摘要： The construction method of NALU (Network Abstraction Layer Unit) for IPv6 label switching and its using algorithms of video encoding, QoS control, and decoding are provided. According to an embodiment of the present invention, the NALU format is composed of the NALH (Network Abstraction Layer Header) including the label and the NAL (Network Ab¬straction Layer) payload. Here, the label is determined based on layer information which is combination of a spatial scalable level, a temporal scalable level, and a quality scalable level of the encoded data. The decoder uses the label to decide which one of multiple decoding modules is used to decode the current NAL payload. Moreover, the label can be included in the packet header so that the MANE (Media Aware Network Element) can use the label to decide whether to forward the packet or drop it. For example, the label in the packet header can be used for QoS control of video service by using the flow label field in IPv6 packet header. The IPv6 router can identify priority of the video packet by using the 20 bit long flow label, into which the label in NALH can be inserted. According to the embodiment, the MANE assumed in the MPEG and JVT (Joint Video Team) can be implemented effectively.

摘要： In a cloud gaming system or other remote video streaming system, a client device and a server coordinate to introduce an adjustable delay in the frame start timing in the frame rendering pipeline at the server to reducing vertical synchronization (VSYNC) presentation latency, and thus reduce overall frame latency. In implementations, the coordination between the client device and the server includes the client device observing the current VSYNC presentation latencies in recently processed video frames reporting this observed VSYNC presentation latency to the server. The server uses this feedback to determine a frame start delay that is then used to introduce a frame start shift for an upcoming frame and subsequent frames, thereby shifting the server rendering and encoding pipeline back so that the resulting video frames are made available to present at the client device closer to their respective VSYNC signal assertions.

摘要： A transmission apparatus, a transmission method, and a program that can reduce the number of times that useless transmission of image data is performed due to a failure in reception of image data indicating a reference destination. A transmission failure likelihood data management section checks the likelihood of a failure in transmission of first image data. Second image is an image rendered in a frame buffer for the first time after a timing when a predetermined time has elapsed since the transmission of the first image data. An encoding processing section controls whether or not to generate second image data requiring no reference destination, depending on the likelihood of the failure in the transmission of the first image data at a timing of encoding the second image.

摘要： A system and method for transcoding data. The system includes an adaptive transcoder that transcodes data to produce transcoded data having a first data rate, and transmits the transcoded data to a client device. The adaptive transcoder receives a quality signal. The adaptive transcoder transcodes the data at a second data rate in response to the adaptive transcoder determining that the quality signal indicates that the first data rate is deficient based on at least one of processing capabilities of the client device and network connection capabilities between the adaptive transcoder and the client device.

摘要： Disclosed is a data transmission system having a transmitter and a receiver. The transmitter encodes external input signals to acquire coded transmission data transmitted in multiple paths with different frequency band, and then transmits them to respective receiver; and the receiver performs data fusion on the received transmission signals to acquire coded received data, and decodes it to acquire and output the decoded data. In conclusion, since the received signals are split into a plurality of transmission signals of different frequency bands by the transmitter and the signals are fused in the receiver, the signals are not susceptible to the same frequency interference during transmission, improving the anti-interference of the data transmission system, realizing high-reliability transmission at low cost or in a complex wireless environment, also expanding the applications of the data transmission system.

摘要： A video encoding device (e.g., a wireless transmit/receive unit (WTRU)) may transmit an encoded frame with a frame sequence number using a transmission protocol. The video encoding device, an application on the video encoding device, and/or a protocol layer on the encoding device may detect a packet loss by receiving an error notification. The packet loss may be detected at the MAC layer. The packet loss may be signaled using spoofed packets, such as a spoofed NAM packet, a spoofed XR packet, or a spoofed ACK packet. A lost packet may be retransmitted at the MAC layer (e.g., by the encoding device or another device on the wireless path). Packet loss detection may be performed in uplink operations and/or downlink operations, and/or may be performed in video gaining applications via the cloud. The video encoding device may generate and send a second encoded frame based on the error notification.

摘要： In various examples, a deep neural network (DNN) based pre-filter for content streaming applications is used to dynamically adapt scene entropy (e.g., complexity) in response to changing network or system conditions of an end-user device. For example, where network and/or system performance issues or degradation are identified, the DNN may be implemented as a frame pre-filter to reduce the complexity or entropy of the frame prior to streaming—thereby allowing the frame to be streamed at a reduced bit rate without requiring a change in resolution. The DNN-based pre-filter may be tuned to maintain image detail along object, boundary, and/or surface edges such that scene navigation—such as by a user participating in an instance of an application—may be easier and more natural to the user.
