Description

  The present invention relates to a playback apparatus including a display unit that displays a list of received contents or a list of contents stored therein.

  In recent years, many radio stations (content distribution servers) have been established on the network, and the number of contents provided from these radio stations has become enormous. Various types of playback devices (for example, Internet radio devices, personal computers equipped with Internet radio software, etc.) for receiving and playing broadcasts (content distribution) from these radio stations have been proposed (for example, , See Patent Documents 1 and 2).

  The radio apparatus described in Patent Document 1 uses a search unit that searches for a server that distributes sound information via a network using an IP address that is uniquely assigned to a server connected to the network, and a user operation. When the IP address set by the IP address setting unit and the IP address set by the address setting unit do not match the IP address of the server searched by the search unit, an interoffice sound corresponding to the difference between these IP addresses is generated. It has a configuration including an inter-station sound generation unit to generate. With such a configuration, the user can easily find and receive broadcasts of radio stations established on the network.

  In addition, the information distribution system described in Patent Document 2 includes an Internet radio station including a plurality of Internet radio station servers that distribute program content information, and a program for searching for the contents of the program content information from each radio station server. When a program search request for searching for desired broadcast contents is made from the Internet radio device to an information providing system including a broadcast contents search server having search information, the broadcast contents search server responds to this request. Thus, the Internet radio apparatus is provided with a search result including an Internet radio station server that delivers contents satisfying the search condition. With such a configuration, the Internet radio apparatus can easily find an Internet radio station server desired to be distributed.

JP 2002-158598 A

  In the radio apparatus described in Patent Document 1, a user can easily find and receive a broadcast of a radio station established on a network by setting an IP address by a user. However, when displaying a program guide transmitted from a received radio station, if there are many content lists included in the program guide, the program guide list cannot be displayed on the display screen at once. . Therefore, there is a problem that the user has to search for the desired content by operating the operation unit of the radio device and scrolling the program guide on the screen.

  In the information distribution system described in Patent Document 2, when an Internet radio apparatus makes a program search request, information on the Internet radio station server that satisfies the search condition is transmitted from the broadcast content search server. Thereby, by accessing a desired Internet radio station server, the program guide can be received from the server. However, when the received program guide is displayed, if the number of content lists included in the program guide is large, the program guide list cannot be displayed on the display screen at one time. There has been a problem in that it is necessary to search for a desired content by operating the operation unit of the Internet radio apparatus and scrolling the program guide on the screen.

  That is, in the case of the radio device described in Patent Documents 1 and 2 above, when displaying a list of received program listings, it is necessary to display all the list listings and sequentially send them by scrolling or the like. There is a problem that the operation for viewing the image is troublesome. In addition, such scrolling display has a problem that if the scrolling is too fast, the content to be reproduced may be overlooked and skipped. Furthermore, simply displaying the received program guide will not allow you to guess where in the program guide the content you want to play is located, and eventually you will be able to find all of the program guide in every corner. There was also a problem that we had to search while checking.

  The present invention was devised to solve such problems, and its purpose is to display a list of received contents or a list of contents stored in the list at a time when the list is displayed on the display unit. It is easy to search the list of the desired contents by reducing the amount of content, so that the so-called page unit is switched, and the pseudo antenna is tuned by rotating the antenna in old analog broadcasting. Is to provide a playback device that excels in operability while stimulating the user's sense of fun.

  In order to solve the above-described problem, the playback device of the present invention is a playback device including a display unit that displays a list of received or stored content, and has a size that can be displayed on the display screen of the display unit. When the page size is set, a page dividing unit that divides the received or internally stored content list into a plurality of pages with the one page size and stores it in a list storage unit is provided separately from the apparatus main body. Page switching means connected to the apparatus main body via wired or wireless communication means, and display switching control means for switching the page of the divided list displayed on the display unit according to the operation of the page switching means, The page switching means is composed of a pedestal portion installed in the vicinity of the apparatus main body and a pseudo antenna portion that rotates on the pedestal portion. The display switching control means is characterized to switch the page of division list being displayed on the display unit in accordance with the rotation operation of the pseudo antenna unit.

  That is, according to the present invention, the page dividing means divides the received or internally stored content list into a plurality of pages with one page size and stores them in the list storage unit. The page of the division list displayed on the display unit is switched according to the operation of the switching means. In this way, by reducing the number of lists to be displayed at one time so as to fit within one page size, and sequentially switching and displaying the divided pages, it is possible to easily search for a list of desired contents without omission, and Can be done quickly.

