US Patent:

20020061062, May 23, 2002

Filed:

Mar 6, 2001

Appl. No.:

09/800146

Inventors:

Royal O'Brien - Jacksonville FL, US

International Classification:

H04N011/04
H04N011/02
H04N007/12
H04B001/66

US Classification:

375/240010

Abstract:

A system and methodology for eliminating noise distortions and mosaic effects from decoded multimedia data. Such system and methodology preferably uses an encoding/decoding application such as that developed by the Moving Picture Experts Group (MPEG). The present invention ideally processes selected sections of sub-macroblocks of pixels based on a constant established threshold derived from human perception of gradients in color hues. By applying unique algorithms for sub-macroblock edge correction, noise correction, and temporal correction, the present invention enables a method for eliminating decompressed video image distortions.

Appl. No.:

10/039440

Inventors:

Royal O'Brien - Jacksonville FL, US

International Classification:

H04N007/12

US Classification:

375/240120, 375/240270

Abstract:

A system and method for real-time transcoding of video data for transmission into a desired encoded format and bit-rate includes decoding, intra-transcoding, encoding and post-encoding processing. Decoding accommodates various input video data formats. Intra-transcoding processing includes deinterlacing, cropping, error correction and synchronization. Encoding accounts for post-codec processing of video data to remove compression errors before display. Post-encoding operations include encryption, packet identification and archiving.

Appl. No.:

10/171360

Inventors:

Royal O'Brien - Jacksonville FL, US

International Classification:

H04N007/12

US Classification:

375/240160, 375/240270

Abstract:

A system and methodology detects blocks conducive to error in decoded digital video data. Pixel values for target blocks are compared with determined pixel values for blocks conducive to error. By process of elimination the methodology efficiently determines whether the block is (or is substantially similar to) a block that is conducive to error. Target blocks that are (or are substantially similar to) blocks that are conducive to error are identified for error correction.

Appl. No.:

10/171317

Inventors:

Royal O'Brien - Jacksonville FL, US

International Classification:

H04N007/12

US Classification:

375/240270

Abstract:

A system and methodology assesses whether an error correction should be applied to detected blocks based on determined correction application criteria, and, if warranted according to the assessment, applies block-specific error corrections to detected blocks. Global error corrections, such as edge corrections, are also enabled.

Filed:

Feb 12, 2003

Appl. No.:

10/365190

Inventors:

Royal O'Brien - Jacksonville FL, US

International Classification:

H04L012/28

US Classification:

370/392000

Abstract:

A system and method for fault tolerant multimedia communication provides a first connectionless channel for communicating packets from a server to a client. Packets are either header packets or media packets. Header packets include only a header payload providing information pertaining to succeeding media packets. One or more media packets corresponding to a single frame of video succeeds each header packet. The client detects missing packets and determines whether or not the missing packet is a header packet. If a header packet is missing, the corresponding succeeding media packets are not processed. Instead, the system waits until the next header packet is received to resume processing of media packets succeeding that next received header packet. If a media packet is missing, the client may continue processing media packets received, although the resulting video may be somewhat distorted, especially if the received media packets depend upon the missing media packet for proper processing. Client-side buffering may be employed to detect missing packets before they are due for processing and request via a second channel, which may be connection-based or connectionless, that a server resend the missing packets if a determined amount of time remains until the missing packets are due for processing.

Appl. No.:

10/631406

Inventors:

Royal O'Brien - Jacksonville FL, US

International Classification:

H04L009/00

US Classification:

380/281000, 380/284000

Abstract:

A digital content security system and method encrypts a key required for playback of digital content, fragments the encrypted key and embeds the fragments in portions of a payload; encrypts determined portions of frames of the digital content, and uses the decrypted key to decrypt the encrypted portions for playback in real-time; and requires an active authenticated session to access the encrypted key, decrypt it, access the encrypted portions and decrypt them.

US Classification:

725/088000, 725/089000, 725/134000, 725/105000, 725/092000, 725/039000

Abstract:

A system for streaming data includes a channel for communicating requests between a client and server and another channel for transmitting streaming video. The client creates a media file for archiving received video data. A global list maintained by the client identifies all available data in the media file. A monitoring thread tracks the global list to identify unavailable data needed for playback, identify approaching data discontinuities, merge global list entries for contiguous chunks of available data and identify remaining unavailable data. The client requests unavailable data from the server until the media file is full. A client-side player with a graphical user interface facilitates pause, stop, play, fast forward, jump (scroll), and rewind operations. The system may play video data as streamed and store the streamed video data for playback in a download and store mode.

Abstract:

A system and method for gaming on demand in real time via a computer network indexes game segments and prioritizes segments of a game to be downloaded, such that segments of a game needed immediately to play at a current level are downloaded, and then portions which correspond to levels accessible from the current level are downloaded. Downloading of the portions corresponding to directly related levels, and then portions corresponding to other levels, may occur while the game is being played at a current level.
