  • System and method for adaptive intra refresh rate setting in a video encoder
    Patent number: 8477846
    Abstract: A system and method for adaptive intra refresh rate setting for each video frame in a video encoder is disclosed. In one embodiment, a video encoding method includes computing channel induced distortion values at multiple intra refresh rates for a coded video frame as a function of channel loss and spatiotemporal content, computing source coding distortion values at the multiple intra refresh rates for the coded video frame as a function of the spatiotemporal content and an operating bit-rate, selecting an intra refresh rate value for one or more video frames subsequent to the encoded video frame as a function of the sum of the corresponding computed channel induced distortion values and the source coding distortion values, and encoding the one or more video frames using the selected intra refresh rate value.

  • METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR SUMMARIZING MULTIMEDIA CONTENT
    Publication number: 20120082431
    Abstract: In accordance with an example embodiment a method and apparatus is provided. The method comprises calculating an attribute for a set of encoded frames of a multimedia file. A frame attribute of at least one encoded frame of the set of encoded frames is compared with a threshold value, which is based on the attribute for the set of encoded frames. An encoded frame of the set of encoded frames is selected as a primary summary file of the multimedia file based on the comparison of the frame attribute of the at least one encoded frame with the threshold value.
