| 20090187938 | Service Substitution Techniques - Service substitution techniques are described. In an implementation, a substitution table is derived that specifies one or more service substitutions to be performed for content and that specifies particular geographic locations to perform at least one service substitution. One or more communications are formed to be streamed over a packet-switched network to a client that is to perform the at least one service substitution. The one or more communications include the substitution table and the content that corresponds to the at least one service substitution. | 07-23-2009 |
| 20100251278 | MEASUREMENT AND REPORTING OF SET TOP BOX INSERTED AD IMPRESSIONS - Methods are disclosed for measuring ad impressions and receiving feedback on local ad assets inserted into a video transport stream at the set top box level. Each set top box stores the number of times an ad asset is inserted into an ad avail, along with a variety of other information relating to the playback of the ad asset. This measurement data is aggregated and sent to the ad decision service. In order to balance bandwidth usage, each set top box may report its measurement data to the ad decision service at a different time interval that is randomly selected. As it is desirable to receive the data in a timely manner, the random intervals may be confined so that all measurement data is reported within a predefined time period, such as for example over a twelve hour period. | 09-30-2010 |
| 20100251289 | ADVERTISEMENT INSERTION DECISIONS FOR SET TOP BOX MANAGEMENT OF ADVERTISEMENTS - Methods are disclosed for inserting local ad assets into a video transport stream at the set top box level. The media advertising platform of the present system works in conjunction with existing platforms, such as an advertising decision service and a media platform. The present system further includes a client resident on end user set top boxes. In general, the present system operates by pre-caching advertisements to a set top box or boxes within a household or elsewhere. Each set top box is also assigned to particular groups, based on characteristics of the user of that set top box. Group membership information is also sent to the set top box and stored. The present system sends the set top box a decision matrix based on group memberships to allow the set top box to select and insert an ad asset targeted to the specific set top box. | 09-30-2010 |
| 20110164753 | Digital Rights Management For Media Streams - This document describes techniques and apparatuses enabling application of digital rights management (DRM) to media streams. In one embodiment, three license levels are used to protect numerous television channels without undue use of computing resources. | 07-07-2011 |
