To describe the structure of video decoder according to another embodiment of the present invention below in detail.
Fig. 3 is the block diagram that illustrates the structure of video decoder according to another embodiment of the present invention.As shown in Figure 3, be according to the video decoder 200 ' of present embodiment and the difference between the decoder in the foregoing description 200: video decoder 200 ' also comprises control module 205, writes switch 206 and reads switch 207, and memory module 202 comprises two storage medium 202a and 202b.Because the corresponding component according to the video decoder 200 in the 26S Proteasome Structure and Function of other parts of the video decoder 200 ' of present embodiment and the foregoing description is identical, therefore in order to make specification simpler and clearer, utilize identical Reference numeral to represent these parts, and omitted being repeated in this description about these parts.
In video decoder 200 ' according to present embodiment, control module 205 control writes switch 206 and reads switch 207, makes the order that reads of the storage order that can control two storage medium 202a and 202b as required and storage medium 202a and 202b.
To in the decode procedure of video decoder 200 ', the storage order of control module two storage medium 202a of 205 controls and 202b and the flow process that reads order of this two 202a and 202b storage medium are elaborated below.Because the video such as the high definition film has a plurality of video files usually at present, therefore, suppose the situation that exists a plurality of video files to play here.
Beginning a plurality of video files when terminal equipment 100 copies to video decoder 200 ', control module 205 at first sends to control command and writes switch 206, thereby control writes switch 206 video file (as, video file 1) is copied to storage medium 202a.Therebetween, control module 205 is according to from the attribute information of the video file of terminal equipment 100 and the attribute information of storage medium 202a, but whether the relation between the memory space of the size of judging video file and storage medium 202a is write completely with definite storage medium 202a.
Do not write under the full situation at storage medium 202a, control module 205 by write switch 206 allow with the further part of video file (as, video file 2,3... etc.) be stored among the storage medium 202a to make full use of memory space.In this case, after if the duplicating of all video files finished, storage medium 202a is not write full yet, and then control module 205 instructions are read switch 207 selection storage medium 202a conducts and will be read the storage medium of video file to decode from it, and do not use storage medium 202b.
But the size at video file causes storage medium 202a to be write completely greater than the memory space of storage medium 202a; perhaps writing a plurality of video files at storage medium 202a causes storage medium 202a to be write under the full situation; control module 205 storage medium 202a are set to a read states; promptly; can not store new video file to storage medium 202a, thereby the video file that protection will be play is not covered by other data.
Then, control module 205 is to writing controller 206 transmitting control commands, to copy among the storage medium 202b by the further part of writing controller 206 with video file.
Therebetween, for example first video file (as, video file 1) is written among the storage medium 202a, or storage medium 202a is set to after the read states, control module 205 is to reading switch 207 transmitting control commands, thereby allows video decode module 203 to read the video file that will play to decode from storage medium 202a.
Then, also write when full at storage medium 202b, control module 205 detects the decoding work whether video decode modules 203 have been finished at the video file among the storage medium 202a.
If finished decoding work at the video file among the storage medium 202a, then control module can be set to a read states by storage medium 202b, storage medium 202a is set to the state of can writing simultaneously, thereby allows by writing switch 206 further part of video file to be written among the storage medium 202a.Meanwhile, control module 205 selects storage medium 202b as reading the storage medium of video file to decode from it to reading switch 207 transmission instructions, and video decode module 203 can continue to read video file from storage medium 202b by reading switch 207 thus.
If also do not finish the decoding work at the video file among the storage medium 202a, then control module 205 sends the transmission that order suspends video file to writing selector 206.Then, after finishing at the decoding work of the video file among the storage medium 202a, control module 205 storage medium 202a are set to the state of can writing, and instruction writes selector 206 further part of video file is copied among the storage medium 202a, works with duplicate (transmission) that recover video file.
When all video files that will play all decode finish after, control module 205 is removed the video file in all storage mediums (201a, 202a), and all storage mediums are set to the state of can writing.
Pass through aforesaid operations, control module 205 is according to the read/write state of storage medium (202a, 202b) and the decoding situation of video file, in storage medium 202a and storage medium 202b, switch, thereby can realize the consecutive access of file and broadcast continuously with finite storage space.For example, during the broadcast of the video file in storage medium 202a, the further part of store video files in storage medium 202b, and during the broadcast of the video file in storage medium 202b, the further part of store video files in storage medium 202a, thus the broadcast of video file can not interrupted.
