High End Android based TV Platform Project

Development of a completely new TV platform from scratch using the Android OSP as the basis. Our role is to develop a “platform SDK” , introducing support for TV media playback formats and graphics optimization. Design and implement an Android based framework scalable across different HW platforms. Porting and optimization on specific HW platforms.
 

Architecture consultancy for creating new nice market Android product

Due to cost reduction and user experience issues, the customer decided to migrate its Linux/Java based  software stack to Android. We provided  consultancy services and helped to integrate their existing Linux based  system services to Android.

We managed to cover a large set of technologies required for integration:

• Graphics/Video integration
• Remote control integration.
• Graphics performance optimisation
• Integration of Linux native services with Android.
• Performance and boot-time optimisations.
• Integration low level Linux services with Android Power Manager.

Technologies Used: DM8168 Netra, Linux Kernel, Android Framework

Graphics performance optimisation of a tablet of an Asian OEM

Several weeks before production start of the customer's new tabet, there was a major problem with the device performance. We provided on-site support, resolved the major technical problems and significantly increased the system performance. Optimisations where done in the GPU drivers, in power management modules and in the OS. The product was launched in the scheduled time.

Platform: CE4100 
Technologies areas: Project Management, Lead Programming, Architecture, Qt, Android

Development of a Qt based SmartTV platform integrating a SurfaceFlinger graphics composition system for a European TV OEM

We headed the development of a Qt based SmartTV platform. To support the legacy graphics libraries and integrate it with the new UI, we developed a SurfaceFlinger based graphics composer. This allowed the simultaneous composition of surfaces/windows from different graphics frameworks like Qt, Android, DirectFB and display it on the same screen. Using this innovative idea, the customer was able to leverage from the high level of maturity of SurfaceFlinger and from the availability of  Android baseports on popular chipsets.

Graphics & Multimedia framework development & optimisations on low cost mobile platform

Development of graphics and multimedia services for an Application Framework, highly optimized for performance and small RAM/ROM footprint

•  Designed and implemented a 2D software rendering engine for
    high performance applications and games, with hardware
    acceleration if present.
•  Designed and implemented a display driver API (DI3) with support for
    multiple pixel formats (RGB, YUV), displays and 2D hardware acceleration.
    This included full emulation of all features on PC.
•  Optimized JPEG decoder for ARM7, achieving <2 seconds  decode
    &amp; rescaling time for 10 MPix baseline JPEG on 57MHz cpu.
•  Alpha blending UI layers through SW routines, optimized for ARM7.
