    History Of ASP MPEG-4

    What is MPEG-4 video codec?

    MPEG-4 is for the latest video/audio compression standardized by the MPEG group and specifically designed for low bandwidth video/audio coding (bitrate less than 1.5 Mbps). MPEG-4 was developed to provide DVD (MPEG-2) video quality at a lower bit rate and smaller history.

    Originally designed for commercial streaming applications such as video conferencing, MPEG-4 did not attract much public attention until Microsoft’s program for a new compression format (Windows wmv Media Video) with MPEG-4 Part 2, ASP was leaked among its 21 profiles. Code Ones was released as DivX 😉 3.11 Alpha.

    Project Mayo

    The availability of all source code from Microsoft generated enough interest among vendors to start a Mayonnaise Also project called OpenDivX. OpenDivX development would end when the original developers decided to create a commercial encoder and also founded DivXNetworks. Their DivX codec has been a major driver of consumer interest in MPEG-4 since the beginning. Other developers who have made the decision continue to develop open source and experiment by creating XviD. The 2 most important codecs are definitely being seen by more mature companies, and a number of MPEG-4 ASP encoders are being sold.


    Since there was no official MPEG-4 container prior to the development of MPEG-4 (H avc.264), early MPEG-4 enthusiasts used Microsoft’s AVI container to store MPEG-4 and MP3 video. appear. However, with the development of individual containers and consumer softwareThere are probably much better containers like Vision (official MPEG-4 mp4 container), MKV (Matroska container) or even MPG (MPEG-2 program stream) out there. the best alternatives, each supporting advanced video development capabilities and portability across operating systems. AVI is a special format from Microsoft and Windows.

    Hardware Support

    With the release of the KISS DP-450 in 2002, MPEG-4 ASP decoding became available for the first time in a standalone DVD player. I had to use personal AVI recordings, and there were usually problems with the number due to the peculiarities of MPEG-4 ASP. Although the market will grow soon, there are official certification programs from a large number of codec vendors, including DivX, XviD and Nero Digital. Apart from AVI support, the new players also promote the MP4 container. DivX has created an extension for AVI, a special container that allows you to use it behind simple menus like a very simple DVD.

    Is MPEG-4 Same as MP4?

    Are MP4 and MPEG4 the same thing? The short answer is definitely “No”. MP4 is a video format that can store various media files, but is also usually compressed using the MPEG4 codec, but not always. While MPEG4 itself can be applied to many types of file formats, including MP4, MOV, AVI, MKV, OGG, and MXF.

    MPEG-4 ASP shares some similarities with MPEG-2 image encoding, but also has some important differences. As part of the current MPEG-4 family, itslightly more powerful but not as efficient as MPEG-4 AVC which was developed later. This means smaller file sizes and comparable quality to MPEG-2 files.

    Despite ASP profile support, related encoding is not available in all encoders. Since MPEG-4 did not exist for DVD enthusiasts in the early days of MPEG-4 encoding, and HTPCs were also initially rare, almost everything encoded in the early years of DivX development was progressive to adapt to individual computer screens. . Since most of the generators are from the movie, that is, they are also advanced, this was not actually a malfunction. However, if you’re encoding features on an analog TV, such as via a standalone DVD player, you’ll probably want to make sure you’re using a codec that’s appropriate for the encoding that’s connected. Fortunately, this has become a fairly standard feature for encoders and decoders.

    Another common MPEG-4 profile, the Simple Profile or SP, can be described as intended for low power processors. Therefore, no B-frames are allowed. B-framesBidirectional prediction encoded frames require the decoding of two training resource frames compared to one reference frame required for P-frames. Because ASP does not have this hardware mental limitation, it supports loading B-frames.

    Quarter pixel motion compensation allows calculations used for functional ROM detection (for prediction purposes) to be performed with greater accuracy than MPEG-2. While you can’t store less than a whole pixel, it doesn’t guarantee that your video’s motion will span every 1 pixel step. Increasing the accuracy to a significant 1/4 pixel (up from MPEG-2’s half-pixel accuracy) improves the idea, which sometimes means a better peak at a comparable bitrate. Older standalone DVD players that support MPEG-4 ASP will not play Qpel encoded files, but newer models should not have this problem.


    This has happened before, when the MPEG-4 part (AVC/H 10.264) was finalized and subsequently adopted for the deployment of various technologies, from mobile devices and listening From music to digital television and the Internet. ASP Blu-ray online video. Since AVC decoders are generally unable to decode ASP video, this means that standalone internet poker DVD players must have more hardware, or at least more complexity, to support both. With the exceptional compression and image quality of AVC, there is no reason to use MPEG-4 ASP for too long.

    Is MPEG-4 better than h264?

    H.264 is a new video compression standard that offers more advanced compression methods than basic MPEG-4 compression. This is about 1.5-2 times more efficient when it comes to MPEG-4 encoding. This high level of compression allows information to be stored on a single disk.

    MPEG-4 ASP, or Active Simple Profile, was the video compression standard in MPEG-4 traceable part 2. The most common implementations of ASP MPEG-4 are probably DivX and XviD, although many other codecs are also available for purchase. . Since this is a standard codec and not the best codec, any MPEG-4 ASP certified decoder can play standards-encoded video with any program. In other words, DivX decoders should have no problem playing XviD video.