  Further, in the present invention, the page switching means includes a pedestal portion installed in the vicinity of the apparatus main body and a pseudo antenna portion that is rotated on the pedestal portion, and the page switching is performed by rotating the pseudo antenna portion. To do. In other words, the operation of rotating the pseudo antenna is a similar operation to rotating and fine-tuning the antenna in various directions in order to better capture analog broadcast radio waves. The operation for the list search can be enjoyed.

  Further, according to the present invention, the page switching unit includes a rotation operation detection unit that detects a rotation operation of the pseudo antenna unit on the pedestal unit, and the display switching control unit detects the operation of the rotation operation detection unit. It is configured to control page switching of the division list based on the signal.

  The pseudo antenna portion is rotatably supported such that its rotation axis is inserted into an insertion hole provided in the center portion of the pedestal portion. For example, the rotation motion detection unit includes a plurality of switch terminal units arranged concentrically with a predetermined interval (or a predetermined rotation angle) around the insertion hole of the pedestal unit, and a rotation axis of the pseudo antenna unit. It consists of one provided contact terminal, and this contact terminal sequentially contacts the switch terminal portion as the rotating shaft rotates due to the rotation of the pseudo antenna, so that the page of the divided list is switched each time the contact is made. It can be configured.

  Further, according to the present invention, the page switching means includes a rotation direction detection unit that detects a rotation direction of the pseudo antenna unit, and the display switching control means is based on a direction detection signal of the rotation direction detection unit. It is configured to control page-up or page-down of divided pages.

  For example, the rotation direction detection unit includes a switch terminal unit included in the rotation operation detection unit as a set of two terminals, a first terminal and a second terminal. When the contact terminal contacts the second terminal after contacting the first terminal (that is, immediately after receiving the first signal indicating that the contact terminal contacts the first terminal, the display switching control means When the second signal indicating that the second terminal is touched is received), for example, it is determined that the rotating shaft is rotating in the right direction, and the contact terminal contacts the first terminal after contacting the second terminal. In the case (that is, immediately after receiving the second signal indicating that the contact terminal is in contact with the second terminal and receiving the first signal indicating that the contact terminal is in contact with the first terminal) The rotation direction of the pseudo antenna can be detected by determining that the rotation is in the left direction. Therefore, the display switching control means can control the page up or page down of the divided pages by confirming the detection order of the first signal and the second signal. For example, when it is determined that the rotation is to the right, the page is increased, and when it is determined that the rotation is to the left, the page is decreased.

  In the present invention, the page dividing unit may be configured to arrange the list in the order of 50 sounds based on the file name of the content and sequentially divide the list into one page size by this arrangement.

  With such a configuration, by arranging the content list in the order of the syllabary, the user can specify which page of the list the content is based on, for example, the file name of the content to be searched. The search can be performed more quickly.

  Further, in the present invention, the page dividing means may be configured to arrange a list from the latest one based on the delivery date and time of the content and sequentially divide the list into one page size by this arrangement.

  With such a configuration, by arranging the contents in order of distribution date and time, for example, when searching for the latest distributed contents, it is only necessary to look at the first page of the divided list, so the search time is greatly increased. Can be shortened.

  In the present invention, operation input means operated by a user is provided, and the page dividing means arranges a list of contents for each artist based on the artist name input by the operation input means. You may comprise so that it may divide | segment sequentially into 1 page size.

  With such a configuration, the user can easily search for the desired content by displaying the page of the desired artist.

  In the present invention, the page dividing means arranges a list in the order of 50 sounds based on the file name of the content, and sequentially divides the list into one page size in this arrangement, and the distribution date and time of the content. A list is arranged from the latest one based on the second division function for sequentially dividing the list into one page size in this arrangement, and a list of contents is arranged for each artist based on the artist name of the contents. A third division function that sequentially divides into page sizes, and a selection unit that selects any one of the division functions may be provided in the pedestal portion of the page switching unit. Here, the selection means may be a selection button provided individually for selecting each function, or a rotary knob for selecting each function by a rotating operation.

  In this way, by providing the selecting means in the pedestal portion, the user can freely select the list arrangement. That is, since the list arrangement can be freely selected according to the user's usage pattern, it is possible to provide a list display that is extremely convenient for the user.

