MPEG 4 AVC for advanced video coding.Its a joint standard promulgated by the ITU T Video Coding Experts Group VCEG and the ISOIEC Moving Picture Experts Group MPEG.H.AAC advanced audio coding, which is designated MPEG 4 Part 3.Both H.AAC are technically MPEG 4 codecsthough its more accurate to call them by their specific namesand compatible bitstreams should conform to the requirements of Part 1.MPEG 4 spec.According to Part 1.MPEG 4 files containing both audio and video, including those with H.AAC, should use the.Different vendors have adopted a range of extensions that are recognized by their proprietary players, such as Apple with.Fair.Play Digital Rights Management and.Phone ringtones.Mobile phones use the.I dont discuss producing for mobile phones in this article.Like MPEG 2, H.GOP is comprised of I, B, and P frames, with I frames like the DCT based compression used in DV and B and P frames referencing redundancies in other frames to increase compression.Ill cover much more on this later in this article.Like most video coding standards, H.Overview of the H.AVC Video Coding Standard published in IEEE Transactions on Circuits and Systems for Video Technology ITCSVT.Basically, this means that theres no standardized H.In fact, H.This is one of the key reasons that H.Will there be royalties If you stream H.December 3.As yet, however, its undefined and uncertain.Heres an overview of whats known about royalties to date.Briefly, H.MPEG Licensing Suthoring, or MPEG LA for short.According to the Summary of AVCH.License TermsPDF, 3.K you can download from the MPEG LA site, there are three classes of video producers subject to a potential royalty obligation.If youre in the first two classes, and are either distributing via pay per view or subscription, you may already owe MPEG LA royalties.The third group, which is clearly the largest, is for free Internet broadcast.Here, there will be no royalties until December 3.AVCH.License Agreement.After that, the royalty shall be no more than the economic equivalent of royalties payable during the same time for free television.According to their website, MPEG LA must disclose licensing terms at least one year before they become due, or no later than December 3.Until then, were unfortunately in the dark as to which uses of H.For more information on H.The Futures So Bright H.Year in Review, at Streaming.Media.H. 2.Flash Player.As I mentioned, Adobe added H.Adobe Flash Player 9 Update 3 back in 2.The apparent goal was to support the widest possible variation of files containing H.Flash Player should play.H.Flash Player 9 see Table 1.Table 1.

V format is not offered in your encoding tool, the best alternative is to produce an MPEG 4 compatible streaming media file using the.With this as background, Ill describe the most common H.H.Though H. 2. 64 codecs come from different vendors, they use the same general encoding techniques and typically present similar encoding options.Here I review the most common H.Understanding profiles and levels.According to the aforementioned article, Overview of the H.AVC Video Coding Standard, a profile defines a set of coding tools or algorithms that can be used in generating a conforming bitstream, whereas a level places constraints on certain key parameters of the bitstream.In other words, a profile defines specific encoding techniques that you can or cant utilize when encoding the files such as B frames, while the level defines details such as the maximum resolutions and data rates.Take a look at Figure 1, which is a filtered screen capture of a features table from Wikipedias description of H.On top are H.Baseline, Main, High, and High 1.Flash Player supports.On the left are the different encoding techniques available, with the table detailing those supported by the respective profiles.Figure 1.Encoding techniques enabled by profile source WikipediaAs you would guess, the higher level profiles use more advanced encoding algorithms and produce better quality see Figure 2.To produce this comparison, I encoded the same source file to the same encoding parameters.The file on the left uses the Main Profile the files on the right uses the Baseline.A quick check of the chart in Figure 1 reveals that the Main Profile enables B slices also called B frames and the higher quality CABAC encoding, which I define later in this article.As you can see, these do help the Main Profile deliver higher quality video than the Baseline.Figure 2.
