Assistance information related to a tier framework may describe signaling for extractable and decodable sub-sequences based on pictures interdependencies. This may allow a video application to efficiently select pictures when performing a given trick mode.

Among other things, videos and commercials are downloaded to a mobile device for storage on the mobile device and later playout on the mobile device. The downloading includes downloading of metadata associated with the commercials and based on which the mobile device can select commercials for insertion into videos being played back to the user of the mobile device. The commercials to be downloaded are selected based on one or a combination of any two or more of the location of the user, the type of mobile device, and personally-identifiable information about a user of the mobile device.

An example method involves: accessing a first list that includes ordered clip identifiers C.sub.1 . . . C.sub.n separated at least into a first block of clip identifiers C.sub.1 . . . C.sub.j and a second block of clip identifiers C.sub.j+1 . . . C.sub.k; accessing a second list that includes ordered player identifiers P.sub.1 . . . P.sub.x; assigning to each clip identifier C.sub.1 . . . C.sub.j in order a respective one of the player identifiers P.sub.1 . . . P.sub.x selected in an ordered and looping fashion starting with one of the player identifiers P.sub.1 . . . P.sub.x; assigning to each clip identifier C.sub.j+1 . . . C.sub.k in order a respective one of the player identifiers P.sub.1 . . . P.sub.x selected in an ordered and looping fashion starting with the player identifier P.sub.1; and traversing the clip identifiers C.sub.1 . . . C.sub.k, and for each traversed clip identifier, causing a player identified by the one of the player identifiers P.sub.1 . . . P.sub.x assigned to the traversed clip identifier to load a clip identified by the traversed clip identifier.

A playback method according to one aspect of the present disclosure is performed by a playback device connected to a display device. The playback method includes obtaining a type of the display device; selecting each of a version of High-Definition Multimedia Interface (HDMI) and a version of High-bandwidth Digital Content Protection (HDCP), according to the obtained type of the display device; obtaining a video signal of content recorded on a recording medium; decoding the obtained video signal; encrypting the decoded video signal using the selected version of HDCP; and outputting the encrypted video signal to the display device using the selected version of HDMI.

Various mechanisms presented in this disclosure provide for dynamically adjusting the exhibition of subtitles. In one example, check-points are introduced into the subtitle file format that, once achieved by a multimedia player, provoke the rescheduling of the moment in which the texts contained in the subtitle file will be exhibited.

There are several types of plenoptic devices and camera arrays available on the market, and all these light field acquisition devices have their proprietary file format. However, there is no standard supporting the acquisition and transmission of multi-dimensional information. It is interesting to obtain information related to a correspondence between pixels of a sensor of said optical acquisition system and an object space of said optical acquisition system. Indeed, knowing which portion of the object space of an optical acquisition system a pixel belonging to the sensor of said optical acquisition system is sensing enables the improvement of signal processing operations. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera along with a compact format for storing such information is thus introduce.

Methods, systems, and apparatus, including computer program products, for presenting subtitles. A video is played on a display of a device. A display mode for the video is detected. A subtitle is presented in one of a plurality of presentation formats based on the detected display mode.

The present invention relates to an input/output system for an ultra high definition image, and more specifically, to an input/output system for an ultra high definition image that may receive an ultra high definition image signal from an external device, process the signal in real time, and output the processed ultra high definition image signal. For this purpose, a system configured to convert data having various resolutions into UHD data of the present invention includes a content input/output device configured to provide data received from a data providing device to an editing device and provide the data received from the editing device to a content reproducing device, and an editing device configured to convert the data received from the content input/output device into UHD data and provide the result to the content input/output device.

A video processing system includes: an object movement information acquiring means for detecting a moving object moving in a plurality of segment regions from video data obtained by shooting a monitoring target area, and acquiring movement segment region information as object movement information, the movement segment region information representing segment regions where the detected moving object has moved; an object movement information and video data storing means for storing the object movement information in association with the video data corresponding to the object movement information; a retrieval condition inputting means for inputting a sequence of the segment regions as a retrieval condition; and a video data retrieving means for retrieving the object movement information in accordance with the retrieval condition and outputting video data stored in association with the retrieved object movement information, the object movement information being stored by the object movement information and video data storing means.
