摘要： Encoding of a plurality of encoded symbols is provided wherein an encoded symbol is generated from a combination of a first symbol generated from a first set of intermediate symbols and a second symbol generated from a second set of intermediate symbols, each set having at least one different coding parameter, wherein the intermediate symbols are generated based on the set of source symbols. A method of decoding data is also provided, wherein a set of intermediate symbols is decoded from a set of received encoded symbols, the intermediate symbols organized into a first and second sets of symbols for decoding, wherein intermediate symbols in the second set are permanently inactivated for the purpose of scheduling the decoding process to recover the intermediate symbols from the encoded symbols, wherein at least some of the source symbols are recovered from the decoded set of intermediate symbols.

摘要： The switch signaling methods providing improved switching between representations for adaptive HTTP streaming described herein enable user experience and bandwidth efficiency improvements for adaptive HTTP streaming solutions, even when segment data is encrypted. The signaling methods include associating segment maps with segments of a representation, wherein a segment map comprises both temporal entry and temporal exit points within associated segments together with byte offset information and potentially other segment information, wherein segment maps may be generated with predictable time span patterns that are independent of the time spans of the associated segments. These embodiments can be used to enhance existing deployments in such a way that there is no need to change existing content encoding and formatting processes, and such that existing clients that receive and play out content are unaffected.
