| 20090232129 | METHOD AND APPARATUS FOR VIDEO SERVICES - A method for providing a multimedia service to a multimedia terminal includes establishing an audio link between the multimedia terminal and a server over an audio channel, and detecting one or more media capabilities of the multimedia terminal. The method also includes providing an application logic for the multimedia service, establishing a visual link between the multimedia terminal and the server over a video channel, providing an audio stream for the multimedia service over the audio link, and providing a visual stream for the multimedia service over the video link. The method further includes combining the video link and the audio link, and adjusting a transmission time of one or more packets in the visual stream to synchronize the visual stream with the audio stream. | 09-17-2009 |
| 20100061448 | METHOD AND APPARATUS FOR TRANSMITTING VIDEO - A method of transmitting a coded media frame comprises determining a plurality of media frame sizes including a media frame size, transmitting an element comprising the plurality of media frame sizes, and thereafter receiving an input media frame. The method also includes processing the input media frame according to the media frame size to provide a coded media frame, and transmitting the coded media frame. | 03-11-2010 |
| 20100268836 | Method and apparatus for delivery of adapted media - A method of transmitting media to a client by an infrastructure device in a packet-switched network includes receiving a media stream at the infrastructure device. The method also includes determining an adaptation strategy according to at least one of one or more pieces of network information associated with the packet-switched network, one or more pieces of client information associated with the client, or one or more policies. The method further includes adapting the media stream according to the adaptation strategy to produce an output media stream. | 10-21-2010 |

| 20080310438 | Methods and system for fast session establishment between equipment using H.324 and related telecommunications protocols - Methods of establishing multimedia telecommunication (a multimedia “call”) between equipment (“terminals”). More particularly, the invention provides methods for reducing the time required to establish calls between terminals implementing ITU-T Recommendation H.324 and derived or related standards or recommendations such as 3G-324M. More specifically, it relates to methods and apparatuses for (i) concatenating H.245 messages to pass between the terminals at the start of the call to establish the capabilities of both terminals and agree on the type and format of media and data to be exchanged (ii) using non-standard H.245 messages or standard H.245 messages with non-standard fields to accelerate establishment and (iii) informing each terminal of the capabilities of the other and proposing the type and format of media and data to be exchanged by means of fields inserted in the call signaling protocol used for bearer establishment prior to the H.324 stage of the call. | 12-18-2008 |
| 20090196344 | METHOD AND APPARATUS FOR TRANSCODING BETWEEN HYBRID VIDEO CODEC BITSTREAMS - A method and apparatus for performing transcoding between bitstreams coded by hybrid video codecs which uses fewer resources than decoding/decompressing the original bitstream and recoding/recompressing it to the second format. According to a specific embodiment, the present method can exploits the similarity of the standard video compression algorithms to, where possible, convert encoded parameters in the incoming bitstreams directly into encoded parameters which constitute compliant data for the outgoing bitstream. | 08-06-2009 |
| 20100277562 | Fast session setup extensions to H.324 - A multimedia device configured to support video in a session of a call includes one or more media providing devices and one or more computer codes directed to performing an initialization process for the one or more media providing devices. The initialization process may be performed at an initialization time prior to or substantially equal to a first time prior to or substantially equal to a reception time associated with receiving an indication of call acceptance from a called device, or second time prior to or substantially equal to an acceptance time associated with call acceptance by the multimedia device. The multimedia device also includes one or more computer codes directed to transmitting one or more preferences for the session according to a session setup procedure, one or more media processors coupled to the one or more media providing devices, and one or more computer codes directed to transmitting media on one or more media channels associated with the session. | 11-04-2010 |
