Methods and systems for selectively skipping through media content
The disclosure provides methods and systems for skipping unwanted portions of media content based on a crowdsourcing feedback model. The media content may include television programming content, video content, and audio content. The unwanted portions of media content include, for example, television commercials, opening and closing credits. An exemplary crowdsourcing feedback model involves receiving and processing a plurality of user seek information records. These records include time markers of the media content indicating when the users started and stopped fast forwarding or when the users started and stopped moving a scrub bar to jump from one portion of the content to another. When collected, the user seek information records are used to train a machine-learning system to calculate start and stop times of unwanted portions of media content. Once the start and stop times are calculated, user devices are enabled to automatically skip these unwanted portions. |

System for addressing on-demand TV program content on TV services platform of a digital TV services provider
Video content is uploaded via the Internet to a video-on-demand (VOD) server identified by a title and a hierarchical address of categories and subcategories for categorizing the title. The VOD server converts and stores the video content at a storage address in a video content database linked to the title. The title is listed in a location of an electronic program guide (EPG) using the same categories and subcategories as in its hierarchical address. Any TV subscriber can access the EPG and navigate through its categories and subcategories to find a title for viewing on the TV. This can enable many new blogging or podcasting-like programs by popular “Hosts” to be self-published on the Internet and readily navigated for display on TV. The EPG can also store TV program addresses as bookmarks and allow them to be shared with other subscribers or with friends and contacts online by sending to their email addresses. |

Copper electrodeposition sequence for the filling of cobalt lined features
In one example, an electroplating system comprises a first bath reservoir, a second bath reservoir, a clamp, a first anode in the first bath reservoir, a second anode in the second bath reservoir, and a direct current power supply. The first bath reservoir contains a first electrolyte solution that includes an alkaline copper-complexed solution. The second bath reservoir contains a second electrolyte solution that includes an acidic copper plating solution. The direct current power supply generates a first direct current between the clamp and the first anode to electroplate a first copper layer on the cobalt layer of the wafer submerged in the first electrolyte solution. The direct current power supply then generates a second direct current between the clamp and the second anode to electroplate a second copper layer on the first copper layer of the wafer submerged in the second electrolyte solution. |
