[Prior Art] In recent years, 'video devices' such as Video Cassette Recorder (VCR) and Digital Versatile Disc (DVD) video recorders have been widely used in recording movies and video programs. These recording and playback devices can read data from a storage medium and display still pictures or dynamic pictures on a screen, and play corresponding audio data; in addition, 'multiple dynamic pictures and related audio materials can also be recorded. On the storage medium. A typical hard disk recorder, such as a Digital Video Recorder (DVR) or a Personal Video Recorder (PVR), has a so-called Time Shift function called 'Time Shifting'. The function is that the user can watch the live TV program on the hard disk recorder, and when he has to leave the middle, just press the pause button to pause the program. 'The viewer can leave to do what he wants to do; during the user's departure, The hard disk video player will still play the live directory of the festival. 'When the user returns to the front of the screen, press the play button, then you can watch it without missing any clips, just like watching a videotape. Move the current moment to the next point in time to send 1337402, which is one of the most attractive features of the hard disk recorder. In general, the video function is divided into several video modes, including: High Picture Quality Play (XP), Standard Play (SP), Long Play mode (Long piay, Lp), and special dialing Release mode (ExtraL0ngPlay, EP), etc. Different video modes correspond to different encoding bit rate (eneoding bit rate) 'If the most bit rate of these video modes k is ranked to the lowest bit rate, then the order is high book mode. , standard mode, long play mode and extra long play mode. As can be seen from the above, the still mode has the highest coding bit rate, while the extra long mode has the lowest coding bit rate. Since the quality of the image encoding is proportional to the encoding bit rate, it has the best image quality in the high quality mode and the worst image quality in the special mode. Although the high-quality mode has the best quality, but its high bit rate produces a large coded image position, thus reducing the number of other image bit streams that can be recorded on a storage medium (such as f or DVD); Although H has the worst image quality, the low bit rate produces a small stream of imagery bitstreams, thus increasing the number of image bitstreams on other recordable media. In view of this two: sub-I::::: video mode to achieve the most efficient storage media == important issues of the Cheng Ma video system.丨文1337042 [Draft] The patent application scope of the present invention discloses a method for recording media data, which comprises the following steps: (a) a first: encoding bit rate in a first time interval Recording a first part of the media data to a storage medium; (b) determining whether the first time interval is greater than a specific time; and (c) determining whether step (a) is based on the judgment result of step (b) The first portion of the media data stored in the storage medium is transcoded into a second encoding bit rate by the first encoding bit rate. The patent application scope of the present invention discloses a recording system for recordable media data, comprising a media data input end for receiving a media data; an encoder/decoder coupled to the media data input end, the encoding/decoding The device is configured to record a first portion of the media data at a first encoding bit rate; a storage medium coupled to the encoding/decoder for storing the first portion processed by the encoding/decoder And a determining device coupled to the storage medium and determining whether the amount of data of the first portion of data stored in the storage medium is greater than a threshold value; and a control device coupled to the encoder/decoder and the The judging device controls whether the encoder/decoder changes the first part of the data stored in the storage medium to be recorded at a second encoding bit rate according to the judgment result of one of the judging devices. 1337042 [Embodiment] Please refer to FIG. 1 'FIG. 1 is a functional block diagram of a video recording system 10 for recording media data according to the present invention. The media data refers to an object that needs to be carried by a media to carry a message. The media data can be text, video (graphics, video, etc.), audio (music, language, sound) and other materials; and the media for playing media data can be projectors, slide projectors, video recorders, tape recorders, televisions, radios, computers. Play media such as the Internet. The video system 10 can be a digital video recorder (DVR) or a personal video recorder (PVR). The video system 10 includes a media data input terminal 12 for receiving a media data, for example, receiving a wired or wireless television broadcast signal, etc., an encoder/decoder: (codec) coupled to the media data input terminal ,2, The multimedia material is encoded or decoded, for example, the encoder/decoder 14 is configured to record the first-part data of the multimedia material at a first rate, and the buffer media 16 coupled to the encoder/decoder #^14 Used to store encoded/disc machines.铮 , , , , , 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存 储存The first part of the data is stored to learn that the storage medium 16 system 10 further includes - control, : 里 - no greater than the threshold value, video judgment result, control code, 7 to _ break device 18 - horse Μ疋No to record the first part of the data stored in the storage medium 16 1337042 . * by a second encoding bit rate. Please refer to FIG. 2, which is a flow chart of the media data recorded by the video recording system 10. The method includes the following steps: Step 100: The video system 10 uses a first code in a first time interval. The first bit of the media data is recorded to the storage medium 16 by an encoding bit rate. Step 102: The determining device 18 determines whether the first time interval is greater than a specific time. When it is determined that the first time interval is greater than the specific time, step 104 is performed; otherwise, step 108 is performed. Step 104: The control device 20 controls the encoder/decoder 14 to transcode the first portion of the data stored in the storage medium 16 into a second encoding bit rate. Step 106: • The video system 10 continues to record the second part of the media data after the first time interval at the first coded bit rate or the second coded bit rate, or other coded bit rate. In the first part of the data) to the storage medium 16. Step 108: The video system 10 continues to record the second portion of the media data to the storage medium 16 at the first encoding bit rate, and does not perform transcoding on the first portion of the data stored in the storage medium 16. . ' Step 110: End. 9 042 Here is a detailed description of the above steps. For example, if the storage medium 16 is a DVD disc or a hard disk drive with a storage capacity of 5 GB, in the normal recording state, if the data stream is a high book quality of 9 Mbps. In the mode (j^gh Picture Quality, XP), media data can be recorded for 1 hour and 2 minutes; if the data stream is 6 Mbps (Standard piay, sp), media data can be recorded for 2 hours; The media stream can be recorded for about 4 hours in the long play mode (Live play, LP) with