Abstract:
1. A processor-implemented method for audible channel announcement comprising: using a processor: detecting displayed channel information corresponding to a current program channel decoded for display by a display screen; wherein when the broadcast video is an analog signal, the detecting is based on detecting a discontinuous timing or momentarily black section in the analog video signal; and wherein when the broadcast video signal is a digital video signal, the detecting is based on detecting data corresponding to the channel information in a channel watermark in an area of the digital video signal with relatively static contrast; capturing, in response to said detecting, the channel information; parsing the channel information to determine the current program channel by: providing an audible announcement of at least one of the current program channel and network information, based on the text-to-speech translation, to a visually impaired user, wherein the network information includes a broadcast network identity that corresponds to the current program channel and that is determined by a user location and by a service provider identity; wherein detecting the channel information comprises detecting data corresponding to the channel information in closes captioning data.
