Data Item Type Allocation and Registration

This page contains the publicly accessible administrative register of Data Item Types for SMPTE ST 2110-41. Allocation of entries in this registry is purely administrative and Data Item Type values shall be registered for any request containing all of the required information below. Each Request is for a single Data Item Type registration. Several kinds of Data Item Types can be requested as descripted below.

1. SMPTE Data Item Types 

The Data Item Type range 0x000000 through 0x0FFFFF is reserved for allocation by SMPTE for Data Item Types associated with SMPTE Technical Documents.  The Data Item syntax and semantics of such types shall be defined by a SMPTE Technical Document.  The registration information for such a type shall include: 

  • the Data Item Type (number) allocated by SMPTE HQ 
  • brief textual description 
  • reference to the defining SMPTE technical document or section thereof 

2. Other User Organization Data Item Types 

The Data Item Type range 0x100000 through 0x1FFFFF is reserved for allocation by SMPTE for Data Item Types requested by other user organizations.  The registration information for such a type shall include: 

  • the Data Item Type (number) allocated by SMPTE HQ 
  • brief textual description 
  • reference to the defining technical document or section thereof 

Requests from other user organizations for allocation of ranges of contiguous values require the consent of the SMPTE Standards Vice President; allocation of such a range does not relieve the requesting organization from the requirement to submit individual requests for registrations of values with the required information as they are needed. 

3. Private Data Item Types 

The Data Item Type range 0x200000 through 0x2FFFFF is reserved for allocation by SMPTE for Data Item Types requested by individuals and corporations.  The public registration information for such a type shall include: 

  • the Data Item Type (number) allocated by SMPTE HQ 
  • brief textual description 
  • A contact name and email address for information purposes 
  • (Optional but highly encouraged) URL or other reference to a defining document 

The registrant may provide a URL or other reference to a defining document, but is not required to do so. 

4. Reserved Data Item Types 

The Data Item Type range 0x300000 through 0x3FEFFF is reserved for future use. 

5. Experimental Data Item Types 

The Data Item Type range 0x3FF000 through 0x3FFFFF is for experimental use.  These Data Item Types may be used on an experimental basis during the development of new formats and applications without the need to register.  It is incumbent on the users of these values to ensure that their use does not interfere with other users.
