Frameworks (2):
-
Motion JPEG: not really a standard. High-quality frame-preserving codec, relatively low compressions rates
-
Leading technology for non-linear video editing (AVID), broadcast quality video, mostly SW but HW decoders emerging. AvidNet (a.k.a. MediaNet) network support
-
Limited standardization. Recent initiatives: Digital Media Language (DML) and Open Media Framework (OMF)
-
MPEG: both a codec and delivery framework; international standard; Telcos and cable TV industry pick for network digital video
-
complex codec using both intra and inter frame compression; encoding very CPU intensive; encoding algorithm not part of the standard, both Constant Bit Rate and Variable Bit Rate supported; variable quality up to HDTV
-
system stream carries both video and audio (6 channels for MPEG-2); suitable for both disk and network delivery; difficult to handle in interactive titles
-
3 different flavors: MPEG-1, MPEG-2, MPEG-4
