Abstract:
The disclosure is directed to a video slicing technique that promotes low complexity, bandwidth efficiency and error resiliency. A video encoder places an RM close to the beginning of each logical transmission unit (LTU) so that all but a very small end segment of each video slice fits substantially within an LTU. Instead of requiring placement of RMs exactly at the LTU boundaries, a video encoder applies an approximate alignment technique. Video slices are encoded so that RMs are placed close to the beginning of each LTU, e.g., at the end of the first MB falling within the LTU. A portion of the last MB from the preceding slice carries over into the next LTU. Loss of an LTU results in loss of virtually the entire current slice plus a very small portion of the previous slice.
