摘要： A system, apparatus, and method are directed to converting from a use of a HTTPS connection to a tunnel connection while maintaining an underlying connection between a client and a server. An HTTPS connection is employed to establish a network connection between a client device and a network device. A gateway is selected to receive a request from the client device. In one embodiment, selecting may comprise using load-balancing, cookie-persistence, or the like. Subsequently, the HTTPS connection is transitioned to another application layer communication protocol connection. Transitioning may comprise converting from a use of a first protocol stack configured to process a HTTP connection to a second protocol stack configured to process a non-HTTP based application protocol connection, and establishing a tunnel between the client device and a server through the selected gateway.

摘要： The present invention provides methods and a system for transporting A/V data over a serial bus. A memory space is allocated for a set of buffers to store a plurality of CIPs. Each of the CIPs includes a header field and a data field with the header field having a SYT field for storing a presentation time. Initial CIP header values are generated including initial SYT field values for each of the CIP header fields in the set of buffers. A circular DMA script program is generated and configured to describe a set of full and empty CIPs for each of the buffers. The circular DMA script program is configured to transmit the CIPs from the buffers. The generated DMA script program is executed to sequentially transmit the CIPs from the buffers by traversing the buffers in a circular manner so that the transmitted CIPs are presented at the associated presentation time. The DMA script program generates an interrupt periodically to copy new CIP data into the CIP fields of buffers from which the CIPs have been transmitted such that the new CIP data including new SYT field values are set up for transmission in advance.
