Note：
The following fees are based on the billing rules of TIW. When TIW is used, other cloud products are often used as well. For specific usage restrictions and billing rules, please refer to the corresponding product documentation.
1. IM: TIW by default uses IM for the transmission of interactive signaling, such as graffiti. However, you may choose to use the Custom Signaling Channel. If you choose to use IM, please refer to Usage Restriction for usage limits and Pricing Details for billing particulars.
2. TRTC: In-class recording of TIW may require accessing the TRTC room where whiteboard and audio-visual interactions are mixed and recorded. Furthermore, whiteboard streaming pushes the whiteboard visuals to the TRTC room.
3. COS: Post-transcoding, TIW uploads the documents and recorded videos to COS. For details regarding the billing rules of COS, please refer to Billing Overview.
4. CDN: For scenarios with widespread distribution and download of the same video/document, to decrease access latency and increase availability, it is recommended to accelerate access to COS using CDN. For details regarding CDN billing, please refer to Billing Overview.
5. CI: The New Transcoding Solution utilizes document preview capabilities of CI.
