Abstract

The invention is a system and method for setting a self-compressed data in a compressed data stream. The compressed data stream is composed of segments of first group and segments of second group. The segments of first group do not need to be decompressed during the processing, and only the status thereof, like timestamp, needs to be adjusted. The segments of second group need to be decompressed for successive operations. Then a frame of the second group is set to be a self-compressed frame. Next, the resulting segments of first group and second group are combined together to produce a target data stream. Because of decreasing unnecessary decompression and recompression, significant efficiency is obtained and error propagation is reduced during processing the compressed data stream.

Description

588554 V. Description of the invention (1) — > [Technical field to which the invention belongs] The present invention relates to a system and method for setting self-compressed image data to a compressed data stream. 2. [Previous Technology] Whether it is software or hardware, computer technology has made great progress in recent years. In addition to common desktop computers, computer technology has also been continuously extended to home appliances, such as VCD players, MP3 players, etc., making computers and related products more and more versatile and diversified. . One of the most important changes is that computers and related products based on text in the past have evolved to a multimedia age that includes images and sound, whether it is processing content or interfaces. In the multimedia age, whether it is film, teaching course, interactive communication, it involves a huge amount of data. Therefore, whether it is multimedia information storage or transmission, it is necessary to solve the problem of huge data volume processing. Faced with these huge data, one of the main processing methods is to compress the data. For different kinds of information, different compression methods are adopted according to their characteristics. For example, JPEG, GIF, PCF for image, MP3, RAM for audio, MPEG, AVI for video, and ZIP, ARJ, TAR and other compression methods for general data. The compression method can be divided into two categories: lossy compression and non-distortion compression. The previous method used the characteristics of various data to sacrifice a part of the information amount in exchange for a larger compression ratio.

Description of the invention (2) Due to the help of these compression methods, although there is still a bandwidth limitation on the network, there can be video and audio multimedia applications on the network, such as Video On Demand and so on. People have been looking for compression methods that can bring higher compression ratios. However, the higher the compression ratio, the more complicated the compression method. The following is a description of the commonly used distortion compression method MPEG. MPEG is the abbreviation of Moving Picture Experts Group, and stands for a series of international standards, such as MPEG 1, MPEG 2. The current audio and video discs, including VCD and DVD, use MPEG compression technology. MPEG compresses multimedia data of video and audio with different data streams. 0 Please refer to the first figure (A). The first figure (A) shows an example of a multimedia data. The multimedia data 111 includes a video data stream channel 112 and a sound data stream channel 113. When this multimedia data is played, the channels are synchronized through time parameters to provide multimedia broadcasting effects. For the commonly used MPEG data stream, multiple video channels and sound channels can be included in one MPEG data stream, and each channel is compressed separately. Here, the MPEG video stream is used. Give a brief explanation. In the compression method of MPEG video data stream, the intra-view frame is also used.

Description of the invention (3) (intraframe compression) and Interframe compression to achieve the best compression of the data, and the ability to play randomly. First, the intra-frame compression used by the MPPEG compression method is briefly introduced. Video data consists of a series of frames. In order to provide the effect of visual retention, usually 30 frames need to be released in one second. The data compression in the video includes color plane sampling, Discrete Cosine Transform (DCT), numerical sampling, zig-zag, dynamic length compression coding and other steps. Please refer to the first figure (B). Generally, the image data is composed of three color dimensions of red, green and blue (rgB). However, due to the nature of the human eye's change in color, we can use 16 × 16 image points, that is, a macro block, as a unit to map the RGB plane into a photometric plane Y. (luminance plane) is equipped with two chrominance planes u and V (chrominance planes), and the matching ratio can be 4: 1: 1 (step 1 2 1). In this way, the amount of data is reduced in the first step. Please refer to the first figure (B). Next, using the 8 × 8 image points, that is, a block as an early bit, perform the matrix transformation operation of the discrete cosine function (DCT) on the sampled γ, | j, and v plane data (step 1 2 2) . Then, the transformed matrix data is sampled and quantized (Quantization). At this time, different scale quantization can be performed according to different quality requirements (step 123).

Page 8 588554 V. Description of the invention After completing the above-mentioned transformation and sampling and quantization of each block, the two-dimensional image in the block is displayed in a zig-zig correspondence manner, as shown in the first figure (c). The point lean is represented by a one-dimensional sequence. Next, the one-dimensional sequence is subjected to dynamic length reduction coding, such as Huffman coding (jj u f f m a n c n d d n g) (step 124). In addition to the intra-frame distortion compression described in Θ, since video data often has considerable similarity between frames, MPEG uses inter-frame compression to achieve a larger compression ratio. Please refer to the first figure (D). A view frame can be regarded as a combination of many blocks, and each block is composed of certain pixels, such as 8 × 8 pixels. For the N frame 1 3 1 to be coded, search for the images in each box in sequence ν-1 with reference to the frame 1 3 2 to find similar information. For block 1 33 in ν view frame 1 31, if it can be expressed to some extent as an antipodal N — ι reference block 134 in view frame 132, then block 丨 33 only needs to use the motion vector 135 as the encoding data Instead of encoding with the original color data. For video data that often has a considerable correlation between frames, such a compression method, although it will cause distortion, can provide a considerable compression ratio. In the first picture (D), the frame N to be coded is encoded with reference to the previous frame N-1. At this time, the frame N is referred to as a P frame. In addition to the ρ frame, in MPEG, there are other I frames that do not reference other frames, and B frames that refer to the front and rear frames. Please refer to the first picture (E), which illustrates a video sequence in an MPEG video data stream, which is composed of different {, P, B video frames in a certain order.

