µPD61153B, µPD61154B
Single-Chip Solution of MPEG Encoder ICs with Analog Video-Capture Function
Features
The new system LSI chips, product names µPD61153B and µPD61154B, have embedded on a single chip an MPEG2 encoder including following four functions, which make them a perfect single-chip solution for PCs to capture high quality analog video signals. In addition, the µPD61154B chip supports Dolby® Digital audio encoding capability.
- Three-dimensional (3D) luminance/chrominance (Y/C) separator
- Video decoder
- MPEG2 encoder
- PCI™ interface supporting 4-channel direct memory access (DMA)
Overview
The µPD61153B and µPD61154B devices are single-chip solutions that capture high-quality analog video signals in digital video recording and playback devices in consumer DVD recorders and multimedia personal computers.
Target System
- Free-to-air digital TV capture card for PC
- Video capture cards for computers
- TVs with PVR capability
