Description BENEFITS OVERVIEW Te l 408.523.6500 Fax 408.523.6501 .zoran. 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 Supra AV® 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 preprocessing filters, the user can shape the ining 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. .. 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 posite and S-Video signals are supported. For posite signal input, a high quality, programmable 3D Y/C separation circuit partitions the luma and chroma signals. To pensate 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...
