摘要： Disclosed is a networked multimedia information system which may be utilized to record, store and distribute multimedia presentations together with any supplemental materials that may be referenced during the presentation. The recorded presentation, together with the associated supplemental materials, may be simultaneously presented on a display containing two separate viewing windows. The effects of network congestion are minimized by prefetching audio and video data for storage in audio and video buffers. An adaptive control algorithm compensates for network congestion by dynamically varying the rate at which video frames are retrieved over the network, in response to network traffic conditions. The audio playback speed is reduced if the audio data does not arrive fast enough over the network to maintain the desired size of the audio buffer after the amount of video data transmitted across the network has been reduced to a minimum value.
摘要翻译：公开了一种联网多媒体信息系统，其可以用于在呈现期间可以参考的任何补充材料与多媒体呈现一起记录，存储和分发。记录的演示文稿以及相关的补充材料可以同时呈现在包含两个单独的观看窗口的显示器上。通过预取音频和视频数据来存储音频和视频缓冲区，可以最大限度地减少网络拥塞的影响。响应于网络流量条件，自适应控制算法通过动态地改变通过网络检索视频帧的速率来补偿网络拥塞。如果在通过网络传输的视频数据量已经减少到最小值之后，如果音频数据在网络上没有足够快地到达，以保持音频缓冲器的期望大小，则音频播放速度降低。

摘要： In a method for reducing latency in packet telephony caused by buffering at the conversion stage between analog audio signals and digital audio data, analog audio is sampled at a rate far greater than necessary for telephony. The increased sampling rate allows the audio data to pass much more rapidly through the data conversion buffer. After passing through the buffer, the data is downsampled to a rate normally used for telephony. To handle audio data for speaker output, the data is upsampled to a rate far in excess of the rate necessary for processing telephony-grade voice signals. The increased sampling rate allows the audio data to pass much more rapidly through the data conversion buffer. After passing through the buffer, the data is converted into an analog audio signal for sending to the speaker. In this way, latency due to the buffering that accompanies the process of converting audio signals to digital data, or vice versa, is minimized.

摘要： A digital data packet transmission process and system provides; more efficient and higher quality of service in applications such as Internet telephony. In one aspect of this approach, transmission control protocol (“TCP”) is used to send data from a first user or client over standard telephone lines to a local Internet service provider (“ISP”). At the ISP, the data packets are converted from TCP to user datagram protocol (“UDP”). The UDP packets are then transmitted, typically over a higher bandwidth link to another local ISP serving the recipient. The UDP packets are translated back to TCP packets and routed to the receiver. Because many existing systems currently employ UDP packets, the present approach is largely backwards compatible should a recipient be hooked up to an ISP that does not employ a TCP/UDP converter. A bidirectional TCP/UDP converter is preferable for two way communication such as Internet telephony.

摘要： A server platform in the PSTN performs the service of calling the subscriber if the subscriber's customary commuting route is congested. The service makes an initial call when the fastest commute route is congested. It also makes additional calls each time it finds a better alternate route. The server can accommodate any subscriber commuting pattern. If a street on the subscriber's customary route is found to be congested, then the server sequentially tests additional streets having geographic coordinates nearby, dynamically searching for an alternate route that has an acceptable level of congestion. The server has a voice response unit (VRU) in the platform, to announce to the subscriber that the subscriber's customary commuting route is congested. Following an initial call to the subscriber, the server continues to search for better alternate routes having the least congestion and it calls the subscriber again if it finds a better alternate route.

摘要： A billing method and server for gathering and processing billing information for Internet telephony connections. Originating and terminating clients and Internet Service Providers ("ISPs") are identified by the server from information contained in digital packets. The digital packets also identify the beginning and ending time of the connection, as well as enhancements chosen for the particular connection, and choices of information to be displayed during the connection. The billing server transmits selected information to each client during the connection, such information including packet routing, packet density, elapsed time of connection, and available and selected enhancements. The server constructs a billing detail for each connection and constructs a billing record for each ISP and client over a specific time period. The server periodically forwards each billing record to its associated ISP.

摘要： The present invention provides a system and method for providing handwritten messages with electronic communication devices. For example the electronic communication device may be a mobile communication device and may include a touch screen, screen buffer memory, processor, and transceiver. In preferred embodiments, the mobile communication device may be a personal digital assistant (PDA), a two-way pager, or a mobile telephone. The mobile communication device user may create a handwritten message on the touch screen using, for example, a stylus. In one exemplary embodiment, the handwritten message displayed on the touch screen may be stored to the buffer memory as an image, directed by the processor to the transceiver, and transmitted via a wireless connection to, for example, a wireless base station and the Internet. The Internet may route the handwritten message image to a desired Internet address. The handwritten message may be displayed in real time on the recipient's display, e.g., an instant message (IM) session, or stored in their email mailbox for later retrieval and display. The recipient may type in a text message in response to the hand written message, and this message will be transmitted to mobile communication device and displayed on the mobile communication device. In another embodiment, the receiving party may also have handwritten messaging capabilities (included with, for example, a PC, PDA or a mobile phone) and may respond with a handwritten message.

摘要： A method and system are disclosed for updating announcements on a packet network site such as a website. An exemplary method includes receiving an announcement through an audio interface and storing the announcement on a website server. In accordance with the exemplary method, merchants without Internet access can now update announcements on their websites quickly and economically by using an audio interface such as a conventional telephone. The updated announcements may be either audio or data. If the announcement received in the exemplary method is an audio announcement, it is converted from a first audio format into a second audio format prior to the step of storing the announcement. Whether the announcements are audio or data, the merchants' customers can then retrieve them by accessing the merchants' websites via the Internet.

摘要： A method and apparatus that provide enhanced directory assistance information. An operator receives a request for directory information about a listed party over a telephone connection. It is then determined if enhanced directory information for the listed party is available in an enhanced information database. The enhanced directory information associated with the listed party is retrieved, from the enhanced information database, as a script that incorporates the enhanced directory information. The enhanced directory information can then be provided using the script. The enhanced directory information can be stored, for example, on a Web server that is updated by the listed party and the information can be transferred using a Phone Markup Language script.
