CIMM DEFINITION: In broadcasting, digital subchannels are a means to transmit more than one independent program at the same time from the same digital radio or digital television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called multicasting. (Source: Wikipedia.org)

Instead, it requires a collective industry-wide commitment and CIMM is the conduit for which the industry can articulate their needs and steps required to decide a best path forward through collaborative, data-driven research.”
