Broadcom Enables Mobile Device Content to Escape the Tiny Screen with Wi-Fi Display

Enabling the Phone to TV Revolution

With the increased availability of faster mobile networks, end users are using more bandwidth-intensive applications and consuming significantly more high definition video on their mobile devices. Wi-Fi Display couples Wi-Fi and H.264 video encoding technology to allow the consumer to seamlessly move the mobile user interface from a small screen to a bigger display while maintaining control via the touch screen. Since consumers demand real-time interaction with games, movies and apps, only the best implementations of Wi-Fi that are tightly integrated with high quality video codecs will result in a solid user experience.



Broadcom's best-in-class Wi-Fi solutions for mobile and STB/TV have been engineered to minimize packet loss and mitigate interference while maximizing screen resolution and picture quality. In addition, as 5GHz Wi-Fi based on the 802.11ac standard enables wireless network bandwidth over 1 Gigabit per second, Wi-Fi Display will be able to seamlessly stream ultra-high definition content such as new 2K and 4K resolution digital media between devices.



Standards and Third Party Support

The Wi-Fi Display specification driven by the Wi-Fi Alliance is based on mature H.264 and 802.11 standards. Broadcom is fully supporting and contributing to the Wi-Fi Alliance process to achieve full interoperability among suppliers of source devices that send an encoded video signal and sink devices that can receive the encoded video signal. Broadcom is working with multiple third party partners as well as tightly integrating the technology into its own STB and mobile SoCs to ensure the highest quality end-to-end user experience.
