Embodiment
Below with reference to accompanying drawing, describe the specific embodiment of the present invention in detail.
Fig. 1 is the overview flow chart according to the caption presentation method of the embodiment of the invention.As shown in Figure 1, the method may further comprise the steps: S102, main control chip generates the caption content that will show, and be written to Digital Signal Processing (DSP) chip (namely by the caption content that the shared drive mode will show, media processing chip) correspondence memory zone is central (wherein, suppose that total N piece zone needs overlapping text, then at the internal memory of the suitable size of dsp chip one side application N piece, is used for depositing caption content); S104, main control chip issuing message are to dsp chip, and the order dsp chip reads corresponding internal memory; And S106, dsp chip shows subtitle superposition according to the coordinate position in the message to video image.
Wherein, when the main control chip issuing message to dsp chip, when order dsp chip cancellation showed corresponding caption content, dsp chip no longer read correspondence memory, thereby can wipe the caption information on the video image that already is added to.
The below further specifies the specific embodiment of the present invention as an example of 6834 main control chips, DM642 dsp chip example.
Fig. 2 opens up memory headroom for the schematic flow sheet of the process of depositing caption content according to the dsp chip of the embodiment of the invention.As shown in Figure 2, this process may further comprise the steps: S202, and in the internal memory of DM642 media processing chip, open up some block spaces and be used for depositing captions, suppose to have N place captions, then can apply for the memory headroom that the N piece is continuous; S204, the function that 6834 main control chips provide by driving get access to the first address ADDRESS1 of the mapping address of the captions shared drive that the DM642 media processing chip opens up.
Fig. 3 is according to the schematic flow sheet of the main control chip of embodiment of the invention control media processing chip with the process of subtitle superposition to the video image.As shown in Figure 3, this process may further comprise the steps: S302, and the captions that needs are shown convert dot matrix to; S304,6834 main control chips obtain the first address ADDRESS1 of the captions shared drive of DM642 media processing chip by driving, calculate again the side-play amount ADDRESS2 of captions stored memory address and first address according to the concrete regional location that will show, thereby the address that draws current captions storage is (ADDRESS1+ADDRESS2), the captions dot matrix that generates is write in the corresponding internal memory go; After S306, captions write successfully, issuing message notice DM642 media processing chip went to get the captions dot matrix in the corresponding internal memory; And S308, the DM642 media processing chip is added to the captions dot matrix on the video image, thereby the caption content that will show is presented on the corresponding position.
Fig. 4 is the schematic flow sheet according to the process of the main control chip control media processing chip deletion captions of the embodiment of the invention.As shown in Figure 4, this process may further comprise the steps: S402, and 6834 main control chip issuing messages notice DM642 media processing chip is wiped the captions of assigned address; S404, DM642 media processing chip no longer are added to the captions dot matrix of assigned address on the video image, thereby have realized wiping effect.
Fig. 5 is the logic diagram for the caption display system of realizing said process.As shown in Figure 5, this system comprises: captions generation unit 502 is used for generating the caption content that will show, and the caption content that will show is write in the correspondence memory zone of captions memory cell; Show indicating member 504, be used for to Subtitle Demonstration unit transmission content idsplay order; And Subtitle Demonstration unit 506, be used in response to the content idsplay order, from the correspondence memory zone of captions memory cell, extract the caption content that will show, and the caption content that will show is added to shows on the video image.
