Techwell Introduces Two Multi-Channel Video Decoder Solutions With Embedded PCI
Express Interface to Simplify Hardware Design

SAN JOSE, Calif., Nov. 3, 2009 (GLOBE NEWSWIRE) -- Techwell, Inc. (Nasdaq:TWLL),
a leading designer of mixed signal video semiconductor solutions for the
security surveillance, automotive, and consumer electronics markets, today
announced two multi-channel video capture products, the TW6864 and the TW6868.
These devices feature Techwell's premium quality 4-in-1 video decoder technology
-- which has the best weak signal performance in the industry, four
high-performance audio ADCs, and an integrated PCI Express interface. This high
level of integration simplifies the PC DVR card hardware design and reduces
production costs.

Demonstrated at the CPSE show in Shenzhen, China earlier this week, the TW6864
and TW6868 take advantage of the significantly faster speed and overall larger
data bandwidth of the PCI Express interface -- a feature in high demand for
security surveillance systems utilizing a software compression PC DVR card.

The TW6864 and TW6868 support both real time and non-real time video and can
output multiple video resolutions including D1, half D1, and CIF, providing
maximum application flexibility. Techwell's proprietary video locking technology
enables a non-real time switching speed that is faster than competitive
products, allowing for the highest possible frame rate per channel. In addition,
both ICs contain a high-performance proprietary DMA controller that fully
utilizes the PCIe x1 bandwidth, enabling video and audio data transfer at an
optimal throughput rate.

The TW6864 can decode and transfer four channels of real time D1 video (up to 16
channels of non-real time video) and four channels of audio. In comparison, the
TW6868 can be cascaded with an external Techwell 4-in-1 decoder such as the
TW2865 to achieve eight channels of real time D1 video and 9 channels of audio.
In non-real time mode, the TW6868 (when combined with TW2865) can support up to
24 channels of video.

"The PCIe bus is becoming the dominant interface on the PC motherboard.
Fortunately, the TW6864 and TW6868 provide a versatile and scalable solution for
the software compression PC DVR card market," said David Nam, Techwell's VP of
sales and marketing. "Techwell has set the precedent for highly integrated
front-end surveillance video semiconductor solutions since 2001 and these two
new video decoder solutions demonstrate why we continue to be the market
leader."
