The primary purpose of MIPI Display Service Extensions (MIPI DSE℠) is to define flows and mechanisms to enable various end-to-end display services to be carried over MIPI A-PHY℠ links between automotive display sources, such as host processors, and display peripherals, such as active-matrix display modules. By enabling these services, which include High-Bandwidth Content Protection (HDCP) and various functional safety features, MIPI DSE helps to standardize and streamline the integration of high-performance display systems in next-generation vehicles.
To do this, DSE defines a common video format, Service Extension Packet (SEP), to provide packetization and uniform delivery of display content over MIPI A-PHY with the tunneling of all native-specific abilities of both MIPI Display Serial Interface 2 (DSI-2℠) and VESA Embedded DisplayPort/DisplayPortTM. This allows for display systems with heterogeneous display formats. The display stream content can be converted to and from the SEP format into A-PHY A-Packets at bridges or by the display source and sinks at their protocol layers, for end-to-end abilities.
MIPI DSE is a component of MIPI Automotive SerDes Solutions (MASS), a standardized, end-to-end connectivity framework based on MIPI A-PHY for the integration of automotive image sensors and displays with built-in functional safety and security.
The DSE specification was developed by the MIPI Display Working Group and is available only to MIPI Alliance members. For information about becoming a member, visit Join MIPI.
