Synapse TV adds five new services to the Freeview EPG
Africa Free TV on channel 248 will be the home to a portal of channels from Africa, operated by the same organisation that runs Vision TV on channel 244. Its launch date is yet to be determined, according to Synapse TV and details of the channels it will carry are yet to be disclosed.
Synapse 1, 2 and 3, which are now on channels 249 to 251 are placeholders to be used for the testing of new services prior to their launch.
In the adult section, channel 184 is a new simulcast of the satellite service Sin TV, delivered via broadband internet to compatible connected devices and is already available to viewers.
These channels are known as streamed or hybrid channels. These channels are distributed via broadband internet and are accessed via the terrestrially transmitted Freeview EPG. Synapse TV is one of two providers of such services. Arqiva's Connect TV has also signalled an expansion in the number of channels it provides to viewers, with recent Ofcom licences for hybrid services taken out for ABN TV and Passion TV. (Update 08/07/2015: ABN TV has confirmed it's launching on channel 252 on 16th July.)
