Abstract: An electronic device is provided. The electronic device includes a housing, a display configured to be exposed through one surface of the housing, a communication module configured to communicate over a first network compliant with a first protocol or a second network compliant with a second protocol, a processor configured to be electrically connected with the display and the communication module, and a memory configured to be electrically connected with the processor and store a specified application.

Abstract: An input video stream of video content may be encoded and transmitted from a provider to an intermediary, which decodes and edits the video content, and then re-encodes and transmits the video content to end viewers via an output video stream. When re-encoding the video content, the intermediary may determine to selectively re-use and/or not re-use input motion vectors from the input video stream, for example based on an amount of distortion associated with editing of the video content. In some examples, input motion vectors may be re-used for re-encoding of certain portions (e.g., frames, parts of frames, etc.) of the output video stream and not re-used for re-encoding of other portions of the output video stream.

Abstract: Techniques for estimating speed for an object in a video (either stream or file) are described. In particular, once an object has been recognized, additional data (such as size) for that recognized object is used in a determination of a 3D position of that object in a plurality of frames. An estimated speed may be found using a difference between 3D positions of the object in different frames over the time between the frames.
