The present invention relates to a data transmission device and reception device in a wireless AV system. Disclosed in the present specification is a wireless data transmission device comprising: a processor for generating a compressed bitstream by encoding media data; and a communication unit for segmenting the compressed bitstream, mapping the segmentation results to MSDUs, generating an MPDU frame sequentially including a MAC header, a frame body, and an FCS associated with the MAC header in order to transmit the MSDUs, generating a PPDU frame sequentially, which includes a preamble to which at least a portion of the MAC header is mapped, at least one PPDU to which the frame body and the FCS are mapped, and a TRN field, and transmitting the PPDU frame through a wireless channel. A data transmission rate can be improved through a reduction in overhead information.

A satellite reception assembly may include a housing configured to support receipt and handling of a plurality of satellite signals. The housing may include circuitry incorporating integrated stacking architecture for supporting and/or providing channel and/or band stacking whereby particular channels or bands, from multiple satellite signals that are received via the satellite reception assembly, may be combined onto a single output signal that may be communicated from the satellite reception assembly to a gateway device for concurrent distribution thereby to a plurality of client devices serviced by the gateway device.

Systems and methods for establishing secure remote connections to media devices establish a secure shell (SSH) connection between two machines which are located in two different private networks, such as between a remote debugging computer and a receiving device. The receiving device has a persistent outbound connection with a message server. The remote debugging computer connects to a relay manager and obtains a relay instance IP address and port. The relay manager then forwards the relay instance IP address and port to the receiving device via the message server. After receiving the connection request from the message server, the receiving device connects to the relay instance IP and port and waits for the input data. The remote debugging computer performs an SSH handshake and the receiving device directly authenticates the SSH connection.

The present disclosure provides a technical scheme for transmitting video streams in WiFi mesh networks, including a method for transmitting multicast video in an access points in a WiFi mesh network, wherein the method includes: receiving a video stream and determining the node(s) to which the video stream needs to be transmitted, wherein the video stream includes a multicast address; determining dynamically a transmission mode of the video stream and transmitting corresponding video stream to multiple stations using the transmission mode when the nodes are the multiple stations corresponding to the multicast address; transmitting corresponding video stream to a next access point using unicast mode when the node is the next access point.

A method for co-hosting and an electronic device are disclosed. In the method, a co-hosting establishment instruction is acquired; configuration information of the first live streaming client is acquired in response to the co-hosting establishment instruction; first communication protocol information corresponding to a co-hosting process is acquired from the configuration information; and co-hosting with a second live streaming client is established based on the first communication protocol information. The co-hosting process is a general process in different types of co-hosting services, and includes a co-hosting establishment process.

Methods, systems, and machine-readable media for adapting content composites to device operations of an endpoint media device are disclosed. Blockchain data associated with a blockchain address may be processed by one or more processing devices. The blockchain data and/or the blockchain address may be mapped by the one or more processing devices to a first endpoint media device. Based at least in part on the blockchain data, a first content composite may be identified by one or more processing devices for delivery from a content provider system via one or more networks to the first endpoint media device. Transmission of the first content composite may be caused where, consequent to delivery of the first content composite to the first endpoint media device, the first endpoint media device or a second endpoint media device performs at least one operation relating to the first content composite.
