With the emergence of HDTV, the H.264 ip camera has frequently appeared in front of us, HD-DVD and Blu-ray are plans to
adopt this standard for program production. And since the second half
of 2005 has been regarded either NVIDIA or ATI hardware decoding
acceleration support for H.264 ip camera as its video technology most worthy of boasting. H.264 in the end is where the "sacred" mean?
H.264 is a high-performance video codec technology. Current
international video coding technology to develop the organization has
two, one is "the ITU (ITU-T)", it set the standards H.261, H.263, H.263
+, etc., the other is "international Organization for Standardization
(ISO) "it sets the standards MPEG-1, MPEG-2, MPEG-4 and so on. The H.264
is formed by the two organizations jointly Joint Video Team (JVT)
jointly developed a new digital video coding standard, so it is both the
ITU-T H.264, is the ISO / IEC MPEG-4 Advanced Video coding (Advanced
Video Coding, AVC), and it will become the standard MPEG-4 part 10.
Therefore, whether MPEG-4 AVC, MPEG-4 Part 10, or ISO / IEC 14496-10,
all refer to H.264.
The biggest advantage of H.264 ip camera is a
very high data compression ratio, image quality at the same conditions,
H.264 to MPEG-2 compression ratio is 2 times more than MPEG-4 is 1.5 to 2
times. For example, if the original file size is 88GB, the use of
MPEG-2 compression standard compressed into a 3.5GB, compression ratio
of 25:1, and compressed using the H.264 compression standard into 879MB,
from 88GB to 879MB, H.264 compression ratio staggering 102:1! Why are
there so H.264 high compression ratio? Low bit-rate (Low Bit Rate)
played an important role, and MPEG-2 and MPEG-4 ASP compression
technology compared to the other, H.264 compression technology will save
the user's download time and data traffic charges. It is particularly
worth mentioning is that, H.264 high compression ratio in the fluid also
has high-quality images, and as such, through the H.264 compressed
video data, the network bandwidth needed to process less also more
economical.
