The BirdDog 4K SDI turns 12G-SDI into NDI and NDI back into SDI or HDMI. It has two 12G-SDI connectors, and each one works as an input or an output. It also has one HDMI 2.0 output and encodes or decodes up to 4Kp60. Showcaller AI connects to the BirdDog 4K SDI through the Bridge App on your show network. Then you run it by voice or chat. For example, say “put the stage camera on the foyer screen”. The [BirdDog NDI converter integration](/integrations/birddog-ndi-converter/) page lists every Tool Function.

### The BirdDog 4K SDI as a decoder

In decode mode, the converter turns an NDI stream back into SDI. First, Showcaller lists the NDI sources the converter can see. Then it connects the decoder to a source by name. Because a switch changes what is on screen, Showcaller asks you to confirm it. After the switch, it reads the decode status to check the new source. It also tells you which source is on the decoder right now. If a source is missing, Showcaller refreshes the list on the converter. These functions are in every plan.

### SDI to NDI encode settings

In encode mode, the converter sends an SDI signal to the network as NDI. From the Pro plan, Showcaller reads and changes the encode settings. BirdDog lists the stream name, bitrate mode, video format, tally and NDI audio among them. Showcaller also sets the NDI group name, the discovery server and the NDI transport, such as TCP, UDP or multicast. In addition, it switches the video output interface between SDI and HDMI and sets the analog audio gain. After a change, Showcaller reads back the group name, discovery server, output interface and audio settings. However, encode settings and transport are reported as the converter answered.

### Mode changes and recovery

Showcaller reads whether the converter is in encode or decode mode. However, BirdDog reports that switching the mode over its API does not work on the 4K SDI. So change the mode on the converter’s web page, BirdUI. With Enterprise, Showcaller resets the NDI source list, restarts the video engine or reboots the unit. It asks you before each of these steps.
