Abstract: A video encoding method eliminates the need for back channel feedback by using long-term reference frames for recovering data transmission errors. A videoconferencing endpoint captures image data and designates a first frame as a long term reference (LTR) frame. Subsequent intra frames us the LTR frame for reference. When a new LTR frame is designated, subsequent frames use the newly designated LTR frame for reference only after it is determined that the newly designated LTR frame is fully operational to serve in that role.

Abstract: A lifetime value estimation of a web-based advertisement can be generated at the time of creation of a reservable listing in response to the advertisement, even when little to no information about conversion of the reservable listing is available. In a case that there is no information about a conversion time for a listing, the estimation of the lifetime value is done by calculating a real conversion rate from an advertising platform-dependent historical conversion rate, an average percentage of converted listings that converted from unreserved to reserved within a set period of days, and a scaling multiplier. Where there are relatively few conversions, the estimation of a lifetime value for the advertisement can be done using a weighted average of a campaign-level global conversion rate, which encompasses a large number of keywords that have seen conversions, and a keyword-level local conversion rate.
