Video Encoding High-quality real-time encoding (I-, B-, and P-frames) Supports MPEG-2 and - 525/60 (NTSC) 30 fps - 625/50 (PAL) 25 fps HDTV MPEG capture Variable and constant bit rate to 15-Mbit/sec Programmable GOP lengths Adaptive field/frame (motion compensation type 8 DCT) Field/frame motion estimation - B-frame: ☑84(V) - P-frame: ☒02(V) - Half-pel accuracy to 4:2:0 conversion Speckle noise reduction Sharpness control Recursive noise reduction Inverse telecine (3:2 pulldown) Scene change detection Adaptive quantization Supports elementary program, and transport streams Automatic VBI extraction Conexant provides complete software support for the CX23416, including an on-chip API function call layer and binary and source code examples. To reduce the overall cost of the CX23416 and achieve the highest video quality, Conexant devoted significant engineering resources to determining the optimal balance between hardware and software implementation of these processing improvements. Other video quality improvements include an increased motion search range, the de-coupling of motion estimation from encoding, and an adaptive quantization scheme. As a result, end-users obtain the best possible picture, even as the data rate is reduced and the recording time is lengthened. Pre-filtering improvements in the CX23416 include built-in noise filters that dynamically improve images in the pre-processing stage. The versatile CX23416 actually incorporates the functionality up to three different chips, allowing Conexant to deliver this device at a price point that will enable consumer electronics and personal computer companies to dramatically reduce the cost of designing and manufacturing their next-generation digital video products. The is a highly integrated MPEG-2 audio/video encoder. Conexant's broadband communications portfolio includes a comprehensive suite of semiconductor solutions that enable the digital home and information network.
