INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to data error correction, and more particularly to a method and apparatus for detecting image data errors. - [Prior Art] _ It is difficult to avoid data loss during the process of storing, reading and transmitting image data. For example, during the reading of image data from a disc, certain frame image data (such as I-frame, B-channel) may not be read due to factors such as the quality of the disc reading member or the disc. Box or P frame), and then V is lost. The loss of frame image data will have a relatively serious effect on the image playback effect, for example, the program can only be played intermittently. If the previous technology can detect the loss of the frame image data, it can refer to the corresponding lean = to recover the lost frame image data. For example, if the b-frame or (4) frame image data is lost, the image data can be restored to some extent by referring to the corresponding I-frame image data, so that the image data can be restored to a certain extent. Play the program on the disc. In the prior art, the technical solution for detecting the loss of frame image data is generally constructed based on the type sequence of the frame image data. Image: The material contains a plurality of screen groups G〇p, and a G〇p includes a certain amount of frame images. Each frame image data is decoded according to a type sequence (eg, work, such as I B, B, p, etc.) or used for image display and the like. The type of frame image data processed by the two custodians should be processed. If the type of the hole frame ~ like the material of the beaker is inconsistent, it can be judged that the image I has a wrong 'that is, 'the frame image data is lost. For example, at time 116739.doc 200823801, 'B-frames should be processed, but the actual drop-down's can't be smashed, and the p-frame will be processed, then it can be judged that the image is poor. The frame image data is lost.
采用别述解决方案之兩提為··各別G〇p具有統一且規則 之資料結構，使得每-訊框影像f料可以_固定類型序列 來解碼或顯示。然@，即使共同節目場景轉換將導致GOP 之各別訊框影像類型序狀變化，⑽p中訊框影像資料之 f理序列亦總是可變的。因此，此解決方案不能滿足影像 貝料之錯誤摘測及校正的需求及判定丢失訊框之量。 :因此，需要提供-種偵測影像資料錯誤以债測在影像資 料中是否存在訊框影像資料丟失及丟失資料之量之方法。 法用於〜像、料之錯誤校正且可有效地恢復丢失資料 並改良播放效果。 、 【發明内容】The two solutions mentioned above are different. Each G〇p has a uniform and regular data structure, so that each frame image can be decoded or displayed in a fixed-type sequence. However, even if the common program scene transition will result in a sequential change in the image type of the GOP frame, the sequence of the (10)p frame image data is always variable. Therefore, this solution cannot meet the requirements of error sampling and correction of image materials and determine the amount of lost frames. : Therefore, it is necessary to provide a method for detecting image data errors to determine whether there is a loss of frame image data and the amount of lost data in the image data. The method is used for error correction of image and material, and can effectively recover lost data and improve playback performance. [Content of the invention]

For example, in the technical standard of ancient mu-ray disc BD, 72 () x 576 per second, 25 frames of image sequence (four) code rate is about 5 Mbps, and each (four) frame image data includes ^ 42.8, material package, each —P frame image data includes (4) data sealing and mother-B frame image data including 68 4 data packages. Generally speaking, the head information of each data package contains the processing sequence information of the frame image data. The processing sequence includes a decoding timestamp DTS of the decoding time series of the pure material, which may also include - a presentation time stamp ρτ§ for determining the presentation time series of the frame image, and the like. Next, the difference between the processing sequence information of the two frame image data is determined (step S120). The difference between the processing sequence information of the two frame image data (such as decoding time information) may be the difference between the decoding sequence time or the difference between the presentation time times, and if the data is read from the optical disk, This may include differences between memory address information and the like. Generally, the decoding time stamp DTS of the frame image data is determined according to the face synchronization time stamp PSTS, and the pSTS is locked according to the program clock reference, so the DTSi of the i-th frame image data can be locked by PSTS^ indicates. 116739.doc 200823801 As shown in equation (1), the decoding timestamp DTSi of the frame image is equal to the reference offset Td on PSTSA. Td is associated with the reference clock of the decanter and is a fixed value. DTSi-PSTSi+Ta (1) Correspondingly, the decoding time stamp difference of two consecutive adjacent frame images is expressed as equation (2). ADTS. = DTS. - DTSh] = PSTS, - PSTSM (2) Next, the processed sequence difference is compared with a reference value (step s13). In a particular image data format, the DTS difference PSTSrPSTSi· between two consecutive consecutive frame images is only associated with the image format. For an image format, PSTSrPSTSM is a fixed value F. This reference value can be set to a fixed value F. The numerical relationship between PSTSrPSTSi and #F can be obtained by comparison. For example, PSTSrPSTSM=F, or PSTSrPSTSM>F, or PSTSi-PSTSi-^nF, F's n (n is an integer greater than 丨) times, and so on. Next, based on the comparison result, it is judged whether there is data loss between the two frame image data (step S140). If PSTSi-PSTSi-pF, it can be judged that there is no frame image data loss between the two frame image data, that is, the two frame image data are continuous. Right PSTSrPSTSM>F, it is judged that there is frame image data loss between the two frames of image data, that is, the detected image data has a data error. In addition, if PSTSrPSTSM=iiF (n is an integer greater than 1), it can be determined that there are (n_1} frame image data 116739.doc 200823801 between the two frame image data. Finally, if there is a frame The image data is lost by a positive method to recover (4) the frame of the lost frame image 22: complex or school, can be estimated by the motion vector method = in the previous technology set #胄μ ^ > test the adjacent frame image in a The image right method provided by the present invention includes the step m recovery and correction steps of the method for measuring image data.

For an image format, the processing sequence difference between the two frame image poor materials is a fixed value F, The two pivoting image data are successively adjacent in the processing sequence, so F can be taken as a reference value to compare with the processing sequence of the two adjacent frame image data in the processed image data. The corresponding relationship between pSTS^pSTSM and F is obtained after comparison. For example, psTSi_pSTSi i=]p, ρπ, PSTSbPF, or PSTSi-PSTSi.mF, F of n (n is an integer and n>1) times and many more. " component 210 further includes a decision component 214〇 for determining whether there is a frame image data loss between the two frame image data based on the component 丄i 3u ratio flat parent result. ^^TSrPSTSf F, it can be determined that there is no frame image data loss between the two frames of image data, that is, the two frame image data are continuous.

In addition, if the PSTSrPSTS produces nF, it can be judged that there is a loss of (frame) image data between the two framed image materials.
