Abstract: A single progressive 1080P60 side-by-side 3D video or a single progressive 1080P60 2D video is captured for transmission to interlaced receivers such as a legacy 1080i capable video receiver. A video transmitter splits the captured 1080P60 video into a plurality of even-indexed line pictures and odd-indexed line pictures. Lines of the plurality of even-indexed line pictures and odd-indexed line pictures are reassembled to generate two interlaced video sequences such as two 1080i video sequences. The video transmitter compresses the generated two 1080i video sequences, respectively, utilizing different compression algorithms, for example. Pictures that originate from the same one of the plurality of pictures in the captured 1080P60 video may be synchronized for a progressive display at the legacy 1080i capable video receiver. The legacy 1080i capable video receiver may decode the synchronized pictures from the video transmitter so as to restore the captured 1080P60 video for display in progressive format.

Abstract: In a signal processing system, a programming system and method for a video network are provided. An event may trigger an RDMA controller to execute current instructions in a register update list. The triggering event may be a start-of-field signal from a live source or an end-of-frame signal. The current instructions may be used to modify the mode of operation of at least one of the network elements in the video network. The modification to the mode of operation may depend on whether the current video field is top field originated or bottom field originated. An interrupt may be used to initiate an interrupt handler that generates at least one new instruction and that updates the new instructions in the register update list. When a trigger occurs prior to an update of the register update list, the RDMA controller may execute the current instructions in the register update list.

In an embodiment of the present invention, the data structure contains all the information associated with the display of a video field, regardless of whether certain data changes from one field to the next.

In an embodiment of the present invention, there may be several layers of graphics below the video layer, and several graphics layers above the video layer. The top graphics layers may be blended into one top graphics layer, and the bottom graphics layers may be blended into one bottom graphics layer. The top and bottom graphics layers may be then blended into one graphics layer and combined with the video layer.

The IC may be operable to determine whether to scale the 3D video data before the 3D video data is captured to memory or after the captured 3D video data is retrieved from memory, and selectively interconnect one or more of the devices based on the determination. The selective interconnection may be based on input and output formats of the 3D video data, and on a scaling factor. The input format may be a left-and-right (L/R) format or an over-and-under (O/U) format. Similarly, the output format may be a L/R format or an O/U format. The selective interconnection may be based on input and output pixel rates of the 3D video data. Moreover, the selective interconnection may be determined on a picture-by-picture basis.

The video data from one or more of those sources may comprise three-dimensional (3D) video data. The video data from each source may be stored in corresponding different areas in memory during a capture time for a single picture. Each of the different areas in memory may correspond to a different window of multiple windows in an output video picture. The video data from each source may be stored in memory in a 2D format or in a 3D format, based on a format of the output video picture. When a 3D format is to be used, left-eye and right-eye information may be stored in different portions of memory. The video data may be read from memory to a single buffer during a feed time for a single picture.

The high-resolution may comprise a resolution that may be greater than half resolution. The first single frame in the SVC base layer may be used as a base-layer reference for the second single frame in the SVC enhancement layer for inter-layer prediction of spatial scalable coding.

Abstract: A system and method that abstracts an interrupt from a group of interrupts, which may occur in a module, to call another module. Abstracting one interrupt from a group of interrupts allows the called module to deal with only one interrupt. The choice of the interrupt may be based on the configuration of the module from which the interrupts are originated. In an embodiment of the present invention, the abstracted interrupt triggers an event. When the triggered event is completed, an interrupt may be fired off to the target module. An interrupt handler in the target module or an external interrupt handler may handle the interrupt that calls the target module.
