SUMMARY OF THE INVENTION The present invention is directed to a method and related media device for use in a media device, and more particularly to a method and associated media device that enables instant segmentation during recording. P Media that can record static and/or motion pictures as multimedia standards has been widely used in modern information society; such as video discs, hard discs or memory cards, digital cameras, digital video recording Like ((3) life), computer with image capture lens, tablet computer, ^ computer, mobile phone, personal digital assistant (pDA, pers〇 second hist), video ageing and driving (4) = Media devices such as recorded screens, monitors, TV systems, TV cards, and 2 computers have become very popular and become part of the second. On the 'Stone T', when using the multi-body case, if the content of the case has been used in the same early section, it will not be very helpful to play, edit, use and slap the multimedia file. In the multimedia file, α and / or manage the different segments in the file quickly (allowing the user (viewer) to take a time-consuming linear search. (Different chapters) jump, no need to enter the chapter segmentation, the user term in the sandal =::: The case is carried out «The chapter is set during playback. This type of post-production === makes 2 201251450

i w /^yAMY is not convenient for the user. SUMMARY OF THE INVENTION In fact, in many applications, when recording a multimedia file, the user also monitors the recorded content at the same time; if the chapter segmentation can be performed immediately while recording the file, not only can the time consuming be avoided The work is also more in line with the user's intuition, and can be segmented immediately according to the current judgment of the user when recording the file. SUMMARY OF THE INVENTION The present invention is directed to a technique for enabling chapter segmentation in real time while recording. It is an object of the present invention to provide a method for applying to a media device that can record a multimedia file containing a plurality of frames. The method includes: when the media device records a file, after receiving a chapter segmentation command, selecting a marker frame in the file, and recording a corresponding chapter information for the marker frame; in an embodiment, This marker frame is the first frame of a chapter. In one embodiment, an intra-frame coding frame that is closest in time is selected as a marker frame after the chapter segmentation command. In another embodiment, after receiving the chapter segmentation command, the media device causes the media device to record a frame encoded frame in the file as the marker frame. The chapter segmentation command can be triggered by the user. The chapter information of the marker frame is used to locate the marker frame in the file so that when the multimedia file is played, it can jump to the marker frame to continue playing. The following examples are given when setting chapter information. In one embodiment, the media device records each frame in the file in units of bytes in sequence from a starting byte; according to the marking frame, the bit group is relative to the starting bit 201251450. The order of the / group can provide corresponding chapter information for each marker frame. In one embodiment, the media device records each frame in the file in units of bytes in sequence after a header by a first byte; according to the tag frame, the byte is relative to the first The order of a tuple provides chapter information for the marker frame. In an embodiment, when the second chapter segmentation command is received when the file is recorded, a second marker frame is selected in the file, and the second marker frame byte is relative to the marker. The order of the frame tuples can provide and record a corresponding second chapter information for the second marker frame. In one embodiment, the corresponding chapter information can be provided according to the time point of the marked frame. In one embodiment, a corresponding second chapter information is provided and recorded for the second marker frame according to the difference between the second marker frame time point and the marker frame time point. In one embodiment, the multimedia file includes a header; during the recording of the file, once the chapter segmentation command is received and the chapter information is set, the chapter information is recorded in the header. In one embodiment, the chapter information is recorded (temporarily) in a memory; when the media device finishes recording the file (for example, after adding a frame to the file), the chapter information is written to the file. In conjunction with the chapters added during multimedia file recording, when playing a file, a chapter name can be displayed according to each chapter information. And/or, a thumbnail of the frame corresponding to each chapter information can be displayed when the file is played. When playing the file, you can jump to the frame corresponding to each chapter information and continue playing after receiving a jump command. It is still another object of the present invention to provide a media device comprising a recording module and a chapter setting module for implementing the method of the present invention. Recording module Record multimedia files; when the recording module records files, if the chapter is set 201251450

The i w/waMY module receives a chapter segmentation command to select the closest intra-frame code frame as the basis for the chapter information. Alternatively, when the chapter setting module receives a chapter segmentation command, the recording module can record a frame code frame and use the frame code frame as the basis of the chapter information. In one embodiment, during the recording of the multimedia file, each time the chapter setting module provides a chapter information, the recording module records the chapter information to the file. In another embodiment, during the multimedia file recording, the chapter setting module temporarily stores the chapter information in the memory; when the recording module finishes the file recording, the chapter information temporarily stored in the memory is recorded into the file. In order to better understand the above and other aspects of the present invention, the following detailed description of the preferred embodiments, together with the accompanying drawings, will be described in detail as follows: [Embodiment] Please refer to Figure 1, which is based on The process 100 of an embodiment of the present invention; the process 100 can be applied to a media device having a multimedia file recording function to implement the function of instant chapter segmentation during recording. The steps of the process 100 can be explained as follows. Step 102: Start recording, and the media device starts to record the frame in a file. Step 104: Detect whether one of the end video command or the chapter segmentation command is received. If the chapter segmentation command is received, proceed to step 106; if the end video command is received, proceed to step 110. If the end video command and the chapter segment command are not received, the detection is continued in step 104. Step 106: If the chapter segmentation command is received, proceed to step 108. Step 108: In the file being recorded, select one in time and chapter 201251450

