Automatic playback overshoot control system and method

摘要

An automatic overshoot control system and method can enable a user to more easily terminate a trick mode (e.g., fast forward or rewind) at an intended point in program material. For example, after a trick mode, a user can initiate display of audio or video at a particular intended point in the program material while minimizing a need to manually adjust. The system determines an offset and tracks a preview position within the program material displayed as a trick mode preview incorporating the offset. The system also tracks an actual position within the program material based on the preview position and offset. The actual position corresponds to a predicted location that the user desires upon terminating the preview trick mode. When the preview trick mode is terminated, normal playback of the program material is resumed at the actual location corresponding to the user's intended location in the program material.

主权项

1. A method for controlling overshoot associated with a trick mode terminate command used for displaying program material, comprising:
receiving a trick mode command at an actual position of the program material; determining an offset based on user reaction time; displaying a trick mode preview of the program material starting at a preview point in the program material that is displaced from the actual position by the offset; updating the actual position based on elapsed time, wherein said actual position is displaced from the preview point by the offset; terminating the trick mode preview according to the trick mode terminate command; and displaying, according to the trick mode terminate command, the program material associated with the updated actual position to compensate for the overshoot associated with the trick mode terminate command.
