TechnoTrend Video File

TechnoTrend Video Files in the PVA format are recordings made by DVB (Digital Video Broadcasting) PCI "TV tuner" cards when tuned to television channels. These files store both the video and audio streams from broadcasts in raw MPEG-2 elementary streams, preserving synchronization and timestamps for accurate playback even if transmission errors occurred. They are useful when you have recorded TV shows with a tuner card from TechnoTrend and need to view or convert those recordings.

These files are created by TechnoTrend DVB PCI cards using their built-in recording tools. Because PVA is a non-standard container, many media players do not play it directly. Typically such a file is converted ("demuxed") into a more standard format like MPEG-2 Program Stream so it can be edited, burned to DVD, streamed, or played with common software. Tools such as FFmpeg include a PVA demuxer to perform this conversion.

According to the official TechnoTrend specification, a PVA file has no global file header or trailer. It is composed of back-to-back AV (audio/video) packets. Each packet starts with a small AV header followed immediately by a payload of either one video or one audio PES (Packetized Elementary Stream). There is only one video stream and one audio stream per file. The video packet lengths are aligned to four-byte (DWORD) boundaries. Every packet includes a synchronization value and timestamps to allow audio and video to stay in sync.
