Intelligent optimization and compression technology of delta file.
Update all types of electronic contol units of vehicular system, including multi-module softwares.
Whole-life-cycle management system specially developed for bill of material, task management and report.
Using safe cloud and client-side, safe network ensures vehicular integrity.
Modulized platform framework of solution is expandable.
Capture big data and encapsulate the data as practical content.
Global project tracking is performed via cloud and network interfaces.
Upgrade content intelligently depends on analysis and upgrade support is provided. Either all is successful or all is rolled back.
1¡¢Artificial intelligence differential technology
By adopting optimized smart differential package technology based on artificial intelligence and profound study, Auto OTA of Redstone is able to achieve the followings:
Sizes of automotive software packages vaying from KB to GB.
Reduction of data transferred and pocessed can evidently reduce costs and resources required by update.

Corresponding applications include electronic control unit software or binary file update of other original hardware, on-board navigation map data, music, pictures, videos and user customized content, update of operating system, applications and software package etc.
2¡¢Realization of ADAS(Advanced Driver Assistant System) upgrade of mass production vehicle
Superiority of OTA of Redstone in ADAS(Advanced Driving Assistance System) upgrade£º
Update package with multi-layer encrypted signature and decryption signature verification in vehicle.
ADAS Fota Project of Redstone has passed trans-scenary pressure test with high intensity.
The project supports parallel docking with other manufacturers¡¯ADAS upgrade except Baidu.
FotaClient SDK of Redstone supports trans-OS and trans-chipset platforms
E.g: BAIDU has tried OTA of Redstone for ADAS upgrade
