Audio/video system for TI's DaVinci
technology
Ateme's EASEE simplifies development and reduces time to market enabling developers to benefit from all the various capabilities of TI's DaVinci technology.
DaVinci technology is tailored for digital video applications, providing optimised software, development tools, integrated silicon and support to simplify design and facilitate innovation TI's TMS320DM644x devices based on DaVinci technology are highly integrated system-on-chips (SoCs) and include both TI's performance-leading TMS320C64x+ digital signal processor (DSP) core and an ARM926 processor

Ateme has produced a version of its H.264 decoder for embedded platforms, complementing the PC version released in June.
Interoperability test participant promotes MPEG
Ateme, a provider of hardware and software solutions for audio and video compression on DSP, PC and FPGA, has participated in MPEGIF's MPEG-4 AVC interoperability tests.
EASEE takes advantage of both cores to provide one complete system.
The Software System running on Linux resolves all lip synch issues and responds to the requirement for compression, streaming over IP and file containers.
EASEE is composed of: a framework, based on the GStreamer core coming from the open source market that Ateme ported to DaVinci technology; a complete set of audio and video compression and decompression algorithms - standard streaming protocols; and the most common file containers.

Development platform has educational aims
The EmbestUniversity is a teaching platform focused on embedded system development.
The framework enables developers to construct the skeleton of the application in the form of a processing graph.
Individual components such as input and output drivers and processing elements are connected together to work on a flow of data.
Both simple and complex processing graphs can be designed to fit any kind of project.
The designer can focus on what the application has to perform and the framework makes it happen.
The suite of audio and video codecs enables a developer to build any kind of multimedia applications including recorders, players and streamers.
On the video side, H.264, MPEG-4, DivX, MPEG-2, WMV9 decoders and H.264, MPEG-4 encoders are already available.
On the audio side, AAC, MP3, MPEG-1 Layer 2 and voice codecs can be added on either the ARM or the DSP.
To interface with the network/Internet, several streaming protocols have been developed including TCP/IP, RTP/RTSP and MPEG-2 TS.
For those who require store or playback features from a hard drive, the need for file multiplexers and demultiplexers has been fulfilled with AVI, MP4, MPEG-2 PS, EXIF.
With all the elements that compose EASEE, developers can easily design any type of digital video equipment.
Applications ranging from video security, video conferencing, IP set top box, portable media players, digital media adapters and many others can be efficiently achieved on DaVinci technology using EASEE.
"With DaVinci technology, TI has combined the performance of a DSP with the open structure of an ARM, running Linux, to deliver a flexible SoC optimised for video applications", said Marc Guillaumet, Business Unit Manager, Ateme.
"Thanks to our experience on audio/video systems on DSP, we have taken the full benefits of this architecture to build a rich and flexible software solution as user-friendly as a PC".
