Disclosed are techniques for creating, coding, decoding, and using, rotation information related to one or more coded pictures in non-normative parts of a coded video bitstream.

Render-orientation information in video bitstream

Systems and methods for error resilient transmission and for random access in video communication systems are provided. The video communication systems are based on single-layer, scalable video, or simulcast video coding with temporal scalability, which may be used in video communication systems. A set of video frames or pictures in a video signal transmission is designated for reliable or guaranteed delivery to receivers using secure or high reliability links, or by retransmission techniques. The reliably-delivered video frames are used as reference pictures for resynchronization of receivers with the transmitted video signal after error incidence and for random access.

Systems and methods for error resilience and random access in video communication systems

A method may include receiving a first packet; determining, in a first processor, whether the first packet meets a criterion to be forwarded to a destination indicated in the first packet; receiving a second packet; determining whether the second packet is of a type for changing the criterion and sending the second packet to a second processor if the second packets is of the type for changing the criterion; receiving instructions, based on the second packet sent to the second processor, to change the criterion; and changing the criterion.

Systems and methods for implementing a protocol-aware network firewall

Systems and methods for multipoint video distribution are disclosed herein. In some embodiments, system for multipoint video distribution include at least one endpoint including a EECM and a DECM, and at least one server including a SECM, the server being coupled to the endpoint. In some embodiments, methods for configuring an encoder include receiving at least one property related to a capability of a decoder, determining a number of layers to be coded by the encoder, and configuring the encoder based on that at least one property.

Participant aware configuration for video encoder

An optimized gateway selection process of the present invention is based on a universal mobility manager (UMM), a component for inter-technology location management. The UMM is capable of holding location information for diverse cellular networks, as well as for Internet telephony systems. For cellular networks, UMM acts as a traditional HLR; for an Internet telephony network, it acts as the entities that are responsible for user/terminal registration (registrar in SIP, gatekeeper in H.323) and address resolution (proxy server in SIP, gatekeeper in H.323). An optimal gateway selection is possible based on location related information provided by the UMM which had not previously been available. Utilizing the newly available information enables a gateway to be selected which may, for example, enable the circuit switched portion of a call to now be minimized.

A Global Roaming Application Server is adapted to act as an intermediary between all Internet Protocol (IP)-based network(s) and non-IP-based network(s), such as a circuit-switched landline network, an ANSI-41 network, wireless LAN network, a Global System for Mobile Communications network or Universal Mobile Telecommunications System network. In a first or forward direction, the Application Server enables a user in a non-IP network to be located in accordance with user profiles at the request of another user who has chosen to send a message via an all-IP based network. After the user in the non-IP network is so located, the Application Server enables a signaling link to be created between the two users. The Application Server may also be used to enable a signaling link when a message is sent in a second, or reverse direction.

Methods and devices for providing seamless global roaming using an all-IP network

The call forwarding is provided within and between telephone networks by establishing a generalized procedure for call delivery and call forwarding. Network protocols are addressed using a common framework for processing call delivery and call forwarding among any combination of different types of networks. An 'integrated location management' component realizes the generalized procedure. The integrated location management component is a device capable of holding location information for diverse cellular networks, including Internet telephony systems. The inventive system and method executes generalized call delivery and call forwarding for calls among different types of telephone networks, including wireless networks and Internet networks. The calls may originate from any type of telephony network. Having been initially directed to any of these networks, calls can then be call forwarded to any of these networks.

System and method for generalized call forwarding between telephone terminals

The invention provides a telecommunication system that allows communication between a circuit-based wireless telephony network and a packet-based Internet telephony network without requiring access to the Public Switched Telephone Network. The system includes a circuit-based wireless telephony network providing wireless access to the system, a packet-based Internet telephony network providing Internet telephony access to the system, and a base station gateway controller for providing an interface between the wireless telephony network and the Internet telephony network. The invention further provides methods for facilitating communication between a first device, the first device being a packet-based Internet telephony network based device, and a second device, the second device being a circuit-based wireless telephony network based device, by facilitating connection of a call from the first device to the second device, without requiring access to the public switched telephone network.
