Patent number: 8875203Abstract: A method of data management for efficiently storing and retrieving data in response to user access requests. The method includes receiving a request from at least one client for a title not resident in a storage server, where the title includes a play track having a plurality of chapters. The retrieval from a secondary storage device of play track portions proximate chapter delineation points is initiated, and bandwidth capacity and quality-of-service (QoS) parameters associated with the secondary storage device is determined. In the case of a client request to begin presentation of the title at one of the chapters, streaming of retrieved portions of the play track chapter to the client is initiated, masking latency associated with the secondary storage device is provided, and retrieval of at least unretrieved portions of the play track chapter and subsequent play track portions from the secondary storage device is initiated.Type: GrantFiled: February 18, 2010Date of Patent: October 28, 2014Assignee: Comcast IP Holdings I, LLCInventors: Clement G.

CONVENIENT VIDEO PROGRAM START OVER SYSTEM AND METHOD FOR A VIDEO ENTERTAINMENT DISTRIBUTION NETWORK
Publication number: 20140229999Abstract: A system and method are described herein for providing an convenient video program start over system and method for a video entertainment distribution network whereby a user may interactively revert back to the beginning of an ongoing video program that is currently broadcasted over the video distribution network. The novel system and method may be implemented on any video network having interactive television (ITV) capabilities, wherein user requests from a client are serviceable at an upstream head end, and video storage means exist for the purpose of storage of time based broadcast video programs. The system preferably utilizes a process that involves a minimally complicated sequence of commands that are easily understood and remembered by virtually any user, thereby enhancing the probability of consumer acceptance. The start over system and method may be embodied as a program of instructions, defining a controller, that are executed by a micro-processor located in the STB (client) or head end (server).Type: ApplicationFiled: April 21, 2014Publication date: August 14, 2014Applicant: COMCAST IP HOLDINGS I, LLCInventors: Sandi Hannum, James R.

Patent number: 8789104Abstract: A novel electronic program guide (EPG) based method and system for the distribution and display of programs enables the system service provider to determine which program a subscriber will initially see upon power-up of the subscriber's television receiver. The service provider maintains one or more Initial Program Display Tables that list information about programs to be displayed upon power-up of subscribers' receivers, from highest to least priority. The Initial Program Display Table or Tables are periodically transmitted to all subscribers and stored by the subscribers' set-top boxes. Upon power-up of a subscriber's receiver, the set-top box will attempt to cause the receiver to immediately display the highest ranked program from the Initial Program Display Table. The service provider controls which programs are displayed upon initial power-up and the ranking of programs in the case where there is difficulty displaying the highest ranked program.Type: GrantFiled: October 11, 2002Date of Patent: July 22, 2014Assignee: Comcast IP Holdings I, LLCInventors: Nathaniel J. Thurston, Devin F. Hosea
