Astro On Demand (Simplified as Astro AOD) is a Cantonese-language drama TV channel service co-established by TVB and Astro. It features the latest TVB drama series and broadcasts the same time as the origin channel. The channel was officially launched on 16 July 2007. Astro On Demand plays spontaneously as Hong Kong does on premiering drama series. However, not all drama series are subject to the rules above. Programming options like subtitles are available in Chinese and Malay and in recent years English subtitles and Mandarin audio option are added.
