A. Introduction top
Various sites capture TV News from around the world. Closed captioning texts in English and other languages are digitalized, captured, and put in this search engine. The search engine can potentially include the text of on-screen text boxes (harvested through optical character recognition), the text of transcripts, and other aspects of the broadcast.

F. Search Results top
There are two times listed for each program. The first one is the local time when it was broadcasted. Although most of the programs are broadcasted in California, there are some that come internationally. Thus, the second time is in the form of UTC.
Clicking on the video link or on the thumbnail will play the video in the player on the right. You can skip forward or backward by using the buttons in the video player.
Note: On a given search results page, when you click on a thumbnail to cue the video player you may notice a discrepancy between the thumbnail image and the frame that appears in the video player. There is a 10-second difference between the two. This is due to the closed captioning text, which always lags in timecode behind the actual video. This is not an error in the DCL's timecode structure. If you immediately click on the "skip ahead 10" link in the video player after loading the clip, you will see identical images.
This will take you to the page with the transcription of the video.
Clicking on the montage link will lead you to thumbnails taken every 10 seconds of the show. Clicking on a thumbnail will start the video at that specific time of the show.
Image Flow is a collection of montages of programs for each day. Browse by date and then program. Selecting a program will take you to the montage where you may look through thumbnails of the video for every 10 seconds. Clicking a thumbnail will take you to a new screen in which the video will be played at that timecode.
Metadata is where you can find the closed captioning along with the corresponding time stamp. Clicking on the time will play the video at that specific moment in the show. You may also bookmark the video.
The permalink will be able to take you to the page for linking the video. This bookmarks the video and will begin from the beginning of the show.
The bookmark will bring you to a page with the video which will start at a specific timecode of the show.
To bookmark a video: Simply right click (or CTRL + click if on a mac) the link "permalink" and select "Bookmark This Link." Type in a reference for the bookmark in the "name" field, then select "ok." The reference will now appear under the bookmarks menu. If using a browser other than Firefox, note that the particular steps for accessing the bookmark may differ slightly. Refer to your browser's "help" section if necessary. This bookmark will cue the video at the beginning of the clip. If you desire a bookmark for a specific time in the video, use the second option.
Bookmark a video at specific timecode: After playing the video and noting the desired timecode, click on the paper icon located at the end of each caption preview. This will open a page containing only that particular video clip. In the URL field at the top of your browser, change the last set of numbers to your desired timeocde. Note, you must convert the timecode into seconds and the number must be in ten second increments. Click enter to load the page for that specific timecode. Then select Bookmark from the browser menu bar. Select Bookmark this page. Fill in a reference in the "name" field.
There are two options for exporting: "export this page" or "export all pages." Both will lead you to the Job List page.
Upon completion of the export, you may download it and open the file using another program such as Excel. The export is text-only.

The job list will give you the list of activity done by the user. This allows you to go back to previous searches and download exports. The job list can be viewed by clicking your name at the top right corner. Displays type, start/end, query, status, message, action of activity.
