2012 was called "the first year of smart TV". In this year, Chinese domestic brands such as TCL and Skyworth, Japanese brands such as Sony and Sharp, and Korean brands such as Samsung have launched smart TVs. Unlike traditional TVs that only focus on image processing performance, smart TVs are more like a computer. In addition to high image quality and 3D display, an operating system is also installed. The TV can be managed through various programs to achieve video on demand, Internet surfing and other applications. Therefore, compared with traditional TV chips, smart TV chips require not only high-performance image processing ICs, but also high-performance application processors to run various complex programs. In a sense, the level of processor performance will directly determine the future market prospect of smart TVs. At present, more and more international processor manufacturers have entered the smart TV chip market. High-performance, multi-core cores have become the development trend of smart TV chips.
Application processor manufacturers march into smart TV
The development trajectory of smart TV and mobile device chips are getting closer and closer, and Intel, Qualcomm, Marvell and others have entered this market one after another.
As a new generation of smart TVs will support higher-end operating systems, with naked-eye 3D display, ultra high-definition (4k) display, multi-screen interaction, and even advanced functions such as somatosensory and voice control, the requirements for processor performance continue to increase. Smart TV and mobile The trajectory of the device's chip is getting closer and closer. In order to fully optimize the design of smart TV functions, since 2012, large processor manufacturers such as Marvell, Intel, Qualcomm, Nvidia, Apple, and Samsung have entered this market one after another.
Qualcomm has cooperated with Lenovo to develop high-end smart TV K91 through its 4-core Snapdragon S4 chip; Google ’s Google TV ’s first-generation chip is provided by Intel, the second-generation chip supplier is Marvell, and Lenovo ’s smart TV S31 has also chosen to use Marvell platform. Mobile processor companies are rapidly emerging in the TV market.
Shen Jin, global vice president of Qualcomm ’s business development and general manager of Qualcomm Ventures China, said that smart TV is Qualcomm ’s newly expanded industry. Qualcomm believes that the focus of exploring smart TVs is "multi-application", making TVs a truly interactive device. In order to get the approval of consumers, young people can return to the living room and the TV market can have a new look.
Multi-core CPU and graphics processor become the dominant solution
The processor industry has launched a multi-core CPU and GPU solution to enter the smart TV field with the same series and different levels of IC.
Because the industry characteristics of broadcasting and TV are different from mobile terminals, mobile chip manufacturers have not been able to copy the technology to the field of TV chips. However, with the cultivation of user habits by mobile internet, the mobile user experience has gradually been brought into TV applications. Therefore, some mobile terminal chip factories have begun to make some technical changes on their original chips and apply them to TVs.
However, the transformation of TV manufacturers to smart TVs requires chip manufacturers to be more open in technical support. Gartner senior analyst Michele Evans Reitz said that as the demand for smart TV processors from dual-core and above is more intense for TV brand manufacturers, application processor manufacturers are bound to develop in this direction, launching multi-core central processing units (CPUs) and graphics processors ( GPU) design scheme, cut into the field with the same series, different levels of IC.
Dai Hongjun, a senior industry analyst at the China Taiwan Council of Information Technology (MIC), believes that smart TV multi-core processors will be unveiled in 2013. The basic specifications include upgrading the CPU to dual-core and a frequency of 1.2GHz to meet high-speed Internet access and diversified human-machine interfaces Applications; GPUs have also begun to move towards dual-core, providing more powerful graphics processing functions than video codec engines.
Generally speaking, the smart TV chip contains two parts: Internet browsing and video encoding and decoding. Network applications are biased towards mobile device processor functions, responsible for web browsing, digital processing, and execution of application programs; video coding and decoding are mainly based on image processing engines, with calculation methods that comply with national broadcast signal standards to smoothly edit video decoding.
From multi-screen interaction to triple play
The multi-screen integration between mobile phones and TVs depends on the connectivity of client devices such as home gateways, which in turn forms a new trend of triple play integration.
The rapid development of smart terminal devices such as smart phones, tablet computers and smart TVs has made multi-screen interaction between smart terminal devices a popular technology. Color TV companies in China are committed to developing multi-screen interactive functions and applications for their smart TV products. System operators are also actively developing systems and terminal products with three-screen interconversion to achieve the true integration of content, network and terminal. The multi-screen integration between smartphones, PCs, tablets, and set-top boxes depends on the connection of home server and gateway, OTT Internet TV / Android / HTML5 and other network client devices, thus forming a new trend of triple play.
Charlie Lou, product group manager of Broadcom's Broadband Communication Group's set-top box product line, said that the industry's current focus is how to establish an interface with a set-top box for display on a large screen, so that the set-top box can display the same content as a tablet or smartphone. The market is currently considering several multi-screen applications. The basic application of this type of interconnection is to use a smartphone or tablet to control the set-top box. More advanced applications include conversion or transcoding of set-top box videos for playback on smartphones and tablets. The realization of multi-screen applications needs to solve some problems, mainly how to establish a physical interface between the set-top box and smart phones, tablet computers. Broadcom believes that WiFi will become the physical connection between set-top boxes and mobile devices.

Unclear value chain positioning affects smart TV market growth
The factor affecting the penetration rate of the smart TV market is the lack of network and content distribution. First, we believe that the value positioning of smart TVs is unclear. The smartphone has a built-in 3G wireless network. However, smart TVs in China need to be connected to a modem; smart TV manufacturers do not provide such devices. In China, service providers such as telecom operators or cable TV operators provide modems. Therefore, smart TVs need to rely on third-party services to make them less attractive. Second, due to the lack of a service provider network, high-quality video content distribution cannot be guaranteed. Therefore, for consumers, buying a smart TV has no advantage over buying a set-top box.
The injection of new capital is expected to have a favorable impact on China's next-generation broadcast and television network (NGB) plan, which aims to build an advanced network of converged telecommunications networks, the Internet, and television networks that supports analog transmission, digital transmission, and broadband Internet access. In turn, this transition will drive the demand for high-definition set-top boxes (STB) and two-way network equipment. In the Chinese market, cable TV service providers mainly provide these equipment to users.
Broadcom is ready to meet this demand. Through cooperation with Chinese partners and set-top box manufacturers, we have defined and designed a dedicated set-top box that meets the needs of the Chinese market, and has realized productization. Set-top box chips can provide higher-quality services for a series of open Internet (OTT) -based services, while reducing the retail prices of these devices in emerging markets. In addition, we also introduced the Ethernet Data Coaxial Cable Transmission (EoC) chip that complies with the China Cable Data Service Interface Specification (C-DOCSIS), which is authorized by the State Administration of Radio, Film and Television of China. Our C-DOCSIS EoC chip provides Chinese cable TV operators with cost-effective high-speed solutions-broadband speeds of up to 1Gbps can provide converged communication services.
