Abstract: A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.

Abstract: A method of negotiating a proper communication protocol between a reader device (10) and a data carrier (20) is disclosed. In a first step, when the data carrier (20) is inserted into the reader device (10) at a first point in time (t1), the data carrier (20) provides information to the reader device (10), which communication protocols are supported by the data carrier (20), by means of a binary value (BV). In a next step, the reader device (10) chooses/sets one of the possible communication protocols according to its own capability. This choice is provided to the data carrier (20) by applying a clock signal (CLK) of a certain frequency (f), which is associated with the chosen/set communication protocol, to an input contact (C3) of the data carrier (20) at a second point in time (t2). Finally, the data carrier (20) sets the chosen communication protocol received from the reader device (10), thereby finalizing the negotiation sequence.

Abstract: In one embodiment, program code is added to a social network's web pages or site such that the content a first user accesses is locally stored at the first user's system. When another user, who is a friend of the first user, as defined by the social networking site, browses to that same content, the program code fetches it from the first user, instead of directly from the social networking site. The content is thus directly exchanged between the users without a transaction at the website. The present invention leverages the storage and bandwidth resources of social networking users to help serve content.

Abstract: The invention provides a mechanism for a transaction coordinator to indicate to a transaction participant that it supports a heuristic outcome, where a course of action has occurred which means that the transaction participant is unable to honor a transactional prior commitment to the transaction coordinator. The mechanism is such that a transaction participant that is incapable of communicating a heuristic outcome may ignore any such indication. A transaction participant may be incapable because it does not understand the concept of a heuristic outcome at all or because it does not have the ability to inform the transaction coordinator that a heuristic outcome has occurred.

Abstract: The present invention is directed towards systems and methods for managing SSL session persistence and reuse in a multi-core system. A first core may indicate that an SSL session established by the first core is non-resumable. Responsive to the indication, the core may set an indicator at a location in memory accessible by each core of the multi-core system, the indicator indicating that the SSL session is non-resumable. A second core of the multi-core system may receive a request to reuse the SSL session. The request may include a session identifier of the SSL session. In addition, the session identifier may identify the first core as an establisher of the SSL session. The second core can identify from encoding of the session identifier whether the second core is not the establisher of the SSL session. Responsive to the identification, the second core may determine whether to resume the SSL session.
