BBC HD Audio sync test

INTERLACED 1080i TRANSPORT STREAM VERSION ([HD] BBC HD Audio sync test.1080i-ts.Clumpco.ts)

The Interlaced TS version is a direct recording off BBC HD. It plays fine in the latest version of VLC, but Media Player Classic has problems with it (at least with my splitter/codec combination). It might not play on your favourite player/software. Your hardware player might accept it if you rename it to a .m2ts file.

On software players you will need to activate some sort of de-interlacing in order to see the moving parts of the image correctly - try all the methods offered by your player (and graphics card - NVidia have a good de-interlacer), you will be surprised at the different results.

The Progressive 720p mkv version has been de-interlaced and recoded just like a normal HD encode. It should play on your normal HD software/hardware player. As far as I can tell the sound sync has not been affected by the encoding operation.

It will be interesting to see if any of the "recoding on the fly" streaming solutions affect sync at all.

What's it for?

The idea of this test it to check/set audio delay on your set-top box/TV/Amp combination.
Obviously if you have a set-top box that receives BBC HD you can do it yourself.
However it can be used to check for sync problems on your HD playback solution.
It consists of a repeated sound which is synchronised with 3 screen objects.

*

A vertical bar that "taps" in sync with the sound
*

3 horizontal lines that flash in sync with the sound (useful if you have some electronics experience to build a detector for the flash and the sound and to mesure the delay between them)
*

A travelling horizontal graduated bar that you can use visually to calculate delay.
