摘要： In one embodiment, a method comprises receiving a primary stream of encoded frames and a separate stream of redundant frames. The method further comprises decoding and reconstructing in parallel the frames in the primary stream and the separate stream of redundant frames, on a real-time basis, in accordance with a specified common clock reference. The method further comprises, upon determining that a frame in the primary stream exhibits an error or impairment, determining a decoded redundant frame in the separate stream that corresponds to the impaired frame, and substituting at least a portion of the information in the decoded redundant frame for a corresponding decoded version of the impaired frame.

摘要： In one embodiment, characteristics of a connection traversing a packet switching device is determined, which includes, but not limited to, determining a network port number and/or address of an established connection based on a signature of the connection. In one embodiment, a packet switching device receives and forwards packets of particular communication between a device and a remote node in a network. The packet switching device maintains information of the particular communication and identification data for use in subsequent identification of said particular communication. In response to receiving a communications information request specifying a signature related to said particular communications, the packet switching device prepares and sends a response, which typically includes matching the signature to said maintained identification data resulting in identification of said information including a characterization of said particular communications, and sending a reply including the characterization of said particular communications.

摘要： Channel changes between services with differing bandwidth in a switched digital video system. A services map published by the headend and distributed to all of the edge devices, allows a bandwidth requirement to be correlated with each request from a device in the home. The bandwidth requirement is passed upstream along with the request for service and is subject to a system resource management validation.

摘要： Systems and methods of assembling an elementary stream from an encapsulated multimedia transport stream are disclosed. An exemplary method includes: receiving a command from a user mode video playback component; in response, processing layer-2 packets received through a network interface driver binding to assemble, into an MPEG elementary stream, multimedia transport packets encapsulated within; and supplying the stream to a decoder. The receiving and processing steps are performed in kernel mode. Also disclosed is an exemplary digital home communication terminal that includes a network interface, memory, and a processor. The processor executes code to: receive a command from a user mode video playback component; process layer-2 packets received through a network interface driver binding, in order to assemble into an MPEG elementary stream multimedia transport packets encapsulated within the received layer-2 packets; and supply the elementary stream to a decoder. The receive and process operations are performed in kernel mode.

摘要： Systems and methods are disclosed for providing reverse signals from a plurality of DHCTs to a downstream modulator that is located in the headend facility. The present invention includes a single wire return device (SWRD) that receives RF modulated signals, dynamically determines the address of the associated modulator, and converts the signals into Ethernet signals. The Ethernet signals are subsequently provided to the headend facility via fiber cable.

摘要： Set top boxes are provided with access to full EIT data streams without having to off-tune from one transport to another. If off-tuning is required, however, a locking mechanism substantially reduces or eliminates service interruption. Data in the additional EIT data streams in the non-home transports is reorganized to be sent by time rather than by service. EIT data is stored in the set top box in an architecture which significantly reduces the redundancy inherent in EIT data, allowing a full 7 days of EIT data to be stored in the set top box memory. The set top box of the present invention is backward compatible with conventional set top boxes.

摘要： A method includes detecting a substitution signal at a set top box device. The method includes inserting an advertisement into a media stream in response to detecting the substitution signal and determining an advertising fee associated with insertion of the advertisement into the media stream. A first advertising fee is determined when the advertisement is a local advertisement for a provider of a product or service and is to be inserted at a first location in the media stream that follows a national advertisement for the product or service. The first advertising fee is higher than a second advertising fee that is associated with insertion of the local advertisement for the provider of the product or service at a second location in the media stream.
