This disclosure describes techniques for region-of-interest (ROI) encoding. In accordance with the techniques described herein, an encoding device may determine a temporal spatial dependency value for a candidate reference video block for inter-coding a current block in a video frame. The encoding device may compare the temporal spatial dependency value to a threshold value and select a coding mode for the current block based on the comparison. A decoding device may receive data defining a ROI as well as the temporal spatial dependency value and decode a video block in the ROI based at least in part on the temporal spatial dependency value. In this manner, the techniques of this disclosure may allow a video content viewer the ability to choose a ROI to watch.

Systems, methods, and devices that facilitate finite-precision data accumulation by utilizing precision binning and queuing are provided. A precision range of a data element received into a queue can be determined. Further, a stored data element of like precision can be selected. The stored data element can be added with the data element received into the queue to generate a resultant data element. The resultant data element can be stored in a memory location or the queue as a function of like precision range.

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.
