Abstract: Certain aspects of the disclosure relates to a system and method of performing virtual media redirection. The system includes a baseboard management controller (BMC) connected to a host computing device through a communication interface, and a client computing device communicatively connected to the BMC through a network. In operation, the BMC emulates a virtual media for a media device, and establishes a virtual media connection to the client computing device through the network. Then the BMC stores the data from the media device in a host cache at the BMC and in a client cache at the client computing device by sectors. When the BMC receives a request from the host computing device through the communication interface to retrieve sectors from the media device, the BMC redirects the sectors being requested to the host computing device depending on where the requested sectors are stored.

Abstract: Aspects of the disclosure relate to systems and methods of recording video frames from a computing device by a management device. The management device may receive video frames from the computing device. In response to receiving the video frames, the management device may process the video frames in a first-in-first out (FIFO) order to generate processed video frames according to a recording method, store the processed video frames in the FIFO order in the memory of the management device, and then release the memory occupied by some of the processed video frames in the FIFO order based on a memory releasing condition defined by the recording method to store the processed video frame. The memory releasing condition is determined by multiple optimized parameters of the recording method. The recording method may be a sliding window recording method, a multiple-window fixed size recording method, or a multiple-window dynamic size recording method.

Abstract: The disclosure relates to system event assisted live video capture. A baseboard management controller (BMC) allocates, in its available memory space of the memory, a first video block and a first node having a video block pointer and a next node pointer, and assigns the video block pointer of the first node to indicate the first video block. The BMC captures video frames of the host computer, and stores frame data and a timestamp generated from each frame in the first video block. When the first video block is full, the BMC allocates a second video block and a second node, and assigns the next node pointer of the first block to indicate the second node, and the video block pointer of the second node to indicate the second video block. The BMC then stores the frame data and the timestamp in the second video block.
