CX23417

Description

The CX23417 is one of the industry's lowest power MPEG-2 audio/video encoders. The versatile CX23417 actually incorporates the functionality of 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 reduce dramatically the cost of designing and manufacturing their next-generation digital video products. Pre-filtering improvements in the CX23417 include built-in noise filters that dynamically improve images in the pre-processing stage. As a result, end-users obtain the best possible picture, even as the data rate is reduced and the recording time is lengthened. Other video quality improvements include an increased motion search range, the de-coupling of motion estimation from encoding, and an adaptive quantization scheme. To reduce the overall cost of the CX23417 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.
