Google Cast Technology Analysis: Redefining the Screen Mirroring Experience
In the field of smart screen mirroring, Google Cast—an innovative technical solution launched by Google—is reshaping the way devices connect. More than just a mirroring tool, this technology forms a complete ecosystem, delivering a brand-new multi-screen interactive experience for users.
Google Cast Technical Architecture
Google Cast adopts a unique “command transmission” architecture, distinguishing itself significantly from other mirroring technologies. Its core working principles include:
- Device Discovery Mechanism: Automatically identifies Cast-enabled devices in the network based on the mDNS protocol.
- Command Control Mode: The sender transmits only playback commands, while the receiver fetches data directly from the content source.
- Content Transmission Path: Media streams bypass the sender, reducing losses from intermediate links.
- Multi-Protocol Support: Compatible with mainstream streaming protocols such as HTTP Live Streaming and MPEG-DASH.
Technical Advantages Analysis
- Low Power Consumption Design: Significantly reduces power consumption of the sender device.
- Multi-Task Support: Enables use of other apps while mirroring is in progress.
- High-Quality Visual Guarantee: Supports 4K HDR video transmission.
- Cross-Platform Compatibility: Fully compatible with Android, iOS, and Windows systems.
Google Cast’s technological innovations have brought fresh perspectives to the screen mirroring industry, and its unique architectural design is worthy of in-depth learning and reference across the sector.
