Digital TV Labs 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 800MHz 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 antenna 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.

Equipment

Digital TV Labs has been appointed to provide conformance testing for receiver manufacturers wishing to meet Freeview Australia specification for the Freeview MHEG-based EPG.

Equipment

The company’s new ISDB-T Evora iSuite can directly test against the Brazilian receiver specification.

Equipment

As the first HbbTV registered test center, the company will provide a fast and efficient service to deliver an official HbbTV test report.

Transmission

A small-scale trial has indicated that 4G interference to digital terrestrial TV services may be much less serious than had been expected.
