33, 34, and 35 are a first memory, a second memory, and a third memory constituting the image information processing means of the present invention, wherein the first memory 33 is the image information provided from the image information server 31; (This is written by HTML software) is a ROM to which a program (i.e., web browser software) for analyzing is registered, and the second memory 34 temporarily stores image information interpreted in the first memory 33. A third memory 35 is a video RAM in which the analyzed image information is mapped (R / G / B pixel data) in a form displayed on the television CRT apparatus (17 in FIG. 1).

36 is an IF conversion process performed by the video IF module 15 to separate the horizontal synchronous signal HS and the vertical synchronous signal VS from the television video signal applied to the video signal processor 16 to the video RAM 35. A synchronization signal detection unit to be applied as a synchronization signal for screen display configured in the following.

Next, the operation of the Internet connection apparatus for television according to the present invention having the above-described configuration will be described in detail with reference to the flowchart shown in FIG.

First, when the control unit 11 inputs a control signal for setting the function in the remote controller 10 while waiting for the function setting by the remote controller 10 while the power of the corresponding television is turned on in step 50, In step 52, the control unit 11 determines whether the control signal is a signal for setting the internet mode. If the control signal is not a control signal for setting the internet mode, the control unit 11 proceeds to step 54. The normal television broadcast signal described by reference is performed.

In this case, the video signal subjected to IF conversion processing by the video IF module 15 is processed by the video signal processor 16 to be output from the television CRT apparatus 17 through the video switching unit 39.

On the other hand, if it is determined in step 52 that the control signal is a signal for setting the internet mode, in step 56 the control unit 11 applies a control signal for setting the internet mode to the microprocessor 30, Accordingly, the microprocessor 30 applies the image switching control signal SW to the image switching unit 39, thereby setting a processing path for the image information under the Internet mode.

The selected video information is received through the module 32 and stored in the RAM 34 as the second memory. The video information stored in the RAM 34 is interpreted by a program (web browser software) registered in the first memory (ROM) 33 and mapped to the video RAM 35 which is the third memory.

Subsequently, the image information (R / G / B pixel data) mapped to the video RAM 35 is generated by the horizontal / vertical synchronization signal (HS / VS) obtained from the television image signal by the synchronization signal detector 36. The image data conversion unit 37 reads out the image data conversion unit 37 and converts the image data into a form that can be displayed on the television CRT device 17. In other words, the image information mapped to the video RAM 35 is generated based on the horizontal / vertical synchronization signal (HS / VS) of the television image signal detected by the synchronization signal detector 36. As a result of reading out by the clock signal at < RTI ID = 0.0 > 1), < / RTI >

The image information signal from the image data converter 37 is converted into an analog signal by the digital-analog converter 38 in step 60 and then the image signal processor 16 is transmitted through the image switcher 39. It is applied to the television CRT apparatus 17 to be reproduced.

Then, the controller 11 determines whether the input power for hard copy output from the remote controller 10 is input (step 62), and if no hard copy is commanded from the remote controller 10, returns to the initial stage. On the other hand, when a hard copy command is input from the remote controller 10, under the control of the controller 11, the microprocessor 30 receives the image information signal stored in the second memory 34 in step 64. The interface 40 is applied to the printer 41 to be applied and output.

As described above, according to the Internet connection apparatus for television according to the present invention, the Internet connection of the television to the video information server is possible, and thus the video information provided from the video information server can be reproduced on the CRT device of the television.
