MPEG-2 Reception Basics and A Brief History In the American Market HISTORY & TECHNICAL BACKGROUND: Asia and the Pacific Rim were the first places in which MPEG-2 free-to-air reception was used on a large scale. The difference between those markets and America was that prior to the mid 90s, it took literally very huge antennas to get even a few dozen channels...making TV reception of many channels an impossible dream. MPEG-2 technology was a breakthrough that allowed great reductions in per-channel transmission costs. Mass consumers in those regions never had the chance to spend lots of money on more costly analog equipment. Their first exposure to satellite TV was more often than not in a digital format. No 15 to 20 year learning curve of various stages of analog receivers prior to going to digital, like we did here. So the Asia-Pacific market was a test bed on how to get it right, with costs coming down due to companies from the Far East trying to compete for the huge mainland Chinese market. Then Europe....now America. Hyundai was the first receiver brought into the U.S., with its early versions of the HSS-100 series of receivers. Wholesale cost was around $700, it had a memory limited to 99 bouquets, or groups of channels, and the graphics only worked in the PAL video format. Viewing on our NTSC format required a direct connection to a VCR or monitor and some programming tricks to "make" an NTSC picture. We have come a long ways in the last three years, with many significant improvements in design of receivers, and great increases in memory capacity. MPEG-2 is a worldwide satellite transmission standard for digital broadcasting. It is the wave of the future, because of the simple economics that can allow 8 or even 10 video signals to occupy the same space as one channel of analog transmission. Just as some analog signals can be scrambled for subscription use, digital channels can be transmitted either scrambled or in-the-clear. In-The-Clear is known in the digital TV world as FTA or Free-To-Air. Since it is a worldwide standard, there are more MPEG-2/DVB (digital video broadcasting) channels available in places such as Europe, the Middle East, and Asia, than presently found in the American market. National public broadcasters in other parts of the world have adopted MPEG-2 as a cost-effective way to distribute their signals on limited budgets. Spread of free MPEG-2 signals into North America has been previously hampered by the dominance of the Digicipher 2 video standard made by the former General Instrument (now Motorola Broadband) group. Receivers such as 4DTV and other versions of the Digicipher 2 actually have the letters MPEG-2 stamped on them, but are not compatible with the rest of the world. The difference comes in the way that signals are layered together, especially in the encryption process. It has given the Digicipher 2 a protected monopoly in America. Scientific-Atlanta's PowerVu system is more closely related to MPEG-2, and it has a lion's share of digital channels in the rest of the world. It helps that the worldwide PanAmSat satellite system works closely with Scientific-Atlanta in promoting this digital alternative. What is unique is that when signals are NOT addressably encoded, the PowerVu system can be viewed in-the-clear (or Free-to-Air) on most consumer MPEG-2 digital receivers. Several DBS systems in North America use the MPEG-2 platform, and when they choose NOT to encode channels, signals are also available in the same manner. These include Echostar's DISH Network, Canada's Bell ExpressVu, Mexico's SKY MEXICO, and the former Sky Vista and AlphaStar...once on Telstar 5 but now out of business. |

It also specifies the format of movies and other programs that are distributed on DVD and similar disks. As such, TV stations, TV receivers, DVD players, and other equipment are often designed to this standard. MPEG-2 was the second of several standards developed by the Moving Pictures Expert Group (MPEG) and is an international standard (ISO/IEC 13818). Parts 1 and 2 of MPEG-2 were developed in a joint collaborative team with ITU-T, and they have a respective catalog number in the ITU-T Recommendation Series. MPEG-4 provides a series of technologies for developers, for various service-providers and for end users. MPEG-4 enables different developers to create objects possessing better abilities of adaptability and flexibility to improve the quality of such services and technologies as digital television, animation graphics, World Wide Web and their extensions. This standard enables developers to control their content better and to fight more effectively against copyright violations. Various network providers can use MPEG-4 for data transparency. With the help of standard procedures such data can be interpreted and transformed into various signals compatible with any available network. The MPEG-4 format provides the end users with a wide range of interaction with various animated objects. Standardized Digital Rights Management signaling, otherwise known in the MPEG community as Intellectual Property Management and Protection (IPMP). The MPEG-4 format can perform various functions, among which might be the following: Multiplexes and synchronizes data, associated with media objects, in such a way that they could be transported further via network channels. Interaction with the audio-visual scene, which is formed on the side of the receiver. DivX is a brand name of products created by DivX, Inc. (formerly DivXNetworks, Inc.), including the DivX Codec which has become popular due to its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality. The DivX codec uses lossy MPEG-4 Part 2 compression, also known as MPEG-4 ASP, where quality is balanced against file size for utility. It is one of several codecs commonly associated with "ripping", where audio and video multimedia are transferred to a hard disk and transcoded. Many newer "DivX Certified" DVD players are able to play DivX encoded movies, although the Qpel and global motion compensation features are often omitted to reduce processing requirements. They are also excluded from the base DivX encoding profiles for compatibility reasons. |

