Wi-Fi applications on in-vehicle video performance
Although video over Wi-Fi applications have been available for quite some time, this is the industry’s first attempt to develop an interoperability specification for video distribution. It specifies provisioning and management for negotiating video capabilities between a source and sync device, standard video transcoding schemes built on H.264, transport and control schemes, packetization, and content protection based on High-bandwidth Digital Content Protection (HDCP) 2.0. Many of the device and in-vehicle discovery components of the protocol are built around the previously released Wi-Fi Direct specification. The WI-FI CERTIFIED Miracast specification enables car manufacturers to wirelessly mirror smartphone screens to in-dash LCDs, creating an immediately personalized interface in the dashboard. Additionally, this in-vehicle standards-based technology allows consumers to safely control smartphones through the dashboard so they can answer calls and check text messages.
