Explanation
Digital Video Broadcasting – Handheld (DVB-H) is a technology designed with the primary purpose of delivering live television broadcasts and multimedia content to portable devices such as mobile phones, tablets, and handheld digital televisions. The main goal of DVB-H is to provide viewers with a seamless, high-quality experience even while on the move.
By leveraging existing Digital Video Broadcasting (DVB) standards with additional error correction and optimization features, DVB-H enables reliable, real-time transmission of video and audio data with minimal interruptions caused by signal loss or fading, which are common issues when users are in motion or in areas with poor signal reception. DVB-H is particularly beneficial in situations where individuals are unable to access static digital television broadcasts, such as during travel or in densely populated urban areas where signal interference is more prevalent.
Furthermore, this technology allows for the efficient use of available bandwidth, enabling multiple channels to be streamed simultaneously without compromising quality. By bringing live television and multimedia content to portable devices, DVB-H has revolutionized the way people consume entertainment, news, and information, offering them greater freedom, flexibility, and access to the content they desire – anytime, anywhere.
Through dedicated DVB-H enabled devices or adapter accessories, users can watch their favorite shows, live sports events, or breaking news updates while also enjoying the convenience and portability their handheld devices provide.
Examples of Digital Video Broadcasting – Handheld
Digital Video Broadcasting – Handheld (DVB-H) is a technology designed for broadcasting television content to handheld devices like mobile phones, tablets, and portable media players. DVB-H allows users to watch live television, news, sports, and entertainment while on-the-go. Here are three real-world examples of DVB-H technology:
Italian Mobile TV service: In 2006, Italy became the first country to launch a commercial DVB-H service called “3 Italia.” This mobile TV service allowed users to access live television channels and other multimedia content on their DVB-H enabled mobile phones. By 2008, 3 Italia had over 1 million subscribers, showing the interest and demand for mobile TV services.
Nokia N92 and N77 Mobile Phones: Nokia, a leading mobile phone manufacturer, introduced DVB-H enabled smartphones like the Nokia N92 and N77 models. These smartphones allowed users to watch live TV broadcasts directly on their mobile devices. The devices had inbuilt antennas and DVB-H receivers to provide a seamless mobile TV experience.
ESPN Mobile TV: In 2007, ESPN launched a mobile TV service in the United States called ESPN Mobile TV. The service used MediaFLO, a competing mobile television broadcast technology based on DVB-H, to deliver live sports content to mobile devices. ESPN Mobile TV offered live broadcasts, video-on-demand, and highlights to sports enthusiasts on their mobile devices.While DVB-H technology made significant headway during its early years, it eventually faced stiff competition from other mobile TV technologies and rapidly evolving mobile internet capabilities. This led to the decline of DVB-H in favor of streaming video services and apps using the mobile internet.
