Embodiments of the present invention disclose a method and an apparatus for detecting frame types. The method includes: detecting play time of each frame; and if the play time of a current frame is less than the maximum play time of received frames, determining the current frame as a bi-directional predicted frame, B-frame. In the technical solutions provided by the embodiments of the present invention, the frame types are determined according to a coding sequence of various frames and comparison between data amounts of various frames received earlier and later, without decoding a payload. Therefore the impact of a reduction factor is eliminated and the frame types can be detected more accurately.

Method and apparatus for detecting frame types

In one embodiment a method includes connecting a primary video conference client device (PVCCD) to a video conference session; allocating: at least a first presentation segment of the video conference session to be presented by the PVCCD, and also allocating at least a second presentation segment of the video conference session to be presented by at least one secondary video conference client device (SVCCD), receiving a data stream associated with at least the first presentation segment, and presenting the first presentation segment on the PVCCD.

In one embodiment, video is transmitted between a sending device and a receiving device. The sending device is configured to receive adjacent camera views and encode the adjacent camera views independently into video streams. The sending device performs an image analysis on the adjacent camera views in order to generate a projection matrix to relate the adjacent camera views. The projection matrix and the encoded video streams are sent to at least one receiver. The receiver is configured to receive the encoded video streams and the projection matrix relating the encoded video streams. The receiver calculates an aggregate video stream using the projection matrix. The aggregate video stream includes portions of at least two of the encoded video streams. Other receivers may receive the same encoded video streams and generate a different aggregate video stream having a varying size, resolution, or number of views.
