    摘要： An apparatus is provided. The apparatus has an interface for receiving media information, wherein the media information indicates a segment data rate for each of a plurality of media data segments and further indicates a quality value for each of the plurality of media data segments. Moreover, the apparatus has a processor for selecting one or more selected segments from the plurality of the media data segments depending on the segment data rates of the plurality of media data segments, depending on the quality values of the plurality of media data segments and depending on an available data rate of a communication resource. The interface is configured to transmit a request requesting the one or more selected segments. Moreover, the interface is configured to receive the one or more selected segments being transmitted on the communication resource.

    摘要： Media streaming is more efficient in terms of transmission bitrate consumption, transmission latency and/or fair trade of transmission capacity among several by pushing media content rather than the client pulling media content from the server. Pushing media content to the client at a varying bitrate enables to shift, at least partially, the control over the streaming from the client towards the server. The server may continue to push segments of the media content to the client even without receiving explicit queries or directives for these segments thereby reducing upstream bandwidth consumption. As far as the bitrate adaption is concerned, the server may act as a slave remotely controlled by the client in that media content is pushed at a bitrate depending on the client's most recently sent information such as reception situation information explicitly indicating the bitrate to be used.

    摘要翻译： 通过推送媒体内容而不是客户端从服务器拉取媒体内容，媒体流在传输比特率消耗，传输延迟和/或传输容量的公平交易方面更有效。 以不同的比特率将媒体内容推送到客户端使得能够至少部分地移动对从客户端到服务器的流的控制。 即使没有接收到这些段的显式查询或指令，服务器也可以继续将媒体内容的段推送到客户端，从而减少上行带宽消耗。 就比特率适应而言，服务器可以作为由客户机远程控制的从属，因为根据客户端最近发送的信息（例如明确指示要使用的比特率的接收状况信息），媒体内容按比特率被推送 。

    摘要： Techniques for video encoding are described herein. A method for video encoding with smart chunking includes receiving, by a distributed video encoding system, a video input and a target bitrate, the video input having segments of a segment duration, determining an internal chunk length that is a multiple of the segment duration, encoding chunks having the internal chunk length, wherein the average bitrate across the chunk is equal to the target bitrate, and segmenting the encoded chunks into encoded segments of the segment duration. The distributed video encoding system may include various video encoders, or encoder instances, able to encode multiple chunks in parallel. The encoded segments may be output to a client, all of the encoded segments being of equal or similar quality.

    摘要： An apparatus for transmitting user data to a server system including one or more servers includes a content encoder for encoding a plurality of portions of the user data to obtain a first data stream, wherein the content encoder is configured to encode each of the plurality of portions with a bandwidth-dependent quality which depends on a bandwidth that is available for transmitting the first data stream from the apparatus to the server system, and includes a transmitter for transmitting the first data stream from the apparatus to the server system. The content encoder is configured to encode two or more of the plurality of portions of the user data to obtain a second data stream, wherein the content encoder is configured to encode each of the two or more of the plurality of portions with a predefined quality.
