The rest of the interfaces are on the back of the machine, from left to right are WiFi antenna, fiber audio, AV output, HDMI 2.0, wired network interface, reset button, and power input. It is worth mentioning that the Haimeidi H7 fourth generation and the third generation of the same product, equipped with HDMI 2.0 interface, transmission rate up to 18Gbps, for some large-stream video, you can easily achieve transmission.

Haimeidi H7 four-generation 64-bit 8-core Amlogic S912 processor, the chip has attracted widespread attention as early as a year ago, based on ARM Cortex? The A53 architecture, with a maximum frequency of 1.5GHz, can achieve lower power consumption and high energy efficiency at high performance. The GPU is an ARM Mali-T820MP3 GPU, 750MHz, supports 4K@60fps 10Bit HEVC, and HDR supports Dolby Vision. , HDR10, the output is compatible with HDMI2.0a and CVBS. As a new generation of processors, Amlogic S912 is positioned in the field of high-end 4K OTT boxes and game boxes, destined to bring extraordinary video entertainment experience. Combined with 2GB of large memory and 16GB flash memory, the new hardware configuration can be said to be full of sincerity. The following is the situation of Ann Bunny's running on the Haimeidi H7. The 41447 points are sufficient for a smart box to satisfy the needs of all members of the family for film and entertainment.
In addition, the Haimeidi H7 fourth generation is more optimized than the third generation WiFi, supports dual-band WiFi, can support 2.4GHz/5GHz 802.11a/b/g/n/ac connection. At present, the wireless routing, USB wireless mouse and keyboard set, Bluetooth, etc. in the home use more 2.4GHz frequency band, so if WiFi continues to use 2.4GHz will receive more interference, stability will certainly be discounted, due to the use of 5GHz channels in the family There are fewer wireless devices, so the WiFi connection using this band has less interference; in addition, the 5GHz theoretical bandwidth is 867Mpbs, 2.4GHz is only 300Mpbs, so compared with 2.4GHz single-band WiFi, 2.4GHz/5GHz dual-band optional The Haimei Di H7 generation of WiFi will get a more stable and smooth wireless network experience.
Bluetooth 4.2 is also a member of the H7 four-generation upgrade. The higher version of the Bluetooth protocol brings more stable wireless transmission. It is worth mentioning that the fourth generation of Haimeidi H7 can connect speakers, mice and keyboards, and handles via Bluetooth. Equipment, try to think about it. Isn't it easy to enjoy one's Hollywood blockbusters via Bluetooth wireless headsets, or to think about the joy of gaming through Bluetooth?
In addition, the largest upgrade of the Seamax H7 fourth-generation software is equipped with a new generation of Android 6.0. The system is optimized for fluency, allowing the application to run in the background and no longer consuming memory, and is linked with 2GB of large memory. Whether it is system control or application operation, the speed is very smooth, users do not need to wait for control, and can freely install software to meet the needs of the family; and in the system UI, the fourth generation of Haimeidi H7 continues the sea Meidi family HIUI, I believe that we are very familiar with and like HIUI's ease of use and simple logic level design. We will not explain it here. This is a system that is very suitable for human-computer interaction on smart TVs. Both adults and children are Can easily grasp.
Voice control In addition to the ultra-quiely control experience brought by Android 6.0, the Haimeidi H7 four-generation also joined the Bluetooth voice control, will be manually manipulated into a voice control, simplified, support for Mandarin, Cantonese, Sichuan dialect three Language control, can search, change Taiwan (the need to install HDP TV live APP), simple system control, application open, query and chat.
Thanks to Haimeidi's hardware and software optimization on the Bluetooth voice remote control, Haimeidi H7 fourth-generation voice control has a high degree of recognition and response, but for the online broadcast control instructions, the Haimeidi H7 four generations have yet to be optimized. It is worth mentioning that the four generations of Haimeidi H7 can recognize not only speech but semantics. For example, when searching for films, we can directly say the film title, or we can say “I want to see xxx”. Can do on demand. The following are some of the voice tests that the author did on the Haimeidi H7 four-generation voice control:
The meaning of the voice control function lies in simplifying operations. For example, parents want to change TV stations at home, but do not understand the complicated operation of the box. Now they can just press and hold the remote control voice key to perform voice switching, such as remote control. Say "I want to see CCTV5", the box will automatically switch to the central five, very convenient; In addition, usually when we search for videos, we search by inputting the first letter, and after the voice control, we only need to face the remote control. The name of the film can be shouted, greatly improving the user experience and bringing more enjoyable living room entertainment.
Online Content Haimeidi H7 is quite powerful in terms of content resources. It has a genuine license for CIBN Internet TV, 2 million hours of free video resources integrated with Tencent videos, hits, homemade dramas, cinematic screenings, Hollywood blockbusters, and hits. Variety, sports events and other networks are updated synchronously. Compared with other broadcast control platforms, Haimeidi H7 has the exclusive NBA and Champions League video resources of Tencent.

The following is the video content ranking of Baidu's hot search. In the fourth generation of Haimeidi H7, almost all movies and TV series are included. Most of the variety shows are also included. Tencent's video resources are still very rich in resources.
For popular matches such as the Champions League and other events, Tencent Video has the right to broadcast/record all the schedules and events. Just enter the “sports” channel to learn about all the schedules. You can watch the live broadcasts at the point of time, and you can watch on-demand on time. Never miss for every game.
In addition, the resources of the NBA are also one of Tencent's important selling points. Let's take a look at the exciting VS Lakers NBA regular-season tournament that ended on October 27th. The clarity is also the leverage of the 1080P!
For a box with genuine broadcast control, video VIP membership fees are a must. Compared with the large number of VIP members on the market, Tencent Video's annual fee of 300 yuan (which is less than a dollar a day) is still relatively humane. of.

HDR video is smoothly decoded and played. The dynamic range of the dark and bright parts of the video is larger, and the flame details are more outstanding in the dark. The HDR output function can be selected to open, auto, or off in the playback settings.
