Checking streams

Read the results

Every check writes its results straight into the channel grid, into the details of each channel and into the console. This lets you see at a glance which channels work, how good they are and which ones need you. Follow these steps to read the results.

Steps

  1. Open the Checker: Open your playlist and click Checker in the row of tabs under the top bar.
  2. Read the summary on top: Four boxes show how many channels are Working, Not working and Not checked yet, and when the Last check ran and the next one runs. Click a box to list only those channels below; click it again to see all. Next to them, Groups — worst first shows each group with a bar of how many of its channels work; click a group to open it. Under the boxes, Since the last check names the channels that stopped working or work again. Hide summary folds it away and the list gets the room.
  3. Look at the grid: Each row shows a status dot at its left and the columns Quality, FPS, Reliability, Latency and Last check. Point at a column name to see what it means.

  1. Filter by status: Click Online, Offline or Not checked above the grid. The number next to each shows how many there are. Click All to see everything again.
  2. Open a channel: Click a channel to see its details on the right: the status with quality, frame rate, codecs and resolution, and the Reliability bar with the number of checks it passed, for example 34 of 36 checks.
  3. Open the statistics: Click the console bar at the bottom of the editor, then click Stats.

The columns

ColumnWhat it tells you
Status dotGreen is online, red is offline, grey is not checked yet.
QualityThe resolution the stream delivered, for example 720p. 1080p and 4K are coloured.
FPSThe frame rate. 50 is smooth for sport, 25 is normal TV.
ReliabilityThe share of checks this channel passed. Green is 95% or more, orange 70% to 94%, red below 70%.
LatencyHow fast the stream answered. Green is under 800 ms, orange under 2,000 ms, red slower. Streams that answer slowly tend to buffer.
Last checkHow long ago it was tested, for example 2h ago.

Tip: Click Columns above the grid to add Res (the exact resolution), Audio (the sound codec) or Last played (when a customer last watched it). Click Legend to see what the colours of the dots and rows mean. Under Colours in the columns it also explains the column colours: Quality 4K and 1080p stand out; Reliability green 95% and up, orange 70–94%, red below 70%; Latency green under 0.8 s, orange under 2 s, red slower; Audio 5.1 and 7.1 stand out.
