eEver & Etron Tech Joint Launch the New Generation Stream Processor Unit (SPU) – EJ523D Audio/Video Signal Processor, Supports Ultra-High-Definition Video Capture Up to 4K2K 60FPS It Can Be Applied in Various Innovation Applications such as Audio and Video Streaming

Many audio and video streaming applications are springing up with the rapid evolution of cloud services, 5G networks, artificial intelligence (AI), and big data technologies. The demand for data processing and high-speed transmission capabilities has increased dramatically. To meet these demands, eEver Technology and Etron Technology (TPEx: 5351.TW) today (May 16) introduced a new audio/video signal processor, the SPU – EJ523D. The EJ523D is a dual-channel audio/video processor that supports HDMI signals and can perform a variety of signal processing tasks on-chip, such as compression, scaling, format conversion, and audio mixing. After processing, the final output can be USB. The product supports up to 4K2K 60fps and 1080P 120FPS Ultra HD video capture and streaming. It can record signals from various sources such as smartphones, camcorders, set-top boxes, DVD/BD players, and game consoles, greatly expanding the possibilities of existing audio and video streaming applications. Several leading system customers have already adopted this design, and system products will be available soon.


Introducing the innovative SPU heterogeneous integration chip product is significant for Etron. “The application of audio and video streaming technology presents many new business opportunities. The launch of the SPU-EJ523D audio and video signal processor opens up more possibilities for multiple signal switching and convergence, audio and video streaming applications, and business models. In addition to the EJ523D single chip, Etron Innovation’s Known Good Die – the bare-die memory chip can also be used to form heterogeneous integrated chips and sub-system platforms, helping a diverse range of customers to develop new systems rapidly, and supply growing Data and A/V streaming applications. It is an honor to be at the forefront of this innovative SPU. The EJ523D is expected to provide strong technical support for various audio and video streaming applications worldwide, facilitating the rapid growth of audio and video streaming,” said Dr. Nicky Lu, Chairman and CEO of Etron Technology and eEver Technology Inc.


As audio and video streaming technology continues to evolve, more innovative applications are emerging, including live eSports, live product sales, video conferencing, telemedicine, industrial remote assistance, and training, etc. Audio and video signal processors are critical when switching or combining multiple audio and video signals. HDMI is the standard output format for many audio and video devices. The new generation audio and video signal processor SPU-EJ523D can be easily connected to various audio and video sources for streaming using the USB 3.2 gen1 port and any HDMI device such as smartphones, computers, or game consoles. It converts audio and video input signals to USB output signals and transmits them to PCs, laptops, smartphones, and tablets. With support for 4K2K 60FPS HD video quality, it can adapt to different platforms for image capture and live streaming to meet various application needs. In addition, the EJ523D also features audio signal mixing and other functions, further enriching its application in multimedia production and transmission, making it the best solution for capturing ultra-high-definition audio and video and post-production.


“We are proud to introduce this innovative SPU audio and video signal processor. This SPU audio/video signal processor – EJ523D is born from an insight into the evolving audio/video industry and a deep understanding of the market needs. It will provide powerful technical support for various audio and video streaming applications worldwide with its ultra-high quality image capture, streaming, and easy connection to various audio and video sources. It is expected to drive the diversified applications and rapid development of audio and video streaming.” said Shihmin Hsu, vice president of eEver.



The EJ523D, which supports 4K2K 60fps and 1080P 120FPS Ultra HD image capture and streaming, offering a wide range of powerful audio and video features. It supports Scaler for scaling image streams of different resolutions, Picture-in-Picture (PIP) for overlaying image signals to increase visual richness, 1080P 120FPS for smoother image performance with a higher refresh rate, Mirror for image mirroring and flipping functions that can solve the problem of left-right inverted images in video conferences, and high-quality audio signal Resample, which can convert audio sampling rate up to 24bit 192KHz, Mixer to mix the external microphone’s sound into the HDMI input audio for multiple sound source combinations, and other functions. In addition, the powerful compression engine can do H.264/H.265 compression, facilitating image storage and streaming. By flexibly combining these processing capabilities and integrating the chip with artificial intelligence (AI) technology in the next-level device, advanced audio and video processing functions can be more efficiently realized, such as intelligent monitoring, automatic tracking, and intelligent clipping.


With the rapid development of the streaming market, the SPU – EJ523D from the company will bring huge potential and commercial value to various industries. It is expected that the EJ523D will quickly be adopted in various application areas, such as self-media production, online education, e-sports broadcasting, e-commerce, enterprise video conferencing, remote industrial management, and telemedicine. The appearance of the EJ523D will greatly improve the convenience of capturing audio and video signals from various sources. Its audio and video processing capabilities can enhance the overall system performance, reduce user costs, and bring users a smoother and higher quality viewing experience.
