Video
The video application, as well as Real Player are not so much interesting to the user in terms of video clips playback on the big wide-screen display with 3.2” diagonal. Besides, the 10.0.004 firmware, which we used during tests lacks many codecs, thus we left our hopes to enjoy numerous clips and films with 640x360 resolution.
But we are more interesting not in the video playback, as it is, but in the reasons, that make Rapidoyawe 1.13 used in the 5800 XM provide better picture with 30 frames per second refresh rate, while the same processor installed in the N85 fails to cope with this task.
It is funny, but the reason may is that the 369 mHz CPU ARM 11 utilized in the 5800 is not the main video decompressor, as OMAP deals with it. Yes, it is exactly OMAP, unlike that one used in the N82. It has DM500 coprocessor providing a high-quality compression of the video stream, when recording, as well as its quick displaying. It is that component, which some articles call 3D Image Engine, though it is more correctly to call it an accelerator.
Some crazy Russians from eng.mobiset.ru found that the 5800XM has a Video Acceleration Co-Processor? Interesting... No wonder my converted vids are a bit TOO smooth IMHO for the 300++ Proc alone...

Shame it can only do DIVX/XVID/MPEG4...

OMAP-DM500 and OMAP-DM299 coprocessors
The highly integrated and OMAP-DM299 multimedia coprocessors combines low-power hardware and programmable image processing capability to provide high still image and video quality for low-cost camera phones. Using the coprocessor, manufacturers can gain increased performance with little redesign in systems based on existing platforms in order to improve camera and video quality. The OMAP-DM500 coprocessor has the added advantage of stacked memory, resulting in reduced board space.
The OMAP-DM500 and OMAP-DM299 multimedia coprocessors feature an ARM7 processor and TI’s most advanced Image Signal Processor (ISP) technology, including a dedicated imaging/video accelerator. Flexible interfaces support various types of CMOS sensor interfaces, signal conditioning circuits, power management, mobile DDR-SDRAM, shutter, iris and auto-focus motor controls. The devices also offer a seamless interface via SPI, I2C and parallel interfaces to application and baseband processors.
The OMAP-DM500 and OMAP-DM299 multimedia coprocessors come ready-to-use with software, enabling coprocessor enhancement to new and existing systems with minimal investment in development. Software management for the device’s programmable and dedicated image processing functions and peripherals is performed through the high-level operating system on the host processor. As part of the product, TI provides the framework and codecs that make up the baseline software. In addition, advanced still imaging and video features and applications are available from third parties, including face detection and tracking, smile detection, blink detection, red eye removal, backlight compensation, advanced image and video stabilization, as well as photo and video editing capabilities.
OMAP-DM500 and OMAP-DM299 Multimedia Coprocessors Features:
* Simplifies design of camera phones with up to 5-megapixel sensors
* TI’s latest image signal processor (ISP) technology with capability of JPEG compression up to 80 megapixels per second
* Supports up to 30-fps MPEG4 (VGA), H.264 (CIF) encode and decode
* Full support of multiple image sensors utilizing various interfaces to maximize compatibility
* Support for advanced still image stabilization and noise filtering to enhance low light performance
* High-quality video capture supported by utilizing video stabilization along with high-resolution advanced video codecs
* Seamless interface to OMAP™ application processors and other baseband and application processors
* Ready to use without coprocessor programming, minimizing risk and saving development time
* Includes TI baseline imaging and video processing software, with additional advanced still imaging and video features available from third parties
* Low power consumption extends battery operation
* Stacked memory (OMAP-DM500 coprocessor) and small form factor packaging aid mobility
Leverages TI expertise in both digital still cameras and wireless technologies.
