Abstract

A network telephone device includes a telephone host, a control module, a processing module, an audio/video output unit, and a data reader/writer. The telephone host provides general communication processes of network telephone via the information network. The control module produces recording signal and transmitting signal according to the receiving process and transmission process. The processing module executes the corresponding process of the signals received and transmitted by the telephone host respectively according to the recording signal and transmitting signal produced by the control module. The data reader/writer executes the read/write process from/to the memory unit based on the process result by the processing module, and then the audio/video output unit executes the output process based on the read/write process by the data reader/writer. Therefore, the network telephone device processes and plays audio/video information from different input sources, and thus has enhanced capabilities of multimedia process of network telephone.

Claims

1. A network telephone device applicable to an information network comprising a network telephone operation platform, the network telephone device comprising:

a telephone host connectable with the information network via a network interface, for receiving information transmitted from the information network and/or transmitting received information to the information network;

a control module for generating recording signal and transmitting signal respectively based on the receiving process and transmission process of the telephone host;

a processing module for executing corresponding processes of the signals received and transmitted by the telephone host respectively based on the recording signal and transmitting signal produced by the control module;

an audio/video output unit for outputting the signals processed by the processing module; and

a data reader/writer electrically connected with the telephone host and the processing module via the control module for reading/writing information from/to a memory unit, after receiving the recording signal transmitted from the control module, the data reader/writer saves the signals processed by the processing module in the memory unit, and after receiving the transmitting signal transmitted from the control module, the processing module executes the process of signals read by the data reader/writer from the memory unit, and then transmits the processed signals to the telephone host, and after that, the telephone host transmits the processed signals to the information network via the network interface, wherein, when the communication between the telephone host and the information network is in an idle state and the data reader/writer activates the read action on the memory unit, the processing module executes the process of signals read by the data reader/writer, and after that, the audio/video output unit executes the signal output process.

2. The network telephone device of claim 1, wherein the information network is either of a Public Switched Telephone Network (PSTN) and Ethernet.

3. The network telephone device of claim 1, wherein the telephone host comprises a user interface, whereby a user is allowed to input operation commands, the data reader/writer activating a read action on the memory unit based on the operation commands received by the user interface.

4. The network telephone device of claim 1, wherein the telephone host comprises a user interface, whereby a user is allowed to input operation commands, the telephone host executing the processes of receiving signal and transmitting signal based on the operation commands received by the user interface.

5. The network telephone device of claim 1, wherein the telephone host comprises a central control unit that controls the transmission process of the audio/video information of the network interface and the information network.

6. The network telephone device of claim 1, wherein the control module is a control switch that controls transmitting paths of signals after that being processed by the processing module.

7. The network telephone device of claim 1, wherein the processing module comprises:

an audio processing unit for executing audio compression/decompression and mode conversion processes on the audio information received by the telephone host, and after that, the processed information are outputted by the audio/video output unit and/or saved by the data reader/writer; and

a video processing unit for executing video compression/decompression, mode conversion, and parameter adjustment processes on the video information received by the telephone host, and after that, the processed information is outputted by the audio/video output unit and/or saved by the data reader/writer.

8. The network telephone device of claim 7, wherein first, the processing module determines whether the signals received by the telephone host is in a file mode readable to the network telephone device or not, if not, then the processing module executes the process of mode conversion.

9. The network telephone device of claim 7, wherein the video processing unit executes the video signal process that includes at least:

adjusting the display parameters of display dimension and display resolution.

10. The network telephone device of claim 1, wherein the data reader/writer is a CD-rewritable disk.

11. The network telephone device of claim 10, wherein, the CD-rewritable disk supports at least one kind of the video compact discs, such as DVD, SVCD, DVCD, VCD, CD-R(W), DVD-R, CD-G, and JPEG etc.

12. The network telephone device of claim 10, wherein the CD-rewritable disk supports at least one member of the audio compression mode assembly of MPEG, AC3, DTS, WMA, and AAC.