  <Description of page switching means 21>

  2 to 4 show an example of the configuration of the page switching means 21, FIG. 2 and FIG. 3 (a) are explanatory views seen from the front, FIG. 3 (b) is a plan view seen from above, FIG. 4 (a) is a cross-sectional view seen from the front, and FIG. 4 (b) is a cross-sectional view taken along the line AA in FIG. 4 (a).

  The page switching means 21 of the present embodiment includes a pedestal portion 22 formed in the shape of a truncated cone installed in the vicinity of the apparatus main body 1a, and a pseudo antenna portion 23 formed in a loop shape rotated on the pedestal portion 22. Thus, the control unit 12 switches the program guide page displayed on the display unit 18 in accordance with the rotation operation of the pseudo antenna unit 23.

  That is, as shown in FIG. 4, the page switching unit 21 includes a rotation operation detection unit 31 that detects the rotation operation of the pseudo antenna unit 23 in the pedestal unit 22, and the control unit 12 includes the rotation operation detection unit 31. The divided program guide pages are switched based on the operation detection signal.

  The pseudo antenna portion 23 is rotatably supported such that the rotation shaft 24 is inserted into an insertion hole 25 provided in the center portion of the pedestal portion 22. In the pedestal portion 22, a disc-shaped ring portion 32 made of an insulating material portion arranged horizontally concentrically with the insertion hole 25 as a center is provided. On the ring portion 32, a predetermined interval ( There are provided a plurality of switch terminal portions 33 arranged with a predetermined rotation angle about the insertion hole 25. On the other hand, the rotating shaft 24 of the pseudo antenna portion 23 is provided with a single support rod 26 extending in the horizontal direction from the peripheral wall surface, and one contact terminal 35 is provided at the lower end of the support rod 26. Is provided. The contact terminal 35 is disposed on the same concentric circle as the ring portion 32 and is provided so as to contact the opposing switch terminal portion 33.

  That is, the rotation operation detection unit 31 includes a plurality of switch terminal units 33, 33,... Arranged on the ring unit 32, and one contact terminal 35 provided on the rotation shaft 24 of the pseudo antenna unit 23. It consists of As a result, the contact terminal 35 sequentially contacts each switch terminal 33 along with the rotation of the rotating shaft 24 due to the rotation of the pseudo antenna 23, so that the control unit 12 that detects the contact signal detects the contact signal each time. The program guide page divided into two is switched.

  Further, the page switching means 21 includes a rotation direction detection unit that detects the rotation direction of the pseudo antenna unit 23, and the control unit 12 performs page up or page division of divided pages based on the direction detection signal of the rotation direction detection unit. It comes to control down.

  FIG. 5 shows the configuration of the rotation direction detection unit.

  The rotation direction detection unit is realized by configuring the switch terminal unit 33 constituting the rotation operation detection unit 31 with a pair of two terminals, a first terminal 33a and a second terminal 33b.

  That is, when the pseudo antenna portion 23 (that is, the rotation shaft 24) rotates in the right direction R (see also FIG. 3B), the contact terminal 35 is always brought into contact with the first terminal 33a and then to the second terminal 33b. Will be in contact. On the other hand, when the pseudo-antenna portion 23 (that is, the rotating shaft 24) rotates in the left direction L (see also FIG. 3B), the contact terminal 35 is always connected to the first terminal 33a after contacting the second terminal 33b. Will be in contact.

  Therefore, when the control unit 12 receives a second signal indicating that the contact terminal 35 has contacted the second terminal 33b immediately after receiving the first signal indicating that the contact terminal 35 has contacted the first terminal 33a. Immediately after receiving the second signal indicating that the pseudo-antenna portion 23 (that is, the rotating shaft 24) is rotating in the right direction R and the contact terminal 35 is in contact with the second terminal 33b. When the first signal indicating that the terminal 35 has contacted the first terminal 33a is received, it can be determined that the pseudo antenna unit 23 (that is, the rotating shaft 24) is rotating in the left direction L.

  As described above, the plurality of switch terminal portions 33, 33,..., Which is a combination of the first contact 33a and the second contact 33b, and one contact terminal 35 provided on the rotating shaft 24 of the pseudo antenna portion 23. In addition, it is possible to detect the rotation operation and the rotation direction of the pseudo antenna unit 23 (that is, the rotation shaft 24).

