Method for signaling haptic information for dash selection process by using initialization segments

A apparatus for haptics processing a dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) application implemented by the at least one processor, the apparatus comprising:

• at least one memory configured to store computer program code;
• and
• the at least one processor which is configured to access the computer program code and operate as instructed by the computer program code, the computer program code including:
• code configured to cause the at least one processor to provide, by the DASH application and to a DASH client, a request for one or more initialization segments from haptic adaptation sets, the request indicating that:
• for a haptics adaptation set of the haptic adaptation sets having a principal initialization segment, only the principal initialization segment is to be downloaded, the principal initialization segment being indicated as having a highest profile and level among other initialization segments of the haptics adaptation, and
• for any other haptics adaptation set of the haptic adaptation sets not having the principal initialization segment, all initialization segments of all representations of that any other haptics adaptation set is to be downloaded,
• receiving code configured to cause the at least one processor to receive, from the DASH client, a media file comprising haptics indicated by an adaptation set of a DASH media presentation description (MPD) manifest, and the one or more initialization segments of representations of a haptics adaptation set, the adaptation set is the haptics adaptation set, the media file indicates a haptics interchange format (HJIF) configuration file to the DASH application;
• parsing code configured to cause the at least one processor to parse, by the DASH client, the one or more initialization segments and any of avatars, perceptions, channels, and band identifiers, of the haptics based on the HJIF configuration file;
• selecting code configured to cause the at least one processor to select a subset of the haptic adaptation sets, including the adaptation set based on parsing any of the avatars, the perceptions, the channels and the band identifiers;
• and
• streaming and rendering code configured to cause the at least one processor to stream and render, in DASH, haptic feedbacks of the media file based on the selected subset of the haptic adaptation sets based on commanding the DASH client to stream from the selected haptics adaptation sets.

A non-transitory computer readable medium storing a program causing a computer to execute a process, by a dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) application implemented by the computer, the process comprising:

• providing, by the DASH application and to a DASH client, a request for one or more initialization segments from haptic adaptation sets, the request indicating that:
• for a haptics adaptation set of the haptic adaptation sets having a principal initialization segment, only the principal initialization segment is to be downloaded, the principal initialization segment being indicated as having a highest profile and level among other initialization segments of the haptics adaptation, and
• for any other haptics adaptation set of the haptic adaptation sets not having the principal initialization segment, all initialization segments of all representations of that any other haptics adaptation set is to be downloaded,
• receiving, from the DASH client, a media file comprising haptics indicated by an adaptation set of a DASH media presentation description (MPD) manifest, and the one or more initialization segments of representations of a haptics adaptation set, the adaptation set is the haptics adaptation set, the media file indicates a haptics interchange format (HJIF) configuration file to the DASH application;
• parsing, by the DASH client, the one or more initialization segments and any of avatars, perceptions, channels, and band identifiers, of the haptics based on the HJIF configuration file;
• selecting a subset of the haptic adaptation sets, including the adaptation set based on parsing any of the avatars, the perceptions, the channels and the band identifiers;
• and
• streaming and rendering, in DASH, haptic feedbacks of the media file based on the selected subset of the haptic adaptation sets based on commanding the DASH client to stream from the selected haptics adaptation sets.
