Abstract: This technology relates generally to television set-top-boxes (STBs), and more particularly to sharing program information between STBs using voice communication. In one embodiment, a method of sharing television (TV) program information between STBs is disclosed. The method includes obtaining, by a control unit, program-specific-information of TV content selected by a first user using a first STB. The program-specific-information may be converted into a voice message by a Text-to-Speech (TTS) converter. The method further includes establishing, using a first Subscriber Identity Module (SIM) associated with the first STB, a voice call from the first STB to a second STB. The voice message associated with the program-specific-information may be transmitted from the first SIM to a second SIM associated with the second STB over the voice call using a first modulation scheme.
