A robust, computationally-efficient and secure system is described for streaming content from a server to a client device via the Internet or another digital network. Various aspects relate to automated processes, systems and devices for securing a media stream with efficient yet effective digital cryptography. In particular, content may be transmitted in transport stream (TS) format in which all packets are encrypted (e.g., using a cipher block chain), in which control packets are exempted from encryption (e.g., using an electronic codebook), or in any other manner.

In various examples, a media stream may be received by a re-encode system that may leverage a recode engine to convert (e.g., at an interval, based on a request, etc.) an inter-frame associated with the media stream to an intra-frame. The intra-frame may be converted from the inter-frame using parameters or other information associated with and received with the media stream. The converted intra-frame may be merged into an updated segment of the media stream in place of the original inter-frame to enable storage of the updated segment—or a portion thereof—for later use.

A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, a vertical and horizontal array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines an estimated location of the wireless-enabled personal locator device.

A method for transmitting a broadcast signal, includes compressing headers of Internet Protocol (IP) packets in an IP packet stream to output a compressed IP packet stream, the compressed IP packet stream including Initialization Refresh (IR) packets, a first group of IR-dynamic packets, and compressed IP packets; extracting context information from the compressed IP packet stream, wherein when the context information is extracted only from the IR packets in the compressed IP packet stream, the IR packets are converted to a second group of IR-dynamic packets; building signaling information including the context information; and encapsulating the signaling information into one or more signaling link layer packets and the compressed IP packet stream into link layer packets that are distinct from the one or more signaling link layer packets.

Virtual Reality (VR) processing devices and methods are provided for transmitting user feedback information comprising at least one of user position information and user orientation information, receiving encoded audio-video (A/V) data, which is generated based on the transmitted user feedback information, separating the A/V data into video data and audio data corresponding to a portion of a next frame of a sequence of frames of the video data to be displayed, decoding the portion of a next frame of the video data and the corresponding audio data, providing the audio data for aural presentation and controlling the portion of the next frame of the video data to be displayed in synchronization with the corresponding audio data.

A video transmission method, system and a device includes a sending device that generates and sends a source video stream, where the source video stream includes a plurality of video data packets, each video data packet includes discard indication information, a discard priority indicated by discard indication information included in a first video data packet is higher than a discard priority indicated by discard indication information included in a second video data packet, video data in a video frame whose frame type is a non-reference B frame is encapsulated into the first video data packet, and video data in a video frame whose frame type is an I frame, a P frame, or a reference B frame is encapsulated into the second video data packet.
