Content serialization by varying content properties, including varying master copy watermark properties
This disclosure describes novel methods for generating unique copies of content. One method combines the functions of the master copy and unique copy watermarks. In particular, the method generates a unique copy by varying the manner in which the master copy watermark is embedded in unique copies of a content item. In one embodiment, the master copy watermark is repeated within the content item and its location is varied in a unique pattern that comprises the unique copy watermark. The unique copy is generated by producing a copy in which master copy watermarks are embedded in a unique pattern. For instance in one embodiment, the locations of the master copy watermarks in the content item are represented as a vector of delta values in which each delta value corresponds to the distance between a corresponding instance of the master copy watermark, and a neighboring instance of the master copy watermark. This vector is stored in a transaction record in association with transaction information, such as information identifying the master copy and information associated with the unique copy. Other ways of representing the unique pattern of attributes of the master copy watermark are also possible. In other embodiments, properties of the master copy watermark other than its location are varied through the content. The unique copy watermark is conveyed in the vector of deltas in these properties of the master copy watermark. Some examples of these properties of the master copy watermark signal include phase characteristics (e.g., the phase shift of a watermark carrier signal), frequency magnitude characteristics, etc. These properties are varied in a manner that does not alter the information carried in the master copy watermark. However, it does provide a variation that creates a unique copy, and the unique copy watermark is conveyed in this variation. The variation in location of the instances of the master copy watermark can be in different domains, such as a spatial domain, a time domain, a time-space domain, a transform domain (including frequency transform domains), a compressed domain, etc. |

Residual echo detection based on non-causality
Methods and systems detect residual echo in an audio signal in a non-causal manner. A non-causal residual echo detector allows accurate detection of any residual echo from an AEC (acoustic echo canceller). The non-causally detected residual echo may be utilized to perform various actions such as selecting between different causal AECs, tuning a causal AEC, and/or characterizing the performance of the causal AEC. Aspects leverage an understanding that the information about residual echo being present in a signal does not have to be causal in the sense that it is acceptable and even advantageous to know some time afterwards (e.g., after a signal has undergone acoustic echo cancellation and is output for further processing or transmission) that a residual echo was present in the signal. Such an approach is different from the case of an AEC, which needs to know right away, with a fairly low signal delay involved, whether residual echo is present. |

Method to schedule multiple traffic flows through packet-switched routers with near-minimal queue sizes
A method to schedule multiple traffic flows through a multiplexer server to provide fairness while minimizing the sizes of the associated queues, is proposed. The multiplexer server minimizes a quantity called the maximum Normalized Service Lag for each traffic flow. In each time-slot, the normalized service lag of every traffic flow may be updated by adding the normalized lag increment value, whether or not there is a packet in the queue associated with the flow. In each time-slot, a multiplexer server selects a traffic flow to service with an available packet and with the maximum normalized service lag. When the traffic rate requested by each traffic flow is stable, the multiplexer server schedule may repeat periodically. Efficient methods to compute periodic schedules are proposed.

Methods and apparatus for preventing head of line blocking for RTP over TCP
Methods and apparatus for processing and using TCP packets to communicate RTP packets are described.

Closed enclosure with probe for identifying contents of enclosure
An automatic data collection system tracks articles by providing a robust electromagnetic (EM) field within an enclosure in which the articles are stored. Respective data carriers, such as RFID tags, attached to each article respond to the electromagnetic field by transmitting data identified with each article. An RFID scanner receives the transmitted RFID tag identification data and a processor compares the received identification data to a data base. The data base associates the identification data with data concerning the medical article to which the RFID tag is affixed, such as the name of the medicine, the size of the dose, and the expiration date. The processor is also programmed to keep track of the number of articles of a particular type remaining in the enclosure, to note receipt of an article in the enclosure, and to note removal of the article. |
