摘要： A local server has a connection to a client and to a remote server over the Internet. The local server receives a request for an audio file from the client and, in response, transmits a requests for the audio file to the remote server. Upon receiving the audio file, the local server transcodes the audio file received from the remote server and then transmits the transcoded audio file to the client. Transcoding may include changing the audio file type, compressing the audio file, reducing the number of audio channels, or reducing the sampling rate of the data. The local server determines the extent and type of transcoding to be performed on the audio file as the audio file is downloaded from the remote server. The extent and type of transcoding are based on the file formats which the client is capable of handling, the size of the requested audio file, the memory capacity of the client, the bandwidth of the connection between the local server and the client, and the desired level of audio quality. Transcoding may be performed on-the-fly while the requested audio file is being downloaded to the local server from the remote server and while the modified audio file is being downloaded from the local server to the client.
摘要翻译：本地服务器通过Internet连接到客户端和远程服务器。本地服务器从客户端接收对音频文件的请求，作为响应，向远程服务器发送音频文件的请求。在接收到音频文件时，本地服务器对从远程服务器接收的音频文件进行转码，然后将转码的音频文件发送给客户机。转码可以包括改变音频文件类型，压缩音频文件，减少音频通道的数量，或降低数据的采样率。当从远程服务器下载音频文件时，本地服务器确定要在音频文件上执行的代码转换的范围和类型。代码转换的范围和类型基于客户端能够处理的文件格式，请求的音频文件的大小，客户端的内存容量，本地服务器和客户端之间的连接的带宽，以及所需音频质量水平。当所请求的音频文件从远程服务器下载到本地服务器并且修改的音频文件正在从本地服务器下载到客户端时，可以在运行时执行代码转换。

摘要： A proxy server transcodes audio data on behalf of a client computer prior to transmitting the audio data to the client computer. In response to a request from the client computer, the proxy server obtains the audio data from a remote server. If the proxy server determines that transcoding is appropriate, the proxy server transcodes the audio data and transmits the transcoded audio data to the client computer. Transcoding can include changing the type of the audio file, compressing the audio data, reducing the number of audio channels, or reducing the data sampling rate. The proxy server determines the extent and type of transcoding based on file formats that the client computer can process, the size of the requested audio file, the memory capacity of the client computer, the bandwidth of the connection between the proxy server and the client computer, and the desired level of audio quality.

摘要： Various embodiments enable a device to create a pool of at least one empty application. An empty application can be configured to contain resources that are common across one or more other applications and initialize the resources for the one or more other applications effective to reduce startup time of the other applications. In one or more embodiments, an empty application can further be populated with the one or more other applications effective to cause the one or more other applications to execute. Alternately or additionally, a device can be monitored for an idle state, and, upon determining the device is in the idle state, at least one empty application can be created.

摘要： A browser-based email system has a thin client connected to a host mail server. The thin client implements a browser. The host mail server provides pages to the thin client, which can be rendered by the browser to present an email service to a user. The thin client is equipped to receive audio and video data and supports a user interface to facilitate capture of the audio or video data for inclusion in an email message. After a data stream is captured and stored locally at the client, the browser submits a request to the host mail server that contains a token in lieu of the data stream. The host mail server returns a response specifying a new page that contains the email message. The response also includes the token and indicates a location in the new page at which the audio or video data is to be rendered. Upon receiving the response, the browser inserts the data stream into the new page at the location and renders the new page. After the user has reviewed the email message, the user can send the email message, causing the browser to submit another request to the host mail server that contains both the email message and the audio or video data. Upon receiving this second request, the host mail server converts the email message and the audio or video data to a MIME message and forwards the MIME message to the intended recipient.

摘要： Web browser software is implemented in a processing system housed in a set-top box connected to a television and communicating over a wide-area network with one or more servers. The browser allows a user to use a remote control device to navigate between hypertex, anchors in World-Wide Web pages displayed on the television. User inputs are entered from the remote control device using an infrared IR link in order to move a selection between hypertext anchors or various control buttons displayed on the television display. The browser is capable of downloading audio files from Web sites and generating sound through a speaker of the television set based on the audio files. Background music is generated during Web browsing based on audio files downloaded from one of the servers or audio files stored in memory in the set-top box. A background music audio file from a server can be downloaded while another background music audio file is played. An audio panel can be displayed when an audio file from a Web site is downloaded and played to form a user interface by which the user to play, stop, pause, rewind, or fast-forward the audio file.

摘要： Web browser software is implemented in a processing system housed in a set-top box connected to a television and communicating over a wide-area network with one or more servers. The browser allows a user to use a remote control device to navigate between hypertext anchors in World-Wide Web pages displayed on the television. User inputs are entered from the remote control device using an infrared IR link in order to move a selection between hypertext anchors or various control buttons displayed on the television display. The browser is capable of downloading audio files from Web sites and generating sound through a speaker of the television set based on the audio files. Background music is generated during Web browsing based on audio files downloaded from one of the servers or audio files stored in memory in the set-top box. A background music audio file from a server can be downloaded while another background music audio file is played. An audio panel can be displayed when an audio file from a Web site is downloaded and played to form a user interface by which the user to play, stop, pause, rewind, or fast-forward the audio file.
摘要翻译： Web浏览器软件被实现在容纳在与电视机连接的机顶盒中并且通过广域网与一个或多个服务器进行通信的处理系统中。浏览器允许用户使用远程控制设备在显示在电视上的万维网页面中的超文本锚之间进行导航。使用红外IR链接从遥控设备输入用户输入，以便在超文本锚或电视显示器上显示的各种控制按钮之间移动选择。浏览器能够从网站下载音频文件，并通过基于音频文件的电视机的扬声器产生声音。基于从服务器中的一个下载的音频文件或存储在机顶盒中的存储器中的音频文件，在Web浏览期间生成背景音乐。可以在播放另一个背景音乐音频文件的同时下载来自服务器的背景音乐音频文件。当来自网站的音频文件被下载并播放以形成用户播放，停止，暂停，倒退或快进音频文件的用户界面时，可以显示音频面板。
