| 20110274156 | SYSTEM AND METHOD FOR TRANSMITTING MULTIMEDIA STREAM - Systems and methods for transmitting a multimedia stream are disclosed. A transmitter encodes audio data, video data, and control information received from a source and transmits over a network the different types of data to a receiver coupled to a display. The systems and methods utilize different network queues for the different types of traffic in order to account for differences in quality of service (QoS) parameters. The systems and methods adaptively adjust encoding and transmission parameters based on monitoring changing conditions of the network. | 11-10-2011 |
| 20110276710 | SYSTEM AND METHOD FOR LOW-LATENCY MULTIMEDIA STREAMING - Systems and methods for transmitting a multimedia stream over a communication link on a network are disclosed. The systems and methods adaptively adjust encoding parameters based on monitoring changing conditions of the network. A transmitter includes an adaptive-rate encoder that adaptively adjusts a video encoding bit rate in response to changing conditions of the communication link. The encoder maintains tight rate control by utilizing slice processing and sub-frame rate adaptation, as well as maintaining a headroom between the channel bit rate and the video encoding bit rate. The adaptive-rate encoder also embeds intra-frame constraints in predictive frames traffic in order to reduce latency. | 11-10-2011 |
| 20120281756 | Complexity change detection for video transmission system - A video transmission system includes an encoder and a decoder. As video data is encoded, the system uses temporal or spatial prediction to reduce the number of bits needed to encode frames. An increase in the complexity of the data results when motion vectors or patterns occurs. The complexity change is detected for intra-frame and inter-frame frames by monitoring statistics and motion estimation information for the macroblocks within the current frame. Once the complexity change is detected, the encoder or the system takes actions to prevent latency, bit rate fluctuation or quality degradation for the video transmission. | 11-08-2012 |
| 20120281757 | Scene change detection for video transmission system - A video transmission system includes an encoder and a decoder. As video data is encoded, the system uses temporal or spatial prediction to reduce the number of bits needed to encode frames. An increase in the complexity of the data results when a scene change occurs. The scene change is detected for intra-frame and inter-frame frames by monitoring statistics for the macroblocks within the current frame. Once the scene change is detected, the encoder or the system takes actions to prevent latency, bit rate fluctuation or quality degradation for the video transmission. | 11-08-2012 |
| 20120281766 | On-demand intra-refresh for end-to end coded video transmission systems - A video transmission system includes an encoder and a decoder. Data may be lost during video encoding and transmission, which leads to errors in reconstructing the video images by the decoder. A return channel couples the encoder and decoder so that errors detected by the decoder are made available to the encoder. Depending on the percentage of the image not received, refresh operations are performed. An on-demand intra-refresh operation is done when the percentage of the image needed to be refreshed is below a specified level. A random intra-refresh operation is done when the percentage of the image needed to be refreshed exceeds the level. | 11-08-2012 |
| 20120281767 | Low latency rate control system and method - An encoder within a video transmission system controls the bit allocation at a sub-frame level. A frame is divided into smaller blocks, known as rate control blocks. Rate control blocks are used as the basic unit for bit allocation. This bit allocation achieves the target bit rate desired by the system as well as meet latency constraints. The encoder uses the slice partitioning capabilities to generate the rate control blocks using one or more slices of the image frame. This feature allows the decoder to decode the rate control blocks independently and ensures that the encoded data size for each rate control block is allocated. The encoder also detects the overflow condition for the buffer and performing an operation to avoid the overflow condition based on whether the image frame is an inter-frame or a intra-frame. | 11-08-2012 |

| 20090310672 | Method and System for Rate Control in a Video Encoder - A method and system for a rate control block that adjusts the Quantization Parameter (QP) for a frame or macroblock based on the number of bits already used in encoding the frame or macroblock is disclosed. In an embodiment of the invention, the QP for a macroblock is adjusted dynamically against the QP for a frame as a function of the buffer occupancy. In another embodiment of the invention, a range of allowable QPs are defined based on the buffer occupancy. Embodiments of the invention are applicable to H.264 high-definition video conferencing. | 12-17-2009 |
