+# Deltacast Videomaster Receiver
+
+This application demonstrates the use of videomaster_source to receive and display video streams from a Deltacast capture card using Holoviz for visualization.
+
+## Requirements
+
+This application uses the DELTACAST.TV capture card for input stream. Contact [DELTACAST.TV](https://www.deltacast.tv/) for more details on how to access the SDK and setup your environment.
+
+## Build Instructions
+
+See instructions from the top level README on how to build this application.
+Note that this application requires to provide the VideoMaster_SDK_DIR if it is not located in a default location on the system.
+This can be done with the following command, from the top level Holohub source directory:
+
+```bash
+./holohub build --local deltacast_receiver --configure-args="-DVideoMaster_SDK_DIR=<Path to VideoMasterSDK>"
+```
+
+## Run Instructions
+
+### C++ Application
+
+From the build directory, run the command:
+
+```bash
+./applications/deltacast_receiver/cpp/deltacast_receiver
+```
+
+### Python Application
+
+From the build directory, run the command:
+
+```bash
+python3 applications/deltacast_receiver/python/deltacast_receiver.py
+```
