    Audio Capture The audio capture engine is responsible for receiving de-embedded audio data, via an I2S interface, formatting the data and transferring it into on-board memory. The module receives two channels of audio data, at a 48 KHz rate, organized as 24 bits of left channel data and 24 bits of right channel data.
  • Page 13 Pixel Buffering The pixel data formatted by the video capture engine is stored into two on-board FIFO memories. This memory serves as an elastic store for formatted video pixel data. The FIFOs are managed by an independent pair of controllers, implemented in the FPGA, supporting concurrent operation.

  • Page 34: Color Space Converter Dialog

    Color Space Converter Dialog The Color Space Converter dialog allows the user to adjust the behavior of the color space conversion function. This function is responsible for converting from YCrCb video data to the RGB-24 format. Note that if either the YCrCb-20 or YCrCb-16 mode is selected, then YCrCb data is delivered from the card into host memory and therefore the color space conversion function is performed by software.

    RGB Control Dialog The RGB Control dialog allows the user to adjust the gain and offset for each of the RGB color components. Optionally, the gains can be set automatically by invoking a white balance function. Note that if either the YCrCb-20 or YCrCb-16 mode is selected, then YCrCb data is delivered from the card into host memory and therefore the RGB control function is performed by software.

  • Page 37: Rgb Lookup Table Dialog

    RGB Lookup Table Dialog The RGB Lookup Table feature allows the user to modify and transform the original video data. The pixel values for each of the R, G and B components can be mapped into new values. The mapping from input to output values is defined in a lookup table ( LUT ) file.