However, through the above-mentioned compression and compression, the compressed data in the video frame and the compressed data in the video frame are combined with the material stream, such as the first, to form MPeg data codes in the form of packets, so M ^ does not . Since the MPEG data stream takes a dynamic length. The playback or editing process may depend on the combination of different packet numbers.

In order to solve the huge amount of multimedia data, we must adopt complex coding like MPEG to reduce the storage and transmission of data. However, when we want to deal with such compressed data streams, such as DVD-type MPEG data streams Paragraph marks have been added to it, but many complex questions have been raised ^. Because in this type of compressed data stream, all frames except the self-compressed frames need to be referenced to the nearest self-compressed frame for compression. Therefore, when adding a paragraph mark, if the specified frame is not a self-compressing frame, such as the B frame or P frame in the first picture (E), the starting point of this paragraph will be automatically changed to the specified position. Self-dancing, contraction that is closest to the specified frame

However, this method causes this paragraph to fail to accurately use the set view frame as the starting point. To solve this problem, you can only adjust the frame to be set as a paragraph mark, and t compress the frame. However, this requires decompression of all compressed data streams and recompression after adjustment. For compression methods like MPEG, the process of compression and decompression is often time consuming. In addition, for a distortion compression method that can bring a high compression ratio, if multiple decompression operations are performed after g / compression action, > it is expected that distortion propagation (er r 0 r propagation) will occur. For example, in the compression method of the MpEG video data stream, the compression within the video frame or the video frame is not official. After multiple decompression and recompression operations, each recompression may lose more. With the further part of the information, the information will continue to be lost, which will degrade the quality of the video. 3. Summary of the Invention The main aspect of the present invention is to provide a system and method for setting self-compressed image data to a compressed data stream, so as to improve the efficiency and reduce data errors when setting the self-compressed image data. The main aspect of the present invention is to provide a system and method for setting self-compressed image data to a compressed data stream, for setting a paragraph mark on a predetermined view frame in the compressed data stream.

Description of the invention (7) The system of the first embodiment of the present invention includes a dispatch unit, a first processing unit, a second processing unit, and an integration unit. The dispatch unit distinguishes the source compressed data stream into a first group source section and a second group source section. The first group of source sections is adjusted by the first processing unit to generate the first group of target sections without decompression and recompression. The second processing unit includes a decompression unit, a setting unit, and a recompression unit. The second group source section is first processed by the decompression unit to become the second group source section. Since the source group of the second group is in a decompressed state at this time, one of the image data can be set as the self-compressed image data by the setting unit. After the setting unit is set, an uncompressed second group target segment is generated. This uncompressed second group of target segments is recompressed by a recompression unit to generate a second group of target segments. The first group of target sections and the second group of target sections are merged by the integration unit, and a target compressed data stream is generated to complete the processing operation. The present invention can further set the self-compressed image data as a paragraph mark. Therefore, the image paragraph following this self-compressed image data can accurately use this self-compressed image data as the starting point of the paragraph. Since unnecessary decompression and recompression actions are omitted, the system can effectively save computing time, and at the same time, avoid information distortion caused by the decompression and recompression processes.

The compressed data stream 2 5 is divided into a source group of first gr oup 26 1 and a source group of second group 271 ° according to different needs of processing. The compressed data stream 25 is a compressed ordered data set, and its implementation is, for example, an MPEG compressed video data stream, a DVD video format data stream, and the like. For example, the packet sequence (p a c k e t sequence) of the first figure (E) can be regarded as one MPEG compressed data stream, which includes several MPEG compressed video data streams and MPEG compressed audio data streams. In an embodiment, the second group source section 271 may be located anywhere in the source compressed data stream 25. According to the embodiment shown in the second figure (A), the source group 2 71 of the first group is located in the middle of the source compressed data stream 25. However, in other embodiments, the second group source segment 2 71 may also be located at the head or tail of the source compressed data stream 25. Please refer to the second figure (A). The dispatch unit 21 divides the source compressed data stream 2 5 into a first group source section 2 6 1 and a second group source section 2 71. Next, the dispatch unit 21 delivers the first group source section 2 61 and the second group source section 271 to the first processing unit 22 and the second processing unit 23 for processing, respectively. The first group source section 2 6 1 refers to a part of the source compressed data stream 25 (port i〇n 〇f

Description of the invention (105 source compressed data stream), and the second group source section 271 refers to another part of the source compressed data stream 25 that needs to be decompressed in the processing program. In addition, after the processing by the first processing unit 22 and the second processing unit 23, the processing result of the two is combined by the integration unit 24, and a target compressed data stream 28 is generated. It is possible to adjust the parameters of the first group without adjusting the parameters of the first group (such as stamp), and the first group can be adjusted as shown in the first processing unit 22 of the source area of the first group. It is only necessary to use the MPEG compression-packed video frame, without the need to send compressed data streams such as tags, etc., and more importantly, 'so that propagation can also be avoided.' The group source section 2 6 j is decompressed, so the first processing unit 2 2 only needs to selectively select the status of the source section 2 6 1, such as the time tag (t 丨 me data. The "selective adjustment" mentioned here It indicates the status of the source section 261, and the status of the section 261 may not be adjusted according to circumstances. In addition, after adjusting the status, the first group of target sections 262 are generated, as shown in the second figure (a). For example, for those frames, the state of the packets is not changed. You can adjust the state of the packet according to the situation. For example, the first group of time labels is decompressed before the daytime surface is adjusted. The complex compression method says 'this will save a considerable amount of computing time. This' is for distortion compression methods such as MPEG video data streams to avoid distortion expansion that may occur during recompression (error to maintain the best quality of the data.
