Television sets have served as the centerpiece of household entertainment for decades. They are capable of receiving broadcast signals from wired and wireless TV stations, and displaying audio and video signals transmitted by external devices (such as STBs and DVDs) through various analog and digital interfaces. In 2007, the first generation of networked smart TVs came into being, representing a new, innovative paradigm for TV products. Smart TVs could run a wide variety of apps, and enabled consumers to watch live and on-demand video directly from the Internet. They also allowed TV content to be actively selected, a big departure from the passively-received nature of traditional TV content. In addition, smart TVs supported signal reception (wireless and wired), as well as a wide range of digital/analog interfaces, network interfaces (wireless and wired), audio/video signal processing methods, and image displays.
Similar to how mobile phones now far exceed basic communications capabilities thanks to the emergence of smartphones, smart TVs have developed in much the same manner, no longer only serving as a media and entertainment center, but also an information sharing center, a household control hub, and a medium for human-machine interaction. The latest generation of smart TVs offers superb audiovisuals, supporting 4K/8K content, premium audio, and high dynamic range (HDR) content, while also integrating AI cameras and neural-network processing units (NPUs) to provide diverse network access capabilities such as WiFi and Bluetooth. Their main processors now integrate high-performance CPU, GPU, NPU, 4K/8K codec, image signal processors (ISP), as well as premium audio digital signal processors (DSP). Notably, the HiSilicon smart TV solution supports our proprietary HiStreaming technology, which enables smart TVs to quickly identify any peripheral devices that also support HiStreaming, implement seamless connection for lower latency and higher safety, and support structured transmission of AI data. This allows peripheral devices to be virtually operated and controlled as local devices, delivering the best possible experience to every member of the household.
HiSilicon has been researching and manufacturing smart TV SoCs for almost a decade, and millions of TVs around the world already use HiSilicon technologies to provide consumers with optimal audiovisual quality. As the global leader in the smart TV SoC sector, HiSilicon offers a full range of smart TV SoCs that support HDR, AI picture quality (AI-PQ), motion estimation/motion compensation (MEMC), and a wide range of different resolutions, from full high definition (FHD) to 4K/8K. All HiSilicon solutions support HarmonyOS, Linux, Android, and other mainstream operating systems. In addition, HiSilicon SoCs come equipped with the following peripheral chips:
A set-top box (STB) is a media device connected to a TV. It decodes audio and video signals which are then sent to the TV, compensating for the TV's data processing and app extension shortcomings. There are currently two types of STBs on the market: Internet Protocol Television (IPTV) STB and over-the-top (OTT) STB. IPTV STBs provide live streaming services through a carrier-controlled private network, while OTT STBs achieve this through the public Internet. As restricted by relevant policies, OTT STBs can only provide live streaming services after a third-party app is installed. All types of STBs consist of logical modules such as those related to network connections, digital signal processing, and video signal output.
As artificial intelligence (AI) and the Internet of Things (IoT) continue to rapidly advance, STB functions have evolved from simply decoding audio and video to gradually encompassing all major smart home features, such as camera capabilities, ultra-high-definition (UHD) encoding/decoding, access technologies such as WiFi and Bluetooth, high-quality audio playback, and local video display. Modern STBs are now capable of the following functionality:
No longer a mere decoding chipset, the STB SoC can now integrate high-performance CPU, NPU, UHD codec, ISP, and premium audio DSP.
Recent years have seen online videos become a major cultural phenomenon, with a diverse range of attractive content — including short videos and live streaming — more accessible than ever before. With such a wide variety of content and varying daily routines, it becomes difficult to satisfy the entertainment needs of an entire household with just a single TV screen. The intelligent STB has been developed as a remedy which integrates high-quality audio and video output devices to provide more convenient and flexible video playback modes for consumers. In addition, with the high-performance CPU, GPU, NPU, ISP, and DSP, the intelligent STB is a suitable entry for implementing smart home controls.
HiSilicon launched its first STB SoC in 2007. Over the past decade, HiSilicon and its partners have blazed a trail in such fields as HD, intelligence and 4K/8K, and hundreds of millions of STBs based on HiSilicon SoCs have now been brought online. In addition to providing high-quality audio and video services for consumers, they also represent highly reliable and easy-to-manage solutions, capable of serving multiple carriers. HiSilicon STB SoCs feature industry-leading image quality enhancements, alongside robust system performance, while certain mid- and high-end products integrate the Da Vinci AI NPU module and support in-depth integration into the HarmonyOS ecosystem. By offering diverse external interfaces and working with camera and WiFi chips, our SoCs provide consumers with seamless home connections and smart home services.
