The audio-video contents and program information are received together and programs for watching later are selected according to the received program information without a program guide. Thus recording incompletely and recording unwanted programs, resulting in the asynchronous situation of the audio-video contents and the program guide, will not happen.

Description

1227091 V. Description of the invention (1) 1. [Technical field to which the invention belongs] In particular, no program is used. This invention relates to the program pre-recording system of the South. 2. [Previous Technology] The programs are becoming more and more diversified, and the options are more and more. The time available for watching programs is limited every day. How can I choose the programs I want to watch and the programs I can see at any time? , Become a development focus in the multimedia field. As shown in the first figure, the general program pre-recording mode is to obtain the program information from the program guide 2 by the pre-recording device 10, and then set it in the pre-recording control device 102, and the program is tuned by the tuner 104 at a specific time. The input signal 4 outputs the audio and video of the program to the video recording device 106. The above method can be achieved by a video recorder or a computer system. All relevant information about previous programs is collected in the program guide, including: program name, broadcast time, broadcast channel, and so on. Sometimes it also contains a list of actors and a brief introduction to the show. Obtaining the program guide usually requires users to take the initiative to obtain it, and the methods may be watching, listening, reading, and so on. Therefore, the collection of program guides requires additional time and sometimes additional charges. In the program guide, complicated program information is often listed, and users need to spend a long time to search for the program they want, record the time, and watch or record with the recording device at the specified time.

Page 5 1227091 V. Description of the Invention (2) In order to improve the above problems, many conventional technologies have proposed improved methods for collecting program guides, using some devices or methods to collect the desired program request lists, so as to facilitate user selection. However, no matter the methods proposed by these conventional technologies are to serve the user actively or passively ask for it, the program itself may not be all played at the time shown in the program guide, it may be caused by temporary changes, interruptions, interruptions or other reasons. As a result, the user cannot know the program changes that occur after collecting the desired program guide, and even the program guide itself has not been modified in real time, often causing the user to miss the desired program or to no avail. In addition, if a user interrupts or records incompletely when recording a program, it is often discovered only after watching the program afterwards, and it takes time and effort to re-record at a specified time. Therefore, in order to allow users to watch the desired program more effectively without limiting the user's time, it is necessary to develop a new program pre-recording system, especially to automatically collect programs and automatically fill in incomplete records. Program pre-recording system for program segments. 3. [Inventive Content] One of the main objectives of the present invention is to provide a program 1 pre-recording system, which does not rely on the program guide. When the audio-visual content and program information are transmitted at the same time, the desired program can be selected to avoid the inconsistency between the program guide and the audio-visual content. The problem.

Page 61227091 V. Description of the invention (3) Another object of the present invention is to provide an automatic collection and recording system, which has both efficiency and correctness considerations, and collects the programs listed and not listed in the program guide for more watching at any time. And application. According to the above-mentioned purpose, the present invention provides a program pre-recording system, which mainly selects programs that meet the pre-stored selection conditions according to the program information contained in the program input signal, and records for future viewing; its characteristics are: The video content of the program is received together with the program information. The pre-recorded programs to be recorded are selected according to the program information. There is no need to rely on the program guide to pre-record the program. There will be no inconsistency between the video content and the program guide. Occurrence of incomplete or pre-recorded programs. 4. [Embodiments] Some embodiments of the present invention will be described in detail as follows. However, in addition to the detailed description, the present invention can be widely implemented in other embodiments, and the scope of the present invention is not limited, which is subject to the scope of subsequent patents. Furthermore, in order to provide a clearer description and easier understanding of the present invention, the parts in the diagram are not drawn according to their relative dimensions, and certain dimensions have been exaggerated compared to other related dimensions; irrelevant details have not been completely drawn. Out for simplicity of illustration. The inventor of the present invention first pointed out the many disadvantages of the conventional technology, mainly due to the following reasons:

