Further enhancements have been introduced in Rel and recently started Rel In parallel to LTE evolution, both releases initialized, the first set of study and work items towards 5G. While Rel focused solely on 5G study items, the normative work for the first phase of 5G system specification has started just recently within Rel targeting freeze date of September
Compression is further improved by choosing filter types adaptively on a line-by-line basis. This improvement, and a heuristic method of implementing it commonly used by PNG-writing software, were created by Lee Daniel Crockerwho tested the methods on many images during the creation of the format;  the choice of filter is a component of file size optimization, as discussed below.
If interlacing is used, each stage of the interlacing is filtered separately, meaning that the image can be progressively rendered as each stage is received; however, interlacing generally makes compression less effective. PNG offers an optional 2-dimensional, 7-pass interlacing scheme—the Adam7 algorithm.
This is more sophisticated than GIF's 1-dimensional, 4-pass scheme, and allows a clearer low-resolution image to be visible earlier in the transfer, particularly if interpolation algorithms such as bicubic interpolation are used.
MNG shares PNG's basic structure and chunks, but it is significantly more complex and has a different file signature, which automatically renders it incompatible with standard PNG decoders.
However, neither of these formats is currently widely supported. APNG is supported in Firefox 3. Whereas GIF is limited to 8-bit indexed colorPNG gives a much wider range of color depths, including bit 8 bits per channel and bit 16 bits per channel truecolorallowing for greater color precision, smoother fades, etc.
GIF intrinsically supports animated images. PNG supports animation only via unofficial extensions see the section on animationabove. PNG images are less widely supported by older browsers. JPEG Joint Photographic Experts Group format can produce a smaller file than PNG for photographic and photo-like images, since JPEG uses a lossy encoding method specifically designed for photographic image data, which is typically dominated by soft, low-contrast transitions, and an amount of noise or similar irregular structures.
In comparison, when storing images that contain text, line art, or graphics — images with sharp transitions and large areas of solid color — the PNG format can compress image data more than JPEG can.
Such artifacts depend on the settings used in the JPG compression; they can be quite noticeable when a low-quality [high-compression] setting is used. Where an image contains both sharp transitions and photographic parts, a choice must be made between the two effects.
JPEG does not support transparency. JPEG's lossy compression also suffers from generation losswhere repeatedly decoding and re-encoding an image to save it again causes a loss of information each time, degrading the image.
This does not happen with repeated viewing or copying, but only if the file is edited and saved over again. Because PNG is lossless, it is suitable for storing images to be edited.
While PNG is reasonably efficient when compressing photographic images, there are lossless compression formats designed specifically for photographic images, lossless WebP and Adobe DNG digital negative for example. However these formats are either not widely supported, or are proprietary. An image can be stored losslessly and converted to JPEG format only for distribution, so that there is no generation loss.
The PNG specification does not include a standard for embedding Exif image data from sources such as digital cameras. Instead, PNG has various dedicated ancillary chunks for storing the metadata that other file formats such as JPEG would typically store in Exif format.
JPEG was commonly used when exporting images containing gradients for web pages, because of GIF's limited color depth.5G System Phase-1 – a stage 2 normative specification for 5G phase 1 system with the following key features: network slicing; access and mobility management; QoS framework; policy framework; network sharing; access of untrusted non-3GPP; interworking, migration, roaming with EPS, etc.
