# Industry Separation

You can apply industry separation in advertising breaks on a per-break basis. To enable industry separation, each on-demand call must include:

- a **break ID** (**[break-id](/v1/docs/ad-request-parameters#break-id)**) to identify the break;
- a **break context** string (**[Break-Context](/v1/docs/ad-request-parameters#break-context)**) provided by Triton Digital.

### *How Industry Separation Works*

The first on-demand ad request must include the **break ID** to identify the ad break. The response from Triton Digital includes categories and advertisers that provide the **break context** in the form of IAB information in the response headers. Subsequent on-demand requests for the same break *must also include the break ID plus the last break context that was returned in the response header*. The IAB categories and advertisers identified in that response header will be excluded from the any further responses directed towards the identified break.

There is capping logic embedded in **ad pods**, but you can use the**break-id**and**Break-Context**parameters to apply industry separation *between ad pods*. For more information, see [Ad Pod Usage Notes](/v1/docs/ad-request-parameters#ad-pod-usage-notes).

### *Passing the Break ID and Break Context*

The information below describes how the break ID and break context are passed.

**The break ID you provide in the request:**

- Must be a universally unique identifier ([UUID](https://en.wikipedia.org/wiki/Universally_unique_identifier)).
- Must be unique per listener.
- Is mandatory if you want to use industry separation.
- Is **automatically reset** by Triton Digital when a request is received that does not contain a break context. (I.e., after a series of requests containing a break context, if the next request does not contain a break context, then the break ID is assumed to be different and is reset.)

**The break context from Triton Digital:**

- Is *reset* by Triton Digital when we receive a different break ID.
- Is encoded as a **character string** to to be sent back, as-is, with your next ad request.
- Includes the break ID, IAB category, and advertiser ID for responses that have been returned within the same break.
- Requires no special development effort on your side.
- Is **ignored** by Triton Digital if it is invalid.

The **preferred way** to return the break context is via the**[Break-Context](/v1/docs/ad-request-parameters#break-context)****header parameter**, although it can also be passed via the**break-context**query parameter.

#### Sequence Example

The example below shows the sequence using *query parameters*, as this is easier to illustrate. **Triton Digital strongly recommends using header parameters instead.**

**Call 1: break-id = test803**

`https://xxx.live.streamtheworld.com/ondemand/ars?stn=CTH_DEMO_04&type=midroll&lsid=12365465&break-id=test803`

**Result:** Break context is returned, encoded with category by advertiser.

- Break-Context header:  
`eyJicmVha0lkIjoidGVzdDgwMyIsImluZHVzdHJ5Ijp7IklBQjgtMyI6MTExMX19`

**Call 2: break-id = test803 + previous break-context (returned for call 1)**

`https://xxx.live.streamtheworld.com/ondemand/ars?stn=CTH_DEMO_04&type=midroll&lsid=12365465&break-id=test803&break-context=eyJicmVha0lkIjoidGVzdDgwMyIsImluZHVzdHJ5Ijp7IklBQjgtMyI6MTExMX19`

**Result:** Break context returned with accumulated categories and advertisers.

- Break-Context header:  
`eyJicmVha0lkIjoidGVzdDgwMyIsImluZHVzdHJ5Ijp7IklBQjgtMyI6MTExMSwiSUFCOC00IjoxMTExfX0=`

**Call 3: break-id = test803 + previous break-context (returned for call 2)**

`https://xxx.live.streamtheworld.com/ondemand/ars?stn=CTH_DEMO_04&type=midroll&lsid=12365465&break-id=test803&break-context=eyJicmVha0lkIjoidGVzdDgwMyIsImluZHVzdHJ5Ijp7IklBQjgtMyI6MTExMSwiSUFCOC00IjoxMTExfX0=`

**Result:** Break context returned with accumulated categories and advertisers.
