BBC One and BBC Two will be streamed live - just as BBC Three, BBC Four, CBBC, CBeebies and BBC News are already broadcast on their channel websites.
Director of BBC vision Jana Bennett said this "completes our commitment" to make channels available online.
The live simulcast for both channels will be available from 27 November.
If viewers miss any programmes they will be available for up to a week on the BBC iPlayer.
"From 27 November licence fee payers will be able to watch BBC programmes live wherever they are in the UK on their computers, mobile phones and other portable devices," Ms Bennett said.
According to media watchdog Ofcom, the number of people watching TV on the internet has doubled in the last 12 months.
In 2006, Channel 4 became the first major UK TV channel to be simulcast on the internet.