  In addition, the structure of the rotation operation | movement detection part 31 or a rotation direction detection part is not limited to the said structure, It is possible to use a conventionally well-known various structure. For example, although not shown in the figure, instead of the ring portion 32, a rotating disk having slits formed at predetermined intervals around the disk is arranged, and a transmissive photocoupler is vertically moved through the rotating disk. It is also possible to arrange so that the rotation operation and the rotation direction of the rotating disk are detected by the slit portion of the rotating disk crossing the optical path between the light emitting part and the light receiving part of the photocoupler.

  <Description of page division processing in control unit 12>

  When the size that can be displayed on the display screen of the display unit 18 is one page size, the control unit 12 divides the program guide received from, for example, a content distribution server on the network into a plurality of pages with one page size and stores the list. Stored in the unit 15.

  Here, a specific example of the process of dividing the program guide into a plurality of pages will be described.

  (Specific example 1)

  In this specific example 1, based on the file name (specifically, song name, etc.) of each content included in the program guide, the song titles are arranged in the order of the Japanese syllabary "Aiueo ...", and this page is one page. It is configured to sequentially divide into sizes (this is called a first division function). As a result, for example, the divided program table 1 (first page) lists the contents of the song title starting with the “a” line, and the program table 2 (second page) has the “ka” line as the initial. The contents of the song titles starting from are listed, the contents of the song title starting with the first letter “sa” are listed in the program table 3 (page 3), and the song titles are listed in the program table 10 (page 10). A program table divided into, for example, 10 pages in which contents of song titles starting from the “wa” line are listed is created. Therefore, the list storage unit 15 stores the program table (divided list) for 10 pages starting from each row in this way. In the above specific example 1 (first division function), the number of song title contents starting from each line is described as being contained in one page. However, if the contents do not fit in one page, naturally This is divided into two pages or three pages.

  In this way, by arranging the content list (song name) in the order of 50 notes, if the user knows the song name of the content to be searched, for example, the page contains which content from that song name. Therefore, it is possible to easily specify the program table including the song name on the display unit 18 and quickly find and reproduce the content to be reproduced.

  (Specific example 2)

  In the second specific example, the program table is arranged from the latest one based on the distribution date and time of the content, and the arrangement is sequentially divided into one page size (this is referred to as a second division function).

  Thus, by arranging the contents in the order of distribution date and time, for example, when searching for the most recently distributed contents, it is only necessary to look at the program table 1 of the first divided page, so the search time is greatly increased. It can be shortened.

  (Specific example 3)

  In the third specific example, a program table of contents is arranged for each artist based on the artist name input by the operation unit 17 and is sequentially divided into one page size by this arrangement (this is the first one). This is called the 3-split function.

  By arranging the program guide for each artist in this way, the user can display the program guide including the desired artist on the display unit 28 and easily find the content of the desired artist.

  Here, a selection unit that allows the user to select in which form the specific example 1 (first division function) to the specific example 3 (third division function) described above is used for the page division processing in the control unit 12. May be provided.

  FIG. 6 shows an example of this selection means.

  The selection means shown in FIG. 6A has selection buttons 41a to 41c for individually selecting any one of the first division function to the third division function on the base portion 22 of the page switching means 21. It is provided. The selection buttons 41a to 41c are push button type. That is, for example, when the user selects a page division process from a menu screen (not shown) displayed on the display unit 18 by operating the operation unit 17, the display unit 18 performs page division on any of the first to third division functions. In this state, when the user presses any one of the selection buttons 41a to 41c provided on the pedestal unit 22, the control unit controls the division according to the selected function. 12 will do.

  Further, the selection means shown in FIG. 6B has a rotary knob 51 for selecting any one of the first division function to the third division function by rotating operation on the pedestal portion 22 of the page switching means 21. Is provided. That is, the rotary knob 51 is provided with a pointer 51a. Around the rotary knob 51, switch terminals (not shown) are provided at three rotational positions indicated by the pointer 51a. The pedestal portion 22 is provided with character notation indicating the contents of the division function performed when each switch terminal is turned on and the respective points (marks) 55a, 55b, 55c, and 55d at the positions of these switch terminals. It has been.

  Here, the first point 55a indicates that the first division function is performed as the page division processing when the pointer 51a is rotated to this position, and the second point 55b indicates that the pointer 51a is at this position. This indicates that the second division function is performed as the page division processing when the pointer 51a is rotated to this position, and the third division 55 is performed as the page division processing. Indicates that the function is performed. The fourth point 55d is the home position position of the pointer 51a when the user does not select the page division process. When the pointer 51a is in this position, the default page preset in the present apparatus is used. Division processing (for example, a fourth division function that performs page division processing in the same order without modifying the received program guide) is performed.

