摘要:
A receiving method of receiving a first data unit in which data making up an encoded stream is stored and the first data unit stores a plurality of second data units. The receiving method includes: receiving the first data unit, first time information indicating a presentation time of the first data unit, second time information indicating, together with the first time information, a presentation time or a decoding time of each of the plurality of second data units, and identification information; calculating the presentation time or the decoding time of each of the plurality of second data units using the first time information and the second time information; and correcting the presentation time or the decoding time of each of the plurality of second data units based on the identification information.

By way of example, a computing system may include an enclave or other similar secured memory location or process. When the system receives new content or data, it may classify the content as potentially harmful and initially render and display the content in the enclave. The user may then select portions of the content to enable or disable in a final version. The content may also be converted to a known “safe” equivalent format that always renders in the enclave. Enclave-rendered content may be signed by the enclave so that they can be considered “trusted” so long as the certificate remains valid and the content is correctly signed.

Provided are a content security method and an electronic apparatus for providing a content security function. The content security method according to an embodiment of the present invention includes: generating a security key used to decrypt security content; generating a security message based on the security key, content transmitter identification information, and content receiver identification information; generating the security content by encrypting content; and transmitting the security content and the security message to an external electronic apparatus.

Efficient techniques are provided for delivering video content appropriate for viewership on various display sizes and for zooming video content at a receiver device, upon reception of the video content. Information for zooming video content is embedded prior to delivering the video content. The information includes a position of a bounding box in a plurality of video frames of the video content. The position can be represented by a polynomial function. Temporal smoothing of the position and compression of the information can be applied. Methods (900, 1000), apparatuses (100,1100), computer-readable storage mediums and non-transitory computer-readable program products are provided for delivering video content and for zooming video content.
摘要:
A method and apparatus for creating media content. The method comprises recording a video; while the video is being recorded, automatically analysing the content of the video; and creating media content by editing the video, assisted by the results of the content-analysis. A user may not need to select in advance (that is, before the video is recorded) the type or format of media content to be created.
摘要:
Embodiments of techniques and systems for content protection and detection of protected media content are described. Visual tracking patterns may be displayed during rendering of protected media content that would be visible to a camcorder during recording. The visual tracking pattern may be placed in a background area or other less-active portion of the video in order to reduce perceptibility by a viewer. Audio tracking patterns may be inserted during rendering outside of the range of normal human hearing for reduced viewer perceptibility. The tracking patterns may encode media tracking codes that are included in to-be-rendered media during provision from a media server. Other embodiments may be described and claimed.

A method for acquiring and storing data relating to video streams selectable on a video processing apparatus adapted to select a video stream reproducible on an associated reproduction device includes: identifying the source of the video stream by identification data, the video stream having a coding and transport configuration adapted to produce a three-dimensional display; verifying if, for the identified video stream, any data relating to the coding and transport configuration of the video stream are stored by the video processing apparatus in storage of the video processing apparatus including associations between video stream identification data and video stream coding and transport configurations; when affirmative, acquiring from the storage the coding and transport configuration associated with the video stream identified by the identification data, and using the data for a following selection of the video stream in order to reproduce the selected video stream on an associated video reproduction device.
摘要:
Provided are a method and apparatus for encoding/decoding video data. The video data decoding method includes decoding a first video stream to generate 2D video data for two-dimensionally displaying video content and decoding a second video stream to generate 3D video data for three-dimensionally displaying at least one part of the display section of the video content.
摘要:
The present application concerns the field of digital TV, particularly a method to trace the origin of a (illegally) distributed video material. It is proposed a method for fingerprinting a data object A having a nominal stream format F, to provide a fingerprinted data object B, comprising the pre-fingerprinting and forensic luring process, wherein the said pre-fingerprinting process comprising the steps of: - Determining elements, having each respectively an original value and a position within the said original data object (A), - Replacing each original value by an alternate value to create a modified data object C, - Extending the said modified data object C with one supplementary object Ss to provide a fingerprinting-ready data object D, said supplementary object Ss comprising, for each element, a subset object comprising the positions to locate the elements, a first and a second replacement value;
the said forensic luring process comprising the steps of: - Extracting the supplementary object (Ss) from the fingerprinting-ready data object (D), and identifying the said modified elements within the said fingerprinting-ready data object D as well as the positions with the aid of the said supplementary objects (Ss), - Obtaining an identifier to be associated with the fingerprinted data object, - Modifying the alternate values at positions in the elements, and for each element selecting one of the replacement values based on all or part of the identifier to create the fingerprinted data object.
