Technical Examples
- A method, system, and apparatus for easily creating a video collage from a video is provided. By segmenting the video into a set number of video segments and providing an interface for a user to select images which represent the video segments and insert the selected images into a video collage template, a video collage may be easily created in a short amount of time. The system is designed to assign values to the video inserted in a video collage and compact the video based on these values thereby creating a small file which may be easily stored or transmitted.
- Methods and apparatus for switching between a live video decoding and a recorded playback in a digital video and recording system. A received video data stream is transmitted to a first-in first-out video decoder buffer without first looping the video data stream through a playback buffer. The video data stream is transmitted from the video decoder buffer to a video decoder. If a "pause" command is received, the video data stream is transmitted to a first-in first-out playback buffer, while continuing to transmit the video data stream to the video decoder buffer. Transmission of the video data stream to the video decoder buffer is halted when the video decoder buffer fills up. The last byte of the video data stream that was transmitted to the video decoder buffer is marked. If a "play" command is received, the video data stored in the video decoder buffer is transmitted to the video decoder. The video data stored in the playback buffer is transmitted to the video decoder buffer starting at a point immediately after the data element that was marked previously.
- Provided are decoding methods and decoders for calculating comb filter error and performing comb filter calculation used for decoding video signals. In one aspect, a method of calculating comb filter error used for decoding a video signal comprises storing a plurality of consecutive video lines of the video signal, the plurality of consecutive video lines including a first video line, a second video line appearing immediately before the first video line, and a third video line appearing immediately before the second video line; receiving a current video line of the video signal, wherein the current video line appears immediately after the first video line; obtaining a first difference between the current video line and the second video line; obtaining a second difference between the first video line and the third video line; and filtering the video signal for separating components in the video signal, based on the differences.
- A video thumbnail for use as an icon of a digital video file and method of generating same. The video thumbnail is preferably a relatively short, low resolution, animated video thumbnail. The video thumbnail is extracted from a preferred sequence of the video file and embedded as a header of the file. The video thumbnail preferably plays automatically, and acts as a pointer to the file and the preferred point within it.
- Systems and methods for transcoding a video stream. An incoming video stream is spatially transcoded to reduce the bit rate of the video stream. The incoming video stream is decoded and the stream parameters are saved for use in generating the output video stream. The decoded video stream is resampled and the images are spatially reduced. Using the stream parameters of the incoming video stream, an outgoing video stream is generated. Some of the stream parameters are unchanged while others are re-computed for the outgoing video stream.
