# Time-shifted viewing examples in AWS Elemental MediaPackage
<a name="time-shift-examples"></a>

These are MediaPackage time-shifted viewing examples.

**Start parameters use case**  
I need content to start playing from where the customer left off.  
**Solution**: Include the `start` parameter in the playback request URL. Program your playback device to record the time that they customer stopped the stream, then use this timestamp as the value for the `start` parameter.  

**Example**  

```
...stream.mpd?aws.manifestsettings=start:1732285823
```

**End parameters use case**  
I need to define when the live content ends. Content is available for playback after this point, but live content won't be added.   
**Solution**: Ensure the **startover window** on the endpoint accurately reflects how long you want the live content to be available for playback (up to 14 days). In playback requests, include the `end` parameter and use the time that live content ends as the parameter value.  

**Example**  

```
...stream.mpd?aws.manifestsettings=end:1732300175
```

**Manifest window use case**  
I need to serve manifests of varying length from the same manifest URL because my customers use a variety of devices that have different limitations on manifest window lengths.   
**Solution**: Include the `manifest_window_seconds` parameter in playback request URLs. Use the length limitations from each device as the value of for the `manifest_window_seconds` parameter.  

**Example**  

```
...stream.mpd?aws.manifestsettings=manifest_window_seconds:30
```

```
...stream.mpd?aws.manifestsettings=manifest_window_seconds:120
```
