摘要:
A central database provides a location for creating and storing samples of known television commercials. The database of commercial samples is downloaded to a set-top box via a communicate link. The set-top box incorporates a processor for comparing a television signal with the database of known commercial messages to detect the presence of commercial messages. The set-top box may be used to control a recording unit to stop recording for the duration of the commercial message or flag the commercial message for muting or manual skipping during playback. Using this system, the user has the ability to positively detect commercial messages and eliminate the commercials from viewing if desired.

An image capturing system and method for automatically watermarking a plurality of recorded camera and image parameters such as the location (latitude, longitude and altitude), orientation of the principal axis of the camera, whether the camera is in landscape mode or portrait mode, camera velocity, photographer information, time and date, zoom factor, shutter speed, flash on/off, autofocus distance, lightmeter reading, focal length and aperture into every captured image. This watermarked data can be subsequently extracted and compared with the originally recorded data so as to verify the authenticity of a corresponding image. Since the critical data is invisibly watermarked into the image, it is difficult to modify the image without affecting the watermarked data.

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.
摘要:
A recording medium for storing real time recording/reproduction information, a real time recording and reproducing method and apparatus, and a file operating method using the information. Real time recording/reproduction information for ensuring real time recording/reproduction is stored in a file control information area, in each real time file, or in a separate file, and real time recording/reproduction attributes are assigned to the file. Thus, real time recorded files can be continuously reproduced without interruption. Also, there are methods of creating a file to which real time recording/reproduction attributes are assigned, extending a data area, and recording and reproducing the file to which real time recording/reproduction attributes are assigned.
摘要:
An image system which captures, along with the images, information defining both the position and the orientation of the camera along with the distance to the subject. A video camera is attached to three accelerometers, two gyroscopes, and a rangefinder. Data gathered from these devices and defining the pitch, yaw, and roll of the camera, the camera's acceleration, and the distance to the subject is captured and recorded along with video images. The video images are later stored within a computer's data base along with data defining the position and orientation of the camera and the distance to the subject for each image, this latter data being computed from the captured data. The images may then be presented to the user in a three-dimensional display in which the user can navigate through the images using a joystick device, with the images located in positions corresponding to the positions in space of the objects that were imaged.

A moving image processing unit has a sensor management unit and an attachment unit. The sensor management unit manages sensors that detect at least one of a person, an object, a movement of the person or the object, and sound information as sensor information, while a moving image is being captured. The attachment unit attaches metadata to the moving image, after checking a combination of the sensor information based on the sensor information outputted from the sensor management unit.

A video camera is used to record a picture sequence on a recording medium. A related geographic location signal provided by a GPS receiver is recorded as audio data on the recording medium concurrently with the picture sequence.

A recording medium and a recording apparatus store manufacturer information to support specific functions for each manufacturer and a method therefore. A reproducing apparatus reproduces the manufacturer information to support specific functions. When the recording apparatus modifies the contents of the recording medium, the manufacturer's identification code is recorded. The recording apparatus and the reproducing apparatus checks the identification code on the recording medium before using its own manufacture information item for some specific function. Also, a time required to determine whether the manufacturer information items are effective is reduced.
摘要:
A method for generating a programme for presentation to a user such that the presented programme is made up from a sequence of programme elements each of which is a programme clip taken from at least one distributed programme and each of which represents an event. Each programme element is classified on the basis of the event represented by the programme element. Each programme element is stored with at least one associated programme element classification code, and each classification code identifies a class to which the event represented by the associated programme element has been allocated. A programme is assembled for presentation to the user by selecting at least one programme classification code, and generating an assembled programme in the form of a sequence of programme elements associated with the at least one programme classification code. Programme elements are classified using a set of event classes including a plurality of subsets of the event classes. Classification of each programme element comprises a classification operator malting at least one selection from at least one of the subsets, said selection determining at least one of the subsets from which future selections can be made. The at least one selection generates the classification code associated with the programme element.
