Abstract: Various embodiments of the invention disclosed herein provide techniques for frame-accurate navigation of a media file. A multi-pass encoding application executing on a media content server encodes a set of file-based images associated with a media file using a first set of encoding parameters to generate a first encoded media file. The multi-pass encoding application encodes the first encoded media file using a second set of encoding parameters to generate a second encoded media file. The first encoded media file and second encoded media file are stored on the media content server and/or or other media content servers. Content delivery applications executing on these media content servers receive a request associated with the media file from a web browsing application, determine a type of the web browsing application, and transmit either the first encoded media file or the second encoded media file based on the type of web browsing application.

Abstract: An embodiment of a method for accessing a storage unit of a flash memory, performed by a processing unit, includes at least the following steps. After a notification indicating that errors presented in a message of a sector within a RAID (Redundant Array of Independent Disk) group cannot be fixed by an error correction algorithm with a horizontal ECC (Error Correction Code) of the sector is received, addresses of the other sectors within the RAID group are determined. Information is provided to a sector-decoding unit and a RAID-decoding unit, which indicates that a vertical correction procedure has been activated. Storage-unit access interfaces are directed to read content from the determined addresses of the storage unit, thereby enabling the RAID-decoding unit to recover the message of the sector by using the read content.
