    摘要: A method and apparatus for dynamic quality adjustment based on changing streaming constraints is provided. According to one aspect of the present invention, a video stream is sent to a client according to a set of streaming constraints. At least a subset of the video information in the video stream is sent from a first source. Next, a signal is received indicating a relaxation of streaming constraints corresponding to the video stream. In one embodiment, the signal is a freeze frame signal. In another embodiment, the signal is a slow motion signal. In response to the signal, a set of improved quality video information from a second source is accessed and sent to the client. According to one embodiment, the set of improved quality video information comprises a still image. According to another embodiment, the set of improved quality video information comprises a set of preprocessed video information ready to be streamed. As a result of the techniques described herein, an improved quality visual image is available for presentation on the client and, consequently, when a viewer requests a presentation rate that reduces the streaming constraints on a video streaming service, the improved quality video information may be sent using the freed-up portion of the bandwidth previously allocated to the client.

    摘要: A method and system for storing a continuous feed of video is provided. According to one aspect of the invention, the continuous feed is encoded in a digital video format to produce a digital data stream. A series of content files is created by repeatedly performing the steps of (1) storing the digital data stream in a current file, and (2) establishing a new file as the current file when the current file satisfies a predetermined condition. If the series of content files satisfy a particular deletion criteria, then a particular content file that satisfies a particular deletion criteria is deleted. A determination is made as to whether any reader is currently playing information from the particular content file. If it is determined that a reader is playing information from the particular content file then the step of deleting the particular content file is delayed. In certain aspects, tag information that indicates information about frames contained in the digital data stream is generated. The tag information includes timestamps that indicate timing of frames relative to a beginning of the digital data stream. An initial time value that indicates an absolute time that corresponds to the beginning of the digital data stream. When a request from a client for playback beginning at a specified absolute time is received, the initial time value is subtracted from the specified absolute time to determine a relative time. The tag information is used to identify a location in the digital data stream that corresponds to the relative time. The digital data stream is then transmitted to the client beginning at the location in the digital data stream that corresponds to the relative time.

    摘要: A method and apparatus for dynamic quality adjustment of digital media based on changing streaming constraints is provided. A digital media server sends a digital media stream according to a set of streaming constraints to a requesting client. Audio and visual information may be sent to a requesting client together in a single stream, or separately in multiple streams. A client sends a request over a control network to the digital media server indicating information of a particular type is no longer desired. In response to receiving the signal, the video server ceases transmission of that particular type of information to the signaling client, thus relaxing streaming constraints. As a result of the techniques described herein, an improved quality digital presentation is available for the client and, consequently, when a viewer signals that a particular type of information is not desired, that particular type of information is not transmitted to the client, which thereby reduces the streaming constraints on a video streaming service, and improved quality digital media information may be sent to any client using the freed-up portion of the bandwidth previously allocated to the signaling client.

    摘要: A streaming media server is provided for dynamically resolving a request for digital content based upon the identity of the requester. The digital content may be specifically tailored to the demographics of the viewer, and need not be physically stored in sequence. Information about a viewer of digital video is stored within a user profile. The collection of all user profiles is maintained by a profile manager. When a viewer requests a digital data stream from the media server, a content resolver, coupled to the media server, determines how to service the request based upon the appropriate user profile. In certain embodiments, the content resolver may be configured to send targeted advertisements towards the requester of the digital data stream. In other embodiments, the content resolver may be configured to send personalized information pertaining to the requesting user. In other embodiments, the content resolver may personalize the requested content according to the user profile.
