Abstract: A method of encoding data for transmissions from a source to a destination over a communications channel is provided. The method operates on an ordered set of source symbols and may generate zero or more redundant symbols from the source symbols, wherein data is encoded in a first step according to a simple FEC code and in a second step, data is encoded according to a second FEC code, more complex than the first FEC code. The first FEC code and/or the second FEC code might comprise coding known in the art. These steps result in two groups of encoded data in such a way that a low-complexity receiver may make use of one of the groups of encoded data while higher complexity receivers may make use of both groups of encoded data.

Abstract: A method of encoding data operates on an ordered set of input symbols and includes generating redundant symbols from the input symbols, and includes generating output symbols from a combined set of symbols including the input symbols and the redundant symbols, wherein the number of possible output symbols is much larger than the number of the combined set of symbols, wherein at least one output symbol is generated from more than one symbol in the combined set of symbols and from less than all of the symbols in the combined set of symbols. The redundant symbols are generated from an ordered set of input symbols in a deterministic process such that a first set of static symbols calculated using a first input symbol has a low common membership with a second set of static symbols calculated using a second input symbol distinct from the first input symbol.

Abstract: Data is streamed from a transmitter to a receiver, wherein streaming is transferring data with an assumption that the receiver will begin using the data before it is all transmitted and received and the streamed data includes forward error correction (“FEC”) and the rates of data consumption can vary. The transmitter has an input rate and a transmit rate and the two rates can be different and can change. At the receiver, there is a reception rate (at which the receiver receives data) and a consumption rate (at which the receiver uses up data for its output). The transmitter transmits using a transmit rate higher than the consumption rate and the extra bandwidth is usable for FEC protection and buffering. In some embodiments, the excess rate varies over a transmission period.

Abstract: The present invention is concerned with situations in which call signalling follows an indirect path between an originating party and a destination party. Such an indirect path can occur when multi-homed communications networks are used. For example, where a service is provided to an enterprise which has a private address domain and that service is hosted by a service provider whose equipment is located in a public address domain connected to the enterprise domain by two or more address translators. Previously, in this type of situation, resulting media paths also follow the indirect path of the call signalling. This is wasteful of network resources. The present invention enables a direct media path to be set-up. This is achieved by enabling network address translators between two address domains to retain information in call set-up messages about the relevant address in the previous address domain and also by adding network identifier information to call set up messages.

Abstract translation: 本发明涉及呼叫信令遵循始发方和目的方之间的间接路径的情况。 当使用多宿主通信网络时，可能会发生这种间接路径。 例如，将服务提供给具有专用地址域的企业，并且该服务由其设备位于通过两个或多个地址转换器连接到企业域的公共地址域中的服务提供商托管。 以前，在这种情况下，所产生的媒体路径也遵循呼叫信令的间接路径。 这浪费了网络资源。 本发明使得能够建立直接媒体路径。 这是通过使两个地址域之间的网络地址转换器能够在关于前一地址域中的相关地址的呼叫建立消息中保留信息以及通过将呼叫建立消息中的网络标识符信息相加来实现的。

Abstract: According to one aspect of the present invention there is provided a method of preparing second protocol data for transmitting over a first protocol network comprising the steps of compressing the data to be transmitted in accordance with the first protocol, to produced first protocol compressed data and encrypting the first protocol compressed data in accordance with the first protocol to produce first protocol compressed and encrypted data. The invention consists of a means for the client to indicate to the first hop proxy that it wishes S/MIME encryption to be applied to part of an outgoing message. The first hop proxy then applies this encryption on behalf of the client. The encryption is therefore applied after the message has traversed the end terminal link. On the first proxy link, the message is sent without S/MIME encryption and can therefore benefit from compression (before the first hop IPSEC encryption is applied). A second aspect of the invention allows the support of end-to-end compression to be negotiated between end devices so that SIP compression can be applied to data before it is encrypted using S/MIME by the end system.

Abstract translation: 根据本发明的一个方面，提供了一种制备用于通过第一协议网络进行发送的第二协议数据的方法，包括以下步骤：根据第一协议压缩要发送的数据，以产生第一协议压缩数据和加密 第一协议压缩数据按照第一协议生成第一协议压缩和加密的数据。 本发明包括一种用于客户端向第一跳代理指示希望将S / MIME加密应用于传出消息的一部分的装置。 第一跳代理然后代表客户端应用此加密。 因此，在消息遍历末端终端链路之后应用加密。 在第一个代理链接上，消息不需要S / MIME加密就可以发送，因此可以受益于压缩（在应用第一跳IPSEC加密之前）。 本发明的第二方面允许端到端压缩的支持在终端设备之间协商，使得SIP压缩可以在终端系统使用S / MIME加密之前应用于数据。

Abstract: The present invention divides the recording head into multiple sections, each section accessing a subset of the total number of channels arranged such that one section reads and writes only a subset of the data channels. The sections may be either independently actuated for both coarse (data band) and fine (track-following) positioning, or linked by a common actuator for data band positioning with independent fine position actuators for fine track following.

Abstract: The invention is directed to a method and apparatus for decoding encoded data symbols. The invention is also directed to corresponding encoding methods. The decoder arrangement comprises an input for receiving encoded data and an identifier associated with a coding scheme used to create said encoded data. A processor in the decoding arrangement determines from the identifier, a mapping between said encoded data and the original data. A decoder uses the mapping to extract the original data from the encoded data. The operation of the decoder is independent of the coding scheme used in the encoding process.
