A TP format is a BTTS (Beyond TV Transport Stream) file. In simple terms, it’s a transport stream for sending MPEG-2 or MPEG-1 data over the internet or using a cable. TP files are recorded using TV recorders like Dvico TViX and can open on popular programs like Apple QuickTime and Windows Media Player.
M4A is a filename extension for AAC container format and is developed by Apple Inc. M4A music is bought on the iTunes Store and does not come with DRM protection. In terms of quality, M4A is better than MP3 because it is lossless but still compressed. This means that it occupies less storage space and doesn’t lose quality over time.
