AI and NPU: A Revolution in Vantiva's Set-Top Boxes

The integration of Artificial Intelligence (AI) into the connected home transforms how we interact with technology in our daily lives. The next-generation Set-Top Boxes (STB), equipped with Neural Processing Units (NPUs), represent this technological revolution, offering even more powerful performance and processing capabilities.  

The NPU: A Pillar of Integrated Artificial Intelligence 

NPUs are specialized processors designed for AI-related calculations, enabling complex operations like machine learning and voice recognition. Unlike traditional CPUs and GPUs, NPUs are built for massively parallel computations, optimizing tasks specific to AI algorithms while reducing energy consumption. 

The power of NPUs is measured in TOPS (Tera Operations Per Second), indicating how many trillions of operations per second the processor can execute. Currently, Vantiva’s STBs reach a processing capacity of 2 TOPS, or 2 trillion operations per second, enabling tasks like video processing, voice recognition, and management of connected devices. 

Local Processing and Reduced Cloud Dependence 

One of the key advantages of NPUs is their ability to process information locally. STBs equipped with NPUs can handle AI tasks directly on the device, without needing to constantly connect to remote servers. This offers several benefits: 

• Reduced Latency: Responses to voice commands or connected device requests are almost immediate, enhancing the user experience. 

• Enhanced Security: With local processing, less of users’ sensitive data is transmitted to external servers, reducing the risk of cyberattacks. 

• Energy Efficiency: In everyday scenarios like video calls or image improvement, using an NPU-equipped device, such as a set-top box, allows local processing of complex tasks like background noise suppression, image correction, and video stream management. This setup significantly cuts energy use. The device minimizes the need for data exchange with the cloud, thereby reducing the energy spent on data transmission. By optimizing local computations, the overall energy consumption is lower compared to performing all tasks in the cloud, making it a more sustainable choice. 

This local management not only boosts performance, but also provides users with greater flexibility, offering improved responsiveness and better data protection. 

Advanced Applications of NPUs in Connected Homes 

STBs with NPUs go beyond improving multimedia streaming. Thanks to their AI processing capabilities, these devices will become central hubs in smart homes. Here are some concrete applications of NPUs in Vantiva’s STBs: 

• Advanced Voice Recognition: NPUs enable real-time analysis of voice commands, recognizing who is speaking, making interactions with home assistants and other home devices smoother and more personalized. 
• Real-time Video Analysis: NPUs can analyze video streams for home surveillance systems, triggering alerts or actions based on detected events, such as unusual movements or objects left in a room. 

• Multimedia Content Optimization: Using AI algorithms, STBs can personalize the user experience by recommending content based on viewing preferences and habits. 

Ever More Powerful Set-Top Boxes to Come 

The evolution of NPUs in STBs will radically change the connected home landscape. The current performance of 2 TOPS already supports advanced applications, but the next generation of STBs could see their power multiplied with NPUs capable of reaching up to 40 TOPS. 

This technological evolution will directly impact all tasks managed by STBs, from controlling connected devices to streaming ultra-high-definition multimedia content, with enhanced responsiveness, better image quality and much more personalization. 

Energy and Environmental Challenges 

As mentioned, the integration of NPUs in STBs not only improves performance, but also reduces energy consumption. By shifting the processing of certain tasks directly to the device, NPUs reduce reliance on remote servers and optimize the use of system resources. 

In a context where environmental concerns and reducing carbon footprints are crucial, and for all of us to continue to strive for a greener future, the energy optimization provided by NPUs becomes a significant asset. STBs equipped with this technology can operate longer while consuming less energy, a feature increasingly important to solution providers and sought after by consumers. 

Conclusion: The Future of STBs and NPUs 

With the integration of NPUs into STBs, and as technology advances towards even more powerful NPUs, Vantiva is positioning its devices as key players in the evolution of smart homes. Vantiva has already several hundreds of thousands of STBs with NPU deployed. These devices will become central hubs capable of meeting the growing demand for natural interactions between people and their digital living, bringing ease of use and ambient intelligence in modern households.
