Because of their nature, handheld computing / electronic devices with access to the Internet can experience limited access to content available on the Internet. For example, web sites may be inaccessible or the devices' view of a web page may be restricted. Herein is described a system that reduces these limitations by acting as a proxy / intermediary server between the handheld device and the Internet. When such a device makes a request for information from the Internet, that request goes through the system. The system retrieves the content from the Internet, transforms, reformats, and translates the content into a more usable format, and then returns the transformed content to the device. The result is the device has access to more Internet sites and is also able to view Internet content that it otherwise would not be able to see.

Provided are a new hybrid audio decoder and a new hybrid audio encoder having block switching for speech signals and audio signals. Currently, very low bitrate audio coding methods for speech and audio signal are proposed. These audio coding methods cause very long delay.
