HD5 (Singaporean TV channel)

HD5 was a Singaporean free-to-air television channel that was launched as the high-definition version of Channel 5. The channel was the first HD broadcast on DTT in Southeast Asia. HD5 aired 10 hours of HD-produced series each week, including movies, dramas, and original productions made by Mediacorp.

In late 2013, Channel 5 HD was launched on DTT and aired simulcast programming with Channel 5's SD feed. Due to national availability of Channel 5 HD, HD5 was shut down on 1 October 2017

History
Mediacorp trialled its HDTV service on digital UHF channel 38 under the brand name MediaCorp HDTV in July 2006. The service broadcast from 9pm to 11pm to an audience of 1,000 households with at least one LCD television set capable of receiving HD signals. With a schedule of 14 hours per week, MediaCorp HDTV in this phase carried American TV series already filmed in high definition and a handful of feature films.

A year later, in July 2007, these broadcasts became regular, adopting the brand name HD5. The new channel was a simulcast of Channel 5 with the entirety of its programmes aired in digital format.
