  Method for multiplexing of parallel information streams in a CDMA system - Patent 5831978
The method of claim 2 wherein the overhead bits are multiplexed to the channel encoded bits such that the overhead bits comprise a first channel frame of the at least one channel frames.
However, the bit rate of each data stream cannot be independently chosen because the sum of the bit rates cannot exceed the nominal rate for the code channel.
The bits of each information stream 10 to be transmitted arrive during a given frame interval T.sub.f and are multiplexed by a multiplexer 20 into a stream of common information frames 25.

 Bitstream - Wikipedia, the free encyclopedia
A bitstream or bit stream is a time series of bits.
A bytestream is a series of bytes, typically of 8 bits each, and can be regarded as a special case of a bitstream.
This usage may have originated based on the common method of configuring the FPGA from a serial bit stream, typically from a serial PROM or flash memory chip, although most FPGAs also support a byte-parallel loading method as well.

 Apparatus for using a receiver model to multiplex variable-rate bit streams having timing constraints - US Patent ...   (Site not responding. Last check: 2007-11-02)
Each bit stream is either a priority one, priority two, or priority three bit stream, with priority one bit streams being required to meet the time constraints set in the bit stream, priority two bit streams being required only not to underflow, and priority three bit streams being permitted to underflow.
Bit stream analyzer 809(i) collects information from bit stream 109(i) and applies receiver model 811(i) to the collected information to determine what rate is required by the condition of the receiving device.
Serial bit stream 1001(i) from SWIF receiver 1001(i) is modified by PCR 1005(i) and is output to packet director 1101, which detects packets, determines their types, and outputs them to the various components of channel input block 1009(i).

 Optical bit interleaving - US Patent 6771910   (Site not responding. Last check: 2007-11-02)
This requires, in the interleaved bit stream, the bits of one component bit stream to be timed to occur close to midway between the bits of the other component bit stream.
In the case of interleaving two 20 Gb/s bit streams to produce a single 40 Gb/s combined bit stream, the bit period of the 40 Gb/s bit stream is 25 ps, and hence the required timing precision is that the timing error between the two 20 Gb/s bit streams shall be to within ±1 ps.
Then, with the bits of one of the first stage interleaved bit streams all having an SOP orthogonal with respect to that of all of the bits of the other first stage interleaved bit stream, the method of the present invention is directly applicable to perform the second stage interleaving, i.e.

 Random Bits: Streams
A stream is a construct that delivers a potentially infinite series of values.
Because streams are potentially infinite, they cannot be filtered or mapped by applying a predicate to all of their values.
Streams can also be used to provide an abstract and functional interface to mass data storage.

 Good Experience - Bit literacy: an overview
All of bit literacy can be distilled into a simple philosophy that allows people to regain their life, free from information anxiety, while still living in the bits.
Instead, concentrate on letting go of the bits that find their way to you; the few remaining bits will be all the more valuable to you as a result.
Ten years ago we engaged bits through a "user interface" on a "personal computer." But the bits were bottled up, not very engaging, and couldn't touch us except when we sat in front of the screen.

 Memory MAYHEM! Memory, Byte Ordering and Alignment   (Site not responding. Last check: 2007-11-02)
the first bit is the one on the left, it is bit 0, and it is the least significant bit in the array (which is a byte).
The next bit after the most significant bit in the most significant byte is the least significant bit in the least significant byte in the word.
So the first bit we see is the first bit in the least significant byte in the word and the last bit we see is the most significant bit in the most significant byte in the word.

 Interface conversion device - Patent 5592653
Up to four frames of the serial data stream coming from this second line receiver is stored in a first memory module, it being possible to read this memory module in such a way that the data from the eighth and ninth serial data streams can be demapped and transmitted via eight standard type interfaces.
A fourth serial data stream F4 with a standard 2 Mb/s interface is received and is applied to a second interface converter IC2 which, after the eight bits of each of the 32 channels with this standard interface, inserts another 8 bits without information.
The same pair of the second frame would occupy bits 2 and 3; the same pair of the third frame would occupy bits 4 and 5; and the fourth frame would occupy the last two bits 6 and 7 of the first channel of the 512 kb/s standard interface.

