Systems, methods, and devices of the various embodiments provide for header extension preservation, security, authentication, and/or protocol translation for Multipath Real-Time Transport Protocol (MPRTP). Various embodiments include methods that may be implemented in a processor of a computing device for MPRTP transmission of Real-Time Transport Protocol (RTP) packets. Various embodiments may include receiving an RTP packet in which the received RTP packet may be part of an RTP stream that may be protected using secure RTP (SRTP), and applying an authentication signature to the RTP packet to authenticate an MPRTP header extension separate from a body of the RTP packet. Various embodiments may include sending and/or receiving MPRTP subflows of an MPRTP session in which a same security context may be applied across all MPRTP subflows of the MPRTP session.

A system and method for digital collaboration where a primary node and at least one secondary node are provided connected over a local area network, at least one computing device having a display output, and a control service, where each node is connected to at least one dedicated display device, and each node having at least two image buffers each image buffer having buffered content. For each node, the selection of which buffer content of an image buffer is displayed onto the dedicated display depends on a state variable of the control service.

In accordance with an embodiment, an image forming apparatus comprises a measurement section configured to measure first environmental information of a measurement position in a first period; an acquisition section configured to acquire first external environmental information measured by a first external device; and a controller configured to estimate second environmental information of the measurement position in a second period different from the first period using the first external environmental information, and perform control to execute a maintenance operation based on the second environmental information.

An information handling system transitions security settings and/or visual image presentations based upon a user absence or user presence state detected by an infrared time of flight sensor. An operating system service monitors the state detected by the infrared time of flight sensor and other context at the information handling system to selectively apply the user absence or user presence state at the information handling system.

A system for wireless video transmission includes a video compression unit to generate a description of DCT taps, a linear mapper to generate transmission payload from the DCT taps, and a wireless transmitter to map the transmission payload into constellation points, wherein the real part and the imaginary part of each of the constellation points is a monotonic function of some of the DCT taps.