The picture data is transferred at a rate of about 30 frames per second, for a beautiful, smooth motion image. It will show up on your SD Memory Card as ".MOD" or ".MOI". MPEG4 video is suitable for use in a compatible PC, viewing on a TV, posting on Web pages or attaching to e-mail. It is inferior to MPEG2 in smoothness because the number of the frames transferred in MPEG4 is less than that in MPEG2. However, MPEG4 has a higher transfer rate, and a much smaller file size, than MPEG2. It will show up on your SD Memory Card as ".ASF", which stands for Advance Systems Format files. MPEG-2 The MPEG-2 project focused on extending the compression technique of MPEG-1 to cover larger pictures and higher quality at the expense of a lower compression ratio and therefore also higher bandwidth usage. MPEG-2, ISO/IEC 13818, also provides more advanced techniques to enhance the video quality at the same bit-rate. The expense is the need for far more complex equipment. Therefore these features are not suitable for use in real-time surveillance applications. As a note, DVD movies are compressed using the techniques of MPEG-2. MPEG-4 Also the third generation of MPEG is based upon the same technique. Once again, the new project focused on new application usages. The most important new features of MPEG-4, ISO/IEC 14496, concerning video compression are the support of even lower bandwidth consuming applications, e.g. mobile units, and on the other hand applications with extremely high quality and almost unlimited bandwidth. The making of studio movies is one such an example. Most of the differences between MPEG-2 and MPEG-4 are features not related to video coding and therefore not related to surveillance applications MPEG -- Motion Picture Experts Group.

Silver Member Username: The_codersPost Number: 906 Registered: Jan-08 | MPEG-4 is a collection of methods defining compression of audio and visual (AV) digital data. It was introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) under the formal standard ISO/IEC 14496. Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications. MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally-specified Digital Rights Management and various types of interactivity. AAC (Advanced Audio Codec) was standardized as an adjunct to MPEG-2 (as Part 7) before MPEG-4 was issued. MPEG-4 is still a developing standard and is divided into a number of parts. The companies promoting MPEG-4 compatibility do not always clearly state which "part" level compatibility. The key parts to be aware of are MPEG-4 part 2 (MPEG-4 SP/ASP, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by Quicktime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264, used by the x264 codec, by Nero Digital AVC, by Quicktime 7, and by next-gen DVD formats like HD DVD and Blu-ray Disc). Most of the features included in MPEG-4 are left to individual developers to decide whether to implement them. This means that there are probably no complete implementations of the entire MPEG-4 set of standards. To deal with this, the standard includes the concept of "profiles" and "levels", allowing a specific set of capabilities to be defined in a manner appropriate for a subset of applications. Initially, MPEG-4 was aimed primarily at low bit-rate video communications; however, its scope was later expanded to be much more of a multimedia coding standard. MPEG-4 is efficient across a variety of bit-rates ranging from a few kilobits per second to tens of megabits per second. MPEG-4 provides the following functionalities: * Improved coding efficiency * Ability to encode mixed media data (video, audio, speech) * Error resilience to enable robust transmission * Ability to interact with the audio-visual scene generated at the receiver |
