Get Rid of Wires and Enjoy Visual Entertainment
What can you do when friends and family want to look at photos or videos on their smartphones together? The answer is to use the wireless display function on your phone. This function lets you wirelessly project photos and videos directly to your TV without wires, allowing everyone to enjoy movies or stream content together.
Looking at Wireless Display Trends
Wireless display technology on the market today includes Apple AirPlay, Wifi Alliance Miracast, Google Cast, and others. Recently, these technologies have been adopted for smart home applications, stimulating the growth of this market. According to Verified Market Research, a survey research organization, the wireless display market has reached US$41.8 billion in 2021 and will reach US$112.4 billion by 2030. From 2022 to 2030, the compound annual growth rate is predicted to be 11.68%.
Why Do Wireless Display Fail So Often?
User experiences for wireless display technology vary from user to user. Some people have no issues at all, and some struggle to connect to any device. This is due to the differences in mobile devices, wireless display technologies, TV brands, TV systems, Wi-Fi chip modules, and more.
From experience, Allion’s audio-visual product consulting team has discovered that during mobile phone wireless display usage, the most common issue is image delay, which severely affects the viewing experience and causes users to file complaints.
Simulating User Scenarios and Analyzing Risks
Allion’s testing team used the most common user scenarios, the two most popular smartphone operating systems, and five different TVs made by different brands to conduct wireless display tests. Each test lasted around five minutes and below are the test results.
From the results in the table above, the issues could be caused by:
- Compatibility issues between TV Wi-Fi chips and smartphones
- Wireless connection issue
Next, these four categories were summarized based on the issues:
- Reduced picture quality
- Laggy video playback
- Reconnection could fail after disconnecting
- Automatically disconnecting during playback
It’s not enough to only understand the issues. After further clarification and analysis, Allion’s team has concluded that it could be caused by these reasons:
- Wireless network latency
- Wireless network throughput
- Wireless network packet error rate
- Wireless display app abnormalities
If wireless network throughput is too low, it can cause lags and delays during video streaming and a bad viewing experience, leading to customer complaints. Our consultants can make modification suggestions for your products based on your product development phase and the issues themselves, such as antenna interference design optimization, TV OS/App/Wi-Fi software and firmware updates, Wi-Fi chip module replacements, and more.
