Evaluation Foreword

It is undoubtedly the most beautiful combination for audiophiles to watch AV multi-channel home theaters and listen to high-definition music on the same source. In the era when CD and BD discs were used as storage devices, the industry once positioned the relationship between oil and water for both, although both were top enjoyment of sensory experience, However, it seems that they ended up going their separate ways - the processing of video and audio sources must go their own way. With the iteration of information technology, when storage devices span to file based disk arrays, when online video services become possible, and when the Android based open operating system begins to become popular, information sources become the core of home entertainment, which not only opens the door to watching AV multi-channel home theaters and listening to high-definition music, but also allows networking to enjoy information services and deepen human-computer interaction.

3、 Local broadcast control management

Cabol Q20 has positioned itself as the flagship computer king and is a 4K Blu ray hard disk player with high fever. Therefore, it has made great achievements in film and television broadcast control and decoding. After ten years of hard work, the sword has finally come out.

① Movie library function

Each player has its own movie management system. Traditional players usually use file list to manage movies and interact with users through the screen, as shown in the figure below. A long list of English movie names is not convenient for users to understand the movie. We don't know what the Chinese name of the movie is, nor what the main content of the movie is.

To match the previous movie file list

The innovative introduction of the video library management function of Cabol Q20 enables online automatic matching of local movies with movie posters, profiles (including actors, directors, producers, and movie introductions), douban ratings, and movie classifications. After successful matching, it supports the initial search and classification screening of local movies.

② Blu ray navigation

The disadvantage of commercially available Blu ray hard disk players is that they cannot realize Blu ray navigation. Some Blu ray films packaged in multiple versions cannot be selected, and there are also some sidelights that cannot be watched. This is the reason why many fans are not fond of Blu ray hard disk players, and it is also an insurmountable "gap" in the industry. The biggest advantage of Cabol Q20 is that it supports navigation of Blu ray original disk (BDMV) and Blu ray ISO, and can select subtitles, audio tracks, and chapters. The current firmware version tested by the author only supports simple navigation of Blu ray, but according to the official news, the future will achieve perfect navigation through firmware upgrade.

③ Online subtitles and subtitle management

In the scene of the test "Beautiful Heaven" video, the texture of the tea set on the desktop is clearly visible, and the leaves behind still have no "mosaic" feeling when viewed on the 65 inch TV screen. It can be seen that the Cabol Q20 achieves 4K point-to-point output, accurately restores every detail, and plays smoothly without stuttering.

The color saturation of the picture will be higher and the color transition will be smoother; The BT.2020 color gamut and 10Bit color depth are both attributes under the ultra-high definition blue light standard, and they represent the quality and quantity of colors respectively. The BT.709 color space is used in the ordinary blue light standard, which only covers 35.9% of the BT.2020 color space. The latter is the largest color space in the current display equipment, covering 75.8% of the CIE 1931 color space. The number of 10Bit deep colors reaches 1.07 billion colors (8Bit The color depth is only 16.77 million colors). Cabol Q20 supports 10Bit color depth and BT.2020 color gamut space display. In the face of 10Bit color depth decoding test, most players on the market will be more or less under pressure. However, Cabol Q20 decodes SES Astra demonstration film perfectly. The overall color performance is gorgeous, warm color system performance, smooth color transition, and no band problem in color performance, The image quality presented under 10Bit color depth is good.
