| // In the JVT syntax, frequently flags are used that indicate the presence of |
| // certain pieces of information in the NALU. Here, these flags are also |
| // present. In the encoder, those bits indicate that the values signalled to |
| // be present are meaningful and that this part of the syntax should be |
| // written to the NALU. In the decoder, the flag indicates that information |
| // was received from the decoded NALU and should be used henceforth. |
| // The structure names were chosen as indicated in the JVT syntax |
