摘要： A personal information device (PID) is coupled to an IP Telephony phone in order to provide end-to-end connectivity to another PID through a network. The architecture disclosed includes a pair of internet-enabled phones that are able to establish a call session using a Session Initiation Protocol (SIP) and a Session Description Protocol (SDP). Each phone is also provided with an interface configured to communicate with a PID. Each PID is registered to a corresponding internet-enabled phone using each PID user's SIP URL. The user of a first PID connected to a first phone requests a call to a SIP URL corresponding to the user of the second PID that is connected to a second phone. The SIP URL for the user of the second PID is resolved to the network address of the second phone and connection is established between the first and second phones. The connection includes a media stream for transferring data between each of the PIDs. A data object transmitted by the first PID through its interface with the first phone is transmitted to the second phone through the media stream of the connection between the first and second phones. The data object received by the second phone is transmitted to the second PID through the interface between the second phone and the second PID.
摘要翻译：个人信息设备（PID）被耦合到IP电话电话，以便通过网络提供到另一个PID的端到端连接。所公开的架构包括能够使用会话发起协议（SIP）和会话描述协议（SDP）建立呼叫会话的一对因特网的电话。每个电话还具有配置成与PID进行通信的接口。每个PID都使用每个PID用户的SIP URL注册到相应的启用互联网的手机。连接到第一电话的第一PID的用户请求与连接到第二电话的第二PID的用户对应的SIP URL的呼叫。用于第二PID的用户的SIP URL被解析为第二电话的网络地址，并且在第一和第二电话之间建立连接。该连接包括用于在每个PID之间传送数据的媒体流。由第一PID通过其与第一电话的接口发送的数据对象通过第一和第二电话之间的连接的媒体流被发送到第二电话。由第二电话接收的数据对象通过第二电话和第二PID之间的接口发送到第二PID。

摘要： A system and method for providing advertising and advertising services using a telephone system. A data network telephony system includes a commercial message server that communicates with a telephony connection server to communicate commercial messages to display devices on data network telephones. A caller uses the data network telephone to make a telephone call to a callee. The commercial message server receives information about the connection and retrieves commercial messages, or advertisements to communicate to either the caller, the callee or both.

摘要： A computationally simple yet powerful forward error correction code scheme for transmission of real-time media signals, such as digitized voice, video or audio, in a packet switched network, such as the Internet. According to one aspect, an encoder at the sending end derives p redundancy blocks from each group of a k payload blocks and concatenates the redundancy blocks, respectively, with payload blocks in the next group of k payload blocks. At the receiving end, a decoder may recover up to p missing packets in a group of k packets, provided with the p redundancy blocks carried by the next group of k packets. The invention may, for instance, append to each of a series of payload packets a single forward error correction code that is defined by taking the XOR sum of a preceding specified number of payload packets. The invention thereby enables correction from the loss of multiple packets in a row, without significantly increasing the data rate or otherwise delaying transmission.
摘要翻译：一种用于在分组交换网络（诸如因特网）中传输诸如数字化语音，视频或音频的实时媒体信号的计算上简单而强大的前向纠错码方案。根据一个方面，发送端的编码器分别从k个有效载荷块的每个组中导出p个冗余块，并将冗余块分别与下一组k个有效载荷块中的有效负载块相连。在接收端，解码器可以恢复一组k个分组中的p个丢失的分组，该分组具有由下一组k个分组携带的p个冗余块。本发明可以例如附加到一系列有效载荷分组中的每一个，其通过获取先前指定数量的有效载荷分组的异或并定义的单个前向纠错码。因此，本发明能够从一行中的多个分组的丢失中进行校正，而不会显着增加数据速率或以其他方式延迟传输。
