Abstract

As the newly created standard for interactive television, HbbTV (for Hybrid broadband broadcast TV), is getting traction, the problem of recording TV services takes on new dimensions with interactive and hybrid services. This paper explores the different issues raised by the recording and on-demand playback of broadcast HbbTV services containing interactive applications. Adaptive streaming tools provide part of the solution. Guidelines to application developers and small extensions to HbbTV are also proposed. We describe possible implementations based on MPEG-2 TS and discuss an alternative based on ISOBMFF.
