What should I be tracking?
In the first iteration of TVPR, your implementation should track only program content and no advertisementsYou are expected to track both content and advertising. You should call the library's track-Method only once per content-stream, and once per ad(-block).
Can you summarise how your libraries work in simple terms?
All libraries for our supported platforms offer a mechanism to adapt any player for measurement (on the supported platform). The only information the library needs, is the current position on the stream in seconds. Beside that the measurement also requires the information about the stream itself (Content ID or live stream channel) and the duration of the stream in seconds ("0" for live simulcast streams).
Can you summarise how to use your libraries in simple terms?
The basic use of the library is:
1. Create once a "SpringStreams" instance which contains basic information like the sitename (required) and the application name when it's an app.
2. Choose or implement an adapter for the player or stream you want to use
3. Call the track method of the library by giving the adapter and the information about the stream itself
From this point the stream will be measured. These steps are always the same on each supported platform.

What metadata must I provide to the library?
See Player monitoring requirements. Our library needs to receive mandatory information on the current position of the stream in seconds, a stream identifier (unique BARB Content ID and/or name of the stream) and information about the stream duration if the stream is VOD not live (so-called duration of the stream).
How do identify my program content?
See Player monitoring requirements. For on-demand you must provide the BARB standard Content ID. For live, this is still being revised because it might not always be possible to supply a standard Content ID in a live context.
What should I use to populate the Content ID (cq) variable?
Please discuss this with your Project Owner who will advise you which internal code you should use.
Our Content ID contains slashes and other special characters. Does it need to be URI encoded to be sent correctly?
You don’t need to URL-encode, the library does that. It will not be truncated.
What should the duration of a live simulcast stream be?
Live streams should always have a duration of “0”.

How do I manage pre- and mid-rolls?
In most cases, it is enough to connect the Kantar library to only the content object in your player, and notconnect it separately to advertisement objects. The library will automatically keep track of the content when it is being paused for mid-rolls. You should not try to micro-manage what the library is doing. The play head position reported via the main content won't change whilst commercials are playing (it's paused during this time).

In total we could potentially have up to 11 net streams created in one session. If we were to start measuring from the first advert, the net stream created and passed to SpringStream would not be the same net stream that would be used for the actual content. We can call "stream.stop()" and then call "track()" again with new meta data and net stream, but would this be classed as the same user session? Using the above example we would be calling the "stop()" "track()" combination quite a few times. Is this correct?
Unless commercials are being specifically tracked, you’ll need to find a way to ensure that the different content parts are delivered to the library as one. There should be no calling of the stop() and start() functions, because then you will lose the UID (a random-generated session ID), and the same stream will in fact become another view. (1 view per content part, multiple views for the entire content).
