Though televisions have been able to receive a wireless signal, often referred to as an over-the-air signal, for years, wireless television takes that concept and applies it to subscription-based services. These services have traditionally depended on wires, traditionally coaxial cable and more recently HDMI for high definition signals. However, with the advent of thinner and lighter sets, prompting different placements for sets, wireless television has become a bigger need.
The latest standard in wireless television is known as Wireless Home Digital Interface, or WHDI. This technology was developed by a number of different companies, who came together to come up with a single standard they hope will be used across the entire industry as the technology starts to gain a foothold among consumers. The companies that have worked to come up with the standard for wireless, high definition digital television include: Sony, Hitachi, Motorola, Samsung, Sharp and AMIMON.
Like with any new technology or concept, there are sure to be competitors. One of those mentioned is Apple, which is developing a wireless television concept known as Apple TV™, formerly known as iTV™. This wireless digital TV concept in this case depends on a transmitter known as an AirPort Extreme™. This is based on the Wifi technological standard known as 802.11(n). Whether this standard sponsored by Apple will actually become a major competitor to the WHDI system is still unclear.
