摘要： Disclosed is an audio follow video mixer incorporating a manual cross fade learn feature. According to the invention, an operator may set the mixer so that a crossfade operation performed manually is stored in memory. The stored crossfade operation can thereafter be recalled and performed in an AUTO mode and an EDITOR mode. Also disclosed are LED indicators to visually indicate the status of the mixer, including which channel is active.

摘要： Disclosed is a method and apparatus for configuring an audio follow video mixer used to process audio signals input from several multi-channel devices, such as VTRs. Input modules of the audio follow video mixer include a selection button for choosing the number of a VTR coupled to the mixer module and an LED display for visually indicating the VTR number to a user. The input modules also include buttons for selecting the audio channel of the selected VTR, as well as the preview bus for the selected audio channel.

摘要： Disclosed is an apparatus for configuring an audio follow video mixer used to process audio signals input from several multi-channel devices, such as VTRs. Configuration of the audio follow video mixer system can be achieved either through several input modules which couple the multi-channel devices to the mixer, or preset configurations can be provided to the input modules and remotely located devices, such as a video editor, through a serial interface module.
