  • Publication number: 20080195823
    Abstract: The invention relates to the processor for performing convolution interleaving/de-interleaving on data symbols on plural original data symbols and convolution de-interleaving on the convolution interleaved data symbols. The processor for performing convolution interleaving on data symbol comprises a memory, an original address generator, and a storage address generator which generates an original address. The storage address generator generates the storage address of each of the stored plural data symbols in the memory according to the original address and a first predetermined sequence, and each of the convolution interleaved data symbols is stored in the memory according to the storage address; furthermore, all stored data symbols in the memory are configured into a circular structure.

  • Publication number: 20080086491
    Abstract: Apparatus for playing and managing multimedia items include a primary storage, a browser and a converter. The converter is used for converting multimedia items from a first item type to a second item type. The browser provides a unified operating interface for accessing multimedia items of both the first item type and the second item type. By dynamically converting the item type of the multimedia items on the primary storage, a better user experience is provided even the capacity of the primary storage is limited.
