Embodiment Construction

[0058] Figure 4 Shows the minimum configuration of a device for selectively decoding at least one predetermined data unit from the received coded bit stream c, without decoding the complete received coded bit stream c, and does not use The directory provided in the header of the received encoded bitstream. For the purpose of simplification, this device is referred to as decoder 100 below. The components and connections drawn with solid lines are indispensable components of the decoder 100. In detail, these essential components are the parsing unit 120 and the decoding unit 130. The parsing unit 120 starts searching for information u about at least one predetermined data unit in the received coded bitstream c p , And the information u p Analyze. The parsed information can be the bit position of the predetermined data unit in the received encoded bit stream c, a suitable code sequence that clearly identifies the predetermined data unit, or any other suitable code sequence that...

Abstract

A decoder (100) is disclosed, which selectively reconstructs at least one predetermined data unit out of a coded bit stream (c). The decoder (100) includes a parsing unit (120) to search and parse unambiguous information (up) characterizing the at least one predetermined data unit uniquely. Next, the parsing unit (120) provides this parsed information (up) either directly to a decoding unit (130)or to a look-up table (140) such that the decoding unit (130) could reconstruct the predetermined data unit directly out of the coded bit stream (c) based on the parsed information (up) without decoding and reconstructing the coded bit stream (c) completely. Optionally, a specification unit (110) provides an start position (us) of the coded bit stream (c) to the parsing unit (120) used for starting the search. Therewith, data traffic, computation time and memory resources could be saved for decoding and displaying e.g. compressed JPEG pictures.

Description

Technical field [0001] The present invention relates to a decoder and a decoding method for selectively decoding at least one predetermined data unit from an encoded bit stream. In addition, it also relates to a device with a display having a lower resolution than the image encoded in the encoded bitstream. Background technique [0002] Encoding schemes are well known in the art. For several purposes, coding schemes are used to transform information into a more efficient structure. For example, a compression coding scheme is used to minimize the size of data including information, and a transmission coding scheme is used to increase the difference in information. Other important purposes can be to optimize energy, improve the recognition of information, or improve its robustness to external influences. [0003] Combine the information bit stream from the code sequence. The code sequence is a predetermined data bit sequence as the most basic interpretable information unit to mec...
