The present invention relates to a home network video phone system equipped with a print server and a hard disk server function. In particular, the home server includes a server and a hard disk server function as a home network terminal, and a printer server having a part of a home server function in addition to a visitor confirmation function. It relates to a home network video phone system equipped with a hard disk server function.

Due to the current spread of personal PCs and low prices of PCs, there is a tendency to have a plurality of computers in a general home, and there is a waste of cost in having a printer for each computer.

Also, in case of sharing and using the printer by connecting to a specific PC, the PC connecting the printer should always be powered on, otherwise, the trouble of having to turn on the PC directly connected to the printer in order to use the printer. This had its drawbacks.

1 is a view showing the configuration of a conventional video phone system.

As shown in FIG. 1, the conventional videophone system is a videophone system used in a narrowband digital network, and has VME bus means 21 used as a system bus for control communication and synchronization functions between modules. A pre / post processor 22 and a pre / post processor 22 which are connected to the VME bus unit 21 to process input signals from the camera to convert to a standard video format or to display decoded images on a TV monitor. Frame memory device 23 for storing an image converted into a standard format, a source codec device 25 composed of a plurality of processing elements (PE) for image encoding and decoding, and the VME bus means. A common memory device 24 which is a message storage function for synchronization and communication between the host and the processing element or between the processing element and the processing element, and the VME bus means 21. After correcting the forward error of the encoded video data, the network connection device 27 for creating a frame structure and the reverse function for connecting to the integrated information communication network, and the frame memory device 23, the source codec device. (25), connected to the network connection device (27) and the common memory device (24) and composed of image bus means (28) for moving high-speed video data.

In detail, it is as follows.

21 is a VME bus, 22 is an A / D and D / A converter, 23 is a network connection, 24 is a common memory section, 25 is a source codec section, 26 is a TX / RX buffer And 27 denote network connections and 28 denote image buses.

The VME bus 21 is used as a system bus for control communication and synchronization functions between modules. The A / D and D / A converters 22 perform low-band filtering, color signal separation, and interpolation of NTSC synthesized or component signals. ), And a function of converting to CCITT standard video format and its inverse conversion function through the process of decay, etc.

Directly connected to the A / D and D / A converter 22 and the frame memory unit 23, the 8-bit contrast information signal and the 8-bit signal are provided by the horizontal and vertical synchronization signals, the data valid time display signal, and the clock signal. The first and second color difference signals are mainly received.

The frame memory unit 23 serves to store input / output image information. The common memory section 24 is located between the VME bus 21 used as the system bus and the high speed image bus 28 used as the image data path, and is located between the processing element PE and the host CPU and the processing element PE. It is used as a storage place for data transmission between the processing element and the PE, and is required to efficiently communicate with the entire system controller (host VPU).

The source codec unit 25 including a plurality of processing elements PEL ... PEN is connected to the common memory unit 24 and the image bus 28 to convert the input image converted by the A / D and D / A converters 22. It reduces the video information by using the video compression algorithm, the TX / RX buffer 26 is the video information or network connection is reduced from the source codec section 25 from the VME bus 21 or the image bus 28 The video data obtained in step 27 is temporarily stored.

The TX / RX buffer 26 is connected to the network connection unit 27 to transmit and receive the reduced video information by one bit unit.

After the network connection unit 27 corrects an error of encoded video data, the network connection unit 27 synthesizes a video signal, an audio signal, and other data to connect to an integrated information communication network (ISDN). Functions that make and perform the reverse function.

The image bus 28 is used for moving the high speed image data, and is used to transfer the image data to frame memory 23 in units of 8 bits, or to perform a bus and arbitration function between processing elements.

The processing elements constituting the source codec unit 25 are modules incorporating a digital signal processing chip, and divide an image code or a decoding function into subfunctions to process one processing element or one subfunction. do.

The input data may be input from the frame memory unit 23, the common memory unit 24, or the previous stage processing element in the pipeline structure, and the processing result may be transferred to the next stage processing element in the pipeline structure. Or through the common memory 24 to transfer to non-contiguous processing elements.

The final image information reduced by the processing elements is sent to the TX buffer 26 and transmitted to the network connection 27. The image decoding unit receives the input data from the RX buffer 26 and performs a decoding function, and transmits the result to the frame memory unit 23.

However, the conventional videophone system constructed and operated as described above has a disadvantage in that it is impossible to realize a home network videophone system equipped with a printer server and a hard disk server function having a part of the home server function in addition to the visitor confirmation function. .
