hello to everyone

just today was with my pc capturer for Digital TV recorded sme files and analyzed with mediainfo, just found that one TV channel broadcas now with HE AAC V2 which is weird because the ISDB-Tb system do not contemplate this codec version for broadcast the HE-V2 s i weird besides looks like are broadcasting in multichannel or perhaps dolby pulse which is already more weird yet .
here the info that gives mediainfo just weird , it was they broadcasting an movie the pirates of the caribbean 2 and just is like weird that now they uses HEV2 codec for audio

best regards

Francisco

HE AAC -LC as codec just with such channels technical broadcasts disparities is just hard even to me setup my system correctly

also the 5.1 audio yeah perhaps could be used but not in the legacy dolby digital, rather in the dolby pulse which no receiver supports that format.

here is an explanation for dolby pulse
