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 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 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.

摘要： The invention provides systems and methods for providing compressed video data from multiple bit streams. The systems and methods apply a two-stage strategy. In the first stage, a conditioning step is performed on a bit stream comprising compressed video data which outputs a conditioned bit stream that is able to receive digital insertions without subsequent decompression of the compressed video data or removal from network packets. The conditioning includes recoding an incoming bit stream such that compressed video data in the bit stream immediately before and after a splice point does not have temporal reliance across the splice point. In the second stage, e.g., at a downstream network device, splicing of compressed video data from a second bit stream into the conditioned bit stream is performed. The splicing takes advantage of the changes made to the conditioned bit stream and may occur at the network packet level.

摘要： The present invention relates to systems and methods for efficient bit rate alteration of a bitstream to match an available channel capacity. The efficient bit rate alteration includes selective re-quantization of the compressed bitstream. Selective re-quantization according to the present invention applies multiple re-quantization schemes to different portions of a bitstream. In one embodiment, the multiple re-quantization schemes each have a different computational load. By selectively choosing which type of re-quantization is performed on each portion, efficient bandwidth scaling and data transmission may be achieved both when computational capacity is limited and when video data integrity is important.
