An enterprise based workflow server based system to detect and classify images as potentially of pornographic nature. The system is based on two independent stages. The first stage is an automatic stage which eliminates most images that are positively non pornographic, including an image analysis engine with a plurality of sub engines, each dedicated to different attributes of an image. The second stage describes an additional embodiment of a manual review stage. An alternative embodiment describes a similar server solution to detect images suspected as copyrighted material. The images can be individually classified, or analyzed as a cluster or a collection of images such as an album or motion-picture segment, sampled into key still frames. The system optimizes time saving by elimination of images, and assures accuracy by generating a workflow reviewing solution which can involve a human decision-making stage.

A data storage, multiplexing, and distribution method is provided for use in a digital data distribution system. The system provides simultaneous transmission of a plurality of uniquely identified, independent data streams within an assigned channel bandwidth of local, metropolitan and wide area distribution media. The independent data streams can include presentations specifically requested by the receiving user. Upon request from some number of users from their premises, the system assembles a combination of optional image elements such as motion and still frame video, background and descriptive audio, text and graphical overlays into presentation data streams appropriate to the user requests. Individual data streams are multiplexed within a higher bandwidth data stream for simultaneous delivery within the bandwidth assigned for this data transmission. The techniques unique to the system, in regard to storage, timing and synchronization, can be implemented using techniques described within the MPEG profile.

A method for processing video includes providing a framegrabbing plugin that extracts still frames from a video stream and is integrated into an application that hosts plugins and providing a user interface allowing a user to select still frames to extract from the video.

A system and method for creating still images by utilizing a video camera comprises a cradle device that transports the video camera across a target object during a scanning procedure that captures and stores video data. During the scanning procedure, a motion detector captures and provides scan motion data to a scanning manager from the video camera. The scanning manager may then responsively utilize the scan motion data to accurately extract still frames corresponding to the target object from the captured video data at pre-determined time intervals. A stitching software program may then access and combine the still frames generated by the scanning manager to thereby create composite still images.

A client device sends the following data to the servers: still frames from captured video and in some embodiments other data such as GPS coordinates, compass reading, and accelerometer data. The servers break down each frame into feature points and match those feature points to existing point cloud data to determine client device's point of view (POV). The servers send the resulting information back to the client device, which uses the POV information to render augmentation content on a video stream. Information sent by client devices to the server can be used to augment the feature-point cloud.

Method, system and computer program product are provided for adaptively encoding in hardware, software or a combination thereof a series of still or partially still pictures using motion video encoding. A pre-encode statistics measurement unit is employed to derive statistics on each frame of the sequence of video frames to be encoded. The statistics are determinative of whether the frame comprises a still frame. If so, at least one controllable parameter to be used to encode the still frame is modified, and an encoding engine employs the at least one controllable parameter to encode the still frame so that pulsation artifacts are prevented between still frames of the series of still frames. Partial still picture encoding to prevent pulsation artifacts on a macroblock level is also addressed.

Progressive I-slice refreshed MPEG data streams are transcoded to I-frame based MPEG data streams to enable trick play modes on a television appliance, such as pause, scan forward, scan backward, jump, or still frame displays for use, e.g., in film indexing (chapters). A progressive I-slice refreshed MPEG data stream 10 having I-slices distributed over multiple P-frames is received by a television appliance 300. The P-frames are decoded at decoder 220 to recover the I-slices which make up a complete I-frame. The recovered I-slices are assembled (e.g., by processor 230) into a complete I-frame. The complete I-frame is encoded at an encoder 250. A selected P-frame in the MPEG data stream is replaced with the encoded I-frame (e.g., via multiplexer 255) to provide an encoded I-frame based data stream 200. The I-frame based data stream is stored (e.g., in memory 240) for trick play mode use.

A display apparatus, and a display controller and an operating method thereof are provided. The display controller includes a controller, a buffer, and a compression/decompression unit. The controller receives an original frame from a host. The controller controls a display module to display the original frame provided by the host in a non-still frame mode. The compression/decompression unit is coupled between the buffer and the controller. The controller compresses the original frame to the buffer through the compression/decompression unit. If the controller operates in a still frame mode, the controller decompresses a compressed frame in the buffer to obtain a decompressed frame through the compression/decompression unit, and controls the display module to display the decompressed frame.

A videoconference system can automatically transmit first and second images from a local site to a remote site where the first image is a high-resolution live image and the second image may be transmitted either as a high-resolution live or still frame image. Two video streams representing the first and second images are transmitted together to the remote site within a single carrier channel. The second image is transmitted as a still image whenever the second image is static to conserve bandwidth.

The audio may be faded-in and one or more still frames of video data may be displayed while the video stream is retrieved. Additionally, a license for DRM (Digital Rights Management) encryption of the title content may be retrieved before starting playback of the video stream, so that the digital media content that is retrieved is also protected.

Methods and systems for separating a picture part of interest from an arbitrary background in real time videos are presented. The background may be a moving or still frame. The picture part of interest and background frames may be in or out of focus. One separation approach employs the difference between luminance and chrominance values of the input and background frames where changes in luminance from frame to frame are compensated for. In another approach, picture part of interest separation is based solely on spatial resolution differences between the background and the picture part of interest frames. The present invention also teaches a method and system for parameter matching of the picture part of interest and the basic picture into which the picture part of interest is embedded. The invention further teaches a method and system for embedding a separated picture part of interest into a basic picture containing text.
