A method for facilitating targeted secondary content delivery to a user is envisaged. The primary content is broadcast on a television accessible to a user, followed by targeted delivery of relevant secondary content onto a handheld device of the user. The secondary content deemed as being relevant to the primary content is delivered in an unobtrusive manner without altering the viewing experience of the primary content, only after verification of the viewership of the primary content. The secondary content deemed as relevant to the primary content is transmitted to a handheld device accessible to the user thereby not altering the viewing experience corresponding to the viewing of the primary content on the television. The secondary content is delivered to the handheld device via electromagnetic waves, preferably radio waves without necessitating an active internet connection for the handheld device, and without necessitating the user to remain logged-on to the handheld device.

Determining effect of changes in parameters may include, during a time interval, rotating from setting a first parameter to a first value for a first time period, to setting the first parameter to a second value for a second time period such that the time interval includes multiple first time periods with the first parameter set to the first value sequenced with multiple second time periods with the first parameter set to the second value; obtaining, for the time interval, a first set of ratings corresponding to the first time periods and a second set of ratings corresponding to the second time periods; averaging, for the time interval, the first set of ratings to a first average rating and the second set of ratings to a second average rating; and correlating the first average rating to the first value and the second average rating to the second value.

Disclosed are a method, a device and a system of generation of a modified digital media file based on a encoding of a digital media file with a decodable data such that the decodable data is indistinguishable through a human ear from a primary audio stream. In one embodiment, a method of an audio encoding system includes validating a user of the audio encoding system as a publisher, associating a response action to a message of the user, the response action is at least one of a call-back action, a web-form action, and a resource-page redirect action using a processor and a memory, generating a unique identifier through a hash function applied to the response action associated with the message of the user, encoding a digital media file associated with the message with a decodable data using the unique identifier such that the decodable data is indistinguishable from a primary audio stream through a human ear, and generating a modified digital media file associated with the digital media file based on the encoding of the message with the decodable data such that the decodable data is indistinguishable from a primary audio stream through the human ear.

A method and apparatus for recognizing and synchronizing to in-band data at a multimedia device is provided. A content stream includes in-band data. The in-band data is processed and in-band data pattern data associated with the content stream are created. Metadata are attached to the event identification data. The event identification data are provided to multimedia devices which receive broadcasted multimedia content streams containing video programs with in-band data. The in-band data are processed and compared to the event identification data. If a match occurs, the multimedia device uses the metadata to perform specified actions.

Example methods and apparatus to audio watermarking and watermark detection and extraction are disclosed herein. An example apparatus disclosed herein includes memory, computer readable instructions, and processor circuitry to execute the computer readable instructions to at least detect a first symbol, a second symbol, a third symbol, and a fourth symbol sequentially in encoded audio samples, determine whether the first symbol is a synchronization symbol, in response to a determination that the first symbol is a synchronization symbol, determine that the first symbol and the third symbol are associated with a first message and the second symbol and the fourth symbol are associated with a second message, and output at least one of the first message or the second message.

The present technology relates to a reception device, a transmission device, and a data processing method with which it becomes possible to operate digital television broadcasting more flexibly.

A reception device receives a broadcast signal transmitted by frequency division multiplexing (FDM) and processes, on the basis of control information existence information that is information included in first control information, which is acquired from the broadcast signal and is control information in a physical layer, and that indicates existence/non-existence of second control information that is control information in an upper layer of the physical layer, the second control information transmitted in each hierarchy. The present technology can be applied, for example, to a receiver that can receive digital television broadcasting.
