Abstract:
Un procedimiento de procesamiento de datos que comprende datos de vídeo codificados, comprendiendo el procedimiento: transmitir (180) datos a través de una red a una primera velocidad de transferencia de bits, R0; identificar (182) una reducción de una velocidad de enlace de red de la red desde una primera velocidad de enlace de red a una segunda velocidad de enlace de red, R1; implementar (190) una reducción de la velocidad de transferencia de bits de transmisión; caracterizada por en respuesta a la identificación de la reducción de la velocidad de enlace de red, determinar (184) una velocidad de transferencia de bits de recuperación, Ru, en la que transmitir los datos a través de la red determinando Ru >= (1-fu) x R1, donde el factor de no sobrepaso, fu >=(R0-R1)/R0, en el que la velocidad de transferencia de bits de recuperación es menor que la segunda velocidad de enlace de red; determinar (186) una duración de almacenamiento en memoria intermedia basándose en una diferencia entre un momento de la identificación de la reducción de la velocidad de enlace de red y un tiempo real estimado de la reducción de la velocidad de enlace de red; determinar (188) una duración de velocidad de recuperación durante la cual transmitir los datos a la velocidad de transferencia de bits de recuperación basándose en la duración del almacenamiento en memoria intermedia, una magnitud de la reducción de la velocidad de enlace de red, R0-R1, y el factor de no sobrepaso, fu; y en el que implementar (190) una reducción de la velocidad de transferencia de bits de transmisión comprende además implementar una reducción de la velocidad de transferencia de bits de transmisión a la velocidad de transferencia de bits de recuperación durante el tiempo de velocidad de recuperación determinad realizando control de velocidad para reducir la velocidad de transferencia de bits de los datos a la velocidad de transferencia de bits de recuperación durante el tiempo de velocidad de recuperación determinada.
Abstract:
Data objects are delivered over a packet switched network and receivers receive encoded symbols such as repair symbols broadcast or multicast with sufficient information to form requests for additional symbols as needed based on what source symbols or sub symbols are needed or missing. The requests can be made in a unicast or request fashion. Requesting and broadcasting might be done by different entities. A broadcast server can generate and store repair symbols while a source server can store content in source form. A request can be a unicast HTTP byte range request such as a URL starting position and length. Requests might be aligned with starting positions of files. A receiver can calculate starting and ending byte positions of symbols or sub symbols in a file and get indications that conventional HTTP servers are usable for file repair. Repair servers can request broadcast of repair data when byte range requests from multiple receivers overlap.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in which at least one bit rate for allocating network resources from a broadcast-multicast service center (BM-SC) is received. The network resources are then allocated based on the at least one bit rate. Moreover, all evolved Node Bs (eNBs) in a broadcast/multicast area are informed of the network resource allocation. Additionally, the network resources are allocated for a session based on a first bit rate, wherein the first bit rate is greater than a guaranteed bit rate (GBR), and the network resource allocation is adjusted to a second bit rate based on the occurrence of an event, wherein the second bit rate is equal to GBR.

Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus includes an user equipment which is configured to measure Minimization of Drive Tests (MDT) metrics, to measure Quality of Experience (QoE) metrics, to generate correlation information of at least one of the MDT metrics and at least one of the QoE metrics, and to report the correlation information.
