20120237189 | Method and system for DVD smooth rewind - Aspects of performing smooth backwards playback in a DVD system are described. The aspects include reconstructing frame data for every frame in a set of frames of an original playback, the set of frames preceding a currently displayed frame. Further included is the utilization of at least seven frame buffers to store frame data during the reconstructing step. The reconstructed frame data is then displayed in reverse order of the original playback for the set of frames. | 09-20-2012 |

20100146198 | OPTIMAL POWER USAGE IN DECODING A CONTENT STREAM STORED IN A SECONDARY STORAGE - Decoding a content of interest with optimal power usage. In an embodiment, a central processing unit (CPU) retrieves the frames of a data stream of interest from a secondary storage and stores them in a random access memory (RAM). The CPU forms an index table indicating the locations at which each of the frames is stored. The index table is provided to a decoder, which processes the frames in sequence to recover the original data from the encoded data. By using the index information, the power usage is reduced at least in an embodiment when the decoding is performed by an auxiliary processor. | 06-10-2010 |
