The mpeg format data is the data behind a kind of compressed encoding, it includes three kinds of different compressing images (frames), be respectively I picture, P picture (Predicted frame) and B picture (Bi-directionalframe), the I picture is the whole image frame of compression, the similar JPEG compression of this compression method, utilize the mathematical operation of discrete cosine transform (DCT, Discrete Cosine Transform), quantization (Quantization) and huffman coding method (Huffman Encoding) to handle unnecessary data irrelevant and that repeat; The P picture be I picture with the front as the reference image, have the part of repetition just to store in the picture, only record stores two different parts of picture, the part of this difference promptly is called the P picture; The B picture is because of above-mentioned every picture to be done same action, some mistakes may take place in this along with the time, because these mistakes are to accumulate, so can insert the mode that a picture is compared the front and back picture frequently again, the B picture is exactly that so the difference of B picture and P picture is that the B picture can be with reference to the I picture and the P picture of front and back, in these three kinds of squeezeds, the data quantity minimum of B picture, P picture maximum, these three kinds of pictures do not have certain arrangement order.
The data of picture reduced needed data total amount of specific picture of demonstration before and after P picture and B picture were used, so they are temporary compression datas, it is not complete information, thereby decompress(ion) shows separately, and the I picture is because compress a complete picture, so decompress(ion) shows separately.Hence one can see that, and the I picture is a reference picture, P picture subsequently and B picture all can be referenced to its data, so the mpeg format data is when playing, but must find just playing video of I picture earlier,, change when stopping and the user is fast so work as the mpeg format data in broadcast, its position of stopping is not as being just when the I picture, playout software just must be sought the I picture forward with the playing video data, so behind fast the commentaries on classics, the broadcast of image can produce delay phenomenon.In addition, when imprinting mpeg format data, computer system must be sought the position of each I picture of record, carries out imprinting afterwards again, so the user can find when imprinting MPEG image data necessary one previous operations period of wait.
The present invention is when storing audiovisual materials, be to set up concordance list, with each the I picture position in the mpeg format data of record storage, so direct imprinting concordance list in the process of imprinting, and needn't seek record I picture position again, shortening the imprinting time, and can improve at the fast smooth degree of back when playing that change.In addition, when storing audiovisual materials tostorage element 45, computer system can be opened a save File instorage element 45, when computer system download storage audiovisual materials reach one section appropriate time or data size, computer system can be opened another save File, and audiovisual materials are continued to be stored in the new save File again, so till download has stored audiovisual materials, the big I of save File storage time and data is set in computer system by the user, this method stores into audiovisual materials the save File of set time or data size, user's imprinting is stored in the discs after can making things convenient for, in order to carrying preservation.
