Description
BENEFITS OVERVIEW
The Activa 100 MPEG A/V Encoder is optimized to deliver a high
quality, cost-effective A/V encoding solution. The Activa 100
integrates DV25 decoding, MPEG A/V encoding, and analog video
decoding onto one chip. Coupled with the Activa 150, the Activa 100
enables a powerful class of DVD recorders, with optional hard disk
drive. This chipset is also the basis for Zoran’s home media center
and enables a new category of emerging applications and
connectivity for the networked digital home. Coupled with the
SupraAV® 100, the Activa 100 offers a flexible solution of
STB/DTV+HDD/PVR products for the cable and satellite markets.
MPEG VIDEO ENCODER
The MPEG Video encoder supports real-time encoding into MPEG-1
and MPEG-2 formats. With programmable spatial and temporal pre-
processing filters, the user can shape the incoming video to optimize
the MPEG encoding. The horizontal decimator allows for a wide
range of horizontal encoding resolutions: 352, 360, 480, 544, 704,
and 720. Programmable horizontal resolution, along with the bitrate,
gives the best flexibility in optimizing the encoded video quality
versus storage time.

During encoding, features such as automatic scene change detection
and variable/constant bit rate processing, consistently deliver optimal
video quality over a variety of input video.
When used in tandem with Activa 150, the Activa 100 enables the
watch and record class of applications, where the user can watch
one program while recording another. In addition, Zoran has enabled
PVR (timeshifting and pausing live TV) not only on HDD, but also on
DVD-RAM, DVD-RW, and DVD+RW media.
PROGRAMMABLE AUDIO DSP
The programmable audio DSP encodes in real-time Dolby Digital
Consumer Encoder (DDCE), MPEG1-L2, MP3, and WMA formats.
DV25 A/V DECODER
The DV25 decoder decompresses the 1394/DV camcorder input
from the 1394phy/link. The decoded data can be transcoded real-
time to MPEG-2. This chipset provides convenient, direct control of

1394/DV camcorders using the DVD recorder remote
control. This feature facilitates an integrated environment for simple
editing and archiving of home movies.
ANALOG VIDEO DECODER WITH 3D Y/C, TBC
The proven embedded analog video decoder supports decoding of
NTSC, PAL, and SECAM TV signals. Inputs of composite and
S-Video signals are supported. For composite signal input, a high
quality, programmable 3D Y/C separation circuit partitions the luma
and chroma signals. To compensate for video artifacts from unstable
sources such as a VCR, a robust time-base correction circuit
re-synchronizes the video signal prior to the MPEG encoding
process.
VBI BIT SLICING AND DECODING
The Activa 100 offers a programmable circuit for hardware Vertical
Blanking Interval (VBI) bit slicing. Hardware VBI bit slicing is
important for extracting closed captioning, electronic program guide
(EPG), Teletext, widescreen signaling, and other VBI standards
efficiently, without burdening the CPU.
DVD AUTHORING
Using the Activa 150 DVD authoring software, the Activa 100 allows
real-time archiving of home movies from DV tape onto DVD disc or
hard disk. Formatting to DVD-R/-RW/-RAM/+R/+RW is supported.
All logical formats for DVD recording, DVD+VR, DVD-VR, and
DVD-Video are supported.
INTERFACES
The Activa 100 has a glueless interface to Activa 150. A number of
1394 link+phy chips can gluelessly interface to Activa 100. To enable
digital transrating (re-encode video to a lower bit rate), 8-bit ITU-656
digital inputs can be fed back from Activa 150 digital outputs.
APPLICATION PROGRAMMING INTERFACE
For quick time to market, the Activa 100 is accessed via a simple but
powerful application programming interface. Parameterized
commands such as start encode and stop encode enable OEMs to
develop a rich feature set for digital recorder products.
