Apparatus for receiving and displaying continuously updated data
First Claim
1. Apparatus for receiving an encoded data stream comprising a plurality of data groups as transmitted from a remote location and for selectively accessing the received data stream to sort out and store only those data groups of interest, each data group of the encoded data stream includes its unique identifying word, the encoded data stream includes a classifier manifestation indicative of a protected data group, said apparatus comprising:
- (a) decoder means for receiving and decoding the transmitted, encoded data stream;
(b) temporary storage means coupled to said decoder means for sequentially receiving and temporarily storing, one at a time, at least said identifying word of each received and decoded data group of the data stream;
(c) updateable, addressable memory means for storing a plurality of those data groups of interest and their identifying words at corresponding, addressable locations therein; and
(d) control means comprising comparing means coupled to said temporary storage means and said updateable, addressable memory means for accessing the identifying word currently stored in said temporary storage means and each of said identifying words of the data groups of interest and for comparing the temporarily stored, current identifying word with each of the identifying words of the data groups of interest, updating means responsive to said comparing means and operative in a first mode, between the currently stored identifying word and one of the identifying words of the data groups of interest for effecting the storage of the data group corresponding to the currently stored identifying word in that location of said updateable, addressable memory means in place of the previously stored group of interest corresponding to the one matched identifying word, and in a second mode if a match is not made between the groups of interest to discard from said temporary storage means the received and decoded data group, and classifier means settable with a classifier manifestation means for effecting a comparison of the transmitted classifier manifestation of the data stream and the set classifier manifestation and, if a comparison is made therebetween, for accessing and transfering the protected data group to said temporary storage means and, if a comparison is not made therebetween, for discarding the protected data group.

Abstract
Receiving and displaying apparatus is disclosed for receiving a continuously transmitted stream of encoded data messages, whereby selected of the data messages are stored in an updateable, addressable memory having a plurality of locations, one for each of the selected data messages. Each of the data messages has its unique word identifying the nature of the data message. In particular, the receiving and displaying apparatus includes a temporary storage means wherein each data message and in particular, its identifying word is stored and means for comparing the temporarily stored identifying word with the identifying word of each of the data messages as presently stored within the locations of the addressable memory. The comparing means operates to successively compare the temporarily stored identifying word with the identifying words as stored with each of the plurality of locations and if there is a match, for updating the matched location with the new data message and if a match is not made, to discard that incoming data message.

31. Apparatus for receiving and processing transmitted blocks of data, each data block including an access manifestation whereby said apparatus may gain access to said data block, said apparatus comprising:
-
(a) decoder means for receiving and decoding said encoded data blocks; (b) temporary storage means coupled to said decoder means for receiving and temporarily storing at least said access manifestation of each incoming data block; (c) processor means for selectively processing said data blocks; and (d) access means comprising means for receiving a card having an access manifestation thereon to provide a signal indicative of the card'"'"'s access manifestation, means coupled to said temporary storage means and to said card receiving means for accessing the access manifestation of the incoming data block and the card'"'"'s access manifestation signal, means coupled to said accessing means and said receiving means for comparing the card'"'"'s access manifestation signal with the transmitted access manifestation, and data transfer means coupled to said decoder means and to said processor means and responsive to said comparing means and operable in a first mode if a match exists between the access manifestation of the incoming data block and the card'"'"'s access manifestation signal for transferring the incoming data block to said processor means for further processing, and in a second mode if a match is not made between the access manifestation of the incoming data block and the card'"'"'s access manifestation signal, to discard the incoming data block from said temporary storage means.

32. A process for repetively transmitting a first number of updated data groups from a central location to a plurality of locations remote from said central location, each data group indicative of a changing item, said transmitting process comprising the steps of:
-
(a) establishing a storage file of said first number of data groups; (b) continuously monitoring the changing items to provide and store an updated data group in said storage file in place of the corresponding, former data group; (c) assigning to each data group a unique word identifing its item; (d) repetively transmitting from said central station one of said plurality data groups at a time; (e) receiving at each of said remote locations said plurality of repetively transmitted data groups; (f) identifying at each of said remote locations a second number of items of interest less than said first number of data groups; (g) comparing at each remote location said identifying word of each received data group to said identifying word of each item of interest to provide a set of updated data groups of interest at each remote location. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39)