The 1 w /o^^kaMY section segment command is the closest in-frame code frame as a marker frame, and a corresponding chapter information is set for this marker frame, and the chapter information is recorded in the file. This marker frame also becomes the first frame of a new chapter; its corresponding chapter information is used to locate this marker frame in the file. When you want to play this file, you can skip to this mark frame and continue playing after receiving the jump command. In one embodiment, when the media device records the multimedia file, a header is created at the beginning of the file, and a header field may be included in the header for recording chapter information. Step 108 is to write the chapter information to the directory section in the file header while the file continues to be recorded. Step 110: If the end video command is received, proceed to step 112. Step 112: End the recording. End the recording of the multimedia file and no longer continue to record the frame in the file. Modern media devices compress frames as they are recorded, for example, frame compression in accordance with various version specifications of MPEG (Moving Picture Expert Group). Some frames are compressed by inter-frame coding (predictive coding) or bidirectional coding; such coding compression refers to other frames. Therefore, when playing such a frame, you need to refer to other frames to decompress. To use this type of frame as the first frame of a chapter, it takes some time to jump to this section to complete the decompression of this frame based on the other frames. In order to make the jump of the chapter smoother, step 108 of the process 100 is to select the intra-frame coded frame that is closest in time after selecting the chapter segmentation command as the first frame of the new chapter. Because the frame is encoded in the compression box 6 201251450

J W7825PAMY does not refer to other frames. Once you want to jump to a chapter during playback, the first frame of the chapter can be quickly decompressed and played. However, in another embodiment ten, the present invention may still select a frame that is not in-frame coded (e.g., an inter-frame coded frame or a bi-directionally coded frame) as the first frame of the chapter. The execution of the process 100 can be illustrated by the second figure. The second illustration is an example of the process performed when recording a file 50 (e.g., a multimedia file). The file 50 has a file header 52; with the continuous recording of the file 50, the slot head 52 is sequentially added to the data of each frame, such as frames F(il), F(i), F(i + l) and F(j). ), F(j + l), and so on. Among them, the frames marked with the symbol "X", such as frames F(il), F(i), and F(j), are not in-frame encoded frames. For example, these frames may be inter-frame encoded frames. . In contrast, the frames labeled F(i + 1) and F(j + 1) marked with the symbol "丨" are the in-frame coded frames. At the time of recording the file 5, it is assumed that at the time point tl % • the user triggers a chapter segmentation command Cmdc(n); although the time frame 11 is followed by the frame F(i), the frame F(i) is not In-frame coding frame. After the time point ti, the in-frame coded frame closest to the time point t1 in time is the frame F(i + 1). Therefore, the frame F(i + 1) can be selected as the first frame of the new chapter, and the related chapter information inf〇c(n) is recorded to the header 52. At time point t2, a chapter segmentation command cmdC(n+1) is received again, and the first in-frame coding frame F(j. + 1) after the time point 1:2 can be used as another chapter. The first frame, its corresponding chapter information inf〇c(n+1) is also written to the file header 52.曰 Some media devices compress and record in-frame coded frames in the file periodically and periodically during the recording of multimedia projects; Flow 1〇〇 201251450

