Method and apparatus for capturing consecutive frames in digital video
A method and an apparatus for capturing consecutive frames in digital video are disclosed. Through adding a function of capturing consecutive frames in digital video to digital televisions or digital recording equipments, the continuous fantastic frames in digital video can be displayed on the screen for users to watch and choose. Besides, with a recording function, those fabulous frames can also be preserved for the use of the follow-up view and demonstration. Finally, the purpose of capturing and storing best frames is achieved.
1. A method for capturing consecutive frames in digital video, comprising:
continuously receiving a digital video data, wherein the digital video data comprises a plurality of video frames;
decoding the video frames and storing a parameter of the digital video data;
playing the decoded video frames;
capturing a plurality of captured frames from the digital video data according to the parameter of the digital video data once receiving a capture instruction;
decoding the captured frames and storing the decoded captured frames; and
displaying the captured frames that had been decoded.
2. The method for capturing consecutive frames in digital video of claim 1 , further comprising:
selecting one of the captured frames as a chosen frame; and
performing an edit function on the chosen frame.
3. The method for capturing consecutive frames in digital video of claim 2 , wherein the edit function comprises storing the chosen frame.
4. The method for capturing consecutive frames in digital video of claim 2 , wherein the edit function comprises setting the chosen frame as one of a power-on frame, a stand-by frame, and a menu background frame.
5. The method for capturing consecutive frames in digital video of claim 1 , wherein the parameter comprises one of a frame rate, a movie format, and an encoding method of the video frames in the digital video data.
6. The method for capturing consecutive frames in digital video of claim 1 , wherein a predetermined time interval is configured between the captured frames.
7. The method for capturing consecutive frames in digital video of claim 1 , wherein the step of displaying the captured frames that had been decoded comprises displaying the captured frames by means of multi-window or single-window.
8. The method for capturing consecutive frames in digital video of claim 1 , wherein the digital video data comprises one of a digital broadcast program data and a data stored in an optical disk.
9. An apparatus for capturing consecutive frames in digital video, comprising:
a receiver for continuously receiving a digital video data, wherein the digital video data comprises a plurality of video frames;
a decoder for decoding the video frames and obtaining a parameter of the digital video data;
a player coupled to the decoder for displaying the decoded video frames;
a capture unit coupled to the receiver, the decoder, and the player for capturing a plurality of captured frames from the digital video data according to the parameter of the digital video data after receiving a capture instruction, and transmitting the captured frames to the decoder for decoding, wherein the decoded captured frames are then transmitted to the player for displaying; and
a storage unit coupled to the capture unit for storing the captured frames captured by the capture unit.
10. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein the receiver comprises:
a demodulator for demodulating the received digital video data into a transport stream (TS) format;
a demultiplexer coupled to the demodulator for recovering the digital video data with the TS format into a video raw data; and
a bit stream buffer coupled to the demultiplexer for temporarily storing the video raw data that will be subsequently decoded by the decoder.
11. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein the receiver further comprises:
a tuner for receiving a digital broadcast data by tuning a frequency and transmitting the received digital broadcast data to the demodulator.
12. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein the player comprises:
a frame buffer for temporarily storing the video frames; and
a display screen for displaying the video frames stored in the frame buffer.
13. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein the capture unit further comprises following functions:
selecting one of the captured frames as a chosen frame; and
performing an edit function on the chosen frame.
14. The apparatus for capturing consecutive frames in digital video of claim 13 , wherein the edit function comprises storing the chosen frame in the storage unit.
15. The apparatus for capturing consecutive frames in digital video of claim 13 , wherein the edit function comprises setting the chosen frame as one of a power-on frame, a stand-by frame, and a menu background frame.
16. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein the parameter comprises one of a frame rate, a movie format, and an encoding method of the video frames in the digital video data.
17. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein a predetermined time interval is configured between the captured frames.
18. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein the method of displaying the captured frames that had been decoded comprises displaying the captured frames by means of multi-window or single-window.
19. The apparatus for capturing consecutive frames in digital video of claim 9 , wherein the digital video data comprises one of a digital broadcast program data and a data stored in an optical disk.
