Systems and methods for reducing latency on a collaborative platform are provided. The collaborative platform involves a display, a moderator device, one or more member devices, and a receiver in communication with the display, the moderator device, and the one or more member devices. To reduce latency of the collaborative platform, the receiver generates an overlay image based on user input received from the display, as well as user type of the user input, generates an overlaid image based on the overlay image, and transmits the overlaid image for display, while a collaboration application generates new real image(s) based on the user input for display. The overlaid image generated may be indicative of actual user input as well as predicted user input using extrapolation and/or machine learning.

A connecting method, apparatus of a screen transmission device based on NFC, and a computer device are provided. The connecting method of the screen transmission device based on NFC includes touching an NFC tag, and identifying whether the NFC tag contains network information of the screen transmission device; and when the NFC tag contains the network information of the screen transmission device, acquiring the network information, and connecting with the screen transmission device according to the network information.

Systems and methods for authorizing operations associated with blocked media assets using two-factor authentication. In some aspects, a media guidance application (e.g., executed by a set-top box or other user equipment used to store and display media assets) prompts a user for a password (e.g., a personal information number) in order to unlock the content for viewing. In response to receiving a second request from the user to perform an operation related to the media asset (e.g., delete), the media guidance application prompts the user for an additional factor confirming his or her identity, consistent with two-factor authentication protocol. If the user's identity is authenticated as a user that has authority to perform the operation related to the media asset (e.g., delete the stored media asset), the media guidance application performs the operation related to the media asset (e.g., deletes the media asset).

A media content storage and delivery system, and related operating methods are presented here. A disclosed method of delivering user-provided content that is linked to on-demand media content involves: causing playback of on-demand media content at a first presentation device; receiving uploaded media content, wherein uploading of the uploaded media content is initiated during playback of the on-demand media content at the first presentation device; and linking the uploaded media content with the on-demand media content. After performing the linking, the method causes playback of the on-demand media content at a second presentation device, and causes playback of the uploaded media content after playback of the on-demand media content at the second presentation device, or after pausing playback of the on-demand media content at the second presentation device.
