摘要： According to the present invention, methods and apparatus for performing efficient inverse transform operations are provided. Zero patterns are identified in a block of transform coefficients to derive zero pattern information. Using the zero pattern information, inverse transform operations are performed on a subset of the columns of the block of transform coefficients. Zero patterns can optionally be identified in the resulting block. One-dimensional inverse transform operations are then performed on the rows of the resulting block to complete the inverse transform. In another example, one-dimensional inverse transform operations can be performed first on the rows and then on the columns.

摘要： A method for extracting a fingerprint data from video/audio signals, comprising the steps of sending a series of video frame images into a fingerprint extractor; extracting a fingerprint data through the fingerprint extractor; and storing the fingerprint data into a fingerprint database, characterized in that, in the fingerprint extractor, said method further comprises the sub-steps of storing the video frame images in a frame buffer which accepts a new video frame image and discards the oldest video frame image in a first in first out (FIFO) fashion; sampling the video images by a sub-sampler which operates on one video frame image at a time, so that the output of the sub-sampler contains data samples obtained from multiple video frame images while the video image content itself is discarded, and after each video frame image is sampled at the head of the frame buffer, it is discarded after the sampling; making the data samples to go through a divider which divides the data samples into groups of video frames so as to be organized as one fingerprint segment after another one; incorporating optional information by a formatter to the fingerprint segment so as to form the fingerprint data, at the output of the formatter, the video image content is discarded, only the fingerprint data and the associated optional information remain; and transferring the fingerprint data and the associated optional information by a transfer buffer to the fingerprint database. According to the present invention, the method for extracting a fingerprint data from video/audio signals facilitates the automatic identification, archiving and search of video content without the need for human visual inspections.

摘要： A method for facilitating the search of video content by matching fingerprint data extracted from a given video content with existing video fingerprint data already stored in the database. The system consists of systems for extracting fingerprint from the video content, the database for storing plurality of fingerprint data entries from known video content segments and systems for comparing between the fingerprint data obtained from the video content with the fingerprint data entries obtained from the fingerprint database. Once a match is identified, the video content associated with the matched fingerprint in the database is said to be identified by the information in the database associated with the match. The information referenced from the database includes archived video information.

摘要： A merchant initiates a payment process by sending transaction details, merchant information, and a user or customer phone number to a payment service provider. The payment service provider sends a message to the user device, either asking the user to confirm the payment or communicating an authorization code. In the former, the user may be asked to simply confirm or communicate a user code. In the latter, the user communicates the authorization code to the merchant, who then communicates it to the payment servicer provider. In either case, once received and approved, the payment service provider sends a confirmation message to the merchant and the user that the payment has been approved and processed. Communication can be by text or verbal.

摘要： A packet schedule timestamp is provided. A schedule information packet includes a packet schedule timestamp that represents the relative timing of data packets in a particular bitstream of a multiplexed transport stream. The schedule information packet further provides information about the timing of packets within a bitstream or multiple bitstreams before actual packet arrivals. Look-ahead processing techniques are provided to improve the efficiency of compressed bitstream storage and delivery, such as program stream to transport stream conversion and statistical multiplexing. The packet schedule information can be inserted into the bitstream it describes for transmission or storage with it. Other features, such as timing reconstruction, are also provided. The packet schedule information can be used to reconstruct the timing of the transport packets to their original state.
