Video Display Interface

Simulate display of images to video screen on device

  • Library:
  • SoC Blockset / Peripherals

  • Video Display Interface block

Description

The Video Display Interface block simulates the behavior of a video output device. This block receives image samples as messages from a connected Video Display block that simulates the video driver code connected to your algorithm.

Ports

Input

expand all

This port receives the image data as a message from the msg port of a connected Video Display block.

Data Types: SoCData

Output

expand all

The port outputs the unwrapped image matrix data as three heightwidth-element vectors where height and width are the dimensions of the image matrix defined by the Image Size parameter. The 3 is the multiplier for the RGB channels.

Dependencies

To enable this port, set the Output parameter to To output port.

Data Types: uint8

Parameters

expand all

Specify if the block acts as a terminator, similar to the Terminator block, or produces data to an output port.

Specify the height and width dimensions of the image emitted as a vector by the data port of this block. Specify custom to set custom image dimensions.

Specify custom height and width dimensions of the image matrix emitted by the data port of this block.

Dependencies

To enable this parameter, set the Image size parameter to custom.

Specify the image data output encoding as RGB or YCbCr 4:2:2 triplets.

Dependencies

To enable this parameter, set the Image size parameter to custom.

Enter the sample time defining the rate at which to receive the message containing video data.
