摘要:
An analyzer analyzes portions of a logical data stream including data content received from a source. Based on analyzing the data content (e.g., data content formatted according to Moving Picture Experts Group (MPEG)) received from the source, the analyzer generates metadata associated with multiple analyzed portions of the logical data stream. The metadata supports manipulation of how the logical data stream is presented when at least a portion of the data content of the logical data stream is later presented to a receiver for play back in a mode different than the original content (e.g., play back includes fast forwarding, rewinding, and/or pausing.

Disclosed is a communication technology in which the effect of packet loss can be easily reduced to the extent that it can be ignored, even on networks where packet loss can easily occur. Specifically, a communication device is disclosed that includes a packet loss determination unit that determines whether a packet that transmits image information has been lost, and an interpolated packet transmission unit that transmits an interpolated packet when a packet that transmits image information has been lost.

Systems and methods are disclosed for supporting a pull data flow scheme in an A/V decoder. One method relates to processing data using an A/V decoder comprising receiving the data from a data stream and recovering a system time reference from the received data. The received data is processed using a clock asynchronous to the system time reference and pulled into an output device using a system adapted to support a pull data flow. The processed data is output using a time reference locked to the system time reference.

A method includes receiving a command to provide media content configured to be sent to a display device for display at a particular scan rate. The media content includes audio data and video data. The method includes identifying high priority segments of the media content based on the audio data. The high priority segments are to be displayed by the display device at a presentation rate such that the high priority segments displayed at the presentation rate correspond to the media content displayed at the particular scan rate. The method also includes sending the high priority segments to the display device to provide video content and audio content of the requested media content for display.

A tagging system provides a mechanism for inserting tags into an audio or video television broadcast stream prior to or at the time of transmission. The tags contain command and control information that the receiver translates and acts upon. The receiver receives the broadcast stream and detects and processes the tags within the broadcast stream which is stored on a storage device that resides on the receiver. Program material from the broadcast stream is played back to the viewer from the storage device. The receiver performs the appropriate actions in response to the tags.

A broadcasting method and a broadcast signal receiving apparatus is provided wherein auxiliary information, such as video and audio data for supplementing broadcast information presented through a broadcasting network in an interlocked manner can be watched and listened to by the viewer. Broadcast information received from a broadcasting network is temporarily stored in a storage means of a broadcast signal receiving apparatus and a recording medium for storing auxiliary information used as a supplement to the broadcast information is mounted on the broadcast signal receiving apparatus. The broadcast information and the auxiliary information are then played back in an interlocked manner with a predetermined timing. As a result, a function to present information which cannot be accommodated in a broadcast frame and a parental function can be implemented.

Embodiments of an apparatus for implementing a display port interface are disclosed. The apparatus may include a source processor and a sink processor coupled through an interface. The sink processor may be operable to send a synchronization signal to the source processor through the interface. The source processor may be operable, dependent upon the synchronization signal, to send data to the sink processor.

A method and apparatus for variable accuracy inter-picture timing specification for digital video encoding is disclosed. Specifically, the present invention discloses a system that allows the relative timing of nearby video pictures to be encoded in a very efficient manner. In one embodiment, the display time difference between a current video picture and a nearby video picture is determined. The display time difference is then encoded into a digital representation of the video picture. In a preferred embodiment, the nearby video picture is the most recently transmitted stored picture. For coding efficiency, the display time difference may be encoded using a variable length coding system or arithmetic coding. In an alternate embodiment, the display time difference is encoded as a power of two to reduce the number of bits transmitted.
