FIG. 2 is a diagram showing an example in which a specific still image, that is, a photographic image screen, is divided into a plurality of divided regions in the external image data transmission system. FIGS. 3 to 5 are diagrams each showing a first, Lt; th > transmission data.

FIG. 6 is a block diagram of a data processing apparatus for receiving an unmodulated high-definition still picture broadcast according to the present invention, and FIG. 7 is a detailed block diagram of a data processing apparatus for receiving an unmodified high-definition still picture broadcast according to the present invention.

Hereinafter, a data processing apparatus for receiving an unmodulated high-definition still picture broadcast according to the present invention will be described in detail with reference to FIG. 1 to FIG.

In recent years, display technology has been upgraded to Ultra-HD (3840 * 1080) resolution, which is four times higher resolution / pixel than Full-HD, beyond the full-HD (1920 * 1080) 2160) commercialization technology.

The radical development of such a display technology has brought about a change in high-quality image data, in particular, high-quality still picture data processing and transmission techniques, in an external video data transmission system for transmitting video data output from a display.

In this case, in order to provide a corresponding high-quality screen using a high-resolution-resolution Ultra-HD class display, a moving picture transmission method that relies on a conventional high-rate compression technique is not capable of providing a high- It is replaced by sending. When the external image data transmission system is to transmit a still image, that is, photo data, the high-capacity high-quality data is transmitted as it is from the original uncompressed original, or the high-quality high- , Such high-capacity high-quality still picture data is capable of outputting a plurality of identical still picture data instead of one data even when the still picture data for one specific screen is transmitted in order to output a high-quality picture of the highest quality to the display for high picture quality It would be preferable to send out.

This is because the still image data for the high-capacity high-quality original video data is transmitted as it is without compressing the video data, or the high-capacity data is transmitted to the destination to which the display is connected by adopting a compression method in which the original is not changed. Even if the high-quality still picture data is sent out by the external video data transmission system, even if the high-quality / high-picture still picture data Even if a display capable of outputting a still image is provided, only a still image distorted in a fine portion due to data modulation or damage generated in the transmission process is output from the display.

That is, in the case of transmitting only the still picture data of a large capacity and high picture quality for the specific one picture, the above-mentioned problems such as data corruption frequently occur when a picture of a certain level or more can not be provided regardless of the performance of the display .

That is, existing video transmission broadcasting based on image data compression technology with deterioration in image quality does not satisfy the function of a large-capacity display device, and thus a static image transmission broadcasting without deterioration in image quality is required. A data processing apparatus for receiving an unmodulated high-definition still picture broadcasting according to the present invention will be required.

Therefore, according to the provision of a display capable of outputting a still image of high picture quality / high picture, etc., in the external video data transmission system for transmitting a still picture or the like, when transmitting still picture data for a specific one picture, It is necessary to transmit the still image data of the external video data transmission system so that the plural pieces of still image data are processed so as to include the page information as the unique code and then transmitted. It is designed.

That is, the data processing apparatus 200 for an unmodulated high-definition still picture broadcasting according to the present invention is pre-processed in an external video data transmission system so that page information, which is a unique code, is included as a plurality of identical still picture data for a specific screen It is assumed that a plurality of transmitted still image data are inputted.

The plurality of pieces of still picture data may be sent out in two or three or more, but in some cases, only one piece of still picture data may be transmitted.

In the present specification and drawings, for convenience of description, three still picture data are transmitted as a plurality of still picture data in the external video data transmission system for one specific picture.

The data processing apparatus 200 for an unmodulated high-definition still picture broadcasting according to the present invention includes an input terminal 210 for inputting the transmitted plurality of still image data, a high-definition still image data management module 220, a memory And an output terminal 240 for outputting still image data sent to the display 300 side.

The high definition still image data management module 220 acquires page information included in each of the inputted still image data when a plurality of pieces of still image data related to one specific screen are inputted through the input terminal 210, And maps the storage space of the memory 230 according to the obtained page information.

That is, the high-definition still image data management module 220 has memory pages 231, 232, and 233 to which the page numbers corresponding to the page information are assigned to the input still image data, The page mapping of the storage space of the memory 230 is performed.

