The newest version of DAB/DAB+/T-DMB middleware from Factum Electronics AB is now available on Analog Devices low-power Blackfin BF5xx processors.

According to the companies, pairing the Blackfin processor with Factum middleware enables a single-chip module that brings DLS (dynamic label segment), SLS (slideshow), and EPG (electronic programme guide) data services together with audio-, image- and video-decoding capabilities for handheld mobile receivers and kitchen radios with displays or screens.

Factum's complete range of middleware modules for data services reduces development time for receiver manufacturers and support receiver stability and quality of service. Offerings include FIC (fast information channel), DLS, SLS, EPG, TPEG (transport protocol experts group) and BWS (broadcast Web site).


Delivering Signals to the DAB Transmitter

In early 1999, CHUM radio was granted DAB licenses for its two stations, CFUN(AM) and CHQM(FM), in Vancouver. The two signals had to be delivered from the studios in Vancouver to the CBC transmitter site on Mount Seymour in North Vancouver.
