Recording apparatus, recording method, reproduction apparatus, reproduction method, recording medium, encoding apparatus, and decoding apparatus
There is provided a recording apparatus, a recording method, a reproduction apparatus, a reproduction method, a recording medium, an encoding apparatus, and a decoding apparatus which enable recording or reproduction to be easily implemented at high line density. User data is encoded into a multilevel edge code, and a multilevel code whose value changes in accordance with the multilevel edge code is recorded. The multilevel edge code is generated through state transition of a code generation model which includes a state representing the number of times that zero is consecutive corresponding to a number of ways of the number of times that zero is consecutive, which is the number of times that an edge of 0 is consecutive among edges representing a change amount from an immediately preceding value of the multilevel code of an ML value which is equal to or greater than 3, and which transitions to a state representing the number of times that zero is consecutive including 0 in a case where 0 is output, and transitions to a state representing that the number of times that zero is consecutive is 0 times in a case where one of 1 to ML−1 is output.
System and method for enhanced video image recognition using motion sensors
Disclosed are systems and methods for improving image recognition by using information from sensor data. In one embodiment, the method comprises receiving one or more sensor records, the sensor records representing timestamped sensor data collected by a sensor recording device; selecting an event based on the sensor records; identifying a time associated with the event; retrieving a plurality of timestamped video frames; synchronizing the sensor records and the video frames, wherein synchronizing the sensor records and the video frames comprises synchronizing the timestamped sensor data with individual frames of the timestamped video frames according to a common timeframe; and selecting a subset of video frames from the plurality of timestamped video frames based on the selected event.
Systems and methods for generating a video summary
Systems and method of generating video summaries are presented herein. Information defining a video may be obtained. The video may include a set of frame images. Parameter values for parameters of individual frame images of the video may be determined. Interest weights for the frame images may be determined. An interest curve for the video that characterizes the video by interest weights as a function of progress through the set of frame images may be generated. One or more curve attributes of the interest curve may be identified and one or more interest curve values of the interest curve that correspond to individual curve attributes may be determined. Interest curve values of the interest curve may be compared to threshold curve values. A subset of frame images of the video to include within a video summary of the video may be identified based on the comparison.
Movie advertising playback systems and methods
An ad in a movie can be a static ad having a position in the movie that cannot be moved, or a dynamic ad having a position in the movie that can be changed. When a viewer wishes to skip a portion of the movie containing the ad, the playback system determines whether the ad is static or dynamic. If the ad is static, only the portion of the movie preceding the static ad can be skipped; the ad is unskippable. This technique is referred to as “bounceback” since the end of the skip bounces back to the start of the static ad. If the ad is dynamic, it is moved to after the end of the skip. This technique is referred to as “slip-ad” since the ad slips to later in the movie. When a movie has multiple ads, some can be static and some can be dynamic.
METHODS AND APPARATUS FOR MONITORING THE INSERTION OF LOCAL MEDIA INTO A PROGRAM STREAM
Methods and apparatus for monitoring locally inserted media are disclosed. A disclosed apparatus includes instructions to detect, at a media device at an end user location, a frequency of a watermark that was spliced into a primary media stream received at the media device after the primary media stream was received at the end user location, associate identifying tags with segments of the primary media stream that were spliced, in response to the detection of the watermark, determine an advertisement associated with the segments of the primary media based on the identifying tags, present the primary media at a first time and the advertisement at second times, record a log including first identifying information including an identity of the content of the primary media and second identifying information including a change in the frequency of the watermark corresponding to the advertisement; and transmit the log to a data collection facility.
Chunk header incorporating binary flags and correlated variable-length fields
Playback and distribution systems and methods for multimedia files are provided. The multimedia files are encoded with flags associated with the content data of the multimedia files. Through the use of the flags, playback of the content is enhanced without significantly increasing the file size of the multimedia file.

Biometric notification system
The present invention provides a biometric notification system for selectively sending messages to interested recipients. In various embodiments, message trigger criteria, interested recipients, and message content may vary depending upon, among other things, the service being provided.
Event-triggered video creation with data augmentation
A method for creating a video that is generated based on the occurrence of pertinent events within a period of time. This video may be a summary video that includes video segments from multiple sources. The video may be augmented to display data describing pertinent events that occur.
