The apparatus for constructing a multi-channel output signal using an input signal and parametric side information, the input signal including the first input channel and the second input channel derived from an original multi-channel signal, and the parametric side information describing interrelations between channels of the multi-channel original signal uses base channels for synthesizing first and second output channels on one side of an assumed listener position, which are different from each other. The base channels are different from each other because of a coherence measure. Coherence between the base channels (for example the left and the left surround reconstructed channel) is reduced by calculating a base channel for one of those channels by a combination of the input channels, the combination being determined by the coherence measure. Thus, a high subjective quality of the reconstruction can be obtained because of an approximated original front/back coherence.

An OpenFlow switch controls transmission and reception of a packet according to a flow entry. Each of the flow entries contains a matching condition showing a communication flow of the packet and an action showing processing on the packet. An OpenFlow controller generates a registration flow entry which is stored in a flow table of a specific OpenFlow switch arranged on a route of the communication flow. An encapsulated packet is generated by relating the registration flow entry and an ordinary packet. The specific OpenFlow switch extracts the registration flow entry from the encapsulated packet in response to the reception of the encapsulated packet to produce a new flow entry and executes the action shown in the new flow entry.

A cache server is provided in a network for storing Java objects for retrieval by one or multiple application servers. Application server(s) are configured to request an object from the cache server, rather than requesting the Java object directly from a database, so as to reduce processing load on the database and free up database resources. Responsive to a request for a Java object from an application server, e.g., in an HTTP request, the cache server determines if the object is stored in memory and if so, serializes the requested object and sends the serialized object to the requesting server, e.g., in an HTTP response. The requesting server then deserializes the Java object. If the object is not stored in memory, the cache server instantiates the object (typically by requesting the object from the database), serializes the instantiated object and sends it to the requesting server. Cache coherency methods are also provided.

This invention describes a method for adjusting the loudness and the spectral content of digital audio signals in a real-time using warped spectral filtering. A warped processing module modifies a spectral content of a digital audio signal with a set of gains for a plurality of non-linearly-scaled frequency bands determined by a warping factor λ of a warped delay line. Warped delay line signals, generated by the warped delay line, are processed by a warped filter block containing multiple warped finite impulse response filters, e.g., Mth band filters, using individual warped spectral filtering in said plurality of the non-linearly-scaled frequency bands, which is followed by a conventional processing by a dynamic range control/equalization block. The present invention describes another innovation, that is embedding the warped processing module in a two-channel quadrature mirror filter (QMF) bank for improving processing efficiency at high sample rates.

Upon reception of a transport stream of information data from an encoder, an RTP transmission process unit employed in an RTP process circuit is activated to packetize the transport stream in an RTP packet. A network device then outputs the resulting RTP packet to a network. At that time, sender information for the transmission is created and stored. On the other hand, an RTP reception process unit employed in the RTP process circuit depacketizes an RTP packet received from the network through the network device to obtain a transport stream and supplies the transport stream to a decoder. At that time, receiver information for the reception is created and stored. An RTCP process means employed in a control unit on the host side acquires the sender information and the receiver information through an internal bus and uses them to create an RTCP packet to be output to the network by way of the network device. As a result, the streaming quality can be assured independently of the state of the control unit on the host side.
