A method of controlling the state of closed-captioning in a television receiver, the method comprising: outputting from the television receiver, a video signal to a display device, the video signal carrying video data for a video presentation on the display device; outputting from the television receiver, an audio signal to an audio device that drives audio speakers, the audio signal carrying audio data that is output as audio at a first volume level value, the audio data being associated with the video data; detecting, by the television receiver, a user initiated volume adjustment operation received by the audio device, the volume adjustment operation altering the audio output by the audio device to a second volume level, wherein the television receiver repeatedly monitors for the user initiated volume adjustment operation by querying the audio device to send, to the television receiver, an audio adjustment information message containing volume adjustment information corresponding to the user initiated volume adjustment operation and receiving the audio adjustment information message in response to the query; and determining, at the television receiver, the second volume level value based at least on the detected user initiated volume adjustment operation by: retrieving a last known volume level value from a memory module of the television receiver, wherein the last known volume level value corresponds to the first volume level value; extracting volume adjustment information from the received audio adjustment information message and using the volume adjustment information and the last known volume level value to determine the second volume level value; and modifying (412, 418), under control of the television receiver, a state of closed-captioning in the video presentation based on the determined second volume level value by retrieving from a memory module a threshold value and enabling closed-captioning of the video presentation if the second volume level value is less than the threshold value, and disabling the closed-captioning of the video presentation if the second volume level value is more than the threshold value. outputting from the television receiver, a video signal to a display device, the video signal carrying video data for a video presentation on the display device;
