Embodiment
Below in conjunction with drawings and Examples, describe technical scheme of the present invention in detail.
in television set Chinese character input method of the present invention, at first the key assignments with digital keys in television set is associated with the form of phonetic alphabet with the T9 layout, create again dictionary, the key assignments table of comparisons that comprises digital keys and digital keys group, and the mapping table between each key assignments and each effective phonetic in this table of comparisons, effective phonetic is associated with Chinese character in dictionary, in use, the user sends the key of digital keys in order by remote controller, television set will receive the key of digital keys in order, parsing obtains the key assignments of digital keys group, key assignments according to the digital keys group, with the key assignments of each digital keys in the digital keys group in order as the keyword search key assignments table of comparisons, the key assignments that draws according to the key assignments table of comparisons obtains corresponding effectively phonetic from mapping table and the Chinese character that is associated is presented on screen and is selected by the user.
Embodiment
in this routine television set Chinese character input method, at first the key assignments with digital keys in television set is associated with the form of phonetic alphabet with the T9 layout, create again dictionary, the key assignments table of comparisons that comprises digital keys and digital keys group, and the mapping table between each key assignments and each effective phonetic in this table of comparisons, effective phonetic is associated with Chinese character in dictionary, in use, the user sends the key of digital keys in order by remote controller, television set will receive the key of digital keys in order, parsing obtains the key assignments of digital keys group, key assignments according to the digital keys group, with the key assignments of each digital keys in the digital keys group in order as the keyword search table of comparisons, the key assignments that draws according to the table of comparisons obtains corresponding effectively phonetic from mapping table and the Chinese character that is associated is presented on screen and is selected by the user.
Wherein, the key assignments table of comparisons in dictionary is the tree-shaped hierarchical structure of 6 layers, the foundation of classification is the numerical key of input, according to the number of numerical key, belong to different levels, 6 layers is maximum Chinese character spelling number. according to the layout of T9 letter on numerical key, the first floor of most critical with numerical key as keyword, be divided into 8 classes, namely 2,3,4,5,6,7,8,9, other follow-up level is drafted according to the Macintosh principle of legal phonetic; In the key assignments table of comparisons, each node has trackability, refer to that in the structure of dictionary, any one node can find corresponding father node according to the order of successively decreasing, specifically refer to the difference that all effective digital keys in spelling input method make up according to first key assignments is divided into directory tree of 8 classes formation, as shown in Figure 1.Need to prove that the significant digits key combination here refers to that the letter group that its key-value pair is answered can be combined into legal phonetic, here 582 be exactly the key assignments of this digital keys combination as: digital keys combination 582() be exactly an effectively combination, 5 corresponding JKL wherein, 8 corresponding TUV, 2 corresponding A BC, the phonetic that triple bond can be spelt according to sequencing has: kua.In above-mentioned directory tree, each leaf node has trackability, as 7426-742-74-7, if middle certain digital keys combination can not be combined into correct Chinese character spelling, we just are considered as phrase with it and treat, as corresponding to top digital keys combination, phonetic: piao-pia-pi-p being arranged, wherein, second pia can not consist of legal phonetic transcriptions of Chinese characters, can be considered the synthetic phrase of pi and a.
Mapping table in dictionary refers to the key assignments of digital keys group and the mapping relations between effective phonetic, in the directory tree that the digital keys classification forms, each node (comprising Zhi Jiedian and leaf node, root node) shines upon one group of effective phonetic, be the relation of one-to-many, as the mapping relations of the hierarchical relationship of showing in Fig. 1: 5-58-582-5826-58264 and phonetic be:
5→“k”、“l”、“j”；
58→“ju”、“ku”、“lu”、“lv”；
582→“kua”、“jua”、“lua”、“jub”、“juc”、“kub”、“kuc”、“lub”、“luc”、“lvb”、“lvc”；
