摘要： The present invention is directed to fine granular coding technique that includes both quality and temporal scalability. This is accomplished by utilizing a hybrid temporal/SNR scalability structure that is readily adaptable to fine granular coding techniques. In one example of this structure, temporal enhancement frames and FGS enhancement frames are included in a single enhancement layer. In another example, two distinct enhancement layers are used to achieve the hybrid temporal-SNR scalability. The two layers include a temporal scalability layer to achieve the temporal enhancement for the base-layer (i.e., better motion), while an FGS layer is used to improve the quality SNR of the base-layer and/or the temporal-scalability enhancement layer.

摘要： Improved efficiency in transmission of FGS encoded video data is achieved by reducing the transmission of overhead information items necessary to decode the received video data. After establishing an initial or first set of criteria for selectively enhancing areas within an image, each subsequent transmission frame includes an indicator that informs a receiving system to decode the current frame using the previously established criteria. The initial criteria include shift factor values specifying selectively enhanced areas of an image; position, displacement vector, size and enhancement factor for at least one area of interest with in an image; and known fixed values contained at both the transmitting and receiving systems.

摘要： A video coding technique having motion compensation within a fine granular scalable coded enhancement layer. In one embodiment, the video coding technique involves a two-loop prediction-based enhancement layer including non-motion-predicted enhancement layer I- and P-frames and motion-predicted enhancement layer B-frames. The motion-predicted enhancement layer B-frames are computed using: 1) motion-prediction from two temporally adjacent differential I- and P- or P- and P-frame residuals, and 2) the differential B-frame residuals obtained by subtracting the decoded base layer B-frame residuals from the original base layer B-frame residuals. In a second embodiment, the enhancement layer further includes motion-predicted enhancement layer P-frames. The motion-predicted enhancement layer P-frames are computed using: 1) motion-prediction from a temporally adjacent differential I- or P-frame residual, and 2) the differential P-frame residual obtained by subtracting the decoded base layer P-frame residual from the original base layer P-frame residual.

摘要： The present invention is directed to rearranging the transmission order of the enhancement-layer frames. By making the display and transmission order of the enhancement layer frames identical, a frame memory is not required on the decoder-side to hold the enhancement-layer frame until being displayed since the display can take place immediately after the decoding. Reducing the amount of memory is desirable for mobile applications or other low-power consumption devices.

摘要： A system and method is provided for combining advanced data partitioning and fine granularity scalability in the transmission of digital video signals. A partition unit 440 located in a base layer encoding unit 410 of a video encoder 400 partitions a base layer bit stream 310, 320 into a base layer first partition bit stream 310 and a base layer second partition bit stream 320. Each of the two base layer bit streams 310, 320 may be output directly or may be encoded before output. The two base layer bit streams 310, 320 may be encoded with a scalable encoder unit 442 or with a non-scalable encoder unit 444. Fine granularity scalability is improved by providing an extended base layer bit rate. The bit rate range for advanced data partitioning is also extended. The invention provides improved video coding efficiency, complexity scalability, and spatial scalability.

摘要： Multiple Description Coding (MDC) has been shown to be an effective technique for robust transmission of video data over networks including wireless systems and the Internet. A method is provided where the video signal (20) is interlaced and split into multiple streams before being encoded and transmitted over separate transmission channels (308, 310). At a receiver (320) side, de-interlacing algorithms may be applied and the streams are regrouped to form the original video signal (20). The use of interlacing and deinterlacing techniques improve the robustness of video transmission without having to modify existing equipment.
摘要翻译：多描述编码（MDC）已经被证明是用于通过包括无线系统和因特网在内的网络强大地传输视频数据的有效技术。提供了一种方法，其中视频信号（20）在被编码之前被隔行扫描并分离成多个流，并通过单独的传输信道（308,310）传输。在接收机（320）侧，可以应用去隔行算法，并且重新分组流以形成原始视频信号（20）。使用交错和去隔行扫描技术可以提高视频传输的鲁棒性，而无需修改现有的设备。