data stream, and if the data stream is 1.5 1^5, the special long play mode (£加1^called Play, EP) The media data can be recorded for about 8 hours, which means that the resolution of the image quality is from high to low, high quality mode, standard mode ^, long play mode, and special (4) Lai. When recording media 1 () media resources: the input U receives the corpus data] and set the [mode to record the media ^ == coder will be in the corresponding mode of the horoscope bit rate ~ media Bell Encoding, and encoding the #_存体', so the user can first set the recording system 1() to (for example, within 2 hours) to correspond to the mode (such as the standard phantom 2': bit rate Recording the first part of the media data to the storage media room == judgment = time exceeds the specific special =: 2 hours), then represents the next storage medium:: foot, the storage space is stored in standard mode The recorded media ^ sister, there is 'ί especially said that the judging device 18 judges that the storage medium 16 is stored in the Guangbei 4, and the data amount of the data encoded by the device 14 is about to be greater than a Linzi ^, 'i bat / decoding must be reduced The video quality is exchanged for a larger media storage value, the leaf storage space, and the control device 1370402 set 20 will control the code/decoder 14 to store the first data stored in the storage medium 16 from the first encoding bit. Rate transcoding into the second encoding bit rate, wherein the second encoding bit rate is less than the a coded bit rate, wherein the first coded bit rate corresponds to a first resolution, the second coded 1-bit rate corresponds to a second resolution, and the second resolution is less than The first resolution. The first coded bit rate may correspond to a coded bit rate of a high quality mode, a standard mode, or a long play mode, and the second coded bit rate may correspond to a standard mode and a long play mode. Or the encoding bit rate of the special long-play mode. For example, the first portion of the media data that has been previously recorded in the storage medium 16 can be transcoded into a lower image encoding quality by a higher image encoding quality (eg, high quality mode, standard mode, long play mode, etc.) (eg, The mode of standard mode, long play mode, extra long play mode, etc., to free up more storage media 16 storage space to record subsequent media materials. The video system 10 may continue to record the second portion of the media material to the storage medium 16 after the specific time. The first encoding bit rate or the second encoding bit rate' or other encoding bit rate. On the other hand, if the judging device 18 judges that the recording time does not exceed the specific time, the recording system 1 can continue to record the second portion of the media information to the storage medium 16 at the first encoding bit rate, and The data stored in the storage medium 16 is transcoded. Please refer to FIG. 3, which is a schematic diagram of the video system _10 adopting different video recording modes at different overall recording times according to the first embodiment of the present invention. It can be seen from the figure of 13 1337042 3 that when the overall recording time is less than 2 hours, the video system 10 can completely record the media data to the storage medium 16 under the standard mode, so that the standard mode video can be used in the whole process; The time is more than 2 hours but: When it is less than 4 hours, the video system in standard mode cannot record completely. The media data is stored in the storage medium 16, so the previously recorded media data (0 - 2 hours) can be correspondingly matched. The coded bit rate of the standard mode is transcoded to the coded bit rate of the corresponding long play mode, and the media data is recorded in the long play mode 0 after 2 hours, so that the media data adopts the coded bit corresponding to the long play mode. When the overall recording time exceeds 4 hours but is less than 6 hours, the recording system 10 cannot record the media data to the storage medium 16 in the long play mode, so the previously recorded media data can be transcoded into corresponding The coded bit rate of the extra long dial mode, and the media data is recorded in the special long play mode after 4 hours, so that the media data is all used correspondingly. In the long-distance playback mode, the encoding bit rate is recorded; however, when the overall recording time exceeds 6 hours, the recording system 10 cannot be finished in the special long-play mode. • The media data is completely recorded to the storage medium 16, so the video recording time is deleted at the earliest. The media materials are used to reprint the media materials recorded after 6 hours from the media materials recorded at the beginning. Please refer to FIG. 4 , which is a schematic diagram of the video system 10 according to the second embodiment of the present invention using different video recording modes in different time intervals corresponding to the overall recording time, which is different from the first embodiment, and is in the second embodiment. Zhongcai' uses different video modes to record the overall media data in segments. For example, 12 1337042 When the overall recording time is less than 2 hours, the recording system 10 ^ can record the media data to the storage medium 16 in the standard mode, so the standard mode recording can be used in the whole process; when the overall recording time is more than 2 hours but less than 3 hours, can; convert the previously recorded media data (0-2 hours) from the original encoding bit rate to the encoding bit rate of the corresponding long playing mode, and the standard in the second to third small time The mode continues to record media data; when the overall recording time exceeds 3 hours but is less than 4 hours, the previously recorded media data (0-3 hours) can be transcoded into the corresponding bit rate of the corresponding extra long mode, and From the 3rd to the 4th hour, the media data will continue to be recorded in the standard mode; however, when the overall recording time exceeds 4 hours, the media data with the earliest recording time must be deleted at this time to overwrite the media information recorded after 4 hours. Media materials recorded at the beginning. The feature of this embodiment is that the recently recorded media data can be recorded in a higher image encoding quality recording mode, and the previously recorded media data is recorded in a lower image encoding quality recording mode, so that the latest information can be kept up to date. Better image encoding quality for recorded media data. However, the concept of using different video recording modes in different time intervals of the present invention is not limited to the above-described embodiments, and will not be described in detail herein. Compared with the previous video recording method, the present invention can dynamically adjust the recording mode of the recorded media data or the media data to be recorded according to the length of the recording time, so that the user's needs (image quality requirements or recording time requirements) can be met. By managing the video mode in a limited storage media space to achieve efficient storage media management, it also provides a user-friendly video management mechanism. 13 1337042
