Enumerated values
Clause citations
| Value | Dec | Name | Description | History | Related |
|---|---|---|---|---|---|
| 0x00 | 0 | Not Indicated | No segmentation type is asserted. Used when a descriptor carries other information but does not itself mark a typed segment. | ||
| 0x01 | 1 | Content Identification | Identifies the content of the segment via its UPID without marking a start or end. Requires a non-zero upid type. | ||
| 0x02 | 2 | Private | A privately defined segmentation type whose meaning is agreed out of band. A general-purpose parser cannot tell you what it marks. | ||
| 0x10 | 16 | Program Start | The program begins here. Pairs with Program End to bound a program. | Pairs with 0x11. Program Early Termination (0x12) can also close the program early. | |
| 0x11 | 17 | Program End | The program ends here. | Pairs with 0x10 | |
| 0x12 | 18 | Program Early Termination | The program is ending sooner than planned. It stands in for a normal Program End when a program is cut short. | Pairs with 0x10. An early alternative to Program End (0x11) for a program opened by Program Start (0x10) or Program Join (0x19). | |
| 0x13 | 19 | Program Breakaway | The feed breaks away from the scheduled program, for example to cut to breaking news. Pairs with Program Resumption when the program returns. | Pairs with 0x14 | |
| 0x14 | 20 | Program Resumption | The program resumes after a breakaway, returning to the feed that was interrupted. | Pairs with 0x13 | |
| 0x15 | 21 | Program Runover Planned | The program is running long, and the overrun was expected, as can happen with scheduled live coverage. It tells downstream systems the program is extending past its slot. | Supports Segments but is not paired with a Start or End. | |
| 0x16 | 22 | Program Runover Unplanned | The program is running long unexpectedly. Same idea as the planned runover, but the overrun was not scheduled. | Supports Segments but is not paired with a Start or End. | |
| 0x17 | 23 | Program Overlap Start | A new program starts while the previous one is still ending, as happens when live coverage runs long. Only one overlap start may be active at a time. | Pairs with 0x11. A Program End must occur before another Program Overlap Start. | |
| 0x18 | 24 | Program Blackout Override | Supplies a fresh set of delivery restrictions for a program already under a blackout, replacing the ones in effect. It can loosen or tighten what is allowed, not only let the program through, and the applicable restrictions are resolved against out-of-band policy, which takes precedence. See clause 10.3.3.11. | Not part of a Start/End pair. | |
| 0x19 | 25 | Program Join | The station joins a program already in progress, as when it joins network coverage late. Pairs with Program End. This type was named 'Program Start - In Progress' in the 2016 through 2019a editions and renamed 'Program Join' in 2020. | changed 2020 (Renamed 'Program Join'.) | Pairs with 0x11. Program Early Termination (0x12) can also close the program early. |
| 0x1A | 26 | Program Immediate Resumption | Signals that the program resumes. Despite the name it follows the normal splice-time rules of its carrying command (see clause 10.3.3.8) rather than implying a special immediate-timing mode. | Supports Segments but is not paired with a Start or End. | |
| 0x20 | 32 | Chapter Start | Marks the start of a chapter within a program. Chapters are numbered with segment_num and segments_expected. | Pairs with 0x21 | |
| 0x21 | 33 | Chapter End | Marks the end of a chapter. | Pairs with 0x20 | |
| 0x22 | 34 | Break Start | Marks the start of an ad break as a whole (as opposed to an individual placement opportunity within it). | Pairs with 0x23 | |
| 0x23 | 35 | Break End | Marks the end of an ad break. | Pairs with 0x22 | |
| 0x24 | 36 | Opening Credit Start | Marks the start of a program's opening credits. Deprecated in favor of the Segment Content Reference for describing credits. | deprecated 2022 (Deprecated: use the Segment Content Reference (SCR UPID) to describe credits instead.) · deprecated 2023r1 (Remains deprecated in the 2023r1 edition.) | Pairs with 0x25 |
| 0x25 | 37 | Opening Credit End | Marks the end of the opening credits. Deprecated in favor of the Segment Content Reference for describing credits. | deprecated 2022 (Deprecated: use the Segment Content Reference (SCR UPID) to describe credits instead.) · deprecated 2023r1 (Remains deprecated in the 2023r1 edition.) | Pairs with 0x24 |
| 0x26 | 38 | Closing Credit Start | Marks the start of a program's closing credits. Deprecated in favor of the Segment Content Reference for describing credits. | deprecated 2022 (Deprecated: use the Segment Content Reference (SCR UPID) to describe credits instead.) · deprecated 2023r1 (Remains deprecated in the 2023r1 edition.) | Pairs with 0x27 |
| 0x27 | 39 | Closing Credit End | Marks the end of the closing credits. Deprecated in favor of the Segment Content Reference for describing credits. | deprecated 2022 (Deprecated: use the Segment Content Reference (SCR UPID) to describe credits instead.) · deprecated 2023r1 (Remains deprecated in the 2023r1 edition.) | Pairs with 0x26 |
| 0x30 | 48 | Provider Advertisement Start | Start of a programmer-owned advertisement that the programmer marks so a downstream system may replace the individual ad, typically identified with an Ad-ID UPID. | Pairs with 0x31. Uses sub-segments | |
| 0x31 | 49 | Provider Advertisement End | End of a programmer-owned advertisement. | Pairs with 0x30 | |

| 0x34 | 52 | Provider Placement Opportunity Start | Start of a placement opportunity the programmer owns and a downstream distributor may replace.
