Texas Instruments Inc. has introduced a solution that supports the Miracast wireless video standard for the display of full HD content from a mobile device onto a larger screen over a secure, low-latency, wireless network connection.

The WiFi Alliance's Miracast certification program provides a standards-based solution for streaming video and audio content over a peer-to-peer WiFi Direct wireless network to ensure interoperability between devices such as mobile phones, tablets, HDTVs, projectors and audio receivers.

TI's OMAP processors and WiLink connectivity solutions leverage the low-power multimedia processing and M-Shield content security capabilities of the leading OMAP platform jointly with the WiLink connectivity product line. According to TI, these devices provide an optimized solution that is designed for Miracast certification, which will be available later this year.

Expanding the wired HDMI external display and WiFi Direct capabilities in Android, TI delivers a rich experience for the Android platform that will enable mobile device manufacturers to rapidly integrate wireless casting into products, the company noted. Whether mirroring the Android device's display or streaming full HD content, the combined architecture of the OMAP applications processor and the WiLink connectivity solution offer a low-power optimized system without sacrificing media quality.

TI's hardware and software resources enable Android device manufacturers to leverage Miracast capabilities for various applications.

  • Multitasking while streaming: With video processing offloaded to a dedicated OMAP hardware accelerator, consumers can use a mobile device to simultaneously stream music or full HD movies to a 1,080p capable TV, while continuing to multitask with Web browsing or other mobile apps, checking the latest scores, managing email, texting and more. The WiLink solution delivers a WiFi-enabled display connection to the TV concurrently with an Internet connection through a WiFi access point.
  • End-to-end streaming: A user can start a YouTube application on a mobile device and mirror the application user interface to the TV. Then the user can choose a video from the YouTube video gallery and send the content in full screen mode to a big screen TV, while continuing to browse the YouTube app for other videos. This same concept applies to other free and paid online premium video services as well as online TV services, and is made possible by the WiLink connectivity solution's ability to concurrently connect to the cloud and to the Miracast-certified display.
  • Protected premium content: TI's planned Android solution for Miracast builds on the capabilities of the M-Shield secure execution environment and can process video in conjunction with any DRM scheme. This ensures that premium protected content is securely played back on the mobile device and HDCP encrypted during wireless streaming to a remote Miracast-certified display.
  • Wider content choice for the playback experience: The TI solution designed for Miracast can support a wide range of video content formats from the cloud and transcode it as required thanks to its multistandard hardware encode/decode accelerator to match the decoding capability of the Miracast-certified display.
  • UI mirroring for big screen gaming: In this mode, a user can send the exact content of a small mobile device display to a much larger screen. This brings the interactive experience with a mobile device to a new level. Users can play the latest video games as well as share photo galleries, applications and other mobile content with family and friends in comfort on a big screen rather than gathering around a mobile device. The TI solution designed for Miracast, based on the OMAP processor and WiLink connectivity family, can deliver a smooth and satisfying user experience for this popular use case, the company said.

TI expects its solution to be WiFi certified Miracast when certification is available later this year, while working with customers to rapidly introduce Miracast-certified products to the market.

This solution is available now to high-volume OEMs and ODMs. TI plans to have a solution for Miracast using the OMAP 5 processor and WiLink 8.0 solution later this year.
