  - encode
```
public static int encode(int gvcid,
                         int signalingField)
```
    Compute the Error Control word based on the virtual channel id and signaling field byte
    
    Parameters:
    
    gvcid - 10-bit Master Channel Identifier followed by the Virtual Channel Identifier in the lowest 16 bits of the variable
    
    signalingField - - 8 bit signalling byte in the lowest 8 bits of the variable
    
    Returns:
  - decode
