RE: [HOME_NETWORK_TF] Video tag support of MPEG2-TS

Hello Matt,

The scenario is if I am watching a video on a browser that supports MPEG2-TS. The architecture as to the transmission are various.

A TV with DVB-T tuner support could have an application that controls the MPEG2-TS. This is today well covered by HbbTV. As HTML5 matures and more applications are using the new markup (ex. YouTube) ideally one wants to converge with the same video presentation mechanisms. To achieve a converged solution that puts requirements on HTML5 and I tried to capture the essence of what those requirements are.

Another scenario is a DLNA home network. The support of MPEG2-TS is a requirement in DLNA (depending on profile they are mandatory and optional). If a DMP device with a browser shall support MPEG2-TS then these requirements have to be fulfilled if you want to have a good user experience.

While HTML5 video tag fulfills most requirements like reading of available tracks for audio, video and subtitles the supported the support of a live stream where the available tracks change over time are not covered. The available language may change from one program to the next.

Best regards,

Hello Jan,

Could you describe a simple scenario that demonstrates the issue?
