Methods and apparatus related to content sharing between devices

A method, comprising:

• receiving a first portion of a signal from a communication device via a communication channel;
• determining, based on the first portion of the signal, a parameter value used for identification of a product of interest;
• calculating a probability value associated with identification of the product of interest based on the parameter value;
• and
• receiving a second portion of the signal when a threshold condition is unsatisfied based on the probability value.

A method, comprising:

• receiving from a wireless device a signal defined in response to an input by a user of the wireless device;
• determining a keyword based on the signal;
• and
• determining, with reference to a metadata database, an identifier associated with a product based on the keyword, the identifier being different than the keyword.

A method, comprising:

• receiving a request from a user, the user defining the request in response to a transmission of at least one of an advertisement of interest or a media program of interest;
• identifying a media operator associated with the transmission of the at least one of the advertisement or the media program of interest in response to the request;
• and
• identifying the at least one of the advertisement of interest or the media program of interest based on the identifying of the media operator.

A method, comprising:

• receiving an indicator that a user request has been defined;
• receiving an observable variable value associated with the user request, the observable variable being at least one of acquired by an electronic device or defined by the electronic device;
• receiving a plurality of non-observable variable values;
• and
• determining a probability value indicating a probability that a non-observable variable from the plurality of non-observable variable values stimulated the user request, the determining includes determining based on a Bayesian network that includes the observable variable and the plurality of non-observable variable values.

A method, comprising:

• receiving from a wireless device a signal acquired at the wireless device;
• determining that the signal is substantially similar to a fingerprint signature accessed from a database that includes a plurality of fingerprint signatures;
• and
• calculating a plurality of probability values associated with a plurality of events based on a Bayesian network that includes the plurality of events and based on the determining that the signal is substantially similar to the fingerprint signature, each event from the plurality of events being associated with at least one of a location from which or a time that a request is transmitted from the wireless device.

A method, comprising:

• receiving a request for information associated with a product from a first media device, the request being triggered by a user of the first media device;
• receiving a record of a transmission sent to a second media device, the transmission being associated with at least one media operator;
• and
• determining a set of events having a probability of stimulating the user to trigger the request based on the record of the transmission.
