Title: Method and equipment for transmission of video bit stream
Inventor: GUREN ROORENSU KIYATSUSHIYU
IPC: H04N7/173
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To improve transmission quality by transmitting only L in high/low priority segments H/L through the use of agreed high priority information, obtaining H from a storage device on a reception side or generating it by means of a prescribed system and interleaving it with L on a real time basis. SOLUTION: A server 200 generates the high priority segments H by using high priority information A which is previously agreed and stores it in a disk 202. It stands by and receives video segments request. The server 200 and a client (CL) 220 set the non-guarantee distribution/reception protocols of data on the low priority segments L in the request segments. Then, the server 200 reads data on the segments L from the disk 202 or generates it on a real time basis based on information A and transmits it to CL 220 on a real time basis. A video CL processor 221 obtains data on the section H from the memory. A video decoder 224 interleaves data of the segments H and L and displays them on a monitor 225. Thus, the quality of video transmission by a packet network 210 can be improved.

Title: Ringing pre-trip testing system
Inventor: TODO KENTARO
IPC: H04M3/02
Filed: 1988-10-14
Abstract: PURPOSE:To prevent an erroneous answer, erroneous trip, and erroneous cache and, at the same time, to inform a maintenance person of a fault on a subscriber's line by previously detecting the fault of the subscriber's line. CONSTITUTION:When a control circuit CONT receives an instruction for sending ringing signals to a subscriber's terminal TEL, the circuit CONT operate a relay D and supplies -48V to the relay D from a detection circuit DET before controlling the sending of the ringing signals. When, for example, a fault of a subscriber's line, such as the ground-fault of a line B, etc., exists and the DC supplied to the relay D exceeds the threshold level of the circuit DET, the circuit CONT recognizes the fault as a subscriber's line fault and informs a central processor CP of the fault. The central processor CP processes the relevant call as a call loss by means of a storing program and, at the same time, causes a printer TTY to print the presence of the fault. Therefore, an erroneous answer, erroneous trip, and erroneous cache can be prevented and, in addition, a fault message can be informed to a maintenance person.
