Under the Broadcasting Act, both buyers and sellers of unauthorised set-top decoders are liable to a fine not exceeding $40,000 or a jail term not exceeding three years, or both.

The Act also states that the lawful provider of the content may take civil action against anyone selling or using these unauthorised decoders.

Web streaming, though, is a grey area.

Mr Michael Lim, an intellectual property lawyer from Samuel Seow Law Corporation, said: "For web streams, the copyright infringement would largely fall on the side of the website owner or the person who is responsible for recording the broadcasted footage (rather) than the viewer at home.

"However, it would be a copyright infringement if the streamed footage is shown to a paying audience instead of being for personal consumption."
