摘要： In various embodiments, a unidirectional broadcast network is utilized to provide digital content to users in a manner that allows users' computing devices to maintain synchrony with personal, relevant information. In at least some embodiments, the broadcast network utilizes a data channel and a signaling channel. The data channel is used for broadcasting data to various users, while the signaling channel typically used for transmitting device or machine specific data-is used to transmit user-specific information associated with the information or data that the user finds relevant. This user specific information can then be used by the user's mobile computing device to manage, e.g. record and place into device database for time shifted retrieval, such information or digital objects delivered over the broadcast data channel.

摘要： A method for reducing arbitrary-ratio up-sampling operation using context of macroblock, and a method and an apparatus for encoding/decoding by using the same are provided to reduce the operation quantity of an enlargement calculation by using the information of the peripheral block in a scalable video encoding and decoding. An arbitrary macroblock is selected to successively examine a mode of each macroblock of the lower layer(S510). It is determined at least the selected macroblock or a peripheral macroblock is an intra macroblock(S520). If one of the macroblocks is the intra macrobloc, the selected macroblock is enlarged(S530). It is determined whether a mode investigation is finished for all macroblocks of the lower layer image(S540). If the adaptive enlargement process for all macroblocks is completed, the encoding of the higher layer image is performed.
