摘要:
Simple, computational efficient, and robust audio features are applied in a uniform program indexing method for picking up video segments relating to highlight plays in a recorded program worthy of being reviewed. By focusing on certain frequencies in an audio sequence of the program, a computational complexity of the uniform program indexing method is significantly decreased. With the aid of MFCC coefficients and a DFBE coefficient generated from the MFCC coefficients, audio patterns may be utilized for differentiating exciting events in the program from other unnecessary information. Scores corresponding to various audio segments are regarded as standards for picking up video segments in the program worthy of being chosen in a recorded highlight collection. Some low-level-feature parameters, some video segments having highlight-related visual characteristics, and a re-ranking procedure are utilized for enhancing precision of the scores for providing video segments worthy of being reviewed.

Methods and apparatus for setting channel contents are provided. A method includes: associating a specific channel with a specific program category; assigning a program to the selected specific channel when the specific channel is selected and the program corresponding to the specific program category is available from a live multimedia stream source; and assigning at least a pre-stored program corresponding to the specific program category from a storage device to the selected specific channel when the specific channel is selected and the program corresponding to the specific program category is unavailable from the live multimedia stream source. Therefore, a user can easily and conveniently watch programs corresponding to a favorite program category on the selected specific channel.

A method for indexing a sports video program carried by a video stream is disclosed. The method includes temporarily indexing a plurality of shots of the video stream by performing shot detection. In addition, the method further includes extracting a plurality of shots of the sports video program from at least one portion of the shots indexed during the shot detection at least according to low level visual features of the at least one portion, whereby the extracted shots are temporarily kept indexed. Additionally, the method further includes validating a plurality of shots by comparing one of the extracted shots with at least the others of the extracted shots, whereby the validated shots are kept indexed for use of playback of at least one portion of the sports video program.

A method of generating pixel data of a missing block in an image frame is disclosed. Edge points are detected from neighboring image side adjacent to the missing block. A direction is calculated for each edge point. Edge lines are formed from edge points based on the direction thereof to partition the missing block into a plurality of missing regions. Data for missing pixels in each missing region are then calculated using reference pixels from neighboring image sides adjacent to the missing region.

摘要:
A method for adaptively estimating a remaining video length in real time for a user's convenience while viewing at least one program, includes calculating an average value of the viewed length of each viewed segment of the at least one program, and calculating the number of index points corresponding to remaining segments to derive a remaining number of index points. The method further includes multiplying the average value by the remaining number to estimate the remaining video length.