Page 7 1227091 (4) In the past, if you want to use the festival, you need to have enough time to know the anti-program broadcasts before you can collect the festival ’s users ’festivals. V. Invention Description (1) Can be complicated by paper news Out of time, once the above is missed (2), users of the user's program guide have a hard time. (3) If you want to watch or play the program, the information is mostly concentrated in the program guide. The program guide can be transmitted through the broadcast, the Internet, or a specific program channel. Collecting or picking out the programs you want to watch will be time-consuming and labor-intensive. Many other users need to focus on listening or watching in real time, spend some time waiting for the next appearance, and users should think about which programs they want. The program-related information that may be changed after the user collects the program guide may be invalid, and it may also be updated or the user is not notified after the update, so that the information often cannot be viewed or pre-recorded. It is not possible to collect and pick out the program guide for a long time. In addition, you may not have time to watch the pre-recorded setting when the playback time is up. The inventor of the present invention then points out that the above common defects can be improved by the following methods: (1) The program content and program information are combined and transmitted at the same time to solve the lack of synchronization between the program content itself and the program guide and the difficulty of collecting the program guide. The reason is that the program information can be obtained in real time without relying on the program guide. Naturally, there are no temporary changes in the program, and the user cannot be notified. (2) Using a pre-recording device that can set personal preferences, when the above-mentioned programs are delivered, the program information can be obtained and the pre-recorded programs can be automatically determined and selected, so that the user does not need to spend too much time selecting programs and can watch them at any time.

Page 8 1227091 V. Description of the invention (5) Restrictions on time. According to the above discussion, as shown in the second figure, a preferred embodiment of the present invention is a program pre-recording system, which is mainly selected by the program selection device 14 according to the program information contained in the program input signal 12 Programs with pre-selected selection conditions are stored in the recording device 16 for future viewing; it is characterized by: The video and audio content of the program is received together with the program information, and the pre-recorded program to be recorded is selected according to the program information. In addition, the program guide is used to pre-record the program. There will be no inconsistency between the program audio and video content and the program guide, which will cause the program to be pre-recorded incompletely or to record unwanted programs. Here, the program input signal includes at least one of the following: program information, playing time, and audiovisual content. Among them, the program information is selected from the group selected by the program name, actors, directors, film location, series, individual programs, catalogs, categories, and film photography methods. In addition, the pre-stored selection conditions are selected from the group consisting of the play time, the duration of the project, the print time, the time interval, and related information to select and exclude associations and intersections. Furthermore, the recording and recording methods include recording and recording all relevant signals of the program, recording and recording only the audiovisual content, and audiovisual recording and recording. According to the composition and use examples of the embodiment described above, it can be known that this embodiment has the following advantages compared with the conventional technology: (1) This embodiment automatically detects whether the settings match the user's preset preferences. Program and save it for users to choose and watch in the future.

1227091 V. Description of the invention (6) It takes time to find the festival festival from the complicated program guide, and it is not limited by the broadcast time of the program, and can be viewed at any time after the program is broadcast. (2) In this embodiment, the audio-visual content and the program information are transmitted at the same time, and the program information is consistent with the audio-visual content, so as to screen the programs that are to be stored, so there will be no pre-recording of the program due to the inconsistency between the program guide and the audio-visual content. The situation occurs intact or recorded to unwanted programs. Obviously, although this embodiment is a program pre-recording system, it can be found from the discussion content that the focus of this embodiment is to combine the audio-visual content with its related information and spread it at the same time, and to integrate the content of the image, sound, etc. Whether it is a program or not is not necessarily related. For example, its audio and video content can be interrupted broadcasts, trailers, advertisements, and programs. In other words, the patent scope of the present invention is not limited to programs. Therefore, as shown in FIG. 3A, another preferred embodiment of the present invention is a program pre-recording method, which includes at least the following basic steps: first, receiving a program input signal as shown in step 31; and then as shown in step 32 , Analyze the received program input signal to separate the program information, playback time, playback time, video content, and other related information; then, as shown in step 33, compare the pre-stored selection conditions with the parsed program information, playback time, and playback Relevant information such as time, select the matching programs; further, as shown in step 34, save and select the selected programs; finally, as shown in step 35, check the integrity of the pre-stored programs of the stored programs to analyze the incomplete Save and record clips, add pre-stored selection criteria for re-recording the next time you receive the same clip.

