Islington Borough Council's interactive digital TV trial is to undergo more testing as the authority decides to extend the pilot scheme launched in April.
A council spokesperson said: "The pilot has been extended and eventually it is something we want to give to the whole borough, so it needs to be done gradually over time."
The pilot project saw 100 council-owned homes connected by a 10Mbps ethernet connection offering email, community TV channels and online services. The council said this could eventually be extended to more homes.
Its aim is for the service to reach all 30,000 council homes in the borough.
"This is a big project and will be rolled out as and when," said the council spokesperson.
