Problems solved by technology

[0004] Another such problem is that it may be difficult to randomly access points in a media transport stream with both media and haptic signals
In other words, when a user starts playback of a portion of a media transport stream at an arbitrary point without access to any data that may have occurred prior to that point in the media transport stream, it is difficult to synchronize the haptic signal with the media signal

Embodiment Construction

[0020] Embodiments are described herein in the context of methods, systems, and apparatus for communicating media transport streams that include haptic information. Those of ordinary skill in the art will appreciate that the following description is illustrative only and is not intended to be limiting in any way. Other embodiments will readily occur to such skilled persons having the benefit of this disclosure. Reference will now be made in detail to implementations of example embodiments as illustrated in the accompanying drawings. Throughout the drawings and the following description, the same reference designators will be used to refer to the same or similar items.

[0021] In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. Of course, it will be appreciated that in the development of any such actual implementation, many implementation-specific decisions must be made in order to achieve the developer...

Abstract

Haptic information in a series of frames of a media file is identified and time stamps corresponding thereto are determined in accordance with information embedded in a tag either preceding or appending the media file. The haptic effect information is automatically synchronized to the media file based on the information in one or more frames of the tag, whereby an actuator outputs the defined haptic effects in the tag in a manner synchronized with corresponding audio and / or video content of the media file.

Description

technical field [0001] The subject matter described herein relates to synchronizing haptic effects with audio and / or video content data in media files. Background technique [0002] To improve the interface between a user and a machine, it has become more common in recent years to incorporate haptic effects into the interface along with audio and / or video media. Haptic effects such as vibrations can be felt by the user, and can often be associated with an event trigger, such as pressing a button on the device or playing a ringing tone announcing an incoming call or receiving a text message on a mobile phone, etc. Often, media playback can complement vibration. However, conventional methods of implementing haptic effects have some problems when playing haptic signals and media signals over a period of time. [0003] One such problem is the need to enable synchronized playback between haptic signals and other media signals, such as video and / or audio signals. Typically, the...
