The present technology relates to a transmission device, a reception device, a transmission system, and a transmission method capable of improving transmission efficiency of subdata added to main data. A transmission device includes a frame sequence number setting unit that, on the basis of a frame number indicating an order of a subframe in a main frame, assigns to the subframe a frame sequence number indicating an order of the subframe in a frame sequence including a plurality of the subframes, and a multiplexing unit that arranges a data packet at a predetermined position in the subframe on the basis of the frame sequence number. The present technology can be applied to a CCU, for example.

A method is provided for displaying an immersive video content according to eye movement of a viewer includes the steps of detecting, using an eye tracking device, a field of view of at least one eye of the viewer, transmitting eye tracking coordinates from the detected field of view to an eye tracking processor, identifying a region on a video display corresponding to the transmitted eye tracking processor, adapting the immersive video content from a video storage device at a first resolution for a first portion of the immersive video content and a second resolution for a second portion of the immersive video content, the first resolution being higher than the second resolution, displaying the first portion of the immersive video content on the video display within a zone, and displaying the second portion of the immersive video content on the video display outside of the zone.

A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of receivers includes exploring streams broadcasted by a DVB network and streams broadcasted by an IP network and extracting services information from these streams, completing an information table, situated at the highest level in a hierarchy of services information tables, included in the service information DVB-SI transmitted by the DVB network by services information related to the IP network, and transmitting the completed information table in the streams broadcasted by the DVB network towards the receivers having two switchable receiving modules, connected respectively to a DVB and an IP services broadcasting network. The receivers are able to activate the reception of digital data of a service, equivalent to the service currently received, with a second receiving module when receiving conditions of a first receiving module are degraded.

A video optimizer receives a request to optimize a source file and stream the optimized file. The request may be accompanied by a key uniquely identifying the original source file to be optimized and an optimized version of the source file to stream to the client. The key uniquely identifies the source video file as it exists on an origin server to prevent transmission of modified source video and the optimized version of the source file by optimization parameters to ensure compatibility with the user device. The video optimizer queries a cache database in response to the received request, which contains references keys and locations of optimized source files among local caches in a cluster of video optimizers. The cache database responds indicates whether a matching optimized version of the source file exists in a local cache of a given video optimizer in the cluster.

A system and method to provide multimedia services to consumption end devices like set-top boxes and legacy phone and tablet devices that are incompatible to receive the multimedia service directly. These consumption devices interact with devices that provide multimedia service. Further, the present disclosure discloses mechanisms where an end consumption device can connect to a device like LTE connectivity device and obtain eMBMS multimedia services.

Methods and devices are provided for live broadcasting in a live broadcasting field. The method includes: displaying a first button corresponding to public live broadcasting; obtaining a public account associated with a log-in account logging in to the live broadcasting application, when a trigger operation on the first button is detected; sending a live video streaming to respective audience sides corresponding to the public account.
