Patent number: 8375409Abstract: Meta-channels identify content entries and indicate an order with which to experience the content entries. The meta-channels may include a multi-source meta-channel that includes at least a first content entry that relates to first content broadcast by a first content provider at a specific time and a second content entry that relates to second content made available, over a network, by a second content provider in response to user requests. A selection of a meta-channel is received and the selection of the meta-channel is mapped to a content entry defined by the selected meta-channel. A media system is controlled to render content based on a content entry mapped to by the selected meta-channel.Type: GrantFiled: February 5, 2009Date of Patent: February 12, 2013Assignee: PurpleComm Inc.Inventors: Jack H.

Patent number: 8370874Abstract: Subscription and channel management technology, in which a system allows a user to subscribe to a subset of the available channels on a content delivery network and personalize at least one channel. The system identifies a user identity of the user and stores, in a user database, channel subscription information for the user identity based on the subset of channels to which the user subscribed and the user personalization. The system identifies a downloader device associated with the user identity and controls the downloader device based on the channel subscription information stored in the user database.Type: GrantFiled: June 7, 2010Date of Patent: February 5, 2013Assignee: PurpleComm Inc.Inventors: Jack H.

Publication number: 20100199311Abstract: Caching related technology, in which a time needed to begin rendering network-based video content without caching a decoded version of the content is determined and, the determined time to begin rendering the network-based video content is compared to a threshold time. When the determined time to begin rendering the network-based video content exceeds the threshold time, an initial portion of the network-based video content is pre-transcoded to a faster video codec format, and the pre-transcoded initial portion of the network-based video content is stored in electronic storage associated with a media system of a user.Type: ApplicationFiled: February 5, 2009Publication date: August 5, 2010Applicant: PURPLECOMM INC.Inventors: Jack H.

Publication number: 20100199318Abstract: Content download technology, in which a network-based video scheduled to be played at a particular time is identified, and multiple sources from which the network-based video is available for downloading are identified. An initial source from which to download the network-based video is selected from among the multiple sources, and a first process to download the network-based video from the initial source is initiated. Progress of the download of the network-based video is monitored. When an estimated amount of time remaining for the download of the network-based video from the initial source to complete does not enable viewing of the network-based video at the particular time without interruption, an alternative source from which to download at least a portion of the network-based video is selected from among the multiple sources, and a second process to download at least the portion the network-based video from the alternative source is initiated.Type: ApplicationFiled: February 5, 2009Publication date: August 5, 2010Applicant: PURPLECOMM INC.Inventors: Jack H.

Patent number: 7369648Abstract: PBX-integrated unified messaging capabilities are provided via a switched backbone (such as the Internet) without having to install or deploy on-premise unified messaging equipment. A Corporate Communication Platform (“CCP”) typically located within a corporate subscriber's premises is integrated with the corporate subscriber's private branch exchange (“PBX”) system and coupled to a switched backbone, such as the network commonly referred to as the Internet. The CCP comprises a local mailbox database that temporarily stores voice messages and/or facsimile transmissions for and transmits messages to individual subscribers associated with the corporate subscriber. A CCP forms part of a wide-area unified messaging system, and connects to this wide-area unified messaging system via the switched backbone. The wide-area unified messaging system also comprises one or more System Communication Platforms (“SCP”).Type: GrantFiled: July 6, 2000Date of Patent: May 6, 2008Assignee: Purplecomm, Inc.Inventor: Jack H.

Patent number: 7177908Abstract: The present invention manages a messaging network having messaging platforms interconnecting through a switched backbone such as the Internet. The master platform monitors each messaging platform on the messaging network and administers the addition, deletion, and updating of messaging platforms by modifying a master global routing table in the event the master platform encounters changes to the status of the messaging platforms. In the event that the master global routing table is updated, the global routing table held at each messaging platform is also updated, ensuring version consistency between said master global routing table and each of the global routing tables. This enables the master platform and each messaging platform to determine the operational status of another messaging platform. The present invention may also provide a cost tracking scheme when delivering messages between messaging platforms that are owned by different entities.Type: GrantFiled: January 18, 2002Date of Patent: February 13, 2007Assignee: Calumet Keweenaw LLCInventors: Jack H. Chang, Raymond L. Tong

Patent number: 7010574Abstract: A messaging network has a plurality of messaging platforms interconnected through a switched backbone, such as the Internet. A master platform can receive and store status messages destined for a messaging platform that does not have an active connection to the messaging network or is in a non-operational state. In one embodiment, a messaging platform requests information from an information source outside the messaging network. The master platform sends the information request message to the information source and receives a response message therefrom. The response message is sent to the requesting messaging platform. In another embodiment, messages may be transformed into a format specified by the subscriber and delivered thereto.Type: GrantFiled: January 18, 2002Date of Patent: March 7, 2006Assignee: Calumet Keweenaw LLCInventors: Jack H. Chang, Raymond L. Tong

Publication number: 20030018720Abstract: The invention is an apparatus and method for receiving a message having a first format and for converting the message from the first format to a second format that is compatible for reception by a messaging interface having a destination address corresponding to an intended recipient. In the preferred embodiment, a computer system is used to receive and send messages between messaging interfaces and networks which may be dissimilar from each other. A variety of network interfaces is used to communicate with the networks and which may optionally have a first interface and a second interface for interfacing to a first and second network, respectively. The messages may optionally be presented through a web page. A forwarding program or equivalent may be used to forward subscriber messages to or from remote locations served by a remote computer system, enabling a messaging user to use the remote computer system as a local access point.Type: ApplicationFiled: April 9, 1999Publication date: January 23, 2003Inventors: JACK H. CHANG, RAYMOND L. TONG
