Abstract:
A video receiver is operable to receive three-dimensional (3D) video bitstreams from a video transmitter. The received 3D video bitstreams comprises a plurality of video frames and corresponding coding information. The coding information, for example, block motion vectors, block coding modes, quantization levels, and/or quantized residual data, is extracted for performing frame-rate up-conversion on the received plurality of video frames. The coding information is generated at the video transmitter via entropy decoding on a compressed 3D video from a video feed from, for example, an IP TV network. When an uncompressed 3D video is received, the video receiver is operable to perform frame-rate up-conversion on the received uncompressed 3D video using extracted block motion vectors and associated confidence-consistence measure. When a compressed 3D video is received, the video receiver is configured to perform video decompression on the received compressed 3D video prior to the frame-rate up-conversion.
