Apparatus, systems and methods for user controlled synchronization of presented video and audio streams

1. A method comprising:

storing synchronization correction information in a memory of a media device, wherein the synchronization correction information specifies a predefined duration;

receiving a media content stream at the media device, the media content stream comprising a video stream and an audio stream;

communicating the video stream to a display for presentation to a user of the media device;

communicating the audio stream to one or more speakers for presentation to the user of the media device;

receiving a user initiated synchronization correction instruction;

retrieving the synchronization correction information from the memory of the media device in response to receiving the user initiated synchronization correction instruction; and

incrementally adjusting one of the video stream and the audio stream by a synchronization correction, wherein the synchronization correction adjusts presentation of the video stream with respect to the audio stream by the predefined duration that is retrieved in response to receiving the synchronization correction instruction.

2. The method of claim 1 , wherein incrementally adjusting one of the video stream and the audio stream by the synchronization correction comprises:

retarding presentation of the video stream by the predefined duration.

3. The method of claim 2 , wherein retarding presentation of the video stream by the predefined duration comprises:

selecting at least one image frame from a plurality of image frames of the video stream;

duplicating the selected image frame into a plurality of duplicated image frames, wherein a sum of presentation times of the selected plurality of duplicated image frames corresponds to the predefined duration of the synchronization correction;

inserting the plurality of duplicated image frames into the video stream; and

communicating subsequent image frames of the video stream to the display.

4. The method of claim 2 , wherein retarding presentation of the video stream by the predefined duration comprises:

selecting a plurality of non-adjacent image frames from a plurality of image frames of the video stream;

duplicating the selected plurality of non-adjacent image frames, wherein a sum of presentation times of the duplicated non-adjacent image frames corresponds to the predefined duration of the synchronization correction;

inserting the plurality of duplicated non-adjacent image frames into the video stream, wherein each non-adjacent duplicated image frame is inserted adjacent to its respective image frame; and

communicating subsequent image frames of the video stream to the display.

5. The method of claim 4 , wherein duplicating the selected plurality of non-adjacent image frames comprises:

duplicating each of the selected plurality of non-adjacent image frames two times; and

inserting the two duplicated non-adjacent image frames adjacent to their respective image frame.

6. A method comprising:

receiving a media content stream at a media device, the media content stream comprising a video stream and an audio stream;

communicating the video stream to a display for presentation to a user of the media device;

communicating the audio stream to one or more speakers for presentation to the user of the media device;

receiving a user initiated synchronization correction instruction; and

incrementally adjusting one of the video stream and the audio stream by a synchronization correction, wherein the synchronization correction adjusts presentation of the video stream with respect to the audio stream by retarding presentation of the video stream by a predefined duration associated with the synchronization correction instruction,

wherein incrementally adjusting one of the video stream and the audio stream by the synchronization correction comprises:

adding a predefined time delay between communication of each one of a plurality of image frames, wherein a sum of the time delays corresponds to the predefined duration of the synchronization correction; and

communicating subsequent image frames of the video stream to the display.

7. The method of claim 6 , wherein adding the predefined time delay between the communication of the plurality of image frames comprises:

adding the predefined time delay between adjacent ones of the plurality of image frames.

8. The method of claim 2 , wherein retarding presentation of the video stream by the predefined duration comprises:

generating a plurality of image frames, wherein a sum of presentation times of the generated image frames corresponds to the predefined duration of the synchronization correction;

inserting the plurality of generated image frames into the video stream; and

communicating subsequent image frames of the video stream to the display.

9. The method of claim 8 , wherein the generated image frame is defined by a color.

10. The method of claim 1 , further comprising:

receiving a user input that includes a duration that is associated with the synchronization correction;

generating the synchronization correction information in response to receiving the user input, wherein the synchronization correction information is based on the duration of the received user input; and

storing the generated synchronization correction information in the memory of the media device.

11. The method of claim 1 , further comprising:

receiving an input that includes a duration that is associated with the synchronization correction;

generating the synchronization correction information in response to receiving the input, wherein the synchronization correction information is based on the duration of the received input; and

storing the synchronization correction information in the memory of the media device, wherein the stored synchronization correction information specifies the predefined duration of the synchronization correction.
