The E-TDA7479D is a cutting-edge integrated circuit specifically geared for linear video processing. The device can be used in a plethora of applications and is suitable for analog, digital and even HD video processing, making it a versatile and multi-functional component of choice for many designers. This publication aims to provide readers with an extensive yet concise description of the device and its utility both in terms of its application field and its working principle.

Application Field

The primary application field of the E-TDA7479D is linear video processing, specifically within the field of professional-level audio-visual (AV) systems. It can be employed to deliver both high-performance and cost-effective solutions to designers and engineers who are looking to create or enhance analog, digital and HD video systems. These systems are often employed in video broadcasting, surveillance, large-format video projectors and other related applications.The E-TDA7479D is a high-speed CISC microcontroller which can achieve a maximum clock frequency of up to 25 MHz. The device further supports a number of external linear video processors, including timing and control receivers, frame combiners and single-chip modulators. It can also be used to provide resolution independent video processing, a capability that sets it apart from some of the other linear video processing solutions available.The E-TDA7479D\'s capabilities also extend to support a wide range of video input formats, including NTSC, PAL, SECAM and HDTV. In addition, it offers features such as programmable scaling capabilities, multi-standard audio encoding, OSD generation and motion detection. These features make the E-TDA7479D an ideal component for applications where linear video processing needs to be performed in the most efficient and economical manner possible.

Working Principle

The E-TDA7479D is based on the principle of linear video processing, which is one of the most commonly used techniques in analog video systems. Linear video processing involves four major steps: acquisition, processing, analysis and display.The acquisition step is the initial phase, which requires the video signal to be digitized. This is done by a device known as an ADC, or Analog-to-Digital Converter, which is used to convert the analog signal into a digital equivalent which can then be processed.The processing step involves sending the digitized signal to a filter, the purpose of which is to remove any unwanted noise and artifacts from the signal. This ensures that only accurate information is passed on to the next step.Once the signal is free from noise, it is ready to undergo the analysis phase, which involves the application of various video processing algorithms to the signal in order to augment its quality. These algorithms may include scaling, color correction, compression, de-interlacing and other techniques.The last step is the display step, during which the signal is finally ready for viewing. This is achieved by means of a video encoder, which is responsible for converting the processed signal into a format which can be displayed on a suitable display device.

Conclusion

The E-TDA7479D is a highly-specialized, multi-functional integrated circuit which is primarily intended for linear video processing applications. Its extensive features and capabilities enable it to be used in a number of professional-level. AV systems, including video broadcasting, surveillance and projector systems. It is based on the principle of linear video processing, which requires four major steps: acquisition, processing, analysis and display. As such, it is a great choice for applications that require efficient and economical video processing.
