Based on your request, it seems you are looking for information on how to report content or find "top" charts on the Smart YouTube TV
Since "Smart YouTube TV" is a specific third-party application for Android TV devices (often used to bypass ads and provide a leanback interface) and "617.740" appears to be a reference to a specific build version or file size metric often associated with legacy device support, I have developed a technical white paper.
Once installed, your "dumb" TV becomes a YouTube Titan:
The phrase "Smart YouTube TV 6.17 740 top" appears to combine a specific version of a popular open-source application with a request for high-quality information. Smart YouTube TV (often succeeded by SmartTube) is an independent, ad-free YouTube client designed specifically for Android-based TV boxes and smart TVs.
