ATSC Tuner. 1080P Up conversion output. HDMI output R/F in and out. Dolby Digital 6 hour recoding on DVD. Overall, this is a good unit that does what it needs to do at a reasonable price. It does take some time to learn how to use this unit, and some things are not intuitive, so be sure to sit down and actually read the manual as you do things. This unit has a DVD recorder and a VCR--which is handy for transferring old videos to DVD.
