Hereinafter, an entry-level mainboard for ultra-high-definition television supporting an OLED panel according to an exemplary embodiment of the present invention will be described in detail with reference to the drawings.

First, in connection with the present invention, UHD TV broadcasting equipment requires the following technologies.

1. UHD content real-time input / output technology

-Consideration of employment standards (SMPTE292M, SMPTE372M, etc.)

-Bandwidth consideration: 3.xGbps vs. 7.xGbps vs. 30Gbps

-Consider commercial interface implementation for testing (HD / 3G-SDI, HDMI, etc.)

-Review and selection of bus specifications for storage / playback

2. Lossless UHD video compression technology and visual lossless compression technology for editing (video compression technology)

-Lossless image compression technology is developed based on ISO / IEC 14495-1 / 2 JPEG-LS or FFV1 algorithm with high compression ratio while keeping the complexity to a minimum while improving the compression ratio.

-In particular, the compression rate will be increased by using inter-plane correlation between R / G / B. However, due to the low compression ratio of 1/2 to 1/3 due to the characteristics of lossless compression, it is expected to have difficulties in real-time storage for UHD content, especially 8K video, so alternatively, a visual lossless video compression technology for editing is also developed.

3. Lossless multi-channel audio compression technology (audio compression technology)

-Low-complexity, high-efficiency lossless audio codec technology with maximum supported channels of 1023 ch, supportable sample analysis degree 8, 16, 24, 32 bits, IEEE 32-bit floating point, maximum sampling frequency 192 kHz, and other lossless audio compression codecs Improved low-complexity performance based on MPEG-4 ALS that can provide higher scalability and higher quality audio

-The development of a low-complexity lossless audio codec can solve the problem of the data size of the PCM data, and the impact on the entire system is insufficient due to the low complexity.

-Since not all channels always have the same effect in the overall audio service, some channels are significantly important in the overall audio signal, while some channels are less important. Therefore, by applying the lossless compression method to the high-priority channel and the existing lossy compression method to the low-priority channel, it is possible to provide a significantly higher quality audio service than the conventional lossy audio compression method.

4. UHD video storage format technology (file format technology)

-Analyze and expand MXF file format

-Implementing the developed MXF-based extension file format module for UHD, and optimizing and testing the performance of the implemented module

-Interworking with editing software through library of integrated file format including UHD video and multi-channel audio

5. HD-to / from-UHD video conversion technology (image enlargement / reduction technology)

-Ultra-high resolution image reconstruction technology: sub-wavelength approach, non-uniform interpolation approach, optimization approach, sample-based approach

-Regularized repetitive image interpolation: Restoring high-resolution image sequences by restoring from low-resolution images, and a large amount of information in the improvement phase rapidly decreases when the interpolated image sequence approaches the high-resolution original image sequence, and can apply the stapler to the encoding method

6. Color correction technology between images (image matching / correction technology)

-Statistical color distortion model generation

-Independently generate color and structural distortion models and unify them through testing

-Iterative algorithm generation for minimum error implementation

-Development of image matching technology for estimation of mutual information in real images

-Development of optimization technology to improve performance from a small amount of mutual information
