Is wireless home theater a reality? There are many technical problems
In the Internet era, everything is wireless, but home theater systems seem to be an exception. Most of the 9.1 audio systems still use wired design, and new audio systems such as Dolby Atmos can't get rid of cables. There is no doubt that cluttered cables are extremely affecting the user experience. When will the home theater completely get rid of the wires?
Wireless home theater system status
First of all, wireless is mainly concentrated in the audio part of home theater. After all, Blu-ray DVDs and streaming media set-top boxes are not necessary for wireless, but audio systems are different. The amplifiers, the complex connection of multiple speakers, and a bunch of cables are probably every User nightmare.
Currently, vendors such as Sonos have introduced a 5.1-channel audio system that can be used as a good home theater sound system. Although Sonos entered the wireless multi-room audio market very early, its reputation is not bad, but it is clear that traditional audio manufacturers do not appear to have entered the market on a large scale.
The Optoma WHD200 Wireless HDMI System is a fully-positioned wireless relay system, but there are obvious limitations. First of all, HDMI-based wireless forwarding systems are within 10 meters of each other, and there are also latency issues. Processing 4K video is obviously more difficult, and even if it supports multi-channel audio, the overall effect is not entirely satisfactory.
As for Google Chromecast and other products, more are still targeted at wireless playback gadgets, plug and play method is very convenient, but limited scalability, does not really belong to the category of home theater systems.
Technical challenges for wireless home theater
Obviously, audiophiles still tend to choose cable AV systems. One of the important reasons is that cable signal conversion rate is more stable and more efficient, and well-designed shielded cables help the entire system to achieve better playback results. Obviously, wirelessization and simplification are the future development trends, but it will take some time to overcome technical obstacles.
First of all, the wireless signal transmission performance based on WIFI still needs to be improved. Although some high-end 802.11ac routers have enhanced the signal output, they still cannot achieve stable transmission effects in some environments where new home improvement materials are used. Secondly, the wireless home theater system also needs to take into account the connection and performance while applying the current popular smart technology, to achieve simpler control and adjustment functions through the mobile phone application, and to change the previous complex operating methods, it is possible to further obtain ordinary The user's pro-gaze.
