Description of drawings
Describe the preferred embodiments of the present invention in detail by the reference accompanying drawing, it is clearer that above-mentioned purpose of the present invention and advantage will become, in the accompanying drawing:
Fig. 1 illustrates according to the record of key frame and/or the functional block diagram of reproducer of utilizing of the present invention;
Fig. 2 illustrates the operating process of utilizing the moving image recording method of key frame according to of the present invention; Know
Fig. 3 illustrates the operating process of utilizing the moving image reproducting method of key frame according to of the present invention.
Embodiment
Describe the present invention below with reference to accompanying drawings in detail.
With reference to Fig. 1, comprise according to moving image record of the present invention and/or reproducer: key frame detects and indexing unit 10, recording processor 12, recording medium 14, key frame position search unit 16 and reproduction processes device 18.Key frame detection and indexing unit 10 and recording processor 12 are corresponding to the moving image tape deck.Key frame position search unit 16 and reproduction processes device 18 are corresponding to the moving image transcriber.
Key frame detect and indexing unit 10 when the input coding moving picture data flow, detect according to the coding standard of input moving picture data flow and not have the scene variation, and if have the scene variation then detect key frame corresponding to representative picture.Then, key frame detects and the position of the key frame that indexing unit 10 marks are detected.Encoded moving picture data stream be receive from the scheduled broadcast channel or provide from external system.
For example, be based under the situation that the mpeg encoded standard is encoded in the input moving picture data flow, when the periodic mode of the frame interior (intra-frame) of input moving picture data flow was not normal frame interior periodic mode with the mpeg encoded operating such, key frame detected and indexing unit 10 determines to exist the scene variation.After it determined to exist the scene variation, the frame interior of Fa Shenging was detected as the key frame corresponding to representative picture first.In addition, the frame interior that detects in order to indicate is a key frame, marks the position of the frame interior that is detected.
The moving image transcriber comprises key frame position search unit 16 and reproduction processes device 18, the position data of the representative picture of this device searching record on recording medium 14, and only reproduce representative picture.In other words, the position data of the key frame that is recorded at the isolated area of recording medium 14 or with moving picture data stream of key frame position search unit 16 searching record.
Be under the situation of the trickplay modes (or fast forword play mode) that is used to appreciate whole plots in current reproduction mode, according to the key frame position data that is found by key frame position search unit 16, reproduction processes device 18 only reads the moving picture data stream corresponding to key frame, skip the reproduction position of recording medium 14 simultaneously, and be uncoded raw frames data with the data stream recovery that reads, it is presented on the screen.
Therefore, in according to moving image record of the present invention and/or reproducer, the user can find out the whole plots with the moving image content of high-speed retrieval easily, and can be the normal reproduction pattern with the high-speed retrieval mode switch when the scene that the user wants occurring.Therefore, owing to can enjoy the detailed moving image of the scene of wanting, the user can improve the satisfaction of reproduction mode.
Fig. 2 is an operating process of utilizing the moving image recording method of key frame according to of the present invention.
If the moving picture data stream of coding is provided as shown in Figure 1, then in step 21, detect whether there is the scene variation.In step 22, the position probing of the frame interior that will take place first after detecting the scene variation is the position corresponding to the key frame of representative picture.In step 23, the key frame position that mark detected is to indicate that it is the position of representative picture.In step 24, will have the moving picture data stream that is marked at wherein and be recorded in the recording medium 14 corresponding to the key frame position of representative picture.
Fig. 3 is an operating process of utilizing the moving image reproducting method of key frame according to of the present invention.
If be provided with the trickplay modes of the whole plots that are used to appreciate the moving image content, then in step 31, from recording medium 14 corresponding to the key frame position of representative picture.In step 32, skipping between the key frame in all unlabelled frames the moving picture data of playback record stream according to the key frame position data that in step 31, finds.In step 33, the moving picture data stream of reading is reverted to uncoded raw frames data.
As mentioned above, according to the present invention, when the record coding moving picture data flows, detect the key frame of representing the scene variation automatically and write down its position.During trickplay modes, the key frame position of searching record and only with high-speed retrieval corresponding to the moving picture data of key frame stream, thereby do not need user's operation can easily find out whole plots of moving image content.
In addition, owing to allow to appreciate whole plots, thereby when occurring the scene that the user wants in the process of watching whole plots, the user can switch to reproduction mode the normal reproduction pattern, thus the content that calling party is wanted in moving picture data flows easily.
From top description,, can make various modifications and not break away from aim of the present invention and scope it although it will be apparent to those skilled in the art that and illustrate and described particular form of the present invention.Therefore, the present invention is unrestricted except that appending claims.
