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.
MPEG-1 is a compression and encoding system defined by MPEG (Moving Pictures Experts Group). It creates multiple frame sequences of I, B, and P, with the I frame containing all picture data. The B and P frames only store information about the changes on the last I frame. Typically, MPEG-1 uses 1.2 Mbps data rate, which is the speed rate of CD-ROM.
