Disclosed are various embodiments for associating and synchronizing extrinsic data with video content at particular points of time in the video content. In one embodiment, an application identifies a video content feature currently being presented via a display device. A current time in the video content feature are determined. Performers potentially depicted in the video content feature at the current time are determined. The application then generates a user interface configured to receive a user selection of a particular performer from the performers, where the user selection indicates that the particular performer is depicted in the video content feature at the current time.

Methods, apparatus, systems and articles of manufacture to extend a time range supported by a watermark are disclosed. Example watermark encoding apparatus disclosed herein determine which one of a plurality of timestamp cycles is to be represented by a timestamp of a watermark, the timestamp including a set of timestamp symbols, a first subset of data symbols and a second subset of data symbols. Disclosed example apparatus also modify the first subset of data symbols of the watermark based on a further timestamp symbol not included in the set of timestamp symbols of the timestamp, but not modify the second subset of data symbols based on the further timestamp symbol, the further timestamp symbol to identify the one of the plurality of timestamp cycles to be represented by the timestamp of the watermark. Disclosed example apparatus further embed the watermark in a piece of media.

Systems and methods are presented herein for generating at least one preview of a portion of a content item, wherein the at least one preview is selectable and, when selected, enables a user to change to a playback position of the at least one preview. An input corresponding to a request to generate at least one preview of a portion of a content item is received. At least two key events corresponding to the portion of the content item is identified. In response to identifying the at least two key events, at least one interactive thumbnail corresponding to the at least two key events is generated, wherein the icon corresponds to a preview of the portion of the content item.

In a video system for imaging a target object by using first and second imaging devices, an information processing method is executed by the first imaging device. The information processing method includes: a step for acquiring a first elapsed time indicating the time elapsed after start of recording by the first imaging device; a step for requesting the second imaging device to transmit a second elapsed time indicating the time elapsed after start of recording by the second imaging device, and receiving the second elapsed time; a step for acquiring a required time to receive the second elapsed time after the request is made; and a step for, based on the first elapsed time, the second elapsed time, and the required time, calculating an offset time for synchronizing a first moving image recorded by the first imaging device and a second moving image recorded by the second imaging device.

Provided is a video recording system (10) configured for capturing an object (5) moving along a path (1) including numerous path sections (2, 3, 4). The video recording system (10) includes a first camera (11) operable to capture the object (5) while moving along a first path section (2) of the path (1), a second camera (12) operable to capture the object (5) moving along a second path section (3) of the path (1), and an acquisition unit (31) connected to the first camera (11) and connected to the second camera (12), the acquisition unit (31) being operable to capture a first video stream (51) from the first camera (11) during a first time interval and to capture a second video stream (51′) from the second camera (12) during a second time interval.

The disclosed computer-implemented method includes determining, for multiple different media items, a current time scale at which the media items are encoded for distribution, where at least two of the media items are encoded at different frame rates. The method then includes identifying, for the media items, a unified time scale that provides a constant frame interval for each of the media items. The method also includes changing at least one of the media items from the current time scale to the identified unified time scale to provide a constant frame interval for the changed media item(s). Various other methods, systems, and computer-readable media are also disclosed.
