Abstract
In one embodiment, a multimedia audio inserter removes the left and right audio channel data from a multimedia signal, for example an HDMI® signal and replaces it with an alternate audio signal, which may be the center channel audio signal provided by a digital surround sound receiver. In exemplary applications, the resulting, modified multimedia signal may be provided to a digital television that is part of a surround sound system, enabling the television to play the center channel signal through its speakers. Optionally, the multimedia audio inserter may provide a copy of the multimedia signal at a multimedia feedthrough output. In exemplary applications, the multimedia feedthrough output may be used to play left and right channel audio, present in the HDMI® signal, through dedicated left and right speakers.
Claims20
A multimedia audio inserter comprising:
- a de-audio device configured to receive a first multimedia input signal, separate the first multimedia input signal into one or more audio signals and one or more video signals, and to output one or more de-audio signals, the de-audio signals comprising the video signals and fewer than all of the audio signals;
- and
- an audio injection device coupled to the output of the de-audio device and configured to receive alternate audio signals and combine them with the one or more de-audio signals to form a modified multimedia signal.
A multimedia audio inserter comprising:
- a multimedia input configured to receive a multimedia input signal;
- a de-audio device coupled to the multimedia input and configured to remove one or more existing digital audio data channels from the multimedia input signal to form a de-audio signal;
- an audio input, configured to receive an alternate audio signal;
- an audio injection device coupled to the output of the de-audio device and configured to insert the alternate audio signal into the de-audio signal in place of the one or more existing digital audio data channels to form a modified multimedia signal;
- a multimedia output coupled to the audio injection device and configured to communicate the modified multimedia signal to a first audiovisual display device;
- a multimedia feedthrough output, coupled to the multimedia input and configured to communicate the multimedia input signal to a second audiovisual display device;
- a system power input, coupled to the de-audio device and the audio injection device
- a status indicator, configured to indicate the status of one or more of the system power, the multimedia input and the audio input.
A method for inserting alternate audio data into a multimedia signal comprising:
- separating the multimedia signal into existing audio signals and one or more video signals;
- and
- inserting the alternate audio data in place of one or more of the existing audio signals to form a modified multimedia signal.
