Patents by Inventor Stephen E. Loomis

Stephen E. Loomis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10084835
    Abstract: A broadcaster may be configured to use a media protocol to provide a distribution point with a stream. The broadcaster uses a controller configured to implement the media protocol that includes a message class indicating an applicability of a message to a distribution point. The media protocol includes an authentication message structured and arranged to authenticate an establishment of a stream for distribution on the distribution point, a stream configuration message structured and arranged to configure the stream being distributed on the distribution point, a connection message structured and arranged to distribute the stream, and a stream session termination message structured and arranged to terminate a streaming session that has been established.
    Type: Grant

  • Publication number: 20130173921
    Abstract: An initialization vector (IV) is employed to decrypt a block of a stream that has been encrypted with Cypher Block Chaining (CBC) encryption, without requiring decryption of previous blocks within the stream. For example, a listener who accesses a distribution point to retrieve encrypted content authenticates himself to an application server that regulates access to encrypted content on the distribution point, and responsively receives a key. The listener then requests access to a reference point within the encrypted content stream somewhere after its beginning (e.g., using preview clips). The distribution point relates the reference point to a corresponding block of the encrypted stream, and identifies an IV previously used for encryption of that block. The distribution point provides the associated encrypted block of content and the IV to the listener to enable mid-stream rendering of the encrypted content, without requiring the listener to decrypt previous blocks within the encrypted stream.
