High Resolution High Definition
From Wikipedia, the free encyclopedia
HRHD (High Resolution High Definition) (also HR or HR.HDTV) is an acronym, often seen as part of the filename of TV shows shared on the Internet. HRHD TV is also referred to as Half Resolution High Definition as it is half the resolution of the original 1920x1080 (1080p) transmission.
It refers to a standard of encoding video, meaning that the video signal was ripped directly from a HDTV broadcast, then down-sampled to approximately 960x540. While the horizontal resolution of 960 remains constant the vertical resolution can fluctuate up to 5% to provide clean cropping.
A HRHD encoding for a 40-55 minute TV show should be approximately 700MBs. It contains the original AC3 sound, which is often 5.1 channels, instead of the reencoded MP3 stream found in 350MB releases.