In addition, it should be noted that, though described the storage order of control module 205 control store medium 202a and 202b and read flow process in proper order with said sequence, also can carry out the operation that be used for the storage order of control store medium 202a and 202b and read order not according to said sequence.For example, can begin with first video file (as, just begin the decoding work of this video file when video file 1) copying to storage medium 202a, and needn't wait until that this video file is written among the storage medium 202a, or storage medium 202a is set to the decoding work that a read states begins this video file afterwards again.
In addition, control module 205 need not to be write at storage medium 202b checks just whether the decoding work of storage medium 202a is finished when full, in case the decoding work of storage medium 202a is finished, control module 205 just immediately storage medium 202a be set to the state of can writing, thereby allow the writing of further part of video file.
With the above-mentioned video decoder 200 that comprises two storage mediums " access control procedure similar, control module 205 judges in the ablation process of video file whether current storage medium is write full.
Particularly, full if storage medium 202a is write, then control module 205 storage medium 202a are set to a read states, and by writing switch 206 further part of video file are written among the storage medium 202b.Then, full if storage medium 202b is also write, then control module 205 also is set to a read states with storage medium 202b, and by writing switch 206 further part of video file is written among the storage medium 202c.
Therebetween, reading in the process of video file, control module 205 is based on playing sequence, selects the storage medium that will be read by the video decode module by reading switch 207.
Particularly, for example, control module 205 selects storage medium 202a to be used as the reading object of video decode module 203 based on playing sequence by reading switch 207, and judge whether storage medium 202a is in a read states (that is, whether this storage medium 202a is write full).If this storage medium 202a is in a read states, then after the decoding of all video files of this storage medium 202a is finished, control module 205 this storage medium 202a are set to the state of can writing, and select storage medium 202b as reading object by reading switch 207.Similarly, control module 205 judges successively whether storage medium 202b and 203b are in a read states (that is, whether storage medium 202b and 203b are write full).Then, control module 205 is carried out with the processing of carrying out at storage medium 202a at storage medium 202b, 203b and is similarly handled.
In addition, if after storage medium 202c being write completely, also have the video file that needs broadcast, whether then whether the memory state of control module 203 detection of stored medium 202a is a read states, just finish at the decoding work of all video datas among the storage medium 202a.If storage medium 202a is for can write state, then the decoding work of all video datas among the storage medium 202a has been finished in expression.Therefore, control module 203 can continue to copy among the storage medium 202a by the further part of writing controller 206 with video file.In addition, if storage medium 202a is a read states, then control module 203 instruction writing controllers 206 suspend duplicating of video file, till the decoding work of all video datas in having finished storage medium 202a.In addition, similarly, if storage medium 202b and 202c also are in a read states, then control module 205 can also be carried out identical processing to storage medium 202b and 202c and allow to continue to write video data.
In the present embodiment, read storage and the decoding work that mode is carried out video file with sequential storage and order, yet, alternatively, as long as control module 205 can obtain the corresponding relation of video file and memory location (which storage medium), just can video file be stored in the storage medium that can write arbitrarily, and it is set to a read states after this storage medium is write completely by writing switch 206.In addition, in reading process, according to the corresponding relation between playing sequence and video file and the storage medium, control module 205 can by read switch 207 select the storage medium corresponding with wanting decoded video files as reading object carrying out the decoding of video file, and this storage medium is set to the state of can writing to allow the further part of further store video files after the decoding of video file is finished.
In addition, in the above-described embodiments, writing storage medium forbidden/allowed to control module 205 by the read-only/state of can writing that storage medium is set.Alternatively, control module 205 can be relevant with each storage medium by setting up, represent that the information whether this storage medium can be write to control writing each storage medium by writing switch 206.For example, if this information is " 1 ", then the expression storage medium corresponding with this information do not write and expired, and, can write video file to this storage medium that is.On the contrary, this information is " 0 ", and then the expression storage medium corresponding with this information write and expired, and, cannot continue to write video file to this storage medium that is.Similarly, control module 205 can also be according to this information by reading the read operation of switch 207 controls to each storage medium.For example, finish at after the reading of particular memory medium, control module 205 can with corresponding to the information setting of this storage medium for " 1 " to allow writing data to this storage medium.In addition, the information that whether can write about each storage medium of the format management that can also tabulate of control module 205.
In the above-described embodiments, described memory module 202 and had the example of two storage mediums and three storage mediums, alternatively, can also comprise more storage medium so that bigger memory capacity to be provided according to the video decoder of the embodiment of the invention.
