#### 8.7.8.2 Selected Transfer Syntax

The Selected Transfer Syntax is the Transfer Syntax selected by the origin server to encode a single message part in the response.

The origin server shall first determine the Selected Media Type as defined in Section 8.7.8 and then determine the Selected Transfer Syntax.

If the Selected Media Type was contained in the Accept Query Parameter, then the Selected Transfer Syntax is determined as follows:

1. Select the value of the Transfer Syntax parameter of the Selected Media Type, if any;

2. Otherwise, select the value of the Transfer Syntax in the Transfer Syntax Query Parameter, if any;

3. Otherwise select the default Transfer Syntax (see Table 8.7.3-2, Table 8.7.3-4 or Table 8.7.3-5) for the Selected Media Type.

If the Selected Media Type was contained in the Accept header field, then the Selected Transfer Syntax is determined as follows:

1. Select the Transfer Syntax parameter for the Selected Media Type, if any;

2. Otherwise, select the default Transfer Syntax for the Selected Media Type.

### Note

1. The Selected Transfer Syntax may be different for each message part contained in a response.

2. Implementers may use a different selection algorithm if the result is the same.
