Well DVDs outselling BLU RAY does not matter to me people are easily pleased,my post was not completely inaccurate but partly saying 250 lines which is back to VHS days,standard DVD is SD though and putting 30 or so min of BBC HD on dvd in avchd format means nothing as that is HD
As for AVCHD being BLU RAY standard Blu-ray uses a MPEG4 compression. It's using the
H.264 codec. Most blu-ray players can read up to 40Mbps. This is a lot of data per sec.
The AVCHD codec is heavily compressed. It's like trying to cram a beach ball into a garden hose. There's a lot of artifacts as well, which will only degrade the overall image quality. The max bit rate for this codec is usually 22-24Mbps. Most modern cameras use the H.264 codec and compress their video to a max of 48Mbps. This is double the amount of data then that of the AVCHD codec.
Can both H.264 and AVCHD do full 1080p (1920x1080), yes but the way the files are compressed is the difference.
Stop digging a hole. AVCHD is H264/AVC the self same codec (often abbreviated to AVC, H264, or AVCHD) as to being superior. HD broadcasting uses exactly the same codec. Despite the container being transport stream, the actual content is the same as the .m2ts output from a HD camcorder.
AVCHD - H264/AVC - AVC) is the most advanced variant of mpeg4 there is. AVC stands for Advanced Video Codec (advanced as in superior to mpeg 4). Also used on bluray see the link below.
H265 (HEVC) used for 4K is the only codec so far that is more efficient.
As to your last question, as H264 and AVCHD are the same codec, yes of course they can.
