Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for performing enhanced file distribution in multicast communication or broadcast communication allowing more efficient download and processing of a broadcast file. SOLUTION: In a communication system providing broadcast services, files for broadcast are accessible by users. The content of the broadcast files and the content of file attributes required to process the broadcast files are separately sent. As arranged thus, receiving the file attributes ahead of the content files allows more efficient download and processing of the broadcast files. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To detect errors and recover data while minimizing the impact on device resources such as power consumption.SOLUTION: It is attempted to receive a subset of an initial amount of code packets, which should be at least k(1+ε) packets, from a plurality of code packets transmitted during a contact window, where k represents the number of data packets encoded to produce the transmitted code packets and ε is initialized using an initial minimum value not smaller than zero. A method comprises detecting a trigger event that indicates a decode error associated with the subset of the initial amount of code packets, increasing ε from the initial minimum value based on the trigger event, and receiving one or more additional code packets during the contact window.

Abstract translation: 要解决的问题：在最小化对设备资源（如功耗）的影响的同时检测错误和恢复数据。 解决方案：尝试从在联系窗口期间发送的多个代码分组中接收初始量的码分组的子集，其应至少为k（1 +ε）分组，其中k表示数字 的编码以产生发送的码分组的数据分组，并且使用不小于零的初始最小值来初始化。 一种方法包括检测指示与初始数量分组的子集相关联的解码错误的触发事件，基于触发事件从初始最小值增加ε，以及在联系窗口期间接收一个或多个附加码分组。 版权所有（C）2012，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide techniques for video-encoding and decoding channel switch frames (CSF) to enable acquisition and re/synchronization of a video stream while preserving compression efficiency.SOLUTION: Systems and methods to process multimedia data enabling channel switching are presented. The systems generate a CSF with one or more network abstraction layer (NAL) units as a random access point (RAP) frame. Back-to-back frames are transmitted which include the CSF and a non-RAP frame, each having the same frame ID number.

Abstract: PROBLEM TO BE SOLVED: To provide a more effective scheme for higher-quality broadcasting and a scheme for much more economical utilization of a communication resource, in a method and an apparatus for performing enhanced file distribution in a multicast and a broadcast. SOLUTION: A user can access a file for the broadcast in a communication system for providing a broadcast service. Contents of the file for the broadcast, which are required to process the broadcast file, are differently transmitted from those of file attributes. Through such arrangement, more effective download and processing can be expected in the broadcast file by receiving the file attribute earlier than the contents file. COPYRIGHT: (C)2011,JPO&INPIT

解决方案：用户可以在用于提供广播服务的通信系统中访问用于广播的文件。 用于处理广播文件所需的用于广播的文件的内容与文件属性的内容不同。 通过这样的安排，通过接收比内容文件更早的文件属性，可以在广播文件中预期更有效的下载和处理。 版权所有（C）2011，JPO＆INPIT