For example, in the external image data transmission system, three pieces of still image data for the same still image are transmitted and input. One page information is 1, the other page information is 2, and the other page information The high definition still image data management module 220 causes three memory pages to be formed in the storage space of the memory 230. One of them is allocated page number 1 and the other is allocated page number 2, and the other page number 3 is allocated.

Then, the high-definition still image data management module 220 stores each of the inputted still image data in a memory page to which a page number corresponding to the corresponding page information is allocated among the storage spaces of the memory.

That is, the still image data of the page information 1 is stored in the memory page to which the page number 1 is allocated, the still image data of the page information 2 is stored in the memory page to which the page number 2 is allocated, Image data is stored in the memory page to which the page number 3 is assigned.

In other words, still image data stored in the memory pages of the page numbers 1, 2, and 3 are still image data including page information 1, page information 2, and page information 3, And data processed and transmitted as the same still image data for a specific screen in the video data transmission system.

However, as described above, each still image data stored in each memory page may include data in which distortion has occurred in a data compression process and / or a data transmission process.

The high definition still image data management module 220 superimposes the still image data stored in each of the memory pages when the transmission end signal for the screen is inputted and outputs the superimposed data to the display side through the output terminal 240 . Only the data of the non-lost block is superimposed to constitute a single original photograph and output it to the display. That is, at this time, the data superimposition causes the data of a certain damaged segment of one memory page to be overlapped with the data of the non-damaged segment of another memory page, thereby generating one undamaged superimposed still image data.

That is, even if data corruption occurs in a part of one or more still image data among the same still image data for the same screen stored in each memory page, the high-quality still image data management module 220 determines that three still images In the case where not only the damage to the same part occurs in all of the data, the data superimposed data is reproduced as complete still image data free from data distortion, and the still image data of high quality and high capacity is displayed through the display of image quality So that it can be output with a full quality.

Through the function of acquiring page information of the above-described high-quality still image data management module, performing high-quality still image data management from the page mapping to the storage space of the memory to superimposed data output after data superimposition, The transmission signal for the still picture data of the normal picture quality as well as the still picture data of the high capacity high picture quality is output to the display in a complete state without any damage.

Header information is included in the still picture data transmitted from the external video data transmission system.

At this time, when the still image data to be transmitted is processed in advance so as to include the page information in the header information, high-resolution information indicating that the still image data is large-capacity high- .

That is, the header information of each of the still image data transmitted from the external image data transmission system includes the page information, processed in advance so as to include high-resolution information indicating whether it is still image data of a large capacity and high image quality, do.

At this time, the high-definition still image data management module 220 makes only the still image data including the high-resolution image information in the header information of the inputted still image data to be subjected to the high-definition still image processing function, Are output to the display side through the output terminal 240 in accordance with the input order without performing the high-definition still image processing function.

That is, the high-definition still image data management module performs the high-definition still image processing function only with respect to the still image data including the high-pixel number information preset in the header information among the plurality of inputted still image data, The still video data, the general broadcast data, and the like are output without being subjected to the high-definition still image processing function in accordance with the input sequence.

Wherein the still image data transmitted from the external video data transmission system are all the same still picture data for the screen and the screen is divided into a plurality of areas and made up of a plurality of segment data for each of the divided areas, Information is allocated (see Figs. 2 to 5).

That is, each of the still picture data to be transmitted is divided into a plurality of areas (a) each of which is a1, a2, ..., an, and a plurality of segments ) Data, and is processed in advance so that each segment data is assigned unique sequential information.

At this time, sequential information of each segment data constituting one still picture data may be processed in advance so as to be included in the header information.

At this time, the high-definition still image data management module 220 performs the page mapping for each of the input still image data, and for each of the memory pages, address information corresponding to sequential information of each of the segment data The page mapping is performed so that the allocated memory block is formed.

The high-definition still image data management module stores each of the input still image data in a corresponding memory page of the mapped memory, wherein each of the segment data includes a memory allocated with address information corresponding to its own sequential information, And stores the still image data in the memory 230 so as to be stored in the block.

At this time, the high-definition still image data management module 220 superimposes the still picture data stored in each memory page of the memory when the dispatch end signal is input, and overlaps the segment data having the address information corresponding to each other Respectively.

