X-Git-Tag: submit/tizen/20200220.043100~8 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9db000f2b395b959f364273710f6228eb50f8503;p=platform%2Fupstream%2Fnnstreamer.git Aggregator/Doc: add dis-aggregator notes. Per the request on the usage of "dis-aggregator", leave a note that it is already supported by aggregator.

(See the property ```frames-dim```.) +### Dis-aggregation + +With larger ```frames-in``` values and smaller ```frames-out``` values, the output stream may have more frames than its input stream: ```dis-aggregation```. +For example, if a neural network model multiplies picture frames of a video stream, generating 120FPS from 30FPS video, aggregated in a single video (in tensor format) stream output, we can generate a 120FPS stream from a 30FPS (4 frames per buffer) stream. If the model generates 4 video (tensor format) streams with other/tensors, we may merge them first and apply aggregator for the same effect. + ## Sink Pads One "Always" sink pad exists. The capability of sink pad is ```other/tensor```.
