The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that permit efficient transfer of time and other information. The transmission device generates a physical layer frame having preambles and a payload that includes, in the preamble, time information representing time of a given position in a stream of physical layer frames and transmits the physical layer frame. The reception device receives the physical layer frame and performs processes using time information. The present technology is applicable, for example, to IP packet broadcasting.

Example methods and apparatus to detect audio engineering problems using identification of isolated watermarks are disclosed herein. Disclosed example methods include identifying, by executing an instruction with a processor, isolated watermarks in a first set of detected watermarks obtained from first media monitored at a first site. Disclosed example methods further include determining, by executing an instruction with the processor, a problem has been detected with the first media associated with the first set of detected watermarks in response to a first number of isolated watermarks identified in the first set of detected watermarks satisfying a first threshold.

A transmitting method stores data making up a coded stream into a predetermined data unit and transmits the stored data in the predetermined data unit. The transmitting method further generates presentation time information indicating a presentation time of the predetermined data unit, based on reference time information received from an external source; and transmits the predetermined data unit, first control information which includes the generated presentation time information, and second control information which includes leap second information indicating whether or not the presentation time information is a time that is before a leap second adjustment. A receiving method receives the predetermined data unit, first control information, and second control information; and reproduces the received predetermined data unit based on the first and second control information that are received.

Techniques are disclosed for managing delivery of content and tracking the same via audio cues. For example, a client computing device may monitor ambient sound for audio that matches audio sampled from broadcast content. In response to detecting matching audio, the client computing device transmits tracking data to a centralized content server. The content server records the tracking information and evaluates whether the matching audio was detected within a geographic area associated with the broadcast content. If so, the content server executes additional actions including transmitting supplemental content to the client computing device and/or updating summary level metrics that indicate receptions of broadcast content within target geographic locations.

In one aspect, a method includes (i) accessing broadcast-schedule data associated with a channel; (ii) using the accessed broadcast-schedule data to identify an upcoming content-modification opportunity on the channel; and (iii) responsive to identifying the upcoming content-modification opportunity on the channel, performing an action to facilitate performing a content-modification operation related to the identified upcoming content-modification opportunity on the channel, wherein performing the action comprises causing in-band message data to be inserted into at least a portion of a content segment that is being transmitted by a content-distribution system on the channel.

An electronic apparatus includes a communication interface, a broadcasting signal receiver to receive a broadcasting signal, and a processor configured to receive first broadcasting schedule information including channel names and broadcasting program information for a plurality of first broadcasting channels from a server through the communication interface, obtain second broadcasting schedule information including channel names and broadcasting program information for a plurality of second broadcasting channels from the broadcasting signal, match the plurality of first broadcasting channels with the plurality of second broadcasting channels, and generate a channel matching table by matching the plurality of first broadcasting channels with the plurality of second broadcasting channels by comparing at least one of the channel names or the broadcasting program information included in the first broadcasting schedule information with at least one of the channel names or the broadcasting program information included in the second broadcasting schedule information.

A system and method for determining a similarity measure between a first network broadcast time segment and a second network broadcast time segment. The method includes generating first training data comprising groupings of similar broadcast networks and groupings of dissimilar broadcast networks, extracting second training data comprising audience data and genre data for time segments of network broadcasts, and training an encoder neural network based on the first and second training data. The method includes executing the trained neural network with input data comprising the first network broadcast time segment and determining a similarity measure relative to the second network broadcast time segment.
