Abstract: A content recommendation device includes: a use information storage section storing types of information related to use as information related to use of content by a user; a recommended content deciding section deciding content to be recommended to the user in accordance with each of the types of information related to use as a recommended content, and deciding types of recommended content items corresponding to the types of information related to use; a switching rule storage section storing a switching rule setting a period for switching the type of the recommended content as a rule set by a regional manager who is in charge of selling content in a specific region; a selection section selecting one type of the recommended content among the types of recommended content items when a recommended content suggestion request is generated from a terminal of the user residing in the specific region, and sequentially selecting different types of content after the period set by the switching rule; and a recommended i

Abstract: In a multiplexer, a channel selection controller determines which channel code is to be selected for a control data generator, each of multiplex buffers, and null packet generator, a PTS/DTS controller replaces PTS with DTS in a program being multiplexed, an output controller reads and deliver TS at a time synchronous with a system clock, and a virtual decoder buffer simulates each of T-STD buffers as in MPEG2.

Abstract: An encoding-multiplexing apparatus capable of reliably transmitting input data having high priority in accordance with priority information of input data and a receiver which decodes data transmitted from the encoding-multiplexing apparatus, in accordance with the priority information can be realized. In an outer encoding section 33, an error correction code having error correction ability according to the priority information of the input data is added to the input data in order to generate a fixed-length packet and moreover, said priority information is written in at a prescribed position of the fixed-length packet. Then, a plurality of packets are multiplexed and transmitted. The receiver extracts only a packet of a desired program from the plurality of packets and also, extracts priority information from the extracted packet, in order to perform a decoding based on the priority information.

Abstract: A method for encoding error correcting codes to generate plural coded data having different error correction ability according to significance. An error correcting code having different code length is added to a fixed length of input data according to the significance of the input data (S14). The error correcting codes added which have different error correction ability corresponding to its code length are encoded to generate coded data having different packet length according to the code length of the error correcting code. Thus, plural coded data (S15A and S15B) which have different error correction ability according to significance can be generated. Thereby, even if a quality of transmission system deteriorates when the above coded data is transmitted, the coded data having high error correction ability can be surely decoded.

Abstract: It is intended to determine widths of quantization of respective encoders to prevent deterioration in quality of picture in its entire aspect. A multi-coding apparatus comprises a plurality of encoders 1a to 1n for coding input data at variable rates, a bit allocator 4 supplied with estimated amounts of codes output from the respective encoders 1a to 1n, and a maximum transmission rate controller 3 for supplying a whole allocated amount of bits to the bit allocator 4 on the basis of the amounts of codes output from the respective encoders 1a to 1n.

Abstract: A PCR is detected from a bit stream by a PCR extracting circuit. When the time reference value is detected, an STC counter counts a clock oscillated by a VCO and compares the value of the STC counter and the value of the PCR. The phase difference is fed back to the VCO through a digital filter. In the control start stage, the gain of the digital filter is designated to a large value. Thus, the phase difference is quickly converged to the allowable difference range. In the lock stage, the gain is designated to a small value. Thus, the control operation is stably performed. In the nearly unlock stage, the gain is designated to a middle value. Thus, the phase difference is quickly pulled to the allowable difference range.
