Method and system for name-face/voice-role association

A method for providing name-face / voice-role association includes determining whether a closed captioned text accompanies a video sequence, providing one of text recognition and speech to text conversion to the video sequence to generate a role-name versus actor-name list from the video sequence, extracting face boxes from the video sequence and generating face models, searching a predetermined portion of text for an entry on the role-name versus actor-name list, searching video frames for face models / voice models that correspond to the text searched by using a time code so that the video frames correspond to portions of the text where role-names are detected, assigning an equal level of certainty for each of the face models found, using lip reading to eliminate face models found that pronounce a role-name corresponding to said entry on the role-name versus actor-name list, scanning a remaining portion of text provided and updating a level of certainty for said each of the face models previously found. Once a particular face model / voice model and role-name association has reached a threshold the role-name, actor name, and particular face model / voice model is stored in a database and can be displayed by a user when the threshold for the particular face model has been reached. Thus the user can query information by entry of role-name, actor name, face model, or even words spoken by the role-name as a basis for the association. A system provides hardware and software to perform these functions.

Standard time signal receiving time device and decoding method of time code signal

In a radio controlled clock and a decoding method of a time code signal, the time code signal can be accurately decoded irrespective of the mixture of noises and the deterioration of a radio wave signal receiving situation, and arithmetic processing is simple. A standard time signal is received and the time code signal superposed on this standard time signal is sampled at an interval of 50 ms and is stored to a memory. The stored sampling data are formed as a list in a data group every one second (20 samples). The plurality of data groups formed as a list are added every each sampling point, and a point for maximizing an increase change of the adding result is set to a synchronizing point of the sampling. Further, the correlation of the sampling data group and a code template pattern is calculated and a code shown by the sampling data group is judged.

Frame Accurate Content Insertion System

A content insertion system helps digital media providers insert replacement content (e.g., localized commercials) at precisely the right places in the video streams delivered to downstream players. Specifically, with frame accuracy, the system inserts content insertion triggers into the delivered video streams. From a source video input, the system determines the trigger positions at which insertion triggers exist with reference to house timecode. The system then locates the corresponding trigger positions in the output video stream with reference to a framecount of frames generated by a digital encoder. The system inserts corresponding content insertion triggers into the delivered video stream when it locates the corresponding trigger positions.

Iterative video teaching aid with recordable commentary and indexing

A tutorial or diagnostic aid based on the representation and iterative interpretation of visual images is taught. A teaching or diagnostic session is created by overlaying an interpretation layer via a software application onto the visual image layer and synchronizing the two with the time code of the visual image. The interpretation layer allows the reviewer to identify image areas of interest by gesture and append comments thereto in real time; i.e. images or portions of images within the visual representation playback may be identified and labeled and have the concurrent commentary associated therewith. The comments are indexed and linked to a database of similar topics. The flow of the session is recorded to show the images, deictic gestures associated therewith, and commentary associated with the gestures, to enable subsequent users to playback a session and follow the flow of thought (i.e. image identification and commentary within the original session). Iterative sessions allow additional image identification and commentary to be accomplished. Additional database access through the index may further enhance a teaching session, or provide for research sessions and report generation.

Timecoding systems, methods and data structures are described which, in some embodiments, permit a true time to be ascertained from media samples whose timecodes contain an amount of drift which can arise from having non-integer frame rates. Inventive methods incorporate the use of an offset parameter that describes a time difference between a timecode and a true time associated with a media sample. The inventive approaches can be incorporated with and used compatibly in connection with current timecoding paradigms such as SMPTE timecode and the like. Further embodiments permit timecoding to take place at the field level of a frame. This can permit true-time calculations to be done to ascertain the true time associated with individual fields of a frame. In addition, other embodiments provide novel counting compensation methods that are directed to reducing the drift that can be associated with media samples that are sampled at non-integer frame rates.

Magnetic recording/reproduction apparatus

An inputted video audio signal is temporarily memorized in a video and audio memorizing section 310. Auxiliary information appended to the video audio signal is temporarily memorized in an auxiliary information memorizing section 320. A memory control device 620 controls write and read operations of the video audio signal with respect to the video and audio memorizing section 310 and write and read operations of the auxiliary information with respect to the auxiliary information memorizing section 320. The video audio signal read from the video and audio memorizing section 310 and the auxiliary information read from the auxiliary information memorizing section 320 are sequentially recorded on a recording medium 500 by a recording device 400. The memory control device 620 stores the video audio signals equivalent to a time length equal to or exceeding an amount of time required from a time point when a recording-start request with respect to the recording medium 500 is made until the recording actually starts with respect to the recording medium 500 in the video and audio memorizing section 310 to thereby delay the video audio signals by an amount of time during which the video audio signals are stored and records the delayed video audio signals on the recording medium. The memory control device 620 further stores the auxiliary information appended to the video audio signals in the auxiliary information memorizing section 320 for a time period substantially equal to the delay of the video audio signals to thereby delay the auxiliary information by an amount of time during which the auxiliary information is stored and records the delayed auxiliary information on the recording medium 500. The video audio signal and its relevant auxiliary information (time code, metadata, CUE audio signal, and the like) can be thereby recorded on the recording medium 500 with no time delay relative to each other.

Techniques for synchronizing audio and video data in an image signal processing system

The present disclosure provides techniques for performing audio-video synchronization using an image signal processing system. In one embodiment, a time code register provides a current time stamp when sampled. The value of the time code register may be incremented at regular intervals based on a clock of the image signal processing system. At the start of a current frame acquired by an image sensor, the time code register is sampled, and a timestamp is stored into a timestamp register associated with the image sensor. The timestamp is then read from the time stamp register and written to a set of metadata associated with the current frame. The timestamp stored in the frame metadata may then be used to synchronize the current frame with a corresponding set of audio data.
