어디서든 Wi-Fi® 기기 간 HD 콘텐츠 공유

Wi-Fi CERTIFIED Miracast™는 Miracast® 기기 간의 매끄러운 멀티미디어 콘텐츠 디스플레이를 구현합니다. Miracast는 사용자가 Wi-Fi 네트워크가 없는 곳에서도 Wi-Fi 기기들 사이에서 무선으로 고해상도 사진, HD 비디오 콘텐츠 등의 멀티미디어를 공유할 수 있도록 해줍니다.


  • 모바일 기기에서 자동차 인포테인먼트(infotainment) 시스템으로 콘텐츠 전송
  • 노트북 스크린을 회의실 프로젝터와 실시간으로 공유
  • HD 및 4K Ultra HD 영화를 태블릿에서 HD TV로 스트리밍
  • 스마트폰, 컴퓨터, 태블릿에 있는 사진을 대형 스크린 텔레비전에서 감상
  • 다양한 A/V 포맷을 지원하여 모바일 기기 배터리 사용시간 연장

Miracast는 또한 블루레이 영화, 텔레비전 생방송과 스포츠 생중계, 기타 복사 방지된 프리미엄 콘텐츠 등을 언제 어디서나 감상할 수 있도록 지원합니다.

선 없는 생활을 앞당기는 표준 기반 Miracast

Miracast는 업계에서 널리 통용되는 솔루션으로서 다양한 기기 타입과 제조사 전반에서 기술이 실행될 수 있도록 해줍니다. 또한 Miracast 기기들이 적합한 설정을 자동으로 선택하기 때문에 손쉽게 연결을 셋업하고 사용할 수 있습니다. Miracast는 네트워크 인프라 또는 Wi-Fi Direct®를 사용하여 두 대의 기기를 서로 연결할 수 있습니다. 스마트폰 같은 Miracast 인증 기기에 저장된 콘텐츠를 자동차 인포테인먼트 디스플레이로 공유할 때, Wi-Fi 네트워크 연결이 없어도 됩니다.

Wi-Fi CERTIFIED Miracast 마크가 부착된 기기만이 Wi-Fi Alliance®로부터 다른 Wi-Fi CERTIFIED™ 기기와의 연동, 최신 보안 탑재, 고품질 사용자 경험 제공을 인증 받은 기기입니다.

Frequently Asked Questions
  • Are Wi-Fi CERTIFIED products protected by security?

    As of July 1, 2020, all new Wi-Fi CERTIFIED devices require WPA3. The only way to be sure that a product meets the latest security standards is to purchase only Wi-Fi CERTIFIED products.

  • How does Wi-Fi Alliance help ensure product compatibility and a good user experience for certified products?

    Compatibility and quality are achieved through testing of Wi-Fi products. Consumers should always look for the Wi-Fi CERTIFIED logo to ensure the best user experience possible.

  • What has changed in Miracast since its original release?

    New enhancements focus on high-definition (HD) content, increased performance, and better battery life for Miracast devices.

  • Is a Wi-Fi connection needed to stream a video from the internet?

    Miracast is unique to other wireless display solutions in that a direct peer-to-peer connection between two devices may be formed to share content residing on the source device, without the need for a Wi-Fi network. If streaming content from the internet, a network connection is required.

  • Does Miracast support devices like wireless speakers? (audio only)

    Audio-only devices are not part of the Miracast certification program.

  • How does Miracast protect premium content?

    Miracast provides industry-standard protection of premium content through support of High-bandwidth Digital Content Protection (HDCP). HDCP is a wireless adaptation of the same trusted content protection mechanisms widely used for cabled interfaces, providing diversity in premium content options. This feature is designed to protect the digital rights of content owners and to encourage their efforts to make their content available.

  • What formats does Miracast support?

    Miracast supports many commonly used audio/video format.  For a complete list, download the Miracast Technical Overview.

  • How is Miracast related to Wi-Fi Direct?

    Wi-Fi Direct allows devices to connect directly to each other, without the need for a Wi-Fi access point (AP). It simply requires the push of a button or the entry of a PIN. Wi-Fi Direct allows source and display devices to discover one another and provides the underlying device-to-device connectivity for Miracast. Miracast builds upon Wi-Fi Direct with mechanisms to negotiate video capabilities, setup content protection (if needed), stream content, and maintain the video session.

  • What features does Miracast certification test?

    Miracast certification includes testing for audio/video (A/V) latency, quality, and synchronization offset. Testing ensures that devices operate across vendors, provide simplified discovery and setup, meet the minimum display resolution requirement, and implement content protection (when implemented). Miracast devices are also tested for implementation of WPA2™ security. Wi-Fi Alliance members may view details on certification testing in the Wi-Fi CERTIFIED Miracast Test Plan.

  • Must both the content source and display be Miracast devices?

    Both the display and the source devices must be Miracast certified. Miracast may be used on devices without embedded Wi-Fi capability by using a Miracast-certified adapter that supports an interface such as High-Definition Multimedia Interface (HDMI) or Universal Serial Bus (USB).

  • What types of equipment are tested?

    Miracast certification is available for video-capable devices such as TVs, handsets, tablets, laptops, set-top boxes, cameras, and projectors.

  • What is the difference between Miracast and Wi-Fi Display?

    Miracast is the brand for the certification program operated by Wi-Fi Alliance. Devices that pass this certification testing can be referred to as “Wi-Fi CERTIFIED Miracast™ devices” or “Miracast® devices”. Miracast certification is based on the Wi-Fi Alliance Miracast Specification. This is the underlying specification developed by Wi-Fi Alliance members, and is copyrighted and owned by Wi-Fi Alliance. Wi-Fi Display is the original name for the Miracast technology.

  • How do I activate TDLS?

    Two Wi-Fi CERTIFIED TDLS devices will automatically form a direct connection after linking to the Wi-Fi network.  No user interaction is required.
