Understand what you think new experience Changhong artificial intelligence TV Q5K evaluation

If you want to say that the most popular technology in the television camp is now, it is not "artificial intelligence"! In recent years, many domestic and foreign color TV manufacturers have been vigorously promoting artificial intelligence TVs. In the past year alone, many new products have been launched. Among these, the most representative one is Changhong's new product: the artificial intelligence TV CHiQ Q5K series. . As the first home appliance manufacturer to implant artificial intelligence concepts into TVs, the Q5K series is already the third generation of artificial intelligence TVs launched by Changhong. Upon listing, it leases high-value, built-in far-field voice, super-fuzzy search, and sound. The characteristics of pattern recognition and voice-activated operation are highly valued by the industry, media and even users. When it comes to intelligence, many TVs were limited to the installation of applications and the operation of mobile phones. Although they all support voice input, the user experience is very poor. The voice recognition rate is low, only a fixed syntax can be input, and it can be applied. There are few scenes, the remote control must be operated at close range, and so on, which can only be regarded as the embryonic form of artificial intelligence televisions and belong to the era of AI 1.0. The "semantic analysis" that can be done is an advanced AI 2.0 era artificial intelligence TV, which can realize the functions of analysis and recommendation by understanding user semantics. Changhong's latest CHiQ Q5K series of artificial intelligence TVs with far-field voice and voiceprint recognition technology not only can answer and understand what users need through “artificial intelligence + big data + deep learning”, but also lose mobile phones and remote controls directly. Natural interaction with users and artificial human-television televisions have become more humane and have entered the era of AI 3.0.
So is it really so smart? At present this TV has come to our evaluation room, the following author will take everyone to verify it. The first thing you send is its main parameter configuration.
7.9mm ultra-thin all-metal Changhong artificial intelligence TV Q5K Appearance Changhong CHiQ new Q5K has a high value, all-metal body, thin at only 7.9mm, and the choice of aviation aluminum alloy material, light and sturdy.
Changhong artificial intelligence TV Q5K voice test Changhong artificial intelligence TV Q5K the biggest selling point is the artificial intelligence voice part, after experiencing the iterative upgrade of the third generation of products, Q5K further improved the human-computer interaction technology and machine deep learning ability to create more Service scenario. At the same time, far-field voice, voiceprint recognition, super-fuzzy search, and the addition of voice-activated operations also make the interactive experience more simple and natural.
Far-field voice recognition beyond 5 meters does not need much to accurately recognize human voice, but traditional voice interaction needs to be performed manually. For example, pressing and holding a remote control to send voice commands has limitations in terms of convenience and speed. At this time, the advantage of far-field speech recognition that truly enables “free hands” is reflected. Through the television's built-in microphone array, you can control the TV in a range of pure voice by activating a far-field voice recognition function by speaking a specific “wake-up word” without touching any device.
The first feature to test first is far-field speech. Changhong Q5K used the same sound size to test the Changhong Q5K at the positions of 1m, 2m, 3m, 4m, and 5m in the test process. The test sentence was: "Changhong Xiaobai, boot", TV The machine will open. Found that within 5 meters, Q5K's voice recognition are very accurate, when the author tries a longer distance, just slightly increase the volume, can be accurately identified, which is difficult to achieve on other television.
With voiceprint recognition technology, TVs provide personalized visual and content services based on recognized characters (eg, men, women, children). Changhong Q5K supports multi-person voiceprint registration and role classification. It distinguishes the users who currently use the TV by the different voices of each person, and learns and analyzes the user's habit of using TV to achieve accurate content recommendation.
The actual effect is that boys and girls respectively say “I want to watch movies” to Changhong Q5K, and Q5K will present different visual effects and recommended videos based on identification. The interface for women is soft pink, and the recommended film is mainly romance, while men will see dark blue vision, as well as some movements, science fiction-based video results. If you are a kid, you will get some cartoon recommendations.
