MPEG2 - an overview | ScienceDirect Topics
MPEG-2 was instrumental, through its inclusion in all set-top boxes for more than a decade, in truly underpinning the digital broadcasting revolution. Because of its focus on broadcasting, where there is an accepted imbalance between encoder and decoder complexity, this led to significant investment in high-cost, high-complexity encoding ...
MPEG2 - an overview | ScienceDirect Topics
MPEG-2 Video: MPEG-2 video was originally designed for high-quality encoding of interlaced video from standard TV with bit rates on the order of 4–9 Mbits/s. As it evolved, however, MPEG-2 video was expanded to include high-resolution video, such as HDTV, as well as hierarchical or scalable video coding for a range of applications.
MPEG-2 video encoders for broadcast applications
Jan 1, 1996 · For instance, MPEG-2 compression technology allows one satellite transponder with 27 MHz bandwidth to broadcast up to 10 MPEG-2 compressed TV programs, whereas over the same channel only one analog program could be broadcasted. Consequently, such efficiency gains enable return on investments in digital compression technology to be achieved quickly.

Sep 1, 1995 · MPEG-2 video coding standard development An overview of the MPEG-2 video coding stan- dardization process is shown in Fig. 1 where the whole work has proceeded in two phases: competi- tion (divergence) and collaboration (convergence).
MPEG - an overview | ScienceDirect Topics
If an MPEG-2 PES is stored in a file, the file conventionally has the extension m2v; however, a video PES can't contain audio! More commonly, though, MPEG-2 video and audio are multiplexed, then stored or transported, using program streams or transport streams, to be discussed in the chapter MPEG-2 storage and transport, on page 555 .
Transport Stream - an overview | ScienceDirect Topics
An MPEG-2 transport stream (TS) is a part of the MPEG-2 suite of standards that specifies a relatively complex mechanism of multiplexing video and audio for one or more programs into a data stream, typically having short packets, suitable for transmission through error-prone media where relatively powerful forward error-correction (FEC) is ...
Real-time MPEG-2 delivery based on RTP: Implementation issues
Sep 1, 1999 · The processing time required to parse an MPEG-2 slice is proportional to the slice size and varies significantly with the picture type (I, P or B). As an example, in a 2 min test sequence coded using MPEG-2 at 4 Mb/s with 44 macroblocks per slice, we measured the smallest and largest slices. The smallest slice, part of a B frame, was 217 bytes ...
Face and 2-D mesh animation in MPEG-4 - ScienceDirect
Jan 1, 2000 · The representation of synthetic visual objects in MPEG-4 is based on the prior VRML standard [11], [12], [13] using nodes such as Transform, which defines rotation, scale or translation of an object, and IndexedFaceSet describing 3D …

Video transcoding from H.264/AVC to MPEG-2 with reduced …
Sep 1, 2009 · Moreover, MPEG-2 does not allow the same MB partitioning modes neither intraprediction. In the case of MPEG-2, ME is computed for either 16 × 16 or 16 × 8 blocks whereas H.264/AVC allows a wider set of block partitions, such as 16 × 16, 16 × 8, 8 × 16, 8 × 8, 8 × 4, 4 × 8 and 4 × 4.
