CX23416
The CX23416 is a low-cost, low-power MPEG-2 video
and audio encoder 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 CX23416 is a highly integrated MPEG-2 audio/video encoder.
The versatile CX23416 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 dramatically reduce the cost of designing and manufacturing
their next-generation digital video products. Pre-filtering improvements
in the CX23416 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
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.
