Delivery of high quality video in an adaptive bit rate (ABR) download session is achieved using obtained using lower quality communication paths. The method involves detecting that an ABR download session of a video is in a steady-state condition. If so a further determination is made as to whether there is sufficient pre-fetch time available to download an (N+1)th video segment of the video using at alternative connection path through a virtual WAN having a lower quality than a first connection path through the virtual WAN. If sufficient pre-fetch time is available, the (N+1)th video segment is prefetched using at least the second connection path instead of the first connection path.

A stereoscopic production solution, e.g., for live events, that provides 3D video asset distribution to multiple devices and networks is described. In some embodiments, live or recorded 3D video content may be accessible by different service providers with different subscribers/users and protocols across a network of the content provider. A first video signal corresponding to a first video feed for one eye of a viewer may be received and a second video signal corresponding to a second video feed for the second eye of the viewer may be received. The first video signal and the second video signal may be encoded. The encoded first video signal and the encoded second video signal may be transmitted independently over a network. The two video signals may be received and frame synced at an off-site location for eventual rendering to a display device.

A method for distributing High Dynamic Range (HDR) content to playback devices for displaying images where the HDR content is encoded to an HDR bitstream and the HDR bitstream is subsequently decoded by a playback device. The HDR bitstream contains auxiliary metadata packets that are based upon the processing capability of the playback device.

Embodiments described herein relate to real-time streaming of large quantities of time critical data over multiple distinct networks from a communications device. More specifically, embodiments described herein may address challenges and problems of maintaining consistent data reception quality when faced with the anomalies of a moving sender that is sending data using a relatively unstable method. This may be achieved by converting single source data into multiple data streams, placing them in transport buffers and storing them for forwarding.

A communication method and an apparatus. A terminal device receives at least one video frame from a network device. The terminal device determines a video frame parameter based on the at least one video frame. The terminal device sends the video frame parameter to the network device.

A method of processing a service in a transmitter, and including generating, by a hardware processor, a first media component and a second media component for the service; generating, by the hardware processor, signaling data for the service; time interleaving, by a time interleaver, the first media component, wherein the first media component is time-interleaved by column-wise writing actual Forward Error Correction (FEC) blocks including the first media component in a Time Interleaving (TI) memory and diagonal-wise reading the first media component in the actual FEC blocks from the TI memory, wherein one or more virtual FEC blocks are skipped during the diagonal-wise reading the written first media component, and wherein a number of the one or more virtual FEC blocks is equal to a difference between a number of the actual FEC blocks and a column number of the TI memory; generating, by a signaling generator, physical layer signaling information, wherein the physical layer signaling information includes first physical layer signaling information and second physical layer signaling information, wherein the first physical layer signaling information includes information for identifying a size of the second physical layer signaling information and wherein the second physical layer signaling information includes information for obtaining the column number of the TI memory; transmitting, by an antenna, the time-interleaved first media component, the physical layer signaling information and the signaling data through a broadcast network; and transmitting, by a network interface, the second media component to a receiver through a broadband network. Further, the signaling data transmitted through the broadcast network includes first timeline information for specifying a timeline of the first media component transmitted through the broadcast network and uniform resource location information for the second media component.

A split streaming system and method are provided in which a stream of data (that can be video, audio or textual data) is split and sent over a plurality of stream reflectors to a stream recipient. Each stream reflector performs time gradient replacement to manage the split streaming.

A transmission device according to an embodiment includes one or more processors. The processors divide a plurality of pieces of transmission data to be transmitted into first data and second data. The processors transmit the first data to a server device configured to distribute the transmission data to a reception device. The processors store the second data in storage. The processors receive, from the reception device or the server device, a request for transmission of the second data. The processors transmit the second data to the server device in accordance with the request for transmission.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A USB driver communicates I.sup.2C through a JAVA® application with a USB dongle implementing for example an ATSC 3.0 tuner, with the JAVA application simply passing I.sup.2C communication between the dongle and driver such that the driver is platform independent.

In some embodiments, a method detects an issue with broadcast tuning parameters for broadcast channels being broadcast by a broadcast system. A message is received including a set of switched digital video tuning parameters for switched digital video channels from a switched digital video system where the broadcast tuning parameters are included in the message. The method retrieves at least a portion of the broadcast tuning parameters that are received via the switched digital video system and uses the at least a portion of the broadcast tuning parameters received in the message to request a broadcast channel from the broadcast system.
