The present disclosure provides a method and a device for synchronization between a video frame and an audio frame on the basis of high-speed transmission of a VoD content. A content delivery server includes a transceiver and a processors. The transceiver receives, from a content requesting terminal, a search request for a specific playback time within a VOD content. In response to the search request, the processor deletes one or more audio frames existing between a video frame that corresponds to the requested playback time and an audio frame that corresponds to the requested playback time; and generates content data reconstructed to include all or part of frames existing in a period of time from the video frame that corresponds to the requested playback time to the audio frame that corresponds to the requested playback time. The transceiver transmits the reconstructed content data to the content-requesting terminal.

The application provides an animation progress driving business linkage method and system for a ktv interactive scene, which comprises the following steps: configuring a linkage time event table based on a business system; starting ktv animation playing and recording an animation starting time stamp; taking a system clock as a reference to calculate a current system time, and calculating a ktv animation playing progress according to the current system time and the animation starting time stamp; using a development graphics library OpenGL to render an animation frame, comparing the ktv animation playing progress with an animation playing time point of the linkage time event table, triggering a business operation instruction when the ktv animation playing progress hits the animation playing time point, and distributing the business operation instruction to a corresponding business system in a VOD video on demand system in a non-blocking manner through an asynchronous event bus to execute corresponding ktv business operations. The application considers both smooth animation playing and millisecond-level precision business triggering, maintains time synchronization and business correctness in abnormal conditions, and reduces the coupling degree between the animation and the business system.

An interactive media system is provided. The interactive media system allows users to access applications via communication devices coupled to a communication network. At least a portion of the network may be wireless. The interactive media system applications include wagering, financial, entertainment service, and other types of transactions. The system may be built into or overlaid on stream video on demand platforms.
