摘要： An FM receiver for receiving a text-based multiplex broadcast includes a decoder for taking out text-based program data from a multiplexed signal received at a receiver circuit and a controller having first and second memory areas. Data taken out by the decoder is alternately written to the first and second memory areas each time a power supply is turned on. When the power supply is turned on, the controller reads out data from one of the first and second memory areas that is carrying out writing of the data, and displays a text-based program at a display element with this read-out data. The memory area carrying out the reading of data is then alternately changed over between the first and second memory areas upon the operation of a prescribed key.

摘要： A wireless output input device (WOID) digital audio player for storing and/or receiving digital audio and preserving the digital stream without the inherent distortion of translating the stream to analog prior to modulation and transmission, which includes an FM receiver, and an FM transmitter for transmitting the audio to an external FM radio or receiver. The device automatically and periodically scans a plurality of channels on the FM band to determine the channel having the least amount of interference and then tunes the FM transmitter to the frequency of that channel and displays the channel to which the external receiver should be tuned. A remote control may be provided to selectively transmit signals to the player's FM receiver for controlling operation of the player.

摘要： A method and system are provided for remultiplexing program bearing data. The remultiplexing method and system are applicable to MPEG-2 compliant transport streams carrying video programs. A descriptor based system is used for scheduling the timely output of transport packets wherein each descriptor records a dispatch time as well as a receipt time for each transport packet. The receipt time is used for estimating program clock reference adjustments, but final program clock reference adjustment is performed in hardware in relation to the precise output timing of each transport packets. A descriptor and transport packet caching technique is used for decoupling the synchronous receipt and transmission of transport packets from any asynchronous processing performed thereon. The descriptors can also be used for managing scrambling and descrambling control words (encryption and decryption keys). Remultiplexing functions may be distributed across a network. The remultiplexer can furthermore optimize the bandwidth of transport streams by replacing null transport packets with transport packet data to be inserted into the output transport stream. Program data transmitted via asynchronous communication links is re-timed and assistance is provided for outputting program data on such asynchronous communication links to reduce a variation in end-to-end delay incurred by the program data. Remultiplexing and program specific information can be seamlessly dynamically varied without stopping, or introducing a discontinuity in, the flow of outputted transport packets. A technique is also provided for locking multiple internal reference clock generators.
摘要翻译：提供了用于对程序承载数据进行再多路复用的方法和系统。再复用方法和系统适用于承载视频节目的符合MPEG-2标准的传输流。基于描述符的系统用于调度传输分组的及时输出，其中每个描述符记录调度时间以及每个传输分组的接收时间。接收时间用于估计节目时钟参考调整，但最终的节目时钟参考调整在硬件中相对于每个传输分组的精确输出定时进行。描述符和传输分组缓存技术用于将传输分组的同步接收和传输与其上执行的任何异步处理去耦。描述符也可用于管理加扰和解扰控制字（加密和解密密钥）。多路复用功能可以分布在网络上。再多路分解器还可以通过用要插入到输出传输流中的传输分组数据替换空传输分组来优化传输流的带宽。通过异步通信链路发送的节目数据被重新定时，并且提供帮助来输出这种异步通信链路上的节目数据，以减少由节目数据引起的端到端延迟的变化。重新复用和节目特定信息可以无缝地动态地变化，而不会停止或引入输出传输分组的流的不连续性。还提供了用于锁定多个内部参考时钟发生器的技术。

摘要： A method of assigning a channel identification (ID) of an audio signal by which it is possible to follow up and select the audio channel selected by a user even though a program or an audio data stream is changed in an audio/video (A/V) device for reproducing a program including a plurality of audio data streams, a method of selecting audio channels using the same, and an apparatus suitable therefor. The method of selecting the audio channels of an A/V data stream including a plurality of programs, each program including at least two kinds of audio data streams, each audio data stream including at least two sub-audio data streams which are not repeated and having a series of IDs according to a predetermined order of precedence, the method including (a) when a program is changed to another program, searching whether there is a sub-audio data stream having a channel ID which is the same as the channel ID assigned to the sub-audio data stream of the program which was being reproduced before the program was changed, in the changed program, and (b) when it is determined that there is the sub-audio data stream having a channel ID which is the same as the channel ID assigned to the sub-audio data stream of the program which was being reproduced before the program was changed in the step (a), selecting the sub-audio data stream. According to the method of selecting the audio channels, it is possible to follow up a voice mode selected by a user (maintain the previously selected audio channel) although a program or an audio data stream is changed.

摘要： A method and system for specifying channels for data sent upstream in a data-over-cable system, including data leaving the data-over-cable system is provided. The data sent upstream from an application has a corresponding group-identification parameter, also referred to as a flow-identification parameter. This parameter specifies a particular channel on which the data is to be forwarded. This specification is based on a correspondence between the data-identification parameter and a channel-identification parameter assigned to the channels over which data-packets are transmitted. The data-over-cable system may use the data-identification parameter to allocate access to a channel as part of a Quality-of-Service request. This parameter also allows sorting of data-packets for further transmission upstream, including possible bundling to form groups of data-packets and subsequent transmission upstream.

摘要： A method and system for communicating state information for a target consumer electronic device in a home network to multiple controller devices, where the controller devices are each implementing a controller software element that conforms to a different protocol than the other. The target consumer electronic device is represented within the home network by a target software element. A first controller software element conforming to a data driven interaction (DDI) protocol accesses the target software element. A second controller software element conforming to a protocol different from the DDI protocol concurrently accesses the target software element. The first controller software element and the second controller software element cause a change in state of the consumer electronic device. The target software element notifies the first controller software element and the second controller software element of the state information for the target consumer electronic device. The target software element notifies the first controller software element according to the DDI protocol and notifies the second controller software element according to the protocol different from the DDI protocol. The first controller software element and the second controller software element use the state information to manage their respective user interfaces such that consistency is maintained between the user interfaces.

摘要： A multi node network communications protocol which provides high information throughput at high efficiency, while also maximizing low probability of detection and interception characteristics by optimizing use of transmitting power and other characteristics including but not limited to modulation method, FEC rate and spread spectrum processing gain. The network is optimized by dividing into sub-networks and optimizing the sub-networks to consider local conditions, thus optimizing the overall network to a level of efficiency not possible from a central control point. A protocol which periodically adapts to changing conditions and allows silent entry and exit of nodes as well as providing locations of all nodes within the network.
