Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below will the present invention be described in further detail by specific embodiment and relevant drawings.
Please refer to Fig. 1, for the present invention for realizing system block diagram of the present invention, comprise a signal source, have the processor of PVR function such as television equipment or TV set-top box, display unit, input equipment and External memory equipment.
Please refer to Fig. 2, be labeling method flow chart of the present invention.At two options of UI layout setting: one is " mark ", if the user need close certain section TV programme of not finishing watching when wishing that again continue to watch next time, can click this tag entry, then system can write down information such as current play position, programm name, picture sectional drawing, is made into label file and is stored in the middle of the external memory storage.Another is " bookmark " item, and " mark " information that function write down will show in this interface, for user search, use.
PVR is called for short TS by recording Transport Stream() finish recording of video.When the user when watching one section PVR video, if use " mark " item, then system is in recording TS stream, with current frame as a reference, retrieve key frame forward, when retrieving extremely nearest key frame, will intercept picture shown in the current key frame, and this key frame position and this programm name will be stored as label.
In order to allow the user experience the time schedule of the program of watching more intuitively, system can calculate this key frame simultaneously and record the side-play amount of the position, packet header of TS stream file with respect to this section, obtains temporal information.Computational process is as follows: at first obtain the number of frames between this key frame and the start frame; Obtain the speed of playing frame number then; Divided by the frame playback rate, obtain a time value with number of frames, this time value can be shown in the middle of the user interface, this label for reference be in video playback which constantly.System also is written to number of frames in the index file, so that when reading bookmark next time, can carry out inverse operation according to this numerical value, obtains the position of the key frame that will locate.System can the intercepting key frame shown in time of obtaining of picture and computing, it is stored in the middle of the bookmark file.
In the middle of being stored in external memory storage from the resulting bookmark file of " mark " function.This file provides to a used key message of bookmark index.Simultaneously, the application program of bookmark item will be read in this document, and recorded information is resolved, and fill out on the interface to show on the corresponding position, select for the user.If no label file then when breathing out this label hurdle, ejects prompting " no label ".