That is, in the external video data transmission system, a plurality of still picture data processed by processing is processed so that the same picture is divided into the same plurality of areas, and the same segment data for each of the divided areas is transmitted, And storing the still image data in the corresponding memory page and, when the transmission end signal is inputted, superimposing the still image data stored in each memory page on the data so that the corresponding segments overlap each other, After the data is generated, the generated superposed data is output to the display side through the output terminal 240.

At this time, the data superimposition causes the data of a certain damaged segment of one memory page to be overlapped with the data of the undamaged segment of another memory page, thereby generating one undamaged superimposed still image data.

More specifically, the high-definition still image data management module determines whether or not data corruption of the still picture data stored in the memory is detected for each memory page and for each memory block, when the transmission end signal is input.

At this time, if it is determined that there is a memory page without data corruption of all the included memory blocks, any one of the memory page is outputted through the output terminal without performing the data superimposition.

If it is determined that all the memory pages include the memory block storing the damaged data, the still image data stored in each memory page of the memory is superimposed on the data to generate one output still image data and output through the output terminal The data of the memory block in which the damaged data of the memory block of one memory page is stored is replaced with one of the data of the memory block in which the uncommitted data of the memory block having the corresponding address information of the remaining memory page is stored, So that still image data of a memory page superimposed with the data is generated as the one output still image data.

Thus, if the still image data for three identical screens stored respectively in the three memory pages are not distorted in the transmission process for the same segment, they can be returned to the complete still image data before transmission and output , The still image data of the large capacity and high image quality processed by the external image data transmission system can be output to the display as it is.

In the above example, in the memory page of page number 1, the memory page of page number 2, and the memory page of page number 3, in which the input three still image data are respectively stored, If it is determined that the page exists, that is, if it is determined that data corruption does not occur in the transmission process, any one of the memory pages without data corruption is output through the output terminal. At this time, any one of the still image data may be selected as a memory page whose page number sequence number is the earliest among the memory pages without data corruption or an arbitrarily selected memory page.

In the memory page of the page number 1, the memory page of the page number 2, and the memory page of the page number 3 in which the three pieces of still image data inputted in the above example are respectively stored, At this time, the memory page of the page number 1 is damaged, the data of the memory block of the address information 1 is damaged, the memory page of the page number 2 is damaged, the data of the memory block of the address information 2 is damaged, In the memory page, if it is determined that the data of the memory block of the address information 2 and 3 is damaged, the data of the memory block of the memory page of the memory page of the memory page of the page number 3, 1 < / RTI > address information 2, The data of the memory block 3 is replaced by the data of the memory block which is the address information 3 of any one of the page number 1 or the page information 2.

At this time, any one selected memory page may be set to be either the memory page with the highest page number or the memory page with the least data damage rate or the randomly selected memory page.

The high-definition still image data management module may further include a memory page arbitrarily selected from among the memory pages, page information of the highest order among the memory pages, if it is determined that memory blocks storing damaged data are included in all memory pages And to select one of the memory pages having the lowest damage rate of the stored still image data among the memory pages as the memory page in which the one still image data for output is generated to perform the data superimposition.

At this time, the high-definition still image data management module 220 includes a transmission data determination module 221 that performs a function of determining whether page information or high pixel information included in the still image data input to the input terminal is included, A memory page mapping and transmission data storage module 222 for performing a memory page mapping function and storing transmitted and inputted still image data on a corresponding page, and a memory page mapping and transmission data storage module 222 for storing still image data stored in a memory page, May include a detailed configuration of the overlapping page overlap module 223.

In particular, when using the data processing apparatus for receiving an unmodulated high-definition still picture broadcasting according to the present invention, as shown in FIG. 1, the existing wired broadcast set-top box 100 ) And the display 300 and insert the still image data processing apparatus 200 according to the present invention so that the functions described above can be applied as they are.

That is, the apparatus for processing still image data according to the present invention is for receiving still image data broadcasting for realizing unmodulated high-definition picture broadcasting suitable for high-picture display, To perform a function of a set-top box for receiving high-quality picture broadcasts.

Hereinafter, a method of processing data for receiving unmodulated high-definition still picture broadcasting according to the present invention will be described.
