OSMF 1.6 and higher supports the inclusion of one or more alternative audio tracks with a single HTTP video stream. This practice, referred to as “late-binding audio”, allows content providers to deliver video with any number of alternate language tracks without having to duplicate and repackage the video for each audio track.
In the current technical environment it has become evident that media delivery across devices & platforms is in a state of transition and growth. This growth includes not just the devices and users that are consuming the media, but the technologies and transports that are providing the media across the board. Technologies like HTTP Dynamic Streaming (HDS) are blazing the trail that will ultimately lead the consumer to their content.
Kao tehnologija koje se odnosi na proizvodnju i isporuku digitalnih pokreta medija nastavlja da napreduje, tako da su zahtevi potrošača za sve raznovrsniji i bogatiji mediji iskustveniji.. Video visoke definicije se sada isporučuje na više korisnika, na razlicitim vrstama uređaja, i kroz više kompleksnih mreža nego ikada pre. Za provajdere sadržaja, to naravno znači više raspoloživih mogućnosti za medijsku distribuciju i monetizaciju.
As technologies related to the production and delivery of digital motion media continue to advance, so do consumer demands for an increasingly varied and rich media viewing experience. High-definition video is now being delivered to more users, on a wider variety of devices, and through more complex networks than ever before. For content providers, this of course means more available avenues for media distribution and monetization.
Today Adobe announced the release of the latest sprint for OSMF 1.6, and it includes some exciting new features in terms of how it can handle audio. The biggest new feature is support for multiple audio tracks for HTTP Dynamic Streaming. Known as “late-binding audio”, this methodology allows producers to present multiple audio-only tracks attached to a particular video to the end user. Consider, for example, the need to deliver videos in more than one language. Late-binding audio allows producers to include seperate audio tracks for each language, and then have the viewer choose the appropriate one based on their needs. The benefits to having multiple audio tracks associated with a single video file are savings in encoding time, as well as reduced storage requirements-much more efficient than having to encode and store several different versions of each video. OSMF also supports the ability to switch between audio tracks during playback, which allows even more flexibility in terms of what kind of user experiences are possible.
Currently late-binding audio is available for video-on-demand only, but Adobe promises live/linear support in their next drop.