 Streams - Super Soaker Central
Stream physics are so important, and yet so many people seem to ignore it or just be ignorant to the facts.
A stream too small will be affected by drag too much because there is less water in the stream and the velocity will be higher.

 RFC 2032 (rfc2032) - RTP Payload Format for H.261 Video Streams
The bits resulting from the Huffman encoding are arranged in 512-bit frames, containing 2 bits of synchronization, 492 bits of data and 18 bits of error correcting code.
The result of the hierachical structure of H.261 bit stream is that one needs to receive the information present in the frame header to decode the GOBs, as well as the information present in the GOB header to decode the MBs.
The bit stream cannot be fragmented between a GOB header and MB 1 of that GOB.

 3 Bit Manipulation (bits.hhf)
If you want to compute the number of bits in an eight-bit operand it's probably faster to write a simple loop that rotates all the bits in the source operand and adds the carry into the accumulating sum.
These routines merge two streams of bits to produce a value whose size is the combination of the two parameters.
This function takes the L.O. n bits of source, where n is the number of "1" bits in mask, and inserts these bits into dest at the bit positions specified by the "1" bits in mask.

 About Bits   (Site not responding. Last check: 2007-11-02)
Yes, the economy of bits is driven by bit architecture and by the constraints that we impose upon them by means of storage and delivery mediums.
By making small changes on the bit level, and how the packets are configured, and a few other changes concerning power, we can end up going from 10 and 100 Mbps up to transferring speeds of 1 and 10 Gbps.
All of this goes to show that the idea that the economy of bits is driven by the bit architecture that we set up and by the constraints imposed by storage and delivery mediums is true.

 FLEXI-STREAMS - Flexible bivalent streams for Common Lisp
It is an input stream if the underlying binary stream is an input stream, and it is an output stream when the underlying binary stream is an output stream.
A flexi stream always has an external format associated with it which is deployed whenever you read characters from the stream or write characters to it.
The library also provides in-memory binary streams which are modeled after string streams and behave very similar only that they deal with octets instead of characters and the underlying data structure is not a string but either a list or a vector.

 A Vatful of Fluid: Unitstreams
Superficially, setting potential on the line to either low or high can be thought as sending a bit, but actually the bitstreams sent this way are very limited - namely only streams with alternating bits can be encoded this way.
By that I mean that a timestamped sequence of units [(), (), ()] corresponds to one of the two timestamped sequences of bits: either [0, 1, 0] or [1, 0, 1].
Networks rely on the fact that peers are usually not moving fast enough relatively to each other, so their local clocks are good enough to recover timestamps that are not sent explicitly.

Each of these elements is called a "bit", and they flow at the "bit rate", described as 9600 bits/sec or sometimes "9600 baud" depending on the context.
Since the FO-20 bit rate is 1200 bps, this means that most of the signal occupies an effective RF bandwidth of the order of 2.1 kHz, so it stands a fair chance of passing through the SSB receiver filters without significant distortion.
The isolated bit shape is zero at all T points except at one, and this leads to a nice 'scope trace.

 The Bits Between The Lambdas: Binary Data in a Lazy Functional Language - Wallace, Runciman (ResearchIndex)   (Site not responding. Last check: 2007-11-02)
Abstract: For the programmer, storage media are usually assumed to have a minimum atomic unit of transfer of one byte.
However, sometimes it is useful to have an even finer storage granularity of one bit, for instance in order to compress data.
This paper describes an API in the lazy functional language Haskell for treating storage media as arbitrary-length streams of bits, without byte-alignment constraints.

 Challenge my assumptions!
In particular, you could represent binary tree sentences in your current system using _Streams of size 2 to represent application (the binary construct) and streams of bits to represent the words.
But, on the other hand, all sentences in your system could be written in a binary tree language also.
A map could be represented as a list ("stream") of pairs; there is no need for an additional _Bag construct either (you can simply represent unordered sets using ordered ones, or if it needs to be clear, have a header at the front ("FOO" or "BAR") that tells whether it is ordered or not).