  Thus, by providing selection means such as the selection buttons 41a to 41c and the rotary knob 51 on the pedestal portion 22, the user can freely select the program table arrangement conditions. That is, since the arrangement can be freely selected according to the usage pattern of the user, it is possible to provide a program table display format that is extremely convenient for the user.

  <Description of split list display processing>

  Next, in a state where the received program table is page-divided by any one of the above-described division methods and divided into 10 pages from, for example, the program table 1 to the program table 10 and stored in the list storage unit 15, A processing operation in which the program table stored in the list storage unit 15 is displayed on the display unit 18 and is sequentially switched by operating the unit 23 will be described with reference to the flowchart shown in FIG. This processing operation is executed by the control unit 12.

  When the user selects a program guide display process from a menu screen (not shown) displayed on the display unit 18 by operating the operation unit 17 (when it is determined Yes in step S1), the display unit 18 includes a list storage unit. For example, the program guide 1 of the first page stored in 15 is displayed (step S2).

  In this state, the control unit 12 starts monitoring whether a contact signal is input from any one of the switch terminal units 33 (step S3).

  Thereafter, when the user or the pseudo antenna unit 23 is slowly rotated, for example, in the right direction R, the contact terminal 35 provided on the rotating shaft 24 comes into contact with the first switch terminal unit 33 adjacent in the right direction (step S3). Is judged as Yes).

  When the control unit 12 receives a contact signal from the switch terminal unit 33 due to the contact of the contact terminal 35, the control unit 12 determines whether or not the contact signal is the first signal from the first terminal 33a (step S4). If it is the first signal (if determined as Yes in step S4), it is next determined whether or not the contact signal input immediately thereafter is the second signal from the second terminal 33b. (Step S5). As a result, if it is determined that the input contact signal is the second signal from the second terminal 33b (Yes in step S5), the pseudo antenna unit 23 is rotated in the right direction R to switch It is determined that the terminal unit 33 has been touched. In this case, page up processing is performed (step S6), and the next page program table (that is, the second page program table 2) is displayed on the display unit 18. Then (step S10), the process returns to step S3.

  On the other hand, in step S4, when the contact signal from the switch terminal portion 33 due to the contact of the contact terminal 35 is not the first signal from the first terminal 33a (when determined No in step S4), then It is determined whether or not the contact signal is the second signal from the second terminal 33b (step S7). If the contact signal is the second signal (if determined Yes in step S7), then It is determined whether or not the contact signal input immediately after is the first signal from the first terminal 33a (step S8). As a result, when it is determined that the input contact signal is the first signal from the first terminal 33a (when determined Yes in step S8), the pseudo antenna unit 23 is rotated leftward L to switch It is determined that the terminal unit 33 has been touched. In this case, page down processing is performed (step S9), the next page program table is displayed on the display unit 18 (step S10), and the process returns to step S3.

  Here, as shown in FIG. 8, the divided multi-page program table can be turned endlessly (page switching). That is, when the page is switched to the forward direction P1 by rotating the pseudo antenna unit 23 in the right direction R, the page returns to the first page when going from the first page to the tenth page. When the page is switched in the reverse direction P2 by rotating 23 in the left direction L, the page returns to page 10 again from page 10 to page 1. Accordingly, the display of the program guide of the previous page in step S10 in this case is the display of the program guide 10 of the 10th page.

  Whenever the pseudo antenna unit 23 is further rotated and the contact terminal unit 35 comes into contact with the adjacent switch terminal unit 33 and receives a contact signal from the switch terminal unit 33, the control unit 12 The process of step S10 is repeated.

  In addition, when it is judged No in each of step S5 and step S8 (that is, when the first signal and the second signal are not continuously detected), and when it is judged No in step S7 (that is, If it is determined that the contact signal from the switch terminal 33 is neither the first signal nor the second signal), error processing is performed without doing anything (for example, an error has occurred during operation on the display unit 18) The program guide display process is terminated.

  In the above embodiment, a description will be given of a configuration in which a program guide received from an Internet radio station or the like is uniquely divided and stored in the list storage unit, and the page of the program guide displayed on the display unit 18 is switched by the page switching means 21. However, for example, a list of file names of various data such as documents, charts, moving images and still images stored in a large amount in a personal computer database is uniquely divided and stored in the list storage unit 15, and page switching means It is also possible to configure to switch the page of the file name list of each data by 21.
