    • 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.

    • 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.

    • 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.
    • 数字数据分组传输过程和系统在诸如因特网电话的应用中提供更高效和更高质量的服务。 在该方法的一个方面,传输控制协议(“TCP”)用于通过标准电话线将数据从第一用户或客户端发送到本地因特网服务提供商(“ISP”)。 在ISP,数据包从TCP转换为用户数据报协议(“UDP”)。 然后,UDP数据包通常通过更高带宽的链路传输到为接收方服务的另一本地ISP。 UDP数据包被转换回TCP数据包并路由到接收器。 由于许多现有系统当前使用UDP数据包,如果接收者连接到不使用TCP / UDP转换器的ISP,则本方法大体上向后兼容。 双向TCP / UDP转换器对于诸如因特网电话的双向通信是优选的。

    • In a method for reducing latency in packet telephony caused by anti-jitter buffering, audio data elements are received and placed in a telephony input buffer used for anti-jitter buffering. Rather than wait until the buffer is full, the audio data elements are clocked, or played, out of the buffer at a rate slower than the normal play rate. In this way, latency due to the initial buffer fill period is reduced or eliminated. Audio data elements continue to be played out at a slower than normal rate until the buffer fill level reaches a threshold. At that time, the play rate for sending data elements out of the telephony input buffer is adjusted to the normal play rate. In an alternative embodiment of the present invention, the fill level of the telephony input buffer is controlled within a desired range by speeding up or slowing down the rate at which audio data elements are played out of the telephony input buffer. In yet another alternative embodiment, the amount of latency jitter in the packet network is measured and the size of the telephony input buffer is adjusted based upon the relative amount of jitter, such that the relative size of the buffer is reduced when the packet network is quiet, and the size of the buffer is increased when the network is relatively jittery.
    • 在用于减少由反抖动缓冲引起的分组电话中的等待时间的方法中,接收音频数据元素并将其放置在用于抗抖动缓冲的电话输入缓冲器中。 而不是等到缓冲器满了,音频数据元素以比正常播放速率慢的速率从缓冲器中计时或播放。 以这种方式,减少或消除由于初始缓冲器填充周期引起的延迟。 音频数据元素以比正常速率慢的速度继续播放,直到缓冲器填充电平达到阈值。 此时,将数据元素从电话输入缓冲器发送的播放速率调整到正常播放速率。 在本发明的替代实施例中,电话输入缓冲器的填充级别通过加速或减慢从电话输入缓冲器播放音频数据元素的速率来控制在期望的范围内。 在另一替代实施例中,测量分组网络中的等待时间抖动的量,并且基于抖动的相对量来调整电话输入缓冲器的大小,使得当分组网络为 当网络相对抖动时,缓冲区的大小会增加。