Currently, mainstream smart TVs on the market have basically the function of voice recognition. The difficulty in voice interaction lies in semantic understanding. Can not understand the user's intention is a major test of artificial intelligence technology. Therefore, we have specifically selected several types of test items, each of which uses a variety of instructions to see if the TV can perform accurately.
At the most basic functional testing stage, we tested some of the functions most frequently used by users, including finding films, checking the weather, checking names, and so on, which can be accurately implemented. During the playback process, the Changhong Q5K TV can also be controlled by voice commands for mute, set, return, and volume increase/decrease. Advanced points such as "too bright" and "too dark", Changhong Q5K can recognize the user's intention "adjust brightness". During the filming process, she said "I want to watch her husband's movie" and "I want to watch her husband's TV show" on TV. Changhong Q5K can accurately find Deng Chao's film and Chen Xiao's TV series.
With voice as the carrier's interactive method, it is inevitable that there will be a problem of misinterpretation when speaking, and sometimes the user may send a missed tone promptly, sometimes it is easy to say wrong. Whether the TV has the self-correction capability and the user finds the correct audio and video content under the circumstances that the user's objective instruction is wrong or the machine itself has recognized the error is a competitive point that the test wants to test.
We deliberately described "Brother who slept in your upper berth" as "Sleeping in Your Bottom Brothers" and did not expect to really play the desired content. It can be said that whether Changhong Q5K is a typo, a homonym, or a reduced character, it can be automatically corrected to find the correct content of the user's target.
Summary: Changhong artificial intelligence TV Q5K can be said to be the most natural, accurate, and efficient artificial intelligence in the current TV industry, voice input is no longer a gimmick, can let you really put aside the remote control.
How to measure the quality? Measured to give you the answer As a high-end 4K TV, the quality is bound to be the most essential element, Changhong 55Q5K's actual performance is also our concern. After a professional instrument BM-7 (brightness meter) test, the specific image quality parameters of Changhong Q5K TV are: when the LED backlight is adjusted to the maximum, the measured brightness reaches 408.3 nits and the contrast ratio reaches 1236:1, in which the brightness is significantly higher than At present, the average level of 300 nits on the market is relatively good.
The measured NTSC color space 78.23%, while basically covering the 100% SRGB color gamut, slightly higher than ordinary television about 74% of the NTSC color gamut, the performance is quite good.

In terms of definition, we specifically broadcasted the test piece source. In actual tests, this TV also reached a higher level, and the dynamic picture has no obvious trailing phenomenon.
As a 4K Ultra HD TV, the performance of the details of the screen is also worthy of attention. After releasing a group of real shot ultra-high-definition pictures and videos, the screen shot is inevitably slightly distorted, but it is still possible to see the accuracy and transition of the color expression through comparison of different pictures. For example, the skin color of the characters in the image below, as well as the red and green display, are all excellent levels in the same TV.
During the testing process, we used the method of playing local files. During the playback of full HD or 4K ultra-clear resources, there was no caton jump frame. The playback was smooth, and the operation response of fast forward and fast rewind was also very sensitive. The decoding capability is fully reflected. Especially when playing 4K HDR format movies, it can be clearly seen that the highlights and shadows have been optimized, and the details of light and dark details are very obvious, which is better than the current large number of logarithmic equivalent products.
Nowadays, for a TV, the importance of sound quality is no worse than the picture quality. Consumers are eager to get the shocking effect of the movie version without leaving home. Changhong artificial intelligence TV Q5K uses a front waterfall audio set, with 1500ml large sound cavity, combined with the latest Dolby MS12 surround experience technology, so that stereo surround sound everywhere, compared to traditional LCD TV speakers performance performance is even more outstanding.
In the test section, we chose a dedicated audio test disc and high-definition movie "Iron Man 3" for playback.
In terms of performance, the sound source of the sound is purer and the bass is more shocking, further enhancing the sense of presence when watching TV. From the playback effect, it is undoubtedly the deepest impression of the low frequency, which brings a strong sense of bass and bass texture, which we can from the ** launch to the explosion, Iron Man armor of the impact of a clear perception.
