DLNA Technology Is Not Outdated: Its Unique Value in the Multi-Screen Interaction Ecosystem

When wireless screen mirroring has almost become synonymous with “screen mirroring,” we can’t help but ask: Is DLNA, this established protocol, already outdated? The answer is no—it still has unique advantages in smart home scenarios.

1. Core Advantages of DLNA: Focus and Efficiency

  • Focus on Media Playback: DLNA was originally designed for sharing and playing local media files (videos, images, music). It excels at this task with exceptional efficiency.
  • Liberate the Transmitting Device: After using DLNA to cast a video, you can turn off your phone screen or use the phone for other tasks without interrupting TV playback. This is highly power-saving for the device.
  • Simple and Intuitive Operation: You can directly tap the cast icon in video/music apps to start casting, no need to switch to system settings. This ensures a smooth user experience.

2. Typical Application Scenarios of DLNA

  • Home Audio-Visual Center: For audio-visual enthusiasts, it’s a common practice to cast high-definition movies downloaded on mobile phones or NAS (Network Attached Storage) to TVs via DLNA for playback.
  • Background Music System: Cast music playlists from your phone to DLNA-supported wireless speakers, creating a whole-house background music system that enhances daily life ambiance.
  • Digital Photo Album for Memories: During family gatherings, use DLNA to play group photos and travel pictures from your phone on the TV in slideshow mode. This creates a warm atmosphere for sharing memories.

3. Complementary Relationship Between DLNA and Multi-Screen Interaction

DLNA and screen mirroring are not mutually exclusive—they complement each other, jointly forming a complete wireless screen mirroring ecosystem.
  • Need to cast local movies/music? Use DLNA for a better experience.
  • Need to present PPTs, operate apps, or conduct group discussions? Use multi-screen interaction (screen mirroring).
In today’s fast-evolving wireless screen mirroring technology, understanding and making good use of DLNA, this classic protocol, can make your digital life more convenient and seamless.
