Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the flow chart according to the television picture capturing method of a preferred embodiment of the present invention;
Fig. 2 is the structural representation according to the set-top box of the intercepted television image of a preferred embodiment of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The invention provides a kind of television picture capturing method and set-top box, just can intercept whenever and wherever possible, and the picture data of intercepting can be stored in the nonvolatile memory, appreciate in the future for the user in picture displayed.Simultaneously, stored picture data also can be exported by USB interface, makes things convenient for user's unloading.Wherein, television picture capturing method comprises reception screenshotss index signal, stops the program stream of decoding; Read preceding decoding that stop to decode and obtain the picture data of last frame picture; Preserve described picture data.Wherein the screenshotss index signal is sent when the screenshotss button is pressed.Wherein the process of stored picture further comprises described picture data is converted to jpeg format; The picture data that is converted to jpeg format is kept in the nonvolatile memory; When preserving failure, send and preserve the failure prompting.And can be by the picture data of USB interface output preservation.Below just with specific embodiment technical scheme of the present invention is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the flow chart according to the television picture capturing method 100 of a preferred embodiment of the present invention.As shown in Figure 1, method 100 starts from step 102.
Subsequently, at next step 104, receive the screenshotss index signal.In the specific implementation process, this screenshotss index signal can be to send when the user presses screenshotss button on remote controller or the set-top box control panel.
Subsequently, at next step 106, stop the program stream of decoding.
Subsequently, at next step 108, read the picture data of the last frame picture that decoding obtains before the program stream that stops to decode.
Subsequently, at next step 110, preserve the picture data that reads in the step 108.Optionally, before preserving picture data, can carry out format conversion to picture data.Usually, the picture data that obtains of decoding is a bitmap format.Therefore, the picture data of bitmap format can be converted to such as but not limited to jpeg format, then the picture data after the storage format conversion.Picture data is converted to the jpeg format shared memory space of picture data greatly, thus once coming to store more picture data.In addition, in the specific implementation process, picture data can be kept at nonvolatile memory for example among the FLASH, so that can long preservation, and for read in the future.
When not had free space, will cause preserving failure such as but not limited to the nonvolatile memory that is used for the stored picture data.In this case, will send the preservation failure notification.
In addition, after the preservation of finishing picture data, also can carry out various file operations, such as but not limited to reading, delete, move etc. to the picture data of preserving.When carrying out picture data unloading or move operation, can export this picture data by USB interface.
In the specific implementation process, after the storage of finishing capturing picture,, then continue the decoding program stream if receive play instruction, recover the playing process of program.
Except television picture capturing method mentioned above, the present invention also provides a kind of set-top box of using this television picture capturing method intercepting television image, below just the structure of this set-top box is described in conjunction with Fig. 2.
Fig. 2 is the structural representation according to the set-top box 200 of the intercepted television image of a preferred embodiment of the present invention.As shown in Figure 2, set-top box 200 comprises decoder 202 and picture capturing module 204.
Decoder 202 is used for program stream 206 is decoded.
Read module 2042 is used to receive screenshotss index signal 208, and notice decoder 202 program stream 206 that stops to decode reads the picture data that decoding before stopping to decode obtains the last frame picture, and this picture data is mail to format converting module 2044.
Before picture data being stored in the memory module 2046, can carry out format conversion to picture data.Usually, the picture data that obtains of decoding is a bitmap format.Therefore, the picture data of bitmap format can be converted to such as but not limited to jpeg format, then the picture data after the format conversion be stored in the memory module 2046.Picture data is converted to the jpeg format shared memory space of picture data greatly, thus once coming to store more picture data.
Memory module 2046 is used for picture data (can be the picture data after the format conversion, also can be without the picture data after the format conversion).In the specific implementation process, memory module 2046 can be a nonvolatile memory, such as but not limited to FLASH, so that can the long preservation picture data, and for read in the future.When not had free space, will cause preserving failure such as but not limited to the nonvolatile memory that is used for the stored picture data.In this case, will send the preservation failure notification by read module 2042 (picture data need not to carry out format conversion) or format converting module 2044 (picture data need carry out format conversion).
Optionally, set-top box 200 also can comprise USB interface 210.After the preservation of finishing picture data, also can carry out various file operations, such as but not limited to reading, delete, move etc. to the picture data of preserving.Carrying out that picture data reads or during move operation, this picture data will for example be exported picture data 212 by USB interface 210 outputs.
In the specific implementation process, after the storage of finishing capturing picture, if receive play instruction, then picture capturing module 204 can notify decoder 202 to continue the decoding program stream, recovers the playing process of program.
By adding relevant screenshotss functional module, make set-top box provided by the invention just can intercept whenever and wherever possible, and the picture data of intercepting can be stored in the nonvolatile memory in picture displayed, appreciate for the user in the future.Simultaneously, stored picture data also can be exported by USB interface, makes things convenient for user's unloading.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
