    Abstract: PROBLEM TO BE SOLVED: To provide techniques to seamlessly switch reception between multimedia programs and stream. SOLUTION: For continued decoding, a wireless device continues to receive, decode, decompress and display a current program, even after a new program has been selected, until overhead information needed to decode the new program is received. After receiving the overhead information, the wireless device decodes the new program but continues to decompress the current program. The wireless device decompresses the new program after decoding this program. For early decoding, the wireless device receives a user input and identifies a program with potential for user selection. The wireless device initiates decoding of the identified program, prior to the selection of the identified program, so that the identified program can be decompressed and displayed earlier if it is subsequently selected.

    Abstract translation: 要解决的问题：提供在多媒体节目和流之间无缝切换接收的技术。 解决方案：为了继续解码，即使在选择了新程序之后，无线设备继续接收，解码，解压缩和显示当前程序，直到接收到解码新程序所需的开销信息。 在接收到开销信息之后，无线设备解码新程序，但是继续解压缩当前程序。 解码该程序后，无线设备解压缩新程序。 对于早期解码，无线设备接收用户输入并识别具有用户选择潜力的程序。 无线设备在选择所识别的节目之前启动所识别的节目的解码，以便如果随后选择已识别的节目，则可以更早地解压缩并显示所识别的节目。 版权所有（C）2011，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method for performing local transmission and wide area transmission in a wireless broadcast communication network. SOLUTION: In order to perform broadcast communications of transmission of different type having a hierarchy with different communication-possible range in a wireless broadcast communication network, each base station processes data for the wide area transmission according to a first mode (or coding scheme and modulation scheme) (S812), and processes data for the local transmission according to a second mode (S813). Based on each desired communication-possible range for the wide area transmission and the local transmission, each of the first mode and the second mode is selected. In the same way, each base station multiplexes the data for the local transmission with the data for the wide area transmission without overlapping partially, and carries out broadcast communication for the multiplexed data.

    Abstract: PROBLEM TO BE SOLVED: To facilitate the efficient reception of each data stream by transmitting overhead information. SOLUTION: A base station transmits many data streams on many data channels (MLC). The MLCs are transmitted at different times and on different frequency sub-bands. The overhead information represents a time-frequency position of each MLC, and is sent as "composite" overhead information and "embedded" overhead information. The composite overhead information represents the time-frequency positions of all the MLCs and is periodically sent in each superframe. A radio device receives the composite overhead information, determines the time-frequency position of each MLC and receives each MLC at the represented time-frequency position. The embedded overhead information of each MLC represents the time-frequency position of an MLC in the next superframe and is transmitted together with a payload of the MLC in the current superframe.

Based on each desired communication-possible range for the wide area transmission and the local transmission, each of the first mode and the second mode is selected. Each base station performs the broadcast communication on the local transmission and the wide area transmission as well as pilots related to them, based on different characteristics for a multi-frequency network and a single network.
