摘要： When the reception level of a main tuner (3) is equal to or lower than a first threshold or the reception level of a sub tuner (4) is equal to or lower than a second threshold while the sub tuner (4) performs data service reception, a sub tuner processing control unit (90), a broadcast program search control unit (91), and a data service control unit (93) cause the sub tuner (4) to suspend the running data service reception and start a broadcast program search. Then, while the reception level of the main tuner (3) is equal to or lower than the first threshold or the reception level of the sub tuner (4) is equal to or lower than the second threshold, the sub tuner processing control unit (90) and the broadcast program search control unit (91) cause the sub tuner (4) to repeatedly and continuously perform a broadcast program search.

摘要： Provided are a method and device for providing a video of an Internet Protocol TV or Interactive Personal TV (IPTV) service. The method includes: detecting whether an IPTV service system is accessible for a terminal or not; and when the IPTV system is detected to be inaccessible for the terminal, providing a video for the terminal through a Content Delivery Network (CDN) subsystem. By the technical solution, the technical problems that the user cannot enjoy services such as the video service in case of upgrading, server failure or network failure in the related technology are solved, and live video service can still be provided for the user even though the service of the IPTV service system is inaccessible due to upgrading, server failure or network failure.

摘要： The approach shown provides for an efficient implementation of time response, level response and frequency response alignment between two audio sources such as DAB and FM that may be time offset from each other by as much as 2 seconds, and produces an aurally undetectable transition between the sources. Computational load is significantly reduced over the approaches known in the prior art.

摘要： Intelligent switching of audio sources includes determining, via a computer processor communicatively coupled to an audio system in a vehicle, alternative sources of content that are communicatively available to the vehicle. The audio system renders an instance of a content item that has been received from a content provider, as a source of content, over a network. Upon determining an interruption in a signal from the content provider with respect to the instance of the content item, the intelligent switching of audio sources also includes presenting an alternative content item, through the audio system, from one of the alternative sources of content.

摘要： Disclosed is a technique for effectively transmitting a plurality of contents under the situation securing minimum QoS. According to the technique, among a plurality of contents to be transmitted to a data reception device, two or more contents are set as main contents, and the remaining contents are set as stand-by contents. One of the two or more main contents is set as a broadcasting content to be broadcasted actually, and the remaining main content is set as a switching content. The data transmission device transmits the two main contents to the data reception device via a high-quality line (main content line) and transmits the remaining stand-by contents via a line of a quality lower than the main content line (proxy data transmission line). Contents are switched by interchanging between a broadcasting content and a switching content and interchanging between a switching content and a stand-by content.

摘要： A method and apparatus for performing dynamic time alignment of program content extracted from analog and digital radio signals of a simulcast is disclosed. A delay estimation unit of a radio receiver is configured to dynamically determine an amount of received delay between analog-transmitted and digital portions of a radio program. An internal delay to compensate for the received delay may be applied to a data stream corresponding to the portion that is leading. The radio receiver may initially provide audio output from the analog-transmitted portion. In the case of leading analog-transmitted audio, the audio from the analog-transmitted portion may be incrementally delayed to align with the digitally transmitted audio. Once data streams corresponding to the analog-transmitted and digitally transmitted portions are sufficiently aligned in time, a blend operation may be performed. The blend operation may transition the output from being sourced by the analog-transmitted portion to the digitally-transmitted portion.
摘要翻译：公开了一种从联播模拟和数字无线电信号中提取的节目内容进行动态时间对准的方法和装置。无线电接收机的延迟估计单元被配置为动态地确定无线电节目的模拟发送和数字部分之间的接收延迟量。补偿接收到的延迟的内部延迟可以应用于对应于正在引导的部分的数据流。无线电接收机可以初始地提供来自模拟发送部分的音频输出。在引导模拟发送音频的情况下，来自模拟发送部分的音频可以被递增地延迟以与数字传输的音频一致。一旦对应于模拟发送和数字发送部分的数据流在时间上充分对准，则可以执行混合操作。混合操作可以将来自模拟发送部分的输出转变为数字发送部分。

摘要： Methods and systems for communicating information in a network are disclosed herein and may include receiving, at a mobile terminal, a high definition television (HDTV) signal via a DVB-H downlink communication path. A standard definition television (SDTV) signal may be simultaneously received at the mobile terminal via a cellular downlink communication path. The SDTV signal and the HDTV signal may comprise the same media content. The HDTV signal received via the DVB-H downlink communication path and the SDTV signal received via the cellular downlink communication path may be selected in the mobile terminal for processing. The selection may be based on a preference indicated via the mobile terminal. The selection may also be based on at least one downlink channel condition indicator corresponding to the HDTV signal or the SDTV signal.

摘要： Providing content to a device. Content stored on a device can be examined or searched based on the programming of channels that are available to the device over various networks. The content can be searched using other rules related to user preferences or content characteristics. Based on the results of the examination of the content, playlists are generated. Each playlist includes content from the device that matches or partially matches the content associated with one of the channels. Using the playlists, a user can load content from their device that has a theme consistent with a particular channel. When signal loss is detected for a given channel, the playlist associated with that channel can be loaded and played by the device. The device can resume playing the channel when the signal is again adequately detected.
