IPC: H04L12/70
Filed: 1991-11-22
Abstract: PURPOSE:To reduce the packet transmission time by allowing a sender side terminal equipment to send a packet comprising compressed communication information and control information and allowing a receiver side terminal equipment to receive only a packet addressed to itself and decoding the communication information. CONSTITUTION:A CPU 9 stores communication data to a RAM 11 and stores control data to a ROM 10. Data from the RAM 11 are compressed by a compression section 3 and combined with data from the ROM 10 at a combined section 4 and a packet is sent to a transmission line 2 from a transmission section 5. A reception section 6 of other terminal equipment on the transmission line 2 receives a packet only when an address included in the control data is addressed to itself, a separating section 7 separater the data and sends the control data to the CPU 9 and the communication data to a decoding section 8. The decoding section 8 decodes the compressed data and sends the result to the CPU 9 and the CPU 9 applies decoding processing to the control data and the communication data. Thus, the packet transmission time is reduced and the transmission efficiency is improved.

Title: Color luminance separation type multi-channel coding transmission system
Inventor: HAMANO TAKASHI
IPC: H04N11/04
Filed: 1988-12-01
Abstract: PURPOSE:To decrease deterioration in a picture and to avoid deviation to a channel with a low abort rate of information quantity to be sent by differentiating a frequency band separating a low frequency component and a high frequency component from a chrominance signal and a luminance signal. CONSTITUTION:A 1st coefficient separator 2A separates a low frequency component and a high frequency component as to a luminance signal shared by a selector 6 at a prescribed frequency band. Then a 2nd coefficient separator 2B separates a low frequency component and a high frequency component as to a chrominance signal shared by the selector 6 at a prescribed frequency band different from the case with the 1st coefficient separator 2A. Moreover, as the coefficient separators 2A, 2B, a conversion table such as ROM is used. A high frequency component coder 4 applies, e.g. in-frame coding to each high frequency component of a luminance signal and a chrominance signal as the result of orthogonal conversion and the high frequency component coder 4 has a quantizer 41. Since the band separating the low frequency component and the high frequency component obtained as the result of orthogonal conversion differs from the chrominance signal and the luminance signal being components of the picture information, the deterioration in the picture is less and the information quantity to be sent is not deviated.
