  • Patent number: 10225320
    Abstract: An arrangement is provided in which a Universal Plug and Play (UPnP) device exposes a service for mapping a UPnP discovered content item to a server message block (SMB) location. The service is arranged to expose an SMB share path to a user at a remote client using a UPnP protocol. The user is then enabled with access to the share via SMB to gain file access, write changes or exercise file level control of the discovered content item. Authentication is optionally utilized to verify that the user is authorized to receive the SMB share location from the service or to verify that the user is authorized to access the SMB share.

  • Patent number: 7882356
    Abstract: A secure handshake service is implemented among a plurality of UPnP (Universal Plug and Play) portable media devices and endpoints in an open network hosting one or more UPnP services. A first portable media device receives a first request for a hosted service from a second portable media device via the network. The first portable media device authenticates authorizes the second portable media device as a function of the certificate of the request. The second portable media device is allowed to access the requested service hosted on the first portable media device if the second portable media device has been authenticated and authorized by the first portable media device.

  • Patent number: 7543073
    Abstract: A system and process for performing an exponentially weighted moving average on streaming data to establish a moving average bit rate of data units is presented. In general, the system or process computes, on a unit-by-unit basis, the product of the moving average bit rate computed for a data unit immediately prior to a unit under consideration and a first fractional weighting factor, added to the product of the instantaneous bit rate of the data unit under consideration and a second fractional weighting factor, wherein at least one fractional weighting factor is not a constant but instead based on the time between data units.

  • Patent number: 7536469
    Abstract: A system and process for controlling the coding bit rate of streaming media data is presented where a server streams data that exhibits one of a number of coding bit rates supported by the server. Initially, the server chooses the coding bit rate. However, after this startup period, the client provides coding bit rate requests. The server transmits the streaming media data at the most appropriate supported coding bit rate closest to the rate requested. The coding bit rates requested are those estimated to provide a high quality playback of the streaming data while still keeping a decoder buffer of the client filled to a desired level. A leaky bucket model is incorporated so that the changes in buffer duration due to natural variation in the instantaneous coding bit rate are not mistaken for changes in buffer duration due to network congestion.

  • Patent number: 7451229
    Abstract: A system and method for embedding a streaming media format header within a session description message. The streaming media format header is encapsulated within a session description message as a header attribute. The streaming media format header describes complex relationships between available media streams. The session description message also includes a list of content description attributes storing metadata about the media streams. A media description field in the session description message stores a stream attribute identifying a media stream associated with the media description field.

  • Publication number: 20070150596
    Abstract: Publishing content using a peer-to-peer content distribution system is described. A publisher is required to request authorization to publish from an authorization body. Resources such as tracker and seed nodes are allocated in a peer-to-peer content distribution system and pre-processing of content to be published is carried out. For example, a content description is generated for each item of content as well as a set of checksums or other items for validating blocks of content. Publication can be terminated in a variety of different ways. For example, by using expiry methods, by active revocation of publishers, authorization bodies, or individual items of content.

  • Publication number: 20070086481
    Abstract: An RTP payload format for VC-1 is described. The RTP payload format accommodates an RTP payload that can include one or more Access Units (AUs). An Access Unit can provide a complete frame of VC-1 information. Alternatively, a frame of VC-1 information can be fragmented among multiple Access Units. Each Access Unit includes an Access Unit header and an Access Unit payload. The RTP payload format incorporates various provisions for improving the efficiency and robustness in the processing of the VC-1 information, enabled, in part, by control information conveyed by the respective Access Unit headers of the Access Units.

  • Publication number: 20070038873
    Abstract: Systems and/or methods (“tools”) are described that enable a digital rights management policy to be associated with digital media having an arbitrary content type or transfer control protocol. In some embodiments, the tools encrypt data segments of a media file and add a descriptor to each of those segments. These descriptors can enable a receiver of the encrypted media file to decrypt the file and consume it according to the correct digital rights management policy.

  • Publication number: 20060282566
    Abstract: A client device receives streaming content from a host device. The streaming content is placed in one or more buffers prior to processing. Monitoring as to the capacity and fullness of the buffers is performed at the client device and information is sent to the host device. The host device adjusts the rate or flow of the streaming content based on the information provided by the client device.

  • Publication number: 20060184790
    Abstract: Protecting elementary stream media content is described. In one aspect, Media Access Units (MAUs) of elementary stream content are identified. Each MAU includes one or more data segments representing a single video or audio frame. Encryption boundaries are selected for each MAU. The encryption boundaries are based on one or more data segments associated with the respective MAU. Portions of each MAU are encrypted based on corresponding encryption boundaries. Each MAU is mapped to a MAU Payload Format. The MAU Payload Format allows a media consumer to process each elementary stream associated with the elementary stream content independent of any different elementary stream. The MAU Payload Format also allows a media consumer to process each MAU in an elementary stream independent of any other MAU.

  • Publication number: 20060168295
    Abstract: Systems and methods for midstream determination of varying available bandwidth for streaming content between two network entities are described. During content streaming, a client requests a server to surge the content transmission rate. One or more bandwidth measurements are taken during the surge to determine if the increased transmission rate can be adequately managed. If the increased transmission rate can be adequately managed, the client may request the server to transmit remaining content at a transmission rate that is not greater than the increased, or surged, transmission rate. In a multi-bitrate file scenario, the surge rate may be higher than the rate of the fastest useable stream. In such a case, the fastest useable stream is selected. If the increased transmission rate is not suitable for future transmission, then the rate may remain at the original transmission rate.
