On2 Technologies announces the latest hardware design - the HantroTM 8270 1080p encoder. This new design supports H.264 Baseline, Main and High Profile versions of video, as well as 16Mpixel JPEG still images. The Hantro 8270 requires minimal clock frequency requirements - less than 250MHz for 30fps 1080p video - ideal for low-power chipsets for battery-powered devices and consumer electronics.

Pre-processing features improve image quality and compression performance
The Hantro 8270 integrates proprietary technology for video stabilization and automatic scene change detection.
Its video stabilization function compensates for the effects of camera shake, which improves the quality of the captured video. In addition, the new technology analyzes each frame of the original video and then trims and repositions the frame image to remove unwanted motion. Since this process is performed before encoding, the overall compression efficiency can be improved.
Automated scene change detection brings significant advantages to real-time video surveillance, multi-camera broadcast and offline transcoding (PVR) applications, which recognize significant content changes and instruct the encoder to insert a keyframe so that Unnecessary compression distortion is removed (these distortions are typically generated in several frames due to the encoder adapting to changes in content). This technology increases the peak signal-to-noise ratio (PSNR) of posts that follow a scene change by 4 to 8 db, allowing viewers to watch transcoded content such as movies and TV shows, as well as common to multi-lens surveillance systems and live events.

Mika Hakala, senior vice president and general manager of On2 Technologies' embedded solutions, said: "Because power consumption is a key factor in semiconductor design, it is necessary to maintain a low overall clock frequency. The challenge of designing a 1080p decoder is that data must be transmitted and encoded. The required clock frequency is accepted by chip manufacturers. Through efficient pipeline applications and intelligent parallel technology with key functions, we not only meet and exceed customer expectations for 1080p video performance."
