Multiple video recordings may be synchronized using audio features of the recordings. A synchronization process may compare energy tracks of each recording within a multi-resolution framework to correlate audio features of one recording to another.

Embodiments are provided for syncing multiple electronic devices for collective audio playback. According to certain aspects, a master device connects (218) to a slave device via a wireless connection. The master device calculates (224) a network latency via a series of network latency pings with the slave device and sends (225) the network latency to the slave device. Further, the master devices sends (232) a portion of an audio file as well as a timing instruction including a system time to the slave device. The master device initiates (234) playback of the portion of the audio file and the slave devices initiates (236) playback of the portion of the audio file according to the timing instruction and a calculated system clock offset value.

Methods and systems for managing content items are described. A content item may be separated into components, such as chroma components, luminance components, and audio components. For more efficient management of the content, including for storage and delivery of the content, the separate components may be stored at different locations. For example, chroma components may be stored on a central server, while luminance and audio components are stored at other locations, such as edge servers, or vice versa, to accommodate network efficiency considerations. When content is delivered to a player, two or more separate streams carrying different content components may be delivered to the player.

A comnunication system includes a transmission terminal and a reception terminal. One of the transmission terminal and the reception terminal includes a processor. The processor is configured to calculate an adjustment value indicating a difference between an imaging cycle and a display cycle. The processor is configured to cause the imaging cycle and the display cycle to match each other by adjusting a signal generator on the basis of the adjustment value. A connection history in which adjustment information and identification information of a communicator are associated with each other is recorded on a recording medium. The processor is configured to adjust the signal generator on the basis of the adjustment value indicated by the adjustment information when the first communicator and the second communicator connect to each other again.

A digital jukebox allows for playback of a first offering and a second offering. The contents of each offering are individually licensed for public performance at a particular location where the jukebox is found. The jukebox displays advertisements that are selected in response to user interaction with the jukebox or a number of other factors. The jukebox features a screen that allows user to interact with the jukebox to select offerings, but also to respond to advertising. Jukebox can function in cooperation with a server, but in the alternate, can function as an independent and stand-alone device when connection to server is not available.

A control device includes: generation circuitry configured to output a field signal to a medical imaging device; first detection circuitry configured to detect a horizontal synchronization signal from video data output from the medical imaging device, the video data including at least the horizontal synchronization signal; and a monitoring circuitry configured to monitor whether or not an abnormality occurs in one frame period of the video data based on a period of the horizontal synchronization signal detected by the first detection circuitry for a predetermined n-th time after polarity of the field signal is switched.

Vehicle event data playback systems described herein may provide users means for reviewing events recorded by a vehicle event recorder. Circumstances relating to vehicle operation may be visually presented in these playback systems. Video playback from multiple recording devices may be synchronized with each other and/or with information related to the operation of the vehicle during the recorded events to affect a presentation of information related to operation of the vehicle. A user may be presented with many data types in graphical and/or intuitive arrangements.
