Product Brief  
Description  
BENEFITS OVERVIEW  
1394/DV camcorders using the DVD recorder remote  
control. This feature facilitates an integrated environment for simple  
editing and archiving of home movies.  
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  
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.

SupraAV 100, the Activa 100 offers a flexible solution of  
STB/DTV+HDD/PVR products for the cable and satellite markets.  
MPEG VIDEO ENCODER  
VBI BIT SLICING AND DECODING  
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.  
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.  
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.  
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.  
PROGRAMMABLE AUDIO DSP  
The programmable audio DSP encodes in real-time Dolby Digital  
Consumer Encoder (DDCE), MPEG1-L2, MP3, and WMA formats.  
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.  
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