I W/WAIVlY can be applied to such media devices because such media devices can periodically provide in-frame coded frames as candidate frames for new chapters. For example, a media device that pays more attention to the image quality of the recorded file will periodically record the in-frame coded frame. Since the in-frame coded frame will appear periodically in the archive, no matter when the chapter segmentation command is received, an in-frame coded frame will appear as the first frame of the new chapter soon after the chapter segmentation command. In an embodiment, the first frame of each chapter has a corresponding chapter information, and each chapter information locates a first frame of the corresponding chapter in the multimedia file, so that when the file is played, it can jump to The first frame of each chapter continues to play. Please refer to FIG. 3, which is a schematic diagram of positioning each chapter frame according to an embodiment of the present invention. When the media device records a multimedia file 50, it can record the file 50 in units of bytes. As shown in Figure 3, the file 50 records the floor 52 in bytes B(1), B(2) through B(Nh) in the sequence of bytes, with bytes B (Nh+l) to B. (Nh+N(l)) records the first frame F(l), and records the i-th frame with the byte B (Nh+N(il) + l) to B(Nh+N(i)) F(i) (where i is greater than 1), and so on. However, the present invention can set chapter information for the mark frame of each chapter (i.e., the first frame of each chapter) according to the order (or address) of the byte. In one embodiment, since the byte B(l) is the starting byte of the entire file 50, the chapter information can be set in accordance with the order of the respective tag frame bytes relative to the byte B(1). For example, suppose the first frame of the first chapter is the frame F(i + 1), because its first byte is B(Nh+N(i) + l), so it can be followed. The sequence (Nh+N(i) + 1) is used to record the chapter information corresponding to this chapter. Similarly, if the first graph 201251450 1 W/δ^ΡΑΜΥ box of the second chapter is F(j + 1), since its first byte is B(Nh+N(j) + 1), In this way, the chapter information can be recorded for this second chapter according to the order (Nh+N(j) + 1), and so on. In another embodiment, since the file 50 is recorded by the first byte B (Nh+l) after the file header 52, the frames in the file are sequentially recorded in units of bytes, so that each mark can be used according to each mark. The frame bins are positioned relative to the first byte > to locate the first frame of each chapter. For the first frame F(i + 1) of the first chapter, since its first byte B (Nh+N(i)+1) is the first after the head 52 (N(i) + 1) a byte, so the chapter information can be defined according to its order (N(i)+1); for the first frame F(j + 1) of the second chapter, it can be based on the order (N(j) ) + 1) Set the chapter information. In another embodiment, 'when providing a corresponding chapter information for a current marker frame', a chapter may be defined for the current marker frame according to the relative order between the current marker frame byte and the previous marker frame byte. News. For example, 'for the first frame of the first chapter F(i + 1), according to the order of its first byte B (Nh+N(iHi) (Nh+N(i) + 1) Define its chapter information; for the first frame F(j + 1) of the second chapter, due to the first byte B of the frame F(j + 1) (Nh+N(j) + l) Is the (N(j)-N(i)) byte after the byte B (Nh+N(i) + l), so the chapter of the second chapter can be set according to the order (NQtNQ)) News. In other words, suppose the first frame of the kth chapter is the frame F(kl + 1) (the first byte is the byte B (Nh+N(kl)+l)), The first frame of the (k+Ι) chapter is the frame F(k2+1) (the first byte is the byte B (Nh+N(k2) + l)), then the bit is based on the bit The relative order difference (N(k2)-N(kl)) between group B(Nh+N(kl)+l) and byte B(Nh+N(k2)+l) is the (k+i) ) chapter setting chapter 201251450

1 W/5ZDi" AlVlY information. When playing file 50, to jump from the kth chapter to the (k+Ι) chapter, just add the k-th chapter of the early section information to the section information of the (k+i)th chapter. The first frame of the (k+1)th chapter can be located and played back by the frame. In another embodiment, for the first frame F(i+Ι) of the first chapter, its chapter is defined according to the order of its first byte after the header 52 (N(i)+1). Information; for the first frame F(j + i) of the second chapter, the chapter information is set according to the relative order (N(j)-N(i)). That is, suppose the marker frame of the kth chapter is the frame F(kHl) (the first byte of which is the byte B (Nh+N(kl) + l)), the first (k+Ι) The flag frame of each chapter is frame F(k2+1) (the first byte is byte B (Nh+N(k2)+l)), then according to byte B (Nh+N) (k2) + l) Set chapter information for the (k+Ι)th chapter relative to the order of the byte B (Nh+N(kl) + l) (N(k2)-N(kl)). In the embodiment of Fig. 3, the number of bytes occupied by each frame may be different. The first byte of each frame (such as the byte B (Nh+N(il) + l) in frame F(i)) can be the frame header of each frame; the frame file The content of the header can be a fixed sequence of bits. In the discussion of Figure 3, the byte is taken as an example, but any single (such as a bit or a character group, etc.) that can properly divide the file 50 can be used to define the chapter information. Please refer to FIG. 4, which is a schematic diagram of positioning each chapter frame according to an embodiment of the present invention. In this embodiment, when the media device is recording the multimedia file 50, it is at time points t(l), t(2), ..., t(1), ΐ(Ηΐ), ..., respectively. "With + frame FO", 201251450

1 W / 525KAMY can provide the corresponding chapters in the first frame according to the time of the first frame of the blood, and the first frame F(i + 1) for the first chapter can be based on The time point t(i + l) (for example, the difference between the time point (1) and the seven (1)) is used to set the chapter information of the i-th chapter. For the first graph of the second chapter, busy F(j + i), the second chapter is set according to the time point t(j + 1) (for example, the difference between the time point +1) and t(1)) Chapter information, and so on. In another example, when you want to set chapter information for a chapter, you can refer to the difference between the time point of the chapter marker frame and the time point of the previous chapter marker frame. For example, when setting the chapter information of the second chapter, the difference can be defined according to the difference between the time point t(j + 1) and the time point t(i + 1) "(ΗΙ) t(i + l)) Chapter chapter information of two chapters. That is to say, if the marker frame of the kth chapter is the frame F(kl) (corresponding to the time point Wkl), the marker frame of the (k+Ι)th chapter is the frame. F(k2) (corresponding to time point t(k2))' is the (k+i) according to the time point difference between frame F(k2) and F(klws) (t(k2)-t(kl)) Chapters set chapter information. Some media devices can record frames with a fixed frame rate, so if the time point corresponding to a frame is known, the frame can be located in the multimedia file.
