Description

Recording device of Internet data

The present invention relates to a recording apparatus of Internet data, and more particularly, after searching by recording the above-mentioned information as an analog video signal while browsing various text and image information provided from the Internet. The present invention relates to a recording apparatus for internet data that allows a user to easily view the searched contents at any time.

Today, the demand for information is soaring enough to be called the information age, and access to the Internet, which is likened to a sea of information, to acquire necessary information and enjoy entertainment is becoming more common. In particular, access to and use of the World Wide Web (WWW) (hereinafter referred to as the “web”) that supports images, music, or motion pictures other than texts is booming.

However, such Internet use is mainly performed using a personal computer (PC) or a recently developed Internet television (TV). The process of searching for necessary data on the Internet requires a lot of effort and time. In addition, especially when accessing the web and receiving information, relatively much more data has to be received. If the desired information or video cannot be found, the searched content must be re-searched to confirm the received information in more detail. In such a case, a considerable communication cost is required, and if the language provided on the Internet is not Korean, it takes more time to read the received data even when there is no transmission and reception of data, thereby incurring unnecessary communication costs. There was a problem.

In order to reduce the reading time of Internet data in the absence of communication, the data is stored in the form of received digital data without reading the data in the communication connection state, and then all the desired sites are searched for communication. A method of disconnecting and reading stored data has been proposed and is currently in use. However, the above method has to occupy the storage space of digital data inefficiently in case of long-term storage such as the case of intermittent reference data as well as the problem of storing huge digital data, and thus There is also a problem that reduces the search efficiency.

Accordingly, an object of the present invention is to provide a recording apparatus for internet data, which has been created to solve the above problems and changes the recorded contents into analog broadcast signals and records them by searching the Internet.

Another object of the present invention is to provide an apparatus for recording Internet data capable of recording data including moving image data.

It is still another object of the present invention to provide an apparatus for recording internet data which stops recording so that the recording medium is not used unnecessarily when information is stopped.

Fig. 1 shows the configuration of an embodiment of a recording apparatus for internet data according to the present invention.

Hereinafter, the configuration and operation of an embodiment of an apparatus for recording Internet data according to the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a configuration of an embodiment of an apparatus for recording internet data according to the present invention, comprising: a modem 10 for connecting to a communication network and transmitting and receiving data; An image memory 20 having a storage space corresponding one-to-one with pixels of an image screen; A RAM DAC (RAM DAC: RAM Digital / Analog Converter) for converting each scanned data into three primary color (RGB) signals while continuously and repeatedly scanning data stored in the image memory 20; An NTSC encoder (32) for converting three primary color signals output from the RAM (31) into NTSC signals as broadcast signals; A luminance / chromatic signal processor 51 for separating the luminance signal from the color signal and performing input signal processing on the cassette tape to record the converted NTSC signal on the cassette tape; A deck unit 52 for controlling the operation of the cassette tape and the phase of the head drum, respectively; and the servo unit 53; Main memory (40) for temporarily storing digital data received from the modem (10); An input unit 90 for inputting a user's selection; And a central processing unit 60 for controlling the operation of the components, converting the received data into pixel data, moving the image data to an appropriate position of the image memory 20, and processing a user's requirements through the input unit 90. It is configured to include.

Hereinafter, the operation of an embodiment of the recording apparatus of the Internet data according to the present invention will be described in detail with reference to the configuration diagram of FIG.

First, when a user requests an Internet connection through the input unit 90, the CPU 60 controls the modem 10 to provide an Internet service through a communication network (not shown). Require connection. When the connection to the server is completed and a site with the desired information is established through the server, the data is recorded as an analog video signal through the following process.

The digital data received from the modem 10 is read by the central processing unit 60, respectively, and the type of the data and the relative position within the received page (except for the difference between the page and the absolute screen size). Almost identical to the position to be displayed on the screen), and the received data is converted into pixel data based on the output resolution and number of colors currently set in the device according to the interpreted contents. The memory address corresponding to the position to be displayed at "

Apart from this writing process, the RAMDAC 31 continuously and repeatedly scans the image memory 20, and converts pixel data in each address into three primary colors (RGB) signals. The output of the converted signal is output in synchronization with the pixel clock, which is a sync clock for displaying the signal on the screen. In addition, when there is a need to change the color of the scanned pixel data, the palette for the same pixel data may be changed according to the control signal of the CPU 60. The three-color signal output from the RAMDAC 31 is a signal that can be immediately expressed as an image when applied to an external display device such as a monitor, and the user can select a desired input by using the output image. .

The three primary color signals output from the RAMDAC 31 are input to the NTSC encoder 32. The NTSC encoder 32 converts the input three primary color signals into an NTSC signal which is one of broadcast signals. The horizontal synchronous signal H-sync and the vertical synchronous signal V-sync synchronized to the pixel clock are inserted into the NTSC video signal converted when necessary.

Accordingly, the signal output from the NTSC encoder 32 becomes an analog broadcast signal that can be immediately expressed as an image when applied to an external display device such as a television.

The NTSC signal output from the NTSC encoder 32 is divided into a luminance signal and a color signal by the luminance / chromatic signal processing unit 51 in the recording unit 50, and each of the signals divided into frequency (FM) modulation and low frequency. It is converted into a signal, mixed again, and then inputted to a video head, thereby enabling recording as an analog video signal on a magnetic tape. In fact, recording of Internet data is performed by the central processing unit 60 through the deck unit 52. The tape is placed in the recording position, and the servo unit 53 controls the driving of the cassette tape and the phase of the head drum. In this way, the recorded Internet data information can be reproduced in a normal VCR at any time as necessary and read by the user as a video signal.

In addition, the central processing unit 60 temporarily stores the Internet data received from the modem 10 in the main memory 40 via a data bus. The central processing unit 60 reads the change information (the number of images and the change time intervals, etc.) for each image of the data to be changed, and stores the change information in the image memory 20 corresponding to the pixels in which the image is to be expressed. The changed image is recorded at every change time interval at the location. After all the images are recorded, the changed image is repeatedly recorded from the beginning. As such, when the recording is repeatedly performed, the moving image signal is output through the RAMDAC 31 and the NTSC encoder 32, and thus the moving image signal is recorded under the control of the CPU 60. The recording is made in the unit 50.

On the other hand, if the connection is released due to unexpected line failure or server failure during the recording process as described above, the modem 10 detects such disconnection and notifies the central processing unit 60 thereof. . When the central processing unit 60 is notified of the disconnection, the central control unit 60 controls the servo unit 53 to stop running of the cassette tape, and simultaneously controls the deck unit 52 to stop the cassette tape instead of the recording position. It will return to the position and stop recording. In addition to the above disconnection, the central processing unit 60 controls the deck unit 52 and the servo unit 53 to stop the recording operation even when no data is received from the modem 10 for a long time. do.

The Internet data recording apparatus according to the present invention configured and operated as described above efficiently records characters and video information whose capacity is too large to be stored as digital data by recording information provided from the Internet as an analog video signal on a cassette tape. It is useful and convenient because it can be recorded and stored at any time, so that it can be played at any time and searched for the information you want, and you can read the information off-line without reading the information on-line. In addition to reducing the communication cost by significantly reducing the time occupying the communication line, the use of the apparatus according to the present invention can be used because the storage of data is limited to the time length of the recording medium irrespective of the amount of data provided. As much time as you want, at the time you want It is a very useful and economical invention that can be scheduled and recorded.
