Introduction
TiVo is a format encapsulating MPEG-2 data.
ty format
The ty format consists of multiple chunks. Each chunk contains multiple records. Each record contains multiplexed MPEG-1 or MPEG-2 audio and video data. The multiplexing is non-standard. It looks like a mixture of a Program Stream and a Transport Stream, but lacks some features. Each ty chunk is padded with zeroes to be exactly 128kB.
tmf format
The tmf format is a tar-file that contains a blob of XML data and up to sixteen .ty files.
TiVo format
This is an encrypted MPEG-2 encapsulation used by TiVo To Go. It uses the Turing Cipher Algorithm and a device specific MAK (Media Access Key).
