Smart TV Test Lab
According to IDC predictions, shipment for global smart home audiovisual entertainment products will reach 457.5 million in 5 years. Among them, smart TVs have the most complete functions and are convenient for wired or wireless internet connection. On top of that, newer smart TVs are generally equipped with voice control and support various IoT device applications, which make them the core products of the smart home ecosystem.
“Smart TVs” have provided us with diversified entertainment. But do you know about the extensive time and complex testing validations that are required for a smart TV to be designed, developed, and introduced to the market? If a serious flaw went by undetected at any point during the testing process, users will have a negative impression on the product, which may impact the brand’s reputation.
Allion has more than 20 years of TV validation experience. Through the accumulated big data analysis, we learned that smart TVs on the market generally have the following four issues:
- TV Signal Interference
- Video Streaming Instability
- Wireless Signal Interference
- Voice Control Function Abnormality
Allion’s 8 Major Testing Validations for Smart TVs
Smart TVs have gradually become the center of home entertainment. By connecting to the internet, immediate streaming and connection to other IoT devices are possible, thereby creating a complete smart home ecosystem. By integrating two decades of experience in TV inspection techniques, Allion can provide in-depth analysis, suggestion, and testing validation at any point in the process to increase your product’s market competitiveness.
We can provide corresponding assistance for your smart TV at different stages of product development.

Allion has invested heavily in its laboratory testing facilities, which include a Broadcast Test Center for digital TV signal validation for emerging markets. For example, Allion has received official approval from the Malaysian Communications and Multimedia Commission (MCMC) and the Standards and Industrial Research Institute of Malaysia (SIRIM) to provide digital terrestrial TV broadcast receiver testing. Besides, Allion can also offer digital TV conformance test services for countries such as Singapore, Vietnam, Thailand, India, Australia, New Zealand, Kenya, Tanzania, and ECOWAS countries, such as Nigeria and Ghana. Allion has collected a comprehensive library of worldwide TV signal streaming data to improve product usability through scenario testing.
Allion is fully-devoted to the testing validation industry and has the world’s most complete TV signal database. Apart from providing our consumers with the newest TV signals from our frequently and regularly updated database, we are also equipped with a central signal generating system that is able to dispatch global TV broadcasting signals and digital images. It can test if the signals are operating under specific environments.
We have the most complete TV signal database in the world, allowing you to never have to take pieces of equipment around the globe to conduct field tests.
In addition to different TV signals, vendors from different nations also work with different media channels to establish built-in localized video streaming APPs in the smart TVs. By constructing a complete VPN connection, Allion is able to break the limit of space and simulate internet environments for different countries to quickly discover common connection issues such as being unable to log into the APP, delayed online video streaming, etc.
Our multi-nation VPN connection system assists you in testing audiovisual streaming platforms for all corners of the world.
When used in the same environment as other IoT devices, smart TVs may be susceptible to the interference of the various radio waves from the devices, leading to screen delays, interruptions, etc.
Allion built an RF Test Lab at all costs to perform step-by-step testing from the antenna, the module, to the end product by using diverse wireless communication technologies to discover the source of interference and help to improve noise issues and speed up your product launching process.

Built-in voice assistants in smart TVs are quite often unable to accurately perform tasks due to the interference of sound in the environment. Allion provides professional Acoustic Test Chamber which is able to control sound interference conditions and simulate user scenario. Through effective validation methods, we are able to spot the fundamental cause for low voice recognition success rates and further enhance the overall user experience.

As we enter the age of IoT, perfect interoperability between products cannot be fully ensured even if a product passes the basic function validations. In response to this, Allion has constructed a well-rounded Interoperability Test Center with the goal of helping your smart TV work smoothly with other hardware and software on the market. This will greatly reduce product return rates on the market as well as negative consumer experiences.

Smart TV menu settings are constantly-updating and the application layout is getting complicated. This might cause more usability issues, for example, latency, misspelled wordings, or display problems after update. Allion’s UX/User experience optimization service designs a series of human-machine interaction testing procedures based on different product attributes. By analyzing user behavior and perceived satisfaction, we provide a reference for vendors in optimizing their software design through real-life user scenarios.
Allion’s AI Solution Has Got What You Need
Repeated validations and analyses are indispensable in Smart TV ecosystem. However, for language complexity and software quality management issues, tests which are conducted manually often take too much time and effort.
Allion integrates AI-enabled tools like Visual Recognition, Smart Navigation, AI Automation, and Big Data Analysis to increase the consistency, accuracy, efficiency, and scalability of Smart TV validation. Allion’s AI Solution can be applied to various fields, such as internationalization (i18n) testing, software quality assurance (SQA), and voice assistant testing.
Overview of Professional Testing Instruments
Besides the above-mentioned testing validations, we own the industry’s most complete instruments for testing smart TVs which can perform comprehensive professional testing and analysis based on your product’s features.
