Patent number: 8863192Abstract: Information included within metadata broadcast within an overhead flow of a mobile broadcast network enables receiver devices to determine when metadata updates will occur. The mobile broadcast network can include within metadata messages information related to a time for the next metadata update. Using this information, receiver devices can determine when the next metadata update will occur and de-energize the receiver until that time. Enabling mobile devices to remain de-energized until the next metadata update improves their power efficiency. Synchronizing mobile devices to access the overhead flow for updated metadata reduces the content delivery latency that the system must accommodate, thereby improving system flexibility and bandwidth efficiency. Specify the time of a next metadata update enables the broadcast system to change the rate and timing at which metadata updates are performed.Type: GrantFiled: January 7, 2010Date of Patent: October 14, 2014Assignee: QUALCOMM IncorporatedInventors: Qiang Gao, Qi Xue, Carlos Marcelo Pazos

Patent number: 8776135Abstract: A digital television (DTV) signal for use in a DTV receiver includes an extended text table (ETT) which includes a header and a message body. The header includes a table identification extension field which serves to establish uniqueness of the ETT, and the message includes an extended text message (ETM). If the ETT is an event ETT, the table ID extension field includes an event identification which specifies an identification number of an event associated with the ETT. On the other hand, if the ETT is a channel ETT, the table identification extension field includes a source identification which specifies a programming source of a virtual channel associated with the ETT. A section-filtering unit included in the DTV receiver is able to use table identification extension fields of a plurality of ETTs for section-filtering a pertinent event or channel ETT from the ETTs.Type: GrantFiled: December 19, 2013Date of Patent: July 8, 2014Assignee: LG Electronics Inc.Inventors: Jin Pil Kim, Kyung Mee Lee

Publication number: 20140189750Abstract: Systems and methods for distributing digital satellite broadcast programs over multicast Internet Protocol (IP) networks are provided. A satellite receiver gateway receives a signal from a digital satellite broadcast and generates service information multicast packets that are transmitted over a multicast IP network. A device receives the service information multicast packets and generates a channel list or electronic program guide for a user. When a user selects a service from the channel list or electronic program guide the device sends a service request for the service towards the satellite receiver gateway. Either the satellite receiver gateway or a switch within the multicast IP network can then transmit the service in multicast IP packets to the requesting device.Type: ApplicationFiled: March 5, 2014Publication date: July 3, 2014Applicant: International Datacasting CorporationInventors: Gary CARTER, Bastian STASSEN

Patent number: RE44991Abstract: In a program information broadcasting system, it is aimed to minimize time for retrieval of program by viewers in operating an electronic program guide or time for waiting when applying for subscription. As a program information broadcasting system, program elements constituting a broadcasting program are divided into a plurality of items and are turned to data at a center, and a master data 21 of a program information to recognize the program is prepared. From the data constituting the master data, minimal necessary items for preparation of a program table are extracted, and a program basic information 22 is prepared. Said master data and said program basic information are transmitted simultaneously with the broadcasting, and said program basic information is received, reproduced and displayed before receiving of the master data at a receiving terminal unit 31 is completed.Type: GrantFiled: August 24, 2011Date of Patent: July 1, 2014Assignee: Panasonic CorporationInventors: Ryota Tsukidate, Kenichi Fujita, Shigeki Kaneko, Yoshiyasu Takeuchi
