Problems solved by technology

Such a wait can be intolerable
Second, in an environment with limited network bandwidth, the entire file must be transferred even if the user only wants to watch the first few seconds of the video
Thus, in wireless access networks where devices are regularly added and removed from specific cells, the client has limited awareness of utilizing the full bandwidth, which may affect its ability to predict appropriate encoding and screen resolutions in a timely and accurate manner

Embodiment Construction

[0046] figure 2 A device 112 is illustrated that is aware of communications on the RAN network and shows intercept points where the device can plug into the 3G / UMTS network. Device 112 is located between RNC 105 and SGSN 104 . This figure is an exemplary deployment in a 3G / UMTS network; although exemplary deployments in other RAN networks (such as in a CDMA network) are not shown, the methods described here are equally applicable to such networks . Additionally, device 112 may be located between other components in the 3G / UMTS network, such as between NodeB 106 and RNC 105 , or between SGSN 104 and GGSN 103 .

[0047] The device 112 can be aware of communications between the UE 107 and the core network. In some embodiments, device 112 is capable of decoding a control plane and a user plane. Such a device is described in co-pending patent application Ser. No. 12 / 536537, filed August 6, 2009, which is hereby incorporated by reference in its entirety. This enables determina...

Abstract

A network device, capable of understanding communications between an end user and the core network on a RAN network is disclosed. In some embodiments, the device is able to decode the control plane and the user plane. As such, it is able to determine when the end user has requested multimedia content. Once this is known, the device can optimize the delivery of that content in several ways. In one embodiment, the device requests the content from the content server (located in the core network) and transmits this content in a just-in-time manner to the end user. In another embodiment, the device automatically changes the encoding and resolution of the content, based on overall monitored network traffic. In another embodiment, the device automatically selects or modifies the format and resolution options based on overall bandwidth limitations, independent of the end user.

Description

[technical field] [0001] The invention relates to the technical fields of communication and computer, in particular to an adaptive block and content-aware synchronization device and method for multimedia transmission. [Background technique] [0002] One of the most popular network-intensive computer applications is video or multimedia playback on the Internet. A few years ago, it was believed that the Internet, with its aging protocols and lack of guaranteed delivery, could not support video playback at a quality that satisfied users. However, apps such as YouTube and Netflix have demonstrated that high-quality video playback is possible. [0003] Various mechanisms have been created to improve the user experience. For example, in some embodiments, a user with a media player requests and receives a full multimedia file before starting to play the file. This ensures that, once the file starts playing, it continues playing without interruption. While acceptable in the case...
