, in order to receive an instruction.This command input device 230 can be the button on the panel that is arranged at this digital television 200.This command input device 230 also can be an infrared receiver, with receive that an infrared remote controller transmitted instruction.
