This is less of a problem for the decoding in the client because the algorithms tend toward techniques that are very easy to decode. On the downside, newer codecs or upgrades to existing models will require greater CPU power to leverage the improved algorithms. The longer a codec has been around, the more tricks have been developed to exploit the encoder. Longevity of the codec also comes into play. In general, the more modern the codec design, the better the compression ratio compared with the original source material.

So profiles help to keep the software implementation under control as well.

#WHY DO I NEED A VC1 CODEC PORTABLE#

The portable device would probably not have the memory or compute power to cope with it anyway. A complete MPEG-4 encoder would be of no use in a portable device because you don’t need the more esoteric features. A maximally implemented decoder that supports everything MPEG-4 defines would be a very unwieldy and large piece of software that would be inappropriate for a lot of applications. Having defined a profile, the encoder must honor that and not create a coded representation that is any more complex than the profile allows.ĭecoders are implemented up to a certain profile level and support content from the lowest to the highest they are capable of and everything in between. Simple decoders check the profile of the incoming video and either attempt to decode it or display a message explaining why they will not.

New opportunities for more radical improvement are presented when rolling MPEG-2 decoders out to “greenfield” situations where there is no prior deployment, although these are also candidates for H.264 and VC-1 codec implementation.īy defining the characteristics of a compliant decoder, the encoder manufacturers are free to innovate in any way they like, so as to generate the most efficiently coded representation of the original video source material.Ĭertain features might be allowed or disallowed by defining profiles. There is still some room for improvements to the efficiency, but this is bounded by the need to remain 100% compliant with all the decoders that have been deployed. Bit rates as low as 3.5 Mbps are routinely used for broadcast. MPEG-2 has improved in efficiency by a factor of about 2:1 since the original coders were introduced.
