If a camcorder say its "full HD 1920x1080" is that alike as 1080p?
Answers: 1080P indicates that the frames are progressive, fairly than interlaced. Interlaced video, while traditionally viewed as better for sports, just updates parts of the frames giving a preceived higher framerate. Progressive updates the entire frame at once, similar to a traditional camera where on earth an entire picture is taken. For this, many inhabitants prefer progressive video because it give the picture a more filmesque appearance. However, progressive video have several drawbacks, including latency when shooting high-speed motion, such as sporting events or a "jumpiness" when panning a frame too prompt.
Progressive shooting for the consumer is a relatively new point and I'm sure would be advertised as such next to your new camera. If it does not speak progressive, assume that it is not. However, to most users, progressive vs. interlaced footage is a non-issue. The full HD indicates simply that the picture is not upconverted from standard definition, but is actually capture in HD which provides greater resolution and detail. Technically, HD is other compressed if it is written to tape, and when written to disc, it is compressed again. Unfortunately, blue stream or HDDVD burners are a bit away from the masses.
In summary, it is probably not progressive, but that probably shouldn't mattter. The resolution is the exact same between progressive and interlaced, merely the framerate is different.
HD is a television possession, either 720 or 1080 vertical lines next to 16:9 aspect ratio. The frame rate most common for 720 is 60p, but for 1080 it can be 60i, 30p or 24p. The number of pixels is fixed. Almost adjectives HD is MPEG2 compressed which has temporal (multiframe) compression.
Full HD 1920x1080 could connote a lot of things. It's a marketing message, not some gauge of quality. For the most cut, all the camcorders that speak they record 1920x1080 are adjectives recording 1440x1080 video and stretching the symbol to 1920x1080 for playback. While some of the camcorders are starting to have progressive copy modes, like the Canon HV20's 24p mode, for the most quantity the consumer HD camcorders record video as some form of 1080i.

All consumer HD camcorders use some quality of compression on the video. HDV camcorders typically use MPEG-2 compression. AVCHD camcorders use a version of h.264 compression.
