Appl. No.:

12/881006

Inventors:

Diem V. Nguyen - Anaheim CA, US
Titus Winters - New York NY, US
Jonathan Kochel - Chaska MN, US

Assignee:

The DIRECTV Group, Inc. - El Segundo CA

International Classification:

H04N 7/173

US Classification:

725116, 725 32, 725135, 725136, 725137

Abstract:

A system and method for controlling closed-captioning at a client device includes a client device and a server device that communicates content to the client device. The server device determines a content type corresponding to the content communicated from the server device to the client device, generates a closed-captioning disable signal and communicates the content type disable signal to the client device. The client device disables the closed-captioning in response to the closed-captioning disable signal.

International Classification:

G06F 15/16

US Classification:

709203

Abstract:

A system and method for displaying graphics in a content distribution system includes a client device and a server device that communicates an allocate buffer command signal to the client device. The client device reserves an off-screen buffer having buffer identifier associated therewith and communicates a buffer response signal comprising the buffer identifier to the server device. The server device communicates a write command signal comprising graphics data and the buffer identifier to the client device. The client device stores the graphics data in an off-screen buffer in response to write command signal, transfers the graphics data from the off-screen buffer to an on-screen buffer and displays graphics corresponding to the graphics data on a display associated with the client device. A bit blit command may be used to transfer the graphics data from the off-screen buffer to the on-screen buffer.

Appl. No.:

11/828520

Inventors:

Xavier D. Riley - Los Angeles CA, US
Diem V. Nguyen - Anaheim CA, US

Assignee:

The DIRECTV Group, Inc. - El Segundo CA

International Classification:

H04N 7/20

US Classification:

725 63, 725 64, 725 73

Abstract:

A communication system includes a content repository storing a plurality of content files associated with the content distribution system. A transport processing system communicating with the content distribution system, a terrestrial communication network , and a content delivery network communicating with the content distribution system and the terrestrial network. The content distribution system assigns a satellite category or a broadband category to each of the plurality of content files in response to the satellite category. The content distribution system communicates the content to the transport processing system. The transport processing system communicates the content through a satellite from the transport processing system to a user device. The content distribution system, in response to the broadband category, communicates the content to the content delivery network. The content delivery network communicates the content through a terrestrial communication network to the user device.

International Classification:

H04B 7/185

US Classification:

370316

Abstract:

A communication system includes a content management system determining a programming schedule and a video transport processing system receiving a content file in forming a transport stream from the content file having a plurality of packets, each having a header with a first packet identifier in the header and a data portion. The communication system further includes a content repository storing the content in a satellite transport processing system changing the first packet identifier to a second packet identifier in response to the programming schedule and communicating the transport stream to a user device.

Assignee:

The DIRECTV Group, Inc. - El Segundo CA

International Classification:

H04N 7/173

US Classification:

725 93

Abstract:

A communication system includes a content management system determining broadband content availability, a video transport processing system generating a plurality of packets for a content stream or in at least some of the packets comprising all packets, and a transport processing system dividing the broadband content availability into broadband content availability packets. The transport processing system replaces the null packets with the broadband content availability packets in the content stream and communicates the plurality of broadband availability packets to a user device through the satellite with the content stream.

International Classification:

H04N 17/00

US Classification:

348181, 348E17001

Abstract:

A system and method for testing a set top box includes a test manager module in communication with the set top box having a test script including a bitstream. A bitstream player in communication with the test manager module receives the bitstream and communicates the bitstream to the set top box. The test manager module receives a screen image from the set top box that is generated in response to the bitstream. An optical character recognition module performs optical character recognition to obtain a test text string from the screen image. The test manager module compares the test text string with an expected text string. A report module generates a report in response to comparing.
