Yes. All UK Freeview HD (DVB-T2) broadcasts use the adaptive progressive/interlaced switching encoder profile. This will dynamically switch between 1080/25p and 1080/50i encoding on a GOP-by-GOP (I believe) basis - allowing material shot 1080/25p (but carried in a a 1080/50i wrapper) to be detected and compressed more efficiently.
This confused a lot of early DVB-T2 TVs here - particularly Sony sets which would sound glitch on the format change.
Currently the same channels on DVB-S2 are using standard 1080/50i permanent encoding (albeit with MBAFF interlaced encoding)
