Systems, methods, and apparatus for trick mode
Presented herein are system(s), method(s), and apparatus for a trick mode. In one embodiment, there is presented a system for displaying video data. The system comprises a buffer and a first circuit. The storage receives a normal video stream. The first circuit generates a trick mode stream from the normal video stream.
1 . A method for providing video data, said method comprising:
transmitting a normal video stream representing video content, wherein the normal video stream is for normal playback; and
transmitting a trick mode stream representing the video content, wherein the trick mode stream is for trick mode play.
2 . The method of claim 1 , wherein the trick mode stream comprises fewer pictures than the normal video stream.
3 . The method of claim 1 , wherein the trick mode stream comprises pictures with lower resolution than pictures from the normal video stream.
4 . The method of claim 1 , further comprising:
encrypting the normal video stream.
5 . The method of claim 1 , wherein the video content comprises a plurality of pictures, and wherein the method further comprises:
encoding a particular picture from the plurality of pictures to form a portion of the normal video stream;
encoding the particular picture from the plurality of pictures to form a portion of the trick mode stream; and
encoding another picture from the plurality of the pictures for the normal video stream after encoding the particular picture from the plurality of pictures to form portions of the normal video stream and the trick mode stream.
6 . The method of claim 5 , wherein encoding the particular picture from the plurality of pictures to form a portion of the trick mode stream further comprises:
encoding the particular picture with a lower resolution than the resolution for the normal video stream.
7 . A system for providing video data, said system comprising:
a transmitter for transmitting a normal video stream representing video content, wherein the normal video stream is for normal playback, and for transmitting a trick mode stream representing the video content, wherein the trick mode stream is for trick mode play.
8 . The system of claim 7 , wherein the trick mode stream comprises fewer pictures than the normal video stream.
9 . The system of claim 7 , wherein the trick mode stream has a lower resolution than the normal video stream.
10 . The system of claim 7 , wherein the video content comprises a plurality of pictures, and wherein the system further comprises:
an encoder for encoding a particular picture from the plurality of pictures for the normal video stream, encoding the particular picture from the plurality of pictures for the trick mode stream and encoding another picture from the plurality of the pictures for the normal video stream after encoding the particular picture from the plurality of pictures for the normal video stream and the trick mode stream.
11 . The system of claim 7 , wherein the video content comprises a plurality of pictures, and wherein the system further comprises:
a first encoder for encoding a particular picture from the plurality of pictures for the normal video stream; and
a second encoder for encoding the particular picture from the plurality of pictures for the trick mode stream.
12 . The system of claim 11 , wherein the second encoder encodes the particular picture with lower resolution than the first encoder.
13 . A system for processing video data, said system comprising:
storage for receiving a normal video stream; and
a first circuit for generating a trick mode stream from the normal video stream.
14 . The system of claim 13 , wherein the storage stores the trick mode stream.
15 . The system of claim 13 , further comprising:
a second circuit for decrypting the normal video stream, thereby resulting in a first decrypted normal video stream.
16 . The system of claim 15 , further comprising:
a third circuit for decoding the first decrypted normal video stream, thereby resulting in a first decoded decrypted normal video stream.
17 . The system of claim 15 , wherein the first normal video stream is discarded after generating the trick mode stream.
18 . The system of claim 15 , wherein the normal video stream is decrypted after receiving a decryption key, thereby resulting in a second decrypted normal video stream.
19 . The system of claim 18 , wherein the second decrypted normal video stream is provided for display.
20 . The system of claim 19 , wherein the trick mode stream is provided for display after receiving a request for a trick mode function.
