Digital TV Labs launches 4G LTE interference susceptibility test for Freeview receivers

Digital TV Labs mitigates UK DTT Freeview receiver test for 4G LTE interference

Digital TV Labs, the digital media testing company that specialises in testing tools and services for validating digital media and device conformance, has launched a service that enables Freeview receivers to be tested for susceptibility of interference from 4G LTE mobile services.

The new 4G services broadcasting in the 800 MHz band can interfere with both Freeview DVB-T and Freeview DVB-T2 terrestrial reception in some areas. To prevent service disruption a special filter is required between the antennae and receiver of the households that are affected. A series of tests have been specified in the latest UK D-Book specification to ensure a basic level of immunity on DVB terrestrial receivers and Digital TV Labs is now able to provide manufacturers with a comprehensive 4G LTE test service.

Keith Potter, CEO of Digital TV Labs, says, “The introduction of 4G means faster, more reliable mobile internet services for consumers but it can also disrupt some Freeview services. By validating Freeview receivers’ immunity, manufacturers can avoid potential disruption to end user TV experience.

“We’ve been providing testing services for Freeview receivers since early 2010 and provide test reports to manufacturers as part of the Freeview certification process. This latest development is another important addition to our services.”

Digital TV Labs works closely with manufacturers and operators in the consumer electronics supply chain including silicon tuner and demodulator chip suppliers. With test labs in Bristol, UK, and Hong Kong, the company facilities are ideally placed to service the majority of the consumer electronic suppliers in South East Asia. Digital TV Labs is unique in providing testing services globally for DVB-compliant terrestrial receivers.
