Abstract
Disclosed herein are systems and methods for reducing the amount of data associated with user events. The systems and methods are particularly applicable to cable TV, satellite TV, and other networks where user event data (e.g., clickstream) must be sent from customer premises equipment (CPE) to centralized servers and the data transmission channel is narrow. In various exemplary embodiments, CPE such as television set-top boxes may reduce requirements for data storage and network bandwidth by replacing portions of channel-number/timestamp streams with abbreviated codes representing common meta-events such as “channel surfing events” and “previous channel events.” The original channel-number/timestamp streams can be reconstituted on centralized servers. Other common sequences of events, including those involving activation of other buttons on remote controls (i.e., buttons not related to changing channels), keyboard keys, mouse pointing device controls, and the like may constitute meta-events and be similarly replaced by abbreviated codes.
