Abstract: A processing workflow method, system, and computer program product provide the ability; to recommend alternative programming during playback of a source media program. A media program player plays the source media program to a first viewer and provides information regarding the first viewer to a recommendation engine. The recommendation engine calculates and sends the media player a list of recommended media program candidates (including identifications of the candidates) based on the information. Prior to reaching an advertising break in the source media program, the media player transmits a request (including the identifications) for an advertisement to an advertising server and in response, receives an advertisement that is played to the first viewer during the advertising break.

Abstract: A method and apparatus for navigating a media program is disclosed. Viewing data for segments of the media program are monitored and used to compile statistics that are presented to the user in a histogram, so that popular portions of the media program can be identified and navigated to. One embodiment includes a searchable transcript of the media program that is synchronized with the histogram.

Abstract: A method, system, and computer program product provide the ability to recommend, to a first viewer, alternative programming during playback of a first media program. The first media program is played. A second media program of potential interest to the user is identified. During an advertising break, an interface is presented to the user that identifies the second media program. An indication of interest in the second media program is received from the user. If the indication indicates that the user is interested in the second media program, a reference to the second media program is saved as a viewer recommendation for later playback. If not interested, additional input may be received from the user indicating why the user is not interested.

Abstract: A method and apparatus for navigating a media program via a searchable transcript of the dialog of the media program is disclosed. In one embodiment, a textural transcript of the dialog is generated, wherein the textural transcript comprising a plurality of portions wherein each portion is associated with a segment of the media program, a command is accepted to display the transcript and in response to that command, user interface data is transmitted to the client computer for presentation in a user interface, wherein the user interface comprising a concurrently presented media program player and the textural transcript.

Abstract: A method, system, apparatus, and computer program product provide the ability to bookmark a media program for subsequent viewing. A first interface is displayed and identifies a first media program. Via the first interface, a user requests that the first media program be recorded as a bookmark in a list of maintained bookmarks. The list of bookmarks is displayed. A user selects one of the bookmarks from the list and in response, the first media program is displayed to the first viewer.

Abstract: One-stage power factor correction (PFC) with output electrical isolation. Two types of PFC converters are proposed here: 1) Multi stage capacitive-switching network low voltage PFC converter and 2) two-switch soft switching PFC converters. This resulted in a near unity power factor AC-DC converter with low voltage output. The second converter uses the power switch in combination with a grounded auxiliary switch to produce soft-switching converter to operate in high switching frequencies. Due to its simplified power stage and control circuit, this converter presents a variety of benefits including better efficiency (87%), lower cost, higher reliability, increased operating frequencies into the hundreds of kilo-hertz range and low operating voltages of less than 5 volts. With PSPICE simulation and experimental results, a measured power factor of 0.99 was obtained by the single switch converter.
