Abstract: A system or method selects among multiple tuners to tune a particular channel. A request is received to tune a first channel. In response to this request, a first tuner is assigned to tune the first channel. A request is received to tune a second channel. If the program tuned by the first tuner is not being recorded, the first tuner is assigned to tune the second channel. If the program tuned by the first tuner is being recorded, the second tuner is assigned to tune the second channel.

Abstract: Set top box logs are received from a television provider and processed to identify channel tunes and channel tune times. The channel tunes and channel tune times of the log data can be compared to expected air times of television advertisements on channels, and an impression values, e.g., projected viewers, can be generated for each television advertisement.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for panel surveys. In one aspect, a method include accessing television history data for viewing devices associated with panelists and that describes, for each viewing device, television advertisements that were presented by use of the viewing device; a proper subset of panelists are selected based on the determinations of television advertisements that were presented and television advertisements that were not presented by use of the viewing device associated with the panelists, and for each of the selected panelists, a survey for the panelist is generated, the survey including one or more questions, each of the questions having been selected based on the television advertisements that were presented and television advertisements that were not presented by use of the viewing device associated with the panelist.

Abstract: Reporting data related to content processing devices, e.g., television devices, are processed to identify channel tunes and corresponding tune times of the content processing devices. Automatically generated channel tunes based on the corresponding tune times are identified. Content items that are aired during a time period defined by the corresponding tune times can be adjusted.

Abstract: Accelerated channel change (ACC) strategies are described for supplying a client module with media information by transitioning between a first delivery of media information provided by first delivery functionality and a second delivery of media information provided by second delivery functionality without exceeding prescribed data rate limitations. The first delivery functionality can represent server-based functionality for delivering a unicast stream of media information at a data rate (or maximum data rate) of some excess amount over the nominal rate of delivery, starting at a selected location within the media information. The second delivery functionality can represent any functionality for delivering the media information at the data rate (or maximum data rate) of the nominal rate of delivery. A join interval separates the first delivery at the excess rate and the second delivery at the nominal rate.

Abstract: Set top box logs are received from a television provider and processed to compensate for broadcast latency and generate normalized log data, e.g., log data that are indexed to a relative time. Channel tunes and the channel tune times of the normalized log data can be compared to expected air times of television advertisements on channels, and an impression values, e.g., projected viewers, can be generated for each television advertisement.
