It is possible to facilitate setting of a request condition in a wireless communication system.

A capacity calculating unit calculates a wireless communication capacity in a wireless network including a plurality of wireless communication devices on the basis of information regarding a frequency bandwidth used in the wireless network. A wireless communication request condition acquiring unit acquires a request condition of a service provided in wireless communication between predetermined wireless communication devices among the plurality of wireless communication devices. A determination unit determines whether all wireless communication bearers established between the predetermined wireless communication devices satisfy the request condition of the service on the basis of the wireless communication capacity.

Creative intent input describing emotion expectations and narrative information relating to media content is received. Expected physiologically observable states relating to the media content are generated based on the creative intent input. An audiovisual content signal with the media content and media metadata comprising the physiologically observable states is provided to a playback apparatus. The audiovisual content signal causes the playback device to use physiological monitoring signals to determine, with respect to a viewer, assessed physiologically observable states relating to the media content and generate, based on the expected physiologically observable states and the assessed physiologically observable states, modified media content to be rendered to the viewer.

The disclosure provides a special effect processing method for live broadcasting. A video stream is acquired. Positions of key points of a human body contained in each frame of the video stream are obtained. For each frame, positions of target key points contained in a virtual object template are adjusted based on the positions of the key points of the human body in the frame to obtain a target virtual object corresponding to the frame. The target virtual object corresponding to the frame and the frame of the video stream are fused to generate a target video stream. The target video stream is sent to the live broadcasting client and a user client.

The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that make it possible to detect a watermark more easily. The transmission apparatus includes a generation section and a transmission section. The generation section generates watermark information for detecting a watermark. The transmission section transmits a broadcast signal including the watermark and the watermark information. When the transmission apparatus is provided, it enables the reception apparatus at a receiving end to detect the watermark more easily. The present technology is applicable, for example, to a transmission system including the transmission apparatus and the reception apparatus.

Systems and methods are described for enabling a consumer of streaming video to obtain different views of the video, such as zoomed views of one or more objects of interest. In an exemplary embodiment, a client device receives an original video stream along with data identifying objects of interest and their spatial locations within the original video. In one embodiment, in response to user selection of an object of interest, the client device switches to display of a cropped and scaled version of the original video to present a zoomed video of the object of interest. The zoomed video tracks the selected object even as the position of the selected object changes with respect to the original video. In some embodiments, the object of interest and the appropriate zoom factor are both selected with a single expanding-pinch gesture on a touch screen.

A method and system are described wherein a terminal sends, to a server, a video request message that includes an identifier of a virtual reality (VR) video. The VR video comprises N sub-bitstreams. The terminal receives a video response message sent by the server. The video response message indicates multicast addresses respectively corresponding to the N sub-bitstreams, and the terminal determines a target sub-bitstream based on a current field of view of a user, and obtains the target sub-bitstream based on a multicast address corresponding to the target sub-bitstream. The multicast address is one of the multicast addresses, and the target sub-bitstream comprises at least one sub-bitstream of the N sub-bitstreams.

The disclosure provides for use of steganographically-encoded data as a basis to control content modification. A server could determine through a fingerprint comparison that a portion of media content on a channel being rendered by a content presentation device matches at least one modifiable-content segment, such as at least one replaceable ad. The server could then use watermark data encoded in the media content of the channel as a basis to determine an actual identity of a modifiable-content segment present on the channel, so as to then control content modification.

A method, system and product for compressing videos. The method comprising: obtaining a video that comprises a sequence of video frames, wherein the sequence of video frames comprises at least a first frame and a second frame, wherein the first frame is ordered before the second frame in the sequence of video frames; determining to preserve the first frame in its entirety; and in response to a determination to utilize a partial frame instead of the second frame: cropping the second frame to determine a cropped frame, wherein the cropped frame is smaller in at least one dimension than the second frame, wherein said cropping is based on an anchor location; whereby an alternative video can be constructed using the first frame and the cropped frame, wherein the alternative video does not include a remainder portion of the second frame in an explicit manner.

Multiple different versions of media content are contained in a single package of audio-video media content, using compression algorithms that reduce storage and bandwidth required for storing multiple full-resolution versions of the media. Portions of individual frames are replaced during playback so that only the pixels that differ between versions need to be stored.

A proxy device may organize a set of local devices as members of a union. The proxy device may create a set of virtual peripheral devices. The set of virtual peripheral devices may represent a set of physical peripheral devices connected to the set of local devices. The proxy device may communicate the set of virtual peripheral devices to a remote device.
