Abstract
A method of video conferencing among two or more video conference endpoints is provided, wherein the method comprises steps of: processing media data of the video conference into unified coding formats while switching media data of the video conference between the two or among more video conference endpoints; and saving the processed media data into recording files of continuous presence mode and lecture mode, wherein the recording file of continuous presence mode saves media data generated by the two or more video conference endpoints, the recording file of lecture mode saves media data generated by a video conference endpoint who is the lecturer in the video conference. Accordingly, a device of video conferencing is provided.
Claims30
A method of video conferencing among two or more video conference endpoints, comprising steps of:
- processing media data of a video conference into a unified coding format while switching media data of the video conference among two or more video conference endpoints;
- and
- saving the processed media data into at least two recording files, a first recording file corresponding to a continuous presence mode and a second recording file corresponding to a lecture mode, wherein the first recording file corresponding to a continuous presence mode saves media data generated by the two or more video conference endpoints, and the second recording file corresponding to a lecture mode saves media data generated by a video conference endpoint who is a lecturer in the video conference.
A video conferencing device comprising:
- a network interface module configured to receive and transmit media data;
- a switching module configured to switch the media data;
- a backend transcoding module configured to process the media data into a unified coding format and save the processed media data into at least two recording files, a first recording file corresponding to a continuous presence mode and a second recording file corresponding to a lecture mode;
- and
- a storage module configured to save the recording files;
- wherein the first recording file corresponding to a continuous presence mode saves media data generated by the two or more video conference endpoints, and the second recording file corresponding to a lecture mode saves media data generated by a video conference endpoint who is a lecturer in the video conference.
A method of recording a video conference, the method comprising receiving and processing one or more media streams from each of a plurality of endpoints and saving the processed media streams into at least two recording files, a first recording file corresponding to a continuous presence mode and a second recording file corresponding to a lecture mode;
- wherein:
- saving the processed media stream into the first recording file corresponding to the continuous presence mode comprises:
- storing a composite audio stream, wherein the composite audio stream is a combination of two or more audio streams from the received one or more media streams from each of the plurality of endpoints;
- and
- storing a composite video stream, wherein the composite video stream is a combination of two or more video streams from the received one or more media streams from each of the plurality of endpoints;
- and
- saving the processed media stream into the second recording file corresponding to the lecture mode comprises:
- storing a composite audio stream, wherein the composite audio stream is either:
- a combination of two or more audio streams from the received one or more media streams, or a selected audio stream from the received one or more media streams from each of the plurality of endpoints;
- and
- storing a selected video stream, wherein the selected video stream is a video stream from the received one or more media streams from each of the plurality of endpoints.
