摘要： PROBLEM TO BE SOLVED: To rationally select the physical channel of the optimal broadcasting.
SOLUTION: In determining the optimal physical channel, viewing based on a reception result by a first antenna unit is secured, and a physical channel corresponding to a second antenna channel is successively switched to a plurality of physical channels for performing the same content broadcasting as that of the physical channel under viewing. Then, when the physical channel corresponding to the second antenna channel is matched with the physical channel under viewing, the receiving state related with the physical channel under viewing is collected on the basis of the reception results of all antennas belonging to the first or the second antenna units. On the other hand, when the physical channel corresponding to the second antenna unit is not matched with the physical channel under viewing, the reception state of the physical channel as the object of collection is collected on the basis of the reception result of the antenna belonging to the second antenna unit. Then, the optimal physical channel is determined on the basis of the collection result.

摘要： PROBLEM TO BE SOLVED: To decode a plurality of pieces of image encoded data which are encoded and packetized by systems different for each service, while speedily switching them without sense of incompatibility.
SOLUTION: In decoding of a high quality motion picture service using an MPEG2 decoder, an information storage processing means makes an access unit correspond to a PTS including presentation time information that is specific information of the access unit, from a stream of a simplified motion picture service (such as one-segment broadcasting) and stores them. When a switching control section performs switching control from the MPEG2 decoder to an H264 decoder, the H264 decoder decodes access units in order from the latest IDR access unit stored in the information storage processing means and when a PTS judgment section judges a case where a presentation time indicated by the PTS comes later in the future rather than a decoding completion time, the H264 decoder completes synchronization processing and shifts to ordinary decoding processing. Thus, a synchronization processing completion processing time of the H264 decoder is remarkably shortened.

摘要翻译：要解决的问题：解码由每个服务不同的系统编码和分组的多个图像编码数据，同时快速地切换它们而不感觉不相容。解决方案：在使用MPEG2解码器的高质量运动图像服务的解码中，信息存储处理装置使得访问单元对应于包括作为访问单元的特定信息的呈现时间信息的PTS，简化的动态影像服务（如单段广播）并存储。当切换控制部分执行从MPEG2解码器到H264解码器的切换控制时，H264解码器从存储在信息存储处理装置中的最新IDR访问单元的顺序解码访问单元，并且当PTS判断部分判断出呈现由PTS指定的时间稍后将来，而不是解码完成时间，H264解码器完成同步处理并转换到普通解码处理。因此，H264解码器的同步处理完成处理时间显着缩短。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a digital broadcast receiver capable of automatically detecting a viewing area, or the like.
SOLUTION: A database part 15 for storing the whole station data table MEM 1 composed of data of the whole viewing areas in the country and broadcasting stations corresponding to each viewing area and a control part 14 for controlling reception are provided. The control part 14 performs reception by seek operation or scan operation, acquires area identification data transmitted from a broadcasting station while included in broadcast and corresponding to a viewing area and retrieving the data of the viewing areas stored in the database part 15 with the area identification data to thereby judge the viewing area in which a digital broadcast receiver 10 is located, setting the viewing area.

摘要： PROBLEM TO BE SOLVED: To select a best antenna for each channel. SOLUTION: When a seek instruction is received, a diversity circuit 90 detects any of 1st-4th antennas 1-4 denoting a best reception state at a frequency set by sweeping, based on a reception state of the antennas 1-4, and a system microcomputer 20 discriminates the end of channel selection, based on the best reception state of the antenna detected by the diversity circuit 90, then even when the respective antennas has a frequency characteristic to any channel, the seek is much more ensured, as the seek is stopped by a station with excellent quality.
