          Platform: Unspecified

            Status: NEW
          Severity: Enhancement
          Priority: P2

        ReportedBy: cyril.concolato at telecom-paristech.fr


Apple iOS applications support the playback of MPEG-2 transport streams containing ID3 PES Streams for synchronized timed-metadata [1]. On iOS, it is thus possible to write native applications that use this timed metadata, such as in [2]. The HTML 5 specification provides a way to expose timed metadata to Web applications in the form of an HTML 5 TextTrack of kind 'metadata' [3]. It would be good to expose this ID3 metadata using the TexTrack to be able to reproduce the behavior of the native application in Web apps. 

Note that some work towards standardizing how to expose metadata tracks is being carried in a W3C community group [4].
