Marek TV

Marek TV is an application to watch analog TV. The history of the program starts around 1997 when I started programming BT848 RISC TV chip. I ended up with fully working device driver (including DMA transfer, software teletext decoder) and optimized real time MJPEG encoder (I rewrote JPEG's IDCT - inverse discrete cosine transform for AMD's 3D now SIMD instruction set). The latest version uses Direct Show to support all the codecs and all the hardware (it is a great benefit but it was much less fun to code comparing to the first version where I had to program everything).

Features:
  • supports any TV tuner (through Direct Show)
  • video recorder (AVI, h264 encoding)
  • TV listings
  • teletext
  • no CPU usage on PCI cards (DMA transfer)
  • software decoder for Nagravision 1 scrambling system (video & sound, obsolete)
  • video backup system (tv output required, obsolete)
