The method may include generating an encoded audio signal. The method may include receiving metadata from a user about an event. The method may also include generating a unique identifier (ID) that is associated with the metadata. The method may also include providing the metadata and the unique ID to a database. The method may also include encoding the unique ID in an audio signal using a robust signal modulation scheme. The method may also include playing, using a mobile device, the audio signal, where the audio signal is played within an audible detection range of recording devices configured to record the audio signal.

A first video signal having a first frame rate optionally settable is generated by an image pickup device, and the first video signal is memorized in a memory and outputted from the memory. A write control device controls the write of the first video signal with respect to the memory, and a read control device controls the read of the video signal with respect to the memory. The write control device writes respective first frame data constituting the first video signal in the memory in each cycle determined by the first frame rate of the first video signal. The read control device reads the first frame data as a second video signal. The second video signal is formed from sequentially arranging the first frame data in a partially duplicating manner in a standard video signal having a standard frame rate based on a determined arrangement rule. The predetermined arrangement rule is an arrangement rule employed when respective frame data constituting a video signal having a second frame rate equal to or lower than the standard frame rate are arranged in a duplicating manner in the standard video signal. In the foregoing manner, an time elongation/contraction effect on an image can be speedily and inexpensively obtained.

Embodiments of the present disclosure disclose a method and a system for presenting a video segment, wherein the method includes: for an online video, determining playing starting time of an effective video segment according to occurrence time of video comments and the number of occurrences of the video comments during playing of the online video; obtaining the effective video segment according to the playing starting time of the effective video segment and a playing duration; presenting the effective video segment in a video segment list of the online video.

Disclosed is a system communicating with a communication network for manipulating a received file. The system includes a central processor, a display unit coupled to the processor, a central memory unit coupled to the central processor to store the video file. The central processor is operable to convert the video file to a sequence of frames, followed by separation of the sequence of frames into individual frames, further followed by encoding each frame to allow user control for creating a package of frames. The central processor is further processed to display the video file through the display unit on decoding the package of frames, followed by displaying the individual frames of the video file through the display unit on receiving a tap of the user, and lastly followed by manipulating the individual frames to view in all directions of the video file on receiving instructions from the user.

A video management system is configured to include plural terminal devices, a drive recorder to be mounted in a vehicle, and a management apparatus. The management apparatus stores the set of corresponding data generated by a generation unit, determines, upon receipt of a replay request including a piece of identification information, whether or not a piece of identification information associated with a set of video data that is a target of the replay request agrees with the piece of identification information included in the replay request, and permits a transmission source of the replay request to replay the set of video data in a case where it has been determined that these pieces of identification information agree with each other.

Systems and methods for interactive playback of a video conference are provided. A request is received for a playback of a video conference between a plurality of participants of a plurality of client devices that each generated one of a plurality of source video streams, where each source video stream was presented during a live stream of the video conference according to a particular layout in a user interface (UI) on a first client device of the plurality of client devices. Playback of the video conference is caused at a second client device, wherein causing playback of the video conference comprises transmitting, to a second client device, each source video stream of the plurality of source video streams for visual rendering according to the particular layout in a UI on the second client device; and capturing a first set of user interaction events associated with one or more time points during playback of the video conference, wherein each user interaction event of the first set is visually rendered at a corresponding time point during playback of the video conference.

An athletic parameter measurement device worn by an athlete during an athletic activity session includes a housing which attaches to the athlete, a display, a processor associated with the display, and an athletic parameter measurement sensor. During the athletic activity, the device detects, using the sensor, a vertical jump height of the athlete, and displays, during the performance of the athletic activity session, a representation of the vertical jump height on the display.

A broadcast service receiving method of a broadcast receiving device is provided. The method includes: receiving a trigger; receiving a triggered object; when a target of the received trigger is the triggered object, performing a trigger action on the triggered object at a trigger time; receiving real-time data available for the triggered object by an operation of the triggered object according to the performing of the triggered action; and providing a service by using the real-time data.

It is possible to accurately and securely execute conversion from an MPEG-2TS format to an MP4 format. A data converting unit that executes format conversion from an MPEG-2TS format to an MP4 format sorts out TS packets storing video data from MPEG-2TS format data, selects a TS packet having a start code (SC) at the top of a payload on the basis of header information of the sorted out TS packets, and extracts payload configuration data other than the start code (SC) and sets the payload configuration data as configuration data of MP4 format data. The data converting unit determines, on the basis of, for example, a value of a transport priority set in a header of the TS packet, whether or not the TS packet is a TS packet in which a start code (SC) is set in a top region of a payload.

The present invention provides a testing system for a video and audio reproduction system, the testing system comprising a data source, comprising video and audio data for reproduction by the video and audio reproduction system, the video and audio data comprising unique marks in every video frame and every audio frame, a recording unit, configured to record a video stream and an audio stream generated by the video and audio reproduction system based on the video and audio data, and a test processor, configured to extract the unique marks from the recorded video stream and the recorded audio stream, and to verify if respective unique marks of simultaneous video frames and audio frames have been recorded by the recording unit simultaneously. Furthermore, the present invention provides a testing method, a computer program product, and a non-transitory computer readable data carrier.
