    摘要： A method for storing data across N storage devices S1 . . . SN, wherein at least one the storage devices has a storage capacity not equal to a storage capacity of others involves identifying a storage device SMAX having a largest capacity; encoding the data with an erasure encoder to produce F erasure codewords, where F= ∑ K = 1 N ⁢ F K and distributing the erasure codewords among storage devices S1 . . . SN in approximate proportion to the storage capacity CK of each of S1 . . . SN so that enough erasure codewords are stored in each of the N storage devices to assure that if any one of the storage devices become unavailable, all of the data stored in the systems can be restored using the fountain codewords stored in the remaining storage devices. The erasure codewords can be fountain codewords.

      摘要： A method of displaying items from an RSS feed on a television display involves registering the RSS feed with an RSS aggregator, the RSS feed aggregator being operatively coupled to the television display for display of RSS feed items; at the RSS aggregator, polling the RSS feed for RSS feed items; determining if the RSS feed contains an item that has been newly added since a preceding poll of the RSS feed; and if the RSS feed contains an item that has been newly added since a preceding poll of the RSS feed, downloading and displaying the newly added item on the television display replacing a previously displayed item from the RSS feed. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

      摘要： A PVR is selectively granted access to a hard disk drive. The HDD generates a random number, encrypts it with a key known to the PVR, and sends it to the PVR, which decrypts the number and increments it by one to render a new number. The new number is encrypted with the key and sent back to the HDD, which decrypts the new number, decrements it by one, and compares the result to the original number, granting the PVR access only when a match occurs.

      摘要翻译： 选择性地授予PVR访问硬盘驱动器的权限。 HDD生成一个随机数，用PVR已知的密钥对其进行加密，并将其发送到PVR，该PVR对该数字进行解密，并将其递增1以呈现新的数字。 新号码用密钥加密并发送回HDD，解密新号码，将其减1，并将结果与​​原始号码进行比较，仅在匹配发生时才授予PVR访问权限。
