Systems and methods are described for providing viewers of streamed video content with the option to view alternative video content in which alternative tone maps are applied to respective regions of interest. In some embodiments, the streamed video content is divided into slices, and alternative tone maps are applied to respective regions of interest within the slices. When a server receives a request from a client for alternative tone mappings of different regions, slices with the appropriate mapping may be assembled on demand and delivered to the client in a single video stream. Tone mappings may be used, for example, to highlight particular objects, such as players in a sporting event captured in the streamed video content.

Systems and methods for region-of-interest tone remapping

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.

Systems and methods for selective object-of-interest zooming in streaming video

Systems and methods are described for providing viewers of adaptive bit rate (ABR) streaming video with the option to view alternative streams in which an alternative tone mapping is applied to one or more regions of interest. The availability of streams with alternative tone mappings may be identified in a media presentation description (MPD) in an MPEG-DASH system. In some embodiments, the streaming video is divided into slices, and alternative tone mappings are applied to regions of interest within the slices. When a server receives a request from a client device for alternative tone mappings of different regions, slices with the appropriate mapping may be assembled on demand and delivered to the requestor as a single video stream. Tone mappings may be used, for example, to highlight particular players in a sporting event.

Systems and methods are described for enabling a client device to request video streams with different bit depth remappings for different viewing conditions. In an embodiment, information indicating the availability of additional remapped profiles is sent in a manifest file. Alternative bit-depth remappings may be optimized for different regions of interest in the image or video content, or for different viewing conditions, such as different display technologies and different ambient illumination. Some embodiments based on the DASH protocol perform multiple depth mappings at the encoder and also perform ABR-encoding for distribution. The manifest file contains information indicating additional remapping profiles. The remapping profiles are associated with different transformation functions used to convert from a higher bit-depth to a lower bit-depth.

An implementation exits a power saving mode for fixed and periodic active periods of time to receive a separate burst transmission from a first stream during each of the corresponding active periods of time. The first stream is received at a first-stream burst data rate. The first stream includes data configured to be displayed at a first playback rate that is substantially less than the first-stream burst data rate. During the active periods of time, data is received from a second stream at a second-stream rate. The second stream includes data configured to be displayed at a second playback rate that is substantially the same as the second-stream rate. After receiving each of the burst transmissions from the first stream during the active periods of time, the power saving mode is entered for corresponding fixed and periodic power-saving periods of time while waiting for another burst from the first stream.

Method and apparatus for transmitting data

A method and system for transmitting data are described including packetizing the data, performing forward error correction (FEC) encoding on the packetized data in order to generate at least one parity packet, appending FEC information as padding to the end of payload data of the packetized data and transmitting the packetized data and the at least one parity packet. Also described are a method and system for recovering from loss of a packet including receiving a data packet, receiving at least one parity packet, buffering the received data packet, detecting packet loss, forward error correction decoding the at least one parity packet to recover from packet loss using forward error correction information extracted from the data packet and from the at least one parity packet and forwarding the recovered packet via an internal socket. Also described is a method for staggercasting.

In a network having routing elements for routing information through the network, there is provided a method for providing an ability to set up a Quality of Service contract for a videoconference session between clients. A reservation is received for a time period for the videoconference session. Configuration information, for filtering real-time traffic corresponding to the videoconference session from other traffic traversing the network, is sent to at least one of the routing elements after the time period is reserved.

Quality of service setup on a time reservation basis

A transport stream for conveying a program for a particular channel includes an auxiliary channel, which conveys multiple lower resolution programs associated with other channels. When a receiver has difficulty receiving a particular channel due to the geographical location of the receiver, the receiver tunes to a stronger signal associated with another channel and recovers a lower resolution version of the desired program from the auxiliary channel conveyed therein.

Method and apparatus for providing robust reception in a wireless communications system

A method and apparatus for performing admission control in a peer-to-peer video-on-demand system are described including determining if there is sufficient bandwidth to support leading sub-clip streaming for a new request from a video playback device, determining if there is sufficient bandwidth to admit the request without sacrificing quality of service for existing requests, accepting admission of the new request if both determining acts are positive and rejecting admission of the new request if either of the determining acts are negative. Also described is an apparatus for providing content to a video playback device in a peer-to-peer video-on-demand system including an admission control unit and a data engine component.

Data for one, or more, services is encoded using a scalable channel code and divided for transmission over N transmitters such that reception by a receiver of at least M of the transmitted signals, where M&#x3c;N, enables recovery of the data by the receiver. In other words, even if reception for any one particular transmitted signal in a defined geographical region is not guaranteed, reception of at least M of the other transmitted signals enables reception of the service(s). Thus, one, or more, services can be offered across an entire geographical area notwithstanding the existence of areas of poor, or no, reception.
