....correlations from frame to frame in an image sequence, while spatial compression attempts to eliminate 5 redundancies by exploiting statistical correlations within a given frame. Our algorithm employs a very simple model for temporal compression known as block based conditional replenishment [24, 25], and uses a hybrid DCT subband transform coding scheme for spatial compression. In the next section, we describe the conditional replenishment algorithm and in the subsequent section, we describe the spatial compression algorithm. 3.1 Temporal Compression In block based conditional ....

....format desired by the encoder. Unfortunately, manipulating video data in the uncompressed domain results in a substantial performance penalty, so we have optimized the capture path by supporting each format. A further performance gain was realized by carrying out the conditional replenishment [32] step as early as possible. Most of the compression schemes utilize block based conditional replenishment, where the input image is divided up into small (e.g. 8x8) blocks and only blocks that change are coded and sent. The send decision for a block depends on only a small (dynamically varying) ....

Analysis of Block-Based Locality in Digital Video - Nguyen (1994) (Correct)
....and sends only the difference between the current pixel and the previous pixel. Because of the high amount of locality (or strong correlation) 5 existing between the pixels, the difference is usually small. Thus the number of bits required per pixel is reduced. In conditional replenishment [6] [7] adjacent frames are compared, and only those areas that changed are processed and sent. This idea works because there is a large amount of temporal redundancy in many types of video, especially in head and shoulder scenes prevalent in videoconferencing. Motion compensation [5] is a further ....
....to show examples of how locality can be used. Detail descriptions of the examples are beyond the scope of this thesis. 4.1 Predictive Sampling 4.1. 1 Motivation To reduce bandwidth and subsequent processing of static data, many video encoding systems use a scheme called conditional replenishment [6] [7] This scheme basically involves comparing adjacent frames and processing only the data that has changed. But in order to find out which parts of the frame have changed, it is necessary to bring in the entire frame from the frame grabber into memory to compare with the previous frame. This ....
