First Claim
Patent Images
1. A method of preventing audio artifacts at a speaker, the method comprising:
- detecting an audio halt in an audio stream;
selecting one of a plurality of silent tones to embed into the audio stream at the audio halt based on an entity to which the audio stream is being sent;
embedding the selected one of the plurality of silent tones into the audio stream; and
transmitting the audio stream to the speaker across an audio bus.

Abstract
Systems and methods for handling silence in audio streams are disclosed. In one aspect, a transmitter detects a halt in an audio stream. After detection of the halt in the audio stream, the transmitter embeds a silence signal into the audio stream and transmits the silence signal to associated receivers. The associated receivers may respond to the embedded silence signal by “playing” silence or by using the silence signal to activate a silence protocol. In either event, the associated receivers do not receive the original audio halt and do not produce an unwanted audio artifact.

8. A host comprising:
-
a bus interface configured to be coupled to an audio bus; an audio halt detector configured to detect an audio halt in an audio stream; a transmitter coupled to the bus interface and configured to receive the audio stream from the audio halt detector; a multiplexer configured to embed one of a plurality of silent tones into the audio stream at the audio halt; and a control system configured to select the one of the plurality of silent tones based on an entity to which the audio stream is being sent. - View Dependent Claims (9, 10, 11, 12, 13, 14)
