Technical realisation of signing in digital television
In this issue
This Report describes practical solutions for closed signing in regular TV programmes, which include the provision of two video signals, one with and one without the signer or alternatively the transmission of the signer video as additional stream.
Described techniques allow the viewer to select between the TV programme with or without the inserted sign-language interpreter. The TV programme with the inserted signer is transmitted either in the broadcast multiplex or offered via the broadband Internet.
