Embodiment
Below will be described in detail with reference to drawings and Examples to broadcast recording device and method.
Fig. 2 is in order to record the device of DMB (Digital Multimedia Broadcasting) broadcasting, and it comprises: the DMB Department of Communication Force 210 that carries out two-way communication with the DMB communication network; Set the configuration part 220 of the DMB broadcasting image quality that receives by above-mentioned DMB Department of Communication Force 210; Record the portion that records 230 of the DMB broadcasting of reception; The search part 240 of retrieval DMB broadcasting; To above-mentioned configuration part 220, record the control part 250 of portion 230, search part 240 and the control of DMB Department of Communication Force 210 executive systems and store the reservoir 260 of recording the DMB broadcast data.
Foregoing is in order to record the device that DMB broadcasting constitutes, to have omitted the description and the diagram of the funtion parts such as broadcast viewing that have nothing to do with main contents of the present invention.
DMB Department of Communication Force 210 is the communications components that can carry out two-way communication with the DMB broadcast system, watching of DMB broadcasting can be set or image quality when recording according to user's requirement in configuration part 220, record portion 230 and record user-selected broadcasting, and be stored in the middle of the reservoir 260.
The mode that above-mentioned configuration part 220 is selected to record image quality roughly is divided into two kinds, a kind of is that classification user according to program selects the own image quality of being wanted, another kind is to set image quality according to the subject matter of program, and whether the data space abundance of the above-mentioned reservoir 260 of foundation in addition, sets image quality.
For example, mode 1, the program code name that utilizes the user to want, or related-program can preserved program when playing, the image quality of recording this moment can be set at high, medium and low or recording audio etc. only.
Mode 2, the user does not directly select program, also has each subject matter of caricature etc. generally speaking according to film, advertisement, physical culture, can be set at corresponding image quality and stores.
Under each situation, utilize and set recorded program, or total reproduction time of the program of a certain subject matter that will record, when recording, can predict the size of this document according to the image quality of having set.Before recording beginning, confirm remaining data space,, can reduce image quality successively or according to the priority that the user sets, record according to the size of remaining space if work as remaining space as a child than the file that predicts.
For aforesaid way, be described in detail below.
The DMB broadcast recording device that comprises above-mentioned formation, the user sets the image quality that needs by configuration part 220, receives at the DMB Department of Communication Force in the middle of 210 the DMB broadcasting, set the channel that need record by search part 240 retrievals after, and indication is recorded.Next record portion 230 and will be stored in reservoir 260 to relevant broadcasting with the image quality of having set.
As mentioned above, control part 250 reduces image quality according to the control of reservoir 260 remaining spaces makes broadcast recording finish, and avoids because the situation of the Halfway Stopping taped broadcast that the deficiency of data space causes takes place.
Record for DMB, be described in detail below.
The user selects to set image quality (S301) according to the subject matter type of DMB broadcasting as shown in Figure 3.That is, the type of film, advertisement, physical culture etc. is set the image quality of recording in advance.
Then as Fig. 2, recorded image quality (S302) according to what the data space selection was suitable for.
Above-mentioned subject matter type of foundation and data space carry out after the image quality setting, the user selects channel (S303) in order to record DMB broadcasting, control part 250 is judged the subject matter type of the broadcasting that receives, and calculates after the data necessary space the existing remaining data space (S304) of retrieval.
Now above-mentioned steps (S304) is enumerated and had more style and describe.When the DMB broadcasting that need record was film, the control part 250 preferential image quality of selecting to meet film, when recording according to the image quality of setting, can roughly calculate required data space at total projection time of the relevant film of utilization.
Then control part 250 retrievals have remaining data space now.
According to above-mentioned result for retrieval, calculate remaining data space when sufficient, portion 230 is recorded in control part 250 controls, and related-program can be recorded according to the image quality that the subject matter type is set.
But in step (S305), if when remaining data space can not satisfy needed data space, the image quality that control part 250 is selected to set according to the setting data capacity in the steps (S302) is recorded (S306).
And if above-mentioned DMB broadcasting constantly changes the subject matter type, control part 250 continues the change image quality according to the subject matter type and the remaining data space of change, and control is recorded portion 230 and recorded.
As mentioned above, utilize the projection time information and the image quality of selected program, control part 250 calculates and stores required requisite space, judge whether reservoir 260 also leaves the amount of space that is calculated, if can be prompted to the user when space is not enough, or reduce image quality according to the order of user's automatic setting and make it possible to finish and record, prevent because the deficiency in space the phenomenon that causes recording process to interrupt.
Following embodiment according to subject matter type and data space setting image quality.
As shown in Figure 4, according to subject matter type separately, the order of image quality of when the data space abundance, setting and the change image quality of when data space is not enough, setting.
For example, when recording film,, records data space if being set at high image quality when sufficient; Also can be according to the remaining data space, by the order of change, successively be set in image quality or following (low) image quality.
DMB broadcasting is digital broadcasting, so broadcast program has separately been comprised the information of total projection time, on the DMB broadcast receiver, can discern the type and the projection time of broadcast program separately, utilize above-mentioned information, according to image quality, can calculate required data space, and record by this space.
Broadcast recording device and method according to the embodiment of the invention, be when bi-directional digital broadcasting is provided, the broadcast recording of liking is recorded for the own image quality that needs or according to the image quality of subject matter type setting, made users can access the broadcast data of the image quality of being wanted.According to these characteristics, so long as correct understanding the present invention, people with association area knowledge in thought range of the present invention, select by the choice of inscape, the embodiment that creates other is easy to do thing.
