It does not count the number of times the specified phrase is found in the captions. All queries run by the Stanford Cable TV Analyzer, regardless of the filters used, compute the time spanned by video segments that match the specified filters. If textwindow is set to 0, then the time when the word is said is used; in this case, users should be mindful that longer text phrases may contribute more time per instance than shorter phrases.
Since text filters like all other filters are used to select video segments, they can be combined with all other filters in queries. Combining text and face filters e. For example, the following graph computes the time that Hillary Clinton is on screen AND the word "email" is spoken. We observe that word "email" is sometimes written as "e mail" in the captions, so the text search filter matches both "email" or "e mail".
Observe that the above graph computes the amount of time where Ms. Clinton is on screen AND the word "email" is spoken, but this query does not mean that the word "email" was spoken by Ms. It is possible the speaker was another person on screen or even an off-screen voice. At this time the Stanford Cable TV Analyzer does not provide the ability to identify who spoke the words in the text caption.
In many situations it is useful to view examples of video clips that pass a query's filters. For example, you might wish to inspect the matching video clips to get of sense of whether automated face identification is robustly recognizing the person specified in the query.
Another common task is to view selected clips when debugging a more complex query to ensure the query is selecting the types of videos intended.
When viewing a graphs on the main Stanford Cable TV News Analyzer site, clicking on the graph will display a random selection of video clips that matched query's filters at that point in time. You can further investigate these results by playing the video clips as well as viewing their captions. These thumbnails serve as a good reminder that a person can appear on screen in many different ways: as a guest on a show, in B-roll footage, or as a static image used as part of an infographic.
You've now seen a few basic examples of writing screen time queries. We now invite you to try creating more of your own! We're excited to see what analyzes are possible. To learn more about more advanced query features not discussed in this tutorial, please take a look at the advanced queries page. You may also want to browse the dataset page to learn about what people and tags available for use in queries.
Getting Started The Stanford Cable TV Analyzer enables you to write queries that compute the amount of time people appear and the amount of time words are heard in cable TV news. Computing the Screen Time of Individuals Writing a query using the Stanford Cable TV Analyzer involves specifying filters that determine what video segments to include in a screen time computation.
Usually the new version fixes a couple of bugs, but it also adds drivers for any new Amlogic chipsets that have come out since the last version. That said, there are some legitimate reasons for wanting to use an older version of the tool. I recommend downloading the latest version version 3. Once you download the version you want, extract it to a temporary directory on your PC. Once the files are extracted, navigate to that directory and click on the setup exe file to get started.
It allowed me to leave my Android TV box where it was and connect the cable comfortably to my laptop. No matter which cable you use. Once it powers up, your PC will detect it as a new device and a pop-up box will appear in the lower right-hand corner of the screen, just above the clock.
Installing the Amlogic USB Burning Tool is fairly straightforward, but there are a few potential hiccups to watch out for.
If you have a different version of Windows, or are installing this on a Mac, then your screens will probably look different than mine. The installation process is split into two sections: the burning tool itself and the drivers for your Android TV box. Start by clicking on the Setup. A small pop-up window will appear asking you to choose a default language for the tool. The first installation window gives you the standard disclaimer that you should exit any other program.
Click Next to continue. Unless you have a reason to change it, I recommend leaving it at the default location. By default, it will create a folder titled Amlogic. However, if you have all of your Android apps in one specific folder, you can change that here. I normally leave this un-checked. The installation program will ask you to verify your settings one last time.
If everything looks correct, click Install to complete the process. The second part of the installation will load the correct drivers for your device. This will allow your PC to actually communicate with your TV box.
Once the drivers are correctly installed, the original setup window will change to the image you see above. Back in the first step of the installation process, you selected the default language for the app. However, if you click the wrong button, or if you have an older version of the Amlogic USB Burning Tool, you may be shocked to see your screen like this:.
Thankfully, changing the language is easy. The second word will allow you change the Language. Because of that, we need to run the burning tool as the Administrator. Depending on your version of Windows, you may be able to click Run As Administrator directly, or you may need to click on the More menu as you see above. Once you click on it, the screen should change and all your windows will vanish temporarily.
A new pop-up box will ask you to confirm that you want to run this program. Most operating systems have them Windows, iPhones, Android, etc. The trick is that every device is slightly different and there are several ways to get into recovery mode.