Page 10 1227091 V. Description of the invention (7) At the same time, in step 35, any incompletely recorded segment can add the pre-stored program segment in the program from the relative start playback time to the relative end playback time as the time interval to add the In the pre-stored selection condition, the pre-stored program segment is re-recorded when the program is received in the time interval in the future. As shown in Figure 3B, first check out an incompletely recorded segment as shown in step 3 51; then, as shown in step 3 5 3, calculate the start and end time of the segment in the program; finally, as shown in step 3 5 As shown in FIG. 5, the obtained time interval is added to a pre-stored selection condition for re-recording when the same segment is received next. In addition, in step 34, when the program is stored, the program may be cut into a plurality of program segments according to a preset value, and the program segments are individually stored. As shown in the third C diagram, first, as shown in step 3 41, the program that meets the conditions is cut into a plurality of program segments according to a preset value, and then, as shown in step 3 42, the program segments are individually stored. Here, any incompletely recorded segment is added to the pre-stored selection condition using the relative program segment of the pre-stored program segment in the program as a time interval, so that the pre-stored program is re-recorded when the program is received later in the time interval Fragment. Referring to the 3D picture, as shown in step 3 52, first, if it is found that there is an incompletely recorded segment in a program segment, as shown in step 3 54, calculate the start and end time of the program segment in the program Then, as shown in step 3 5 6, add this program time interval to the preselection condition for re-recording the next time the same program segment is received. The advantage is that incompletely recorded videos are often concentrated in a certain period of time, which may be a continuous period of time, or it may be intermittently many times. The reason for this may be interrupted or external reasons.

Page 14 1227091 V. Description of the invention (8) Noise caused by the element, which may cause a large increase in pre-stored selection conditions and slow down the selection efficiency. When the program segment size is set appropriately, the selection efficiency can be improved. Here, the size of the program segment is not limited to be smaller than the size of the program itself, and may be the size of the entire program itself, or larger than the size of the program itself. For example, when the size of a program segment is equal to the size of the program itself, there is only one segment of the entire program. If there are any incompletely recorded segments, the next time the same program is received, they will all be re-recorded. In addition, because of the relationship between the storage media, the program segment may be larger than the program itself. For example, the storage medium is a disc. At least one storage unit for each program is a disc capacity. At this time, the program size may be smaller than the disc capacity. When checking the incompletely recorded segments, there are many ways to check whether the program information is intact, check whether a blank signal is stored, and check whether there are specific noises. As for one kind of check or all in parallel, this is not the implementation. Focus of the case. In addition, if a complete program contains program segments that are not related to the program, and the program information of the program segments is only related to the program segments, such as advertisements, previews and inserts, etc., it is considered the program itself Other programs. In other words, it can be seen that multiple programs are broadcast at a time. The processing methods of these program segments other than the programs themselves can be excluded by pre-selection of selection conditions, stored separately from the program itself during recording, and completely extracted from the program itself, or treated as part of the program.

Page 121227091 V. Description of the invention (9) Furthermore, in addition to the pre-recording selection conditions, which can be used to select the programs listed in the program guide, it can also be used to collect advertisements, previews and interruptions, which are not listed in the program guide. , Such as collecting instant news feeds of the day, collecting new ads within a week to know which new products are available or collecting upcoming new movie trailers, and so on. Obviously, the present embodiment uses various methods to process the program recording process, so as to correctly and completely record the desired program and use the program other than the program itself. In addition, the various methods used are not limited to which software or hardware must be executed, but are limited by the functions that must be achieved. In other words, this embodiment does not limit the corresponding system details. Therefore, as shown in the fourth figure, another preferred embodiment of the present invention is a program pre-recording system, which includes at least the following basic units: a receiving device 41, a program database 4, a program selection device 4, a video recording device 4, Audiovisual database 45 and program content inspection device. The receiving device 41 is used to receive a program input signal 12 which includes at least the video content of the program, the playback time and the program information. The above-mentioned program database 42 is used to store pre-recording selection conditions.
