CX23415

Convergence Video MPEG Encoders/Codecs MPEG-2 Codec CX23415 The CX23415 is a low-cost, full-duplex MPEG-2 codec that integrates the functionality of several ICs in a single device Conexant’s broadband communications portfolio includes a comprehensive suite of semiconductor solutions that enable the digital home and information network. The CX23415 codec is the industry’s first device to integrate such features as MPEG-2 audio/video encoding and decoding, Transport stream generation, and OSD control in a single chip. The versatile, full-duplex CX23415 actually incorporates the functionality of up to five 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 CX23415 include built-in linear filters that dynamically change or soften 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 a dramatically increased motion search range, the de-coupling of motion estimation from encoders, and an adaptive quantization scheme. To reduce the overall cost of the CX23415 and achieve the highest video quality, Conexant devoted significant engineering resources to determining the optimal balance between hardware a...
