MPEG-4

MPEG-4 standard breaks down complex multimedia data into individual video and audio objects. Each object comes from synthetic or natural environment. An effective encoding method is used for every different object type.  

Ateme provides MPEG-4 encoder and decoder for Texas Instruments C64x and DM64x families and for PC platform.
Pre- and post-processing tools are also available to build your video application.
Ateme’s MPEG-4 encoder is declined in 3 configurations: from the "MPEG-4 Simple" to the “MPEG-4 Advanced” encoder configuration, Ateme algorithms offer you the opportunity to address the right multi-media solution for your application.

Applications: Multimedia applications, Internet appliances, video-security systems, video-phone, consumer equipment, video servers, etc.

MPEG-4

MPEG-2  

A complete software solution developed by Ateme for the 'C6000 DSP family. MPEG-2 fully satisfies the need for high quality images. It is a flexible algorithm in terms of evolution with lasting quality. MPEG-2 on DSP architecture is a well-adapted solution for embedded real-time systems.
The MPEG-2 video elementary stream decoder is re-entrant (xDAIS compliant).

MPEG-2 is easily customized in terms of I/O format, image outlet latency, memory optimization, audio decoder, etc...

Applications: Digital Television set top boxes, Cable TV Distribution, Video on Demand, Cable Digital Distribution, Cable Digital Audio Distribution, Digital Sound broadcasting, Serial storage media (DVD players etc.)

MPEG-2

JPEG/Motion JPEG

This baseline implementation of JPEG and Motion JPEG standards is fully optimized for both the C5000 and the C6000 Texas Instruments DSP families. Every JPEG parameter and bit stream feature is user-defined, making this algorithm very flexible in terms of performance, cost and time-frame targets. Our solution supports extensions in terms of lossless, progressive or hierarchical encoding,... Moreover it requires no external memory and no calls to DMA features.

Applications: Observation systems, video-security, medical imaging, vision, UAV, portable equipment, cameras, ...

JPEG/Motion JPEG

H263

This imaging compression algorithm is dedicated to low bit-rate video imaging applications. 100% software solution for 'C6000 DSP family, H263 allows low cost DSP architecture for embedded real-time systems. Its main advantages are: Flexible evolution, ease of maintenance and possibility to integrate additional functions (e.g. audio, modem).
H263 software supports extensions and options in terms of H263 standard appendices, transmission protocol

Applications: Video conference, video-security, video-phone, Internet applications, ...

H263

H264

H264 standard corresponds to MPEG-4 Advanced Visual Coding (MPEG-4 AVC)
This standard is declined in 3 profiles:Baseline, Main, Extended

The main changes are:

•  Integer transform

• Context Adaptive Coding (CAVLC, CABAC)

• Enhancement of every steps

• H264 coding will require far more processing power

Roadmap
Rich of their experience in video compression codecs development (MPEG-4, MPEG-2, H263, JPEG …), Ateme development teams are currently working on H264 codec.
