AT73C238 application field and working principle

Introduction

The AT73C238 is a highly integrated device consisting of a six-channel, audio/video processor operating at 8 MHz to 41 MHz with an analog or digital audio stream sub-system for audio/video systems. It provides a very high degree of integration and flexibility for multimedia audio/video applications. The AT73C238 also includes an onboard embedded processor interface that allows custom application specific programs to be developed to add custom features to end-user products such as noise reduction, automatic gain control, sound and voice enhancement.

Application Fields

The AT73C238 is ideal for use in a variety of different audio/video applications such as digital signal processors, video streaming, picture-in-picture applications, broadcast solutions, low-power portable solutions and embedded signal/audio processor systems. It also has the capability to process multiple different audio/video formats such as Dolby Digital, Dolby Pro Logic II, Dolby AC-3, DVD-Video, DVD-A, DVD-Audio and HD-DVD. The AT73C238 is capable of handling digital video up to 1080i HD resolution, and can internally drive up to 6 channels of analog audio. The AT73C238 also includes an onboard media format recognition engine that provides for automatic detection of audio/video input formats and output formats as well as multi-zone and multi-source audio/video systems. The embedded ARM processor can be programmed to perform various processing functions such as noise reduction, automatic gain control, gain normalization, bass boost, treble boost, 3D Surround sound and other advanced audio effects.

Working Principle

The AT73C238 is a single-chip audio/video processor for an audio/video system. It is based on a 32-bit embedded media processor core, which seamlessly integrates digital and analog audio interfaces, digital video encoder and decoders, video scaler and video graphics processor. At the core of the AT73C238 is a 32-bit, low-power and high-performance media processor with a dedicated hardware accelerator blocks and hardware-assisted video decoder. The processor core controls all internal audio/video processing including Dolby Digital, Dolby Pro Logic II, Dolby AC-3, DVD-Video, DVD-A, DVD-Audio and HD-DVD. It also manages the external video interface, scaler and video encoders and decoders, as well as the audio loops for all functions.The AT73C238 supports several audio/video input interfaces such as HDMI, DVI, RGB, Composite Video/S-Video, and also supports several digital input formats such as Dolby Digital, Dolby Pro Logic II, Dolby AC-3, DTS, MPEG and WMA. The AT73C238 also supports multiple digital output formats such as Dolby Digital, Dolby Pro Logic II, Dolby AC-3, DTS, MPEG and WMA. Additionally, it supports analog audio output as well as surround-sound and digital subwoofers.

Conclusion

In conclusion, the AT73C238 is an exceptionally powerful, low-power and high-performance audio/video processor, specifically designed for integration into audio/video systems. It provides a high degree of flexibility, configurability and integration with existing audio/video systems and offers a wide range of features and functions.
