摘要： A portable media device (PMD) can produce an isochronous audio/video experience when the PMD provides a digital audio signal to the accessory while displaying analog video on an accessory-independent display. The accessory can communicate audio latency information to the PMD. The PMD can delay a video portion of a presentation, relative to providing the digital audio signal to the accessory, based on the audio latency information communicated by the accessory. As a result, the user may perceive an isochronous presentation of the audio and video portions of the presentation.

摘要： Improved approaches to update computer program code residing within a computing device are disclosed. By maintaining a former version of the computer program code, the computing device remains operable even if the update to the computer program code fails. Hence, the invention permits reliable updates to computer program code, which is particularly useful for firmware (e.g., boot-up code) of computing devices. For control and security, each version of computer program code can include authentication information. Before the computer program code is used, the computer program code can be required to be authenticated using the authentication information.
摘要翻译：公开了改进驻留在计算设备内的更新计算机程序代码的方法。通过维护计算机程序代码的先前版本，即使对计算机程序代码的更新失败，计算设备仍然可操作。因此，本发明允许对计算机程序代码的可靠更新，其对于计算设备的固件（例如引导代码）特别有用。为了控制和安全，每个版本的计算机程序代码都可以包含认证信息。在使用计算机程序代码之前，可能需要使用认证信息对计算机程序代码进行身份验证。

摘要： Improved techniques for presenting sound effects at a portable media device are disclosed. The sound effects can be output as audio sounds to an internal speaker, an external speaker, or both. In addition, the audio sounds for the sound effects can be output together with other audio sounds pertaining to media assets (e.g., audio tracks being played). In one embodiment, the sound effects can serve to provide auditory feedback to a user of the portable media device. A user interface can facilitate a user's selection of sound effect usages, types or characteristics.

摘要： Improved techniques to partially encrypt media files are disclosed. The encryption serves to cryptographically secure only a portion of the media data within a media file, while the remaining portion of the media data is not cryptographically secured. Although only partial encryption is used, the portion being encrypted serves to substantially disrupt usefulness of other parts of the media file which are not encrypted. In other words, the partial encryption renders the media file substantially unusable by unauthorized users. In one embodiment, the partial encryption is performed by a host device and thereafter the partially encrypted media file is delivered to a client device. The client device, if authorized, can subsequently decrypt the partially encrypted media file and utilize (e.g., play) the media file. However, since the media files are only partially encrypted, the decryption is likewise also only partial, which makes decryption faster and less resource intensive.
摘要翻译：公开了改进的部分加密媒体文件的技术。该加密用于在媒体文件中仅加密地保护媒体数据的一部分，而媒体数据的其余部分未被加密地保护。虽然仅使用部分加密，但是被加密的部分用于基本上中断未加密的媒体文件的其他部分的有用性。换句话说，部分加密使得媒体文件基本上不被用户授权。在一个实施例中，部分加密由主机设备执行，此后将部分加密的媒体文件传送到客户端设备。客户端设备（如果被授权）可随后解密部分加密的媒体文件并利用（例如，播放）媒体文件。然而，由于媒体文件仅被部分加密，所以解密同样也只是部分加密，这使得解密更快，资源密集度更低。
