摘要： The invention relates to a device for generating a video output data stream, comprising a first and a second signal input for receiving a first and a second video source data stream, and a processor device that is designed to provide the video output data stream at a first time, based on the first video source data stream, and to provide same at a second time by means of a shifting process, said second time following the first time, based on the second video source data stream. The device also comprises a control signal output for sending a control command to a video source, from which the first or second video source data stream is received. The control command comprises an instruction to the video source for the use of a transition effect that is arranged chronologically between an image of the first video source data stream and an image of the second video source data stream in the video output signal.

摘要： The object of the present invention is to switch between a plurality of sets of waveform data at desired timing while preventing occurrence of noise. In response to an instruction for switching from a currently reproduced set of waveform data (20) to another set of waveform data (20'), either a switching position in the other set of waveform data (20') or a switching in the currently reproduced waveform data (20) is set as end timing for ending the reproduction of the currently reproduced set of waveform data (20), with reference to switching position information (25) of the two sets of waveform data. If the switching position in the currently reproduced set of waveform data (20) is present within a 50 msec time range before a switching position in the other set of waveform data (20') that is present immediately after the switching instruction, the switching position in the currently reproduced set of waveform data (20) is set as the ending; if not, the switching position in the other set of waveform data (20') is set as the end timing.

摘要： Systems and methods for mixing music are disclosed. Audio mix information is received from a plurality of users. Mix rules are determined from the audio mix information from the plurality of users, wherein the mix rules include a first mix rule associated with a first audio item. The first mix rule relates to an overlap of the first audio item with another audio item. The first mix rule is made available to one or more clients. In some implementations, making the first mix rule available to the one or more clients includes transmitting, to the first client, information enabling the first client to playback a transition (e.g. crosss-fading) and a musical effect (e.g. reverberation) between the first audio item and a second audio item in accordance with the first mix rule.

摘要： The audio signal mixing device may be applied to a DJ equipment, for example. The audio signal mixing device obtains multiple audio signals, and obtains mixing ratio information which is information related to the mixing ratio of the multiple audio signals. The audio signal mixing device determines adjustment amounts of the inter-frequency-range level balance in a case that the multiple audio signals are mixed by the mixing ratio. Then, the audio signal mixing device mixes the multiple audio signals separately for each of the frequency ranges, adjusts the levels of the mixed signal for each of the frequency ranges, and adds the signals of each of the frequency ranges after the adjustment to output it as a mixed audio signal.

摘要： A video switcher (10) advantageously affords the capability of executing a video effect following recall that avoids visible artifacts upon transitioning from one effect to another. At the outset, the switcher identifies active elements within the video effect, the comprising those elements that undergo a change during execution of the video effect, as opposed to those that remain inert during effect execution. The switcher then dynamically calculates offset for application to an initial key frame value for the video effect to avoid any change in value to active elements upon initial effect recall. The offset value is applied to each subsequent interpolation of the video effect, thereby creating the desired result of applying only relative changes to the active elements of the video effect.
